Ryzen Release Thread

Now, as for the rest of the rumor, it’s by no means impossible. AMD is already planning to build a 32-core Ryzen with 8 memory channels (one per CCX). A 16-core device could easily turn out to be a quad-channel part, and that would compete well against Intel’s HEDT lineup.

The one thing I’d caution against, however, is treating this rumor as if its either proof AMD will launch such a chip or that this kind of processor would be desirable to most enthusiasts. First, AMD will be required to cut clock speeds. The more cores you have, the lower your maximum clock is going to be. That’s always been true for server chips from both companies. Even allowing for some variation between product SKUs, higher core counts mean lower clock speeds or similar clock speeds at a substantially higher TDP. Intel’s E7-8894 v4 (24 cores) has a base clock of 2.4GHz and a boost clock of 3.4GHz in a 165W TDP. The E7-8891 v4 (10 cores) has a base clock of 2.8GHz and a boost of 3.5GHz in the same 165W power envelope.

Which of these CPUs is “better” depends entirely on how multi-threaded your workloads are, of course, but the trend holds clear. If AMD wants to build a 16-core Ryzen, even in a 150W TDP, it’s going to have to give up some clock speed to get there. It might make a fabulous workstation chip, but I’d bet you’d get better gaming performance from a different CPU in AMD’s lineup.

Would a 16-core Ryzen punch holes in Intel’s product family? Possibly. There is some concern that by joining that many CCX’s together, the relatively limited 22GB/s of bandwidth between the CCX’s could prove a scaling bottleneck with that many chips to handle. And it’s absolutely possible, even likely, that gamers would see little benefit from this kind of firepower. Games are typically designed to run on higher clocks with lower threads; few platforms can saturate threads to the point that they count for more than raw clocks.

Still, it’ll be interesting to see if this rumor proves true. Depending on what AMD pulls off, it might be able to regain market share, even at the highest end of the non-server market.
