Review: Speed updates, one Phenom is an Athlon

After the X-Mas rush AMD was keen to introduce a few new CPUs. The flagship Phenom II X6 is now clocked at 3.3GHz, Turbo goes up to 3.7GHz, and it still has 64kB of L1 cache per dice for data and instructions, 512kB L2 cache per dice and 6MB shared 3rd Level Cache. The TDP stays at 125W and VCore runs at 1.3500V.

The second introduction was the Phenom II X4 840, which striked us oddly. While in the name suggests 3rd level cache, this one has none. It is in fact the successor to the Athlon II X4 645, with a 100MHz higher clock which now stands at 3.2GHz. Why it's called Phenom instead of Athlon II X4 650 is anyone's guess. The Vcore went up from 1.3500V to 1.4000V, still 64kB L1 cache per dice for data and instructions, 512kB L2 cache per dice and an TDP of 95W.

All tests are performed with XP SP3. As 64-bit software is still not very common, we used the 32-bit version.
