here is something i posted on another forum, critiqe and point out my flaws if you want, i encourage it.
i know there is an error, the 7850 M is not comprable to the 460, most are saying its actually comparable to the 420 or less.
the PS4 holds the technological edge over the xboxone
just like last generation.
GPU:
PS4: AMD 7850 M, 1 gig reserved DDR5 system ram, on die
Xbox: same as above, but DDR3 ram, and lower clock rate
for comparison, the 7850 M is the laptop GPU and is as powerful as an nvidia 460. it will be a much less powerful version as they are using a custom fabrication system, and will occupy 2 dies on a 6 die cpu layout. it will feature lower clock speeds and lower discrete units and lower computational power.
CPU:
PS4: Jaguar AMD CPU with the APU ( gpu above ) on-die which eliminates many throughput systems as it is near instantaneous transfer between GPU and CPU as they sit on the same die. this architecture is designed to provide AMD an "in" on laptops, tablets, and cell phones. they will be made on a 6 die CPU layout, with the GPU cores getting 2 die slots, and the other 4 going for the CPU dies. of those 4, one is reserved for the OS, leaving the other 3 open for apps with when running 5.1 or 7.1 sound systems one of the spare CPUs will take the load off the CPU for sound processing leaving less than the full 3 CPUs for the apps.
Xbox: same as above, but again lower clocks.
PS4 is expected to run at a 2.1-2.3 ghz, xbox 1.8-1.9 ghz. additionally for the xbox, they have stated that of the 6 original dies, 2 is gpu, and 2 is the os, and 2 for apps, most likely due to kinect processing getting a dedicated CPU core.
now microsoft is not saying anything about this, BUT sony has admitted that the PS4 will be able to draw blu-ray disc's at their native 1080 without upscaling, but when playing games it will run at a native 1/2 1080 or 960x540 at 60 FPS with upscaling technology. the xbox is running lower clock speeds so it is unknown if they can do the 1080 native for blu-ray and if they are even going to be able to do the 960x540 native @ 60 FPS like the PS4 of it will be a lower native resolution for games/blu-ray.
it appears that the maximum texture size for xbox is 32x32 k, which is a vast improvement over the old xbox texture size of 8x8 k, but nowhere near the standard PC texture size of 64x64, high of 128x128, or ultra high texture size of 256x256k. no word on the PS4 yet.
both will be running a 32 bit OS while maintaining 64 bit hardware other than the GPU which is a 256 bit hardware, while using the extended memory manager system allowing them to address more than 3.5 gigs of ram. they will be running a 42 bit memory manager to allow them to see/access the full 8 gigs of ram.
who comes out on top?
easy, the PC.
