Performance Summary

To formulate our performance metric we use a weighted average method and each benchmark test gets a weight of 1 out of a total calculation with 9 weights (meaning all resolutions and variations of the same test are only ever one weight). Compute tests, power consumption, temperatures and acoustics are not included in the weighted calculation. The 9 weights are 1 for each test we so that means 6 games (listed below) and 3 benchmarks (also listed below). We calculate the relative score for each card in each test by dividing the cumulative average frame rate or score of each card by the average cumulative average frame rate/score from all the graphics cards in group. We then take those 9 relative scores and average those for each card, before dividing those averages by the average of the card being reviewed in the test so that the value of the card being reviewed is 1 and every other card’s performance metric is in relation to it. The end result are numbers that vary around 1 with 0.5 being half the performance of the tested card and 2 being double the performance of the tested card. We then convert those numbers into percentages to make them more readable so 1 becomes 100% and 0.5 becomes 50%.
