I guess overclocking dual-core CPUs in mobile phones to 1.5GHz is normal now a brave soul pushed the Tegra 2 chipset inside their T-Mobile G2x to the breakneck speed, 50% up from the stock frequency. A week ago we saw a Galaxy S II reach 1.5GHz though the G2x manages to beat its score at some benchmarks.
The T-Mobile G2x was running CyanogenMod 7 with a custom kernel the Trinity CM7 EXT4 1.5GHz kernel. It posted a whopping 4570 score on Quadrant, while on stock frequencies (1GHz) it only does around 2400. The switch to EXT4 probably contributes a good portion of that sizable increase though, its not just the CPU.
Others using the same kernel have reported Linpack scores of 54 up from the 36.85 we got from our Optimus 2X at stock speed. Thats major improvement in pure CPU performance.
