Productivity Benchmarks

Starting with Cinebench and it’s good news for the i7-8750H, as it obliterates the 7700HQ to the tune of 58 percent in the multi-threaded test.

When you add in 50 percent more cores and increase the clock speeds of these cores, this is the sort of result you can expect in a best-case scenario. The 8750H also provides nine percent more performance in the single-threaded test, which is just shy of the 11 percent single-core turbo clock speed increase.

Gains in performance of around 50 percent are typical for a lot of workloads. While performing a 2-pass x264 encode, the 8750H was 46 percent faster than the 7700HQ, which is a significant difference for a rendering test. You won’t get quite the same performance uplift when rendering x265 videos in Handbrake, but we still achieved a 34 percent gain here with the 8750H, which is significant.

In the Excel Monte Carlo workload, the 8750H was almost exactly 50 percent faster than the 7700HQ; another strong result for the six-core CPU that will please those that work with large, calculation-heavy spreadsheets.

Compression and decompression is a huge win for the 8750H. In 7-Zip, the 8750H is 55 percent faster than the 7700HQ in compression, and a huge 69 percent faster in decompression. It’s a similar result in WinRAR, where the 8750H was 53 percent faster in its compression-heavy benchmark. The 8750H even outperformed the 7700HQ in WinRAR’s single-threaded test to the tune of 15%.

Moving on to our Adobe Premiere benchmark, which utilizes both the CPU and GPU. In this test, the 8750H was 25 percent faster at rendering a video with Lumetri effects than the 7700HQ when using a laptop with the same GPU inside.

The only benchmark that showed effectively no performance difference is MATLAB. As a largely single-threaded test that favors high memory bandwidth, the lack of improvements to the memory controller could have limited any performance gains in this workload.

Most PCMark tests are single-threaded, so it’s no surprise to see single-digit performance gains in this workload. In the older PCMark 8 Home test, the 8750H was 8 percent faster than the 7700HQ in a system with the same GPU. That narrowed to 6 percent in the Creative workload, though it did grow to 12 percent in the Work test, and 9 percent in the newer PCMark 10.

If you’re interested in memory bandwidth, there is no real difference between the 8750H and the 7700HQ. Both support up to DDR4-2666, and with a dual-channel configuration you’ll get around 25 GB/s of bandwidth. Cache performance, however, is significantly improved across the board.

The final test I’ll mention before moving to the gaming benchmarks is 3DMark’s Time Spy test. While the overall score is just 11 percent higher than a system with the same GPU, the CPU score is a good 52 percent higher as expected, which helps provide most of this overall score improvement.
