Just thought I'd share http://www.techpowerup.com/131580/AMD-Orochi-Bulldozer-Die-Holds-16-MB-Cache.html

That's a pretty large increase in cache, even compared to what Intel has done in the past. I wonder what this'll mean for performance...

Depends. How much cache is useful largely depends on the workload. That why server chips often have more, is that the kind of stuff they do usually can make more use of it. So it'll depend on the apps you run, and also just on how the CPU deals with data.
I would presume they are putting it on because it is useful.
I wonder if the huge cache is only for their server chips. After all, they're still only 32nm, so that much cache would definitely increase the die area and lower profit margins. Makes sense in a high-margin, low-volume market but not when the opposite is true (desktop market).
Doesn't Intel swear by 2meg per core?
