The theory is that this will be a special edition of the 10900K CPU, a specially binned model – meaning Intel will select the choicest silicon for the chips – which means it can be pushed with slightly higher clocks, much like the 9900KS before it (that offered an all-core 5GHz boost – it remains to be seen what avenue Intel might take with the 10900KS).
Of course, just because it has popped up in a document, doesn’t mean this processor is inbound – the listing could be some kind of a mistake (maybe Intel previously planned to deploy the CPU, but has changed its mind since). A number of scenarios could apply here, so we certainly can’t take anything for granted – but that said, it’s definitely a possibility that there is a 10900KS on the horizon.
If it does eventually emerge, the 10900KS will seemingly come bundled with a copy of Crysis Remastered, as per the aforementioned Intel document.
Intel appears to be on a big counter-attack against Ryzen processors at the moment, with Comet Lake prices being cut substantially at retailers, and this could represent another offensive against AMD which is currently struggling with stock issues and supply of new Ryzen 5000 CPUs.
