..:: 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 the 560 Pentium 4 has a substantial lead over that of the older “Northwood” core Extreme Edition processor, even with the huge L3 cache available to it. The “E” processors are all able to easily overtake their clock for clock competition, as well as all speed grades above. We first saw this impressive performance during our initial look at “Prescott” and once again it has shown that Intel has made some solid improvements to the mathematical portion of the Netburst Architecture.
..:: 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. The MemBench bandwidth tests tell a familiar story, “Prescott” is able to easily best the “Northwood” based Extreme Edition CPU for overall bandwidth. One area where the Extreme Edition has an advantage is in the cycles and latency results seen above. The Extreme Edition is able to fetch a larger chunk of data quicker, and with less latency than the “Prescott” counterpart. The Extreme Edition also poses results to us that show the latency and cycles needed to complete the operation decreasing at a quicker rate than that of the “Prescott” core.
