AMD Ryzen 7 7840U Laptop CPU is up to 40% Faster than Ryzen 7 6800U at Half the Power [Report]

AMD’s Ryzen 7000 mobile processors will be the star of this generation. While the desktop chips fall short of their Raptor Lake rivals, Phoenix and Dragon Range decisively beat the competition. We’ve extensively covered the Ryzen 9 7945HX in the past few months. Not only does it beat the Core i9-13980HX by a substantial margin, but it’s also more power efficient.

The Ryzen 7 7840U is a 28W processor designed for ultrathins and convertibles. Featuring x8 Zen 4 cores and x16 threads, it will be the go-to APU for mainstream notebooks. A few benchmarks of this chip have been leaked, indicating stellar performance in a small power envelope.

According to a set of benchmarks from Weibo, the Ryzen 7 7840U is over 40% faster than its predecessor, the Ryzen 7 6800U. It also manages to beat the 35-45W R9 6900HX while drawing a fraction as much power. As per the leak, the R7 7840U draws nearly half as much power as its predecessor while offerings substantially more performance.

In addition to Cinebench R23, the R20 and 3DMark numbers are also included. In the former, the Ryzen 7 7840U scores around 700 points which is in the ballpark of desktop Zen 4 processors. The accompanying Radeon 780M iGPU scores 8,000 points in FireStrike which is roughly on par with the GeForce GTX 1650/1650 Ti dGPU.

AMD has delayed the launch of its Ryzen 7040U “Phoenix” processors to April to match the manufacturing readiness of its OEM partners. The Ryzen 7045HX “Dragon Range” chips are already out in high-end gaming notebooks.
