AMD Details Bulldozer at ISSCC

At the core of Bulldozer processors are "modules", which integrates two "tightly linked" and slim processor cores. According to AMD, the cores integrate their own L1 caches, but share high-bandwidth resources such as a floating point unit, L2 cache as well as fetch, decode and prediction units  to enable "chip multi-threading (CMT). Intel, in contrast uses an approach called chip multi-processing, which uses complete individual cores and multi-threading.

AMD said that Bulldozer will run at clock speeds of up to 3.5 GHz. The processors will be manufactured by GlobalFoundries in a 32 nm process. One Bulldozer module with two cores will house about 213 million transistors and have a surface area of just 31 mm, including L2 cache.

The upcoming 8-core Bulldozer processors are likely to have more than 1 billion transistors as the entire chip will also integrate L3 cache as well as a Hypertransport 3.1 controller. The future Valencia Opteron, which will likely be called the Opteron 4200 series, will be available with six and eight cores.  The Opteron 6200, code-named Interlagos, will debut with 8, 12 and 16 cores.

    So AMD is really hitting it hard with core expansion. I thought the "core race" was supposed to be dead? Personally it sounds to me like the way things will end up, so maybe AMD is taking a step in the right direction?

    ARGH!!!!!! Give a release date and some benchmarks AMD!!! If you don't release info soon I am upgrading to the sandy bridge platform.

    I think the limit to core expansion will be when the manufacturers can't deliver a reliable core count at a given manufacturing size (nm). Even then it will only be temporary.

    The real limit will be when/if we actually need 12 or 16 or more cores for everyday use.

    16 cores with 2 near separate cores, but only one fp unit between them. I'd say these likely won't be good for gaming but will be very good for server work. We'll have to wait and see...

  • As much as I want to back the underdog here, it is hard to do it if they don't even bring a horse to the race. Even if this thing has 50 cores and 90billion transistors on a 2nm die on paper, it means nothing when there isn't a product.

    AMD might as well start research on Star Trek transporter technology.

    Like others said, this is just the same info rehashed again. Nothing to see here, move along.
