Clock for Clock it's faster than an AMD FX-8150. That is a 3.8 Ghz a10 is faster than a 3.8ghz fx-8150 per core.

Sorry -- let me clarify -- I meant to say that the Phenom II line (including Llano) is faster than bulldozer and Trinity, clock for clock and core for core.

So the Phenom II line (previous generation non-APU) is faster than Bulldozer (current generation non-APU), clock for clock, core for core, and Llano (previous generation APU) is faster than Trinity (new release APU), clock for clock, core for core.

Yes it's true the Phenom II has higher IPC. Trinity has higher clock for clock performance than Llano from what I've seen though.

The Phenom II vs A10 is very close clock for clock. The a10 is a bit slower at the same clock speed.

However it's hard to find a Phenom II X4 clocked above 3.4 Ghz stock for sale these days. The a10-5800k comes @ 3.8 Ghz and has turbo mode of 4.2 Ghz when you aren't using all the cores (which MAME typically doesn't). If not overclocking I'd expect the a10-5800k to be faster than the Phenom II X4 965 Black Edition. There's also the advantage of having faster memory, etc. available for the new FM2 platform. For some tasks the benchmarks actually show the a10 beating the Phenom II at similar clock speeds due to those factors. I'd be interested in seeing MAME specific benches, but I doubt there are any yet.

The next A-series chip is currently slated to use FM2 as well giving an upgrade path next year if desired. The downside is the a10 appears to currently cost about $30 more...but hey if all you're doing is MAME you don't need a video card with the a10.
