https://www.geekbench.com/doc/geekbench4-cpu-workloads.pdf The AES workload in Geekbench 4 encrypts a 32MB string using AES running in CTR mode with a 256-bit key. Geekbench will use AES instructions when available, and fall back to software implementations otherwise. CTR mode being the only test is a bit questionable in my opinion, CBC/GCM give the best representative sample from normal workloads. I suspect the changes that were made to the IPC architecture on the latest Intel chips make a performance for massively threaded modes like CTR but regular uses cases are probably about the same or a bit faster.

I just wonder how many 8700Ks are going to end up dead when the retail binnings can't hit 5.0 like the samples given out.

Unless Intel binned the entire initial allotment of retail chips they should be hitting 5GHz pretty easily with sufficient cooling like a 240mm AIO. I'm also seeing a lot of reports of chips hitting 5.1 and 5.2.

The only way to get intel to stop using that lovely TIM is to see someone else, like amd, crush Intel in competition. And the only remaining way for Intel to be competitive has to be to stop using that lovely TIM they've used for a decade+

This is all just nerd fodder. Most people are not buying a $1000 cpu. Most people are not overclocking at all. I have a 7700k and probably will never delid because why the hell risk it. It works well enough. Nothing is going to perform that much better with extra overclock. Granted it is a dumb decision at this point.

bobfather posted:"Assuming you don’t have a huge overclock" when every review site out there is squarely focused on the 8700k at > 4.8ghz. GamersNexus does have some good power measurement benches, I like their tests because they specifically focus CPU draw and not total system, and actually list the voltages on all the OC benches they include. https://www.gamersnexus.net/hwreviews/3076-intel-i7-8700k-review-vs-ryzen-streaming-gaming-overclocking/page-3 (And yea, for stuff like Firestrike, the OCed 8700k pulls the same power as a stock 1920x )

The thing that disturbs me is that two reviews have done streaming testing, and in both of them Intel smacked 8 core Ryzen around in terms of what the viewer sees. This seems like the one test where more cores would equal better. GamersNexus configures OBS like neither Steve or anyone else there has streamed to Twitch before, but TechReport tested with settings much closer to something a streamer would use bitrate-wise and won huge. Then again, in the comments it was mentioned that most any "modern" i7 (and who knows if my Ivy counts as that anymore) shouldn't have a problem running a game and streaming at veryfast profile, which was why they were looking at medium. I just want to stop using GPU encoding.

Erm, bolded should read "and Ryzen won huge", right? What's your GPU? AMD's VCE is very poor and earlier generations of NVENC are not great either. There is a noticeable improvement in Maxwell and Pascal's NVENC quality at low bitrates. It's kind of a fact of life that video encoding at the same time you're playing is going to destroy your framerate. The best way to solve this problem is a separate box to do the encoding, if you don't do that then it's all just a question of output quality vs how bad your framerate is trashed. Ryzen may let you get a bit farther into output quality but your framerate will still suffer just as badly as on Intel. (reminder: x264+x265 trunk builds have had AVX2 and AVX512 support for 6+ months now, but Handbrake is using an ancient x264+x265 build that doesn't support AVX512. No idea what OBS is using.)

Craptacular! posted:No, I meant to say Intel won still. Of course I know you but, I don't remember that incident. I assume that I said this already but you should have bought the faster card and underclocked it to get the TDP down, an underclocked 1080 could have hit 1070 performance at 120W TDP or less. Less TDP = slower fan speeds = less noise But whatever, nbd, get what you want - it's your system. What I will add re: your previous statements: people tend to underestimate the amount of stuff that AVX can be used for, and video encoding is one of them. Despite a lot of poo poo-talk about how Ryzen is revolutionary for mega-taskers and streaming, Intel processors are a lot better at AVX. AMD runs AVX2 at half-rate, and this is one of the things that leads to huge disparities since every reviewer insists on using Prime95 (an AVX synthetic) to bench power consumption (then proceeds to totally ignore efficiency/throughput entirely and just focus on raw power consumption). While rendering x264/x265, a 5820K has close to twice the AVX throughput of a 1600X at equal clocks. I won't say that means twice the render framerate but the difference isn't trivial either. quote:Unfortunately, I'm not charismatic and streaming is a total money sink for me with less than five simultaneous viewers forever Welcome to the 99%. Nobody watches my streams either buddy Like I said, if you have the money - overbuild your fileserver and encode video on it. That's the only "free" way out of the situation here. Everything else is going to have at least some impact on your framerate, and if nobody watches it anyway... Paul MaudDib fucked around with this message at 02:10 on Oct 7, 2017 |

Well, I'll keep an eye out for what AMD does next, but at least if I throw the money at 8700 non-K next year I know I'm not compromising on anything.

Be aware that you'll have to modify your cooler quite a bit if you want to run direct Die cooling with a shim. The part of the socket that houses the lever will be higher than the Die itself so the base plate of the cooler will interfere.

The one I am looking at is a total replacement for the socket retention bracket. It used to be a MSI thing but once they stopped including them the OEM continued selling them under their own banner (here). There are two different ones for 3-5 series and 6-8 series because of the substrate changes. I'm using a EK Supremacy waterblock so all I'd need is the replacement screws that go lower (Naked Ivy) and a local computer place has em for six bucks.

Guy who works at ASUS on BIOS's says the following at Overlock http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-thread/28240#post_26391661quote:AGESA 1007 comes with support for Raven Ridge APUs. AMD has also changed the entire BIOS base structure so we have to do a lot of work to port everything to the new version, which may result in further bugs. The advantage is that it makes it easier to support future CPUs (Raven Ridge, Pinnacle Ridge). The cold boot fix will be implemented as soon as we have a recent AGESA version which supports it. Which will probably be the main difference (besides maybe thunderbolt and USB-C) between X370/B350/A320 and X470/B450/A420, the 400 series will have all this baked in once on the shelves, while if you already have a 300 series you'll need to update the BIOS. I assume if 300 series boards continue to be sold they'll get updates to support the later chips as well.
