Someone asked ASUS to send them nudes. Joke request, but interesting photo response. Left is an AMD mobo, right side is an Intel.

You mean the part where it says "32nm Vishera 95W" right in the middle wasn't warning enough?

No difference in Blender. That is odd. Even if every thread is completely self-contained without any crosstalk between complexes, you'd think that they would still gain from the increased memory clock.

Except you can't even run it a thousand times, because _the benchmarks get better over time_ because of the branch prediction learning thing.

No, just AM5. AM4's going to be re-used until 2020, remember? Actually, I have serious doubts that DDR5 will actually addreess anything either, CAS latency numbers keep ballooning, and I don't remember if DDR5 was doing anything to address that.

Paul basically stole my thunder and made every point for me. I've put out some feelers and asked if Wendell and/or Ryan can do benchmarks with different CAS latencies as the variable and then to see if a significant correlation between tighter CL and benchmarks exists.

And we're saying, that only holds true in cases where the processor is Intel, because cases where an AMD processor are worthless. It's why memory profiles are all tuned to Intel chips, because they were the only thing that was worth running. Because of how the Infinity Fabric and memory controller are handcuffed to eachother, it stands to reason that there may exist a case where modern Zen-based processors running at a lower CL value display disproportionately better performance relative to any other knob that can be turned. And that paper was written in 2015. All these articles and tests from before this year have an implicit "But this really only applies to Intel parts because of how lovely and irrelevent Bulldozer is."

I don't know if I think CL value affects the speed of the fabric, but instead of saying "it doesn't, here are things proving that point that were run on Intel parts" I'm saying, "Well, time to find out if this holds true for Zen too!"

So CL value has an inverse correlation with fabric speed, which in turn has negative effects on overall performance, but they're improving memory latency by up to 6ns with BIOS updates using the latest AGESA? Maybe I am an idiot that needs to stop posting at 2 AM and go the gently caress to sleep, but something doesn't add up.

So, apparently the Bayonetta PC port is utterly unplayable on AMD CPUs right now? And not just Ryzen, everything going back to early Bulldozer is unplayable, or so I hear. :hmm:

1500X or 1600, I'm not decided yet. 1600X not a big enough step up over the 1600 on the price/perf scale to warrant the stretch, imo. Something around the $800 mark per box, when all is said and done.

Obsurveyor posted:What's up with memory prices anyway? The same stuff I bought 6 months ago is 55% more expensive today and prices in general seem up from then. Thinking I should just pull 32GB out of my machine and use it on the new one, rather than drop up to $175 on freaking 16GB. Toshiba tried to get into nuclear energy and failed. The Westinghouse subsidiary filed for bankruptcy protection, but it has severely injured the parent company itself. Their DRAM and NAND businesses are likely to be sold off to its competitors. Combined with the usual demand outstripping supply, you can expect it to get even worse in the fall. SwissArmyDruid fucked around with this message at 19:19 on Apr 14, 2017 |

I couldn't have predicted how badly the Westinghouse bankruptcy affected Toshiba, but really, they overpayed like hell for it. Solar's most recent surge just absolutely put a stake into nuclear, though Fukushima certainly didn't help. But solar killed nuclear just the same way it's killing coal, faster than reams and decades of EPA regulation ever could: By being cheaper and lower-effort. In any event, I *did* say back in January that commodity DRAM prices were on the rise again, and if you knew you were going to be building a new computer post-Ryzen/Kaby Lake launch, you might as well be scraping deals for memory between then and now. I feel slightly prophetic over that. =3 SwissArmyDruid fucked around with this message at 20:03 on Apr 14, 2017 |
