Geekbench 3 is one of the better benchmarks out there for comparing mobile CPU performance. It contains a variety of tests and reports a cumulated single-core score, and a multi-core score. One way of analyzing processors is to get an idea of per-cycle performance. For this, I took the single-core scores for various processors and divided by the reported clock frequency to obtain the following metric: Geekbench 3 Single-core score/ GHz.
I report the results in the table below. There can be many implementations of a given ARM core in different chipsets, and the same chipset can also perform slightly differently in different devices. I report the device from which I got the scores. Even so, computations are very approximate and based on rough averages of geekbench 3 scores from different users as reported on the Geekbench browser.
Here it is:
| CPU core | Device(s) | Score/GHz |
|---|---|---|
| Cortex A7 | Moto G | 280 |
| Scorpion | Galaxy S2 X (T989D) | 250 |
| Cortex A9 | Galaxy S2 (i9100) | 290 |
| Krait 200 | HTC One S, Xperia ZL | 330 |
| Krait 300 | Moto X | 390 |
| Krait 400 | Nexus 5, LG G2 | 405 |
| Cortex A15 | Nvidia Shield | 480 |
| Apple A6 | iPhone 5c | 540 |
| Apple A7 (32-bit) | iPhone 5s | 800 |
| Apple A7 (64-bit) | iPhone 5s | 1050 |
Note that for Scorpion, reported frequency was 1.5GHz but I have never seen it go above 1.242 GHz on some devices I used previously so I used 1.242GHz as the frequency.
