NVIDIA next-gen GPUs: Ampere on 7nm, Hopper on 5nm

Ampere will be using TSMC's 7nm node, while Hopper is rumored for Samsung's 5nm EUV process.

NVIDIA is expected to unveil its new Ampere GPU architecture during its GTC 2020 keynote, where it wants you to GET AMPED about it between now and especially on May 14, at 6AM PST.

We know that NVIDIA is one of TSMC's largest clients for its 7nm process node, while Samsung announced it was to begin production of its new 5nm (5LPE) EUV process in Q2 2020. Remember the mysterious 5nm chip NVIDIA was working on? Yeah, I would say it has something to do with that.

Samsung could be making NVIDIA's next-next-gen Hopper GPU on its new 5nm EUV node, with Ampere finding a home on the 7nm node by TSMC. We should expect NVIDIA to unveil its new GeForce RTX 3080 and RTX 3070 graphics cards sometime in August 2020, with a launch at Computex 2020 -- nothing is in concrete right now, but that seems like a viable launch window.

I've already written about rumors that NVIDIA's next-gen Ampere GPU architecture would be up to 75% faster than current-gen GPUs such as the Turing architecture, right after rumors that Ampere would offer 50% more performance at half the power of Turing. This is pretty crazy stuff right there.

Not only that, but we've got some rumored specs on the purported GeForce RTX 3080 and GeForce RTX 3070 graphics cards, which will both be powered by NVIDIA's new Ampere GPU architecture.

We've already heard that Ampere would offer 50% more performance at half the power of Turing, which sent the hairs on my neck standing up. Better yet, you can read about the leaked specs on the purported Ampere-based GeForce RTX 3080 and GeForce RTX 3070 right here.

GA103 (GeForce RTX 3080)

  • 10/20GB GDDR6
  • 320-bit memory interface
  • 60 SMs
  • 3480 CUDA cores

GA104 (GeForce RTX 3070)

  • 8/16GB GDDR6
  • 256-bit memory interface
  • 48 SMs
  • 3072 CUDA cores

AMD also just revealed its next-gen RDNA 2 / Navi 2X plans, something we referred to as Big Navi until just recently. Those specs are monstrous, but they pale in comparison to what NVIDIA has planned for its flagship HPC destined Ampere GA100 beast.

AMD RDNA 2 / Navi 2X / Big Navi Specs

  • 7nm node (confirmed)
  • RDNA 2 architecture (confirmed)
  • 80 compute units
  • 5120 stream processors
  • 17.5 TFLOPs compute performance
  • Hardware ray tracing support (confirmed)
