I doubt XV will bring any significant improvements to IPC, so Zen sounds like it'll be just a bit slower than Haswell in the best case.

Also, dropping CMT will also mean no more handicap in multi-threading, so at least they have a really good chance of improving multi-thread performance over Intel.

If Zen has just under Haswell in single thread and they can push the multithread to be better.. that would make a very competitive chip especially with dx12 vulkan

If that is just for integer it's okish if it is for both floating as well as integer then it is extremely good news.
But yeah I'm excited too bad it's more than a year away.

40% over Excavator we are not talking 40% over Bulldozer.

"Competitive high performance CPU"
Also he just said
"Pedal to the metal"
Said that a day or so ago about Zen wink.gif

Also 390(x) in "the next few weeks" or maybe just a HBM card of a lower tier though doubtful.

Well, Geekbench is a mixed test. And Zen's improvement may not be even across different workloads. I'm hoping it's skewed towards a big FP improvement, but we won't know until the chips launch in 2016.

Not seeing K12 until 2017 is somewhat annoying. No android tablets any time soon.

People should also remember that slides like these are going to present a rosy picture and that we don't know anything about clocks yet.

Yep, if we're lucky it's a clock by clock, thread by thread comparison. If we're not, it's a full package comparison.

I only understood why my Mother had been so fond of the adage "Bread will always land butter side down" when one day, on a whim, I asked her if I had been born with such a lumpy head or if it came later. - Me.
