Testing and Comparison -SiSoft Sandra Tests:

SiSoft Sandra Cache and Memory test

Benchmark the processors’ caches and memory access (transfer speed).

Combined Index: is a composite figure representing the overall performance rating of the entire Cache-Memory performance in terms of MB/s. The value is the logarithmic average of all the results for the entire address space. (Higher is better, i.e. better performance)

Speed Factor: is a figure representing the speed differential between the CPU’s cache and memory. The value is the ratio of the fastest cache (i.e. L1) bandwidth to the main memory bandwidth. (Lower is better, i.e. the memory is not very much slower than CPU’s cache)

Not bad performance by the Super Talent easily beating out the Ballistix that runs much faster at 1066Mhz and the GSkill with the same speed, but not either set of OCZ ram.

CPU Arithmetic Benchmark

Benchmarks the ALU and FPU processor units. Shows how your processors handle arithmetic and floating point instructions.

Results Interpretation : Higher index values are better.

Memory Bandwidth Benchmark

Benchmarks the memory bandwidth of your computer.

Results Interpretation : Higher index values are better.

Very close scores all around here, either set would be a good choice really.

Memory Bandwidth Benchmark

Benchmarks the memory bandwidth of your computer.

Results Interpretation : Higher index values are better.

Here, surprisingly the GSkill bests the Super Talent, still though all scores are close.

Memory Latency Benchmark.

Benchmark the latency (response time) of processors’ caches and memory

The latency of caches is measured in processor clocks (i.e. how many clocks it takes for the data to be ready) as it is dependent on the processor clock speed.

The latency of memory is measured in nanoseconds as it is typically independent on processor clock speed.

Results Interpretation : Lower index values are better.

Not much to say here, the sets of OCZ clearly beat the others in the Latency Tests.

Multi-Core Efficiency

Benchmark the multi-core efficiency of the processors. Shows how efficient the processor cores and their inter-connects are in comparison to other types to other typical processors.

The ability of the cores to process data blocks and pass them to another core for processing (producer-consumer paradigm) of different sizes and different chain sizes is measured. The efficiency of the inter-connect between cores is thus benchmarked; however, the number of cores (and processors) also counts as more data buffers can be processed simultaneously (aka “in flight”).

True multi-core processors that have shared L2/L3 caches will thus perform much better than cores that have separate caches and are connected by the traditional FSB.

Inter-Core Bandwidth :Results Interpretation : Higher index values are better.

Inter-Core Latency :Results Interpretation : Lower index values are better.

We can see here that higher speeds and lower latencies are the clear winners

Processor Multi-Media

Benchmark the (W)MMX, SSE/2/3/4 processor units. Shows how your processors handle multi-media instructions and data in comparison to other typical processors.

Such operations are used by more specialized software, e.g. image manipulation, video decoders/encoders, games.

Results Interpretation : Higher index values are better

Here again we’ve got some very close scores.

It all depends on what you want in a set of ram, if you are trying to eek out every last bit from your ram then well you can choose a winner from these tests, but in real world performance I don’t think you’d ever notice the difference between any of these sets of ram if they were in your system.

As for any overclocking I did play with this set a bit and I found it can run at Cas4 with the stock voltage easily, and I found that it could run at speeds of DDR2-900. Looking around though I found others have pushed this set of memory a bit farther, but as with any memory it all depends on the luck of the draw as to what your set of memory can do…
