AMD Zen To Be Featured Inside Summit Ridge Family of 14nm Processors – Rumored To Feature FM3 Socket Support and DDR4 Memory Compatiblity

The next generation AMD Zen architecture is still undergoing development and will take some time before it’s available to consumers. A report from Sweclockers suggest that the processors which reportedly arrives in Q3 2016 will make home to a new family of high-performance chips known as Summit Ridge. The new processors will be aimed towards both server and consumer markets and will pack true next generation performance over the aging construction cores which started their journey four years ago with Bulldozer.

AMD Zen Featured Inside Summit Ridge 14nm Processor Family

The report posted by the source is pretty detailed, unveiling information we have never before heard of. For instance, we are well known to FX and Opteron series however AMD has planned a new name for their next generation AMD Zen based family and they will be called Summit Ridge. Now it’s likely that it might have some relation with the K12 ARM Core family which AMD seems to be launching in 2016 that is based on their own custom design 64-bit design. K12 is the name of the second highest peak situated in the Karakoram range so Summit Ridge as a whole may be a reference to peak in performance and efficiency since this is a completely new architecture.

The upcoming bits get even more interesting with the report alleging that AMD’s next cores are shifting from 32nm straight down to 14nm. The Summit Ridge series will contain up to 8 x86 cores based on the AMD Zen architecture and will be manufactured by either Samsung or Global Foundries. On power side, while AMD’s FX series currently pushes the TDP to 95W on APUs, 125W on FX series and 220W on the 5 GHz series, the Zen based processors will feature a maximum TDP of 95W which is inline with Intel’s 22nm Haswell offerings and also what Broadwell is supposedly going to get when it launches on desktop sometime in mid-2015. There will also be more power efficient variants toning the TDP down to more conservative levels as Zen will be featured across the board and is likely to be as scalable as Broadwell architecture which has seen 4.5W TDP variants in the form of Broadwell-Y.


On the main architectural side of things, AMD Zen cores will take the best from Bulldozer and Jaguar, delivering a SMT (Simultaneous Multithreaded) design that takes advantage of the various resources in the core and dedicate it to an additional execution thread for added throughput. This adds to the area efficiency of the core design and reduces the effect of stalls and pipeline back pressure leading to improved resource utilization inside the core which in turn improves overall performance.

Everyone knows that Bulldozer was not the game changing part when it was introduced three years ago. We have to live with that for four years but Zen, K12 we went out and got Jim Keller we went out and got Raja Koduri from Apple, Mark Papermaster, Lisa sue. We are building now our next generation graphics and compute technology that customers are very interested in and they’ll ( referring to the next generation graphics and compute architecture) move to the next generation node and they’ll be ready to go.

There are also talks regarding the platforms where it’s mentioned that AMD is planning to make a new socket called AMD FM3. There’s no mention what platform is the FM3 socket intended for, some might say that it is the successor to the FM2+ but it might be AMD planning to unify all of their processors on a same socket since that’s what they are going to do Project Sjybridge offering pin-to-pin compatibility for x86 and ARM chips. AMD also adopted a similar design for Carrizo and Carrizo-L which are pin-to-pin compatible. This socket unification project may extend to Zen offering compatibility of high-performance consumer processors and server chips on the same socket. It is said that all Zen based chips will include a northbridge on the same silicon as the CPU and the new southbridge for motherboards will be known as Promontory which is also a reference to land mass like the K12 peak, summit and ridge references in their new naming schemes.

The report alleges that Summit Ridge featuring AMD Zen architecture will make its way only in 2016 since the series was pushed to Q3 of 2016 from an earlier time frame it was previously expected to launch. Regardless of the date, the new AMD Zen based Summit ridge family will enter the market five years after the launch of first generation Bulldozer.
