The Intel Skull Canyon NUC with its Core i7-6770HQ and 128MB of embedded DRAM leads the pack by a hair. It also takes a long time to run, so machines that can’t handle the heat will show performance issues. Like CineBench R15, it’s a pure CPU test and loves multiple cores. Our encoding test uses the free and popular program Handbrake to convert a 30GB 1080p video file using the Android Tablet preset. The Alpha R2’s quad-core Skylake CPU holds it own against a full desktop quad-core processor, as well as Intel’s fancy-pants Skull Canyon NUC. The older Haswell chip wins here by a little bit, thanks to its higher wattage and higher clock speed-even though it’s the oldest CPU. It’s a great way to see how a machine’s processor stacks up, as it favors those with more CPU cores. Here’s the Alpha R2 compared to Intel’s nifty little Skull Canyon NUC with a quad-core Skylake processor, the original Alpha with a dual-core Core i3 chip, and our PCWorld zero-point desktop with a 4th-generation Haswell Core i7 CPU.ĬineBench R15 is a quick benchmark that measures a PC’s ability to render 3D scenes. The back of the Alpha R2 gives you an optical S/PDIF audio port, two USB 3.0 Type A ports, gigabit ethernet, HDMI 2.0 out, HDMI In, and a port that supports Alienware’s Amplifier GPU enclosure. In practical use, the Alpha R2 is pretty fast.
The good news is the Core i7-6700T has a healthy Turbo Boost of 3.6GHz, so the performance disparity isn’t quite as big as you’d think.
Here are all three CPUs available for the Alpha R2, lined up with a Core i7-6700K for context. The base speed on a Core i7-6700K is 4.0GHz, while the Core i7-6700T’s is 2.8GHz. To drop from 91 watts to 35, you give up a lot of clock speed.
