| fallen said: I see a lot of so called spec comparison on places like Neogaf that are incomplete, or extremely biased towards PS4 to the point of being nonsense, so I wanted make a true, unbiased reference. The PS4 will go second and be compared to the X1 baseline in terms of percentages. X1: Disc: 6X Blu Ray Disc capacity: 50 GB HDD: 500 GB 5400 RPM RAM quantity: 8GB CPU: 8 core (6 game usable) 1.75 ghz Jaguar (Plus SHAPE audio chip likely ~1 CPU core of audio processing, +cloud support which we will ignore for now but could offload things like AI from X1 CPU in the future) GPU FLOPS 1.31 teraflops Texture units 48 at 853 mhz Triangle setup engines: 2 at 853 mhz ROPS 16 at 853 mhz Peak bandwidth: 204+68=272 GB/s Peak BW per GFLOP= 272,000 MB/S/1310=207.6 MB/S/GFLOP
PS4: Disc: 6X Blu Ray (+0%) Disc capacity: 50 GB (+0%) HDD 500GB 5400 RPM (+0%) RAM quantity: 8GB (+0%) CPU 8 core (6 game usable) Jaguar CPU 1.6 ghz (-9% raw, -24% after removing 1 core for audio processing to match SHAPE, ignoring X1's cloud capability for now) GPU FLOPS: 1.843 (+41%) Texture units: 72 at 800 mhz (+41%) Triangle setup engines: 2 at 800 mhz (-7%) ROPS: 32 at 800 mhz (+88%) (However, the real world impact will be much lower as 16 ROPS typically enough at 1080P and less) Peak bandwidth: 176 GB/s (-35%) Peak BW per GFLOP: 176,000 MB/S/1843=95.5 MB/S/GFLOP (-54%)
Specs PS4 is superior in: ROPS (+88%), GFLOPS (+41%) Texture Units (+41%) Specs X1 is superior in: CPU (+9%) Geometry setup (+7%) Peak bandwith + (55%) Peak BW per GFLOP (+117%) Specs they are equal in: Ram capacity, Optical Disc capacity, Optical disc read speed, Hard drive read speed.
There you have the complete picture of baseline specs, subject to countless other variables we know nothing about...
From a high level, PS4 has a stronger GPU while X1 has a sigjnificant edge in peak bandwidth, and a slight to moderate advantage in CPU, which could grow if developers begin to leverage the cloud in the future. The disc read subystems and RAM quantities are identical. |
xbox one does not have a huge advantage in bandwith. The fact that the ES ram doesn't even make up 1 PERCENT of the total ram. And many devs have still said that it's diffiult to use. So this is a very slanted view.
So to derail your whole argument, while using a similar argument to your peak BW per gflop argument. Lets don't average bandwidth per mb. Total mb on x1 8224. amount of 66mb/s ram 8192, amount of 192gb/s ram 32 (core gpu clock doesn't up EVERYTHING btw), 66.49 gb/s. And no, I know that's not what the real bandwidth is prabably, but adding them together is probably a more stupid and simple idea than mine.
And let's look at the games, and move away from tech. KZ shadow fall runs at 60fps 1080p in multiplayer, knack runs in 1080p 60fps, drive club 1080p 60fps Xbone, ryse 900p (fps TBD), forza 5 1080p 60fps, killer instinct 720p 60fps, dead rising 3 "dynamic res" having trouble pushing 30. 3rd parties, the devs of AC4 said they'd pick the ps4 version over xbox one in an interview, watchdogs 1080p 30 fps on ps4, ad 30fps res TBD. The only game that might be equal is bf4, but even the res might be higher on ps4, they said they're "trying to get the same resolution." So yeah, unless all the devs suck at programming for the xbone, I'd say ps4 is more powerful.
