NVIDIA GeForce RTX 40 Series GPUs are getting a massive upgrade in the L2 cache department, according to the latest data derived from the cyber attack on green team.

The AD102 GPU, which will presumably power next-generation flagship graphics cards such as the GeForce RTX 4080/4090, will feature up to 96 MB of L2 cache, a huge increase over the GA102’s (e.g., GeForce RTX 3080/3090) 6 MB of L2 cache.

Some believe this could be NVIDIA’s own version of AMD’s Infinity Cache, which red team implemented for its Radeon RX 6000 Series graphics cards as an effective way of boosting memory bandwidth while keeping to a smaller memory bus.

  • The data supposedly confirms that “Ada” GPUs would have 16MB of cache per 64-bit memory bus, significantly more than Ampere with 512 KB per 32-bit memory.
  • It is said that [AD102] would have a die size of 600 mm², about just as big as GA102.
  • The RTX 40 GPUs will be getting up to 71% more cores than RTX 30 GPUs, but that’s assuming each chip will see its full implementation released to the market.
