Intel Core i7-12800H vs Intel Core Ultra 7 155H

Core i7-12800H vs Core Ultra 7 155H comparison

In our benchmarks, the Core i7-12800H beats the Core Ultra 7 155H in overall performance. Despite this, the Core Ultra 7 155H has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core Ultra 7 155H has slightly more cores with 16 cores compared to the Core i7-12800H that has 14 cores. It also has more threads than the Core i7-12800H. With our hardware info, we find that the Core i7-12800H has a significantly higher clock speed than the Core Ultra 7 155H. In terms of cache, the Core Ultra 7 155H has significantly more L2 cache when compared to the Core i7-12800H. However, both these chips have the same amount of L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-12800H has more threads than cores. Each physical core is split into multiple threads.
