New Opterons ahoy! AMD has added 12 new models to its server and workstation processor lineup, simultaneously bringing its lowest-power and highest-clocked quad-core Opterons yet. The most energy-efficient offerings have ACP ratings of just 40W, while the fastest new Opterons run at up to 3.1GHz—although that speed comes at the cost of a more imposing 105W rating.
Here's a full list of the Opterons AMD is launching today. All of the following have four cores and are based on AMD's 45nm Shanghai design:
|Model||Clock speed||ACP rating|
|Opteron 2373 EE||2.1GHz||40W|
|Opteron 2377 EE||2.3GHz||40W|
|Opteron 2379 HE||2.4GHz||55W|
|Opteron 8379 HE||2.4GHz||55W|
|Opteron 2381 HE||2.5GHz||55W|
|Opteron 8381 HE||2.5GHz||55W|
|Opteron 2393 SE||3.1GHz||105W|
|Opteron 8393 SE||3.1GHz||105W|
Most of the newcomers are effectively higher-clocked versions of previous Shanghai CPUs, but the Opteron EEs make up an entirely new product category. AMD says these low-power processors should be an ideal fit for "dense environments" like cloud-computing applications—a purportedly burgeoning market. (The launch presentation quoted IDC and AMD research that says cloud-computing spending is growing at six times the overall IT spending rate.)
The Opteron 2373 EE and 2377 EE may not have the highest clock speeds, but AMD is quick to stress that they have the same functionality as their faster brethren, including 6MB of L3 cache per chip and hardware virtualization support. In fact, AMD tells us it didn't have to make any circuit design changes in order to reach lower power envelopes. These 40W CPUs are simply the product of binning and yield improvements.
AMD claims the Opteron 2377 EE delivers a 63% performance-per-watt increase over the 65nm, 75W Opteron 2356 in SPECpower_ssj2008. Since the new EE parts should be drop-in compatible with all Socket F platforms, they could also serve as interesting upgrade options for current servers.
