The AMD processor has a die size of 178 mm² and contains 25,000 million transistors, while the Intel processor has a larger die size of 257 mm², with transistor count not recorded in the database.

Core configurations are notably different. The AMD Ryzen 5 PRO 8640HS provides 6 cores and 12 threads, while the Intel Core i7-14701E offers 8 cores and 16 threads. Cache hierarchies also differ: the AMD chip has 64 KB of L1 cache per core and 1 MB of L2 cache per core, whereas the Intel chip has 80 KB of L1 cache per core and 2 MB of L2 cache per core. The L3 cache is 16 MB shared on the AMD part versus 33 MB shared on the Intel part.

Memory support varies as well. The AMD processor supports DDR5 memory with a dual-channel bus and records a memory bandwidth of 89.6 GB/s. The Intel processor supports both DDR4 and DDR5 memory with a dual-channel bus, though its memory bandwidth is not listed in the database. PCIe connectivity differs, with the AMD chip using Gen 4 with 20 lanes (CPU only) and the Intel chip using Gen 5 with 16 lanes (CPU only). Integrated graphics also differ, with the AMD part featuring Radeon 760M and the Intel part featuring UHD Graphics 770.

Where Each One Wins

The Intel Core i7-14701E dominates across nearly all recorded workload categories. In multi-threaded scenarios, it leads by 18.4% in Cinebench R23 multi-core and by 17.8% in PassMark multithread. Single-thread performance also favors Intel, with an 18.4% advantage in Cinebench R23 single-core and a 17.3% edge in PassMark single-thread. The largest margins for Intel appear in specialized math workloads: PassMark find prime numbers shows a 59.7% advantage, and PassMark physics shows a 56.5% advantage. Floating-point math also heavily favors Intel, with a 30.5% lead.

The AMD Ryzen 5 PRO 8640HS wins in two specific areas. Data encryption shows a marginal 0.7% advantage for AMD, with scores of 14962 versus 14862. Random string sorting shows a more meaningful 3.7% edge for AMD, with scores of 30235 versus 29158. These wins suggest the AMD architecture holds a slight efficiency advantage in certain memory-intensive or cryptographic workloads, though the overall trend remains strongly in favor of Intel.

For users prioritizing raw compute throughput, the Intel processor is the clear choice based on the recorded data. The AMD part, however, remains competitive in specific niches. Given its mobile market segment and lower thermal design power of 28 watts versus 65 watts for Intel, the AMD Ryzen 5 PRO 8640HS appears suited for portable systems where the Intel desktop part would not be applicable.
