[AT] AMD Zen Microarchitecture: Dual Schedulers, Micro-Op Cache and Memory Hierarchy Revealed - Page 3

post #21 of 233
I am cautiously optimistic. I am nervous many of the "tests" done so far have AMD with a 2 to 1 core advantage, like we have seen from some leaked benchmarks. That being said, on paper everything looks right for AMD. If the IPC is competitive, even if only within 20% of haswell, then we have a huge win for AMD. That is what it takes for me to consider buying one anyway, for one of my machines.

I am rooting red on this one.

Hopefully Zen will drive Intel to make their 6c enthusiast processors mainstream now.

Not much here but the blender test.

Is how I feel about it. I just wanted an actual upgrade from the 2600k for the value proposition. Another 4 core chip was never going to do it. A skylake 6 core could feasibly satiate it, but the product doesn't even exist yet.

$400 for a hexacore isn't good enough. The price has no relation to the manufacturing cost, we've come so far on process technology that a six core with that kind of IPC should be closing on mainstream.

While the Core i7-6900K can run up to 4GHz on some workloads, AMD conducted the test with both CPUs locked at 3GHz."

"This methodology may seem unorthodox to some, but matching the chips clock-for-clock helps reveal their efficiencies. Conducting the test this way also helps AMD protect the final shipping clock speeds of the chips. In the demo, which was performed just once, the Zen finished a nose ahead of the Broadwell-E Core i7-6900K chip."​



ergo: AMD's Zen = clock for clock = i7 6900k
Blender has always run fairly well on AMD CPUs. I stand by what I said, on average Zen should be 10-20% begind Skylake on IPC and clocks, depending on the testing suite. In some edge cases the AMD CPU might well win in.

The point is, this AMD Zen chip offers new tech, new socket & new chipset. And supposedly some new memory bus ..?

And it is efficient.


If Zen's size & price are right, it might kill the i7 for gaming.
At 3GHz in an AMD controlled test.

Intel could sell 8 cores at $350 if they really had to.

They'd still make bank if they sell 6 core at $350.

'Fairly well'

I sincerely hope Zen is on par with haswell at least. We desperately need some x86 competition to light some fire for innovation in IPC.

Right, but what do you think those blender results would be at 4ghz..?  Care to extrapolate on that..?

 

Also, How does a 4970K compare to a 6900K @ 3ghz..? Anyone?
