Performance and Benchmarks
HP offers the new TouchSmart tm2t with a range of Intel processors but the 1.2GHz Intel Core i3-330UM processor in our review sample offers some pretty impressive performance. The synthetic benchmark tests show the Core i3 processor in the tm2 easily out performs many thin and light notebooks with CULV processors, and it certainly is a major step up from netbooks or budget tablets equipped with the Intel Atom processor. Multitasking in Windows 7 is snappy and applications launch without any noticeable lag beyond what you expect from standard hard drive access times.
The bigger news here in terms of overall performance is the 512MB ATI Mobility Radeon HD 5450 switchable graphics. The tm2 gives users the option of using a high-performance dedicated graphics processor when watching HD video or playing games or you can manually switch to using the low-performance Intel integrated graphics which consume less power when you need to maximize battery life.

Heat and Noise
The TouchSmart tm2 does an acceptable job keeping heat under control. The system fan and heatsinks in the notebook do their job managing heat when the system is under load … as we discovered when we ran multiple benchmarks back to back. This tablet doesn’t generate anywhere near as much heat on the exterior of the laptop and the cooling fan remains almost perfectly silent except for times when the CPU and GPU are under heavy stress (such as benchmarking or playing high-end games).
The tm2’s overall battery life performance is a nice step up from the previous tx2. The old tx2 delivered a little more than 3 hours in “balanced” power mode with Wi-Fi on. The new TouchSmart tm2 was able to keep running for 5 hours and 32 minutes in the same Windows 7 “balanced” power mode with screen brightness set to 70 percent and Wi-Fi switched on. As an interesting side note, I forgot to turn off the tablet during the review period and discovered it managed to keep running in hibernate mode (screen off and most hardware turned off) for more than one week!
