June 8, AMD's RDNA architecture GPU has been developed for three generations, and last year's RX 7000 series used the latest RDNA3 architecture, claiming that the performance per watt has increased by 50%, but the final performance is difficult to explain.
The performance of the flagship RX 7900 XTX not only can not be compared with the RTX 4090 of the friends, but even the RTX 4080 can not be beaten, if the light chase is opened, the gap is even larger, and more than 50% of the performance is the norm.
FSR 3 technology, which is regarded as the killer, was originally the standard DLSS 3, but it has not been officially released, and the number of game support cannot be compared with N cards.
In addition to game performance, RDNA3 has no sense of presence in AI performance, energy efficiency is claimed to be greatly improved, 335W TDP power consumption is 95W lower than the 450W of RTX 4090, and the actual result has no advantages.
All in all, RDNA3 is good and powerful in theory,But compared with the RTX 40 series, it is really difficult to accept, N card is ridiculed expensive, but in addition to expensive, other advantages.
The hope of A rice can only be the next generation of RDNA4 architecture, that is, the RX 8000 series, according to the schedule should be released in 2024, the process upgrade of 3nm is unlikely, it should be a 5nm improved version of the 4nm process, but does not rule out AMD radical point on the 3nm process.
More importantly, RDNA4 design ideas will change, NVIDIA has successfully proved that light chasing AI is important, AMD has to follow,The new architecture will be greatly changed, the RT optical tracking unit will be reset, and the AI performance will be a highlight - after AMD's acquisition of Xilinx, there is no shortage of advanced AI technology and ecology.
RDNA4 will continue to use the small chip design of RDNA3, and the scale of computing core GCD and IO core MCD will be increased.Up to 144 CU units, full of 18,432 coresVideo memory can be up to 32GB, or 48GB, depending on the number of MCDS.
The RNDA4 has been scaled up by 50% and optimized to 3.5GHz,Theoretically double the performance,However, the figures in this regard are not very accurate, there are also at least 50% performance improvement, and 50% energy efficiency improvement to ensure that power consumption is not out of control.
If you remember the early Revelations of RDNA3 last year, you should understand that this RDNA4 is the full blood version of the original RNDA3, and you can only expect AMD to really make up its mind to engage in high-performance graphics.
In 2024, Nvidia will also launch the RTX 50 series, codenamed Blackwell, it is said that the performance will also be greatly improved, compared with the current 60% increase is not a problem, AMD RX 8000 hard just RTX 50 pressure is not small.
