A Nenamark benchmark has surfaced for the rumoured Sony LT29i handset codenamed ‘Hayabusa’. Interestingly, the benchmark says that the LT29i tested is using the Qualcomm Adreno 225 GPU, which would mean that it is running the S4 Snapdragon chipset (MSM8960 perhaps?)
This would also concur from news earlier today that Sony Mobile was looking to release a phone based on Cortex-A15 in H2 2012. Whilst the S4 Snapdragon is not strictly the same, performance is said to be similar.
Other information gleaned from the benchmark include a 1.5GHz dual-core processor, and strange 720 x 1196 resolution display (we imagine this is some bug, the final handset should run at 720 x 1280 resolution). The handset tested was running Android Ice Cream Sandwich 4.0.3.
Update: As pointed out in the comments, the lower vertical resolution is most likely down to the fact that part of the screen real estate is being used for on-screen buttons (much like the Galaxy Nexus). This would mean that the Sony LT29i ‘Hayabusa’ would be the first Sony Mobile handset without any physical or capacitive buttons. [Thanks Reptile1980 & Cholek3!]
