1. Preface: AMD's new generation RDNA 3 GPU has been waiting for 2 years

On Monday, December 12, two years after the release of the RDNA 2, AMD finally unveiled its new RX 7900 XT and RX 7900 XTX Gpus based on the RDNA 3 architecture.

In particular, the flagship RX 7900 XTX, priced at 7999 yuan, is 1,500 yuan cheaper than the RTX 4080, but its conventional performance is 5~6% ahead of its rivals. Both performance and price are directly against the weakness of NVIDIA.

However, due to various factors, we did not receive the graphics card until noon on the 12th, so we did not have time to do more comprehensive tests. This time with the RX 7900 XT review, to show you more data.

For this test, the Shaxun RX 7900 XT Darkdog is based on the Navi 31 chip. It has 84 CPU units and 5,376 stream processors. These parameters don't look much different from the RX 6950 XT.

But because RDNA 3 doesA stream processor unit with dual emission design. Each CU unit contains 64 FP32 units and 64 INT32 units. Each FP32 and INT32 unit can perform integer or floating-point operations on demand.

That is, when all FP/INT32 units do floating-point arithmetic, a set of CU units is equivalent to having 128 stream processors.

With 84 groups of CU, the RX 7900 XT is theoretically equivalent to up to 10,752 stream processors and has a floating point capability of up to 52TFLOPS, which is 2.3 times the RX 6950 XT.

In terms of price, the Shaxun RX 7900 XT Diablo follows AMD's MSRP at 7,499 yuan, while the RX 7900 XTX Diablo is 7,999 yuan.
