- Const-me 3y agoI don’t think in this case it matters even for spiky workloads. The relative difference is too small. The difference in CPU base frequency is 3.8 versus 4.0 GHz, which is 5% slower. However, for spiky workloads boost frequency is IMO more relevant than base frequency. With boost, the clock speed difference diminishes to the laughable 2%. Specifically, they are 5.2GHz for the R9, and 5.1GHz for the R7. AMD doesn’t publish boost clock for GPU, but relative difference in base GPU frequency is 3.6%. I’m aware marketing generally works, making people willing to pay more just for the feeling they have the best hardware money can buy. But personally, I believe saving these $285 and getting 95-98% of the performance is a good deal. P.S. Ryzen 5 from the same line up, the 7640HS, is substantially slower. It has fewer CPU cores, and fewer GPU compute units.
