AMD has banned the use of Power Play Table (PPTable) in the Windows registry on its Radeon RX 7000 graphics cards.This limits the overclocking capabilities of the graphics cards and, in particular, prevents fine-tuning GPU power and frequency curves outside of their official specifications.This has been pointed out by well-known enthusiast Buildzoid.Image source: AMDThe Power Play tables are an alternative method of changing GPU clock frequency, power and voltage via the Windows registry instead of modifying or replacing the BIOS.At the same time, it is the safest method of running GPUs outside of their official specifications, as it prevents any risk that may arise from BIOS re-flashing.Setting up Power Play tables or changing the BIOS has several advantages over traditional AMD overclocking methods and features offered by Radeon Software Adrenalin.First, users can bypass GPU hardware limitations associated with the firmware and overclock the graphics card as much as possible.Secondly, Power Play tables allow for fine-tuning of the voltage/frequency curve to improve the power efficiency of the graphics card.In other words, this method allows you to fine tune the video card's GPU behavior in more detail, which is not possible with AMD's usual overclocking software.Last generation Radeon RX 6000 video cards do not have the ability to fine tune power via Power Play tables blocked.Why AMD decided to prohibit access to it on Radeon RX 7000 video cards is unknown.However, one AMD engineer on the Reddit forum in a thread discussing power consumption issues with Radeon RX 7000 graphics cards reported that \"architecturally RDNA3 has some changes in how to manipulate the power tables.\"

Bloggers and media showed unboxing Radeon RX 7900 XTX and RX 7900 XT - reviews will appear on December 12
AMD allowed core media and tech bloggers to publish materials with unboxing of the latest graphics cards Radeon RX 7900 XTX and RX 7900 XT, reports VideoCardz.However, reviewers can not publish information about their performance or reviews - it will have to wait until next week.Image source: VideoCardzThe majority of reviewers got their hands on a reference version of the Radeon RX 7900 XT and Radeon RX 7900 XTX.While at first glance the two cards don't seem to differ from each other, a closer look reveals that this is not the case.The flagship Radeon RX 7900 XTX is slightly taller and longer than the Radeon RX 7900 XT.In addition, the video cards have a different RGB backlight configuration.However, both benchmark gas pedals have the same thickness of two expansion slots.In addition, both video cards received two 8-pin connectors for additional power. Image source: Overclock3DIt is also known that Radeon RX 7900 XT and Radeon RX 7900 XTX use different circuit boards.The flagship model has a wider one.The older version uses a board marked D704, the younger one uses a board marked D702.It is obvious that apart from the size of the circuit boards the graphics cards also differ in their VRM power subsystems.However, more detailed information on this will be known after the novelties will be available for disassembly. Image source: TechPowerUpDirect comparison shows that the next-generation Radeon graphics cards are much more compact than the reference models GeForce RTX 4090 and GeForce RTX 4080, which themselves are considered compact solutions in the new series of NVIDIA gas pedals compared to non-reference versions. Image source: ComputerBaseIt is curious that among the media only one source has received a non-reference model of AMD graphics cards on the RDNA 3 architecture.British publication Overclock3D has shared a picture of XFX Radeon RX 7900 XTX MERC 310, images of which flashed quite recently. Source image: Overclock3DThe German edition HardwareLUXX, full independent reviews of the Radeon RX 7900 XT and Radeon RX 7900 XTX will begin to appear on December 12, the day before the actual start of new products.Recall that in the benchmark flagship Radeon RX 7900 XTX estimated at $ 999, the junior Radeon RX 7900 XT has a price tag of $ 899.The first uses a full-fledged GPU Navi 31 with 6144 stream processors and is equipped with 24 GB of GDDR6 memory.The second one is based on a \"cut down\" Navi 31 GPU with 5376 stream processors and 20 GB of GDDR6 memory.
NVIDIA - about burnt-out RTX 4090 connectors: 50 known cases, users' fault, but the case is under warranty
NVIDIA finally issued an official statement regarding the problem with melting 12VHPWR power connectors plugged into GeForce RTX 4090 graphics cards.After weeks of investigation, the company said the source of the problem was mating connectors improperly.NVIDIA said it knows of about 50 cases of melted connectors around the world.To date, the company has concluded that the common cause of the problem is that \"the connector was not fully inserted into the video card.\" In fact, similar conclusions were reached the other day by the experts of the YouTube channel GamersNexus, who conducted their own independent investigation.Above - incompletely inserted connector, below - fully inserted connectorThe company noted that it is studying different approaches that would allow users to make sure that the connector is connected correctly before turning on the video card.So far, NVIDIA recommends first plugging the power connector into the graphics card, making sure it is fully inserted and has no gaps, and then plugging the graphics card into a PCIe slot on the motherboard.NVIDIA also noted that it is committed to supporting customers and providing a fast warranty process for graphics cards, \"regardless of the cable or card used.\"NVIDIA is still reviewing reports of melted connectors and looking for ways to ensure the card is properly connected to the power supply.At the same time, the company did not specify whether the latter would entail changes to the existing design or some other drastic measures.Also note that NVIDIA's statement about 50 cases indicates that the problem is not that widespread, given that NVIDIA and its partners have clearly sold tens, if not hundreds of thousands of GeForce RTX 4090s worldwide.
NVIDIA to unveil new GeForce RTX 40-series graphics cards Jan.3
At yesterday's quarterly event, NVIDIA management admitted to being quite pleased with the market debut of the first two members of the Ada Lovelace gaming architecture in the form of GeForce RTX 4090 and GeForce RTX 4080 graphics cards, but is soon going to introduce new models in the family.Now we found out that the next NVIDIA presentation will be held on January 3, at CES 2023.Source image: NVIDIAOn the eve of NVIDIA sent out the invitations to the press at a virtual event, which will be held during CES 2023 in Las Vegas, reports news resource PCMag.The presentation will be broadcasted on January 3 at 8 am local time.The only thing mentioned is NVIDIA's willingness to share information about \"cutting-edge innovations made possible by accelerated computing\".You can watch the broadcast directly on the official NVIDIA website.It is possible that the event in early January, among other things, will allow NVIDIA to bring back the relevance of GeForce RTX 4080 graphics card with 12 GB of memory, whose announcement was hastily canceled earlier.Most likely, this graphics solution will debut under another name, because earlier NVIDIA employees acknowledged the mistake of using the designation \"GeForce RTX 4080\" for two different graphics cards.It is assumed that the said graphics card with 12 GB of memory can go under the name GeForce RTX 4070 Ti with a price lower than the initially planned $ 899.The launch of AMD Radeon RX 7900 XTX ($999) and Radeon RX 7900 XT ($899) next month forces NVIDIA to think about countermeasures, which would not undermine profitability of GeForce RTX 4090 and GeForce RTX 4080.The appearance of a third video card in the family could well restore the balance of power.
NVIDIA says huge demand for RTX 4090 and RTX 4080 - the company is preparing many new GeForce RTX 40-series products
CFO Colette Kress took the opening remarks at the quarterly reporting conference NVIDIA called the past stages of debut of graphics cards with GPUs based on Ada Lovelace architecture extremely successful.GeForce RTX 4090 has been sold out in many markets since mid-October, the GeForce RTX 4080 is already on sale, and in general, NVIDIA is ready to offer \"many new products\" with this gaming architecture.Image source: NVIDIAThe last promise was made by the founder and permanent head of NVIDIA Jensen Huang (Jensen Huang).He stressed that now Ada Lovelace architecture carriers are positioned in the upper price segment.GeForce RTX 4090 graphics cards were released in large quantities, but this did not prevent customers from buying out their first batch in just minutes, as stated by the CEO of NVIDIA.The market, he said, has received both the GeForce RTX 4090 and GeForce RTX 4080 very favorably, and therefore management is very enthusiastic about this debut.In addition, it proves the strength, resilience and transparency of the gaming segment of the market, as summarized by the company's founder.In the third quarter of the current fiscal year, as explained by NVIDIA management in response to a related question from analysts at the quarterly event, the value equivalent of product inventory increased by $560 million sequentially.According to the company's CFO, this increase was only partly due to the need to accumulate a certain inventory of new architecture media: Ada Lovelace in the gaming segment and Hopper in c The networking segment, which is chiefly served by Mellanox products, also had a significant impact on the stock growth.The company had to write off $702 mn of stocks, but the bulk of these losses were accounted for by A100 computing gas pedals.Recall, the latter were intended for use in server systems by Chinese customers, but in the third quarter, after the new U.S.sanctions the company hastily offered them a replacement in the form of a chip A800, whose performance is limited at the hardware level, and therefore avoids the U.S.sanctions.As a result, demand from Chinese customers switched to new \"alternative solutions\" and part of the stock of old A100s had to be written off.As noted by NVIDIA executives at the quarterly event, the negative impact of sanctions in the third quarter was largely offset by the introduction of gas pedals A800 to the Chinese market, clearly adapted to the new U.S.export control requirements.
