Two days before the launch of the GeForce RTX 4080 graphics card, AMD has decided to try and divert the attention of its potential customers and turn it towards its newly introduced Radeon RX 7900 series graphics cards based on the new RDNA 3 architecture.AMD noted the details, which should, in its opinion, should convince PC owners to opt for its gas pedals.Image source: AMDI AMD had already confirmed earlier that the main competitor of graphics cards Radeon RX 7900 XTX and RX 7900 XT will be just the model GeForce RTX 4080.Thus, the GeForce RTX 4090 will remain the fastest gaming graphics card, at least for the foreseeable future. Radeon RX 7900 XTX, RX 7900 XT and GeForce RTX 4080 specificationsThe Radeon RX 7900 XTX has a VRM power subsystem with 20 phases, three more than the GeForce RTX 4080 in the Founders Edition benchmark. The AMD Radeon RX 7900AMD graphics card board also draws attention to the fact that its new graphics cards are more compact than its competitor.They are shorter and thinner than the GeForce RTX 4080 Founders Edition.In addition, unlike GeForce RTX 40-series cards, Radeon RX 7900 XTX and RX 7900 XT gas pedals are equipped with DisplayPort 2.1 and USB Type-C connectors. AMD once again reminds that unlike the competitor its new graphics cards do not require any adapters and new power connectors.They are equipped with two regular 8-pin PCIe power connectors, making them fully compatible with most power supplies.It is also fair to say that in the $900-1200 price range AMD graphics cards will offer more video memory.The Radeon RX 7900 XTX gets 24GB of GDDR6 and the Radeon RX 7900 XT gets 20GB of GDDR6.The flagship GeForce RTX 4090 has 24 GB of faster GDDR6X memory on board, but its recommended price is $1600.The GeForce RTX 4080, on the other hand, has \"only\" 16 GB of GDDR6X at a recommended price of $1200. Unfortunately, neither AMD nor NVIDIA are yet ready to directly compare the performance of their gas pedals against each other.Since the GeForce RTX 4080 is not yet available, AMD is comparing its RDNA 3 architecture-based graphics cards against its own flagship Radeon RX 6950 XT gas pedal from last generation. Raster performance of the Radeon RX 7900 XTX and RX 7900 XTThe company has shared two graphics.According to them, the raster performance of new generation graphics cards in games when using 4K resolution is up to 67% higher than the Radeon RX 6950 XT, and the performance of the light tracing technology in the new graphics cards up to 82% higher than the Radeon flagship on the RDNA 2 architecture. Radeon RX 7900 XTX and RX 7900 XT ray tracing performanceTill the launch of Radeon RX 7900 XTX and Radeon RX 7900 XT are still a month away.Their release is scheduled for December 13.
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.
ASUS announced graphics cards Radeon RX 7900 XTX and RX 7900 XT in their own version TUF Gaming.The company is not ready to share the specs of new products, but the manufacturer has revealed some details about them.Image source: ASUSBoth gas pedals will get a massive cooling system, equipped with three fans.The thickness of video cards will be three expansion slots.Both will get a dual BIOS system with quiet and performance modes. Unlike the reference versions Radeon RX 7900 XTX and RX 7900 XT, variants from ASUS have got not two, but three 8-pin connectors of additional power.In addition, new items will be the first gaming cards from ASUS, which will support DisplayPort 2.1 interface. Graphics card Radeon RX 7900 XTX has a graphics processor with 12,288 stream processors, the reference gaming frequency is 2.3 GHz.The card has 24 GB of GDDR6 memory with 384-bit bus support.The Radeon RX 7900 XT model is based on a GPU with 10,752 cores and has a reference frequency of 2 GHz.This gas pedal has received 20 GB of memory GDDR6 with support for 320-bit bus.ASUS has not reported with what frequencies will run GPUs in its video cards.Also unknown is the price of announced Radeon RX 7900 XTX and RX 7900 XT TUF Gaming models.However, most of the prices for these graphics cards are close to the recommended ones, which are $999 and $899 respectively.The company only confirmed that the novelties will be on sale in December this year.
