Intel Core i7-8700K "Coffee Lake" De-lidded, Reveals Larger Die

A member of the HKEPC tech community, with access to an upcoming Core i7-8700K six-core mainstream-desktop processor, wasted no time in de-lidding it (removing its integrated heatspreader or IHS). It was revealed that Intel is still using thermal-paste between the IHS and the CPU die. The "Coffee Lake" die itself is as wide as the "Kaby Lake," but is visibly longer. It has a die area of approximately 151 mm², compared to the 126 mm² of "Kaby Lake." This is due to its increased CPU core count to 6, and a proportionate increase in last-level cache (L3 cache) to 12 MB. The die is marginally northwest of center, so you can get away placing your TIM blob dead-center of the IHS.

There wasn't any die shrinks in the process, so all of this makes sense.

Yeah in 1 year 9700K intel gets real with 176 mm2 8-core. Could be 10 core if integrated video is replaced with another 2-core.... 6-core is just odd despite being even.

4 cores and igpu is 126 mm2.
6 cores and igpu is 151 mm2.
that makes the size of igpu 76 mm2 and single core 12,5 mm2.

edit:
ppn is right, 8-core with igp would be 176 mm2. 10-core with igp would be 201 mm2.
since the comparison should be relevant, ryzen is around 195 mm2.

Bigger die size is great. There's a reason the 7980XE runs as cool as it does despite using thermal paste.

Huge emphasis on the word "cool" here.

But yes, people will also be surprised by the actual power consumption of those chips.

A Noctua D15s being able to tame that beast is a feat on its own.

To be honest I was expecting a larger die than what it is.

If there is something good about this release, at least those KBL compatible delid tools are still compatible.

A Noctua D15s can cool it easily at 64c.

That was the OC, 5100mhz @ 94C 1.4v, I believe they had it under water too?

The 7980XE isn't soldered. None of Intel's current lineup is.
