AMD has at all times taken totally different approaches to fixing reminiscence administration points in graphics architectures. Reminiscence bus width and VRAM capability have typically at all times been excessive, however in fact they weren’t sufficient for efficiency. The pink staff proved to vary the principles of the sport with the Infinity Cache expertise we heard with RDNA 2. Due to this caching expertise, GPUs with a comparatively low 256-bit reminiscence interface have change into aggressive with high-end 384-bit NVIDIA playing cards.

With the NVIDIA “Ada Lovelace” and AMD “RDNA 3” graphics architectures, the competitors between the corporate appears to get even hotter. Greymon55In response to , AMD’s new flagship GPU, Navi 31, may have a 384-bit vast reminiscence interface as a substitute of 256-bit. Its sibling, Navi 32, shall be launched with a 256-bit reminiscence subsystem, not 192-bit. Navi 33, which shall be used on lower-end playing cards, will retain the 128-bit (288 GB/s) bus.

Assuming every of those playing cards has at the very least 18 Gbps of GDDR6 reminiscence, the Navi 31 may have at the very least 864 GB/s theoretical bandwidth. Furthermore, if we exclude Infinity Cache. Additionally, new playing cards usually tend to include 20Gbps reminiscence. Working with 20 Gbps GDDR6 reminiscence chips, a Navi 31 GPU (maybe the RX 7900 XT) can improve bandwidth to 960 GB/s, an enormous 87.5 p.c improve over the present RX 6900 XT. As well as, high-end playing cards are very prone to supply 24 GB of reminiscence capability.

We have now already reported that the inexperienced staff will make important improvements on the cache facet with the RTX 40 sequence “Ada” graphics playing cards. Consequently, severe research are being carried out on reminiscence on either side. Competitors within the GPU market shall be fierce once more this yr and we sit up for the following technology playing cards.

Fatih, who has been intertwined with expertise and video games from a younger age, is completely happy to conduct analysis and convey his experiences to folks.
