This just got posted a few minutes ago. They are comparing Zen with broadwell-e and Skylake 6700K. I'm excited about Zen.
SourceFirstly, one of the bigger deviations from previous AMD microarchitecture designs is the presence of a micro-op cache (it might be worth noting that these slides sometimes say op when it means micro-op, creating a little confusion). AMD's Bulldozer design did not have an operation cache, requiring it to fetch details from other caches to implement frequently used micro-ops. Intel has been implementing a similar arrangement for several generations to great effect (some put it as a major stepping stone for Conroe), so to see one here is quite promising for AMD. We weren't told the scale or extent of this buffer, and AMD will perhaps give that information in due course.
Quad channel has always been reserved for servers and that includes Intel (X chips are effectively unlocked Xeons sold at outrageous prices).Originally Posted by jarble
Looks like no quad channel ram but otherwise a very solid showing from AMD. Sill have to wait for the real reviews but If it has the right support (pcie lanes usb 3.1 etc) I may be on board to replace my ageing system. The other big question will be MB support as talked about here With intel cpus almost always getting more/ better MB's.

Finally, hopefully more affordable "5960x"s for everyone.
We've had 4 cores for so long, and the closest cheapest higher core count is something like 5820k for $299 if you were lucky to get it at Microcenter, but 8 cores has always been out of reach.
Hopefully.... it's a little more in reach, around $650ish for zen 8 core?
If it has the performance to come close to a 5960x, I guarantee you AMD will price it near a 5960x. AMD needs all the financial help they can get.Originally Posted by kevinf

an 8 core monster should be ~ $400
Agreed its going to depend on where it really sits with the intel lineup. If its faster than a 6700k but slower than a 6900k they are going to price it correctly.
I think I read somewhere that AMD was planning on trying to undercut Intel's mainstream lineup with the first Zen CPUs, that would put the 8 core at $500 max, twice the cores/threads for only ~$100-150 more (compared to an i7), that would be undercutting Intel fairly well while still being able to make a decent profit (I would hope anyways, not sure the price to produce these 8 core variants).
I can forsee the price been anywhere from $100-300 cheaper the 5960x if performance is equivalent. Though it is true, they could use the financial boost, with a lower price, they would be able to push a lot more units than what Intel is doing, thus giving a similar financial boost.
This is even better than what I was thinking, and I hope you are correct.Originally Posted by LeadbyFaith21

The part about outrageous prices only is not true. A 5820K or a 6800K Skylake/Broadwell E processor can be had right around $400 that supports quad channel ram.Originally Posted by Liranan

The price where the 5960x is at actually has very little do do with how a Zen eigjt core is priced. The Zen chip is likely at least 15% slower, nor does AMD have anywhere near the brand regocnition Intel has. Then there's also the fact that Intel has completely out of the production factor and rather solely on demand. If what I suspect is true the total Zen BOM is far lower than of a comparable Intel chip and they can drop the price a fair bit to increase demand and give more people a reason to upgrade. Profit per chip is only half of the equation, the sales amounts are equally important.
Gaming is probably going to be one of the places where Zen isn't going to be that much more attractive than what's availabe, or at least the high core count chips. Intel is very likely to maintain a ~10-20% advantage in both IPC and clock speed.

I'm a bit more optimistic about Zen than what I was before. The core and cache layout look good and 2LD+ST/cycle is a bit better than expected. The biggest variable for success is the clock speed.

A 6800k would be a regression for me in PCIE lanes and the 5xxx is not enough of a ipc upgrade to warrant the change. Yes i know I a picky dude
$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.
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.Originally Posted by formula m

"The demonstration used the multi-threaded Blender rendering application on two similarly configured PCs. One featured an engineering sample Summit Ridge chip, while the other featured a new Intel Broadwell-E Core i7-6900K CPU. 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
At 3GHz in an AMD controlled test.
