Architecture Differences

The two processors come from fundamentally different design families. The AMD Ryzen 5 PRO 8645HS uses Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. The Intel Core i7-14701E uses Raptor Lake architecture under the Raptor Lake-R codename, built on a 10 nm process at Intel's own foundry. The process node difference is substantial, with AMD at 4 nm and Intel at 10 nm, though both are active production parts.

Core and thread counts differ. The AMD part has 6 cores and 12 threads, while the Intel part has 8 cores and 16 threads. The Intel chip also has a higher boost clock of 5.40 GHz versus 5.00 GHz for the AMD chip, though the AMD part has a much higher base clock of 4.30 GHz versus 2.60 GHz. The Intel part carries a 65 W TDP rating, while the AMD part is rated at 45 W.

Cache configurations show different design philosophies. The AMD part uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part uses 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Intel chip therefore has more total cache at every level. Transistor counts are listed only for the AMD part at 25,000 million, with a die size of 178 mm². The Intel die is larger at 257 mm², but its transistor count is not recorded in the database.

Memory support differs. The AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. Both use dual-channel memory buses. The AMD part has a recorded memory bandwidth of 89.6 GB/s; the Intel memory bandwidth field is not recorded. Both support ECC memory. PCIe capabilities differ: the AMD chip provides Gen 4 with 20 CPU lanes, while the Intel chip provides Gen 5 with 16 CPU lanes.

Integrated graphics differ as well. The AMD part includes Radeon 760M graphics, while the Intel part includes UHD Graphics 770. The AMD part is a mobile segment processor on AMD Socket FP7, while the Intel part is a desktop segment processor on Intel Socket 1700. Neither processor has an unlocked multiplier. The AMD part has two part numbers listed, 100-000001315 (FP7r2) and 100-000001388 (FP7), while the Intel part lists one, Q49FSRNJK. Release dates place the AMD part at 2024-04-15 and the Intel part at 2024-06-30.

The Verdict

The benchmark data makes a straightforward case. The Intel Core i7-14701E delivers the higher average benchmark score at 33206, holds the higher percentile at 83, and wins the majority of head-to-head tests. Its multi-core Cinebench R23 lead of 11.1% and its PassMark physics lead of 49.6% are substantial. The Intel part also has more cores, more threads, more L3 cache, and a higher boost clock. For workloads that rely on multi-threaded compute, integer math, floating point math, or prime number finding, the recorded data favors Intel.

The AMD Ryzen 5 PRO 8645HS is the better option only in specific workloads. Its 17.0% lead in data encryption, 14.5% lead in extended instructions, and 21.7% lead in random string sorting are real advantages. The AMD part also has the lower TDP at 45 W versus 65 W, a higher base clock, and a smaller die at 178 mm² versus 257 mm². The 4 nm TSMC process gives it a manufacturing node advantage, and the mobile segment designation indicates it is built for a different physical environment than the desktop-class Intel part.

The database shows the Intel part winning 14 of 17 comparisons, with the AMD part winning 3. The average score gap of 2327 points between the two parts, 33206 versus 30879, is consistent with the head-to-head results. Users prioritizing encryption, extended instruction throughput, or random string sorting should consider the AMD part. Users prioritizing general compute, physics, floating point, or multi-threaded performance should select the Intel part, as the recorded measurements support that choice.
