Forums - Microsoft Discussion - TRUE XB1 vs PS4 spec comparison

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.

LOL at the bandwidth's and ROPS, this sounds like damage controlling rather than facing some simple facts.

Edit: Why on earth is this thread just in the microsoft discussion when it supposed to be in the gaming discussion section.



So since when the bandwidth for both ESRAM and DDR3 of XBOX One can be lum sum as one total bandwidth,
guess i have to get back to college and check this out with my Computer Science lecturer.

No you want to ask computer or electrical engineering undergraduates or professors cause they know more about digital electronics and processing than most of the computer science graduates.



Oh, so now it's MB/S/GFLOP, I see! You know that South Park episode where they measure penis sizes and keep on changing the formula until everyone has a big one? Kinda reminds me of that.

Also, that bandwidth of Xbone is impressive, but what will happen in the crazy case that a developer needs more than 32 MB RAM? I know, I know, it's hard to imagine to use such a massive amount of data, but just what will happen theoretically?

It's pretty simple in the end. There are some minor differences, but after all, they are both using the same architecture. PS4 is just faster, end of story. The cloud won't do jack shit, I can tell you that. That said, the graphics of the Xbox One will be good enough. But please stop making these silly threads where you try to make the systems look even in hardware. It's getting ridiculous. No, to be perfectly honest, it already became ridiculous a long time ago. If you care THAT much about specs, just get a PS4.

You need to remove 10% you for Kinect but keep that damage control coming. And 1 core for shape lol again shape is mostly there for Kinect.

The Peak BW per GFLOP is useless.

Some compute tasks aren't bandwidth sensitive, whilst others are, some compute tasks are latency sensitive, whilst others aren't.

Thus, even though the Playstation 4's "Peak Bandwidth per Gigaflop" is lower, developers can set aside non-bandwidth sensitive compute tasks on the extra GPU resources that are available.

Besides, if we lived in a perfect world, Gigaflops would be the end-all of performance metrics, just unfortunate that GPU's and CPU's as well as Game engines deal with math other than floating point, making it a pointless affair.

Just a question. How useful do you think that 32mb ESRAM will be in trying to close the gap ? 



Interesting, would you mind pointing to your sources? It will help answer some questions.

And I see it's already brought out some misinformation.

Curious, why are you pulling out one core on the PS4 for audio? It can also do some with 4 CU's of it's GPU (I know) and does have a little audio chip.

I am sad for the loss of innovation, all gaming and gamers mourn the pushing back of the future to another time.  The ice cream may be melting.  E3 Save us all!

So.... You are upset that most spec comparisons are biased towards the ps4, so you make a spec comparison that is biased towards the x1... Yep, nothing hypocritical about that..
