AMD Ryzen 5 7645HX vs Intel Core i7-14701E Comparison

The AMD Ryzen 5 7645HX and Intel Core i7-14701E occupy adjacent tiers in the benchmark database, with the AMD part landing at the 84th percentile and the Intel part at the 83rd percentile of all CPUs. Their average benchmark scores sit close together — 33,668 for the AMD versus 33,206 for the Intel — yet the data reveals two very different performance profiles. The Ryzen 5 7645HX is a mobile 6-core Zen 4 chip built for efficiency, while the Core i7-14701E is a desktop 8-core Raptor Lake Refresh processor. Across 15 head-to-head benchmark comparisons, the Intel part wins 8 and the AMD part wins 7, but the margin and nature of those wins tell the real story: Intel dominates heavily in rendering and single-threaded tests, while AMD counters with decisive leads in encryption, compression, and sorting workloads.

The Verdict

The data points to a clear split by workload type rather than an overall winner. For users running long multi-threaded renders or physics simulations, the Intel Core i7-14701E is the stronger pick. Its Cinebench R23 multi-core lead of 37% (22,195 vs 13,985) and PassMark physics lead of 37.6% (2,399 vs 1,497) are substantial, and its 4.8% edge in PassMark integer math (81,325 vs 77,432) reinforces a general compute advantage. The Intel part also wins the single-core comparison outright, with a 42.3% lead in Cinebench R23 single-core and a 9.2% lead in PassMark single-thread, making it the better choice for lightly threaded applications and responsive daily use.

However, the AMD Ryzen 5 7645HX is the better pick for data-oriented workloads that stress encryption, compression, and sorting. It wins PassMark data encryption by 20.4% (17,900 vs 14,862), PassMark extended instructions by 24% (22,969 vs 18,528), and PassMark random string sorting by 18.1% (34,434 vs 29,158). It also edges out the Intel part in PassMark multi-thread by 1.4% (26,476 vs 26,112) and Cinebench R15 multi-core by 1.7% (2,276 vs 2,237), showing that its 6-core design can keep pace in certain mixed workloads despite the core count disadvantage. Given the Intel part’s 65W TDP and desktop Socket 1700 platform versus the AMD’s 45W TDP and mobile Socket FL1, the AMD is the obvious choice for power-constrained or portable systems, while the Intel fits desktop builds where higher power draw is acceptable.

Head-to-Head Benchmarks

The biggest win for the Intel Core i7-14701E comes in Cinebench R23 multi-core, where it scores 22,195 against the AMD’s 13,985 — a 37% advantage. This is the single largest delta in either direction across all 15 comparisons. The Intel part also wins Cinebench R23 single-core by 42.3% (3,133 vs 1,809), the largest single-core gap. PassMark physics follows a similar pattern: Intel leads by 37.6% with 2,399 versus 1,497. In PassMark floating point math, the Intel chip scores 61,873 versus 48,798, a 21.1% lead. The Intel part also takes PassMark single-thread by 9.2% (4,305 vs 3,907) and PassMark integer math by 4.8% (81,325 vs 77,432). In Cinebench R15 single-core, Intel wins by 8.3% (315 vs 289).

The AMD Ryzen 5 7645HX counters with its own set of decisive victories. PassMark extended instructions is the AMD’s biggest win: 22,969 versus 18,528, a 24% margin. PassMark data encryption follows at 20.4% (17,900 vs 14,862). PassMark random string sorting goes to AMD by 18.1% (34,434 vs 29,158). PassMark data compression is a 6.8% win for AMD (302,256 vs 282,939). The AMD part also wins Cinebench R15 multi-core by 1.7% (2,276 vs 2,237), PassMark multi-thread by 1.4% (26,476 vs 26,112), and PassMark find prime numbers by 1.1% (178 vs 176). These narrower wins in multi-thread and compression tests suggest the AMD’s Zen 4 architecture handles certain parallel tasks more efficiently despite having fewer cores.

Specification Differences

The Intel Core i7-14701E and AMD Ryzen 5 7645HX differ in nearly every core specification. The Intel part has 8 cores and 16 threads, while the AMD has 6 cores and 12 threads. Base clocks diverge sharply: the AMD runs at 4.00 GHz, while the Intel runs at 2.60 GHz — but the Intel boosts higher at 5.40 GHz versus the AMD’s 5.00 GHz. Thermal design power also differs, with the Intel rated at 65W and the AMD at 45W. The processors use different sockets: the AMD uses AMD Socket FL1, while the Intel uses Intel Socket 1700. The AMD is a mobile-market chip, while the Intel is a desktop-market chip. Memory support differs as well: the AMD supports only DDR5, while the Intel supports both DDR4 and DDR5. Both use dual-channel memory buses, but the AMD lists a memory bandwidth of 83.2 GB/s while the Intel does not list a bandwidth figure. The AMD provides 28 PCIe Gen 5 lanes, while the Intel provides 16 PCIe Gen 5 lanes. Integrated graphics differ: the AMD has Radeon 610M, while the Intel has UHD Graphics 770. The cache configuration also differs, with the AMD offering 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3, versus the Intel’s 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3.

Architecture Differences

The architectural split between these two parts is fundamental. The AMD Ryzen 5 7645HX is built on TSMC’s 5 nm process with Zen 4 architecture and the Dragon Range codename, part of the 7000 series. It contains 6,570 million transistors on a 71 mm² die. The Intel Core i7-14701E uses Raptor Lake Refresh architecture under the Raptor Lake-R codename, fabricated on Intel’s 10 nm process, with a die size of 257 mm² and no transistor count listed. The AMD is a 6-core, 12-thread design with a single-CCX layout and 32 MB of shared L3 cache. The Intel is an 8-core, 16-thread design with 33 MB of shared L3 cache and a larger per-core L2 allocation. The AMD’s Zen 4 cores are engineered for a mobile platform with a 45W TDP, while the Intel’s Raptor Lake cores target a desktop platform at 65W. The AMD’s 5 nm process and 71 mm² die contrast sharply with the Intel’s 10 nm process and 257 mm² die, which partly explains the AMD’s efficiency advantage in power-constrained scenarios. The AMD also supports only DDR5 memory and offers 28 PCIe Gen 5 lanes, whereas the Intel supports legacy DDR4 alongside DDR5 and provides 16 PCIe Gen 5 lanes. The integrated graphics differ by vendor and model — Radeon 610M for AMD versus UHD Graphics 770 for Intel — and the release dates are about 18 months apart, with the AMD launching in January 2023 and the Intel in June 2024. Both are currently active production parts with locked multipliers.
