AMD Ryzen 5 5500U (Lucienne) Bench Leaks Out: Up to 20% Faster than the 4500U (Renoir)

The Geekbench score of AMD’s upcoming Ryzen 5 5500U mobile processor has leaked out, showing a total improvement of 20% over the existing 4500U at the same frequency.

4500U

Unlike the Ryzen 4000 lineup, the Ryzen 5000 APUs will be based on both the Lucienne (Zen 2 refresh) and Cezanne (Zen 3) designs. As such, you can expect considerable differences in the performance of adjacent models.

In the above picture, you have the performance figures of the Ryzen 5 5500U which is a Lucienne part, featuring the same Zen 2 cores and 7nm Vega iGPU as the Renoir parts. While the single-threaded performance is the same as the 4500U, the multi-threaded score is roughly 20% higher despite having the same operating frequency. We’re guessing that this is the result of better boost residency which is also one of the core features of the Ryzen 3000XT (Matisse 2) CPUs.

This 20% seems to be coming from enabling SMT on (almost didn’t notice). While the 4500U is limited to 6 cores and 6 threads, the 5500U comes with 12 threads, a result of simultaneous multi-threading (SMT) being enabled. Rather disappointing, no?

AMD is expected to announce the Ryzen 5000 mobile processors at CES 2021 in January, with a launch date of March-April. That’s roughly when Intel will launch its Tiger Lake-H CPUs (8C/16T) as well, so it makes sense.
