When I worked to build my computer last year I first thought of an AMD based unit, but then I noticed they have not made a PCIE 3.0 slotted card. Why? They make 3.0 cards but not motherboards! In the end I wonder is there a method to this madness? Why is now the new AM1 chipsets even they still have no such slot are they awaiting 4.0 or something and skipping a generation? It makes me wonder if they want to lose to Intel or if the market they now want is for lower end PCs.

Because high end graphics cards can't even take full advantage of PCI Express 2.0 x4 (most of the time) yet

And another read: http://www.anandtech.com/show/5458/the- ... g-and-msaa

Also AM1 is, for lack of a better word, bottom tier. There's no point in pairing a high end card with it because the CPU will bottleneck it.

Actually Maximum PC noted in tests they can saturate the lower slots. The x8 interfaces are saturated by modern GPUs. Now the x16 is not yet but it does mean in any motherboard I use from AMD I have to get less for the card I bought in terms of performance running it in 2.0 mode.

It depends on the load and what you're doing, but considering the article I linked is still a good representative of what's out there and what's being played, I'm still going with that. Among other things.

My point is how long do they plan to wait? Eventually it may results in them falling behind someplace. I ended up going Intel cause I wanted PCIE 3.0 so AMD loses sales on it. Now obviously AMD isint concerned with losing one enthusiasts business but wouldint it be smart to even make one higher end chip set with the PCIE 3.0?

Actually AMD does have PCI Express 3.0 boards, but they're all FM2 boards.

Also because AMD appears to have given up on the high-end CPU crowd. I honestly think this is why they're leveraging Mantle so damn hard. If they can't compete with Intel in the high end and they want the sizable gamer market, lower the CPU performance bar and make Intel's offerings more expensive for gaming purposes.

ok then that I suppose makes more sense even if i think it's dumb as a plan. But yeah it would explain why they push mantle as hard as they do now. They want to try to optimize so they can clsoe the gap without having to win in making better CPUs.

It really is not making sense why not so many PCIE 3.0 available.
