AMD Turion II P520 vs AMD Turion II P540

AMD Turion II P520

The AMD Turion II Dual-Core Mobile P520 is a dual-core processor for laptops based on the same architecture like the desktop Athlon II CPUs (K10.5 with missing level 3 cache). The CPU integrates a 533 MHz dual-channel DDR3 memory controller and communicates with a single 1800 MHz 16-Bit HyperTransport 3.0 link. The Turion II P520 is manufactured in 45nm SOI.

The performance is somewhere between a 2.1 GHz Core 2 Duo (e.g. T4300 in Cinebench 10 Multi) and a 2.3 GHz Core 2 Duo (e.g. wPrime). Therefore, the CPU is positioned in the entry level for multimedia laptops.

AMD Turion II P540

The AMD Turion II Dual-Core Mobile P540 is a dual-core processor for laptops based on the same architecture like the desktop Athlon II CPUs (K10.5 with missing level 3 cache). The CPU integrates a 533 MHz dual-channel DDR3 memory controller and communicates with a single 1800 MHz 16-Bit HyperTransport 3.0 link. The Turion II P540 is manufactured in 45nm SOI.

The performance is hard to compare to a current Intel CPU. On average it should be on par with a Core 2 Duo / Pentium Dual-Core at the same clock speed and cache size. As most Core 2 Duo at this speed have a much larger Level 2 cache, the performance lies beyond the typical Core 2 Duo at 2.4 GHz.

Compared to the slightly faster clocked Turion II N530, the P540 is rated at a lower TDP of 25 Watt.
