Intel Core i5-8600K Review: Coffee Lake's Jolting Value
Why you can trust Tom's Hardware
Civilization VI, Battlefield 1 & Dawn of War III
Civilization VI AI Test
Core i5-8600K claims a lead over the rest of our stock-clocked field, and tuning yields solid performance gains.
AMD's Ryzen 7 1700 lags the field considerably at its default settings, largely due to its 3 GHz base and 3.7 GHz Precision Boost frequencies. This is a tale of two faces, though. AMD slows down the 1700's base clock rate considerably compared to other Ryzen 7 models. However, overclocking pushes the chip to 1800X-class performance. This makes Ryzen 7 1700 a potentially great value for tuners.
Civilization VI Graphics Test
The Core i5-8600K is also nimble during our Civilization VI graphics test, taking the top spot. The -7600K suffers in stock form due to its four cores. But, like the Ryzen 7 1700, it responds well to overclocking.
Battlefield 1 (DX11)
We're graphics-bound at the top end of this chart, where Core i5-8600K makes its appearance. Meanwhile, the Core i5-7600K starts lower on our hierarchy and has to be overclocked in order to catch up.
Warhammer 40,000: Dawn of War III
The Warhammer 40,000: DoW III benchmark scales wonderfully with increased execution resources, but speedy clock rates also provide a big benefit. Intel's Core i5-8600K takes an easy lead over less expensive chips in both stock and overclocked configurations.

logainofhades Great CPU, but the overall platform cost is a bit of a turn off, for me. I'd rather get a 1600, and a B350 board, to allow for a better GPU, if buying new. As stated in the review, even a 1700, with a less expensive board, is a very compelling option.Reply

AS118 Seems like a good product, but I'd like to see what the 8600 and 8500 non-k offers, and perhaps next year with the B360 boards that give them a more budget "locked cpu" option.Reply
I also feel that the availability will be low for Coffee Lake until the end of this year, particularly throughout the holiday season. Due to that concern (as well as the total cost of platform ownership) I think that Ryzen with its 1600 and 1700 CPU's along with the 1600x will be the value kings this year, with Coffee Lake not hitting it's stride until early next year.
The fact that AMD's stuff doesn't have the same availability issues makes it a strong contender, imho, although Black Friday and Christmas sales will also like make Kaby Lake (and even Sky Lake) stuff at clearance prices appealing too, despite the lack of cores you'll find in Ryzen and now Coffee Lake. -
almostdecent Since the chart shows the i5-8600k and the i5-8600K@4.9GHz at the same $260, I presume that means you achieved the overclock with the stock cooler.Reply -
ammaross It's kind of disappointing to see so many benchmarks where an i5 does as well or better than it's i7 counterpart. It just shows how poorly threaded some of these applications really are and almost necessitates running two benchmarks simultaneously to really judge the merit of these multi-core CPUs. Maybe run the photoshop test while rendering with After Effects or run a game benchmark while doing CPU h.265 handbrake.Reply -
almostdecent It is worth mentioning that this is essentially a paper launch at the moment, since none of the Coffee Lake processors are available anywhere.Reply

and the rare place that has any, such as Microcenter, have gouging prices. Such as selling the plain i7-8700 (not the K version) with an MSRP of $300 for sale for $429.

On September 20, Intel responded to a story about yet another 10nm schedule slip by saying that Cannon Lake will begin shipping in limited quantities to some laptop manufacturers with production ramping up in 1H2018. Limited Coffee Lake volume could be due to Intel deciding to upgrade production lines to 10nm for Cannon Lake instead of 14++.20281291 said:I also feel that the availability will be low for Coffee Lake until the end of this year, particularly throughout the holiday season. -

Not sure if you were being sarcastic, but the 8600K doesn't have a stock cooler.20281420 said:Since the chart shows the i5-8600k and the i5-8600K@4.9GHz at the same $260, I presume that means you achieved the overclock with the stock cooler.
There are two different sets of graphs, one that looks at CPU only costs and the other that considers CPU, mobo, and cooler costs. In the latter, the 8600K at 4.9GHz is clearly shown to cost more.

Intel hasn't included a stock HSF with their unlocked CPUs since Skylake so on top of paying more for the unlock, you also get shafted by the price of a stock cooler which you no longer get on top of it. You need an aftermarket cooler for both stock and OC.20281420 said:Since the chart shows the i5-8600k and the i5-8600K@4.9GHz at the same $260, I presume that means you achieved the overclock with the stock cooler.
Same thing with AMD's Ryzen nnnnX CPUs. -

A better GPU?//Why would you do that. at 1080p Ryzen will (bottleneck) hold back powerful GPU's, It won't give you equal performance. I bought a Ryzen for pure gaming and i ended up selling it.. -

B350 VRM's are pretty low quality for any sort of OC unless it's a mild one so for me that's a no go. If you're primarily into gaming then the 1600 has nothing on the i5, it simply trails it whether at stock settings or OC'd and even at productivity it beats a 1600 Ryzen processors in most task even with a 6 thread deficit so it's a pretty good investment overall.
