..:: MBReview PriBench ::..

PriBench v1.04 is much like SuperPi in that it is computationally intensive; however PriBench relies heavily on arithmetic performance. PriBench is a system level benchmark, and relies solely on the performance of the processor and memory subsystem. Unlike many of today’s synthetic benchmarks which rely on other aspects such as hard drive speeds, etc. PriBench does not rely on any “exterior” devices for the tests. PriBench was coded in house and utilizes a computationally intensive algorithm to compute primes well into the 100’s of millions for the current version. The program is extremely precise as we have seen time fluctuations of around +/- .03 or so seconds. For this review, I chose to run the two most intensive tests available.

On the PriBench front, we can clearly see that even with the added FSB speed, and the added memory bandwidth, we don’t see much of a performance gain. This can be explained in simple terms. PriBench is used to measure the arithmetic capabilities of the processor and the memory subsystem. Now, the amount that it relies on the memory subsystem is rather small as the majority of the test relies solely on computational capabilities. Given that this is still the “Northwood” core, and is only slightly faster the its predecessor, the performance jump, in theory, shouldn’t be that large. This is exactly what we found.

..:: ScienceMark 2.0::..

Next in line for our benchmarking results, we find ScienceMark 2.0. For these benchmarks, we decided to take a look at the performance results achieved with one of the built-in programs, MemBench. We’ll start off with the bandwidth results. Once again, we’re seeing the type of results we’d expect to see when we’re given a 266MHz boost on the Front Side Bus. The new i925XE / 3.46GHz EE combination is able to easily put the older i925X / 3.40GHz EE in its dust. With this boost in FSB speed, the EE’s are finally able to put up similar bandwidth scores to the “Prescott” core processors. The “Prescott” core features improved memory handling making it superior to the “Northwood” core. This new boost levels the playing field, albeit it, one expensive field.
