Custom 0405 vs Core Ultra 5 125U comparison

According to the hardwareDB Benchmark tool, the Core Ultra 5 125U is faster than the Custom 0405. Despite this, the Custom 0405 has the advantage in our gaming benchmark.

With info from our database, we find that the Core Ultra 5 125U has significantly more cores with 12 cores whereas the Custom 0405 has 4 cores. It also has more threads than the Custom 0405. With our hardware info, we find that the Core Ultra 5 125U has a slightly higher clock speed than the Custom 0405. In terms of cache, the Core Ultra 5 125U has significantly more L2 cache when compared to the Custom 0405. The Core Ultra 5 125U also has significantly more 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 Custom 0405 has more threads than cores. Each physical core is split into multiple threads.
