AMD's Phoenix U-Series laptop CPUs within the Ryzen 7040 family are slowly starting to make an appearance as the Ryzen 7 7840U has now leaked.

Recently, we talked about the AMD Ryzen 5 7640U Phoenix CPU which appeared on Geekbench. This was one of the first official Ryzen 7000 CPUs that AMD themselves confirmed for laptops. As expected, there are more, and now, we have our first look at the Ryzen 7 7840U.
The AMD Ryzen 7 7840U is another Ryzen 7040U Phoenix APU which is designed for the 15-28W laptop designs. This CPU carries 8 cores and 16 threads based on the Zen 4 core architecture and also packs a Radeon 780M iGPU that utilizes the RDNA 3 graphics architecture. In Cinebench R23, the CPU is shown to offer a 3.3 GHz base clock which is 500 MHz lower than the base clock of the Ryzen 7 7840HS but that chip is double the TDP going all the way up to 54W. We can't say for sure whether this is the final base clock and we also don't get any boost clock numbers for the CPU or the GPU.
What we do get is the Cinebench R23 Multi-Threaded performance result for the AMD Ryzen 7 7840U CPU and those look very decent. The chip scores 14,771 points which put it ahead of the Ryzen 9 6980HX which is a 45W design. The CPU is also over 40% faster in multi-threading than Ryzen 7 6800U, another 8 core and 16 thread SKU based on the Zen 3+ architecture.
This Lenovo laptop is also said to offer half the power consumption with higher single-core and multi-core performance than the previous generation. Graphics performance is also said to be doubled while retaining great battery timing.

Other benchmark results pointed are around 700 points in the Cinebench R20 (Single-Core) test, around 3000 graphics score in 3DMark Time Spy which is what we have seen for the Radeon 780M earlier too, and FireStrike score of 8000 points in the graphics test.

The AMD Ryzen 7040U Phoenix Laptop CPUs including the Ryzen 7 7840U and Ryzen 5 7640U are expected to arrive in the coming quarter within thin and light notebooks. We can expect higher and better performance results in the final products compared to what we are seeing currently.
