Where before there was a floating point path and an integer path, there is now a dedicated FP32 path and one that can either operate as floating point or integer, effectively doubling the FP32 resources if necessary. That's because Nvidia has redesigned its streaming multiprocessors (SMs) to include double the number of floating point (FP32) units as previous GeForce GPUs. The GA104 silicon at the heart of the RTX 3070 comes with 5,888 CUDA cores, which looks like a hell of a lot of gaming logic, especially next to the ol' RTX 2080 Ti and its 4,352 CUDA cores. the green team has not only focused on boosting the ray tracing performance of its 2nd gen RT Cores, but it's also made improved rasterised gaming performance central to its new GPUs. We've covered it in-depth in our Nvidia RTX 3080 review, but once more with feeling. The Nvidia Ampere GPU architecture is very much a known quantity now. (Image credit: Future) Nvidia RTX 3070 specs The notion is that demand has far outstripped what the green team expected, though it does speak to a GPU market desperate for new cards that deliver a generational performance leap which makes the previous gen chips feel oh so old. We still don't know what the real story is right now Nvidia tells us that supply has been along the same lines as the GeForce 10 and 20-series cards, but we haven't been able to gather specific numbers to speak to that assertion. Indeed Nvidia even delayed the launch of the RTX 3070 specifically to try and ensure more stock is in the channel on release to try and placate the unprecedented number of people after new graphics cards.
Supply and demand have been key factors in GPU discourse following the launch and subsequent utter absence of both the RTX 3080 and RTX 3090 cards, to the point where AMD is seemingly now making it a point of its next-gen marketing.
Which ought to make it a very desirable card… and you probably know where I'm going with this.
