AMD Ryzen Embedded 8645HS vs Intel Core 7 253PE Comparison

AMD Ryzen Embedded 8645HS and Intel Core 7 253PE occupy very different positions in the processor market, one a mobile-focused 6-core part from AMD’s 8000 series, the other a desktop-oriented 10-core processor from Intel’s Bartlett Lake family. The recorded data for the Intel part includes a full set of benchmark scores, while the AMD part has no benchmark entries in the database, so the numerical comparison rests entirely on the Intel measurements and the structural specifications of both chips. What follows is a direct comparison based on the information available in the database, with no speculation beyond the recorded fields.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the AMD Ryzen Embedded 8645HS has no benchmark scores recorded at all. The Intel Core 7 253PE, however, has a substantial set of measurements across Cinebench and Passmark tests, which provides a reference point for what the Intel part delivers. Without AMD scores, the head-to-head comparison is necessarily one-sided, but the Intel numbers can be examined on their own terms and against the Intel part’s nearest rivals.

The Intel Core 7 253PE achieves a Cinebench R23 multicore score of 24880 and a single-core score of 3512. In Cinebench R20, the multicore result is 10449 and the single-core result is 1475. The older Cinebench R15 test shows a multicore score of 2507 and a single-core score of 354. These scores indicate a processor that scales strongly with thread count, as the multicore results are roughly seven times the single-core results in the R20 and R23 tests. The 10 cores and 20 threads of the Intel part, combined with a boost clock of 5.50 GHz, explain this scaling pattern.

Passmark results for the Intel Core 7 253PE show a multithread score of 29271 and a single-thread score of 3955. The integer math score is 114158, floating point math is 80870, and extended instructions score is 21806. Data compression reaches 339133, while data encryption is 18385. Prime number finding scores 138, random string sorting scores 32777, and physics scores 1845. These numbers paint a picture of a processor with strong integer and floating point throughput, with the multithread score sitting at roughly 7.4 times the single-thread score, again reflecting the 10-core, 20-thread configuration.

The nearest rival data for the Intel Core 7 253PE shows an average benchmark score of 40557, placing it at the 87th percentile of all CPUs in the database. The closest competitor is the Intel Core 5 223PE with an average score of 40585, a delta of -0.1%, meaning the Core 7 253PE trails that part by a tenth of a percent. The Intel Core Ultra X7 368H scores 40518, a delta of 0.1%, so the Core 7 253PE leads by a tenth of a percent. The Intel Xeon 6357P scores 40630, a delta of -0.2%, putting the Core 7 253PE two tenths behind. The AMD Ryzen 9 7940H scores 40431, a delta of 0.3%, meaning the Core 7 253PE is three tenths ahead. These deltas are all within a fraction of a percent, so the Core 7 253PE sits in a tight cluster of processors with nearly identical average scores despite very different core counts and architectures.

Where Each One Wins

The Intel Core 7 253PE wins in every measurable benchmark category because it is the only one of the two with recorded scores. Its Cinebench R23 multicore score of 24880 and single-core score of 3512 indicate strong performance in both heavily threaded and lightly threaded workloads. The Passmark multithread score of 29271 and single-thread score of 3955 reinforce this dual strength. For workloads that depend on integer math, the score of 114158 shows solid throughput, while floating point math at 80870 indicates capable numerical processing. Data compression at 339133 is particularly strong, suggesting the processor handles compression workloads well, while data encryption at 18385 is comparatively modest.

The AMD Ryzen Embedded 8645HS has no benchmark data in the database, so there are no recorded wins for that part. However, its specifications suggest where it might excel if measurements existed. The 6-core, 12-thread configuration with a base clock of 4.30 GHz and boost clock of 5.00 GHz on a 4 nm TSMC process would likely offer strong single-thread performance per core, but the lower core count compared to the Intel part suggests it would trail in heavily threaded workloads. The 45 W TDP, versus 65 W for the Intel part, indicates a lower power envelope, which matters for mobile or thermally constrained systems. The AMD part uses DDR5 memory with a dual-channel bus and 89.6 GB/s bandwidth, the same memory bandwidth as the Intel part, so memory throughput would be comparable.

The Intel part is a desktop processor with a 65 W TDP, while the AMD part is a mobile processor with a 45 W TDP. This fundamental difference shapes where each part would win in a real system. The Intel part, with its higher core count and higher boost clock of 5.50 GHz, would likely win in multithreaded desktop workloads like rendering, compilation, and content creation. The AMD part, with its lower TDP and mobile segment designation, would likely win in power-sensitive or space-constrained applications where the 45 W envelope matters more than raw throughput.

Architecture Differences

The two processors differ significantly in architecture. The AMD Ryzen Embedded 8645HS uses Zen 4 architecture under the codename Hawk Point, built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The Intel Core 7 253PE uses Bartlett Lake architecture, built on a 10 nm process at Intel, with no transistor count or die size recorded in the database. The process node difference is substantial: 4 nm versus 10 nm, which typically indicates a density and efficiency advantage for the AMD part, though the Intel part compensates with a higher core count.

Core configurations differ sharply. The AMD part has 6 cores and 12 threads, while the Intel part has 10 cores and 20 threads. The AMD part has a base clock of 4.30 GHz and boost clock of 5.00 GHz, while the Intel part has a base clock of 2.50 GHz and boost clock of 5.50 GHz. The Intel part boosts higher but idles lower, a typical pattern for a desktop processor with more cores and a higher TDP.

Cache hierarchies also differ. The AMD part has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel part has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Intel part has more cache at every level, both per core and in total L3, which supports its higher core count and desktop positioning.

Memory support differs. The AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. Both use a dual-channel memory bus with 89.6 GB/s bandwidth, and both support ECC memory. The Intel part’s support for DDR4 gives it flexibility in system builds, while the AMD part is limited to DDR5.

PCIe support differs. The AMD part uses PCIe Gen 4 with 20 lanes from the CPU, while the Intel part uses PCIe Gen 5 with 16 lanes from the CPU. The Intel part offers newer PCIe generation but fewer lanes, while the AMD part offers more lanes at the older generation.

Integrated graphics differ. The AMD part uses Radeon 760M, while the Intel part uses UHD Graphics 730. The database records no benchmark scores for either integrated GPU, so no performance comparison is possible.

Sockets differ. The AMD part uses AMD Socket FP8, while the Intel part uses Intel Socket 1700. The AMD part is classified as mobile, while the Intel part is classified as desktop. The AMD part was released on 2024-04-01, while the Intel part was released on 2026-03-08, making the Intel part a later release. The Intel part has a recorded launch MSRP of $384, while the AMD part has no launch MSRP recorded.

Neither processor has an unlocked multiplier, so both are locked for overclocking. The Intel part has a part number of SA4QE, while the AMD part has an unknown part number.

The Verdict

The data in the database supports only one direct conclusion: the Intel Core 7 253PE has recorded benchmark scores, and the AMD Ryzen Embedded 8645HS does not. For anyone selecting between these two based on measured performance, the Intel part is the only one with evidence in the database. Its Cinebench R23 multicore score of 24880, Passmark multithread score of 29271, and 87th percentile ranking indicate a capable desktop processor. Its average benchmark score of 40557 places it in a tight cluster with the Intel Core 5 223PE at 40585, Intel Core Ultra X7 368H at 40518, Intel Xeon 6357P at 40630, and AMD Ryzen 9 7940H at 40431, all within 0.3% of each other.

The AMD Ryzen Embedded 8645HS, lacking benchmark data, cannot be evaluated on measured performance. Its specifications show a 6-core, 12-thread Zen 4 part on a 4 nm process with a 45 W TDP, positioned as a mobile processor. The Intel part is a 10-core, 20-thread desktop processor on a 10 nm process with a 65 W TDP. The Intel part has more cores, more threads, a higher boost clock, more cache at every level, and support for both DDR4 and DDR5. The AMD part has a smaller process node, a lower TDP, more PCIe lanes, and a higher base clock.

The choice between these two depends on the application. For a desktop system where multithreaded performance and the full benchmark record matter, the Intel Core 7 253PE is the supported choice. For a mobile or embedded system where the 45 W TDP and smaller process node are priorities, the AMD Ryzen Embedded 8645HS has the relevant specifications, but no measured performance data exists to confirm its capabilities. The database records no wins for either part in a head-to-head comparison, and the AMD part has no scores to compare against the Intel part’s results.
