16-core ''Warsaw'' CPUs added to Opteron lineup

— 7:00 AM on January 22, 2014

AMD has added a couple of server processors to the Opteron 6300 series. These new offerings are based on Warsaw, which appears to be a power-optimized version of the silicon anchoring existing members of the 6300 family. Like the current models, the latest additions are built on 32-nm fabrication technology and based on Piledriver CPU cores. They have the same cache configurations, and they're reliant on the same dual-die approach to provide six- and eight-module configurations with 12 and 16 cores, respectively.

The new models include the Opteron 6370P, a 16-core chip with a 2GHz base clock speed and a 2.5GHz Turbo peak, and the Opteron 6338P, which has 12 cores clocked at 2.3/2.8GHz. Here's how those stack up against the other 12- and 16-core chips in the Opteron 6300 series.

Model Cores Base clock Max Turbo clock Power band
6386 SE 16 2.8GHz 3.5GHz 140W $1392
6380 16 2.5GHz 3.4GHz 115W $1088
6378 16 2.4GHz 3.3GHz 115W $867
6376 16 2.3GHz 3.2GHz 115W $703
6370P 16 2.0GHz 2.5GHz 99W $598
6348 12 2.8GHz 3.4GHz 115W $575
6344 12 2.6GHz 3.2GHz 115W $415
6338P 12 2.3GHz 2.8GHz 99W $377

The Warsaw-based models have lower base and Turbo frequencies, but they're also cheaper than the higher-clocked options. That makes sense, since the chips are "optimized to deliver improved performance per-watt for virtualized private cloud deployments with less power and at lower cost points," according to AMD.

AMD's press release provides "power band" figures instead of traditional TDP ratings. However, the accompanying quick reference guide suggests that's just new terminology for the same metric. The power band ratings for the older members of the Opteron 6300 series match the TDP ratings for those chips. The thermal envelope for these latest Opterons is only 99W, 16W lower than for the bulk of the 12- and 16-core lineup.

The Opteron 6370P and 6338P are available starting today from multiple system integrators. They've also been qualified for servers from Sugon and Supermicro.
