AMD Ryzen 5 PRO 8640HS vs Intel Core i9-14901E Comparison

The benchmark data presents a clear hierarchy between the AMD Ryzen 5 PRO 8640HS and the Intel Core i9-14901E. Across the 17 recorded head-to-head tests, the Intel processor secures 16 wins, establishing a dominant performance lead in nearly every measurable category. The AMD chip claims a single victory, but the margin of that win is narrow while the Intel advantages are frequently substantial.

Head-to-Head Benchmarks

The Intel Core i9-14901E demonstrates its largest advantages in compute-heavy workloads. In the Cinebench suite, the results are consistent and decisive. The Intel part scores 2595 in Cinebench R15 multi-core against 1824 for the AMD, a 29.7% difference. Single-core performance in R15 follows the same pattern, with Intel at 366 and AMD at 257, also a 29.8% gap. The R20 multi-core test shows Intel at 10816 versus 7603, and R20 single-core shows 1526 versus 1073, both representing a 29.7% delta. The R23 multi-core result continues the trend: Intel scores 25753, AMD scores 18104, again a 29.7% margin. R23 single-core has Intel at 3635 and AMD at 2555, a 29.7% difference. These Cinebench results indicate a consistent performance tier separation across both single and multi-threaded rendering workloads.

The PassMark suite reveals where the Intel processor excels most dramatically. The physics test shows Intel at 3041 against AMD's 1043, a 65.7% advantage, the largest delta in the entire dataset. Prime number finding also heavily favors Intel, with a score of 189 versus 71, a 62.4% gap. Floating point math performance is 46.9% higher on Intel, scoring 81089 compared to 43019. Integer math shows Intel at 112736 and AMD at 69839, a 38.1% difference. These results indicate that the Intel chip's architecture provides substantially stronger raw computational throughput in mathematical and physics-based workloads.

The Intel advantage persists in memory and storage-related operations, though with a smaller margin. Data compression scores show Intel at 288777 and AMD at 246446, a 14.7% lead. Data encryption favors Intel at 18571 versus 14962, a 19.4% gap. Random string sorting shows Intel at 39138 and AMD at 30235, a 22.7% difference. The multithreaded PassMark score gives Intel 30298 against AMD's 21465, a 29.2% margin, while the single-thread score shows Intel at 4354 and AMD at 3561, an 18.2% advantage.

The sole AMD victory comes in the extended instructions test. AMD scores 18507, Intel scores 17249, giving AMD a 7.3% lead. This is the only benchmark where the AMD processor outperforms its rival, and the margin is modest compared to the Intel wins elsewhere.

The Verdict

The data directs a straightforward conclusion. The Intel Core i9-14901E is the faster processor in 16 of 17 benchmark comparisons, with its largest wins exceeding 65%. The AMD Ryzen 5 PRO 8640HS holds a single 7.3% advantage in extended instructions. The Intel processor also ranks higher in the overall database, sitting at the 86th percentile against all CPUs, while the AMD chip sits at the 80th percentile. The average benchmark score reinforces this: Intel records 37911, AMD records 28478.

The Intel Core i9-14901E is the choice for workloads that demand maximum multi-threaded throughput, physics calculations, and floating-point math. The AMD Ryzen 5 PRO 8640HS remains relevant only for applications that specifically leverage extended instruction sets, where it holds a measurable edge. For any other general purpose or compute-intensive task, the recorded data favors Intel by a wide margin.

Architecture Differences

The two processors come from different design philosophies and manufacturing processes. The AMD Ryzen 5 PRO 8640HS uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. The Intel Core i9-14901E uses Raptor Lake architecture under the Raptor Lake-R codename, built on a 10 nm process at Intel's own foundry. The die sizes reflect this difference: AMD measures 178 mm² with 25,000 million transistors, while Intel measures 257 mm² with no transistor count recorded in the database.

Core and thread configurations differ significantly. AMD provides 6 cores and 12 threads, while Intel provides 8 cores and 16 threads. Cache hierarchies also diverge. AMD's L1 cache is 64 KB per core, L2 is 1 MB per core, and L3 is 16 MB shared. Intel's L1 is 80 KB per core, L2 is 2 MB per core, and L3 is 36 MB shared. The larger L3 cache on Intel likely contributes to its performance advantage in multi-threaded workloads.

Memory support differs as well. AMD supports DDR5 memory only, while Intel supports both DDR4 and DDR5. AMD records a memory bandwidth of 89.6 GB/s, while Intel's memory bandwidth is not recorded in the database. Both processors support ECC memory. PCIe connectivity differs: AMD uses Gen 4 with 20 CPU-only lanes, Intel uses Gen 5 with 16 CPU-only lanes.

Integrated graphics differentiate the pair. AMD includes the Radeon 760M, while Intel includes UHD Graphics 770. Neither processor has an unlocked multiplier. Market segments also differ, with AMD targeting mobile platforms and Intel targeting desktop platforms. The AMD processor uses the AMD Socket FP7, while Intel uses the Intel Socket 1700.

Specification Differences

The processors differ across several specification fields. Clock speeds show a notable contrast: AMD has a base clock of 3.50 GHz and a boost clock of 4.90 GHz, while Intel has a base clock of 2.80 GHz and a boost clock of 5.60 GHz. The Intel chip reaches a higher boost frequency despite starting from a lower base, which explains its single-thread performance edge.

Thermal design power differs substantially. AMD is rated at 28 W TDP, while Intel is rated at 65 W TDP. This higher power envelope on Intel aligns with its higher performance scores, though the database does not record any power consumption measurements to quantify efficiency.

Release timing and series placement also differ. AMD belongs to the 8000 series and was released on 2024-04-15. Intel belongs to the Core 14th Gen series and was released on 2024-06-30. The AMD part numbers are listed as 100-000001354(FP7r2) and 100-000001382(FP7), while the Intel part number is Q49ESRNJH.

Where Each One Wins

The Intel Core i9-14901E dominates in nearly every workload category represented in the database. Multi-threaded rendering applications benefit from its 29.7% lead in Cinebench R23 multi-core. Physics simulation workloads see the largest advantage, with Intel ahead by 65.7% in the PassMark physics test. Mathematical processing is another strong area: Intel leads floating point math by 46.9% and integer math by 38.1%. Prime number calculations show a 62.4% Intel advantage. Data compression and encryption tasks also favor Intel, with leads of 14.7% and 19.4% respectively. Single-threaded performance, often important for general responsiveness and lightly threaded applications, favors Intel by 18.2%.

The AMD Ryzen 5 PRO 8640HS wins only in the extended instructions benchmark, where it leads by 7.3%. This suggests a narrow use case for workloads that heavily utilize specific instruction set extensions. Outside that specific scenario, the AMD processor does not outperform Intel in any other recorded test.

The overall percentile rankings confirm the spread. Intel sits at the 86th percentile among all CPUs, while AMD sits at the 80th percentile. The average benchmark scores place Intel clearly above AMD, and the nearest rival data shows AMD competing with processors like the Intel Xeon E-2436 and AMD Ryzen 7 PRO 6850HS, while Intel competes with the AMD Ryzen AI 9 HX 370 and AMD Ryzen 7 9700X. The data positions the Intel Core i9-14901E in a higher performance tier, with the AMD Ryzen 5 PRO 8640HS occupying a lower tier that still performs well but cannot match the Intel chip's output in the vast majority of tests.
