Nehalem is not overly well optimized to do much of anything with single threaded apps, which represent most of the bulk of the software sold out there in cyberland. At most you will see about a 10% performance increase clock per clock, quad core per quad core. So a Bloomfield running at 2.66 GHz will outrun a Q9450 by roughly 10% on benchmarks that involve single threads. However, feed the Bloomy a blooming multithreaded app, and watch it leave the Penryn in its trail with up to double the performance.
is all this information correct?
