When we heard HP was building its latest TouchSmart with Intel’s Core i7 processor, we figured it was game-over for the competition: Lenovo and Sony use quad-cores, too, but they both tapped Intel’s Core 2 Quad. MSI picked an even less capable Core 2 Duo (and priced its machine accordingly). But when the benchmarking dust had cleared, HP sat in third place across the board. What happened?
We should have remembered that HP likes to use mobile processors in its TouchSmart line. In this case, a 1.6GHz Core i7-720QM. That’s a capable enough proc, but the older (and cheaper) Core 2 Quad that Lenovo and Sony picked is a desktop model running at 2.66GHz. So even the larger cache, integrated memory controller, Hyper-Threading, Turbo Boost technology, and other goodies tucked inside the Core i7-720QM don’t compensate for the mobile proc’s lower clock speed.
