Okay. So AMD claims that Zen will have a 40% increase in IPC over Excavator. It is generally assumed by pessimists that the 40% number refers primarily to FPU-heavy workloads (Cinebench R10 being an example) where Construction cores are considered to be weak. The general idea is that Zen will have more execution resources per core versus BD/PD/SR/XV's modules.
If somebody could show you Cinebench R10 numbers for Carrizo (no throttling, no turbo, just steady clocks), and then we multiplied those numbers by 1.4, would you accept that as a probable performance reference point for Zen?
You're really latching onto Cinebench I see, even after I said I threw it out there for the hell of it.
Let me just be as clear as I can be so all the AMD supporters and fanboys get it, for my own personal consumption, then I'll tell you how the mind of every gamer I know or grew up with works.
For me personally:
Whatever AMD releases has to be at least equal to whatever Intel can offer me at the time in terms of performance and, within reason, power consumption. For instance, I recently went to AnandTech's Bench and pulled up the top AMD chip, FX-9590 or whatever it is, and matched it up against my processor, a Core i7 5960X.
It literally dominated every single benchmark. There wasn't a single benchmark that AMD was able to win. Not one. And before everyone goes off the rails crying, you can pull up a Core i7 3960X and see the same thing. Two generations back, Intel's top processor was destroying AMD's best effort. On top of this the FX-9590 was around $800 at release, putting it fairly close to competing against a XX60X processor. But I'll be generous and let you dial it down to a xx30K. And you'll still lose.
For every gamer I know:
Most of the people I know who game are either people I grew up gaming with, playing FPSes or World of Warcraft or EverQuest, and they all have careers and families now. They, like me, care about the best performance they can get. Great example, husband and wife couple I grew up playing EQ with built themselves two new machines for playing Final Fantasy XIV ARR. They used i7-4790K processors and GTX 980s. No AMD in sight.
Some of the younger gamers I know that play DOTA 2 / League of Legends live with Mom & Dad, or are in college with expenses paid for by Mom & Dad, and guess what... Mom & Dad don't buy AMD processors. They buy Intel. They buy Intel because Johnny Knownothing at Best Buy tells them to get this ASUS ROG desktop for Little Timmy, because it'll be able to handle all his school work and he can play a few games because its got a GTX 970 in there.
AMD has to overcome so many obstacles to turn their company around, you'd think they're the reincarnation of Rosa Parks and Martin Luther King, Jr.
They need to win on performance.
They need to win on power consumption.
They need to win on marketing.
It would be great if AMD could manage even one of those... release a 20% slower than Intel's top-end parts, but consume 30% less power. That'd be a home run. Release a part that performs within 5-8% of Intel's top-end parts at the same power consumption. That'd be great. Marketing isn't an option because they don't have the cash to compete against Intel.
Finally, everyone trying to hem and haw and massage whatever numbers they can to make Zen look attractive, you're wasting your time, because all of you consistently try to compare Zen against
what Intel offers right now.
Zen is a year away. If you think Intel will sit on the sidelines and let AMD catch up, you are sorely mistaken.
