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

Head-to-Head Benchmarks

The benchmark data shows a clear overall advantage for the Intel Core i7-14701E, which wins 13 of the 17 recorded comparisons against the AMD Ryzen 7 PRO 8840U. The AMD part claims 4 wins, but the margins in most of the Intel victories are substantial, particularly in multi-threaded workloads and physics simulations.

Starting with the Cinebench suite, the Intel chip dominates across every version. In Cinebench R23 multi-core, the Intel scores 22,195 against AMD's 20,254, a difference of 8.7%. The single-core R23 result shows 3,133 for Intel versus 2,859 for AMD, again an 8.7% gap. These margins repeat consistently through Cinebench R15 and R20, with multi-core deltas of 8.8% and 8.7% respectively, and single-core deltas of 8.6% and 8.7%. The pattern is uniform: Intel leads by roughly 8.6% to 8.8% across all Cinebench iterations.

The PassMark multi-thread test reinforces this trend. Intel scores 26,112 against AMD's 23,850, an 8.7% lead. The single-thread result shows an even larger gap: Intel at 4,305 versus AMD at 3,641, a 15.4% advantage. This larger single-thread delta suggests the Intel architecture has a meaningful per-core performance edge, not just a multi-core advantage.

The most lopsided results appear in two specific workloads. The PassMark physics test shows Intel at 2,399 versus AMD at 1,174, a massive 51.1% difference. Similarly, the find prime numbers test gives Intel a 176 score against AMD's 76, a 56.8% gap. These two tests indicate that the Intel processor handles certain integer-heavy, single-threaded calculations with far greater efficiency.

Floating-point math also favors Intel: 61,873 versus 50,746, an 18% lead. Data compression follows with Intel at 282,939 versus AMD's 272,664, a smaller 3.6% advantage.

The AMD Ryzen 7 PRO 8840U does secure several wins. The most notable is data encryption, where AMD scores 16,441 against Intel's 14,862, a 10.6% lead. Random string sorting also goes to AMD: 33,109 versus 29,158, a 13.6% margin. Integer math shows AMD ahead with 88,339 against Intel's 81,325, an 8.6% advantage. Extended instructions round out AMD's wins: 19,132 versus 18,528, a 3.3% gap.

The average benchmark score in the database puts Intel at 33,206 and AMD at 32,233, a difference of 3.0%. Both processors sit at the 83rd percentile among all CPUs. Intel's nearest rivals include AMD Ryzen 9 PRO 6950H and Ryzen 5 8645HS with deltas of 0% and -0.1%, while AMD's nearest rivals include Intel Core i9-11900 and Core i5-14400F with deltas of 0% and -0.1%. The overall average scores place these two chips in a similar performance class, despite the head-to-head deltas favoring Intel in most individual tests.

Architecture Differences

The two processors come from fundamentally different design approaches. The AMD Ryzen 7 PRO 8840U 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. This process difference is significant, as the smaller 4 nm node allows AMD to fit 25,000 million transistors on a 178 mm² die, while Intel's 10 nm process produces a larger 257 mm² die.

Both chips have 8 cores and 16 threads, so the thread count is identical. However, the cache layouts differ markedly. AMD provides 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The larger L3 cache on Intel, more than double AMD's, likely contributes to its advantage in workloads that benefit from larger working sets.

Clock speeds also differ. AMD has a base clock of 3.30 GHz and a boost clock of 5.10 GHz. Intel has a base clock of 2.60 GHz but a boost clock of 5.40 GHz. The higher boost clock on Intel helps explain its single-thread performance lead. The base clock difference reflects different power targets: AMD runs at 28 W TDP, while Intel runs at 65 W TDP. This power envelope difference is substantial and aligns with their intended market segments.

Memory support differs as well. AMD supports DDR5 only, with dual-channel memory and a recorded memory bandwidth of 89.6 GB/s. Intel supports both DDR4 and DDR5, also dual-channel, with no bandwidth figure recorded. Both support ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 20 lanes from the CPU, while Intel provides Gen 5 with 16 lanes. The newer PCIe generation on Intel offers higher per-lane bandwidth, though AMD provides more total lanes.

Integrated graphics differ: AMD uses Radeon 780M, while Intel uses UHD Graphics 770. The socket and market segment also separate these parts. AMD uses Socket FP7 and targets the mobile segment, while Intel uses Socket 1700 and targets desktop. The release dates show AMD launched on April 15, 2024, and Intel on June 30, 2024, with both listed as active production parts.

The Verdict

The data supports a straightforward split based on workload and platform. For anyone building or buying a desktop system with access to standard desktop power delivery, the Intel Core i7-14701E delivers higher raw performance in the majority of recorded benchmarks. Its 15.4% single-thread lead, 18% floating-point lead, and massive advantages in physics and prime number finding make it the stronger choice for general computing, simulation, and math-heavy tasks.

For mobile or low-power applications, the AMD Ryzen 7 PRO 8840U offers a compelling alternative. Its 28 W TDP, versus Intel's 65 W, means it fits into thinner, lighter systems with less cooling overhead. The AMD chip also wins in encryption, integer math, and random string sorting, making it competitive for specific security or data-processing workloads. Its smaller 4 nm process and larger transistor count on a smaller die suggest better power efficiency per unit of silicon.

The average benchmark scores place these chips close together, with Intel at 33,206 and AMD at 32,233. The 3% overall difference is modest. Yet the head-to-head deltas show that Intel's wins tend to be larger and more consistent across the Cinebench suite and multi-thread tests. AMD's wins are concentrated in fewer, more specialized areas.

Choose the Intel part for desktop builds where power is not a constraint and single-thread or physics-heavy performance matters. Choose the AMD part for mobile systems where power draw is critical and encryption or integer workloads dominate.

Where Each One Wins

The Intel Core i7-14701E wins in every Cinebench test, all three versions covering multi-core and single-core. It also wins PassMark multi-thread, single-thread, physics, floating-point math, data compression, and find prime numbers. The physics and prime number wins are the largest, at 51.1% and 56.8% respectively. These results make Intel the clear choice for rendering, simulation, physics engines, and any workload that stresses floating-point arithmetic or single-threaded integer loops.

The AMD Ryzen 7 PRO 8840U wins in data encryption, random string sorting, integer math, and extended instructions. The encryption win of 10.6% and string sorting win of 13.6% are particularly notable. These results suggest AMD handles certain data transformation and security-related workloads more efficiently. The integer math win of 8.6% shows AMD has a strong core design for general integer operations, even though Intel dominates in the physics and prime number tests that also involve integer work.

The power envelope difference further shapes the use-case split. At 28 W TDP, AMD is suited for compact mobile systems where thermal and power budgets are tight. At 65 W TDP, Intel requires more substantial cooling but offers higher sustained performance in desktop scenarios. The mobile versus desktop market segments align with these power profiles.
