Apple has made no secret that new Intel Macs will continue to be released, despite the announcement of the transition to Apple Silicon chips (and the first machines at the end of the year). Ming-Chi Kuo even mentioned a refreshed iMac for this summer, pending the much-awaited redesign of the all-in-one. A benchmark appeared in the Geekbench database could well lift a corner of the veil on this summer model.
This new iMac, which has endorsement number J1851,1, has a Core i9-10910 processor (10th generation, Comet Lake S) running at 3.6 GHz with Turbo Boost up to 4.7 GHz. The chip has ten hearts (20 threads), a L3 cache of 20 MB. It could be a faster version of the Core i9-10900 whose base frequency is 2.8 GHz: the chip of this iMac would therefore be 28.6% faster (nevertheless, the Core i9-10900 has a more powerful Turbo Boost, up to 5.20 GHz).
The TDP thermal envelope would be 95 watts, according to Tom’s Hardware who reports the news. If the Core i9-10900 is known to Intel services, this is not the case for the Core i9-10910. The founder regularly designs specific chips for Apple, and this should not change despite the Apple Silicon transition (read: Mac Apple Silicon: Intel confirms the transition smoothly).
This new and still mysterious iMac, which would be a 27-inch model (only this diagonal accommodates an optional Core i9), would benefit from an AMD Radeon Pro 5300 GPU still unknown. It could be a desktop version of the Radeon Pro 5300M launched last year (Navi 14).
