So since the Xbone and PS4 both use AMD's new Jaguar architecture, I decided to attempt to come up with some realistic performance expectations for them. Okay, so basically my first question was, just how powerful was the Cell processor back in 06? In all likelyhood I'd group it with a high end CPU at the time, which was a Core 2 Duo E6700.
So using that Core 2 Duo for the cell, I then looked up the benchmarks for it, it's CPU mark is at 1,583 which was pretty fucking amazing for its time. But now the top end i7's CPU mark is 12,094, so it's roughly eight times faster. The E3500 bobcat CPU only has 2 cores, hell, all off the bobcat CPUs only have two cores, and honestly they suck ass.
A high end ARM chips runs circles around a bobcat in certain tasks, and the %20 increase per core in the Jaguars simply bring the cores up to par with a high end ARM chip in certain tasks. But anyways, the E3500's CPU mark is at a 775.....for both cores, add on the 20% performance increase and it's at around 1,100. So all in all, not that bad especially after considering the CPU has eight cores, and from what I've heard the chips are basically two jaguars glued together, okay, so let's say that the other six cores in the jaguar all scale directly, then the PS4's and Xbone's CPU's mark would be at 4,400 which is almost three times the performance of the cell which is roughly the power of a high end I3 processor.
Of course, this is all under my scaling method which is extremely flawed, but was the only way I could compare them considering that the jaguar chips haven't come out yet. Anyways the CPU's performance should be that of a high end I3 processor, which will be enough to power a dedicated gaming console with a lot less OS overhead.
