The Intel part has a higher boost clock, which may explain its wins in math-heavy workloads, but its much lower base clock is a disadvantage in sustained workloads.

The AMD part has a TDP of 65 watts, while the Intel part has a TDP of 45 watts. The Intel part is designed for mobile systems with lower thermal limits.

Specification Differences

The core and thread counts are the most obvious specification difference. The AMD Ryzen 3 4100 has 4 cores and 8 threads, while the Intel Core i7-8750H has 6 cores and 12 threads. Despite having 50% more cores and 50% more threads, the Intel part loses most multi-threaded benchmarks, which highlights the per-core efficiency advantage of the Zen 2 architecture.

Clock speeds differ significantly. The AMD part has a base clock of 3.80 GHz and a boost clock of 4.00 GHz. The Intel part has a base clock of 2.20 GHz and a boost clock of 4.10 GHz. The Intel boost clock is 0.10 GHz higher, but its base clock is 1.60 GHz lower.

Memory support is DDR4 for both, but the AMD part has a recorded dual-channel memory bus and 51.2 GB/s of memory bandwidth, while the Intel part has no recorded memory bus or bandwidth specification. Neither part supports ECC memory.

The AMD part has no integrated graphics, while the Intel part includes UHD 630 integrated graphics. This is a notable difference for users who need a display output without a discrete GPU.
