Memory Latency

First up is the memory latency benchmark, a component of Everest from Lavalys. This should give us an idea of how timings affect performance, eliminating all other factors. However, don't expect all results to look like this.

I'll also take this time to explain how these charts are laid out.

Obviously, the AMD results use AMD's colours, while Intel's results use Intel's colours. For AMD, the light green bars refer to non-overlocked timings. There is a low-latency result, and a high latency result. Intel's non-overclocked timings are in blue.

The dark green bars refer to AMD's overclocked results, and the orange bars are Intel's overclocked results. Note that we attempted to keep CPU and bus clock speed from being a factor, so those timings were altered to try to remain as close to standard clock speeds as possible. Just keep in mind that this is NOT an "Intel vs AMD" review (for that, click here). Timings were skewed to the point where these benchmarks mean little in terms of CPU performance.

I hope this all makes sense! It did to me when I designed these tests at least ;)

The first result shows what we expected - lower memory latency specs equals better memory latency performance. Of course, increasing the bus speed by a significant amount will have the same effect, so the overclocked results shown above are essentially meaningless.

Memory Bandwidth

For a look at how latency has an overall effect on a system's memory bandwidth, we turn to SiSoft Sandra 2009's benchmark module.

There's a lot of information to digest here. First of all, looking at the non-overclocked timings, you can see that there is a sligh increase in overall bandwidth when just the memory timings are lowered. On the Intel side, bandwidth increased by nearly 1 GB per second just by increasing the DDR speed (FSB and CPU clock speeds were not touched). Increasing the memory speed, and FSB speed further would increase performance, but this is largely negated with lower timings.

On the AMD side, well... 1065 DDR2 is just crazy, what can I say? ;)
