    If deeper pipelines were better, AMD's FX series would easily beat Intel's Core series processors and Intel's NetBurst architecture wouldn't have been replaced by Conroe.....or been slower than AMD's K7 and K8 architectures. Fact of the matter is, shorter pipes provide better performance. Shorter pipelines mean instructions complete faster.

    Then the main idea is just keeping all compute cells busy using the pipelining and keeping the pipeline as short as possible?

    Putting a gpu inside of a cpu may have a similar reason then? Shorter ways, fewer stages between two?.

    Maybe thats why Nvidia will add stacked dram in GPUs?

    Then total length of data pipes between cores are important if we were to add more cores?(maybe some optimization algorithms can be used here? Like "simulated annealing" to find a golden geometry of cores and best "core to communication length" ratio?)

    cu seems more "compute units" than cpu for me, so i guess that first picture is a gpu.

    By the measure of CU, this would have 8. Also, long pipeline, BAAAAAAAD!

    What is your problem? Stop flaming. I was correcting someone that said 3.0 wasn't even out yet when it has been.

    If you seriously think 4.0 will not be needed in the path graphics cards are going soon, do some research. Maxwell is going to be pushing 2.0 big time, especially concerning what other add-in cards people are using such as SSD's.

    So go puke on yourself instead.

    Exactly. Less lanes more bandwidth. Its minimizing things is all. Also just like you said the more plugged in the more bandwidth is going to be used. It's not just graphics cards that eat it up.

    Just wanted to say you really butchered how that meme is supposed to be worded.

    Because you can run more devices at higher speed using fewer lanes.

    Wow! AMD is still trying to make new CPUs!?!

    As someone who owns the FX-6300, I won't be signing that petition. Steamroller seems to be the last of the "fixes" for the Bulldozer technology and will hopefully be the end of the line for DDR3. I'm thinking the amount of changes in SR is just a little too much for older chipsets to handle. This is a problem because some AM3 boards work with BD and PD AM3+ CPUs, while I get the impression some AM3+ boards don't all support PD, and it's already a headache for noobs to know which board works with what CPU. It'll also be a pain for mobo devs to update the BIOS. If people want high-end, they're going to shoot for Intel. If they want power efficiency, they still want Intel. The APUs are the only products AMD has that are actually getting them money, and while SR would make an ideal AM3+ CPU, it just isn't worth their time. I'm sure if they make a socket AM4 with Excavator, we might see some interesting results.

    What I think AMD needs to do right now is release an A10 with 6 cores instead of 4. 6 seems to be the sweet spot in your average multitasking system these days, where most games only utilize 4 but the other 2 cores can be used for other tasks.

    I think what he meant was that he doesn't understand why PCIe 3.0 was released in the first place, when 2.0 hadn't been saturated.
