Its only method for doing these SIMD tasks is via paired singles, and at this clock, it likely doesn't match those two. Though there were benchmarks done by a member of Neogaf (blu) that proves that the architecture of Broadway isn't too bad at these tasks at all, just likely not at the same level as PS360. But it's a processor with strengths in places like GP or integer code, something the PS360 are just terrible at. Calling Espresso "slow" is not fair at all, since it's not designed to do much of those floating point tasks. Probably why Iwata encourages GPGPU, because that could alleviate Espresso. |
Exactly. The CPU may be the Wii U's weakest link, but it's so different from the PS3/360 CPUs that a direct comparison of speed isn't very helpful.
As Criterion said:
"When they first looked at the specs on paper a lot of developers said, 'Well, you know this is a bit lightweight' and they walked away. I think a lot of people have been premature about it in a lot of ways because while it is a lower clock-speed, it punches above its weight in a lot of other areas.
So, I think you've got one group of people who walked away, you've got some other people who just dived in and tried and thought, 'Ah... it's not kind of there,' but not many people have done what we've done, which is to sit down and look at where it's weaker and why, but also see where it's stronger and leverage that. It's a different kind of chip and it's not fair to look at its clock-speed and other consoles' clock-speed and compare them as numbers that are relevant. It's not a relevant comparison to make when you have processors that are so divergent. It's apples and oranges."
