Nice work AMD.
This. And the best part is this time cherry picking is not with AMD 8 cores vs Intel 4 cores. It is now AMD 8 cores vs Intel 8 cores. thumb.gif
I am guessing single core performance to be between ivy and haswell at least. Time will tell.

I don't think AMD still competes on the single thread mark, but they've got Intel beat on the hyper-threading scalability from past experience with FX chips. I rather have 16 full threads than an Intel I have reboot turn on or off HT.

A bit confused by your comparison? My point mentioning the q6600 was simply saying that a decade old cpu is still more than capable and more than most average consumers will need from a cpu.

Before you answer, AMD has a track record of charging more than the hardware's price to performance would justify. FX9 series for example was something insane like $880.

If they try to put a similar price tag on this ZEN it won't look good. They don't have the credibility to charge that type of premium.. yet.

This statement dates you, completely.

AMD was the leader in CPU performance for years, and did command a premium. They proved, decades ago, they are more than capable in producing a superior product than Intel. Jim Keller himself has a proven record in architecture design as well.

The problem(s) that plague AMD have been money and trying to keep a dead architecture alive. Thankfully Zen was just a big reset button for them. AMD has more than enough history behind them to command pricing, when their hardware justifies it.

AMD pretty much adopted Intel like approach in SMT with Zen. It is simply taking advantage of its longer pipeline just like Intel's architecture. Any stuff from BD arch doesn't apply here.

I am guessing single core performance to be between ivy and haswell at least. Time will tell.

Skylake is 80% faster than Excavator in single thread IPC.

Zen is 40% faster than Excavator in IPC.

Skylake is about 30% faster than Sandy in IPC.

Don't get your hopes up.

If Zen can't do 4.5Ghz and still cost intel prices, then GG AMD.

I fully understand those who were burned by BD wanting to have a healthy level of skepticism regarding Zen performance expectations but I really don't think its unreasonable to expect at least IB parity given Keller's intimate involvement with the design of these chips. The man is a legend and has proven his expertise time and time again. If anything, I would be much more shocked if Zen turned out to be another BD-like failure given Keller's track record.

I am not worried about its IPC, just worried about AMD's ability to optimize the architecture in time to ramp up the clockspeed near the level of comparible Broadwell-E, and how good GF's 14nm FF will end up being.

Well, AMD claimed 40% IPC increase. You can't possibally expect AMD to deliver more than what they claim.
