Announcing the Ryzen 7000 family of desktop processors, AMD CEO Lisa Su assured that no shortage is expected at the start of sales.In her opinion, everyone will be able to buy the new products after September 27.Commenting on the availability of Ryzen 7000 on sale, Lisa Su said: \"If you look at the situation over the past 18 months, you can see a lot of problems, whether it's a lack of production capacity or logistical disruptions.Right now, on AMD's part, we've had a serious increase in production volumes in terms of both semiconductor wafers and wafers.So in the case of the Zen 4 launch we do not expect any supply constraints\".The Ryzen 7000 processors are scheduled for September 27, and AMD has a month to fill up supply channels.That's time AMD will spend, Lisa Su said, to get the new products to store shelves around the world and just in time. It is worth recalling that AMD has suspended the supply and official sales of its processors in Russia since the beginning of March.Therefore, new AMD processors may appear in local stores only through parallel import with some delay.Ryzen 7000 processors for desktops are based on Zen 4 architecture and due to IPC and clock speeds growth offer 29 % performance increase comparing to their predecessors.They support PCIe 5.0 and DDR5 memory.The lineup includes four models with the number of cores from 6 to 16 and price from $300 to $700.
AMD revealed plans: Ryzen 7000 with 3D cache, Threadripper on Zen 4 and all-new Zen 5
At last night's \"together we advance_PCs\" event, where AMD presented the Ryzen 7000 series desktop processors, some details about the company's future plans were revealed.In particular, the next architecture after Zen 4, Zen 5 will come to the market in 2024.As for the near future, the next big processor announcement from AMD is scheduled for next year - the beginning of next year, the company intends to present a family of mobile Ryzen 7000 processors based on the Zen 4 microarchitecture.Moreover, Mark Papermaster, AMD's technical director, promised during his speech that the Ryzen 7000 processors with additional 3D-cache chip (V-Cache), such as Ryzen 7 5800X3D, will be presented in the future.On the other hand, he refused to give a definite date for Zen 4 server versions with 3D V-Cache technology, but the timing was more definite: these processors will appear in early 2023.At the same time should go and designed for high-density servers processors EPYC Bergamo with Zen 4c-core - these chips, recall, will receive up to 128 cores, while the usual EPYC Genoa with the traditional architecture Zen 4 will be limited to 96 cores.Also AMD representatives mentioned the family of processors Ryzen Threadripper.According to David McAfee, vice president and general manager of customer channels, AMD is looking very closely at releasing Ryzen Threadripper processors on the Zen 4 architecture.However, due to changes in demand patterns and supply chains, we can only talk about variants \"without maximum configurations like Threadripper Pro, but with a broader lineup.\"In addition, David McAfee promised that the Ryzen 7000 desktop processor family will not be limited to four models and will expand.Additional processor models, covering a wider range of price categories, will be released early next year.As for the more distant prospects, the next to Zen 4 architecture Zen 5 is planned by AMD at the end of 2024, the processors based on it will be produced on the 4-nm process technology.According to Papermaster, Zen 5 is a \"complete redesign of the core with further optimizations for AI tasks.\"Along the way, AMD representatives have promised that the new platform Socket AM5, which comes out with the Ryzen 7000 processors, will remain relevant at least until 2025.And this means that motherboards with socket AM5 will support not only Ryzen 7000, but also promising Ryzen processors based on Zen 5 architecture.
AMD Ryzen 7 5800X3D has had its cover removed and solder replaced with \"liquid metal\" - temperature dropped by 10 °C
An enthusiast under the nickname Madness boasts of a successful operation to remove the cover from AMD Ryzen 7 5800X3D processor.After further testing we found out that scalping significantly improves chip's performance: performance increased, power consumption decreased and operating temperature decreased by 10°C.The game Forza Horizon 5 was used as a test load.Image source: twitter.com/Madness7771The operation was not easy: you had to push the blades of a paper knife through the edge of the lid, while feeding hot air at 150-200 °C from a heat gun.The procedure was strenuous.Having removed the lid, the enthusiast faced a choice: to replace the factory solder or to risk and install the cooler directly on the \"bare\" crystals.Madness chose the former - instead of solder Thermal Grizzly Conductonaut \"liquid metal\" was used.CPU readings before (left) and after (right) operationThe effort was not wasted.Under high loads Ryzen 7 5800X3D CPU showed 10°C lower temperature, slightly decreased power consumption, and clock speeds stabilized at the maximum value of 4450 MHz.This processor does not support overclocking, although, of course, it would be interesting to see the results of overclocking tests - scalping would obviously provide a lot of room for maneuver.
Ryzen 7 5800X3D Processor Overview: Final Point Socket AM4
Ryzen processors with 3D V-Cache technology, which expands cache memory with additional SRAM semiconductor crystal, were first mentioned by AMD exactly one year ago - at Computex 2021.And at that time, this announcement has created a real furore.On the one hand, through it AMD has confirmed its technological potential, as it showed its readiness to introduce an advanced technology of 3D-mounting of semiconductor chips and expand the chip design of its processors in the vertical direction.On the other hand, it has promised to significantly strengthen the Ryzen 5000 series by the end of 2021, adding a flagship 12-core processor with a giant cache and significantly increased performance in gaming applications.However, these Napoleonic plans - at least in their original form - were not fated to materialize.Promised Ryzen 9 5900X with 3D V-Cache technology never came out, and instead of it AMD released another consumer CPU with increased cache according to this technology - Ryzen 7 5800X3D.And it frankly looks a lot less spectacular. Firstly, Ryzen 7 5800X3D is just an octa-core CPU, which obviously cannot be a universal flagship solution, because 12- and 16-core solutions have been widely available in the desktop segment for a long time.Secondly, by the end of this year there will be more progressive processors based on Zen 4 microarchitecture in AMD's arsenal, which will almost certainly eclipse the Ryzen 7 5800X3D due to the IPC index growth and DDR5 SDRAM support.And third, with the introduction of the Alder Lake family late last year, the leadership in desktop processor performance has gone to Intel.Because Alder Lake offers higher specific performance than Zen 3, Ryzen 7 5800X3D now has to solve a completely different problem: it does not set new performance records in games, but only tries to catch up with competitor processors in an extensive way - by multiplying the amount of cache memory.In other words, the Ryzen 7 5800X3D output ended up being quite stripped out, and it seems that AMD lost a lot from the fact that it missed the deadline and made the model not at all what it promised.Nevertheless, that doesn't stop it from touting the Ryzen 7 5800X3D as \"the world's fastest gaming processor.\" However, there is a feeling that AMD overestimates the capabilities of its product: at least, many independent reviews could not confirm AMD's rightness in performance evaluations of the novelty.And for this reason we decided to test Ryzen 7 5800X3D with our own hands.Moreover it is not only unique by its design AMD processor, but also a kind of a final line in the history of Socket AM4 ecosystem: its development on Ryzen 7 5800X3D stops completely and no other CPU models will be available for this socket anymore.⇡# 3D V-Cache in detailsThe idea to expand cache capacity for better performance obviously did not come from AMD out of nowhere.Moving large amounts of data closer to the processor cores, which dramatically increases the speed of access to them - a fairly simple trick, which AMD liked before.AMD processors have long been distinguished by the amount of cache memory, and the company's marketing department uses the name Game Cache for it, explicitly stating that a capacious L3 cache is extremely useful for games.The opposite is also true: Ryzen processors with reduced cache, such as Ryzen 5 5500, have rather modest gaming performance.Ryzen 7 5800X3D is a processor where the idea of increasing cache capacity in the name of maximum FPS is taken to the absolute limit: it has 96 MB of L3 per eight cores (12 MB per core).But its main peculiarity is not even the impressive size of the cache, but the design, which is figuratively described in the model number of the processor with the ending \"3D\".It means that in the Ryzen 7 5800X3D cache is expanded with an additional 3D V-Cache crystal, which is physically superimposed on the original processor chip on top - in the third dimension.In words it sounds quite simple: an additional 64 MB SRAM chip is mounted on top of the 32 MB L3 cache present in the CPU chip and connected to it through connections.But in reality it is much more complicated. To place the superstructure in the form of a 3D-cache crystal on the processor chip, AMD had to work with TSMC on a special production technology, which would reduce the thickness of the combined from two parts - CCD (Core Complex Die) and 3D-cache - integrated device.As a result, it is reduced to the height of a single chip of conventional processors, so Ryzen 7 5800X3D fits into exactly the same package as other Ryzen family processors and does not require any special cooling systems or their mounts.This is achieved by two techniques.First
Ryzen 5 5500 processor review: affordable six-core that is late
It so happened that the Ryzen 5000 series release coincided with the crisis on the semiconductor market and the peak of chip shortage, as a result of which AMD had to severely limit the variety of model range.In November 2020, the company released only one model each with 6, 8, 12 and 16 cores, with the minimum price of a processor with Zen 3 progressive cores above $300.This approach displeased AMD fans, but the company had no other choice: the production quotas which it managed to get from its manufacturing partner, TSMC, were not enough even to cover demand for expensive processors.A year and a half passed since then, and the problem with the lack of production capacity for the manufacture of Zen 3 semiconductor chips weakened noticeably.But AMD did not hurry to expand the Ryzen 5000 lineup - the situation was quite good for it, because by selling more expensive processors it was increasing its profits.Yes, with this approach the users of low-cost systems had no opportunity to get processors with progressive microarchitecture at their disposal, but the company did not care much: it was quite successful in distributing obsolete solutions of Ryzen 3000 series among this audience.And these processors were also in high demand, because the alternatives, which until recently were offered by Intel, did not have serious competitive advantages.However, with the appearance of Alder Lake the situation has changed dramatically.Intel created a very successful processor family which was almost immediately available in all price segments.Because of this, it turned out that with the advent of 2022 there was nothing suitable in AMD's range that the company could counter the competitor's punchy processors like Core i5-12600K, Core i5-12400 and Core i3-12100, which very quickly came out on top in the sales statistics.So as soon as AMD realized that its market position had staggered and its share of the desktop market began to rapidly shrink, it immediately moved to retaliate.Firstly, it aggressively reduced prices on all available Ryzen 5000 series processors by 25-30%.Secondly, the lineup was replenished at once with several new products - available eight- and six-core carriers of the Zen 3 microarchitecture. Thus, since the beginning of April, sales of the $300 Ryzen 7 5700X eight-core and two six-core models: the $200 Ryzen 5 5600 and the $160 Ryzen 5 5500 started on the global market.Unfortunately, in Russia, which is now cut off from direct supplies, these models arrived with a noticeable delay and not at the prices AMD intended for them.But nevertheless, the most affordable CPU among the new products, Ryzen 5 5500, still looks interesting.In \"normal life\" it should be the cheapest six-core with modern microarchitecture, but in the current reality its Russian price is approximately equal to the cost of the youngest six-core Alder Lake, Core i5-12400, which is still quite good.That is why the 3DNews lab immediately started a detailed testing of this promising product as soon as the opportunity presented itself.It is worth to remind that AMD has already tried to produce such budget six-core units, which became the cheapest variants in their class, for example Ryzen 5 3500 and 3500X.However, they were only available in certain geographical regions and also had significantly reduced specifications.In Ryzen 5 3500 and 3500X, for example, the company turned off SMT technology, which was a big hit to performance.But the new Ryzen 5 5500 is a completely different breed of processor.It is globally available, the SMT technology is in place, and the main difference from the older brothers is the reduction of cache memory, which at first glance does not look catastrophic loss and makes familiarity with it only more interesting.⇡#Ryzen 5 5500 in detailsThe Ryzen 5000 lineup has undergone very noticeable changes this spring.Now there are eight representatives instead of four.The expansion took place mainly \"downwards\", but among the new models there is also the innovative Ryzen 7 5800X3D with 3D V-Cache technology, which is positioned by the company as a kind of gaming flagship.The composition of the family is listed in the table below, and, pay attention, a separate column - \"Current price\" is added to it.It shows retail prices of Ryzen 5000 family members on the world market after the occurred price reduction (in Russia, of course, the situation with prices is different, and there is no point in discussing it within the scope of this article).Cores/threadsFrequency, GHzL3, MbytesTDP, Wofficial priceCurrent priceRyzen 9 5950X16/323,4-4, 964105$799$559Ryzen 9 5900X12/243.7-4.864105$549$399Ryzen 7 5800X3D8/163.4-4.592105$449$449Ryzen 7 5800X8/163.8-4.732105$449$349Ryzen 7 5700X8/163.4-4.63265$299$
Tesla Model 3 based on AMD processors got less range than Intel
The AMD Ryzen processor-based infotainment system originally appeared aboard the older Tesla Model S and Model X electric cars, but it's now being used by the younger cars in the line & ; the Model 3 and Model Y. Some customers have noted that the company has notified them of the electric cars' reduced range because of this change.
Previously, the Tesla Model 3 and Model Y's onboard system was satisfied with Intel Atom processors, which, against AMD Ryzen, had lower power consumption, though at the same time were inferior in speed. Modernization of onboard electronics, as noted by the resource InsideEVs, required Tesla in some regions of sales of electric cars to notify customers about changes in the consumer qualities of the delivered products & ; for example, it happened in Australia. The upgraded electric car Tesla Model 3 with AMD Ryzen processor on board, as explained, is able to drive 602 km on the conditional WLTP cycle, 22 km less than with the old multi-media complex. In general, depending on the type of drive, traction battery capacity and the size of the wheels, as noted by the source, the range of the Tesla Model 3 can be reduced by a value of 11 to 22 km. Curiously, the Tesla Model Y has survived this upgrade without any losses. On the contrary, the range of this crossover even increased by the value from 26 to 34 km on the conditional WLTP cycle. This can be explained by the presence of a higher-capacity battery or other optimizations related to energy consumption. In this case, the appearance of the more voracious AMD Ryzen processor simply did not affect the range to the extent that it is observed in the Tesla Model 3.
Engineering samples of AMD Ryzen 7000 8- and 16-core processors on Zen 4 Raphael have been discovered on the Distributed Computing Network
Despite the fact that AMD Ryzen 7000 desktop chips on the Zen 4 architecture will not hit the market until the second half of the year, their engineering samples have already been found in business. And they were not used to mine cryptocurrencies, but to work in a network of voluntary distributed computing.
Two AMD Family 25 series models on the Zen 4 Raphael architecture have surfaced on the MilkyWay@Home distributed computing project website, where volunteers provide their home machines to process astrophysical data. Two chip names with different OPN codes (model designations), one 8-core and one 16-core, appeared in the database:
AMD Eng Sample: 100-000000665-21_N [Family 25 Model 96 Stepping 0] & ; 16 cores / 32 threads; AMD Eng Sample: 100-000000666-21_N [Family 25 Model 96 Stepping 0] & ; 8 cores / 16 threads.
In spite of the fact that one of the positions in chip description is written as «number of processors» in reality we are speaking not about cores, but about threads. For example, opposite the 16-core Ryzen 9 5950X, 32 «CPUs» are listed in the base. Opposite the item «Cache» for both chips of the Raphael family is a value of 1024 kBytes, and this is twice as much as the L2 cache of the processors on Zen 3 Vermeer. Systems with the new chips connected to the network anonymously, and it is not quite clear for what purpose they were used in this project, because voluntary distributed computing MilkyWay@Home on the BOINC platform can hardly be called a reliable benchmark.
As a reminder, AMD Raphael processors are expected to be released in the second half of the year. They will run on the all-new AM5/LGA1718 socket with DDR5 and PCIe Gen5 support. Recently, the company also assured that AM5 platform will be supported for a long time & ; at least not less than AM4.
Two Chinese Zen-based CPUs beat AMD Ryzen 5 5600X in multi-threaded test
China's EJ Hardware video blog tested a duo of Chinese Hygon C86 3185 processors that are little known outside the country. The Zen architecture chips are produced as part of a joint project between AMD and Hygon the Chinese company has been licensed to produce the processors domestically.
Hygon C86 processors are manufactured using 14nm technology, and the line includes mainstream and server models from 4 to 32 Zen cores. Externally Hygon C86 are almost indistinguishable from AMD Ryzen and EPYC. What's more, they should fit AM4 and SP3, though in most cases they come soldered to the motherboard. Last year's Hygon C86 3185 chip has 8 Zen cores with multi-threading support (SMT), base clock speed is 2.0 GHz, peak & ; 3.4 GHz. The L2 cache capacity is 4 Mbytes, L3 & ; 16 Mbytes. In fact, the C86 3185 is an analogue of the Ryzen 7 1700X with a lower clock speed & ; they even have the same TDP (95W). In the comparison tests a motherboard with two C86 3185 processors soldered, that is 16 cores Zen was used. The server motherboard had some limitations: in particular, the memory frequency was locked to DDR4-1866 and there was no option to increase it. In the other corner of the ring» was the Ryzen 5 5600X processor: 6 cores Zen 3, the base clock speed 3.7 GHz and peak 4.6 GHz. This processor is made on 7nm technology, and its TDP is lower by 30W.
In single-core performance Ryzen 5 5600X was the clear leader & ; first generation Zen cores simply didn't stand a chance against Zen 3. In single-core Cinebench R20 and R23 tests American chip was 97% and 135% ahead. But in multi-core tests Cinebench R20 and R23 the leader was Hygon with the results 12 % and 13 % higher accordingly. In Blender and x264 HD Benchmark, C86 3185 was also better & ; it showed 23 % and 33 % less performance than Ryzen 5 5600X. But in PCMark 10 American chip was ahead by 59 %. Decent results Hygon C86 3185 showed in gaming test, the role of which went to Cyberpunk 2077. Combined with GeForce RTX 3080 Ti the processors provided adequate frame rates in both 1080p and 4K. The reviewers concluded that the undoubted advantage of the American processor is the newer Zen 3 architecture, although in multi-threaded tasks the opponents behave almost equally & ; in any case, the difference is not significant. Although China in this joint project aims not to break performance records, but to gain at least relative independence from foreign technologies.
