<div>thank you for your information. I'll check the benchmark on your website.</div>
<div> </div>
<div>I'm very glad to hear I7 greatly promote the performance of QE. We will consider it. could you please </div>

<br>This is a very informal page (so skip most of the stuff, and just<br>look at Machine 4, and the AgI CP tests. These are standard<br>tests we perform, and that are detailed more broadly in<br><a href="http://quasiamore.mit.edu/pmwiki/index.php?n=Main.CP90Timings" target="_blank">http://quasiamore.mit.edu/pmwiki/index.php?n=Main.CP90Timings</a> ).<br>
<br>Note that the tests above were done on a remote machine that<br>was poorly ventilated.<br><br>I think Davide Ceresoli might have some more recent results on<br>a 4-core extreme edition at 3.xx GHz . Davide, could you<br>
add those to the wiki ?<br><br>The Xeons are coming out next week, indeed (2 cpus on the<br>same motherboard).<br><br>But our impression was that the improved bandwidth made it very<br>much worth going for the i7.<br><br>
