AMD Ryzen Embedded 8640U vs Intel Core Ultra 5 336H Comparison

AMD Ryzen Embedded 8640U vs Intel Core Ultra 5 336H

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen Embedded 8640U and the Intel Core Ultra 5 336H, and the AMD processor has no recorded benchmark scores or nearest rivals in the dataset. All measurable performance data in this analysis comes from the Intel Core Ultra 5 336H’s 17 benchmark entries, its average score of 34,485, and its 84th percentile ranking among all CPUs. The AMD side is limited to architectural specifications, meaning the comparative analysis must rely on structural differences rather than empirical performance validation.

Where Each One Wins

The Intel Core Ultra 5 336H is the only processor in this pairing with recorded benchmark results, so it wins every measured category by default. Its Cinebench R23 multi-core score of 23,991 and single-core score of 3,387 place it in the 84th percentile of all CPUs, and its average benchmark score of 34,485 is nearly identical to the Intel Core i7-13700HX at 34,554, a delta of -0.2%. The Intel chip also leads in PassMark integer math at 62,070, floating point math at 82,415, and extended instructions at 24,542, indicating strong general-purpose compute for both integer-heavy and floating-point-heavy workloads.

The AMD Ryzen Embedded 8640U cannot claim a benchmark win because the database has zero recorded scores for it. What it does offer is a lower thermal design power of 28 watts versus the Intel’s 25 watts, which is a smaller difference than the core count disparity might suggest. The AMD processor uses 6 cores and 12 threads, while the Intel part uses 16 cores and 16 threads, so the Intel chip should dominate multi-threaded workloads based on core count alone. The AMD’s advantage, if any, would come from its higher boost clock of 4.90 GHz versus the Intel’s 4.60 GHz, which could help in lightly threaded tasks, but no benchmark data confirms this.

Architecture Differences

The two processors come from different manufacturing generations and foundries. The AMD Ryzen Embedded 8640U uses Zen 4 architecture on Hawk Point, fabricated on a 4 nm process by TSMC with 25,000 million transistors on a 178 mm² die. The Intel Core Ultra 5 336H uses Panther Lake architecture, fabricated on a 3 nm process by Intel, with no transistor count or die size recorded in the database. This makes the Intel part a newer, denser process, while the AMD part has a documented transistor budget and physical size.

Core configurations differ substantially. The AMD chip has 6 cores and 12 threads, relying on simultaneous multithreading to reach 12 threads. The Intel chip has 16 cores and 16 threads, meaning it uses no multithreading and instead relies on a higher physical core count. Cache hierarchies also differ: the AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel chip’s larger per-core L1 and L2 caches could reduce latency in repeated access patterns, while the AMD chip’s 16 MB L3 is slightly smaller than Intel’s 18 MB.

Memory support differs in both type and bandwidth. The AMD processor supports DDR5 on a dual-channel bus with 89.6 GB/s bandwidth and ECC memory. The Intel processor supports both DDR5 and LPDDR5X on a dual-channel bus with 115.2 GB/s bandwidth and no ECC support. The Intel part’s higher memory bandwidth, 115.2 GB/s versus 89.6 GB/s, gives it an advantage in memory-bound workloads, assuming the platform uses memory capable of reaching that figure. The AMD part’s ECC support makes it suitable for error-sensitive embedded applications, which aligns with its "Embedded" market segment.

PCIe connectivity also differs. The AMD chip uses Gen 4 with 20 CPU lanes, while the Intel chip uses Gen 5 with 12 CPU lanes. The Intel part’s Gen 5 interface provides higher per-lane bandwidth, but the AMD part offers more lanes, which could matter for systems needing many Gen 4 devices. Integrated graphics differ as well: the AMD chip uses Radeon 760M, while the Intel chip uses Intel Xe3 Graphics. Neither has benchmark scores for graphics in the database, so no performance judgment is possible.

The Verdict

Based on the recorded data, the Intel Core Ultra 5 336H is the clear choice for any workload that benefits from multi-threading, given its 16 cores and 16 threads versus the AMD’s 6 cores and 12 threads. Its 84th percentile ranking and average score of 34,485 place it in the same performance class as the Intel Core i7-13700HX (34,554, -0.2% delta) and slightly ahead of the AMD Ryzen 7 3700X (34,260, 0.7% delta). The Intel chip’s higher memory bandwidth of 115.2 GB/s and larger L3 cache of 18 MB further support its case for compute-heavy applications.

The AMD Ryzen Embedded 8640U has no benchmark scores, so the database cannot confirm any performance advantage. What the data does show is that it is a 28-watt, 6-core, 12-thread processor with ECC memory support and a 4.90 GHz boost clock, built on a 4 nm TSMC process. For embedded use cases where ECC is mandatory and power draw is a concern, the AMD part’s specifications are relevant, but no empirical evidence in the database supports a performance recommendation.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for these two processors, and the AMD Ryzen Embedded 8640U has no benchmark results at all. Therefore, the only analyzable scores belong to the Intel Core Ultra 5 336H. Its Cinebench R23 multi-core score of 23,991 and single-core score of 3,387 show a strong multi-core advantage relative to its own single-core result, consistent with its 16-core design. In Cinebench R20, the Intel chip scores 10,076 multi-core and 1,422 single-core, and in Cinebench R15 it scores 2,418 multi-core and 341 single-core.

PassMark results for the Intel chip show a wide spread across workload types. Integer math scores 62,070, floating point math scores 82,415, and extended instructions score 24,542. Data compression scores 280,340, while data encryption scores 21,291. Find prime numbers scores 299, random string sorting scores 34,402, and physics scores 2,682. The multithread score is 28,545, and the single-thread score is 4,013. These figures indicate that the Intel processor is strongest in floating point math and data compression, while prime number finding is the weakest measured area.

The Intel chip’s nearest rivals confirm its positioning. The Intel Core i7-13700HX scores 34,554, which is 0.2% higher. The Intel Core i5-13450HX scores 34,333, which is 0.4% lower. The AMD Ryzen 7 3700X scores 34,260, which is 0.7% lower, and the AMD Ryzen AI 7 350 scores 34,222, which is 0.8% lower. These deltas are small, placing the Intel Core Ultra 5 336H in a tight cluster of similarly performing processors. Without AMD Ryzen Embedded 8640U scores, the database cannot establish where the AMD chip falls relative to this cluster.
