HP 15-bw075ax (A12-9720P, Radeon R7) Laptop Review
AMD A12-9720P | AMD Radeon R7 (Bristol Ridge) | 15.60" | 1.9 kg
The AMD A12-9720P is a mainstream SoC from the Bristol Ridge APU series for notebooks (7th APU generation), which was introduced in 2017. The ULV chip with a TDP of 15 Watts (can be configured to 12 Watts, not verified) has four CPU cores (two Excavator modules) clocked at 2.7 - 3.8 GHz (4.05 GHz for single core were briefly achievable in our test sample), a Radeon R7 iGPU as well as a dual-channel DDR4-1866 memory controller. Carrizo is a full-fledged SoC and is also equipped with an integrated chipset, which provides all I/0 ports.
Architecture
Bristol Ridge is the successor of the Carrizo architecture and the design is almost identical. Thanks to optimized manufacturing processes and more aggressive Boost behavior, however, the clocks are a bit higher at the same power consumption. The memory controller now also supports DDR4-RAM, in this case up to 1866 MHz. More technical details are available in the following articles:
Performance
The average A12-9720P in our database is in the same league as the Core i5-4210U, as far as multi-thread benchmark scores are concerned, making the former a fairly slow chip that's suitable for basic day-to-day activities only as of late 2022.
Graphics
The integrated Radeon R7 (Bristol Ridge) GPU has 512 active shader units (8 compute cores) clocked at up to 758 MHz. Thanks to the better utilization of the clock range as well as faster DDR4-RAM, the GPU can slightly beat its predecessors Radeon R7 (Carrizo) and competes with a dedicated GeForce 920MX in the best-case scenario (dual-channel memory, low CPU requirements). Many games from 2015/2016 can be played smoothly at low settings.
Power Consumption
AMD specifies the TDP of the A12-9720P with 15 Watts, which is comparable to Intel's ULV models. This means the CPU is a good choice for thin notebooks starting with a 12-inch screen.
