It appears to have been another paper launch with no actual product. I was looking at a cpu comparison website the other day and noticed that it did not show a benchmark for the Intel Corei7-3520m, but rather the 3525m. I checked on Intel's website and it doesn't exist, yet fudzilla.com said it did in Q3 2012. So what happened to it? Was it never released?
Mark this as best answer so people can see all in one!
