AMD Athlon II 255 and 260

SiSoft Sandra:

We love to use SiSoft as it provides a wide barrage of benchmarks for a particular system

	Cache and Memory – 255	Cache and Memory – 260

The cache and memory test helps benchmark the on board cache of the processor. We can see that the 255 has a cache and memory bandwidth of 26.24 GB/s while the 260 weighs in at 28.36 GB/s.

	Memory Bandwidth – 255	Memory Bandwidth – 260

For the memory bandwidth benchmark, the 255 scores an aggregate memory performance of 9.45 GB/s while the 260 scores 10.22 GB/s

	Memory Latency – 255	Memory Latency – 260

The 255 has a memory latency of 90 ns and the 260 is 82 ns. A faster chip means less latency and better performance.

	Multi-Core Efficiency – 255	Multi-Core Efficiency – 260

There isn’t too much difference in efficiency as they are almost the same chip. The 255 scores 3.1 GB/s while the 260 scores 3.24 GB/s.

	Power Management Efficiency – 255	Power Management Efficiency – 260

The power management efficiency is measured in MIPS or millions of instructions per second. The 255 performs at 7642 MIPS and the 260 at 8386 MIPS.

	Processor Arithmetic – 255	Processor Arithmetic – 260

The processor arithmetic benchmark is used to determine how well a processor can handle arithmetic instruction. The 255 scores an aggregate performance of 19.65 GOPS while the 260 scores 20.29 GOPS.

	Processor Multi-Media – 255	Processor Multi-Media – 260

This benchmarks is supposed to gauge the expected performance in multimedia applications. The 255 has an aggregate performance of 57.5 MPixels/s and the 260 has 59.4 MPixels/s, owing the win the its faster clock speed.
