Here’s where things get interesting, the mobile H-Series processors. CPU clocks are down slightly relative to the above M-series, and all of these are 6MB L3 cache parts. To make up for that, Intel has equipped the top three HQ parts with their Iris Pro 5200 iGPU. While having faster integrated graphics may not really matter much on a desktop if you have a discrete GPU, on notebooks we generally always like having the faster iGPU available—you don’t always need a full discrete GPU for some tasks, but the cut-down GT1 of the previous generation sometimes fell short. Heat and noise are also more of a concern with notebooks, so running off the iGPU whenever possible is generally a good thing.
Intel has targeted roughly the level of performance offered by NVIDIA’s GT 650M with their Iris Pro 5200 graphics, or roughly a two-fold increase in performance over HD 4000, and that should be enough for everything short of high-quality, high-resolution gaming. What’s even more interesting is that there’s the potential for a reasonable gaming experience with the CPU and iGPU combined still drawing less than 47W of power; GT 650M may still be a better gaming chip, but the combined CPU + dGPU power draw is quite a bit higher than 47W. Of course, even on a 90Wh battery a load of 45W means you’d still get less than two hours of battery life. We’ll see about testing this as soon as we get more time with the hardware.
