AVeryLargeRadish posted:I read it as 65W for one core at full boost and the others at whatever they can run at to stay within TDP limits, much like boosting works on Intel's CPUs. If it is not 8c turbo TDP as I previously mentioned, the packaged cooler will thermally limit the chip which is not good. Maybe the 1700 65w TDP is at idle  PC LOAD LETTER posted:That is normal. Even Intel's chips only run the boost clocks at peak for 1 or 2 cores for long periods of time. I missed a single word but still implied 1 core at load is basically idle for an 8 core chip.

Maybe the 1700 65w TDP is at idle I can't tell if you're being willfully obtuse at this point or not. 65W TDP is for 3.0Ghz baseclock across every single core, and may include one core turboing up to 3.7Ghz. It's almost exactly the same scenario as a 6900K, but I guess you're right, the 6900K clearly uses 140W on loving idle clocks. Wait, are you trying to imply that single core turbo is just a single core in use? Hahahahahahahahahaha, holy poo poo.

GRINDCORE MEGGIDO posted:@Paul MaudDib - whoah, so with AVX a big Intel chip, overclocked, can go around 340W? Cooling them quietly must be a good challenge, holy poo poo. Paul MaudDib posted:Corsair did some stress testing of clocks versus required voltage. I'm not sure what their stress test was (i.e. whether it's AVX or not) but it kind of gives you an idea of the curves involved here. Oh and potentially obvious statement here but the scale starts at 3.5 GHz, so it tends to make this curve look less steep than it actually is. We're talking about basically 20% of the frequency range actually being visible in this chart. The curve gets REALLY steep in the last couple hundred MHz. Here's my attempt at resizing the chart to scale. Please forgive my ghettofabulous Paint.net skills.  Obviously it's probably not flat like that...

Regarding OC potential. There are three rumors out there. 1. OCUK tested a 1700 and hit 4050Ghz on the big ASUS board. Other boards fared worse, with top OC speeds around 3.8Ghz. quote:We just tested a 1700, it hit 4.0GHz stable in everything, but ONLY in the Crosshair mainboard, the lower-end boards it was hovering around 3.80GHz as the VRM’s were cooking with extra voltage. It however was maxing around 4050MHz, so I’d say 1700 can do 3.9-4.1GHz, of course the 1800X will probably do 4.1-4.3 as no doubt better binned, but if your clocking the motherboard has a big impact on the overclock and so far Asus Crosshair and Asrock Taichi seem the best two. 2. During the unveil presentation, AMD invited some known overclockers to play with Ryzen. They managed 5.2Ghz+ on liquid nitrogen (about the same that 6900k can do), and smashed the world record in cinebench R15 for 8 core processors. quote:The record run shows a group of overclockers putting an AMD Ryzen 7 1800X chip through the test in Cinebench R15. The chip was cooled with LN2 and voltage was bumped to an outrageous 1.875V. This allowed the overclockers to push this chip to 5.2 GHz across all 8 cores using LN2 cooling which kept the chip operating at a cool -200c. This is absolutely amazing for a chip that is yet to be released for consumers. 3. Donanım Haber, one of the biggest tech sites in Turkey, got their review samples from AMD and shared a video about it. They did not share any specific data, but were highly pleased by the performance. quote:https://www.youtube.com/watch?v=UhKmeCdB914

"Single thread score will be so great. According to this performance we can say that 7700K will be history, even for gaming, from now on" he said." It'll be crazy unbelievable if that statement means both are stock, or both are overclocked, in typical game engines that don't care about >4 threads. Infact, it'd be crazy unbelievable if it even matches a 7700K in either above case. The Lord Bude posted:If we're going to move to a single thread for intel and AMD I feel it's only right that there be a hyperthreading joke in the thread title. And platfrom.

Don't know really, but 5Ghz Kaby is plenty strong at gaming and not an unrealistic clock at all, unless you totally lose the silicon lottery. Highly threaded engines hopefully love Zen, though. The multicore performance seems strong, we do know that. I totally hope it's faster, even if it dents the resale value of my chip. It just seems the claims are getting more outlandish as time goes by. GRINDCORE MEGGIDO fucked around with this message at 06:09 on Feb 25, 2017 |

Two things collaborate to a strong Ryzen showing for games. 1. Games tend to use more cores/threads nowadays, and this will change even more as we move forward. A couple of interesting articles. https://www.computerbase.de/2017-02/cpu-skalierung-kerne-spiele-test/ http://www.eurogamer.net/articles/digitalfoundry-2017-how-amds-ryzen-will-disrupt-the-cpu-market 2. Ryzen seems to have a pretty competitive IPC, as well as (presumably, if Ryzen Master is to be believed) the ability to OC less cores higher if needed. http://www.cpu-monkey.com/en/cpu_benchmark-cinebench_r11.5_single_core-2 Of course, the above is mainly speculation. We will have to wait for the reviews. Dante80 fucked around with this message at 06:24 on Feb 25, 2017 |

All of this talk about the ASUS Crossfire variant being more efficient at overclocking is getting me scared. I was forced to get one of those Asus Prime x370-Pro due to mostly everything else being sold out. I'm willing to spend a little more to give my CPU the chance to overclock to the fullest, I just hope I don't get screwed if it's really the case that this cheaper board will perform much less on providing power to the CPU.

Dante80 posted:Two things collaborate to a strong Ryzen showing for games. Eh, I'm not sure what Ryzen will do that the last 3 years of games targeting the 8 weedy jaguar cores of the consoles didn't accomplish. And it still seems to be the case that if the CPU is what limits performance, it's mostly about the single core grunt. The i3 7350K smokes a lot of mid-range quad-cores if you run it at 4.8 ghz. I'm expecting the stock 1700X to lose to stock 7700K in practical gaming benchmarks, and oc'd comparison to push it even farther in intel's favor. But that's still complete speculation, we'll see how much extra the per-core dynamic clocking of Ryzen can extract from it.

Anime Schoolgirl posted:i would have thought the 4 core chips were bins but they're appearing 6 months later Yeah, with them coming that much later I assumed that they will be physically different chips. I could be totally off base here of course but the much later launch of the lower end chips makes more sense in a scenario where they need extra time to get new production lines up and running and time to build stock so the launch of the lower end chips doesn't fizzle for lack of availability. Also getting twice the chips per wafer is pretty important to keep costs reasonable. Of course this isn't ideal since it gives Intel more time to respond with price cuts but if the R3 top end chip is $140 and clocks to 4GHz like rumors suggest it's going to absolutely murder Intel in the i3/i5 market, there's a lot of volume there so it could hit Intel pretty hard in the bottom line even though profit per chip is way lower than in the server/HPC space.

Look at you nattering nabobs of negativism. It's not like the last 2 major architectures AMD has released both had critical flaws that were revised in a subsequent refresh, or anything. (Not that Intel hasn't had oopsies either, but in comparison...) Also, it's pretty funny how on the quantum hype-train the overclocks are both awesome, and perhaps have some severe problems but are definitely getting better in the next BIOS, all at the same time...

Maybe that's the reason for the staggered releases, the oddly separated dates may mean new steppings and any actual bins currently would exacerbate the current problems.

nifty graphs compiled by 3dcenter:  EA's upcoming Mass Effect: Andromeda is rumoured to scale better with threads than frequency. It's just one title but regardless great timing for AMD because those benchmarks will make the rounds during the launch week.

I won't exclude the possibility that AMDs first patch of B stepping has some fuckery in the L3, but the reports of bad BIOS's, poor memory performance, low number of boards, potentially of better OC with better BIOS, etc makes it sound way more likely that AMD's board partners are lagging behind. Hell there was some report back in December that AMD has been ready for months but has had to sit on their hands while ASUS, MSI, Gigabyte, et al play catch up. AMD is probably pushing this out now to maximize the window they have between Intel desktop releases to establish mindshare. I'll probably be sitting on this 4590 until later this year anyway, the only thing I'm buying from AMD within the next 6 months is a GPU. Hopefully if there are any serious problems they'll be resolved by then.

Well when we got to 3D tech for SSDs, it really makes sense that we should have 5 dimensional hype trains to stay ahead of the curve. Still excited about Ryzen. Hopefully my laptop will hold out until Ryzen/Vega APUs are available for mobile.

If you do plan on overclocking, you could pick up some MOSFET heatsinks. Something like these Enzotech heatsinks would work. Pack of ten, so just enough to cover all the VRMs.

I wonder how much thermal headroom you get if you disable hyperthreading. You aren't going to need 16 threads most of the time anyway. If no hyperthreading means higher clock speeds, that could mean better performance in typical high demand scenarios (vidja games).
