So the new 27" iMac now is available with either a 10th sen i7 processor or a 10th sen i9,

Does anyone know the specific CPU model for the i7? (e.g., i7-10700T, i7-10700K, i7-10700, i7-10875H, etc)

You can take the base and boost GHz ratings from the iMac listings and correlate them with intel model numbers.

So the i7 is likely a i7-10700K with its listed 3.8GHz base clock, but the boost clock seems to be 0.1GHz lower than intel spec (likely for cooling reasons). https://en.wikipedia.org/wiki/List_...omet_Lake_microarchitecture_(10th_generation)

The i9 is likely a i9-10850K with its 3.6GHz base clock, again with boost 'detuned' by 0.1GHz compared to intel spec. https://en.wikipedia.org/wiki/List_of_Intel_Core_i9_microprocessors#Comet_Lake-S_(14_nm)

So they seem to be standard intel chips with boost ratings lowered by 0.1 GHz, the other possibility is that they are custom i7 and i9 models for Apple. Apple has been known to use 'K' series (overclockable) chips in previous iMacs for their higher stock and boost frequency despite there being no possibility to overclock the CPU in the iMac.

i9 is a 10910 by the looks of it:

You'll see other chips here too.

Interesting those geekbench multi-core scores from the custom i9-10910 are not that much higher than the 10700K, I expected more. EDIT: Actually there seems to be quite a bit of variation in that list. Do you think some of those 10700K scores could be from hackintosh users?

I think a lot of people don't make sure they close everything else down before running a benchmark. Also may be some experimentation going on (e.g. playing with fan speeds, CPU power limits etc). Some have to be taken with a pinch of salt on top of the pinch of salt you take when you look at artificial benchmarks.

Try to see what is the Motherboard model. If it doesn't begin with "Apple Inc." then it is Hackintosh.
