Still waiting on a replacement for my Phenom II x4 955 ... I love how they added more cores in the last 4 years, but the single threaded performance has barely grown to the benchmarks I could look up. Lets just hope their high dense library lib, and other enhancements will save speed-up their single core speed. Then they get more money. Why am I waiting for AMD, and don't I buy an Intel? I'd like to support competition in the market. If I'm misinformed and the new CPU's ARE faster, give me a poke.

The latest out of Tom's Hardware[1] seems to indicate that the combination of improvements in threading and modest improvements in the recent CPUs adds up to appreciable gains vs. the old Phenoms. If you're laser-focused on single-threaded performance, steamroller is probably the one to look out for. They claim 30% improvement in ops per cycle.

  Oo new review I didn't see yet: 12% increase, but since I'm @3.2Ghz, that's a 50% increase! Juicy. And yes my single-threaded performance is the one I focus on, because the multi-threaded things, I can wait on :) Thanks for the info.

    Ok, then I suggest you sift through more closely. More and more apps & games are leveraging multi-core (more than most people realize), so the charts in the link I included are an amalgamation of single-threaded and multi-threaded programs, which is how Tom's tries to put together their "real world" indexes.

    3.2? My FX-8320 runs at 4.8ghz. Even if single threaded isn't improved, the headroom for a higher clock is there, thus giving overall better performance.

      But you are probably pulling 160+ watts do accomplish that. On modern Intel parts, you can push 4.5 around 120 - 130. That means significantly less cooling requiremenets, so you could stick the chip in a smaller chassis, etc.
