AMD Ryzen 7 155
The AMD Ryzen 7 155 is a mid-range laptop processor from the Hawk Point Refresh series with six cores and simultaneous multithreading (SMT), allowing it to process up to twelve threads simultaneously. The CPU is based on the Zen 4 architecture and runs at a base clock speed of 3 GHz, with a single-core boost of up to 4.7 GHz. It offers 6 MB of L2 cache and 16 MB of L3 cache. Technically, the R7 155 is similar to the older Ryzen 5 8640U, but it has lower CPU clock speeds and a weaker iGPU.
Its performance is likely to be slightly below that of the older Ryzen 5 8640U and thus place it in the lower mid-range of current laptop processors.
The chip integrates an RDNA 3-based graphics unit (iGPU) called the Radeon 740M, with 4 CUs, a clock speed of up to 2.6 GHz, and an AV1 video engine. The XDNA AI accelerator, based on a Xilinx FPGA, is disabled on the Ryzen 7 155. In terms of interfaces, Hawk Point offers two USB 4 ports (40 Gbit/s), 14 PCIe 4.0 lanes, and a dual-channel memory controller for DDR5-4800 or LPDDR5x-7500 with ECC support.
The TDP of the Ryzen 7 155 is configurable between 15 and 40 watts, with 35 watts specified as the "default TDP."
