AMD announces Radeon RX 7900 XTX and 7900 XT graphics cards at $999 and $899 – AMD

At the Together We Advance Games event, AMD CEO Dr. Lisa Su announced the company’s new Radeon RX 7000 series of graphics cards, which are based on the RDNA 3 architecture with the ultimate goal of dominating the performance/watt segment in all price categories.

The company’s new GPUs are the world’s first to use a more than one-chip package connected by the well-known and impressive high-bandwidth Infinity Fabric and paired with up to 24GB of GDDR6 memory.

With a 5nm fabrication method, 61 TFLOP in terms of computing performance, 5.3 TB/s bandwidth and 58 billion transistors, the new RDNA 3 architecture chipset introduces, as Dr. Lisa Sue, amazing gaming performance. In terms of performance / watts increases by up to 54% compared to the last generation of RDNA 2.

The AMD CEO then announced its first two RDNA 3 graphics cards, the Radeon RX 7900 XTX and Radeon RX 7900 XT with 24GB and 20GB of GDDR6 memory, respectively.

Both graphics cards are based on the Navi 31 GPU, the first multi-chip client graphics processing unit (MCM) for gaming. More specifically, Navi 31 as the GPU codename is MCM with seven logical blocks totaling 58 billion transistors and no HBM (High Bandwidth Memory) stacks, unlike in the past.

Now, the package includes a large GCD (300 mm²) fabricated at 5 nm and six MCD (6 x 37 mm²) fabricated at 6 nm with an Infinity Fabric hyperlink that handles the ‘connection’ between them. Each MCD includes 16MB of Infinity Cache and a 64-bit bus. In total, the GDDR6 memory input / output width is 384 bits.

The GPU of the Radeon RX 7900 XTX has 96 controllers while in the case of the Radeon RX 7900 XT there are 84 controllers. In the case of the XTX version we have 24 GB of GDDR6 memory and 384-bit memory bandwidth while in the case of the XT we have 20 GB of GDDR6 memory and 320-bit memory bandwidth. The total panel power (TBP) is 355W and 300W, respectively.

The company also announced the Radiance Display Engine, thanks to which it provides support for the DisplayPort 2.1 standard and thus resolutions up to 4K at 480Hz or even 8K at 165Hz with a single cable. The new dual media engine also provides support for simultaneous AVC/HEVC encoding/decoding, 8K60 AV1 Encode and Decode, etc. According to AMD, the Radeon RX 7900 XTX offers up to 70% higher performance compared to the Radeon RX 6950 XT.
