AMD Ryzen 7 8840HS vs Intel Core i7-14701E Comparison

Head-to-Head Benchmarks

The benchmark data splits these two 8-core/16-thread processors into two distinct personalities. The Intel Core i7-14701E dominates the Cinebench suite outright, while the AMD Ryzen 7 8840HS counters with strong showings in several specialized PassMark workloads. The overall win tally favors Intel at 10 of 15 head-to-head tests, but the nature of those wins matters more than the count.

Starting with the most dramatic gap: Cinebench R23 multi-core. The Intel Core i7-14701E scores 22195 against the AMD Ryzen 7 8840HS’s 13082, a 41.1% advantage. That is not a marginal lead; it is a class-level difference for heavily threaded rendering workloads. The single-core Cinebench R23 result is equally lopsided, with Intel at 3133 versus AMD’s 1737, a 44.6% delta. Cinebench R15 repeats the pattern: Intel wins multi-core 2237 to 2045 (8.6% ahead) and single-core 315 to 270 (14.3% ahead). If your workflow is built around Cinebench-style all-core or lightly threaded rendering, the Intel part is the clear choice from this data.

The PassMark suite tells a more nuanced story. The AMD Ryzen 7 8840HS wins five tests, and several of those wins are substantial. Data encryption is its best showing: 17650 versus 14862, an 18.8% lead. Random string sorting goes AMD’s way by 21.8% (35517 vs 29158). Extended instructions favor AMD by 11.8% (20714 vs 18528), and integer math sees AMD ahead by 11.1% (90382 vs 81325). Data compression is a narrower AMD win at 3.5% (292888 vs 282939). These are not trivial workloads — encryption and compression are common in file archiving, database operations, and security applications.

However, the Intel Core i7-14701E answers in PassMark’s remaining tests with decisive margins. Physics testing is a 52.1% Intel blowout (2399 vs 1149). Find prime numbers is similarly one-sided at 55.1% in Intel’s favor (176 vs 79). Floating point math goes Intel’s way by 15% (61873 vs 52582). The overall PassMark multithread score slightly favors Intel at 26112 versus 24990 (4.3% ahead), and the single-thread score shows Intel ahead by 15.8% (4305 vs 3626). The averaged benchmark scores back this up: the AMD Ryzen 7 8840HS sits at 33667 average versus Intel’s 33206, but both land in the same percentile neighborhood — 84th for AMD and 83rd for Intel against all CPUs.

The Verdict

The data supports a straightforward split. The Intel Core i7-14701E is the stronger processor for raw compute throughput, particularly in rendering, physics simulation, prime number calculations, and single-threaded tasks. Its Cinebench R23 multi-core score of 22195 is nearly 70% higher than the AMD’s 13082, and the single-core advantage of 3133 versus 1737 is even more pronounced in percentage terms. For anyone running CPU-bound creative workloads, engineering simulations, or software that scales with high clock speeds, the Intel part is the one to pick from these benchmarks.

The AMD Ryzen 7 8840HS is not without its own territory. It leads in data compression, encryption, extended instruction sets, integer math, and random string sorting. Those are the workloads that benefit from the Zen 4 architecture’s efficiency and instruction handling. The 18.8% encryption lead and 21.8% random string sorting lead are meaningful for file server duties, database work, or any environment handling lots of encrypted traffic. The AMD part also does this at a 28W TDP compared to Intel’s 65W, which the benchmark scores do not capture but the specification table does.

Neither chip is dramatically ahead in aggregate. The AMD Ryzen 7 8840HS has a 33667 average benchmark score versus Intel’s 33206, a difference of about 1.4%, and both sit within 0.4% of their nearest rivals in the ranking data. The Intel Core i7-14701E’s nearest rival is the AMD Ryzen 9 PRO 6950H at a 0% delta, while the AMD Ryzen 7 8840HS’s nearest rival is the AMD Ryzen 5 7645HX, also at 0%. The practical takeaway: pick based on the specific workload mix, not on overall averages.

Where Each One Wins

Intel Core i7-14701E wins for: rendering (Cinebench R23 multi-core 22195 vs 13082), single-core responsiveness (Cinebench R23 single-core 3133 vs 1737, PassMark single-thread 4305 vs 3626), physics simulation (PassMark physics 2399 vs 1149), prime number computation (176 vs 79), floating point math (61873 vs 52582), and the overall PassMark multithread score (26112 vs 24990). This is the processor for CPU-heavy productivity, 3D rendering, and any task that hammered all cores with floating point operations.

AMD Ryzen 7 8840HS wins for: data compression (292888 vs 282939), data encryption (17650 vs 14862), extended instruction workloads (20714 vs 18528), integer math (90382 vs 81325), and random string sorting (35517 vs 29158). These are the workloads found in file archiving, secure communications, cryptographic hashing, and text processing. The AMD part also carries integrated Radeon 780M graphics, which is a more capable integrated solution than Intel’s UHD Graphics 770 for light GPU duties, though the benchmark data does not directly compare iGPU performance.

The market segment difference reinforces this split: the AMD Ryzen 7 8840HS is a mobile part on AMD Socket FP8, while the Intel Core i7-14701E is a desktop part on Intel Socket 1700. The Intel chip is designed to run at a 65W TDP in a desktop environment; the AMD chip is built for 28W mobile systems. That changes where each can physically be used.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 8840HS uses the Zen 4 architecture on a 4nm process from TSMC, with the Hawk Point codename. It packs 25,000 million transistors into a 178 mm² die. The Intel Core i7-14701E uses the Raptor Lake architecture on a 10nm process from Intel, with the Raptor Lake-R codename, on a larger 257 mm² die with no transistor count listed.

Cache layouts differ significantly. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. That larger L3 cache on Intel is a major reason for its single-core and Cinebench wins — more data can stay resident on-die. Neither part has a 3D V-Cache option listed.

Memory support is another architectural split. The AMD Ryzen 7 8840HS supports DDR5 only, dual-channel, with a rated memory bandwidth of 89.6 GB/s and no ECC support. The Intel Core i7-14701E supports both DDR4 and DDR5, dual-channel, with no memory bandwidth figure listed but with ECC memory support enabled. The Intel part also steps up to PCIe Gen 5 with 16 lanes, while the AMD part uses PCIe Gen 4 with 20 lanes.

The integrated graphics differ as well: AMD uses the Radeon 780M, while Intel uses UHD Graphics 770. The AMD part is fabricated by TSMC, the Intel part by Intel’s own fabs. Production status is active for both, but the release dates are about seven months apart — AMD on 2023-12-05 and Intel on 2024-06-30.

The core and thread counts are identical at 8 and 16, and neither has an unlocked multiplier. The Intel part has a higher boost clock by 0.30 GHz but a lower base clock by 0.70 GHz. The AMD part is smaller in die size and uses less power, while the Intel part has more cache at every level and supports both DDR4 and DDR5 memory. The Intel part also enables ECC memory, which is absent on the AMD side. The PCIe generation and lane count difference is notable: Intel offers Gen 5 connectivity with fewer lanes, while AMD offers Gen 4 with more lanes.
