Samsung is ready with a GDDR7 memory chip rated at an oddly-specific 28 Gbps. This speed aligns with the reported default memory speeds of next-generation NVIDIA GeForce RTX "Blackwell" GPUs. The Samsung GDDR7 memory chip bearing model number K4VAF325ZC-SC28, pictured below, ticks at 3500 MHz, yielding 28 Gbps (GDDR7-effective) memory speeds, and comes with a density of 16 Gbit (2 GB). This isn't Samsung's only GDDR7 chip at launch, the company also has a 32 Gbps high performance part that it built in hopes that certain high-end SKUs or professional graphics cards may implement it. The 32 Gbps GDDR7 chip, bearing the chip model number K4VAF325ZC-SC32, offers the same 16 Gbit density, but at a higher 4000 MHz clock. The Samsung website part-identification pages for both chips say that the parts are sampling to customers, which is usually just before it enters mass-production, and is marked "shipping."

4GB (or 32Gb (gigabit)) chips are what is needed. 16GB of VRAM wasn't cutting it in 2022 forget about 2024. No, there are plenty of games that use the full 16GB or more than none of the YouTube channels we watch test, ever.

"Use" as in it's reported as allocated, or "use" as cards with less than 16 GB suddenly fall behind lower tier cards with more memory, develop stutters etc.?

I think for many, the current 24GB cards are hard to fill. All 32GB would do is give headroom for some AI thing that didn't fit into 24?
But, for the AI content that did fit into 24, the memory bandwidth itself is the benefit. Excited to see what the first GDDR7 GPUs bring to the table either way.

Both? Depends heavely on the game and card but when it makes a difference it's very noticeable. The 4060 16gb review here on TPU shows basically no difference other than in last of us but if you look at other sites there's mentions of 40% when enabling RT which like or not will be ever more present.
