Truth seekers, avec le gros nick frost. Une série horreur vite fait/comedie au format court, les deux premiers ep sont pas ouf mais le reste est bien mieux.

TETRIS® EFFECT: CONNECTED adds an all-new robust multiplayer expansion to the huge variety of addictive and innovative single-player modes that Tetris Effect is known for. Connect and play with or against each other in all-new modes like “Zone Battle,” which shakes up traditional 1-on-1 Tetris gameplay via the time-stopping Zone mechanic, or try the innovative co-op of “Connected” mode, where up to three players can literally connect their Tetris playfields together and play as one, as they work together to take down a series of increasingly-challenging CPU-controlled bosses.

Will AMD GPUs + ROCm ever catch up with NVIDIA GPUs + CUDA?

Not in the next 1-2 years. It is a three-way problem: Tensor Cores, software, and community.

AMD GPUs are great in terms of pure silicon: Great FP16 performance, great memory bandwidth. However, their lack of Tensor Cores or the equivalent makes their deep learning performance poor compared to NVIDIA GPUs. Packed low-precision math does not cut it. Without this hardware feature, AMD GPUs will never be competitive. Rumors show that some data center card with Tensor Core equivalent is planned for 2020, but no new data emerged since then. Just having data center cards with a Tensor Core equivalent would also mean that few would be able to afford such AMD GPUs, which would give NVIDIA a competitive advantage.

Let’s say AMD introduces a Tensor-Core-like-hardware feature in the future. Then many people would say, “But there is no software that works for AMD GPUs! How am I supposed to use them?” This is mostly a misconception. The AMD software via ROCm has come to a long way, and support via PyTorch is excellent. While I have not seen many experience reports for AMD GPUs + PyTorch, all the software features are integrated. It seems, if you pick any network, you will be just fine running it on AMD GPUs. So here AMD has come a long way, and this issue is more or less solved.

However, if you solve software and the lack of Tensor Cores, AMD still has a problem: the lack of community. If you have a problem with NVIDIA GPUs, you can Google the problem and find a solution. That builds a lot of trust in NVIDIA GPUs. You have the infrastructure that makes using NVIDIA GPUs easy (any deep learning framework works, any scientific problem is well supported). You have the hacks and tricks that make usage of NVIDIA GPUs a breeze (e.g., apex). You can find experts on NVIDIA GPUs and programming around every other corner while I knew much less AMD GPU experts.

In the community aspect, AMD is a bit like Julia vs Python. Julia has a lot of potential, and many would say, and rightly so, that it is the superior programming language for scientific computing. Yet, Julia is barely used compared to Python. This is because the Python community is very strong. Numpy, SciPy, Pandas are powerful software packages that a large number of people congregate around. This is very similar to the NVIDIA vs AMD issue.

Thus, it is likely that AMD will not catch up until Tensor Core equivalent is introduced (1/2 to 1 year?) and a strong community is built around ROCm (2 years?). AMD will always snatch a part of the market share in specific subgroups (e.g., cryptocurrency mining, data centers). Still, in deep learning, NVIDIA will likely keep its monopoly for at least a couple more years.

Même pour un commentateur caustique des extravagances dérisoires de notre époque avisé comme moi ce gouvernement aura décidément réussi à me surprendre jour après jour.
