New AMD Ryzen 7 7840U APU benchmarks demonstrate performance on par with top-tier desktop CPUs in a 15W design. The AMD Ryzen 7 7840U Phoenix APUs is one of the many Ryzen 7040U intended for the 15-28W laptop and handheld market.
In addition to the Radeon 780M iGPU, which makes use of the RDNA 3 GPU architecture, the AMD Ryzen 7 7840U has 8 cores and 16 threads based on the Zen 4 core architecture. It has 12 processing units, giving it a total of 768 cores that operate at a frequency close to 2800 MHz.
The AMD Ryzen Z1 is the same APU that is available for portable gaming consoles. The Ryzen Z1 Extreme, which made its public debut recently, uses this specific configuration. The Ryzen 7040U Pro and Standard APUs are intended for laptops and notebooks, while the ASUS ROG Ally handheld and several other portable gaming solutions will be powered by it.
This specific AMD Ryzen 7 7840U Pro entry was discovered in a Lenovo laptop that had 64 GB of LPDDR5X-7500 memory but no discrete GPU, which is fortunate given that the Radeon 780M benchmarks have shown it to be an extremely capable integrated GPU. AMD Ryzen 7 7840U Pro achieved performance scores of 24,29 in single-core tests and 11,268 in multi-core tests.
The AMD Ryzen 7 7840U outperforms every Ryzen APU from the Ryzen 6000 and Ryzen 5000 families from the previous generation.
Even the Ryzen 9 6900HX, which has a much higher power target, cannot compete and falls short in single-core and multi-core tests by a combined 25% and 20%. In single-core tests, the 15-28W APU is also quicker than desktop-class AMD & Intel chips, and it performs admirably in multi-core tests.
Although Ryzen 7000 and Intel 13th Gen CPUs are faster, they also use 100 to 200 W more power, or four times as much as this chip. It’s important to keep in mind that laptops may still perform slightly better than handheld consoles because they have more space for additional cooling than the compact handheld designs.
