While most of the focus here is understandably on the CPU side, there seems to be some interesting shifts taking place on the GPU side.
AMD currently has a process lead over Nvidia (and this is rumoured to be set to continue for a little while longer - apparently the first consumer Ampere chips are being fabbed on Samsung's inferior 8nm process due to lack of capacity at TSMC for the next few months)
Nvidia has clearly had an architecture advantage, although RDNA2 may close this gap, depending on how Ampere performs.
While Nvidia has had a much stronger showing in the GPGPU space, with CUDA helping it be the clear current winner, this also appears to have driven architecture decisions at Nvidia with the focus on tensor cores.
In gaming, Nvidia has put a lot of work into utilising these tensor cores for Deep Learning Super Sampling (DLSS). The idea being that you render at a lower resolution and then use deep learning to upscale in real-time to higher resolutions. DLSS 2.0 made some leaps in quality and DLSS 3.0 is on the horizon. It will be interesting to see:
a) How well they can get this working
b) Is AMD working on its own version of this?
c) If so, how well will the RDNA architecture be suited to this approach?
Will be interesting to watch how this plays out!
- theevilsharpie 6y ago> apparently the first consumer Ampere chips are being fabbed on Samsung's inferior 8nm process due to lack of capacity at TSMC for the next few months) I just wanted to clarify to anyone else that was initially confused, that the parent is referring to Nvidia's next-generation GPU architecture, not the ARM CPU developer.
- pjmlp 6y agoLets put it this way, Octane Render has dropped Vulkan support and replaced it with CUDA based Optix 7. https://home.otoy.com/render/octane-render/ https://home.otoy.com/render/octane-render/ So how is AMD going to get relevant in the Hollywood and TV studios that are the big buyers of OctaneRender?
- Arelius 6y agoI wasn't aware that OctaneRender was actually a large portion of the Hollywood and TV studio segment.
- shaklee3 6y agoWhat's your source? Ampere are shipping. AMD has no fab advantage since they have no 7nm enterprise cards. Their entire enterprise line has been somewhat of a joke to date .
- galeos 6y agoYou are correct, the enterprise Ampere A100 is on the TSMC 7nm process. I should have been clearer that I was referring to the consumer Ampere GeForce cards due later this year. The 8nm rumors have been widely reported[1] but at this point are just that, rumours.
