Kernel work is much less tightly coupled than game engine work.

Consistent (but not universal) with my small number of observations, which is surprising because you'd think that low pay and lovely working conditions would attract the best.

I think you're judging it a bit harshly here, it's a GPU running at idle clocks versus Intel's second best GPU solution running all out. The 512SP solution @ 800Mhz has already shown it's equal to a Bonaire card running @ 1000Mhz, that's pretty loving astounding, I'm positive the 2700U is going to clown on all of Intel's GPU solutions. Like, for context, Bonaire or the M9 385X/R7 260X are about 15% faster than the RX 550, a desktop solution. It means core for core the Vega mobile solutions are considerably faster than the Polaris ones, which means IMHO the 2700U's iGPU will probably hit diminishing returns but come close to RX 460/R7 370 performance. Just imagine on desktop where you could clock them much, much higher. Really, I'm 100% getting the impression it's only Big Vega suffering from scaling issues and bottlenecking. EDIT:Seemingly same APU, GPU running @ 800Mhz http://ranker.sisoftware.net/show_run.php?q=c2ffcdf4d2b3d2efdbe8dbeadcebcdbf82b294f194a999bfccf1c9&l=en.

I want to believe that sub-48CU Vega doesn't suck. I want to believe that they can shove 12 CUs into an APU, underclock them a bit, and make a 65W budget gaming monster out of it. Everything we've seen though is that Vega's a compute card that happens to have some rasterizers attached to it, and that more than anything else scares me about the future of Radeon. I love my GTX 1070 to bits -- getting 1080p144 in FFXIV on max settings is a thing of beauty -- but I would not want an actual no poo poo DOJ-intriguing Nvidia monopoly.

Subjunctive posted:Kernel work is much less tightly coupled than game engine work.

ArgumentatumE.C.T. posted:Am I wrong in thinking that game programmers are frequently not the cream of their crop More so that a majority of programmers that aren't involved in games or OS level stuff don't really have to worry about multithreaded development, or when they do it's usually some problem thats almost always easily parallelizable. This is just an anecdotal observation from talking with other people that have graduated in the same class as me though. Having transitioned to game development, we have systems that have interconnected dependencies that are never ever simple as just chunking them into jobs, i.e. given newer gfx APIs we can generate draw calls in as many threads as we can all day long but we still need an explicit sync point to have a list of things we want to draw in the current frame. Games are still pretty serial in nature, which is why the job paradigm is so important. Whatever gameplay thing you're trying to accomplish still behaves in a serial fashion, but at least you can throw it into a job so the main thread can move on to the next thing. Of course now we have to worry about how important that job is; should it be done in this current frame? Is there another system that depends on that job finishing, thus requiring us to place a sync point in the main thread? Maybe we can use the deferred results on the next frame? By no means an expert on multicore programming, but I have my hands in restructuring/optimizing a game at the moment.

Keep in mind moving from 850Mhz to ~1200Mhz doubled the power consumption on Polaris 11. Early reports/rumors indicate Vega 10 XT running @ ~1200Mhz pulls some 200W and that adjusting voltage down at same clocks seems to yield tremendous results. I think Vega in the mobile space will work quiet well, maybe not to the extent hpnoe GPU's do but there is always that possibility especially since Vega can run in FP16.

bobfather posted:My overclocked i7-3770 non-K gets 41xx and 13xxx on Geekbench. Not that Threadripper isn't impressive - it totally is, but man the 3770 is almost 5 years old. That's with the processor underclocking itself to ~1.8ghz constantly during the benchmark, although I don't know if that hurts the score on geekbench. I was too lazy to reboot and turn it off in bios. It's kind of hard to not buy a ryzen 1700 for a fun home server build. That is really the sweet spot on the current generation of AMD processors it seems. It's also hard not to light dollars on fire for a 16 core threadripper.

Most of the big warehouse setups are in rural China, in places with dirt cheap electricity prices because power supplies had been overbuilt and the grid won't take the electricity out to bigger cities that need it (usually new hydro dam installations). The warehouses get tossed together in a few days with no safety considerations at all, so it's no surprise when they catch fire.

Horn posted:Up now quote:Due to the difference in memory latency between the two pairs of memory channels, AMD is implementing a ‘mode’ strategy for users to select depending on their workflow. The two modes are called Creator Mode (default), and Game Mode, and control two switches in order to adjust the performance of the system. It sounds simple enough so far, but AMD decided to make it more complicated than it ever needed to be.
