AMD Phenom II X4 X920 BE

The AMD Phenom II X4 X920 BE (Black Edition) Quad Core was the fastest version of the Phenom II X4 for laptops in Q2 2010 and features an unlocked multiplier for easy overclocking. It was later replaced by the 100 MHz higher clocked X940 BE. With 45W TDP the AMD CPU needs as much power as the Core i7 quad cores but due to the missing level 3 cache, the performance should be worse. Compared to the desktop CPUs, the mobile Phenom II X4 is similar to a Athlon II X4 and produced in 45nm SOI.

The performance of the X920 differs from benchmark to benchmark. If only one core is used, the AMD quad core processor is only on par with a slow 2 GHz Core 2 Duo (e.g. Cinebench R10 Single). The old single threaded SuperPi benchmark is traditionally for AMD even worst on a level of a 1.4 GHz Core 2 Duo. However, if all four cores are used, the performance scores are in regions of the fast dual cores Core i5-540M to i7-640M (Cinebench R10 Multi, wPrieme 2, CB 11.5). The slowest Core i7 quad core (720QM) is still in every benchmark faster than the AMD CPU.

The Phenom II includes an integrated memory controller for DDR3 (max. 1333) main memory. It supports MMX, 3DNow!, SSE, SSE2, SSE3, SSE4A.
