I'll just re-post what I posted last time some bullshit developer claimed that their game "needed" an "8-core" CPU.
Also, I feel it worth mentioning that any game that will run fine on a GTX 460 or HD 6850 (mid-range cards from 2010/2011) but requires a high end I7 (2011 "sandy bridge or later) has to be CPU-bottlenecked in a way we've never seen before [http://www.tomshardware.com/reviews/build-your-own-budget-gaming-pc,3780.html].
Original thread I posted it in [http://www.escapistmagazine.com/forums/read/7.846654-Watch-Dogs-PC-Requirements-Recommend-8-Core-CPU#20877690]Under_your_bed said:I doubt it. I doubt it very much.Alex Co said:Does this mean eight core CPUs will be the norm for AAA PC games this generation? If so, will you rather buy the same games on consoles instead?
First of all, it seems that both Killzone Shadowfall [http://www.eurogamer.net/articles/digitalfoundry-ps3-system-software-memory] and InFamous: Second Son [http://www.gamepur.com/news/14201-infamous-second-son-used-ps4s-45-gb-ram-6-cpu-cores-only-comparison-screens.html] only use 6 of the PS4's 8 CPU cores for gaming, with the other 2 reserved for the OS. The same appears true for the XBOX one [http://kotaku.com/the-five-possible-states-of-xbox-one-games-are-strangel-509597078/all]. So really, there shouldn't be any benefit for having more than 6 cores, as any half-decent modern CPU can run windows in the background effortlessly and won't need an extra 2 cores for windows in the background. I've got an I5-3570K at stock settings, and the background tasks of windows and internet surfing almost never causes my CPU usage to crest above 10% in task manager.
Secondly, this never happened last generation. The XBOX 360 had 3 hyper-threaded CPUs [http://en.wikipedia.org/wiki/Xenon_(processor)] and the PS3 had a 7-core "cell" CPU [http://en.wikipedia.org/wiki/PlayStation_3_technical_specifications]. Yes, admittedly, unlike current gen-consoles, these weren't x86, 64-bit CPUs that could be easily ported directly to PC's. But with each console being able to process 6 threads of computing simultaneously, you would have expected them to cause games ported to PC to require more cores over the course of their lifetimes. Nope. As late as 2012, A tom's hardware benchmark of CPU-demanding games found no reason to get a weak quad-core CPU over a slightly stronger dual-core CPU. [http://www.tomshardware.co.uk/gaming-fx-pentium-apu-benchmark,review-32368-10.html] It wasn't until 2013, with a new suite of CPU-demanding games, that they found that modern games were more suited to quad-core processors [http://www.tomshardware.co.uk/gaming-processor-frame-rate-performance,review-32628-9.html].
2012 test suite
2013 test suite
If we compare the two graphs, we note that while in the 2012 Benchmarks, the dual-core pentium G860 clearly beats the quad-core FX-4170 and falls just below the quad-core Phenom II X4 980. However, in 2013, the G860 falls to near the bottom and is soundly beaten by both the FX-4170 and Phenom II X4 980. As most of the games which caused this reversal were released in 2012, we can therefore reasonably assume that it wasn't until around 2012 that games began to take advantage of more than 2 cores, which was towards the very end of the last console's life cycle.
So, in a nutshell, I fail to see how an 8-core CPU is going to be a vital advantage in future games. If the last generation is anything to go by, it seems that consoles have almost no effect on the number of CPU cores that PC games require. And even if the more PC-friendly x86/64-bit CPU cores of the new consoles allow for more direct ports, with the exact same number of cores, it doesn't seem as though games made for them will need more than 6. I don't see MOAR CORES becoming the new big thing any time soon....
