According to the latest industry rumors, AMD will launch its new graphics cards Radeon RX 7800 and Radeon RX 7700 next month of September. Specifically, before this release takes place, it is expected AMD to announce both GPUs at Gamescomevent that will take place in Colonia del August 23 to 27. If the information is fulfilled, we would be just over a month away from officially knowing the new mid-high-range graphics cards from AMD.
Of these graphs, what could be their specifications are known, but for now there is nothing confirmed. These models would arrive based on the Navi 32 graphics chip, where, in the best of cases, we could find a configuration of up to 60 CUs, 3,840 Stream Processes, in the top-of-the-range model. This is not good news either, as the Radeon RX 6800 XT offers 4,608 Stream Processors. On the other hand, they are the same cores that the Radeon RX 6800 adds (not XT). In this way, despite the architecture change, as NVIDIA has done, do not expect a great leap in performance compared to the previous generation of GPUs.
Possible specifications of the AMD Radeon RX 7800
AMD Radeon RX 7800 we hope it makes use of a graphics chip Navi 32XT made by TSMC with their lithography N6. This chip would achieve a configuration of 3,840 Stream Processors. At the memory level, the already mandatory ones could not be missing 16GB of GDDR6 VRAM for a graph of this caliber.
This memory would arrive at a speed of 19.5Gbps which, together with a memory interface of 256 bitwould result in a bandwidth 624GB/sall with a TDP of 260W. 10W than its predecessor despite the use of a more efficient architecture, so the company will have had to resort to forcing an increase in frequencies to try to get some extra performance.
And the possible specifications of the AMD Radeon RX 7700
On the other hand, the AMD Radeon RX 7700 it would come with the graphics chip ship 32. From this it is speculated that it can arrive with a configuration between the 3,072 and 3,456 Stream Processors. For reference, the Radeon RX 6700 came with 2,304 Stream Processors, so in this specific case we will see a more noticeable performance improvement. Perhaps most interesting of all, is that this graph includes more memory than its predecessor. That is why it will go from 10 to more reasonable ones 12GB of GDDR6 VRAM. It must be remembered that 12 GB of VRAM is expected to be an almost mandatory requirement to play most of the 2023 titles, as long as you want to play activating the maximum graphic quality of the textures, of course.
In the case of the Radeon RX 7700, this 12 GB of memory runs at the same frequency of 19.5Gbps than the RX 7800, but we have a more limited memory interface than 192 bit. Despite this, you get a respectable bandwidth of 468GB/s of consuming 245W of energy. Here we already see a notable increase in consumption compared to the 175W of its predecessor, so here we can already see that a much more notable jump in performance is expected.
