Aside from a lower Maximum Thermal Power rating of 45w, the AMD Athlon X2 BE-23xx series isn't all that different from other "Brisbane" based CPUs. The major difference is the newer processors sport a lower operating voltage range of 1.15-1.20v where the 65w "Brisbane" ranges from 1.25-1.35v and the "Windsor" cores are rated at 1.3-1.35v. Other than that, there’s no new features to report as CPU-Z shows below. (Note: The latest release BIOS reports our review sample as a BE-235, which is an error in the BIOS code. The newer Beta BIOS has this corrected, however, we didn't feel it appropriate to do our testing with a Beta BIOS).
BE-23xx series processors are manufactured at 65nm and use the 940 Pin AM2 specifications. The "Brisbane" still follows the standard model of a 512KB L2 cache which is implemented across all "Brisbane" processors. The core sports the same 64 L1 instruction and 64K L1 data cache while the integrated 128-Bit dual channel memory controller supports up to 800MHz DDR2. When looking at the picture of the CPU, don't be confused by the "64" stamped on it, retail models will not carry the "64" designation any longer. While the Athlon X2 BE-2350 is clocked at 2.1GHz, the Athlon X2 BE-2300 comes clocked 200MHz slower at 1.9GHz and costs a few dollars less.
