Architecture Differences

The AMD Ryzen Embedded 8640U is built on the Zen 4 architecture, codenamed Hawk Point, and belongs to the 8000 series. It uses a 4 nm process node manufactured by TSMC. The chip integrates 25,000 million transistors on a 178 mm² die. The Intel Core i9-14901E is based on Raptor Lake, codenamed Raptor Lake-R, part of the Core 14th Gen series. It uses a 10 nm process node from Intel with a die size of 257 mm². The transistor count for the Intel part is not recorded in the database.

Cache hierarchies differ substantially. The AMD processor has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. This gives the Intel part a larger total cache footprint, particularly in L3 where it offers more than double the shared capacity.

Memory support also separates the two. The AMD Ryzen Embedded 8640U supports DDR5 memory over a dual-channel bus with a recorded memory bandwidth of 89.6 GB/s. The Intel Core i9-14901E supports both DDR4 and DDR5 memory over a dual-channel bus, though no memory bandwidth figure is recorded for it. Both support ECC memory.

PCIe connectivity differs by generation and lane count. The AMD part provides PCIe Gen 4 with 20 lanes (CPU only). The Intel part provides PCIe Gen 5 with 16 lanes (CPU only). This means the Intel processor offers a newer PCIe generation but fewer CPU-attached lanes.

Integrated graphics differ as well. The AMD Ryzen Embedded 8640U includes a Radeon 760M, while the Intel Core i9-14901E includes UHD Graphics 770. Both are active production parts, and neither has an unlocked multiplier. The AMD processor was released on 2024-04-01, while the Intel processor was released on 2024-06-30. The AMD part uses AMD Socket FP8, while the Intel part uses Intel Socket 1700.

Head-to-Head Benchmarks

The recorded data includes benchmark scores only for the Intel Core i9-14901E. The AMD Ryzen Embedded 8640U has no benchmark entries in the database, so direct score comparisons are not possible. The Intel processor’s results provide a baseline for its performance profile.

In Cinebench R15, the Intel Core i9-14901E scores 2,595 in multi-core and 366 in single-core. In Cinebench R20, it scores 10,816 multi-core and 1,526 single-core. In Cinebench R23, the multi-core score is 25,753 and the single-core score is 3,635. These scores show a strong scaling from R15 to R23, with the multi-core results improving as the workload increases.

PassMark results for the Intel part show a multi-thread score of 30,298 and a single-thread score of 4,354. Data compression yields 288,777, data encryption yields 18,571, and extended instructions yield 17,249. Integer math scores 112,736, floating point math scores 81,089, and find prime numbers scores 189. Random string sorting scores 39,138, and physics scores 3,041.

The Intel processor’s average benchmark score is 37,911, placing it at the 86th percentile of all CPUs in the database. Its nearest rivals show very close performance. The AMD Ryzen AI 9 HX 370 has an average score of 37,904 with a delta of 0%. The AMD Ryzen 7 9700X scores 37,943 with a delta of -0.1%. The Intel Core 5 211E scores 37,829 with a delta of 0.2%. The AMD Ryzen AI Embedded P132 scores 37,804 with a delta of 0.3%. These deltas indicate that the Intel Core i9-14901E sits within a tight performance cluster where differences are under one percent.

Specification Differences

Where Each One Wins

The Intel Core i9-14901E wins on core count, thread count, boost clock, L2 and L3 cache capacity, PCIe generation, and memory flexibility. Its 8 cores and 16 threads provide higher parallelism than the 6-core, 12-thread AMD part. The 5.60 GHz boost clock gives it a higher peak frequency, and the larger 36 MB shared L3 cache helps with workloads that benefit from substantial on-chip data storage. The PCIe Gen 5 interface supports newer peripherals, and DDR4 support adds compatibility with existing memory platforms. Its recorded benchmark scores confirm strong multi-core and single-core performance, with an average score of 37,911 and an 86th percentile ranking.

The AMD Ryzen Embedded 8640U wins on process node, power efficiency, memory bandwidth, and PCIe lane count. The 4 nm TSMC process is smaller than Intel’s 10 nm node, and the 28 watt TDP is significantly lower than the Intel part’s 65 watts. The 89.6 GB/s memory bandwidth exceeds what is recorded for the Intel part, and the 20 PCIe Gen 4 lanes provide more CPU-attached connectivity than the Intel part’s 16 Gen 5 lanes. The smaller 178 mm² die size also indicates a more compact implementation.

For use cases, the Intel Core i9-14901E suits desktop workloads such as content creation, compilation, and heavy multi-threaded applications where core count and cache capacity dominate. Its benchmark results in Cinebench R23 multi-core (25,753) and PassMark multi-thread (30,298) indicate strong sustained throughput. The AMD Ryzen Embedded 8640U suits mobile or embedded deployments where power draw and process efficiency are priorities, and where the higher memory bandwidth and additional PCIe lanes for Gen 4 devices are advantageous. The lack of benchmark data for the AMD part prevents a direct performance comparison, but the architectural differences define clear strengths for each platform.
