Unrepresented AMD Ryzen 3 5300G hybrid processor appears on eBay

An AMD Ryzen 3 5300G quad-core hybrid processor based on the Zen 3 architecture has appeared on the eBay marketplace. The chip belongs to the desktop part of the Cezanne family, which AMD hasn't even officially introduced yet. Despite this fact, some sellers are already selling engineering samples of processors of this family. Earlier, for example, the same seller offered an eight-core Ryzen 7 5700G model;

Engineering sample Ryzen 3 5300G with identifier 100-000000262-30_Y has a base frequency of 3.5 GHz. The source of supply for the chip is unknown, but AMD and Intel routinely provide engineering samples to motherboard manufacturers as well as system integrators well in advance of the official release of the new processor series. The seller has priced the «engineer» at $177.

The product description initially stated that support for the processor was very limited, as many motherboards could not yet work with the Cezanne hybrid APU. He later added that the problem was the integrated graphics core, for which there was no proper driver, but one of the «indifferent fans» provided a beta driver. It is also offered along with the processor. In its current state, the AMD Ryzen 3 5300G engineering sample scores 570 points in the CPU-Z single-core test and 3003 points in the multi-core test. The vendor also provided test results for the chip in the Cinebench R15 and Cinebench R20 tests, but only in multicore mode. It scored 2,068 points in the former and 2,685 points in the latter & ; respectively.

He also posted a video showing the Ryzen 3 5300G engineering sample in use:

The previous series of hybrid processors on the Zen 2 (Renoir) architecture were distributed exclusively through OEMs of off-the-shelf systems. However, in some markets the chips still appeared as a separate product, albeit unofficially.

AMD prepares desktop Ryzen PRO 5000G - octa-core model is marked in CPU-Z

One of the users of Chinese forum Chiphell shared CPU-Z screenshot which confirms AMD plans to release AMD Ryzen PRO 5000G (Cezanne) series hybrid desktop processors for Socket AM4 socket. According to VideoCardz resource, this picture may indicate AMD Ryzen 7 PRO 5750G model specifications.

According to Chinese enthusiast, who provided the screenshot, AMD is not likely to release Ryzen PRO 5000G processors to official retailers. Instead, these processors will be intended exclusively for computer manufacturers (OEM) and system integrators.Recall that the manufacturer did the same with the previous generation of Ryzen 4000G (Renoir) series chips, which did not prevent them from appearing in retail stores. The illuminated sample of Ryzen PRO 5000G series has 8 cores and 16 virtual threads. The configuration of cores implies that we are looking at the Ryzen 7 PRO 5750G, as the younger Ryzen 5 PRO 5650G should offer 6 cores and 12 virtual threads.

The processor is not compatible with PCI Gen 4.0 interface and is equipped with Radeon graphics core, but Vega generation, not Navi, as many would like. Against the background of full desktop chips Ryzen 5000 series (Vermeer) hybrid chip has a smaller amount of Level 3 cache memory. However, this information is not new, because there are already on sale laptops based on mobile Ryzen 5000 (Cezanne) chips, which are based on the same crystals. Image source also reported that the latest version of the BIOS for ASUS Crosshair VIII motherboard does not have full support for this chip. It requires a firmware version based on newer AGESA 1.2.0.0 microcode. The Infinity Fabric Bus (FCLK) frequency of this sample is 2300 MHz, but some engineering samples of Ryzen 5000G hybrid processors have FCLK frequency up to 2500 MHz, which allows for DDR4 memory with effective frequency up to 5000 MHz. As for the clock speed range, the source says the processor can automatically overclock up to 4.05 GHz on all cores, but the owner was able to manually overclock it to 4.75 GHz. It is also noted that the chip comes with the same cooler as the Ryzen 7 5800X processor.

AMD unveils Zen 3 architecture for mobile Ryzen 5000 a huge jump in single-core performance and other improvements

AMD today lifted a ban on publishing details related to the Zen 3 architecture, which is the basis of the Cezanne range of Ryzen 5000 mobile processors. At the disposal of resource VideoCardz were promotional images and graphics, describing the features of new chips.

AMD announced that the production of new mobile chips based on Zen 3 architecture, it has started just a few months after introducing mobile processors on the Zen 2 architecture. The new Cezanne APU and the previous Renoir APU have a lot in common, with Zen 3 computing cores being the main focus of the upgrade;

The manufacturer claims "historic increases in single-core performance" in the new Cezanne chips. The new flagship mobile Ryzen 9 5980HX has a 23% single-core performance advantage over the previous generation Ryzen 9 4900H flagship, as well as a 19% single-core performance advantage over the Intel Core i9-10980HK competitor Ryzen 9 5900HX. The company helped to achieve these results by optimizing Zen 3 architecture, as well as a noticeable increase in the chip's clock speeds relative to the previous generation of Renoir processors. AMD points out that chip area of Cezanne hybrid processors has increased by 15% over its predecessors to 180 mm2. The fresh APUs are based on 10.78 billion transistors, which is 10 percent more than the previous generation chips. The Cezanne chipsets use a single eight-core CCX (Core Complex). In addition, the new chips have doubled the amount of Level 3 cache memory. This increased to 16 MB, and now is equally distributed to all CPU cores. Additionally AMD works on memory controller, providing it with LPDDR4X support with up to 32 GB capacity and dual channel mode support. Graphics core remains the same old one - it is the same 7nm Vega with eight compute units (CU, Compute Units) that was used in Renoir mobile processors (Ryzen 4000). The increase in graphics performance in this case will be mainly due to the increased limiting frequency of the graphics core, which now stands at 2.1GHz. The company has also worked on the power saving capabilities. Voltages are now managed separately for each core to reduce the overall power consumption of the entire processor. This optimization results in two additional hours of battery life for the new Ryzen 5000 mobile system. New notebooks based on the latest AMD mobile processors will be available from major manufacturers in February 2021. Some laptop models with Ryzen 5000H and 5000U series chips are already available for pre-order.

AMD Ryzen 9 5900HX is fastest mobile processor in PassMark test

AMD Ryzen 9 5900HX tops the list of fastest mobile CPUs according to PassMark. Curiously enough, this chip is not the flagship of the new Cezanne series (it is Ryzen 9 5980HX). Nevertheless, the Ryzen 9 5900HX has been ranked as the fastest processor in both single and multi-core performance.

To recap, Ryzen 5000 mobile processors are divided into four categories:

U-series processors with 15W TDP & ; designed for ultra-portable laptops; HS-series processors c TPD 35W & ; high-performance chips for thin gaming notebooks; H-series processors with 45W TDP & ; high-performance processors; HX-series processors with TDP 45W & ; get unlocked multiplier.

The eight-core Ryzen 9 5900HX with an unlocked multiplier runs from 3.3GHz to 4.6GHz. It is differentiated from the Ryzen 9 5980HX by a 200MHz reduced Boost frequency. Ryzen 9 5900HX is designed to be used in premium gaming laptops with the most advanced components. These include the latest ASUS ROG Zephyrus and Strix models. According to PassMark, Ryzen 9 5900HX, tested with ASUS ROG Strix SCAR 17 G733 gaming notebook, scored 24,039 points in multi-threaded benchmark, beating out any other mobile processor tested in this benchmark.

Moreover, AMD showed best single threaded performance with 3365 points. Ryzen 9 5900HX beats all Intel Tiger Lake-U chips, and also flagship H-series Core i9-10980HK, which also has unlocked multiplier. AMD has officially unveiled eight Ryzen 5000H series processors. What's interesting is that the Ryzen 9 5900H, which was shining in the notebook line-up before the official announcement, was not among them. At the moment, it's unknown whether AMD intends to release it.

Mobile AMD Ryzen 7 5800U has been found to have multi-threaded performance issues in synthetic tests

Network sources have shared performance results of AMD Ryzen 7 5800U mobile processor in GPU-Z and Cinebench synthetic tests. Recall that Ryzen 5000 series chips on the Zen 3 architecture will be presented next week. It will include both power efficient Ryzen 5000U models with limited to 15W TDP, and high-performance Ryzen 5000H with a claimed power consumption level of 45W.

The Ryzen 7 5800U belongs to the first category of the aforementioned processors. This processor belongs to the Cezanne family and is built on the Zen 3 architecture. It should also be added that the Ryzen 5000 series will include chips from the Lucienne family, built on the Zen 2 architecture, which are Refresh versions of the current mobile Renoir (Ryzen 4000). The Ryzen 7 5800U has 8 cores and 16 virtual threads and runs in the 2.0-4.4GHz frequency range. Compared to its predecessor Renoir series, the novelty on Zen 3 gets twice the amount of cache memory of Level 3, 16 Mbytes. In addition, the Ryzen 7 5800U has 200 MHz higher base and Boost frequency compared to its predecessor. In CPU-Z synthetic test, Ryzen 7 5800U processor scored 592 and 3812 points in single-threaded and multi-threaded tests respectively. Interestingly, in the first case, the performance of AMD's mobile chip was even higher than the current flagship desktop Intel Core i9-10900K, which scores 584 points in the same test. The red's multi-threaded performance, on the other hand, is disappointing. Even the current Ryzen 7 4800U scores over 5000 points in this test. Whether this is due to problems with simultaneous multi-threading (SMT) or to a "raw" BIOS of the laptop's motherboard, which uses a Zen 3 chip, is unknown. In Cinebench R20, the Ryzen 7 5800U scores 509 points in the single-threaded test and 3,614 points in the multi-threaded test. In the fresh Cinebench R23 shows scores of 1311 and 9326 in the respective tests. Thus Ryzen 7 5800U is 6% faster in single-threaded Ryzen 7 4800U but slower in multi-threaded test.

AMD Cezanne's Zen 3 mobile processor chip image has been published - the chip is larger than Renoir's

An image of AMD's Cezanne hybrid processor chip has been made available to VideoCardz resource. Recall that new mobile chips series Ryzen 5000 will be presented next week. The series will include chips that use two architectures at once: Zen 3 (Cezanne) and Zen 2 (Lucienne).

According to the source, Cezanne APU will be able to offer up to 8 compute cores and 16 virtual threads, as well as up to 8 Radeon graphics cores, like the current generation of mobile Renoir (Ryzen 4000). The total number of PCIe lanes will not change either - Cezanne will get 20 lanes. The mobile Renoir (Ryzen 4000U/H) has only 8 of the 20 PCIe lanes dedicated to discrete graphics, the desktop Ryzen 4000G has 16. Earlier it was rumored that the next generation of Cezanne processors would receive PCIe 4.0 interface support. Whether it will appear in AMD's chips, which will be unveiled next week, remains a mystery as well. A quick comparison of Renoir and Cezanne chip sizes indicates that the area of the latter is larger. VideoCardz calculates that the new processors should have 175 mm2, which is 19 mm2 more than the Renoir (156 mm2). The increase in chip area is due to the use of slightly larger Zen 3 cores, as well as a larger L3 cache block. According to available information, AMD's upcoming next-generation mobile APUs will get 16 Mbytes of L3 cache memory, which is double the size of the current Renoir. The announcement of the Ryzen 5000 hybrid mobile processors is very likely to take place on January 12. The series will include both energy-efficient Ryzen 5000U (Zen 2) chips and high-performance Ryzen 5000H (Zen 3) gaming models. And only the latter will be able to offer a significant performance boost over the Renoir processors.

AMD Ryzen 5 5600H based on Zen 3 is much faster than its predecessor

AMD is set to unveil its latest Cezanne processors in just three weeks at CES 2021, according to circulating rumours. The company will announce a family of low-power and high-performance mobile solutions that will be marketed under the names Ryzen 5000U and Ryzen 5000H.

Gigabyte to unveil G7, G5 and A7 entry-level notebooks with GeForce RTX 3060 and AMD and Intel chips

Gigabyte's new low-cost laptops are expected to go on sale next month. They will be unveiled in January at CES 2021 right after the announcement of new AMD mobile processors and next-generation NVIDIA graphics cards.

The G5 series & ; are 15-inch laptops with state-of-the-art Intel Core 10th generation processors (Comet Lake-H). The devices will get Core i7-10870H or Core i5-10500H CPUs. In addition, the G5 will offer a 1080p panel at up to 240Hz. This gaming laptop will be equipped with GeForce RTX 3060 Ampere graphics with 6GB of GDDR6 video memory.

The 17-inch G7 model will get a Core i7-10870H processor. Later, Gigabyte may add additional options with other CPUs. The 17.3-inch IPS display will be able to offer a 144Hz refresh rate. The G7 will also use GeForce RTX 3060 mobile graphics.

Finally, the Gigabyte A7 model is quite interesting. It is the first laptop with a Ryzen processor from this manufacturer and one of the first in the world to reportedly get the latest Ryzen 7 5800H Cezanne processor (eight Zen 3 cores, 16 threads and Vega graphics). It is identical in design to the G7 series, so a direct comparison between these devices will be extremely curious. The laptop will also be equipped with a mobile graphics gas pedal GeForce RTX 3060, but, unlike Intel variants, there will be available models with a higher power graphics card Max-P.
