AMD Zen Summit Ridge Die says Hello
Over at SemiAccurate they spotted something interesting, it seems to be the AMD Zen Summit Ridge Die as AMD seems to have accidentally outed a rendering of the wafer at its May 12th shareholders meeting.
Summit Ridge is the high-end desktop (HEDT) product that AMD has previously promised to release in Q4 of this year. It’s expected to be the first chip that integrates AMD upcoming Zen CPU architecture. Expectations are high and Summit Ridge may prove to be a make or break product for AMD.
The "Summit Ridge" Zen family will feature a unified AM4 socket with its GPU-equipped "Bristol Ridge" APU counterparts, and feature DDR4 support and a 95W TDP. While newer roadmaps don't confirm the TDP for desktop products, they suggest a range for low-power mobile products with up to two Zen cores from 5 to 15W and 15 to 35W for performance-oriented mobile products with up to four Zen cores.
Each Zen core will have four integer units, two address generation units and four floating point units, and the decoder can decode four instructions per clock cycle. L1 data cache size is 32 KiB and L2 cache size 512 KiB per core. Two of the floating point units are adders, two are multipliers.
See the wafer shot below ...
AMD Zen will get 8 channel DDR4 support and SMT says CERN employee - 02/12/2016 02:04 PM
An interesting snippet of news just before the weekend starts, AMD ZEN based processors will get up-to 8 channels of DDR4 support as well as SMT. The info was spilled by CERN engineer Liviu Valsan wh...
AMD Zen Can Have 32 Cores per Socket - 02/03/2016 09:45 AM
Can .. I wrote 'can have' .. Anyway a leaked Linux patch on LKML.org, first spotted by The New Citavia Blog, suggests that AMD Zen based processors will feature up to 32 physical cores. The patch a...
AMD Zen architecture processors are true quad-core CPUs - 04/29/2015 09:36 AM
A number of slides about AMDs upcoming ZEN APU architecture have been shared on AMDs Financial Analyst day. Zen is the code name for a new 14nm x86 micro-architecture being designed by AMD from the g...

According to the slide, Summit ridge will have up to 8 "cores"
And according to Guru3d, which says each core will have 4 integer units and 4 FP units.. it looks like we could have up to 32 threads on one CPU.
That would be sweet!
They are actually referring to the ALU, AGU, and various FPU pipelines. They do not get their own threads.

Let me explain the picture and why I'm expecting that Zen should perform somewhere at a Sandybridge level.
First I7 2600k has 3.4 Ghz base clock and 3.8 Turbo at 95W .
FX 8320 has 3.5 Ghz base clock and 4.0 Turbo at 125W.
Even if I7 has lower clock is able to outperform the FX in pure speed (like cinebench render) in both single and multi-thread , but by 50% in single thread .
AMD says Zen will offer 1.5x performance per watt over bulldozer .
Well that 1.5x performance per watt will put it just around the older Sandybridge .
Don't understand me wrong, Sandybridge is still a good processor , between a Sandybridge and Skylake clock for clock is no more than 20% difference
I pretty much came to that same conclusion - after long expecting Haswell-like IPC. I based my expectations upon Excavator's performance and even created performance profiles and some process-derived benefits to create a very specific performance range.

If Zen offers only 1.5x performance per watt over bulldozer well damn. Jump from 32nm to 14nm was kind of crap then.
They did talk about having 40+% faster ipc then excavator clock for clock. So that would bring Zen to 50-60% clock for clock boost. Which would bring it closer to haswel/skylake level.
"Compared to AMD’s “Orochi” quad module, eight core die powering the FX 8350, the Zen based desktop Summit Ridge eight core CPU delivers double the performance in Cinebench R15. This means that a single Zen core is in effect equivalent to two Piledriver cores in performance, which is incredibly impressive. "
If that is even close to truth AMD has one good processor incoming in Zen.
Bristol ridge vs kaveri I can understand the 1.5x performance per watt, it's a 28nm vs 28nm other is just Excavator core.

Even if Zen comes with SB performance, with DDR4 and the latest chipsets and controllers it will still be a very viable option. I'm sure many have upgraded from SB not because Skylake or Haswell offer that much more performance but because of all the goodies you get when you upgrade to these modern chipsets.
