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.

I have been a fans of facts and thus buying ONLY Intel CPUs over almost the past decade.
My 7 year old Xeon-1235 (Sandy Bridge) workstation just got old enough and I decided to upgrade, the choice became so obvious that it has to be Threadripper.
-Supports ECC RAM out of the box, no need to beg for a server CPU that has a funny lock removed (well server chipset as well).
-Give 64 PCI-E lanes, go check Intel's.
-$999, just two months after the release of the Intel $999 Skylake-X 7900, AMD will totally claim the champion of performance
Intel box coolers will happily maintain maximum non-boost settings 24/7 anything over that is turbo and is not calculated into tdp.
AMD box coolers are larger and they even went as far as to have the thermal sensor lie to the motherboard on the x series chips to keep the CPU in its boost bins longer. Their core throttling is also nothing short of Jim Keller's genius at work. Overall "TDP" in a stock chip is maintained quite well. You can really see the effects of this when you start turning AMD cool and quiet things off. Man that power consumption starts walking up...
My guess would be the attempt from amd is to provide a better gaming experience since they have the weaker performing cpu in that aspect. They will both easily throttle under the stock cooler and video rendering so that part is mute. This would be for anything not bundled with the wraith max cooler which is roughly equal to a hyper 212 (150w tdp)
Depends and that boost thing is dumb on Intel's part and the bit about AMD is a bit vague
(Ry)Zen 7( threadripper) actually performs similarly to Intel 8-core+ nowadays, so Intel is only partially better for gaming and the wraith spire can cool a r7 cpu at 3.9-4ghz on all cores, so it won't throttle stock.
Cross core latency unless you have a good 3200mhz ram kit leaves a lot to be wanted from Ryzen. Performance is not like an 8 core Intel in games a multitude of reviews show them lagging behind.
The fact is that the only CPU with any real advantage now is the i7-7700K with extreme cooling at 5GHz+, and only for 200Hz 1080p gaming. Literally any other situation is better covered by an AMD cpu. In fact Skylake-X has lower IPC than both Kabylake/Broadwell and Zen, so it is a wholly useless product line-up.
I await Threadripper diligently and hope the better binning for these chips allows a higher peak overclock even if it is limited by number of cores. Until then I have yet to have a chip that performs overall better than my years old 5960x@4.8.
Why not 8?? Is intel going for another 10 years with 6 Cores only?
Out of curiosity how many Ryzen systems have you built and tweaked?
But Ryzen 2 is apparently only launching in 2019, and I need a new system long before then, so Coffee Lake/Z370 is probably what I'm gonna go for. Despite my desire to support AMD's new CPU, the Ryzen platform as a whole is still too immature and feature-limited. Threadripper's 60 PCIe lanes are tempting, but that platform is also likely to have bugs, plus it's hella expensive. I may just end up going for KBL-X + X299 and dropping in a newer, cheaper, higher-core-count CPU as time goes by.LOL, the evidence is in literally any review of a Ryzen motherboard on the Internet. If you can find one that doesn't mention memory compatibility issues, you have a case; until then, stop trolling.
Coffeelake is lucking like a clusterf***. Z370 up to 6 cores, but not z270, so you need a new mobo anyway for the 6-cores AND new 300 series mobos that do NOT support old cpu's! That's going to confuse many people.
