Where Each One Wins

The AMD Ryzen AI 5 340 is the stronger choice for heavily threaded workloads. Its 12 threads and dual-channel memory give it a commanding lead in integer math, data compression, random string sorting, and extended instruction tests. The 95.3% lead in integer math and the 56.5% lead in data compression indicate that productivity tasks such as database operations, compression utilities, and general computation will run noticeably faster. The Cinebench R15 multicore result (44.9% ahead) reinforces this pattern, as does the PassMark multithread score (26.3% ahead). The AMD chip also edges ahead in Cinebench R23 singlecore and data encryption, showing it can handle single-threaded responsiveness without sacrificing multi-thread muscle.

The Intel Core 3 305 wins where single-thread efficiency and specific mathematical operations matter. Its PassMark single thread score is 7.4% higher, which suggests faster response in lightly threaded applications. The find prime numbers result shows a 37.4% advantage, a strong indicator for workloads involving primality testing or similar integer-heavy single-thread algorithms. Floating point math goes to Intel by 5.5%, and PassMark physics by 11.2%. The Cinebench R23 multicore win (4.5% ahead) is notable because it contradicts the broader multi-thread trend, possibly reflecting the Intel chip's higher sustained single-core performance in that specific renderer. The lower 15 W TDP also makes the Intel chip more suited to power-constrained chassis.

The Verdict

The recorded data points to the AMD Ryzen AI 5 340 as the faster overall processor for most compute tasks. It wins two-thirds of the head-to-head comparisons, including the largest margins in integer math and data compression. Its 12 threads, dual-channel memory, and 89.6 GB/s bandwidth provide a structural advantage for parallel workloads. The 78th percentile ranking versus 72nd for Intel reinforces this: the AMD chip sits higher in the global performance distribution.

The Intel Core 3 305 is the better pick for workloads that favor single-thread speed and low power draw. Its 15 W TDP is nearly half the AMD chip's 28 W rating. The PassMark single thread lead and the find prime numbers advantage make it suitable for specific single-threaded algorithms. The 3 nm process node also gives it a manufacturing advantage, though the AMD chip's 4 nm node remains competitive. The Intel chip's launch MSRP of $309 provides a reference point, but the data does not include a comparable price for the AMD part.

For a mobile system where battery life and light-thread responsiveness are top priorities, the Intel Core 3 305 delivers. For a mobile workstation or a device handling compression, encryption, and multi-threaded rendering, the AMD Ryzen AI 5 340 is the stronger option based on the recorded benchmark scores.
