| AMD Naples is now called Epyc and brings from June 32 Zen cores for servers |

| AMD is adopting the Opteron brand, bringing CPUs with the brand name Epyc to the server segment in June 2017. As a base, Naples uses four Zeppelin-Dies, that is, up to 32 Zen cores. AMD also showed how the MCM package looks under the large heat spreader. The large server CPUs with 16 to 32 cores has so far dealt AMD under the code name Naples. Within the scope of yesterday's Financial Analyst Days 2017, the chip maker unveiled the new brand name for the first time. The Zen-based server CPUs are under Epyc, which should offer an "epic" performance compared to Intel's Xeons Server CPUs. Ambitiously, AMD's promise is definitely out. Even in the case of Ryzen, AMD has cut the old braids with FX and Athlon. Now follows the server segment which AMD's CPUs were called Opteron. New brand names are selling AMD's intention to leave behind the bad reputation of the Bulldozer architecture. The Zen CPUs with code names Naples serve for the copied LGA socket SP3 with 4,094 pin contacts. This offers up to 32 cores (64 threads) and is based on four smaller Zeppelin-Dies, as AMD also for Ryzen 7 and Ryzen 5. Thanks to the Infinity Fabric Interconnect, the performance is expected to increase almost linearly despite the MCM design (multi-chip modle). The physically separate CPUs act on the organic package like a mapped CCX within a chip, which makes AMD expect a strong scaling. The construction has three decisive advantages: many small ones are significantly cheaper to produce than a few large ones because of the better yield. In addition, AMD saves development and validation costs for additional benefits. Market introduction can take place much faster. AMD promises that the Epyc CPUs will differ only in the core number and the clock. All I / O ports, memory channels and other features should always be activated. 16 kernels must therefore already be implemented with four This, in which four cores are deactivated. In addition, AMD does not provide separate models for 2-socket systems. At Intel there are strict separations in all areas. Naples supports 1- and 2-socket systems, with AMD particularly wanting to interfere with Intel's 2-socket pre-registration with 1-socket systems. The Xeon E5 (currently 22 Broadwell cores) with two CPUs per motherboard (a total of 44 cores) are the most widespread, the power of AMD would reach or even exceed with a single 32-core Epyc. The Octo-Channel memory interface, which can be used to connect 16 RAM banks (which means a lot of RAM), as well as the lavish I / O configuration including 128 PCI Express lanes, helps. 2-socket systems provides AMD for high-performance systems. Rome will replace Naples with Zen2 nuclei in 7 nm - rumored to be a starchip with 48 nuclei - later Milan follows Zen3 nuclei and in "7+" nm. |
