Different mainboard vendors will interpret the 8700's 65W TDP limit more or less liberally on Z370, making it behave much like a stock ~100W 8700K. Good luck finding any reliable info on who or what exactly with which Bios version though. sauer kraut fucked around with this message at 18:50 on Dec 20, 2017 |

I have an 8700 non-k and I played with the all core turbo 4.6ghz boost thing. I got it working with the Beta BIOS on Asus STRIX Z370-E board I have, but it was auto setting the voltage to 1.35+ and generating more heat than I wanted to deal with. Instead I went back and just manually set the TDP in the BIOS to 95w, and now it will sit at its 4.3ghz all core turbo all day at stock voltages, nice and cool.

Canadians - the asrock z370 taichi is on sale at newegg.ca. This is a primo overclocking board and it's what I wanted to get when I ended up buying the gigabyte gaming 7 on black friday.

Why should I drop a ton of money on new Intel silicon for marginal per core performance over this thing that owe me nothing any maybe get an extra 2 cores if I spend even more for an i7 when I could just wait for Ryzen2 or whatever and double my core count.

If I was upgrading from sandy or ivy now, I'd go all in on an 8700k, delidded on water and optane. That might be the biggest change you'd see in the next decade.

WAR DOGS OF SOCHI posted:Honest question: If I've got NVMe and a lot of fast ram, what does optane do for me? Provided you're talking about the 900p and not the "cereal box insert" 16 and 32GB M.2 sticks, Optane is better tuned for general computing tasks - low queue depths, better small file performance, lower latency, and a lack of reliance on TRIM/garbage collection. It also has the speeds to excel at tasks NVMe was good at - database stuff, large file processing, rendering, etc. ...you're still going to be hard-pressed to notice much of a difference in games and the like over an SATA III SSD, though. The 900p comes with a code for Star Citizen that you can sell for ~$125-150, though. BIG HEADLINE fucked around with this message at 08:09 on Dec 23, 2017 |

My 850 evo is still serving me well.

Optane is for people who want an in memory database but can't afford the RAM. The cost isn't worth it for typical desktop use.

It's also one hell of a ZFS SLOG device and can get you near-SAN kinds of performance for a couple orders of magnitude lower cost. It is insanely good at low queue depth transactions which makes it potentially an issue for the busiest kinds of SANs, but given below QD8 is where it's fine it should be perfectly fine for most middle-class man's SAN.

A while back someone here brought up the problems of AVX-512 causing severe clock reductions and reducing performance on mixed workloads. Interestingly enough Skylake-X/Xeon-W do not seem to have this problem, the reduction is more like 10-20%. Intel also mentioned them as being manufactured on 14+ in their marketing material, while Skylake-SP is listed as 14. InstLatX64 is theorizing that Intel panicked and pushed -X onto 14+. I guess a further implication is that 14+ might be better able to withstand the power of AVX-512 at full tilt. Also, unlike Skylake-SP, all Skylake-X processors (including i7, not just i9) have dual AVX-512 ports, in contrast to Intel's earlier statements to Anandtech.

Otakufag posted:Is it recommended to replace the stock cooler that comes with a 8700 non-k with something better? You *can*, but you don't have to. The stock cooler is engineered to handle more than the listed 65W TDP - if you wanted something quieter which didn't have to work as hard fan-wise to push airflow, that's really the only reason you'd consider going with an aftermarket solution. That and *maybe* if you were forced to have the computer in a high-ambient environment or the case didn't have decent ventilation. If the computer's in a temperate room and the case has decent positive pressure, you shouldn't need to change the stock HSF. One thing you *might* consider is very carefully removing the fixed thermal 'goop' Intel puts on their stock units and replacing it with a more thermally-conductive TIM.

RAM speed question: How big of a deal is 3000 MHz versus 2666 MHz with Coffee Lake? I know it's a big deal with Ryzen, but is the 8700K going to see gaming differences between the two? Is it worth the extra $40 for 16 GB?

It might cost you ~1-5 *minimum* FPS in games, depending on the game. Not average or maximum FPS (which is more dependent on the CPU/GPU working together), but minimum. Faster RAM has demonstrably shown gains in 'smoothness,' even if you'd have to look at benchmarks to find it out. What else could you do with the $40? Make up the difference between a 1070 and 1080?

True enough. I'll not worry about it and go for the 3000/3200 instead. I'm finally putting together a new CPU/MB/RAM to replace Sandy Bridge. Poor old thing is bottlenecking my 1080 Ti in a number of games.
