5070 vs 4070: Same lame planned obsolescence 12 GB VRAM (it doesn't matter if it's GDDR6X or GDDR7, once u run out of VRAM, u run out of VRAM) and +25% increased TDP/TGP. According to NV's own graphs, the "RT" (not the other ones where "DLSS" is added) performance increased by like 20-30% (looking by eye, not counting the pixels). So the power efficiency performance increase looks very low indeed (not unexpected because almost the same manufacturing process is used).
5070 with only 12GB VRAM is a big disappointment. At least give us a 24GB clamshell design (like you did for the 4060 Ti 16GB (NV, did you get too much scared of your 8GB planned obsolescence? *wink*) for people who want to run LLMs.
5070 Ti vs 4070 Ti: Increased the VRAM from 12GB to 16GB (NV got too much scared of their planned obsolescence). Judging by this, a 6070 non-Ti is going to have 16GB. Of course, a switch to 3GB GDDR7 modules next year for their refresh cards would be nice. A 32GB VRAM clamshell version of the 5070 Ti would also be nice, 24GB are slowly becoming not enough (for LLM stuff).
5090: I give NV credit for offering a 512bit 32GB VRAM GeForce card, which many people may use instead of the more expensive RTX 5000 Ada workstation card (256bit GDDR6, clamshell, 576 GiB/s) (for tasks where workstation card features are not required), which is twice as expensive.
The "AI TOPS", of say the 5070, looks to be 988 INT4, instead of 4070's 466 INT8. 988 INT4 / 2 = 494 INT8, 494 INT8 [5070] / 466 INT8 [4070] = 1.06 -> 6% improvement, which reminds me of
these 6%.
Having a 4070, so far it looks like I'm going to sit this one out and see if NV switches to 3GB GDDR7 modules for their GeForce 50 refresh cards next year (although clamshelling/doubling the VRAM this year for certain cards would be even nicer, but that would double the VRAM and it wouldn't be NV if they'd only switched to 3GB modules only next year and only 1.5x the VRAM). The 4070 with its 12GB
runs out of VRAM when enabling even the Medium Path Tracing (Full Ray Tracing) setting in Indiana Jones and the Great Circle.
