The HTC One M8 and the Samsung Galaxy S5 are among the very few handsets to pack the new Snapdragon 801 chip with (MSM8974). We did the usual benchmark tests on the HTC One M8 and compared it with the Galaxy S5 we had on hand.
On paper, the Samsung Galaxy S5 has the slightly better chip — an MSM8974-AC which has a maximum clock speed of up to 2.45GHz, while the HTC One M8 that we have uses an MSM8974AB which only goes up to 2.36GHz. (Note: Antutu, 3DMark and Quadrant are all showing our unit as having MSM8974AB but with max clock speed of 2.45GHz, which could be a detection error).
Quadrant Standard: 25,169 (HTC one M8) vs. 25,402 (Galaxy S5)
Antutu Benchmark: 38,769 (HTC One M8) vs. 36,212 (Galaxy S5)
Nenamark 2: 59.3fps (HTC One M8) vs. 59.9fps (Galaxy S5)
Vellamo: 1,804 (HTML5), 1,300 (Metal) [HTC One M8] vs. 1,626 (HTML5), 1,204 (Metal) [Galaxy S5]
The benchmark scores looked pretty interesting as the Galaxy S5 won in Quadrant and Nenamark2 while the HTC One M8 won in Antutu and Vellamo.
