AMD had better integer performance. That's why they got it; their hardware was much better suited for bitcoin hashing. My 6870s paid for themselves. And the rest of the computer.

A thing needed to do mining (IIRC some sort of bit shifting) takes 1 clock cycle on radeon cards, but 3 cycles on nvidia cards, so clock for clock amd gpus were 3 times as fast. And, if you underclocked the rams, the cards GPU could often be pushed quite high, too. I think 750Ti fixed that, but it was too little too late (290 was still way faster simply due to more pipes), and nothing was mined on GPUs by the time bigger maxwells appeared.

Multi-GPU is definitely AMD's plan for the future. Whether it all works out who knows but here's Raja Koduri talking about it: https://youtu.be/4qJj1ViyyPY?t=246

Don Lapre posted:290's were selling for like $1k, no way it was due to price. Yeah nobody who wanted a 290 for gaming really got one for 6 months after release lol. 1k was at its worst but it was consistently 700+ for a long time. For the fanboy driven market share talk ive spoken my mind on this plenty but, well, Polaris better be the poo poo. $300-$400 for 980ti performance as per the earlier posts is absolutely expected and shouldn't be surprising, I'd hope for slightly better than that (as this is already expected of Pascal as well). What they really need to do is release on a more aggressive timetable from what I've seen so far. Of course by now they can't release any earlier than they possibly can, but... it needs to happen. The lack of response to the 900 series was worrisome, the 300 series "release" was turning into a writing on the wall situation, the Furies did not help anything at all. The last card of note was released in 2013. If DX12 rolled out a year earlier it would have helped them a lot more but considering how close we are to the next gen that may become somewhat moot, at best it will be a "heh sorry you bought a 980ti since everything runs DX12 now" in the future. If Pascal does poorly with DX12 though that would be a huge deal, but it'd be dumb to hope that one brand does poorly with some feature to benefit the other side. It's already bugging the poo poo out of me that nvidia may get the first set of cards out, especially since its apparent its going to be popular ones. AMD (rightly so - sorry) lost a bunch of customers, and the only way to get most of them back is to bring something not just competitive, but better.

Nvidia will have practically no mobile SKUs until 2017 though, and AMD and Nvidia are both targeting completely different market areas this year, and compute and mobile are both fairly high revenue, adjusting for margins. I think the situation is somewhat less hosed than people are expecting. AMD just needs Zen to hit third base, really.

I'll seriously entertain buying a $300-350 Polaris if it lives up to the rumors, but the reservations will come from the fact that AMD's still sorely lacking on driver frequency and reliability. Sure, nVidia fucks up drivers as well, but thanks to leaks and alternate versions (like iCafe drivers), if one driver doesn't work, you've got about *20* you can try until you get a stable result. A $300-350 card that delivers 980Ti numbers without stable/reliable drivers is like having a dragster with a loose wheel.

I just want to see 960M levels of performance for around 30 watts or 970M levels for 40W which would make it feasible to have dGPUs in more ultrabook size machines.

Seems like the speculation has been all over the place Oh I dont know what they will actually deliver, I mean in general it would be a stretch for me to imagine two gens in a row that delivered the previous one's flagship performance at 1/2 the cost. But it is a die shrink so its feasible (so im told anyway) and I'd say that people are outright expecting 980ti performance at $300-$400, perhaps without any great reason. Although the 10-15% number is a little suspicious since that happens to be the common way to describe the 980's performance over the 970 and, if you assumed based on expectation that the 1070 will perform on par with a 980ti you could then say "the 1080 will only perform 10-15% better than the 980ti", much like you could say the 980 only performs 10-15% better than the 780ti since the 970 is regarded as being on par with the 780ti. I'm not saying thats where that comes from, it just seems a little convenient.

A $300-350 card that delivers 980Ti numbers without stable/reliable drivers is like having a dragster with a loose wheel. So I'm pretty sure that right now NV's drivers are crashing in multiple DX 12 games, judging by the OC3D review of the latest AMD drivers, where they couldn't get numbers for the 980 Ti in DX 12 for Hitman and Quantum Break's issues. ~*NVIDIA quality drivers*~ Don't forget the 364 drivers, and I'm pretty sure there was another bunch pretty recently. I mean sure it's not hard to do due diligence, but I wouldn't go saying that NV drivers have been anything but lacking of late.

Come on Pascal and Polaris, I want to upgrade from this old 660Ti and i5-2500K.  I want to build a Skylake rig with a Pascal or Polaris GPU whichever one is a better deal unless they're both great then I'll just stick with Nvidia and get a Pascal card. And speaking of which I finally installed Windows 10 on my machine (a clean install) and I'm having really strange issues with my ASUS 660Ti even with the newest drivers. The card will get stuck in low power mode and my games run like rear end until I do a reboot or the card gets stuck in high performance mode but doesn't want to engage the boost clock meaning it won't engage my overclock until I reboot. spasticColon fucked around with this message at 23:13 on Apr 26, 2016 |

I bought the 2500k the first day I could and at this point I think I've used it longer than any other single piece of computer gear ever. Been solid across two motherboards and cases and a ton of other peripherals, gonna be driving VR in a few weeks for me too. That is kind of depressing to think about really, maybe the often (wrongly) predicted death of x86 is finally upon us.

Well Skylake does offer noticeably better performance because of DDR4 right? And besides my motherboard is 5 years old and if it craps out do they even make decent Sandy Bridge motherboards anymore?

What type of interpolation do modern gpus do when scaling to a lower resolution? Bilinear? Bicubic? E: also does scaling from the gpu add any display lag to the pipeline?

It's like it's incredibly hard extracting more instruction level parallelism from current superscalar out of order architectures. It's why Apple's CPU core looks a lot like Intel's and I wouldn't be surprised if AMD's looked like both.

spasticColon posted:Well Skylake does offer noticeably better performance because of DDR4 right?

This includes both AMD APUs and Skylake - moving to faster memory or DDR4 (for Skylake) can make a ~25% difference in performance IIRC. This doesn't apply to CPU performance, but iGPU performance is basically limited by the fact that you can't cram enough bandwidth through DDR3 or DDR4 for any meaninful performance. Same as for DDR3 dGPUs. ItBurns posted:Which games? FO4 is another, it also seems to scale noticeably from Skylake IPC improvements even in CPU performance although I think some of this is also related to DDR4 vs DDR3 on the earlier chips. quote:i5-4690K with Titan X, min/avg fps: Another:  http://www.techspot.com/review/1089-fallout-4-benchmarks/page6.html Paul MaudDib fucked around with this message at 01:43 on Apr 27, 2016 |

I'm more amazed that the 8350 seems unfazed at the grossly underclocked RAM. Edit: quote:Yes, we know there's a significant difference between the now obsolete 1333MHz memory speed and 2400MHz, but from memory I don't recall it having anything like that kind of impact on gaming performance. Interestingly the same variation in memory speeds had little impact on the AMD FX-8350's performance, as the processor was just 13% faster with the quicker memory. I guess I'm not the only one.
