Intel Xeon X5365 V8 Performance Review

By Vince Freeman :  October 2, 2007

Benchmark Analysis

The benchmark analysis held very few surprises, and the Xeon X5365 V8 is an extremely fast performer in the multi-threaded tests, setting record after record in this area. The speed this platform attained in some benchmarks was simply amazing, and it simply devoured heavy-duty tasks like video encoding and CINEBENCH 9.5. The reliance on DDR2-667 memory did lower the memory scores, but once again, this was to be expected. The gaming performance results showed off the potential of the Xeon X5365 V8 when ultra high-end, multi-threaded games do come along, but for the current crop, it seems that 8-core processing doesn't offer a lot more compared to current 4-core CPUs. Overall, this platform displayed very impressive performance levels, and the Xeon X5365 V8 offers a significant performance advantage in media creation and multi-threaded applications, while not losing anything on the gaming side.

Total System Power Consumption Testing

The power consumption of desktop systems is a definite concern, especially for a dual-CPU, 8-core system like the Xeon X5365 V8. The Xeon processors may be 65nm, but at a TDP of 120W, these are not power misers. As we are testing a dual-CPU system, using top of the line 3.0 GHz Xeon X5365 processors, power consumption is expected to be high, and when taking the Intel S5000XVN workstation motherboard into account, possibly as great as double that of a standard desktop PC.

In order to measure power consumption, we took each of the AMD and Intel reference systems, ran the outlet through a Power Analyzer, and then compiled total system consumption figures (in Watts) for Idle and Load scenarios. In order to keep the systems and results consistent, we used the same configuration for the AMD and Intel processors as listed on the Test Systems page.

The first test measures the total system power usage when the AMD and Intel processors are set to power-saving mode. For AMD, this means enabling Cool'n'Quiet, while for Intel we need to activate Enhanced SpeedStep. The test was performed after the operating system has loaded, and all of the various software and hardware components have initialized and we hit a consistent power reading. We are not surprised by these results, which show the Xeon X5365 V8 system with power consumption totals well in excess of the other single-CPU systems.

The second test was also performed at idle, but this time under the same scenario that many users employ, with the processors operating at default clock speeds with no power savings enabled. This is performed by manually selecting the clock multiplier in the BIOS and disabling any BIOS and Windows power-saving features. The Intel processors do not show very much change compared to the AMD competition, but the Xeon X5365 V8 naturally has the highest consumption once again.

The third test changes the operating conditions from Idle to Load, and the SANDRA XI Multimedia CPU benchmark pushes processor usage to 100%, while ensuring that no extraneous hard drive or peripheral activity artificially ramps up the power consumption rates. The results using SANDRA are also incredibly consistent, with the wattage numbers remaining stable through the entire test. Once all the processors are humming at peak usage, we see the power consumption numbers start to increase, especially the quad core models. It's even more apparent with the 8-core Xeon X5365 V8, which posts significantly higher numbers.

Please keep in mind that these numbers relate to total system power consumption, of which the CPU is only one part. In evaluations like this, relative placing is more important than the base numbers, which can change based on the platform and peripheral mix.
