https://rocm-documentation.readthedocs.io/en/latest/Programm... "HIP is designed to ease the porting of existing CUDA code into the HIP environment." Not even close an drop-in swappable alternative.
Of course not, and some things would never be ported. But if they had a massive cost advantage for a year or two in data centers, a lot of things would get ported, quickly.
AMD's rather old Radeon VII can really smash a 2080 Ti if you're doing relatively simple streaming computation, like say video processing. That 1TB/s HBM is no joke, and there's 16GB of it, at ~half the price of the 2080 Ti with 11GB. Nvidia's memory compression is very impressive and allows them to do better with a narrower memory bus in many situations (such as games), however if your data is not so compressible (o…
Did you manage to achieve 1TB/s? https://www.sisoftware.co.uk/2019/08/01/amd-vega2-gpgpu/ BW test over there shows 627GB/s of actual BW.
I got 704 GB/s on my machine[1] using their test.

I recently purchased a laptop with an Nvidia/Intel composite setup. As a Linux user, I’ll never buy a laptop with an Nvidia GPU again (if I can help it). What a pain. A nice piece of hardware with relatively pathetic software to drive it.
Nvidia has traditionally been very easy to use with Linux, as long as you were ok using their non-free drivers. Why was it so problematic for you?
AMD cards also work with hackintosh builds. Some of the cards work seamlessly, others take minor config, but much better than the nVidia support these days.

The ATI brand hasn't been in use for something like a decade.
Same technology and same ship being run by the same people. Why patronize a rebrand if nothing has changed?
Not true. They're gone as of a year or two ago. Ironically, they're at Intel.
The big problem right now is that ROCm, AMD's equivalent to Cuda for deep learning, is not supported for the consumer Radeon Navi cards. I had hoped it would be supported in ROCm 3.0 when that was released - but there has been no official word, which is worrying. If AMD are to compete in the GPU/DeepLearning space, it will be because they have hardware that is competitive (not even as good as Nvidia), low cost, and d…
I agree that the lack of (official) Navi support is just bad strategy on AMD's part, but I disagree with your numbers. Their goal needs to be performance parity or dominance, and then perhaps offer a slight discount. That's how they're succeeding with Zen on CPUs. Offering the kind of steep discount you write about is just bad business.
They necessarily have to sell at a huge discount or datacenter providers won’t even pick up the phone when they call.

The NVidia Optimus switchable cards are not well supported on Linux. On desktop NVidia is good. On laptops I like Intel graphics. because I don't want to muck around with getting working drivers.
I agree. On laptops I usually have an nVidia hybrid GPU but I always switch it off as I don't need it and use only the embedded Intel GPU. Actually getting the nVidia GPU "really" switched off has often been a bit of a challenge. Currently on a Lenovo P71 what I do is to have the nVidia-module not loaded (blacklisted or not even installed), load the "bbswitch" module and then execute "tee /proc/acpi/bbswitch <<<OFF"…
NVidia on desktop "works" for me, but suspend/resume is a fiasco - one cycle and the graphics are never right again, flickering and crap everywhere.

Nouveau ought to turn the card off automatically, if loaded. It might not be able to do anything else, but it should at least do that. NVidia on desktop "works" for me, but suspend/resume is a fiasco - one cycle and the graphics are never right again, flickering and crap everywhere.
Thx - I never even took into consideration Nouveau.
Sorry, I have 0 experience with desktop & suspend (I have 2 desktops, both of them using nVidia, but they're basically servers running databases so I have never made them go to sleep).

It's not comparable in efficiency but AMD is already shipping Vega II modules in the Mac Pro that claim "up to 28.3 FP32 TFLOPS". And regardless, the article is about 4K gaming. I don't doubt Nvidia will have some 7nm monster but there might be a time period before it launches where AMD briefly regains the crown.
That's not equivalent. That's a card with two ASICs on it, with each being 14TFLOPS. It's identical to the V100, but 2-3 years later.

Nvidia doesn't make any cards with two ASICs on it. There is no equivalent.
