AMD Details Bulldozer at ISSCC

By - Source: AMD | B 99 comments

AMD chose the annual ISSCC conference to take the wraps off its Bulldozer core, which is targeting server and high-end desktop processors.

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.

    This wait is getting tiresome. Maybe I'll do Intel for my next build.

    You know it's going to be crap because they're talking about architecture instead of performance.

    Yeah AMD is M.I.A! Atleast we know how fast sandy bridge is already. The i5 2500k is more then i need and for a decent price.

    Um do you guys realise Intel was a little quick to release Sandy Bridge and all you have is a Billion dollars worth of paper weights. There is absolutley nothing that requires home users to have thses AMD chips at the moment. AMD take your time and get it right ...

    be patient...i am sure that you can wait a little longer...intel is and will allways be better than AMD

    Is it coming soon? 2012...? The world ends, it'll be to late by then.

    My 2+ year old core2 Quad is looking for an AMD replacement.

    Eliminate AMD and Intel will cease to innovate at more than a snales pace. Who cares about buying Intels latest and greatest when both AMD and Intel will pass your benchmark in the near future anyway. Be smart support what's important as the ignorant masses continue to Mcdonaldize everything.

    killerclick you obviously have no common sense to say what you said. How the hell do you know that bulldozer 8 cores are going to be crap. I suppose you can foresee the future. AND using just logic and common sense it is pretty obvious they are not going to be crap because why would AMD spend years developing "crap". That would be stupid for a company to develop "crap" because they would waste all that money. Use some common sense Killerclick, stop being dumb.

    I agree though AMD needs to tell the public an actual target date when these will be available to purchase. I want to buy one but I may end up getting a sandybridge even though the southbridge chipset is having some problems. The 2600K is pretty solid. And Killerclick AMD has stated estimated performance figures before if you just do some simple searching you can find the figures. And coming from a company standpoint, the performance figures AMD stated for their 8 core bulldozer CPUS are probably a little bit lower than they actually will be. AMD is not a favorite among the majority of pc users, so I doubt AMD would overstate the performance of their CPU's because that would piss a lot of people off if the CPU's fell short of AMD's performance figures. I would think that when the 8 core Zambezi is released that it will be faster than what AMD has said in the past. For anyone wondering, AMD said that the 8 core Zambezi is supposed to be 50% faster than a core i7-950 in gaming to give you an idea of performance. I expect that it will even be a little faster.

    When they mentioned benchmarks for Barcelona, everyone said "it's only 30% not 40% faster." Just be careful cause I still don't know how to judge i3,i5,i7 with the 3xx, 4xx, 5xx, 7xx, 8xx, 9xx. At least AMD doesn't castrate chips to charge less.
