Information leaked onto the web regarding AMD's upcoming 12-core Opteron processors at the website of an online shop.

The Opteron X12 6164 runs at 1.7GHz and has 16MB of cache and it costs $797, while the 6136 is clocked at 2.4GHz, packs 18MB of cache and costs $808. The slower version runs on just 65W of power, while the 2.4GHz model consumes 105W, which sounds quite impressive.

The X12 6176 is clocked at 2.3GHz and it has 18MB of cache, but at $1,491 it's the priciest of the lot. The 2.2GHz 6174 costs $1,250, while the 2.1GHz 6172 is priced at $1,060.

The twelve cores will have reduced clock speeds but will not draw more power than 6-core versions. Even though the clock frequencies will fall, Magny-Cours chips will pack more performance compared to existing Opteron chips, Conway said. The larger cache and increased cores will make servers faster. The company's upcoming 12-core server chips, code-named Magny-Cours, put two six-core chips in one package. The same silicon is used in its six-core chips, code-named Istanbul, which are part of the Opteron line of server processors.

Finer details in the Magny-Cours chip. Two six-core chips are connected by four hyperthreaded interconnects and are targeted at two- and four-socket servers, Conway said. It includes a total of 12MB of L3 cache, with each core supporting 512KB of L2 cache. The chips will be manufactured by AMD's spinoff, GlobalFoundries, using existing 45-nanometer technology.

AMD is also working on a new x86 chip architecture code-named Bulldozer. The architecture will be used in chips manufactured using the 32-nm process in 2011. The company has scheduled a 16-core chip code-named Interlagos for release in 2011 [via computerworld].

Magny Cours = Many Cores :)
