Has it been mentioned anywhere that 2 cores will be dedicated to System OS for PS5 and XSX? surely 1core2 thread Zen2 beats any performance from 2 jaguar cores currently? in fact I'm pretty sure the PS4 only uses 1 as I remember guerrilla games saying they coded Killzone shadowfall to use 7 cores, although the PS4's OS is very lightweight so maybe xbox one required 2 cores because of the hypervisor running 3 OS's if I remember correctly.I expect the exact opposite. 2 cores of the new consoles are reserved hardware, so games will have access to 6 cores 12 threads at most. Given the work to get game engines to use 6 cores already done, I believe we will see games continue to use 6 cores, MAYBE 12 threads, and continue to not take advantage of 8+ cores as there is no financial inentive to do so unless you are making a PC exclusive game.
The Xbox 360 had 3 cores and 6 threads, but games didnt start using more then 2 cores in any significant manner until the PS4 came out in 2013.
There is also the issue of games not inherintly being a multi threaded application. Throwing more cores at the issue will not always mean they will be used. Even today we still see 1-2 threads being loaded way heavier then the other 4-6. The boost another 2 cores will provide under sucha system are very minimal, and this is with engines optimized for 6 very slow jaguar cores. Now we'll have 6 fast Zen cores available, there's no incentive to push even more multithreading VS taking advantage of the 6 cores they arleady have.
