Out of order, 1 MB of cache. I'm not too familiar with the GPU. Xbox360 most likely has higher performance, and this is why I was hoping they'd use as "beefed up" (no regard for power consumption) Tegra 4 instead of a beefed up Tegra 3.
Not sure what DirectX version Xbox is using but I know PS3 graphics are usually considered higher quality, and they're only using a slightly modified version of OpenGL ES 2.0, which is what Tegra 3 supports, too. Tegra 4 will support GLES 3.0, and they might surprise us with support for the full OpenGL 4.3, too, especially if built with Kepler DNA, but I'd say the chances are less than 50% for that.
But anyway, I think the comparisons with Xbox are rather pointless and people who do it "don't get it". Does the Wii really need to be compared with Xbox in performance? It seems millions of people bought it anyway.

I read someplace - can't remember where exactly - that AAA PS3 games generally don't use OpenGL ES at all but instead use some kind of more direct access. There's also RSXGL, which implements the OpenGL 3.1 Core API.
