Feeding the Beast: 2x Cache Bandwidth in Haswell

With an outright doubling of peak FP throughput in Haswell, Intel had to ensure that the execution units had ample bandwidth to the caches to sustain performance. As a result L1 bandwidth is doubled, as is the interface between the L1 and L2 caches.

L1/L2 cache latencies and sizes remain unchanged. The same isn't true for the L3 cache however.

    Couldn't agree more, this article really brightened up what was otherwise a pretty miserable afternoon here in London.

    When am I going to be able to walk into a shop and buy something with Haswell inside it? Next March maybe?

    As stated in the article, Haswell is coming in the summer of 2013. Reply

    How do I downvote stupid crap like this "Tag team Intel fanboy puke." comment so that collectively we can see high quality comments without having to wade through the interturds as well? It really takes away from the best article I have read in a long time. Not because it is about Intel, but because it is about the state of the art. Reply

    Well, I'd also ask how do I downvote stupid butt kissing like OP, while we are at rating.... Reply

    Many people enjoy well written and informative articles. Are you telling me that if you wrote, you would not enjoy positive feedback from your readers? Reply

    Not sure about him, but I've looked into this article to figure power targets for haswell (especially interesting to compare to ARM crowd), NOT to read orgasmic comments about eternal wizdom of Intel's engineering... Reply
