AMD Announces World's First x86 Quad-Core System-on-Chip

Tom,

The new Jaguar cores will have 15% better IPC, and 10% higher clock speeds. That was announced a while ago.

Going quad core makes a lot of sense too, because AMD can boast they are the first quad-core x86 tablet processor maker, and people really do put a lot more value into that than they probably should.

[citation][nom]Tomfreak[/nom]I am not entirely happy with quad core. Brazos 2.0 are weak on IPC. They should have improve the IPC, not doubling the cores. We still need a low power Core 2 duo/Athlon X2 replacement. Not some underpowered IPC quad core.[/citation]As others have already pointed out, there ARE IPC improvements. In addition, they DO have dual cores available, and with slightly higher clocks than Brazos 2.0. So they will have faster dual cores. They ALSO have quad cores. Clocks might not be quite as fast, but for multitasking and anything that can take advantage of more than two cores (on an x86 machine running Windows there's actually a decent amount of software that does) it's actually a huge performance increase over the dual cores.

The CPU side for Kabini and Temash will see a boost too (IPC, clocks) but not by 50% (except for comparing dual vs quad core, in which case the increase in well-threaded apps will be MORE than 50%.

Richland on the other hand, will probably not increase CPU performance by much... just clock bumps. But a 20-40% increase in GPU performance is nothing to sneeze at, especially as a stop-gap measure until Kaveri arrives.
