The Core i7-7700HQ is Kaby Lake’s top-shelf direct successor of the Skylake Core i7-6700HQ offering slightly higher clock speeds on the almost identical architecture and TDP. While Intel markets Kaby Lake’s architecture as “14nm+”, the Core i7-7700HQ is still on the same 14nm node with the only significant update being in the iGPU department. That’s why the slightly altered clock speeds (2.8 – 3.8 GHz vs 2.6 – 3.5 GHz) bring not more than 10% increase in performance compared to the Core i7-6700HQ. We still have the supported Hyper-Threading technology with 4/8 – core/thread design, the same 45W TDP and 6MB cache.
However, the Kaby Lake generation boasts an updated video engine for the iGPU, although, its performance is just about the same. Branded as Intel HD Graphics 630, the GPU offers slightly higher clock speeds (350 – 1100 MHz vs 350 – 1050 MHz) compared to the Intel HD Graphics 530 and support for H265/HEVC Main10 profile at 10-bit color depth and the VP9 codec for full hardware acceleration. In addition, the HDCP 2.2 is also supported allowing Netflix’s 4K video streaming.
