It seems that while Apple has decided to move away from the Intel x86 architecture on desktop platforms to an ARM-based self-research processor, that’s not an overnight thing, and in the short term Apple will rely on Intel. A new Apple iMac all-in-one, numbered “AAPJ1851,” has emerged in the GeekBench database, and the processor is the never-before-seen Core i9-10910, apparently a custom version of Apple.
In terms of specifications, it has 10 cores of 20 threads, a reference frequency of 3.6GHz, a maximum acceleration of 4.7GHz, and a three-stage cache of 20MB.
Compared to the released i9-10910, its reference frequency is 800MHz higher, but the acceleration frequency is 500MHz lower, and compared to the flagship i9-10900K, its reference, acceleration frequency is 100MHz, 1GHz lower.
Thermal design power consumption is unknown, from frequency guess may be around 95W, lower than the i9-10900K 125W and higher than i9-10910 65W.
Interestingly, the new iMac’s graphics card is also an unreleased “Radeon Pro 5300” that detects 20 computing units (1280 stream processors) with a core frequency of up to 1650MHz and 4GB of memory.
It looks like it’s a desktop version of the Radeon Pro 5300M, which is the core of the Navi 14 GPU, with a full 400MHz increase in frequency (the full card must consume more than 50W), the same memory capacity, and it should be 12GHz GDDR6.
