Architecture Differences

The AMD Ryzen 7 PRO 8840U uses the Zen 4 architecture under the Hawk Point codename, fabricated on a 4 nm process at TSMC. The Intel Core i7-14701TE uses Raptor Lake architecture under the Raptor Lake-R codename, fabricated on a 10 nm process at Intel. The transistor counts reflect this: AMD lists 25,000 million transistors on a 178 mm² die, while Intel does not disclose a transistor count but has a 257 mm² die.

Cache hierarchies diverge significantly. The AMD part provides 64 KB of L1 cache per core and 1 MB of L2 per core, with 16 MB of shared L3. The Intel part provides 80 KB of L1 per core and 2 MB of L2 per core, with 33 MB of shared L3. This gives Intel more than double the L3 capacity, which may help in certain workloads that benefit from larger shared pools.

Memory support differs: the AMD Ryzen 7 PRO 8840U supports DDR5 only with dual-channel memory and a recorded bandwidth of 89.6 GB/s. The Intel Core i7-14701TE supports both DDR4 and DDR5 with dual-channel memory, though no memory bandwidth figure is recorded for it. Both support ECC memory.

PCIe connectivity also differs. The AMD chip provides Gen 4 with 20 lanes from the CPU, while the Intel chip provides Gen 5 with 16 lanes. This gives Intel a newer PCIe generation but fewer total lanes.

The integrated graphics differ: AMD uses Radeon 780M, while Intel uses UHD Graphics 770. Market segments also differ, with the AMD part classified as Mobile (using AMD Socket FP7) and the Intel part classified as Desktop (using Intel Socket 1700). Production status is Active for both.

Where Each One Wins

The AMD Ryzen 7 PRO 8840U wins 15 of the 17 head-to-head benchmark comparisons. Its victories span both Cinebench and PassMark suites, covering multi-core, single-core, encryption, compression, integer math, floating-point math, and random string sorting. The largest win comes in PassMark random string sorting, where AMD leads by 45.5%. PassMark data encryption shows a 40.5% advantage, and PassMark single-thread shows a 38.1% advantage.

The Intel Core i7-14701TE wins only two tests: PassMark find prime numbers and PassMark physics. The prime number test shows Intel ahead by 46.9%, the largest margin in either direction across all tests. The physics test shows Intel ahead by 36.9%. These are specialized workloads that appear to favor Intel's architecture despite the AMD chip winning most other measures.

The pattern suggests a split: AMD dominates general-purpose computing, content creation, and memory-bandwidth-sensitive tasks, while Intel holds specific advantages in prime number computation and physics simulation. The AMD chip's higher base clock of 3.30 GHz versus 2.10 GHz likely contributes to its broad lead, while Intel's larger L3 cache and different microarchitecture may explain its niche wins.

Specification Differences

The AMD Ryzen 7 PRO 8840U has a base clock of 3.30 GHz and a boost clock of 5.10 GHz, while the Intel Core i7-14701TE has a base clock of 2.10 GHz and a boost clock of 5.20 GHz.
