As usual, we will first run synthetic benchmarks.
The SiSoftware 2007 suite features an updated enhanced-functionality interface, runs on three platforms (Win32 x86, Win64 x64, WinCE ARM), contains 13 tests, 34 informational modules, and supports a large range of devices thanks to the developer’s collaboration with Intel, AMD, ATI, SiS and VIA. The program is supported in six languages and has a free Lite version for personal and educational purposes.
PCMark 2005 carries on the tradition of complex benchmarks of the series and uses fragments of real-life applications as tests. This makes it somewhat more relevant for end-users as opposed to fully synthetic benchmarks. After running a series of 11 tests on the different components of the system, the program calculates an overall performance score in units called PCMarks. PCMark 2005 can check out a computer at processing HD video and encoding audio, and offers enhanced tests of the CPU and hard disk under multi-threaded load. The overall score is calculated by the formula: PCMark Score = 87 x (the geometric mean of the basic tests), where the geometric mean is calculated as (Result 1 x Result 2 x…)/the number of results.
SiSoftware Sandra measures the overall performance of the system as well as that of each of its subsystems, while PCMark benchmarks the computer performance in office and office-related applications and also produces performance scores for the main subsystems (CPU, memory, graphical, and disk subsystem).
Let’s first discuss the numbers we’ve got in the good old SiSoftware Sandra 2005 and PCMark 2004. The superiority of the Merom CPU over the Yonah is not to be doubted here. The Core 2 Duo is ahead even when the two CPUs work at the same frequency of 1GHz in the battery-saving mode. That’s the result of changes in the micro-architecture.
We couldn’t complete the CPU test when the notebooks were powered from the mains. PCMark 2004 is not a new application and Futuremark has ceased to support it with patches. Perhaps this is why the Merom couldn’t pass the obligatory Grammar Check as is indicated in the next screenshot:
Note also that the memory and graphics subsystems have got higher scores, too, thanks to the new CPU core. The good result of the HDD test is due to the high spindle rotation speed of the HDD installed in the Inspiron XPS M1210.
SiSoftware Sandra 2007 and PCMark 2005 agree with the previous versions of the same benchmarks in general, but you can note that the result of SiSoftware Sandra’s multimedia test is much higher in comparison with an average Core Duo. It’s because the Merom has got 128-bit SSE subunits.
