NVIDIA Ampere NVCache to speed up load times

We already heard rumors earlier this year about NVIDIA's Ampere architecture featuring NVCache but now there's some fresh information at TweakTown. The site writes the feature looks a bit like AMD's High Bandwidth Cache Controller (HBCC) that made its debut with the Vega architecture. NVCache will reportedly make dynamic use of the video card memory, your system memory, and your SSD to shorten game load times. Next, there's also a rumor that NVIDIA found a way to leverage the Tensor Cores on its Ampere GPUs to speed up the compression and decompression of data stored in the video memory.
Well, back in the May leaks about Ampere and NVCache we heard that it "leverages both your DDR & SSD for enhanced load times & VRAM". The new leaks from Moore's Law is Dead tease that NVIDIA's upcoming NVCache on Ampere cards in the GeForce RTX 3000 series family will "dynamically utilize bandwidth from SSDs, VRAM, and DDR for multiple tasks at the same time".

There's also Tensor Memory Compression that on Ampere, and will reportedly use Tensor Cores to both compress and decompress items that are stored in VRAM. This could see a 20-40% reduction in VRAM usage, or more VRAM usage with higher textures in next-gen games and Tensor Memory Compression decreasing that VRAM footprint by 20-40%.
NVIDIA's Ampere desktop GPUs are expected to be introduced in September.
