The Radeon RX 7000 has been blocked from one of the most effective alternative overclocking methods

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.

AMD called Radeon RX 7900 XTX a competitor to GeForce RTX 4080, and announced FSR 3.0 compatibility with older graphics cards

PCWorld reporters managed to talk to Frank Azor, AMD chief gaming and marketing architect, and get some details about the Radeon RX 7000 graphics cards on the new RDNA 3 architecture.
AMD's representative said why at the time of the presentation of graphics cards Radeon RX 7900 XTX and RX 7900 XT novelties were not compared to models NVIDIA GeForce RTX 40-series.Image source: VideoCardzAccording to Mr.
Azor, AMD is positioning flagship gas pedal Radeon RX 7900 XTX as a competitor to the GeForce RTX 4080.
Since NVIDIA has not yet released the card, AMD had no information about the performance of the gas pedal to add to its comparison charts.\"[The Radeon RX 7900 XTX] is designed to compete with the RTX 4080.
We have no information about its performance.
This is the main reason why you didn't see any comparisons with NVIDIA solutions \u003C...> the $999 card can't be a competitor to the RTX 4090, which is rated 60% more expensive.
[The Radeon RX 7900 XTX's] competitor is the RTX 4080,\" Azor said.He also commented on the announcement of FSR 3.0 image scaling technology and noted that the decision to introduce a new version of FSR was not spontaneous.
According to him, FSR 3.0 will not only be supported by RDNA 3-based graphics cards.
\"Our decision to announce FSR 3.0 is not some kind of backlash or a desire to quickly introduce a competitor to NVIDIA DLSS 3.
We have been developing this technology for some time.
Why will it be available later than many would expect? The main thing is to remember the key philosophy behind FSR technology.
After all, FSR 1.0 and FSR 2.0 do not only work on RDNA and RDNA 2 graphics cards.
They are supported by other generations of AMD graphics gas pedals.
They are also supported by our competitors' graphics cards.
This is much more difficult to implement than if we just added FSR 3.0 support only for RDNA 3 graphics cards.
We really want FSR 3.0 to work on other graphics cards as well,\" Azor commented.Hinting at DLSS 3, which is only supported by GeForce RTX 40-series gas pedals, Azor added that support for just one architecture is much easier to implement.
However, AMD has made a promise that FSR will be supported by multiple graphics architectures.
But it takes time to implement this.
The company is not yet sure it can 100% keep that promise, but it will \"try very hard.\"

AMD introduced the Radeon RX 7900 XT and RX 7900 XTX graphics cards - the older one is priced at $999

AMD introduced its flagship gaming graphics cards Radeon RX 7900 XT and Radeon RX 7900 XTX.

New products are based on flagship graphics processor with RDNA 3 architecture, which AMD calls the world's first GPU with a chiplet design - it consists of several crystals. 

AMD's new flagship RDNA 3 architecture GPU includes 58 billion transistors, and their density has increased by 165% compared to previous-generation (RDNA 2) GPUs.

The big crystal in the center is made by 5-nm process technology and has an area of 300 mm2.It is called GCD (Graphics Compute Die) and includes all GPU computing blocks, as well as other necessary elements. Next to it are six small crystals with high speed memory Infinity Cache.

They are 6nm processors, have an area of 37mm2 each and are called MCD (Memory Cache Die).The bus bandwidth between GCD and MCD is 5.3 Tbytes/sec.

Note that Radeon RX 6000 had Infinity Cache memory on the same chip as GPU, but had 2.7 times less bandwidth. The new chips have a theoretical peak performance of 61 Tflops in single precision floating point operations (FP32), 2.7 times higher than the previous generation GPUs could offer (23 Tflops).

AMD notes that it optimized its computing block architecture for gaming, dramatically increasing performance.It also doubled the number of instructions executed per clock cycle, and increased the processing speed of ray tracing operations (by 50% for each processing unit) and artificial intelligence (by 2.7 times). 

 According to AMD, the new flagship Radeon RX 7900 XTX is 1.5-1.7 times faster in games than the Radeon RX 6950 XT.And when using ray tracing, which was not the strongest point of the last generation graphics cards, the performance increased by 1.5-1.6 times.

In general, AMD positions the new graphics card as a solution for 4K gameplay with high frame rate.And to achieve even higher frequency will help to scale FSR.Unfortunately, AMD did not compare its novelties with its competitors. Senior Radeon RX 7900 XTX has got graphics processor with 96 compute units (Compute Units, CU) with RDNA 3 architecture, which means there are 12,288 stream processors.

The chip runs at a clock speed of 2.3 GHz, which is the average frequency in games.Next to it is 96 MB of high-speed Infinity Cache memory, and the amount of GDDR6 video memory is 24 GB.It is connected via a 384-bit bus.

The graphics card power consumption is 355W. The subflagship Radeon RX 7900 XT has a graphics processor with 84 CU, which carry 10,752 stream processors.The average gaming frequency is claimed to be 2 GHz.The card has 80 MB of Infinity Cache memory, and the amount of GDDR6 video memory is 20 GB, and it is connected via a 320-bit bus.The consumption level of the card is 300 W.

The new AMD reference graphics cards have a cooling system with three fans and take up 2.5 expansion slots in height.

For additional power each has two 8-pin connectors.AMD separately pointed out that \"its new graphics cards won't need new chassis or new power supplies.\" This was obviously a kick in the teeth for NVIDIA, whose flagship GeForce RTX 4090 turned out to be huge, and also uses new 12+4 pin power connector. Also AMD emphasized on the new graphics cards support of the latest DisplayPort 2.1 interface.

It provides the ability to output images in 8K resolution at up to 165 Hz or in 4K resolution at 480 Hz.The problem so far is that there are no monitors with this interface and these characteristics on the market.Here we should also note the support of hardware acceleration when working with AV1 codec.

The recommended price of AMD Radeon RX 7900 XTX video card will be $999, while the junior Radeon RX 7900 XT is priced at $899.Both graphics cards will go on sale on December 13.

Recall that the GeForce RTX 4090 is priced at $1599, while the GeForce RTX 4080 will cost from $1199.

AMD to unveil Radeon RX 7000 graphics cards tonight

AMD will unveil Radeon RX 7000 graphics cards on the latest RDNA 3 architecture graphics processors tonight.
The start of the presentation, entitled Together we advance_gaming is scheduled for 23:00 Moscow time.
The presentation will be available for all those who wish to watch it on AMD official YouTube channel.AMD itself describes the upcoming event as follows: \"AMD executives will detail AMD's new high-performance and energy-efficient AMD RDNA 3 architecture, which will deliver a new level of performance, efficiency and functionality for gamers and content creators.
\"At the moment, very little is reliably known about the upcoming new products.
AMD showed the graphics chip Navi 3X back in August and already then it was known that the RDNA 3-based GPU will consist of several chips, by analogy with AMD CPUs.
This should reduce the cost, which would have a positive effect on the price of graphics cards.
At least, that should be so in theory.
Crystals GPU, or at least some of them will be made at 5nm process on the production facilities TSMC.Also earlier head of AMD Lisa Su (Lisa Su) said that the next generation graphics will provide 50% higher performance per watt of energy compared to current solutions, meaning Radeon RX 6000 on the RDNA 2 architecture.
Also AMD representatives said recently that they will not be getting a new (and potentially problematic) power connector with 12+4 pins.The latter is confirmed by recently leaked photo which seems to depict Radeon RX 7900 XT reference graphics card - it has a pair of 8-pin connectors.
Novelty is larger than the current flagship in the face of Radeon RX 6900 XT, but still not as huge as GeForce RTX 4090 graphics cards.
Note that AMD is rumored to be preparing several graphics cards on the flagship GPU next generation: Radeon RX 7900 XT and Radeon RX 7900 XTX.
They are rumored to offer up to 24 GB of GDDR6 memory and up to 12,288 stream processors.
Whether this is true we will find out in a few hours.

AMD announced the presentation of Radeon RX 7000 - RDNA 3 graphics will be presented on November 3

AMD has announced an online broadcast titled \"Together we advance_gaming\", which will be held on November 3 at 23:00 Moscow time.
This will be an online event dedicated to Radeon RX 7000 graphics cards based on RDNA 3 architecture, according to a press release that was published on AMD's official website.
AMD will unveil the new AMD high-performance and energy-efficient architecture RDNA 3, which will provide a new level of performance, efficiency and functionality for gamers and content creators,\" - noted in the press release.AMD graphics processors based on RDNA 3 architecture will be the first GPU company, consisting of several chips.
They will be manufactured at TSMC manufacturing facilities using 5-nm process technology.
AMD has demonstrated Navi 3x graphics processor (presumably Navi 31) back in August this year, but did not disclose any details about it.According to unofficial sources, AMD plans to introduce two Radeon RX 7000 graphics cards based on RDNA 3 this year, starting their sales in the second half of December.
AMD's graphics gas pedals are expected to get next-generation Infinity Cache buffer memory.
During a recent Ryzen 7000 processor presentation, AMD head Lisa Su said that the next-generation graphics will provide 50 percent more performance per watt of power consumption compared to current solutions, that is, compared to the Radeon RX 6000 based on the RDNA 2 architecture.
