AMD Phenom II X6 1100T Review: The New Six-Core Flagship

Test Systems And Benchmarks

We’re concentrating on the new Phenom II X6 1100T flagship in our benchmarks. While the Athlon II X3 455 and Phenom II X2 565 are interesting processors, the 100 MHz speed bump probably won’t show much of an improvement over previous tests that we’ve performed. We are interested in seeing if the new top-of-the-line model can be overclocked higher than the 1090T, though. To this end, we've equipped our test bed with a Cooler Master Hyper 212 Plus CPU cooler.

We’re including the Phenom II X6 1090T and 1075T for comparison purposes. The Phenom II X4 970 and Core i5-750 are also present to represent similarly-priced quad-core performance. Finally, the Core i7-920 shows what the starting point of Intel’s more expensive high-end offerings can accomplish.

Take note that the Core i7-920 sample we have on hand is an engineering sample with a lower memory multiplier than the retail version. This will hurt the Core i7-920 in some memory-dependent tests, but for the most part performance should remain comparable to the commercially-available processor.

    I wish Intel would do something like this for all (or at least most) of their processors.(the speed bumps with same price model)
  • fstrthnu
    A pretty good effort from AMD, but Sandy Bridge is only 2 or 3 months away by now. Of course, this is just a stopgap measure till Bulldozer comes; still, when AMD is only just catching up to Intel in terms of stock performance NOW (even though it has slightly better value)...
  • sideshowbob32
    Great article I just ordered a 1090T for m old am2+ set up, I look forward to it and this article makes me want it more!! Glad to see amd is doing great.
  • tacoslave
    im gonna wait for bulldozer
  • stingstang
    AMD is most certainly not doing great if they have to rerelease all their chips. Here's what happens: They make a batch of chips and sell them all as 4 core processors at X speed. The ones they don't sell or are returned go into stress testing. Those batches are divided in to x2 or x3 piles depending on how stable they are with which cores enabled. The winners of the tests get promoted and branded as new, faster chips with x+100 MHz. The process then repeats.
    Now if you'll look, their third iteration of this process still doesn't match intel's entry-level i7 processors. It's just embarrassing is what that is.
  • Could this be any more unremarkable or unnecessary a product? Might as well grab an i5, or one of the existing X6s, or wait for SB, or Bulldozer... this is just pointless.
  • buzznut
    I'm waiting as well I think. I'd have to upgrade my mobo to run a X6 anyway since Biostar chose not to support it with my current board. I think the 1090T is a great value at $230 though. Pretty sweet.
  • sudeshc
    thats more like it, increase those stock speeds and the we will have more chance to to get even more performance by overclocking :D
  • FunSurfer
    It would be nice to see in the gaming benchmark games that have intensive use of all the CPU's cores like GTA4, BFBC2, RFG (@ large building destruction).
  • dEAne
    With this data Sandy Bridge will not put pressure on AMD it will kill it. I think the only thing left for AMD is to lower the price much further.
