TechPowerUp took a look at the figures and calls it a major improvement versus the AMD A12-9800 "Bristol Ridge" APU. The Ryzen 5 2500U performs 36 percent better in single-performance Geekbench tests and 48 percent better in the multi-core tests than the A12-9800.
One interesting note here is that the Ryzen 5 2500U's clockspeed of 2.0GHz is significantly lower than the 3.8GHz clockspeed of the A12-9800, so this really shows the progress AMD has made with its Zen design. The real question is how this will perform in games, but unfortunately there are still no indications of what the Vega-based APUs are capable of.
As always, take these early scores with a grain of salt. We don't know the accuracy and they may not be representative of the full performance of the final retail pairts.
