AMD Ryzen Embedded 8640U vs Intel Core 7 350 Comparison

Head-to-Head Benchmarks

The Intel Core 7 350 is the only processor in this comparison with recorded benchmark scores in the database. The AMD Ryzen Embedded 8640U has no benchmark entries, so all numerical comparisons rely on the Intel part’s measured results and its position against its nearest rivals. The Core 7 350 holds a 71st percentile rank across all CPUs, with an average benchmark score of 17,779 points.

In Cinebench R23, the Core 7 350 posts 8,030 points in the multi-core test and 2,046 points in the single-core test. The multi-core result places it close to the Intel Core 5 221TE, which averages 17,860 points overall, a delta of -0.5 percent relative to the Core 7 350. That means the Core 7 350 trails the Core 5 221TE by half a percent in average score, a negligible gap. Against the AMD EPYC 9374F, which averages 17,693 points, the Core 7 350 leads by 0.5 percent. The AMD Ryzen 5 3600XT and Intel Core 5 120U average 17,891 and 17,898 points respectively, putting the Core 7 350 behind both by 0.6 and 0.7 percent.

In Cinebench R20, the Core 7 350 scores 5,373 multi-core and 758 single-core. The R15 results show 1,220 multi-core and 292 single-core. PassMark tests reveal stronger performance in specific workloads: data compression scores 143,123, data encryption reaches 10,933, and extended instructions hit 12,045. Integer math finishes at 33,734, floating point math at 42,809, and prime number finding at 107. The multithread score is 15,170, while the single-thread score is 4,100. Physics tests produce 1,173 points, and random string sorting yields 17,238.

The lack of recorded benchmarks for the AMD Ryzen Embedded 8640U means the database cannot produce a direct head-to-head score comparison. What can be compared are the architectural specifications and the Intel part’s measured standing relative to its listed rivals.

Where Each One Wins

The Intel Core 7 350 demonstrates its strongest results in data-heavy workloads. The PassMark data compression score of 143,123 is by far the highest single value among its recorded tests, indicating that compression tasks draw heavily on its cache and memory architecture. Data encryption at 10,933 and extended instructions at 12,045 also point to solid throughput in cryptographic and SIMD-style operations. The floating point math score of 42,809 outpaces the integer math score of 33,734, suggesting the processor handles floating-point calculations more efficiently than pure integer work.

The Core 7 350’s Cinebench results indicate balanced performance across both multi-core and single-core rendering tasks. Its R23 multi-core score of 8,030 is roughly four times its single-core score of 2,046, a ratio consistent with a six-core processor without simultaneous multithreading. The R20 and R15 results follow the same pattern, with multi-core scores of 5,373 and 1,220 respectively, and single-core scores of 758 and 292.

The AMD Ryzen Embedded 8640U offers no measured wins in the database because no benchmark scores are recorded for it. However, its specifications suggest where it could excel if tested. It features 12 threads from six cores, doubling the thread count of the Intel part. Its base clock of 3.50 GHz is substantially higher than the Intel part’s 1.50 GHz, and its boost clock of 4.90 GHz edges out the Intel part’s 4.80 GHz. The Ryzen part also supports dual-channel DDR5 memory with 89.6 GB/s of bandwidth, compared to the Intel part’s single-channel memory bus at 59.7 GB/s. These figures indicate the AMD processor would likely dominate in heavily threaded workloads and memory-bandwidth-sensitive tasks, though the database lacks actual scores to confirm this.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen Embedded 8640U uses a 4 nm process from TSMC, while the Intel Core 7 350 uses a 3 nm process from Intel. The AMD chip is built on Zen 4 architecture under the Hawk Point codename, part of the 8000 series. The Intel chip uses the Wildcat Lake codename and belongs to the Core 5 generation. The AMD processor packs 25,000 million transistors on a 178 mm² die, while the database records no transistor count or die size for the Intel part.

Core counts match at six physical cores, but threading differs sharply. The AMD part supports 12 threads via simultaneous multithreading, while the Intel part runs six threads with no hyper-threading. Cache layouts also diverge. The AMD chip allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip allocates 192 KB of L1 per core, 2.5 MB of L2 per core, and only 6 MB of shared L3 cache. The Intel part’s larger per-core L1 and L2 caches could aid single-threaded latency, but its smaller L3 pool may hurt workloads that rely on shared data.

Memory support differs in both type and bus width. The AMD part supports DDR5 over a dual-channel bus, delivering 89.6 GB/s of bandwidth. The Intel part supports DDR5 and LPDDR5X over a single-channel bus, delivering 59.7 GB/s. The AMD part also supports ECC memory, while the Intel part does not. PCIe lane counts favor AMD as well: 20 Gen 4 lanes on the CPU, versus 6 Gen 4 lanes on the Intel part.

Integrated graphics differ. The AMD chip uses a Radeon 760M, while the Intel chip uses Intel Xe3 Graphics with 2 Xe cores. Power envelopes are distinct, with the AMD part rated at 28 W TDP and the Intel part at 15 W TDP. The Intel part uses the Intel BGA 1516 socket, while the AMD part uses AMD Socket FP8. Neither processor has an unlocked multiplier.

The Intel part carries a launch MSRP of $469 and a part number of SAE3F. The AMD part has no recorded launch MSRP and an unknown part number. The AMD processor released on April 1, 2024, while the Intel processor’s release date is April 15, 2026. Both are listed as active production parts and target the mobile market segment.

The Verdict

The recorded data favors the Intel Core 7 350 for any workload that has been actually measured. Its Cinebench R23 multi-core score of 8,030 and single-core score of 2,046, combined with a 71st percentile rank and an average score of 17,779, place it in a competitive position against its nearest rivals. The processor’s PassMark results in data compression, encryption, and extended instructions show particular strength in data-oriented tasks. Its 15 W TDP and single-channel memory bus make it suitable for power-constrained mobile designs where lower bandwidth is acceptable.

The AMD Ryzen Embedded 8640U cannot be recommended on the basis of measured performance because the database contains no benchmark scores for it. Its specifications, however, indicate a different set of strengths. The 12 threads, dual-channel memory at 89.6 GB/s, ECC support, and 20 PCIe Gen 4 lanes make it architecturally suited for embedded workloads that demand higher memory throughput, more PCIe connectivity, and error-correcting memory. The 28 W TDP is higher than the Intel part’s 15 W, reflecting the AMD chip’s higher base clock and wider memory interface.

The choice between the two depends on whether measured data or architectural capability matters more. The Intel Core 7 350 delivers confirmed benchmark results across rendering and compute workloads, with a strong percentile rank and tight competition among its nearest rivals. The AMD Ryzen Embedded 8640U offers a broader memory bus, ECC support, more PCIe lanes, and twice the thread count, but none of that is backed by recorded scores in the database. For users who require verified performance numbers, the Intel part is the only one with data. For users who need ECC memory, dual-channel bandwidth, or extensive PCIe connectivity, the AMD part’s specifications provide those features on paper. The database records no direct head-to-head benchmark between the two, so any performance comparison beyond the Intel part’s measured results remains speculative.
