We’ve been hearing a lot about Intel’s 10th Gen Comet Lake-S and H chips lately. They will consume a lot of power, run hot and offer marginal performance gains. That’s the thin and thick of it. Compared to AMD’s new Ryzen 4000 APUs, the Comet Lake-H CPUs don’t hold up particularly well. While the single-threaded performance is mostly on par and at times slightly higher, the multi-threaded performance falls short by a fat margin. Today we’ll be having a look at the Geekbench 4 and 5 benchmarks of the Ryzen 7 4800H and the Intel Core i7-10750H, and see how the two chips stack up.
Before we start, yes, these aren’t definitive real-world benchmarks, but Geekbench scores have repeatedly proved to be a good indicator of overall performance.
Here, we’ve got the Geekbench 5 scores of the Core i7-10750H and the Ryzen 7 4800H. In this benchmark, the latter is faster in both the single-core and multi-core segments. While the delta in the SC test is negligible at best, the multi-core is a significant 50% deficit.
Here’s something interesting though. There will be certain devices with slightly faster single-core performance on account of higher boost clocks. Such as:
This is a Lenovo laptop featuring the same CPU running at a higher operating frequency. While the previous chip had a boost clock of around 4.7GHz, this part might be able to get to 5GHz+. This can be explained on the basis of a better thermal solution which often makes the laptop bulkier. Note how the first one is an MSI GS66 Stealth, a device known for its lightweight form-factor. Considering the limitations, it runs at a tamer operating clock that the latter. I suspect this will be the case with most laptops. Throttling and thermal restrictions will keep the higher end Comet Lake chips from running at 5GHz at sustained intervals. Let’s have a look at the detailed single-core scores now:
The Intel CPU has an advantage in INT based operations such as Speech Recognition, Machine Learning, N-Body Physics, and Text Compression while the Ryzen 7 4800H is faster in crypto and floating-point instructions.
We have a Geekbench 4 score to examine:
The results are mostly unchanged. The Comet Lake-H based Core i7-10750H gets a higher single-core score while the Ryzen 7 4800H leads in the multi-core benchmark. On a closer look, we can see that the latter once again has an advantage in the Crypto-tests while the former performs better in INT-based instructions. In floating-point arithmetic, the two are apparently on par with each other. This can be explained on the basis of Zen 2’s improved AVX256 capabilities which allows native execution of 256-bit AVX instructions.
