| Egann said: I expect the XB1 couldn't even use GDDR5 even if you dropped it in. Reading the fine print, the PS4's processor is ever slightly faster, so the additional throughput would be irrelevant for a processor which wasn't designed to use it. The unified memory pool will definitely make the PS4 attractive to devs, but it means this generation has some very odd choices. GDDR5 is not quite as good as GDDR3 for OS and CPU use, so if you really want to push the envelope of the CPU for an enemy AI or something, your best platform choice is the Wii U, which has both GDDR3 memory and CPU cores with significant caches. If you just want to mash X to compile, the PS4 is the no-brainer choice. Sony really did a great job on streamlining development, which I'm sure is why they focus so much on Indy stuff: their console is no question the best for indy developers. I imagine the XB1 will be the graphical powerhouse of the generation between the eSRAM and cloud computing. I just wonder with graphical diminishing returns if that means anything this gen. |
You're right on that you can't just "drop" in GDDR5 memory with the Xbox One, the memory controller (Which is part of the CPU these days) needs to support it, hence the entire APU would need to be respun in order to accomidate GDDR5 memory.
As for the PS4 CPU being "slightly faster". - Well, DDR3 has 20% lower latency over GDDR5 (10ns vs 12ns), so that's going to be a slight (And possibly only?) advantage the Xbox One has over the PS4, which should benefit the Xbox's CPU performance, especially when there is a cache miss.
In the end though, it won't matter, the PS4's and Xbox One's CPU's are incredibly slow to begin with, the advantage the PS4 will have is that it can offload some CPU tasks onto the GPU.
Also, I think you meant DDR3 not GDDR3, there are some differences between the technology.
