A look at the Qualcomm MSM7227 chipset in HTC Trophy, Tera and Photon

HTC Photon


HTC’s new generation of upcoming Windows Mobile handsets, the HTC Trophy, HTC Tera and HTC Photon are all powered by the 600 Mhz Qualcomm MSM7227 processor. Disappointingly these are not part of Qualcomm’s next generation Snapdragon family, but rather just the next in the MSM72xx series.

Of course the advantage to HTC of these processors are that they are the same size as the older generation, near pin compatible, and software compatible with the older MSM7225 processor, meaning time to market was faster.

The processor is also a real upgrade to the older generation, with an integrated Floating Point Unit (whether the OS will make use of it is another question) and a Level 2 cache, which should again significantly increase speed.  The processor also uses less power than the MSM7225, meaning either longer battery life, or more likely for the next-gen of Windows Mobile handsets, smaller form factors.

I have collated the information available about the 3 tiers of chipsets below.  There are some gaps obviously, but I believe our very intelligent readers will not mind helping to fill these in, and possibly suggest a few more rows.

The conclusion however is that while the MS7227 processor is not ground breaking, it should not be as much of a slouch as the original MSM 7200 HTC Tilt was.
