We'd already seen a few early tests of AMD's new top-end Phenom X4 9850 processor, but the folks at Extreme Tech have now taken it upon themselves to see just how well the processor stacks up against Intel's similarly high-end offering, the Core 2 Quad Q9300. As was suggested by those other reviews, however, the AMD falls behind the (admittedly pricier) Intel processor in just about every respect, including its ability to be overclocked. On the upside, however, that lower cost will likely offset the performance issues for many users, and it does still boast "moderate overclockability" and run cooler than the Intel chip. ExtremeTech apparently isn't convinced that AMD's pricing is "sustainable over the long haul" though. For its part, the Q9300 makes the most of its four cores and 45nm manufacturing process, with the only significant downside being that it packs only have the cache of the rest of Intel's quad core line. That wasn't enough to stop it from snagging an impressive 9 out of 10 rating, however, with ExtremeTech declaring it "one of the best price/performance CPUs you can find."
