AMD Zen server chip shows up in SiSoft Sandra database

Some benchmarks of the AMD Diesel server platform have found their way to the SiSoft Sandra database. The entries reveal some preliminary performance of the Naples variant of the Zen processor, it's a 2S dual-socket configuration with a total of 64 cores and 128 threads. The engineering sample used here has a 1.44GHz base clock and a 2.9GHz Turbo.

The benchmarks given above confirm some interesting specifications of Zen architecture. First of all, as we have been saying for the past year, the full Naples configuration will have 16 clusters of 512 KB L2 and 4 clusters of 8 MB shared L3. The PCI bandwidth is shown as 310 MB/s and the cryptography benchmarks are clocking out at 170 MB/s. These values are not up to par of what should theoretically be the performance of a 64 core setup so it is a fairly safe bet that the benchmark is not utilizing the processor properly here. As we have told you before, Zen will introduce some brand new cryptography tricks so it is probable that the benchmark is not able to utilize these new abilities.

More photos of the benchmark results can be viewed at WCCF Tech. So overall this confirms Zen is making the rounds at the moment but it doesn't really provide any clues for the desktop performance of the chip.
