The AMD Ryzen 5 40 is a 4-core, 8-thread mobile processor with a 15-watt TDP, designed for low-power systems. Its nearest rivals in the database are server-class EPYC processors and a Core Ultra 5 mobile chip, with score differences under 0.5%. The Intel Core Ultra 7 270K Plus is a 24-core, 24-thread desktop processor with a 125-watt TDP, and its nearest rivals are Xeon and EPYC server parts, with the closest being the Intel Xeon 6520P at a 0% delta.

For users prioritizing maximum compute performance, the Intel processor is the clear choice based on the recorded results. For users prioritizing low power consumption and mobile form factors, the AMD processor is the only option that fits those constraints. The data does not show any workload category where the AMD processor comes out ahead.

Where Each One Wins

The Intel Core Ultra 7 270K Plus wins in every benchmark category recorded. Its largest advantages are in prime number finding, floating point math, and extended instructions, where it leads by more than 89% in each case. It also shows dominant leads in multithreaded workloads such as Cinebench R23 multicore and PassMark multithread, with deltas of -89.1% and -86.4% respectively.

The AMD Ryzen 5 40 does not win any benchmark category. Its closest relative performance comes in single-threaded tests, where the gap narrows to roughly -51% in PassMark single thread and Cinebench R23 singlecore. Even in these cases, the Intel processor delivers more than double the score.

The use cases split along form factor and power lines, not performance lines. The AMD Ryzen 5 40 is a mobile processor on a 15-watt TDP with integrated Radeon 610M graphics, suited to compact systems. The Intel Core Ultra 7 270K Plus is a desktop processor on a 125-watt TDP with unlocked multiplier and integrated Arc Xe-LPG Graphics 64EU, suited to high-performance desktop builds. The 24-core Intel processor also offers ECC memory support and PCIe Gen 5 connectivity, features absent from the AMD part.
