After PowerColor spilled the beans on the RX 7800 XT, it’s now ASRock’s flip. AMD’s companion, by way of its EEC registrations, signifies the reminiscence configuration of its future RX 7700 XT and RX 7800 XT.
RX 7700 XT: 12 GB 192-bit reminiscence!
Let’s begin with the little RX 7700 XT, which, in response to EEC registrations, ought to boast 12 GB of reminiscence. For this quantity of VRAM, there’s no alternative however to go for a 192-bit bus. Coupled with reminiscence operating at 19.2 Gbps, this provides us a complete bandwidth of 468 GB/s.
In precise truth, the reminiscence configuration of this card is similar to that of the RTX 4070, each by way of capability and throughput. Remember that NVIDIA’s 4070 additionally gives 12 GB of reminiscence on a 192-bit bus. However, the chameleon’s VRAM is quicker: 21 Gbps, which allows larger bandwidth: 504.2 GB/s.
RX 7800 XT: 16 GB of 256-bit reminiscence – however we knew it!
As for the RX 7800 XT, it’s clear that we’re transferring up a gear, with 4 GB extra reminiscence. The similar goes for bus width, which will increase to 256 bits. Once once more, coupled with reminiscence operating at 19.5 Gbps, this provides a reminiscence bandwidth of 624 GB/s.
Compared with the NVIDIA vary, this 7800 XT would provide a reminiscence configuration much like that of the RTX 4080. The GeForce, whereas providing 16 GB of 256-bit GDDR6, gives a better reminiscence bandwidth: 716.8 GB/s, due to its quicker reminiscence.
Once once more, it stays to be seen what these new AMD playing cards will ship by way of efficiency. However, we are able to see the RX 7700 XT competing with the RTX 4060 Ti and the 7800 XT taking part in elbows with the RTX 4070. In any case, on the reminiscence entrance, the AMD playing cards are extra fascinating and may have much less bother with VRAM-hungry video games like Resident Evil 4 Remake.
