https://www.anandtech.com/show/11859/the-anandtech-coffee-lake-review-8700k-and-8400-initial-numbers

At the top of the stack are two Core i7 Coffee Lake processors. In previous generations 'Core i7' meant that we were discussing quad-core parts with hyperthreading, but for this generation it moves up to a six-core part with hyperthreading. The Core i7-8700K starts at a 3.7 GHz base frequency and is designed to turbo to 4.7 GHz in single threaded workloads, with a thermal design power (TDP) of 95W.

[...] In the middle of the stack are the Core i5 processors, with the new generation matching the 'same configuration without hyperthreading' philosophy that followed in the previous generation. The two Core i5 parts operate at lower clockspeeds compared to the Core i7, and perhaps more so than we are previously used to, especially with the Core i5-8400 having a base frequency of 2.8 GHz. Intel sampled us the Core i5-8400 for our review, because it hits an important metric: six cores for under $200.

[...] It is interesting to note that in the last generation, Intel had processors with two cores and two threads (2C/2T), two cores with hyperthreading (2C/4T), quad cores with four threads (4C/4T) and quad cores with hyperthreading (4C/8T). This layout had staggered, regular steps. With the move to 6C/12T on the high-end Core i7, and 6C/6T on the mid-range Core i5, Intel completely skips the 4C/8T parts and moves straight to 4C/4T on the Core i3. This is likely because a 4C/8T processor might overtake a 6C/6T part in some multi-threaded tests (it would also explain why moving from a previous 4C/8T Core i7 processor to a 6C/6T Core i5 8th generation is not always an increase in performance).

However at the bottom of the stack are the 4C/4T Core i3 processors, where Intel is pushing out an overclockable Core i3 processor again. This is a little bit of a surprise: in our testing of the previous generation overclockable Core i3, the fact that it was dual core was a setback in a lot of testing. With the Core i3-K now being quad-core, and overclocking it to try and beat a six-core chip for less money, for certain things like gaming we might see less of a difference between the two.

Also at Ars Technica. Intel press release.

    As much as I like being spied on...

      As Kaspersky has of not letting the Russians know when they detect malware and sending them a sample :)

      I would not expect that ME option rom (that is required) to disappear any time soon.

      The new stuff will always have it.

      The more invasive stuff is in the best chips; vpro and other such features.

      In many cases, prior to installation of one of the mainstream OSes that support it, you can sometimes disable the TPM stuff with a knife, though.

      yeah, i'm not buying any new stuff from either of these whores of the surveillance state. eventually i may buy used from ebay. if everyone would just boycott their current lines they would instantly remove it. you don't have to swear off all modern CPUs, just don't buy when they want you to. unfortunately, 95% are skanks who can't wait to buy as soon as their spyware hits the shelves.

    Looking at buying more high-performance PCs for work. The 8700K thread performance looks nice (missing the quad-channel DDR), but the friggin' TIM-instead-of-solder just aggravates me.
    The die runs hot, because Intel saves pennies on a $350 bucks part advertised for overclocking and (reasonable) enthusiasts.
    Does it run too hot? probably not. But that has a cost...

    The new 370 chipset is another layer of stupid. We need to buy PCBs anyway, so I'm not screwed out of upgrading, but don't go telling me the previous socket didn't support the 95W TDP...
