It doesn't match the devkits.
You might be getting too hung up on the kits. They are more powerful than the final consoles. The same thing happened, if you recall, with the 360's alpha kits having FAR more CPU power than the final console.
Do you think MS and Sony would send out dev kits that way over shoot what they are aiming for with their systems? Do you really think these companies work like that?
"Hey guys, start making games on these dev kits that won't look or run nearly as well on our console!"
That would be sound business sense indeed.
They've done that before, actually.
1. Your pc is just running current gen games with a higher resolution and prettier effects. That 2.5 TFs won't be really used until next gen comes out.
2. I'm like 99% sure that Sony's first party will deliver.
What do you think next gen is? lol
More effects, higher resolution.
And yes, Sony's first party is going to deliver.
If AMD really could make their CUs 66% more efficient, they would be pissing all over NVIDIA.
And they'd be selling us the tech, too.
I have no idea. I'm just talking about the efficiency targets Microsoft has for the GPU hardware in comparison to this generation. Throwing out teraflop numbers isn't doing anyone any favors, since the devkits (for both) are rocking in excess of 3.5.
The CPU in the dev kits is more powerful than the final CPUs as well.. so, again. I wouldn't use that as the judge, necessarily.
