Leaked benchmarks of AMD's upcoming laptop processors have been all over the place. While the Dragon Range-based Ryzen 9 7845HX rocketed to the top of PassMark's charts, the Phoenix-based Ryzen 9 7940HS failed to keep up with a last-gen Alder Lake flagship. Another Phoenix chip Ryzen 7 7840HS, has now been benchmarked. The processor will likely debut alongside the Alienware x16 sometime in Q2, 2022.
A Chiphell user posted what appears to be the Ryzen 7 7840HS on Cinebench R23, where it scored 16,854 points on the multi-core test. While its single-core result has been (badly) obfuscated, the single-to-multi-core ratio (10.61) gives it away (1,588). The poster justifies it by stating the chip is underperforming and that its actual score should be around 1,800. One can attribute this to the chip being a pre-production sample.
The Ryzen 7 7840HS offers significant performance gains over the Rembrandt-based Ryzen 7 6800H (1,524 S/T, 13,379 M/T) and Ryzen 9 6900H (1,568 S/T, 14,102 M/T). It even trades blows with the Core i9-12900H (1,8876 S/T, 16,575), although Intel will probably take back the lead with its 13th-gen Raptor Lake offerings. Then again, Cinebench R23 is just one benchmark, and it is best to reserve judgment until more show up.
Last-gen Ryzen 6000 laptops were quite hard to find, and one can only hope that AMD improves availability this time. The Ryzen 7 7840HS and its ilk pack a fairly potent Radeon 780M iGPU and would make for excellent gaming machines for those on a budget. Unfortunately, its high power draw makes it unsuitable for handhelds, which will likely have to make do with Rembrandt-R chips.
