Everest Ultimate Edition 4.60 Memory Performance
To help determine if these outlandish memory bandwidth scores are legit, we've added the Everest Ultimate Edition to the benchmark suite. Everest is similar to SiSoft SANDRA, as it provides both system diagnostic and informational programs, while also incorporating various memory and CPU benchmarks. As these utilize a different process than SANDRA, this could give us another peek at the true memory performance of the new Core i7 processors. We have tested each of the CPUs and platforms under the Everest Memory Read, Write, Copy and Latency benchmarks.
We're starting off with the Memory Read benchmark, which again, shows the Core i7 processors posting some incredible memory bandwidth scores. These CPUs are light years ahead of the top last-generation models from Intel and AMD, and in some cases, post results double that of the competition. We'll have to see if this holds up through all Everest testing, but for now, it looks very promising.
The Everest Memory Write scores are even more impressive, as the Core i7 processors maintain a similar performance level to the Memory Write testing, while the other AMD and Intel processors fall back.
We don't see a changing of the guard in the Memory Copy benchmarking, and again, it's the three Core i7 processors giving the others a lesson in true memory performance.
We round out the Everest benchmark suite with a Memory Latency test, and it's hardly a surprise to see the Core i7 lineup with a distinct advantage over the competition. These are very low latencies, and show the benefits of combining an integrated memory controller with a triple-channel DDR3 architecture.
