The tablet will probably feature Qualcomm’s third-generation MSM8660 chipset clocked at the impressive 1.5GHz and if that doesn’t mean much to you, why don’t you check out the benchmark cracking performance of the dual-core MSM8660 silicon demoed by the company mere weeks ago? Real-life scenarios of using the silicon muscle include handling 1080p full HD videos and HTML5 playback, which both ran without a hitch. Unfortunately, we run into a paradox here because out of the whole MSM8x60 family of processors, only the MSM8960 chipset supports LTE connectivity. Will the HTC Puccini rely on AT&T's HSPA+ network instead of using its future LTE pipelines?
Bear in mind that all this information is preliminary and that the tablet's final hardware profile might undergo some changes. We will keep our fingers crossed in hope of hearing a solid confirmation from HTC soon.
