AMD Turion II N550 vs AMD Turion II P540
AMD Turion II N550► remove
The AMD Turion II Dual-Core N550 ist a mobile laptop processor with two cores. It is based on the desktop Athlon II processors (due to the missing level 3 cache) and offers an integrated DDR3-1066 memory controller. The connection to the chipset is done with a single 16-Bit HyperTransport 3.0 link clocked at 1800MHz (3600MHz effective).
Compared to Intel Core 2 Duo processors at that clock range, the Turion II offers less cache and is therefore slower. Furthermore, comparing two CPUs with the same amount of cache, the Intel CPUs are still a bit faster (by 100 MHz on the average).
With 35 Watt TDP, the CPU is intended for mid sized laptops with a display size of 14-inches and larger.
AMD Turion II P540► remove
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.
