PCMark Score
PCMark05 scores will initially range between 1,200 and 5,500 PCMarks with generally available PC hardware.
They are scaled such that an entry-level system will score approximately 1,200 PCMarks and a high-end
system, at the time of product release, will score approximately 5,500 PCMarks. Of course, we expect that over
timw there will be PCs that will score higher and higher.
Figure 6: Example PCMark05 Scores
The PCMark score is calculated by using the results of the various tests in the systems test suite. The individual
test scores are combined using a geometric mean. The geometric mean provides a fair mechanism to combine a
large number of test results as compared to assigning arbitrary weights to individual scores. Geometric means
are used in other successful benchmarks such as those from SPEC. The geometric mean is scaled using results

from reference systems to produce the appropriate range of scores. The general formula for the geometric mean
is: geometric mean = (item1 * item2 * item3 * item4)
[1/number if items]
.
The formula for the overall PCMark score is:
PCMark Score = 87 × [geomean of the System test suite test results]
CPU Score
The CPU score is also the geometric mean calculated from the CPU suite test results. The scaling factor is
created in a same manner as for the PCMark score. The CPU score formula is:
CPU Score = 82 × [geomean of the CPU test suite test results]
Memory Score
The memory score is also calculated from the memory suite test results using a geometric mean. The scaling
factor is created in a same way as for the PCMark score. The Memory score formula is:
Memory Score = 1.7 × [geomean of the Memory test suite test results]
Graphics Score
The PCMark05 Graphics score is calculated also using the geometric mean. The formula used is:
Graphics score = 17 × [geomean of the Graphics test suite test results]
HDD Score
As in the other test suites, also the HDD Score is calculated using the geometric mean:
HDD Score = 300 * [geomean of the HDD test suite test results]
