Intel Core i5-7600K Kaby Lake Processor Review

IGPU, IGPU + GPU Benchmarks
Theoretically, Intel iGPUs can combine with a discrete graphics card to achieve better performance using the latest DirectX 12 API. Unfortunately, the parallel queues feature and cross adapter support is non-existent at the moment. I’m hoping development studios will acknowledge the performance benefits this can bring to the table and work on implementing the proper multi-adapter functionality. Sadly, even discrete dual-GPU scaling is dreadful in most DirectX 12 titles so this is something which could take some time to become widely adopted. Of course, you don’t have to use a discrete graphics card and it’s possible to rely on the iGPU. Intel’s HD Graphics 630 solution is better than the previous offering but it’s still underpowered.
The i5-7600K’s iGPU records a relatively decent 3DMark Fire Strike score and enjoys a good lead over the i7-6700K. Overclocking the CPU doesn’t make a huge difference and I couldn’t find any settings to adjust the iGPU directly.
On a similar note, the i5-7600K can contend with Dirt Rally’s low preset and maintain a perfectly playable user experience. Actually, the graphics don’t look that bad and I could easily invest time on Dirt Rally using the iGPU without any problems.
Tomb Raider on the lowest preset doesn’t look very appealing but this is needed due to the weak nature of integrated graphics options. Despite the atrocious visuals, the i5-7600K reported an excellent frame-rate and didn’t drop below the 40 mark. This is a good improvement over the previous generation i7-6700K and illustrates the steps forward Intel have made.
