Intel Core i7-11800H trades blows with AMD Ryzen 7 5800H in CPU-Z benchmark comparison and wins by a nose

Benchmarks for the Intel Core i7-11800H have been shared, and it seems the Tiger Lake H45 laptop processor is quite a contender. The i7-11800H’s nemesis is likely going to be the AMD Ryzen 7 5800H, which has similar key specs to the Intel rival but a lower max boost clock rate. In a CPU-Z comparison, the chip from Team Blue has the slightest of edges.

Intel Core i7-11800H laptops have started popping up here and there, so it’s no surprise that benchmark results for the Tiger Lake H45 chip have also been unearthed. Noted data-miner APISAK has shared one particularly interesting CPU-Z result that gives a good idea of what can be expected from the Intel processor, especially when compared to a Zen 3 Cezanne part in the form of the AMD Ryzen 7 5800H. Both processors have 8 cores and 16 threads for processing business, and they can both rely on max 45 W TDP (configurable by vendor).

The Intel Core i7-11800H does have an advantage in terms of maximum boost clock rates: 4.6 GHz (single core) vs. 4.4 GHz. This obviously helps with the CPU-Z single-thread benchmark, where the Tiger Lake H45 chip scores 615 points. The Ryzen 7 5800H doesn’t fall too far behind though, scoring 585 points, leaving the Intel processor with a +5.13% advantage here. In the past, you could have expected the AMD chip to really blow the Intel part out of the water in the multi-core discipline, but just like AMD has improved single-core performance with its Zen 3 microarchitecture, it seems Team Blue has been tweaking multi-core power with its products.

So the AMD Ryzen 7 5800H scores 6,015 points in CPU-Z’s multithread run while the i7-11800H keeps up on 5,802 points, resulting in +3.67% advantage for the part from Team Red. An unbiased consumer would likely be more tempted by the laptop (seemingly from the Chinese ThundeRobot company) with the Intel Tiger Lake processor based on this performance comparison. A personal view of how important single-core/single-thread performance is compared to multi-core/multithread processing doesn’t matter here though, as the real winner in this situation is actually the laptop buyer, who can choose either similarly performing product based on their own core-performance preference.
