AMD Ryzen Embedded 8640U vs Intel Core i7-14701TE Comparison

The AMD Ryzen Embedded 8640U and the Intel Core i7-14701TE occupy different corners of the processor market, one a low-power mobile part and the other a higher-power desktop chip. The data in the database provides a clear picture of how these two processors compare, despite the absence of direct head-to-head benchmark runs. The Intel part, with its eight cores and sixteen threads, is the only one with recorded benchmark scores, placing it in the 78th percentile of all CPUs. The AMD chip, by contrast, has no recorded average benchmark score and sits at the 50th percentile, which is a default position rather than a measured one. This disparity in available data shapes the analysis, but the architectural specifications and the Intel chip's measured performance still allow for a meaningful comparison.

Head-to-Head Benchmarks

No direct head-to-head benchmark results exist in the database for these two processors. The AMD Ryzen Embedded 8640U has an empty benchmark array, meaning no Cinebench or PassMark scores are recorded for it. The Intel Core i7-14701TE, however, has a full suite of sixteen recorded results. This asymmetry means the comparison relies on the Intel part's absolute scores and the architectural differences between the two chips.

The Intel Core i7-14701TE delivers strong multi-threaded performance in the recorded tests. In Cinebench R23, it scores 17035 points in the multi-core test and 2405 points in the single-core test. The Cinebench R20 results show 7154 points multi-core and 1010 points single-core, while the older Cinebench R15 test yields 1716 points multi-core and 242 points single-core. These scores indicate a processor that scales well with thread count, a result of its 8 cores and 16 threads.

PassMark results for the Intel chip reinforce its multi-threaded strengths. The multithread test scores 20042, integer math scores 65792, and floating-point math scores 50219. Data compression reaches 220520, while data encryption hits 11699 and extended instructions score 14354. Single-thread performance in PassMark is 2637, and the physics test scores 1860. Random string sorting finishes at 22760, and the prime numbers test scores 143.

Because the AMD chip has no benchmark scores, its wins cannot be quantified. The database shows zero wins for the AMD part and zero wins for the Intel part in the head-to-head section, which reflects the absence of direct tests. The only measurable performance data belongs to the Intel chip, so the analysis of where each processor wins must be inferred from specifications and the Intel chip's recorded results.

Where Each One Wins

The Intel Core i7-14701TE wins in every measured performance category because it is the only chip with recorded scores. Its 8 cores and 16 threads provide a substantial advantage in multi-threaded workloads, as shown by the Cinebench R23 multi-core score of 17035. The PassMark multithread score of 20042 further confirms its capability in parallel tasks like video rendering, scientific computation, and server-side processing. The high integer math score of 65792 and floating-point math score of 50219 indicate strength in general-purpose computing and numerical workloads.

The AMD Ryzen Embedded 8640U wins in power efficiency and mobility. Its 28-watt TDP is significantly lower than the Intel chip's 45-watt TDP, making it suitable for fanless or passively cooled embedded systems. The AMD chip uses the FP8 socket, which is designed for mobile and embedded applications, whereas the Intel chip uses Socket 1700, a desktop platform. The AMD chip also benefits from a smaller process node, 4 nm from TSMC, compared to Intel's 10 nm process. This node advantage typically translates to lower power draw per transistor, though the database does not provide direct power consumption measurements beyond TDP.

The AMD chip also wins in memory bandwidth efficiency per watt. It supports DDR5 memory with a measured bandwidth of 89.6 GB/s, while the Intel chip supports both DDR4 and DDR5 but has no recorded memory bandwidth figure. The AMD chip's L3 cache is 16 MB shared, which is smaller than the Intel chip's 33 MB shared L3 cache, but the AMD chip's smaller cache may be offset by its lower power envelope in embedded use cases.

Architecture Differences

The two processors diverge sharply in architecture. The AMD Ryzen Embedded 8640U uses the Zen 4 architecture, codenamed Hawk Point, and is built on a 4 nm process by TSMC. It contains 25,000 million transistors on a 178 mm² die. The Intel Core i7-14701TE uses the Raptor Lake architecture, specifically Raptor Lake-R, and is built on a 10 nm process by Intel. Its die size is 257 mm², and the database does not list its transistor count.

Core and thread counts differ: the AMD chip has 6 cores and 12 threads, while the Intel chip has 8 cores and 16 threads. The AMD chip's base clock is 3.50 GHz with a boost clock of 4.90 GHz. The Intel chip has a base clock of 2.10 GHz and a boost clock of 5.20 GHz. The Intel chip's higher boost clock gives it a single-thread advantage, as reflected in its Cinebench R23 single-core score of 2405. The AMD chip's higher base clock suggests better sustained performance at lower power, though no direct measurements exist.

Cache hierarchies differ significantly. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Intel chip's larger L3 cache helps in multi-threaded workloads that reuse data, which may explain its strong Cinebench multi-core scores.

Memory support varies. The AMD chip supports only DDR5 memory in a dual-channel configuration with a measured bandwidth of 89.6 GB/s. The Intel chip supports both DDR4 and DDR5, also dual-channel, but has no recorded bandwidth figure. Both chips support ECC memory, which is important for embedded and server reliability.

PCI Express capabilities differ. The AMD chip provides Gen 4 with 20 lanes (CPU only), while the Intel chip provides Gen 5 with 16 lanes (CPU only). The Intel chip's Gen 5 support doubles the bandwidth per lane compared to Gen 4, which benefits high-throughput devices like GPUs and NVMe storage. However, the AMD chip offers more total lanes, which may suit systems with multiple expansion devices.

Integrated graphics also differ. The AMD chip includes the Radeon 760M, while the Intel chip includes the UHD Graphics 770. The database does not provide benchmark scores for either GPU, so performance cannot be quantified, but the Radeon 760M is generally positioned for lighter gaming and media tasks, while the UHD Graphics 770 handles basic display output and video decode.

Market segments and sockets reinforce their different roles. The AMD chip is a mobile part on AMD Socket FP8, released on 2024-04-01. The Intel chip is a desktop part on Intel Socket 1700, released on 2024-06-30. The AMD chip belongs to the 8000 series and Ryzen Embedded generation, while the Intel chip belongs to the Core 14th Gen series. Both are currently active in production, and neither has an unlocked multiplier.

The Verdict

The data indicates the Intel Core i7-14701TE is the stronger performer in every measured benchmark category. Its 8 cores and 16 threads, combined with a 5.20 GHz boost clock and 33 MB of shared L3 cache, produce a Cinebench R23 multi-core score of 17035 and a PassMark multithread score of 20042. These results place it in the 78th percentile of all CPUs, with an average benchmark score of 26013, which is close to its nearest rivals: the AMD Ryzen AI 5 340 (25981, 0.1% delta), the AMD Ryzen 5 8640HS (26106, -0.4% delta), the AMD Ryzen 5 PRO 5655GE (25880, 0.5% delta), and the AMD Ryzen 5 8540U (26187, -0.7% delta). The Intel chip essentially matches these rivals within a 1% margin, indicating it is a competitive mid-range desktop processor.

The AMD Ryzen Embedded 8640U, however, is a different class of product. It targets embedded systems where power efficiency matters more than raw throughput. Its 28-watt TDP, 4 nm process, and support for 89.6 GB/s DDR5 bandwidth make it a suitable choice for compact industrial PCs, thin clients, and edge computing devices. The lack of benchmark scores in the database means its performance cannot be directly compared, but its architectural advantages in process node and power consumption are clear.

For users prioritizing multi-threaded performance, the Intel chip is the obvious choice based on recorded data. For embedded deployments where heat and power constraints dominate, the AMD chip's lower TDP and smaller process node make it the more practical option. The decision rests on whether the workload demands maximum compute or minimal power draw.
