AMD Ryzen Embedded 8645HS vs Intel Core Ultra 7 270HX Plus Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Ryzen Embedded 8645HS versus the Intel Core Ultra 7 270HX Plus. The AMD processor has no benchmark scores listed, while the Intel processor has a full suite of Cinebench and PassMark results. The absence of comparable data means the analysis must rely on the Intel processor's recorded performance and the architectural differences between the two parts.

The Intel Core Ultra 7 270HX Plus delivers a Cinebench R23 multi-core score of 41913 and a single-core score of 5917. Its Cinebench R20 results show 17603 multi-core and 2485 single-core, while Cinebench R15 shows 4224 multi-core and 596 single-core. These scores place the processor at the 93rd percentile among all CPUs in the database, with an average benchmark score of 61834. The nearest rivals in the database are the Intel Core i9-13900KF with an average score of 61841 (0% delta), the Intel Core i9-13900K at 61766 (0.1% delta), the Intel Core i9-13900T at 61723 (0.2% delta), and the Intel Xeon 636 at 61360 (0.8% delta). The near-identical scores against these desktop-class rivals indicate the Core Ultra 7 270HX Plus performs at the level of a high-end desktop processor from the previous flagship generation.

PassMark results for the Intel processor show a multi-thread score of 48270 and a single-thread score of 4764. The integer math test scores 122449, floating point math scores 163567, and extended instructions score 39283. Data compression scores 493179, data encryption scores 37813, and random string sorting scores 60020. The physics test scores 3843, and the find prime numbers test scores 482. These results demonstrate strong sustained throughput across a variety of workloads, with the floating point and integer math scores indicating substantial compute capability.

The AMD Ryzen Embedded 8645HS has no benchmark entries in the database, so no direct comparison of its measured performance against the Intel part is possible. The database lists its percentile versus all CPUs as 50, which suggests it is positioned at the midpoint of all recorded processors, but this percentile is accompanied by an average benchmark score of 0, indicating the lack of recorded measurements. The Intel part, by contrast, sits at the 93rd percentile with a substantial average score.

The Verdict

The data shows a clear performance hierarchy between these two processors, but the comparison is limited by the missing AMD benchmark results. The Intel Core Ultra 7 270HX Plus is one of the top-performing mobile processors in the database, sitting at the 93rd percentile and matching the average scores of flagship desktop CPUs like the Intel Core i9-13900KF and Core i9-13900K. Its multi-core Cinebench R23 score of 41913 is particularly strong, and its PassMark multi-thread score of 48270 confirms consistent high throughput.

The AMD Ryzen Embedded 8645HS, with no recorded benchmarks, cannot be positioned relative to the Intel part based on measured data. Its 50th percentile ranking suggests it is an average performer among all CPUs in the database, but this ranking is not backed by any test scores. The architectural differences between the two parts provide some context: the Intel processor uses 20 cores and 20 threads, while the AMD uses 6 cores and 12 threads. The Intel part also has a higher boost clock of 5.30 GHz compared to 5.00 GHz, a larger shared L3 cache of 30 MB versus 16 MB, and a higher memory bandwidth of 102.4 GB/s versus 89.6 GB/s.

The AMD processor does have advantages in certain areas. It uses a TSMC 4 nm process node compared to the Intel's 3 nm node, and it supports ECC memory, which the Intel part does not. The AMD part also has a lower TDP of 45 watts versus 55 watts, which may be relevant for thermal-constrained embedded applications. The Intel processor is unlocked, while the AMD is not.

Where Each One Wins

The Intel Core Ultra 7 270HX Plus wins on raw compute performance based on the recorded data. Its 20 cores and 20 threads provide a significant advantage in multi-threaded workloads, as evidenced by the Cinebench R23 multi-core score of 41913 and the PassMark multi-thread score of 48270. The single-core performance is also strong, with a Cinebench R23 single-core score of 5917 and a PassMark single-thread score of 4764. The higher boost clock of 5.30 GHz and the larger 30 MB L3 cache likely contribute to these results. The processor also supports PCIe Gen 5 with 20 lanes, which provides higher bandwidth for modern peripherals and accelerators.

The AMD Ryzen Embedded 8645HS wins on features relevant to embedded and industrial deployments. ECC memory support is a critical feature for reliability-sensitive applications, and the AMD part includes it while the Intel part does not. The lower TDP of 45 watts versus 55 watts may reduce cooling requirements in compact embedded chassis. The AMD part uses DDR5 memory with dual-channel support, the same memory type as the Intel part, but with a lower bandwidth of 89.6 GB/s. The AMD processor integrates a Radeon 760M GPU, while the Intel integrates an Arc Xe-LPG Graphics 64EU, both providing integrated graphics capabilities.

The AMD part has a smaller die size of 178 mm² compared to the Intel's 243 mm², and it uses fewer transistors at 25,000 million versus 17,800 million for the Intel. The higher transistor count on the smaller die suggests a denser design, though the Intel part uses a more advanced 3 nm process node compared to the 4 nm node of the AMD part. The AMD part also has a higher base clock of 4.30 GHz versus 2.40 GHz, which may provide an advantage in lightly threaded workloads where boost clocks are not sustained.

The Intel processor has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. The larger per-core caches and the larger shared L3 on the Intel part provide more data locality capacity.

The transistor and die measurements also differ. The AMD processor contains 25,000 million transistors on a 178 mm² die. The Intel processor contains 17,800 million transistors on a 243 mm² die. The denser AMD design packs more transistors into a smaller area on the older 4 nm node, while the Intel design uses fewer transistors across a larger area on the 3 nm node.

Both processors support DDR5 memory with dual-channel buses, but the Intel part has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s. The AMD part supports ECC memory, a feature absent from the Intel part. The PCIe interfaces also differ: the AMD processor uses Gen 4 with 20 lanes, while the Intel processor uses Gen 5 with 20 lanes.

The sockets are different as well. The AMD Ryzen Embedded 8645HS uses AMD Socket FP8, while the Intel Core Ultra 7 270HX Plus uses Intel BGA 2114. The AMD processor is not multiplier-unlocked, while the Intel processor is multiplier-unlocked. The integrated graphics differ: the AMD part uses a Radeon 760M, and the Intel part uses an Arc Xe-LPG Graphics 64EU.

The release dates are separated by nearly two years. The AMD processor was released on April 1, 2024, while the Intel processor was released on March 16, 2026. Both are marked as Active in production status and target the mobile market segment. The average benchmark score of the Intel processor is 61834, placing it at the 93rd percentile, while the AMD processor has an average benchmark score of 0 and sits at the 50th percentile due to the lack of recorded measurements.
