A remarkable amount of details have emerged about Nvidia’s upcoming Ampere GPU series. Twitter user KittyCorgi posted unconfirmed Specs for the next-gen GeForce RTX 3070 and RTX 3080 cards, evidently corroborated by information sourced by Chinese outlet MyDriver.
The new leaks are plausible and even come with full block diagrams. What exactly are we looking at, though, with the NVIDIA RTX 3080 and RTX 3070? The Taipei Times had recently made the bold claim that upcoming Ampere GPUs will be as much as 50 percent faster than Turing, while also being 50 percent more power-efficient (thanks to the 7nm node).
The leaked specs, if combined with assumptions on IPC improvements and higher clock speeds thanks to the 7nm EUV process node, put RTX 3070 and RTX 3080 performance roughly in that ballpark.
The RTX 3070 is allegedly based on a full GA104 GPU—the high-end part traditionally reserved by Nvidia for its x80 lineup. It will feature 48 SMS, and 3072 CUDA cores. The GeForce RTX 3070 will either feature 8 GB or 16 GB of 16 GHz GDDR6 VRAM over a 256-bit bus for 512 GB/s of bandwidth. A 50 percent performance increase over the RTX 2070 isn’t inconceivable, considering the large increase to shaders as well as higher bandwidth, higher clocks, and improved IPC.
The RTX 3080 is a further step up. The leaked specs suggest that this will be a part with 3840 shader cores and 60 SMs, a considerable increase over the RTX 2080. It’s set to feature either 10 GB or 20 GB of 16 GHz VRAM, across a 320-bit bus for a remarkable 640 GB/S of bandwidth. If these specs are accurate, this would, in relative terms, the largest x80 GPU Nvidia’s released, with a shader count comparable to the 1080 Ti, and not far behind the RTX 2080 Ti.
Lastly, please keep in mind that these are rumors and unconfirmed reports. It might all turn out to be a hoax, so take it with a grain of salt. NVIDIA is rumored to launch the first wave of Ampere cards at GTC 2020, in March. However, I expect it to be more of an architectural reveal, rather than a product launch.
We expect to hear more about Ampere in the months to come. Between these parts and AMD’s impending Big Navi announcement, 2020 is shaping up to be a big year for PC graphics.
