The 3DMark Fire Strike Ultra benchmark produces a 3DMark Fire Strike Ultra score, a Graphics test sub-score, a CPU test sub-score, and a Combined test sub-score. The scores are rounded to the nearest integer. The better a system's performance, the higher the score.
3DMark Fire Strike Ultra score
We use a weighted harmonic mean to calculate the 3DMark Fire Strike Ultra score from the Graphics, Physics and Combined test scores.
3DMark Fire Strike Ultra score = (W_graphics + W_ physics + W_combined) / (W_graphics / Sgraphics + W_physics / S_physics + W_combined / S_combined) Where: W_graphics = The Graphics score weight, equal to 0.75 W_physics = The Physics score weight, equal to 0.15 W_combined = The Combined score weight, equal to 0.10 S_graphics = Graphics score S_physics = Physics score S_combined = Combined score
For a balanced system, the weights reflect the ratio of the effects of GPU and CPU performance on the overall score. Balanced in this sense means the Graphics, Physics and Combined scores are roughly the same magnitude.
For a system where either the Graphics or Physics score is substantially higher than the other, the harmonic mean rewards boosting the lower score. This reflects the reality of the user experience. For example, doubling the CPU speed in a system with an entry-level graphics card doesn't help much in games since the system is already limited by the GPU. Likewise for a system with a high-end graphics card paired with an underpowered CPU.
Graphics score
Each Graphics Test produces a raw performance result in frames per second (FPS). We take a harmonic mean of these raw results and multiply it by a scaling constant to get the Graphics score (S_graphics). The scaling constant brings the score in line with traditional 3DMark score levels.
S_graphics = 230 × 2 / (1 / F_gt1 + 1 / F_gt2) Where: F_gt1 = The average frame rate in FPS from Graphics Test 1 F_gt2 = The average frame rate in FPS from Graphics Ttest 2
Physics score
S_physics = 315 × F_physics Where: F_physics = The average frame rate in FPS from the Physics Test
The scaling constant brings the score in line with traditional 3DMark score levels.
Combined score
S_combined = 215 × F_combined Where: F_combined = The average frame rate in FPS from the Combined Test
The scaling constant brings the score in line with traditional 3DMark score levels.
