Intel Xeon X5365 V8 Performance Review

By Vince Freeman :  October 2, 2007

WinRAR 3.62 Performance

WinRAR is one of the most popular compression programs, and it even includes an internal benchmark program that measures the performance of the RAR compression and decompression algorithm using a demanding worst-case data set. This multi-threaded test offers a data throughput rating, and while it does not relate specifically to cache or memory transfers, we have found that the overall throughput numbers do adhere closely to the overall architecture. A faster clock speed certainly helps, but the score also ties in closely with memory, cache and CPU performance.

WinRAR is an interesting test, as not only is it multi-threaded, but also takes into account memory bandwidth and overall system performance. The memory bandwidth part of the equation seems to be even more important than we previously suspected, and the Xeon X5365 V8 can't keep up with the Core 2 quad-core models equipped with DDR2-800.

TMPGEnc Xpress 3.0 MPEG-1 Encoding Performance

TMPGEnc Xpress 3.0 is a very popular and powerful MPEG encoder, and a program that not only provides real-world video encoding performance results, but also includes a host of specialized CPU support options. The program supports virtually all CPU multimedia features such as MMX/MMX-2, SSE/SSE2/SSE3, 3DNow!, along with multi-core and Hyper-Threading technologies.

Due to the increasingly high performance of multi-core processors, our reference video is now a higher-end, 7-minute AVI file. In our first test, this file is then encoded it to MPEG-1 using TMPGEnc and the encoding time is recorded. The results are expressed in the form of time elapsed (minutes: seconds) and unlike our other benchmarks, a smaller bar denotes less time taken, and therefore better encoding performance.

As we've already broken the 1-minute barrier, and because MPEG-1 encoding is not exactly the most stressful on a CPU, we don't expect miracles - even for the Xeon X5365 V8. The overall results are quite good, and the 8-core system broke our previous record, and even descended below the 45-second mark, setting a new performance record in the process. These time gaps may not seem like much, but remember we're only talking about a 7-minute file using basic MPEG-1 encoding, and relative positioning is still the most important factor.

TMPGEnc Xpress 3.0 MPEG-2 Encoding Performance

For the next test, we've taken the same 7-minute video file, and encoded it to MPEG-2 using TMPGEnc Express 3.0. This is more stressful on the system than our previous MPEG-1 encoding, and is the standard for DVD authoring. The performance results are expressed in the form of time elapsed (minutes: seconds) and as with the MPEG-1 results, a smaller bar denotes less time taken, and therefore higher performance.

The MPEG-2 encoding is much a tougher test, stressing even multi-core processors, and we see improved results for the 8-core Xeon X5365 V8. It easily speeds by the dual and quad core competition, and there is now a noticeable gap between the Xeon X5365 V8 and the rest of the Intel and AMD desktop processors.
