Intel Readies Four 6-core "Coffee Lake" SKUs, Including Two Core i5

Intel is beginning to feel the pinch of AMD Ryzen 7-series, and the upper-end of the Ryzen 5-series, which offer better multi-threaded performance than similarly-priced quad-core Intel Core i7 and Core i5 "Kaby Lake" processors, and reasonably good single-thread performance, and platform costs. The company is responding in force with four new six-core SKUs, and for the first time since "Nehalem," the company isn't changing the socket with the introduction of its third mainstream-desktop micro-architecture on a given process. The 8th generation Core "Coffee Lake" mainstream-desktop processors will be built in the existing LGA1151 package, and will hopefully support existing motherboards through BIOS updates, even though Intel plans a new 300-series chipset to go with these chips.

The six-core "Coffee Lake" processor lineup addresses not just the higher-end of the lineup with Core i7 SKUs, but also the mid-range of it, with Core i5 SKUs. One of these could even scrape the sub-$200 price-point. Of the four confirmed SKUs are the top-dog Core i7-8700K, its slightly cheaper sibling, the Core i7-8700 (non-K); and the Core i5-8600K, with its cheaper sibling, the Core i5-8400. Of these the i7-8700K and i5-8600K are unlocked. The Core i7 parts feature HyperThreading enabling 12 logical CPUs for the OS to deal with, and 12 MB of shared L3 cache; while the Core i5 parts lack HyperThreading, and only feature 9 MB of L3 cache. The clock speeds and other features are tabled below. The company plans to launch these four either by the end of Q3 (late-September) or some time in Q4, before Holiday.

i5 8600k 6 cores, no HT, overclocked to 4,8ghz + Day 1 working 3200mhz DDR4. Sweet spot for high refresh gaming. Here we go.

Liviu Cojocaruprobably you don't realise that the 6700K was almost the same as the 7700K but now with the 8700K being a 6c/12t is a totally different situation. so to ask around 350£ for a 6c/12t cpu and keep the 7700k ,which is a 4c/8t, at around 320-330£ will be impossible ;)
But even so, none of ghe old extreme editions dropped in price significantly when the next generation arrived. Even the 6950x only dropped from 1700 to 1550 in Holland after the 7900x arrived. Seems to be a similar story in most places. So a 40% cheaper cpu only causes a relatively minor drop in price for the cpu it replaces.

Your example is an HEDT so it will not be the same thing. Also the second hand market will probably see a rise in i7's 6700K and 7700K

Prima.VeraI never understood the purpose of a non-K CPU. I mean who in the right mind would buy that locked crap with even lower freqs than the K variant, only for a couple less $ ???
Seriously, those must be the most useless CPU's ever.
Well to be perfectly fair non-K CPU's were fine on Z170 shame Kaby Lake put the squash on that...can't have consumers getting their money's worth out of incremental performance upgrades...god forbid overclocking come free who ever heard of such a thing ;)

Really shows what lack of competition does when this -not changing socket and scaling to 6/8 cores- could have been done since 1155/SB.
Oh well, let's see how they fare. :oops: More aggressive price/performance ratios is what we need.

That's what I always thought, but Intel us fairly predictable and always works the same no matter the target market. Now there finally is proper competition, Intel is changing things up a bit, but a massive price drop will make Intel seem like cheap sh*t to the generic ignorant buyer and Intel doesn't care about old cpu's, so retailers don't either.

Remains to be seen, my opoint is that it will be very strange to see a 4c/8t priced very close to a 6c/12t ...

I would be interested in that Core i7-8700 that does 4.3GHz on 6 cores at just 65 Watts!
Would be nice if it runs on my Z170 Pro gaming motherboard....

I doubt Intel will keep offering both at the same time. At the same time, I'm sure not all retailers will clear stock in a timely manner and of those that don't some will keep the prices for Kaby Lake CPUs up, just because they bought high and hope to not lose money and sell to the clueless.

Purpose? a lot of them. You can save 100 bucks by getting a Hxxx motherboard instead of a good Z one. You get a 65w TDP chip instead of a 90w, You get a cooler bundled with the CPU, wich is already cheaper upfront (usually cheaper by 15% to 20%), and you still get an amazing chip. You also don´t need a beefy 50 bucks air cooler or AIO water cooler. Not everyone is into overclocking, so having the locked CPU option is always good to save money

That's boost. It will probably sustain 4.3 until it gets too hot and then throttle. But if you manage to cool it well enough it will (at least theoretically) sustain 4.3GHz.

@Manu_PT It's so funny when people get so out of touch that they forget overclockers are a minority and there's a whole different world out there :D

I know that, I can cool my i5 6500 which is a 65 Watt CPU as well, it runs about 50 core temps max while gaming so I wouldn't see any problem why this i7-8700 would throttle.
Since I can keep it cool I would expect a 4.3GHz speed for gaming, which is a nice upgrade and good enough for me.:)

And of the overclockers most only slightly oc to sustain higher clocks without pushing the cpu to its temperature and voltage limits.

But the 6500 isn't really a 65W tdp cpu in exactly the opposite way to the 8700. The 8700 is a 95W tdp cpu with slightly lower clocks to actually give it a real 95W tdp. If you use a good aftermarket cooler, you should be fine, otherwise you can expect some throttling.

I can read right!? It says 65 Watt on that slide....

But I tel doesn't give a sh*t about realistic heat production. For example, if you want to run a 7900x at it's maximum stock speed, you need a much better cooler than the most basic 125W tdp cooler. 180W threadripper 1950x may actually need a less good cooler than a 125W tdp 7900x to run it at its max clockspeeds without throttling.

AndreiDSuuure, that's why a 6C/12T 7800X is faster than an 8C/16T 1800X in most applications because Zen "beats Skylake-X at literally everything".
I swear, some people just let their favoritism of a multi billion dollar publicly traded company get to their brain and spout the stupidest things ever.
Rule number 1, never link to Anandtech.
Rule number 2, do your research better

Read it!!! i7 8700(non K), TDP 65 Watt....... If it was 95 Watt they would have stated so wouldn't they?

It's almost like the chips with lower clock speeds have lower wattage! Fancy that!

But not THAT significantly and real cooling requirements differ quite a bit (mostly negatively) often times with Intel cpu's. Ryzen cpu's actually can make do with crappy 65W/95W tdp coolers without throttling. Intel cpu's often can't. Interesting isn't it?

Right but that i7 is labeled as a 65 Watt TDP CPU, not 95 Watt, that's my point....

I think you're close, but it's more like: if we sell this for overclocking, let's give it some more TDP leg room so it can actually overclock without throttling back all the time.

Tdp is BS on Intel cpu's nowadays. You should never trust anything a manufacturer says without the facts to back up their claims. Often there is a lot of fine print involved.

Tdp does nothing for overclocking. Higher power limits does.
