The successor to the architecture AMD Bulldozer called Zen and the introduction of processor family Summit Ridge, which take the step to 14 nanometers.
The three-year-old architecture Bulldozer is still the basis of AMD's highest-performing processors, a severely criticized structure that has recently been recognized as a failure. Despite the fact that it takes almost two years before the successor sees the light has the processor manufacturer has already begun Hausa coming Zen - one from scratch new architecture developed by the renowned engineer Jim Keller at the tip.
Now, vBulletin Solutions reveal that the first with the architecture AMD Zen gets the family Summit Ridge with processors containing up to eight cores. Meanwhile taken a giant leap from 32 nanometers (for today's FX series) down to 14 nanometers , suggesting that Samsung or Globalfoundries will be the manufacturer.
Progress should not at least reduce power consumption. Today's most energy-efficient models in the FX series lands at 95 W TDP, something that extends up to 125 and breathtaking 220 W super-hot models. For Summit Ridge same is "up to 95 W," which suggests that there will be more power-efficient variants.
Intel introduced the new memory standard DDR4 with the architecture Haswell-E and later this year will Skylake also take the type of memory at a lower price ranges. AMD plans to take the same steps to Summit Ridge. However, it is unclear if it is two or four channels DDR4, although the former is more likely.
New features include the hitherto unknown socket AMD FM3, which is likely to be a direct sequel to today FM2 +. It may be noted that nothing so far is mentioned about the integrated graphics parts of the processor. In contrast, choosing AMD to integrate northbridge on the same silicon, which assists with a still unknown number of channels PCI Express 3.0. In addition, a new southbridge code-named "Promontory".
It is also short on details about the architecture Zen, where the only AMD gossiping about is to retain the "best" from Bulldozer and Jaguar in processors intended for both servers and consumer markets. Anecdotal evidence alleges that AMD departing from the Cluster-Based Multithreading , the modular design where the two cores share resources, for the benefit of Simultaneous Multithreading , where each core can execute two simultaneous threads. The corresponding feature found in Intel's processors under the name Hyperthreading.
Anyone who looks forward to the launch of the AMD processor family Zen and the Summit Ridge may be prepared to wait a long time. Reportedly vBulletin delayed the launch until the third quarter of 2016, ie almost five years after the introduction of the first generation Bulldozer.
