The performance is lower than expected, and the AMD RX 7900XT public card is exposed.
CTOnews.com, December 8, AMD announced a series of RX 7900 graphics cards based on RDNA 3 on November 3, in which AMD flagship graphics card RX 7900XTX public edition sells for 7999 yuan and sub-flagship graphics card RX 7900XT public edition sells for 7399 yuan.
The first GeekBench score of the RX 7900XTX public graphics card has been exposed, and it is surprising that its benchmark score is much lower than the figure released by AMD. The GeekBench score of the RX 7900XT public card is also exposed today, and its performance is also lower than expected.
CTOnews.com learned that the GeekBench running score showed that the RX 7900 XT scored 191822 in the OpenGL, 16% slower than the RX 7900 XTX. It has 5376 SP or 84 computing units (CU). This is 12.5% lower than the computing unit of the flagship product XTX. With such a performance difference, more users will choose XTX when the price difference is only 600 yuan.
The flagship model RX 7900 XTX has a 96CUJ 6144 stream processor, GPU frequency 1900-2500MHz, and single-precision performance up to 61TFLOPS.
