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

AMD Ryzen Embedded 8640U and Intel Core i7-14701E occupy different corners of the processor market, yet both serve as embedded and industrial compute options. The Ryzen part is a 6-core, 12-thread mobile-class chip built on a 4 nm process, while the Intel part is an 8-core, 16-thread desktop-class chip built on a 10 nm process. The database contains a full benchmark record for the Intel i7-14701E, including Cinebench and Passmark results, but no benchmark scores for the AMD 8640U. The AMD unit also lacks nearest rival data and an average benchmark score. The Intel unit, by contrast, holds an average benchmark score of 33206 and sits at the 83rd percentile among all CPUs tracked. The AMD part sits at the 50th percentile with an average score of zero in the record. This asymmetry means the head-to-head analysis relies on the Intel part’s measured performance and the architectural and specification differences recorded for both.

Where Each One Wins

The Intel Core i7-14701E wins every benchmark category where recorded data exists. With 8 cores and 16 threads against the AMD part’s 6 cores and 12 threads, the Intel chip holds a thread-count advantage of two cores and four threads. The Intel chip also boosts to 5.40 GHz, which is 0.50 GHz higher than the AMD part’s 4.90 GHz maximum. That combination of more cores and a higher boost clock shows up across the Cinebench suite. In Cinebench R23 multi-core, the Intel chip scores 22195. In single-core, it scores 3133. The AMD part has no recorded score in the database for any of these tests, so the data cannot show a single win condition for the AMD side.

The Passmark results reinforce the Intel advantage. The Intel chip scores 26112 in Passmark multithread, 4305 in Passmark single-thread, and 81325 in integer math. The AMD part has no Passmark entries. The Intel chip also wins in specialized workloads: 282939 in data compression, 14862 in data encryption, 18528 in extended instructions, 176 in prime number finding, 61873 in floating point math, 2399 in physics, and 29158 in random string sorting. Every one of those results belongs to the Intel part. The AMD part’s record is empty, so the database indicates no measured win for the Ryzen Embedded 8640U.

The use-case split therefore favors the Intel chip for any workload that relies on multi-threaded throughput, single-thread responsiveness, or math-heavy operations. The AMD part’s potential advantages lie outside the benchmark record: it is a mobile-market chip with a 28 W TDP, while the Intel part is a desktop-market chip with a 65 W TDP. For power-constrained embedded systems, the AMD part’s lower thermal envelope could be the deciding factor, but the database contains no performance measurements to confirm how that power draw translates into work done. The data shows the Intel chip winning every recorded test, while the AMD chip wins no recorded test.

Architecture Differences

The two processors come from different design schools. The AMD Ryzen Embedded 8640U uses Zen 4 architecture under the Hawk Point codename, part of the Ryzen Embedded 8000 series. It is fabricated by TSMC on a 4 nm process with 25,000 million transistors on a 178 mm² die. The Intel Core i7-14701E uses Raptor Lake architecture under the Raptor Lake-R codename, part of the Core 14th Gen series. It is fabricated by Intel on a 10 nm process with a 257 mm² die, though the transistor count is not recorded in the database.

Cache hierarchies differ substantially. The AMD part provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. That gives the Intel chip a larger L3 pool by 17 MB and double the per-core L2. For workloads that repeatedly access a working set larger than 16 MB, the Intel chip’s 33 MB L3 could reduce memory traffic, though the database does not include a cache-specific benchmark.

Memory support also differs. The AMD chip supports DDR5 only, while the Intel chip supports both DDR4 and DDR5. The AMD part records a memory bandwidth of 89.6 GB/s; the Intel part has no bandwidth figure in the database. Both run dual-channel memory buses. Both support ECC memory, which matters for embedded and industrial reliability scenarios. The AMD chip offers PCIe Gen 4 with 20 lanes from the CPU. The Intel chip offers PCIe Gen 5 with 16 lanes from the CPU. That means the Intel part provides a newer PCIe generation but fewer CPU-attached lanes.

The integrated graphics differ as well. The AMD part uses the Radeon 760M, while the Intel part uses UHD Graphics 770. The database does not include graphics benchmarks for either chip, so the comparison stops at the model names. The AMD part is a mobile-market chip on AMD Socket FP8, while the Intel part is a desktop-market chip on Intel Socket 1700. The AMD part has no recorded launch MSRP, and the Intel part has no recorded launch MSRP either. The Intel part is identified by part number Q49FSRNJK; the AMD part’s part number is unknown. Neither chip has an unlocked multiplier, so overclocking is not a supported differentiator.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark entries between the two processors. The only recorded benchmark set belongs to the Intel Core i7-14701E. Comparing the Intel chip’s scores against its nearest rivals provides context for where it lands. The Intel chip’s average benchmark score is 33206. Its nearest rival, the AMD Ryzen 9 PRO 6950H, scores 33201, a delta of 0 percent. The AMD Ryzen 5 8645HS scores 33244, a delta of negative 0.1 percent, meaning it sits slightly above the Intel chip. The AMD Ryzen 7 7745HX scores 33091, a delta of 0.3 percent, placing it just below. The Intel Core i7-13650HX scores 33089, a delta of 0.4 percent, also just below. The Intel i7-14701E therefore sits in a tight cluster where the four nearest rivals are all within 0.4 percent of its average score.

The Cinebench R23 multi-core score of 22195 puts the Intel chip in strong territory for a 65 W embedded processor. The single-core score of 3133 indicates solid per-thread performance, aided by the 5.40 GHz boost clock. The Cinebench R20 results follow the same pattern: 9321 multi-core and 1315 single-core. The older Cinebench R15 results show 2237 multi-core and 315 single-core. The Passmark suite adds more texture. The multithread score of 26112 and single-thread score of 4305 both point to a balanced processor. The integer math score of 81325 and floating point math score of 61873 show strength in arithmetic workloads. The data compression score of 282939 is the highest single Passmark entry in the record. The encryption score of 14862 and extended instructions score of 18528 complete the picture.

Without any AMD benchmark scores, the head-to-head cannot show a single AMD win. The AMD part’s 50th percentile ranking among all CPUs, paired with an average benchmark score of zero, confirms the absence of measured data. The Intel part’s 83rd percentile ranking reflects its position among all tracked CPUs. The nearest rival deltas show that the Intel chip is not an outlier; it trades places with several AMD mobile and desktop parts within a fraction of a percent. The data indicates that the Intel i7-14701E delivers competitive average performance against those rivals, and the AMD Ryzen Embedded 8640U has no recorded performance data to place it in that same comparison.

The Verdict

The data supports a clear pick for anyone who needs measured performance: the Intel Core i7-14701E. It holds every recorded benchmark score in the database, covers both Cinebench and Passmark suites, and ranks at the 83rd percentile among all CPUs. Its 8 cores, 16 threads, and 5.40 GHz boost clock provide the foundation for those results. The AMD Ryzen Embedded 8640U offers no recorded benchmark scores, no nearest rival data, and a 50th percentile ranking with an average score of zero. The database cannot confirm any performance advantage for the AMD part.

The AMD part does hold specification advantages that the benchmark record does not capture. Its 28 W TDP is less than half the Intel chip’s 65 W TDP. Its 4 nm TSMC process is smaller than Intel’s 10 nm process. Its 89.6 GB/s memory bandwidth is recorded, while the Intel part’s bandwidth is not. Its PCIe Gen 4 with 20 lanes offers more CPU-attached lanes than the Intel part’s PCIe Gen 5 with 16 lanes. For systems where power draw and platform flexibility matter more than raw throughput, the AMD part could be the appropriate choice, but that conclusion comes from specifications, not measurements.

The Intel part, by contrast, wins on every recorded metric and brings larger caches, a higher boost clock, more cores, and support for both DDR4 and DDR5. The 33 MB shared L3 doubles the AMD part’s 16 MB L3. The 2 MB per-core L2 doubles the AMD part’s 1 MB per-core L2. The Intel part also supports PCIe Gen 5, which the AMD part does not. The verdict from the database is straightforward: the Intel i7-14701E is the only one of the two with measured performance, and that measured performance ranks in the 83rd percentile. The AMD 8640U remains an unmeasured alternative with a lower power envelope and a smaller process node.
