Bulldozer goes pro with Opteron 4200, 6200 processors

AMD didn't wait too long to unleash the workstation- and server-bound versions of its new Bulldozer microarchitecture. The company has just announced the "immediate launch and availability" of its 32-nm Opteron 4200 and 6200 chips, which are succeeding the 4100 and 6100 series in the company's existing Socket C32 and G34 platforms, respectively. Where desktop implementations of Bulldozer max out at eight cores and dual memory channels, some of these new server offerings deliver twice as many of each—all in the same power envelopes as previous-gen models.

Here's the new Socket G34 lineup. As a reminder, the Socket G34 platform enables two or four CPU sockets, quad DDR3 memory channels per socket, and up to 12 DIMMs per socket:

Model Cores Clock speed Peak Turbo speed L3 cache TDP Price
6282 SE 16 2.6GHz 3.3GHz 16MB 140W $1019
6276 16 2.3GHz 3.2GHz 16MB 115W $788
6274 16 2.2GHz 3.1GHz 16MB 115W $639
6272 16 2.1GHz 3.0GHz 16MB 115W $523
6238 12 2.6GHz 3.2GHz 16MB 115W $455
6234 12 2.4GHz 3.0GHz 16MB 115W $377
6220 8 3.0GHz 3.6GHz 16MB 115W $523
6212 8 2.6GHz 3.2GHz 16MB 115W $266
6204 4 3.3GHz N/A 16MB 115W $455
6262 HE 16 1.6GHz 2.9GHz 16MB 85W $523

...and here's the C32 family. AMD's Socket C32 platform enables one- or two-socket configs, with two memory channels and as many as four DIMMs per socket:

Model Cores Clock speed Peak Turbo speed L3 cache TDP Price
4284 8 3.0GHz 3.7GHz 8MB 95W $316
4280 8 2.8GHz 3.5GHz 8MB 95W $255
4238 6 3.3GHz 3.7GHz 8MB 95W $255
4234 6 3.1GHz 3.5GHz 8MB 95W $174
4226 6 2.7GHz 3.1GHz 8MB 95W $125
4274 HE 8 2.5GHz 3.5GHz 8MB 65W $377
4228 HE 6 2.8GHz 3.6GHz 8MB 65W $255
4256 EE 8 1.6GHz 2.8GHz 8MB 35W $377

All of the chips above support DDR3-1600 memory speeds, for what it's worth. Be sure to check out our Bulldozer review for the skinny on AMD's new microarchitecture.

In addition to the new chips, AMD says it has "announced the expansion of its 2012 roadmap." That expansion involves the Opteron 3000 series, a new Bulldozer-based lineup aimed at the same AM3+ socket type used by desktop FX-series processors (though, of course, server-friendly features like ECC memory support will be on the menu). The Opteron 3000 family will debut in the first half of next year, and it will be aimed at "the ultra-dense, ultra-low power 1P Web Hosting/Web Serving and Microserver markets."
