I won't lie that 6c/12t CPU will be real tempting if 1. Coffee lake will support the z170 and 2. MSI updates my bios to support it.

Particularly if it manages the Kaby Lake ~5ghz clocks with some reliability. I'm skeptical of its thermal limits, though. It's 50% more work being done in the same area. Kaby Lake is already hot, and you know full-well Intel is going to keep using that freaking cheap paste.

I imagine the 7700k will stay in the lineup and those will all cost more, if the 8700k will be 500$ or more my interest would be pretty low, for that price you get a top of the line Ryzen with more cores / threads and highly competent at current workloads / games. Unless of course it somehow blows Ryzen out of the water...

If we are placing bets on 8700k pricing it will probably follow the 7700k and be around 350. But this is intel so 400 because their cost hasn't changed since the 7700k and i suspect the 8700k is a bigger die then the 7700k so yields would be an issue.

Yeah for the pad to fry but not the trace id say high resistance at the pin causing it to heat up. Dust, finger grease or poor contact.

Is it possible to apportion blame for SKL-X's relatively poor gaming performance between the new cache layout and the mesh? So far the results seem fairly disappointing overall, but I haven't seen any reviewers delid it yet, and the thermals make it pretty obvious they're not getting what the chip is really capable of. Not sure it's enough to save it though, it gets you maybe another 10% at most. There's also always the chance there's BIOS or software tweaks that need to happen, so I'm not writing it off 100% yet but it's not doing anything that justifies double the price of Ryzen (or really makes me want to replace my 5820K). This was really Intel's game to lose, hopefully they do better with Coffee Lake. All I'm really after is Kaby but with more cores. Quad channel RAM would have been a nice perk that might have pushed me to X299 but it looks like there's too much of a compromise in gaming performance to make it worthwhile.

If Intel cares about X299 they should work on a 6/8/10 perhaps even 12 core Coffee Lake X lineup with the "old" ringbus. X299 is a failure because Intel rebadged datacenter-optimized Xeons, not expecting any competition. Or maybe they think the market is too small to put more effort into it. That's why BW-E has a clock-for-clock advantage on most gaming workloads. Intel tried to make up for it with frequency and obscene power consumption but the results are obviously not great.

You'd think that but Skylake-X has worse IPC than Broadwell-E (and Kaby Lake and probably even regular Skylake) in many if not most games. Intel PR even acknowledged this to the german press (PCGH).  google machine translation posted:The 'mesh' architecture of the Skylake X family differs from the 'ring' architecture of the Broadwell E family. As far as Skylake-X is concerned, we have found in a handful of applications that comparable Broadwell E processors are slightly faster due to these differences. However, the development of a new architecture requires some compromises to achieve the goal of a general improvement in performance. This also applies to the mesh architecture of Skylake-X. While these compromises have a slightly negative impact on a handful of applications, the Skylake X processors deliver an excellent performance per core and significant performance gains across a variety of applications, thanks to the new architecture." it just so happens that many games are a part of this "handful of applications".

Khorne posted:Buying a 3700k was a solid investment for me. My CMOS battery died last week, and my score in benchmarks is higher than many people with current gen cpus. My only complaint is that I have win7 home pro which has a 16gb ram limit and I really want 32gb or more of ram now. Web browsers eat ram like candy in 2017, and I run a few vms. ECC would be nice too, but it's not like newer generation home stuff has ecc either. I don't think I've ever owned a primary desktop computer for going on 6 years before. Your 3770k will overclock to at least 4.3 on air, easily, so do that if you haven't yet. If you bought Windows 7 and have a key, that key will upgrade you to Windows 10 Home. Just download the Windows 10 installer, build a USB boot drive and input your 7 Home key. Otherwise you can download the Windows 10 Assistive Technologies eye and upgrade to Win 10 Pro for free. No good reason to stick with 7 these days, especially if it's holding you back.

Actually, I've always had a question about overclocking it. I have it set to a x45 multiplier and 1.330v, but it usually draws 1.28v maybe 1.31v running prime95. Is this because of my motherboard, just how it is, or what's the deal? I have an ASRock Z77 Extreme6 if it makes any difference. I also noticed putting voltage higher than 1.325V-1.330V to say 1.35v made little to no difference in stability at higher clock speeds Khorne fucked around with this message at 19:10 on Jul 23, 2017 |

Good news everyone!   Vcore doesn't seem outrageous either, at least not for KBL standards where 1.415V would be considered acceptable for everyday use. If CFL-S really clocks that well I'm definitely going to replace my R7 1700 system because I'm tired of waiting for KVM virtualization fixes.

The performance seems fishy, too--6C x 5Ghz = 30, and 8C x 3.7Ghz = 29.6. Seems a little too convenient that this nearly 1:1 but with CL every so slightly ahead ratio is also what shows up in the performance bars.

Just sounds like slow voltage or an overambitious clock, yeah. Testing with 5 rounds of Intel Burn test on Standard (10 Higher later on) and following up with Prime95 for a bit for half an hour (4-8 hours after you've set it to a milestone) usually caught all my issues. Granted, this was for my i5-760 Lynnfield, but it was a great guide. I thought I could go way higher, but I decided to test rigorously instead of being bold, and I'd end up with Prime95 failing by the fourth or eighth hour of testing instead and had to just my glee accordingly.

its still happening even though i ended the overclocking entirely (which had been stable for ~5 years), my working theory is it's just the electromigration that can eventually occur in long-term overclocks

Big AT review of the i7 7740X and i5 7640X http://www.anandtech.com/show/11549/the-intel-kaby-lake-x-i7-7740x-and-i5-7640x-review-the-new-single-thread-champion-oc-to-5ghz Short version: The fastest single threaded CPU, so games/productivity stuff is good. But you pay a $100+ premium (with the mobo) over the 7700k that has 95% of the performance. And the i5 7640X makes zero sense.
