Whether we like the situation or not, the fact is that Nvidia has significantly diversified the GeForce RTX 3000 model portfolio, but not much has changed at AMD. As the Radeons RX 6800/6900 came out in 2020, they are (or not) resold. However, the fact remains that the diversity of Nvidia’s offer is an effort to sell every GPU produced, rather than an effort to create a half-generation upgrade, which is not surprising given the current shortage. Each GeForce RTX 3000 model carries a unique GPU configuration, so each chip can be sold in the maximum possible configuration, whether it has a defect in one part or another.
According to leaker Greymon55, however, the AMD model offer is also likely to expand, the company is reportedly preparing a refresh of the RX 6000 series. Last year, it was rumored that AMD was preparing a 6nm version of the GPU. Navi 22 a Navi 23, which should first be deployed in notebooks and in 2023 serve for lower price relations as a supplement to chips Navi 31 / 32 / 33 (RDNA 3). But at CES AMD explicitly stated that the refresh of the mobile offer is built on 7nm versions Navi 22 a 23so how it is with the transition to 6nm process is not clear. It could be postponed or canceled (the company will not have 6nm of capacity left over when it produces central chiplets for Zen 4).
Some Radeon RX 6000 refresh is still going on. The mentioned leaker speculates that the core of these innovations could be the use of faster (18GHz?) Variants of GDDR6. These increase data throughput by 12.5% (which in itself does not mean 12.5% higher performance). The effect of memory (without changing the kernel configuration – whether in terms of clocks, TDP limits or numbers of functional units) would Navi 22 (Radeon RX 6700 XT) was not extreme, this kernel carries 96MB Infinity Cache, so the performance dependence on memory bus throughput will be low. It could be relatively higher for the GPU Navi 23 (Radeon RX 6600 XT), where the same number of ROP units accompanies 32MB Infinity Cache. There a faster memory could be known by some percentage more. For the sake of completeness, it can be added that versions of the Radeon RX 6900 XT with faster memories exist – they are used on the water-cooled version and higher OC models (18-18.5 GHz).
