| Trunkin said: Really? But its performance in multiplats(namely BF4) is perilously close to an HD7870 rig, though. With optimizations I would've thought it'd easily beat out a Windows HD7870 PC, even at launch, but that doesn't seem to be the case. Why is that? |
Yes, without optimizations it is on par with HD7870. Especially in a cross-platform like BF4 they just aren't making those optimizations at this point.
To make those optimizations, they would need roughly 10x the number of GPGPU command usage as the Xbone, and clearly they are just
not going to make that amount of platform specific optimization with unique codepath (that even most PCs can't handle) at this stage in the game.
With Sony's approach to this (ACE), they have chosen an approach that IS in line with general state of the art graphics programming though,
even if the # of ACEs is beyond anything seen in anything but top of the line PC GPUs, the same sorts of programs can and are written for ACEs,
so there is a larger number of programmers out there ready and able to make use of that, and what they learn for PS4 will be applicable to future PC gaming.
PS4's unified memory should further enable synergy between ACE/GPGPU and threads runnin on the CPU, along with the general benefits of fixed hardware,
which XBone also shares albeit with reduced CUs, etc., and informed opinion seems to be that Sony's API is more powerful than MS'.
