AMD Confirms Key "Summit Ridge" Specs
AMD CEO Lisa Su, speaking at the company's Computex reveal held up the most important CPU product for the company, the new eight-core "Summit Ridge" processor. A posterboy of the company's new "Zen" micro-architecture, "Summit Ridge" is an eight-core processor with SMT enabling 16 threads for the OS to deal with, a massive 40% IPC increase over the current "Excavator" architecture, and a new platform based around the AM4 socket.
The AM4 socket sees AMD completely relocate the core-logic (chipset) to the processor's die. Socket AM4 motherboards won't have any chipset on them. This also means that the processor has an integrated PCI-Express gen 3.0 root complex, besides the DDR4 integrated memory controller. With the chipset being completely integrated, connectivity such as USB and SATA will be routed out of the processor. The AM4 socket is shared with another kind of products, the "Bristol Ridge" APU, which features "Excavator" CPU cores and a 512-SP GCN 1.2 iGPU.

I haven't seen any mention of quad channel memory for the 8 core+ flavor...I would HOPE that this is the case. I don't find it entirely useful, but would be nice to know it's there.
I think clocking/OCing ability will be their make or break. We all know intel is tapped out, hopefully Samsung has a trick or two to make 5ghz an easy reality. If they're aren't clocked high...then the IPC increase doesn't matter.
I'd love to see Zen finally giving Intel some real competition, especially with 8 true cores, but I remain sceptical until I see a full review from a respectable tech website like TPU.
Woah? Seriously? And how much would chipsetless boards cost?Ignoring what IPC is (you are wrong about that too), flops is VERY precise measure of what how many floating point operations a chip can do.
It alone is indeed not enough to predict performance, but when comparing 2 chips on the same architecture, it's pretty good.
Also, when having big differences such as 2 vs 8, you can be sure the former is much slower than the latter, no matter which vendor/architecture.AMD's Jim Taylor said "we are as close to Intel as we've never been", so nope, definitely not in high end.
I couldn't care less about high end though.
So, 1.05*1.19*1.03*1.11*1.033 = 1.4756 => 47.56%, Skylake is not 20-30% faster than Broadwell, so if Zen is genuinely 60-70% higher IPC than Bulldozer then it's going to beat Skylake clock for clock (in Cinebench) all day long.
OFC this is all Napkin math using Cinebench IPC comparisons...
i mean 4 faster cores with 8 threads or 8 slower cores with 16 threads reminds me of a place we have been before xD
1.05*1.19*1.03*1.11*1.033 = 1.4756 => 47.56%
AMD can't just say, "well, we have slightly lower performance so we'll sell for less", because Intel has everything covered from ~$60 to the newly released, obscenely priced Broadwell-E. If they don't have better IPC, is AMD going to slap a beefier IGP and call it an alternative? Again?
Sure for thread intensive work but that's a small minority of users. So, if Zen matches what the like of Skylake can do, that would be good. That being said, does Zen not come in a package that can be added upon to make multi threaded monsters (like uber skulltrail mobo's?).
I'm just pissed we wont see Zen till 2017 (probably, going on rumours so far). My patience will run out by November.
EDIT: I need to learn how to type - so many edits in this one bloody post.
However, when I upgraded from a P4 Northwood 2.8GHz (3.5 o/c) to an A64 3800+ the gaming framerate shot up It was on an Abit AN8 Ultra mobo too. :cool:
