Ryzen 9 6900HX vs Ryzen 7 PRO 7840U comparison

According to the hardwareDB Benchmark tool, the Ryzen 7 PRO 7840U is faster than the Ryzen 9 6900HX. Despite this, the Ryzen 9 6900HX has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. According to our data, the Ryzen 9 6900HX and Ryzen 7 PRO 7840U have the same clock speed. Despite this, the Ryzen 7 PRO 7840U has a slightly higher turbo speed. In terms of cache, the Ryzen 7 PRO 7840U has significantly more L2 cache when compared to the Ryzen 9 6900HX. 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 Ryzen 9 6900HX has more threads than cores. Each physical core is split into multiple threads.
