That i3 clocks at 3.4 GHz and has 2 Haswell cores (and also runs the OS/background processes).I'm curious about API overhead. We all know that console overhead for things like an API are lower but it doesn't really seem like we're seeing it. Is that i3 Digital Foundry tested with that much faster than what the PS4's working with?
The PS4 has 6 cores (dedicated for games), each one a 1.6 GHz Jaguar.
A Haswell core is probably, clock for clock, about 80% faster to twice as fast as a Jaguar core. Of course this can vary massively depending on workload, but it's a decent rule of thumb. Using that rule, we can say that the i3 is a bit like 2 Jaguar cores clocked at ~6.4 Ghz.
Now, if you simply sum that up you arrive at 2*6.4 = 12.8 "performance units" for the i3 and 6*1.6 = 9.6 "performance units" on PS4. However, parallel scaling is never completely linear in game workloads (though GTAV scales pretty damn well for a game), so you can assume that the actual advantage of the i3 setup is a bit higher. On the other hand, all this assumes that all OS/background workload (for which PS4 uses dedicated resources) is negligible on PC, so it balances out a bit -- though probably not fully.
If you divide 12.8/9.6 you get 1.34. If you multiply 29 FPS (apparently the minimum seen on PS4 after the latest patch) by 1.34 you get ~39. The minimum on the PC is 42, which is a bit higher -- likely due to fewer faster cores always being preferable to more slow ones -- but not off by too much.
What we certainly see and what it all comes down to is that there is no magic thingamajig built into any given PC which prevents it from making full use of its available hardware when properly programmed!
Reporting facts and asking questions isn't flamebait. No, really, even if you dislike the facts or questions.DF please... Using that stupid benchmark for your tests. Also a flame bait PC thread by Alexandros, who would have though.
