28nm Qualcomm Snapdragon Chip Not As Power Efficient Says Research Firm

The HTC One S, which is the company's mainstream alternative to the Samsung Galaxy S2, comes with the first Qualcomm Snapdragon chip based on a 28nm manufacturing process.

The MSM8260A is clocked at 1.5GHz like the MSM8260 but manages to outperform it by as much as 25 per cent in CPU performance benchmarks (thanks to the new Krait architecture) according to a report by ABI Research while delivering a smaller die size and a lower manufacturing cost.

Both models however use the same Adreno 225 GPU core which means that, unlike the transition from the A5 to the A5X, the GPU performance will remain the same.

However, the battery life did not improve with the battery drain in line with the MSM8260 and video encoding performance worse - this could be due to a lower clock speed on the GPU. The cores themselves, according to ABI Research, were drawing 33 per cent less power but were not as power efficient as they expected for a jump from a 45nm to a 28nm manufacturing process.

The HTC One S is essentially a souped up Sensation XE and sells for around £380 in the UK and runs on Android 4.0.3 Ice Cream Sandwich with HTC Sense 4.0 on it. The top of the range handset from HTC is the HTC One X which costs around 15 per cent more but comes with a quad core processor and a full HD display.
