Forget about AMD in the CPU performance arena — that fight has a clear winner as these reviews from AnandTech and The Tech Report clearly state. Even AnandTech agrees which was why they only spent one page talking CPU performance.
They decided to dedicate a vast majority of their review on the integrated graphics performance. The HD 4000 shows a significant improvement over its predecessor which should make for better Ultrabooks and Macbook Airs. But as significant as an improvement the HD 4000 is, it could have been even more substantial if Intel didn’t hold back and dedicated a little bit more die space for their graphics processor.
A little faster, consumes less power, improvements to the integrated graphics and all without increasing prices? A winning product all around.
