| Zero999 said: why would i expect a 10x fold increase. even the ps4 is only a 4.5x over the ps3, if you count raw gigaflops. the wii was 20x less than ps360 with different architeture. now wii u should be 2x less than nextbox and 3x less than ps4 tops, see the difference? |
PS3 GPU is around 176 Gigaflops.
PS4 GPU is around the 1.8 Teraflops mark.
That's a 10x increase in the main piece of hardware that renders and does all the fancy little tricks on screen alone.
Plus it's capable of much more effects than the PS3's GPU and is more efficient at doing so too.
CPU wise...
PS3 CPU: Around 230 Gigaflops for the maximum theoretical. (Note: No developer has managed to harness that.)
PS4 CPU: Anywhere from 300-400 Gigaflops, I'm basing this on the improvements from Brazos to Jaguar and the doubling of the cores etc'. - x86 based, easy for developers to gain the CPU's full potential.
At most a 2x improvement, Note: CPU's generally don't render graphics due to being serialised in nature where-as graphics are incredibly parallel in it's workload, some smaller framebuffer effects sure.
Ram:
PS3 Amount: 512Mb total. @ 24.9GBps. (That's the faster XDR speed I've listed.)
PS4 Amount: 8192Mb total. @ 176GBps.
That's a 16x increase in the memory amount, 7x increase in memory speed.
Graphically, I would expect a 10x increase in image quality, it's a given, no idea where you pulled that 4.5x number from, it's the GPU rendering all those pretty graphics remember, not the Ram or the CPU.
As for the Wii being a different architecture, that's not entirely accurate, the Wii used the same PowerPC architecture as the Xbox 360 and PS3, so CPU instruction compatability wise it's not all that different.
GPU wise, the Wii used an AMD Radeon (Possible Radeon 9000 series class) but modified heavily, using the TEV pixel shader technology that was in the Gamecube.
Now as for the Wii U vs PS4's GPU...
The PS4's GPU is again capable of about 1.8 Teraflops.
The Wii U's GPU will more than likely be around 240 - 624 Gigaflops (Basing that on the Radeon 6570 and 6450.)
Then the PS4's GPU also has a far more efficient Tessellator, it can render far more complex scenes and models with a minimal performance penalty, the VLIW5 architecture just never managed to be that great from a geometry perspective compared to the GCN architecture and that's just one of many examples.
The sad part is, I've had people yelling at me for bashing the PS4 over the last few days, you really can't win on this forum can you?
