AMD Ryzen 7 7745HX vs Intel Core i7-14701E Comparison

The Intel Core i7-14701E and AMD Ryzen 7 7745HX are both 8-core, 16-thread processors that land in the same performance neighborhood, yet they achieve it through fundamentally different designs. The data shows a near-perfect split: the Intel part wins 7 head-to-head benchmarks, while the AMD part wins 8. The average benchmark scores are nearly identical, with the Intel at 33206 and the AMD at 33091, a delta of just 0.3%. However, the nature of their wins could not be more different, making the choice between them a matter of workload rather than raw capability.

Where Each One Wins

The AMD Ryzen 7 7745HX dominates in throughput-oriented tasks that stress memory bandwidth and parallel execution. Its largest victories come in data compression, where it scores 383322 against Intel’s 282939, a 26.2% advantage. Data encryption shows a similar story, with AMD at 22967 versus Intel’s 14862, a 35.3% lead. Extended instruction workloads favor AMD heavily, with a 36% delta (28966 vs 18528). Integer math also goes to AMD, 105773 versus 81325, a 23.1% margin. Random string sorting is another AMD stronghold, 44474 vs 29158, a 34.4% gap. The AMD chip also wins the PassMark multithread test, scoring 32581 against 26112, a 19.9% lead, and edges out floating-point math at 64297 vs 61873, though by a slimmer 3.8%.

The Intel Core i7-14701E, meanwhile, owns the single-threaded and latency-sensitive categories. It wins Cinebench R23 single-core by a massive 69.4% (3133 vs 1850), and Cinebench R15 single-core by 7% (315 vs 294.5). PassMark single-thread also goes to Intel, 4305 vs 3947, a 9.1% margin. In physics calculations, Intel is dominant, scoring 2399 against AMD’s 1697, a 41.4% lead. Intel also takes prime number finding, 176 vs 156, a 12.8% win. In Cinebench R23 multi-core, Intel reverses the multithread trend, scoring 22195 against AMD’s 18452.5, a 20.3% victory, though AMD wins Cinebench R15 multi-core by 25.1% (2986 vs 2237).

Architecture Differences

These are two very different silicon designs. The Intel Core i7-14701E is built on Intel’s 10 nm process, with a die size of 257 mm², and comes from the Raptor Lake refresh generation. It uses the Intel Socket 1700 platform and is a desktop part. The AMD Ryzen 7 7745HX is built on TSMC’s 5 nm node, with a dramatically smaller die of 71 mm² and a transistor count of 6,570 million. It uses the AMD Socket FL1 and is a mobile part from the Dragon Range family, based on Zen 4 architecture.

Cache structures differ notably. Intel allocates 80 KB of L1 per core and 2 MB of L2 per core, with a shared 33 MB L3 cache. AMD uses 64 KB L1 per core and 1 MB L2 per core, with a shared 32 MB L3. The Intel part has a higher boost clock at 5.40 GHz versus AMD’s 5.10 GHz, but the AMD chip has a higher base clock at 3.60 GHz versus Intel’s 2.60 GHz. The AMD processor supports a higher memory bandwidth of 83.2 GB/s, while Intel’s memory bandwidth is not specified. Both support ECC memory and dual-channel memory, but Intel supports both DDR4 and DDR5, whereas AMD supports only DDR5. Intel’s integrated graphics is UHD Graphics 770, while AMD’s is Radeon 610M. Both have PCIe Gen 5, but AMD offers 28 lanes versus Intel’s 16. The AMD chip has an unlocked multiplier, while Intel’s is locked. Intel’s TDP is 65 watts, AMD’s is 55 watts, though the AMD part is rated for mobile.

Head-to-Head Benchmarks

The single largest margin in the entire comparison belongs to Intel in Cinebench R23 single-core. The 69.4% delta (3133 vs 1850) is staggering and suggests the Intel architecture has a massive per-thread advantage. This is reinforced by the 41.4% win in PassMark physics and the 9.1% single-thread win. For users running lightly threaded applications like older games or certain productivity tools, the Intel part is clearly superior.

AMD’s biggest wins are in data compression (26.2%), encryption (35.3%), and extended instructions (36%). These are workloads that benefit from the Zen 4 design’s memory bandwidth and instruction-level parallelism. The 19.9% win in PassMark multithread (32581 vs 26112) shows AMD’s overall throughput is higher in most parallel workloads, but the Cinebench R23 multi-core result flips that narrative. Intel wins that test by 20.3% (22195 vs 18452.5), which indicates that Cinebench’s rendering workload responds better to Intel’s cache layout and clock speed than to AMD’s raw bandwidth. The two processors also split the older Cinebench R15 multi-core test, with AMD winning 2986 vs 2237.

The PassMark data compression result (383322 vs 282939) shows AMD’s advantage is not marginal; it is a 35%+ performance gap in some integer-heavy tasks. Conversely, Intel’s Cinebench R23 single-core dominance is even larger, at 69.4%. The pattern is clear: if the workload is highly parallel and memory-bandwidth-bound, AMD wins decisively. If it is latency-bound or lightly threaded, Intel wins by an even larger margin.

The Verdict

The data does not point to a single winner; it points to two distinct use cases. Choose the Intel Core i7-14701E if your priority is single-threaded performance, physics simulation, or lightly threaded applications. The 69.4% lead in Cinebench R23 single-core and 41.4% lead in PassMark physics are decisive. It is also a desktop part with a 65 W TDP, which suggests it is designed for sustained desktop workloads, and its support for DDR4 offers platform flexibility.

Choose the AMD Ryzen 7 7745HX if your workloads are heavily parallel, involve data compression, encryption, or extended instruction sets. The 35.3% lead in encryption and 36% lead in extended instructions are impossible to ignore for security or scientific computing. Its higher memory bandwidth (83.2 GB/s) and lower TDP (55 W) make it a compelling mobile option, and the unlocked multiplier offers tuning headroom.

The average benchmark scores (33206 for Intel, 33091 for AMD) and percentile rankings (83 for both) place these chips in the same tier. The real question is whether your software scales with bandwidth or with clock speed. AMD wins 8 benchmarks, Intel wins 7, but the margins on each side are large enough that a wrong choice could cost you 20-30% performance in your specific application. Match the chip to the workload, not the other way around.
