It's weakest because they come out first (first quad, but at 40, 6 months later beat by 28nm...well duh).
This will be beat by stuff in sept, but again, those will be too late to get into a device most likely or on the cusp for xmas etc (note Qualcomm whining that nv just came first...yeah, that's the point to get design wins for a certain date). Since exynos5 in my dads nexus 10 does pretty well at 2560x1600 but just a tad weak in gpu this should be better especially since they actually get tegra games optimized and it looks like it should be 25-30% faster than exynos. I expected a 48core (4x current). It looks like they actually aimed at apple not current exynos/snapdragon pro which are underpowered for this res. Nexus 10 should have chose apples res and it would have been excellent. This should make a decent 10 at 2560x1600 finally. I hope google is tooling up for a nexus10 rev2.
It seems they took the die shrink and either grew the chip (to get another 24 cores) or figured out how to keep the die size and fit more in it. I'm guessing though, this is over 81mm but we'll have to wait and see. I expected the die shrink to allow 4x the current 12 with no power loss at the same size or so (since they went quad core first, and left gpu weak). This goes further than that even assuming they are the exact same gpu cores from tegra3. Just 6x the tegra cores would make it in A6 league or so, which would make it VERY attractive for all but apple. Nice. If they are better cores it should be ABOVE A6x.
IF this slide is true (big if, I really expected 48gpu, a simple quad of the gpu), this will rock for a while and make it into a ton of devices for xmas (from july products on probably in volume). I like the fact that they release like this, to make it into Aug->xmas devices (like the nexus7) with no chance of missing that boat. I think samsung upped the exynos6 date to try to get in more xmas stuff also. There are NOT enough of the nexus4/10 and they needed to land their chip a good 2 months earlier to get more production/designs for xmas, which it looks like they're doing this time. Good times ahead...Here comes the nextgen SOC war
I'm hoping NV speeds up just a bit and gets the Tegra4+ for those xmas devices mentioned above. The first model makes it into early-mid year stuff, but I'm hoping 4+ makes it for xmas though I'd have no trouble buying a nexus10 with this 1st gen if it's really 72core as that puts it at or above apple.
If this is wrong and it's 48core though, it's just a exynos5 type and isn't enough for 2560x1600 (perhaps why they made it 72...they saw and recognized the issue with exynos5).
