32nm Westmere prototypes leaked and benchmarked
Posted: Mon Apr 27, 2009 11:38 pm
We recently heard that Intel had sent out samples of its 32nm Westmere processors to no fewer than 30 PC manufacturers. Well, those CPUs didn't take long to fall into the public eye. XtremeSystems forum member JCornell got hold of two of them, and he's posted photos and the result of an early benchmark for all to see.
The XtremeSystems forum thread seems to have mysteriously disappeared (the link now points to an innocuous Core i7 water-cooling thread), but Google still hosts an intact cached version. According to the cache, JCornell showed pictures of both Clarkdale and Havendale—the desktop and mobile variants of Westmere. Both have similar-looking packages with LGA-style contacts at the bottom.
In Google's cache of +Intel+Clarkdale+page+2&cd=3&hl=en&ct=clnk]the thread's second page, you can still see a screenshot of a SuperPI benchmark run on the Havendale sample. At 2.4GHz with 256KB of L2 cache per core, 4MB of L3 cache per chip, two cores, and four threads, the processor apparently managed to complete a 1M SuperPI run in 18.125 seconds.
That's a 10% performance gain over current Core processors running at the same speed.
