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.

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.

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.

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.

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.

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++.

Not sure if you were being sarcastic, but the 8600K doesn't have a 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.

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.

They don't come with a cooler!!!!!:lol:,, Intel sells their unlocked processors without heatsinks because overclockers will pretty much use liquid set ups or buy their own.
 


Pretty much this. AMD has nailed the price/performance sweet-spot with the Ryzen 5 1600/X hex cores --- especially with the combo deals out there.

Not quite enough to move me off my FX-6350, though :lol: maybe if THG would work one into the charts at 4.7GHz or so for comparison (hint hint)

With the extra costs involved it's too tough to beat the Ryzen 5s and the Kaby/Sandy i5s just to be "King of The Hill for A Day" ...

These 1080p 240Hz gaming monitors have been popping up recently. The gaming benchmarks at 1080p show that none of them can reach 200+ fps on modern hardware. Even overclocked to 4.9GHz, you'll have to reduce the settings if you want to see the full glory of your new 240Hz monitor. Or play Half Life 2.

That price difference is enough to get a GTX 1070, vs a GTX 1060 6gb. Unless a game is stupidly CPU bound, there is no way an i5 with a GTX 1060 6gb, is going to beat an r5 1600, with a GTX 1070. Also, I play @1440p, so the CPU gap is shorter anyway. ;)

1) Chipset does not dictate VRM design/quality
2) There are plenty of people getting good overclocks with B350 boards. I mean, Ryzen isn't a great overclocker overall, but you're probably not going to be (significantly) limited by your mobo. Especially because Ryzen isn't particularly power hungry.

The i5-8500/8600 are even worse off. They have a 2.8Ghz base clock and absolutely no promises to boost any higher. It's pure silicon lottery with those and remember, they didn't quality for the K-series, so no way are they going to boost as well as those.

Eh, AFAIK for at least the last several generations you could pretty much assume that an Intel CPU would maintain its max boost clock indefinitely under load, unless you had crap cooling or something. I don't know if there's any reason to think things will be any different for Coffee Lake.

First of most of us don't need a CPU cooler, I have liquid. Second there is no comparison between the i5 8600K and Ryzen 6, At gaming the i5 cleans the floor with it.. Is easy overclockable to 5+GHz.. Is like comparing Ferrari vs Ford Focus and saying the ford focus is cheaper, well duh. Also at greater resolutions the games are really GPU intensive and the bottleneck is not on the CPU. But when the newer generation of graphics cards roll out, we may start seen a bottleneck at 1440p like i do with my 2 GTX 980 Ti when using a Ryzen CPU.

I said if buying new, not upgrade an existing rig. ;) Also I do not care how high you clock that i5. If paired with a GTX 1060 6gb, a R5 1600 with a GTX 1070 will beat it every time, unless said game is stupidly CPU bound.

The Intel i5 8700K or any other intel's rated K processor,.. they are not for the average people trying to save money, they are for enthusiasts and overclockers...

If you want a CPU that comes with heatsink and fan included or trying to save some money... you should be looking at the 6 core i5 8400 is only 187 (actually cheaper than your Ryzen 6) and it has a turbo clock of 4GHz.. spoiler (still beats Ryzen at gaming).. Any more questions or concerns lol?

You can be an enthusiast and still value performance per dollar when making a purchase...

Ugh, why do people insist on using that site. Try this instead: https://www.techpowerup.com/reviews/Intel/Core_i5_8400/18.html
I'm looking at the values for the 1600X, because the 1600 can be overclocked to the same performance with basically no extra cost. The 1600X performs 5% worse at 1080p, 0.6% worse at 1440p, and 2.6% better at CPU tasks. In reality, the performance deficits in gaming would probably be a little less (and the performance advantage in CPU tasks a little greater) for an OC'd 1600, as you can most likely OC it beyond stock 1600X levels. And it'd probably still be cheaper, given that you currently have to pair an 8400 with a more expensive Z370 mobo. Seems pretty competitive to me
