AMD Ryzen Embedded 8645HS vs Intel Core i5-14490F Comparison

Where Each One Wins

The benchmark data splits cleanly by workload type. The Intel Core i5-14490F is the clear winner in multi-threaded productivity and compute-heavy tasks. Its Cinebench R23 multicore score of 23000 represents a substantial lead over what the AMD Ryzen Embedded 8645HS would need to match, and the gap is consistent across all multicore tests in the database. The Intel part also dominates in PassMark multithread scoring with 28662, placing it far ahead in rendering, compilation, and parallel workloads.

The AMD Ryzen Embedded 8645HS, by contrast, has no recorded benchmark scores in the database. This makes its performance profile harder to pin down directly. However, the specification data provides a different angle. The AMD part operates at a much higher base clock of 4.30 GHz compared to the Intel's 2.50 GHz, and both reach the same 5.00 GHz boost clock. For workloads that rely heavily on single-thread responsiveness and low-latency instruction execution, the AMD part's higher sustained clock rate should provide a meaningful advantage. The Intel part, despite its lower base clock, compensates with more cores and threads: 10 cores and 16 threads versus 6 cores and 12 threads for the AMD.

The use-case split is therefore straightforward. The Intel Core i5-14490F wins every measured benchmark category that exists in the database. The AMD Ryzen Embedded 8645HS wins on the architectural factors that favor clock speed and power efficiency, particularly in embedded and mobile scenarios where the 45 W TDP versus Intel's 65 W TDP matters for thermal design. The AMD part's integrated Radeon 760M graphics also gives it a functional advantage in systems that need a display output without a discrete GPU, which the Intel part cannot provide since it has no integrated graphics.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 8645HS uses the Zen 4 architecture on the Hawk Point codename, built on TSMC's 4 nm process. The Intel Core i5-14490F uses Raptor Lake architecture with the Raptor Lake-R codename, built on Intel's 10 nm process. This process node difference is significant: the AMD part packs 25,000 million transistors into a 178 mm² die, while the Intel part has no transistor count listed but uses a 215 mm² die. The smaller, denser AMD process allows for higher clock speeds at lower power consumption.

The cache hierarchies differ notably. The AMD part provides 64 KB of L1 cache per core and 1 MB of L2 cache per core, with 16 MB of shared L3 cache. The Intel part provides 80 KB of L1 per core and 1.25 MB of L2 per core, with 24 MB of shared L3 cache. The Intel part's larger L3 cache, combined with its higher core count, gives it a structural advantage in workloads that benefit from large shared pools of fast memory.

Memory support is another key split. The AMD part supports DDR5 only, with dual-channel memory and a measured memory bandwidth of 89.6 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, but has no memory bandwidth figure recorded. This makes the Intel part more flexible for system builders who want to reuse existing DDR4 memory, while the AMD part's narrower memory support is offset by its higher specified bandwidth.

The platform interfaces differ as well. The AMD part uses PCIe Gen 4 with 20 lanes (CPU only), while the Intel part uses PCIe Gen 5 with 16 lanes (CPU only). The Intel part's newer PCIe standard offers higher per-lane bandwidth, though the AMD part provides more total lanes. The AMD part also supports ECC memory, which the Intel part does not, making the AMD part suitable for error-sensitive embedded workloads.

The AMD part includes integrated Radeon 760M graphics, while the Intel part has no integrated graphics at all. This is a decisive architectural difference for systems that need a GPU without an add-in card. The AMD part is classified as a mobile segment processor with an AMD Socket FP8, while the Intel part is a desktop processor with an Intel Socket 1700. Neither has an unlocked multiplier.

Head-to-Head Benchmarks

The database contains recorded benchmark results for the Intel Core i5-14490F across multiple test suites, but no recorded scores for the AMD Ryzen Embedded 8645HS. This asymmetry means the head-to-head comparison relies on the Intel part's absolute scores and the AMD part's specification-derived expectations.

Starting with Cinebench R23, the Intel part scores 23000 in multicore and 3247 in singlecore. The multicore figure is exceptionally strong for a 10-core, 16-thread part and reflects the high sustained boost behavior of Raptor Lake. In Cinebench R20, the Intel part scores 9660 multicore and 1363 singlecore. In the older Cinebench R15, it scores 2318 multicore and 327 singlecore. These numbers show a consistent scaling pattern across the Cinebench generations, with the multicore score dropping proportionally as the test becomes shorter and less memory-bound.

In PassMark testing, the Intel part shows a mixed profile. Its multithread score of 28662 is strong, but the individual sub-tests reveal where it excels. The data compression score of 340026 is notably high, indicating strong performance in compression and decompression workloads. The integer math score of 87844 and floating point math score of 66558 are solid but not exceptional. The extended instructions score of 21731 and data encryption score of 18225 show capable SIMD and encryption throughput. The find prime numbers score of 122 and physics score of 2093 are lower, indicating that these specific workloads do not scale as well with the Intel architecture. The random string sorting score of 35608 is moderate, and the single thread score of 3873 confirms respectable single-core performance.

The AMD part's absence from the benchmark results means no direct score comparison is possible. However, the specification data allows for relative reasoning. The AMD part's 5.00 GHz boost clock matches the Intel part's boost clock exactly. The AMD part's higher base clock of 4.30 GHz versus 2.50 GHz suggests that in single-threaded and lightly threaded tasks, the AMD part should sustain higher average performance. The Intel part's advantage comes from its 10 cores and 16 threads versus 6 cores and 12 threads, giving it a theoretical 66% more cores and 33% more threads.

The Verdict

The recorded data points to a clear choice for most performance-oriented workloads: the Intel Core i5-14490F delivers substantially higher multi-threaded performance, as demonstrated by its Cinebench R23 multicore score of 23000 and PassMark multithread score of 28662. Its 10-core, 16-thread configuration, combined with 24 MB of shared L3 cache, gives it a structural advantage in rendering, compilation, and parallel processing. Its percentile ranking of 86 among all CPUs, versus the AMD part's 50, confirms this positioning.

The AMD Ryzen Embedded 8645HS is the better choice for embedded and mobile applications where power efficiency and integrated graphics matter. Its 45 W TDP versus the Intel part's 65 W TDP makes it easier to cool in compact chassis. The Radeon 760M integrated GPU removes the need for a discrete graphics card in basic display and media workloads. The ECC memory support is a practical feature for reliability-sensitive embedded systems. The higher base clock of 4.30 GHz should provide snappy single-threaded performance in less demanding tasks.

The Intel part's lack of integrated graphics is a significant limitation for systems that cannot accommodate a discrete GPU. The AMD part's lack of recorded benchmark scores makes its absolute performance uncertain, but the architectural data suggests it trades multi-core throughput for efficiency and integration. For a desktop system with a discrete GPU where raw compute is the priority, the Intel Core i5-14490F is the stronger option. For a compact, power-conscious embedded system that needs graphics output and ECC support, the AMD Ryzen Embedded 8645HS is the appropriate selection. The two processors serve different markets, and the data supports each for its intended use case.
