Starting with 3DMark Time Spy, for the CPU score we can see the i5-12400F in the Magnus Spark scores almost 1000 points higher than its direct predecessor, the i5-11400F, as used in the PCSpecialist Fusion Spark. Understandably it lags behind the i5-12600K as that CPU offers an extra 4 Efficient cores, as well as higher clock speeds.
In Cinebench R23, a similar pattern can be observed – the extra performance on offer from six Alder Lake cores versus six Rocket Lake cores is noticeable, both in the single-core and multi-core tests.
Time Spy's GPU score is also just what'd we would expect here – the RX 6600 is only fractionally faster than the RX 5600 XT in this benchmark, while it scores about 8% lower than an RTX 3060.
