The AMD Ryzen 5 2500U Accelerated Processing Unit (APU) has made its first appearance in a Geekbench benchmark posting some impressive scores. AMD has been claiming for quite sometime that the upcoming Ryzen Mobile APUs will have up to 50% more CPU performance and 40% more GPU performance for half the power consumed by the previous generation Bristol Ridge APUs. The Ryzen 5 2500U Geekbench scores seem to somewhat testify AMD's claims. The leaked scores show that compared to the Excavator-based A12-9800 'Bristol Ridge' APU, the Ryzen 5 2500U APU has a 36% higher single-core performance with a score of 3561 (compared to 2607 for the A12-9800) and a 48% higher multi-core performance with a score of 9421 (the A12-9800 posted 6329). Interestingly, the Ryzen 5 APU in this Geekbench test was supposedly clocked at 2 GHz (it could have very well turbo-ed during the test) while the A12-9800 was clocked at 3.8 GHz. These benchmarks are not the first ones to be leaked, though. Earlier, there were sightings of the Ryzen 5 2500U and the Ryzen 7 2700U APUs on GFXBench showing promising numbers.

The higher performance figures are a given considering the fact that the quad core Ryzen 5 features SMT, yielding a total of 8 threads and also due to the improvements brought forth by the Zen architecture. There are a lot of details missing, however. We do not yet know the specifics of the on-die components. The Vega GPU used on-die is somewhat of a mystery. It is not yet clear whether the on-die Vega uses the newer HBM2 memory as seen in the desktop Vega GPUs or dual-channel memory. There's also no clarity on the number of stream processors on the on-die Vega. Going by AMD's claims of 40% more GPU performance, one can speculate that the Vega could have as many as 1024 SPs (the GCN 1.2-based GPU in Bristol Ridge had 512 SPs). Then, there is also uncertainty as to whether the integrated chipset will be on-die or on-package.
