    Wait, so, they're going back to making the same daft mistakes as with the (ultimately dead-end) Pentium 4? Or are they anticipating memory getting even more "bursty" (ie the overall lag between each squirt of data not improving much, and so becoming effectively worse vs the CPU's work rate, but each squirt delivering much more data in one go), and code being optimised more for that in future, so there's a need - and a genuine one, this time, that's not as easily solved by dual channel architecture, more efficient memory management hardware, better cache structure and DDR2 - to prebuffer many more instructions and operands to keep the well from running dry?

    (maybe it might even become a thing to prebuffer both paths out of a branch, if they happen to fall within the same simultaneously-fetchable chunk of memory, which would A/ need, and make full use of a longer prefetch queue, so long as it could be tagged and handled properly, or if the "outer" stages of it were twice as wide as the inner ones; and B/ not suffer anything like the same massive performance hit as the P4 did from an incorrect branch prediction and subsequent queue flush...)

        Where did you get that rumor?

          The rumor was started as speculation on a few factors. 1. Zen's IPC and clock frequency are both comparable to Intel offerings and are matching performance of more expensive models in leaked benchmarks. (this part still is yet to be completely confirmed though) 2. Tech writers are predicting AMD will have an offering as low as $150 to keep its hold on that segment and 3. AMD has stated it will not be making Zen processors (CPU) with fewer than four physical cores.
