The AMD Ryzen 5 6600U is the latest Zen 3+ “Rembrandt” mobile processor to make its way onto the PassMark test site, with a single sample displaying good enough results to keep up with the more-powerful Intel Core i7-1260P. Along with beefed-up TDP and clock rates, the Ryzen 5 6600U can also brag of having an RDNA2-powered iGPU.

The Ryzen 5 6600U APU has finally joined some of the other Zen 3+ Rembrandt chips on PassMark. The mobile processor, which is headed for thin and light laptops and handheld consoles, managed a single-thread score of 3,201 while clocking up a CPU Mark score of 17,257. Not only did these results deliver slightly better than expected improvements over the Ryzen 5 5600U, but they also helped the AMD Ryzen 5 6600U keep up with Intel Alder Lake rivals such as the Core i5-1240P and Core i7-1260P.

As the world holds its breath for the arrival of Zen 4 Ryzen 7000 “Raphael” parts (and Intel’s competing Raptor Lake series), the Zen 3+ mobile APUs could easily be overlooked, especially as they seem to have taken forever to travel from announcement date to actual appearances in devices. However, synthetic benchmark results have been strong, and Rembrandt parts get to boast of having RDNA2-based iGPUs, with the Ryzen 5 6600U being associated with the entry-level Radeon 660M, which can still muster a satisfactory graphics performance.

The single Ryzen 5 6600U sample here, which is listed with a high margin for error, speeds away from the Ryzen 5 5600U predecessor by +9.59% (single) and +11.73% (multi), showing decent gains over the space of a single year (Zen 3: January 2021; Zen 3+: January 2022). The AMD Ryzen 6600U can thank its TDP and clock-rate buffs for the improvements, with the 15-28 W TDP (typical 25 W) and 2.9-4.5 GHz clock rates demonstrating tasty upgrades from 10-25 W TDP (typical 15 W) and 2.3-4.2 GHz for the Ryzen 5 5600U.

The efficient Ryzen 5 6600U also holds up well against the Intel Core i5-1240P and Intel Core i7-1260P, which are decent processors in their own right but somewhat power-hungry in comparison. The chips from Team Blue have core-count advantages at 12 (4P + 8E) vs. 6 cores and a large power consumption range of 28 W (PL1) to 64 W (PL2). Learning that the i5-1240P is only +3.37% (single) and +3.11% (multi) ahead of the Zen 3+ part while the i7-1260P is +2.16% (single) ahead and actually -0.27% (multi) down, despite additional cores and higher power consumption, really shines a bright light on the AMD Ryzen 5 6600U on this particular synthetic benchmark.
