AMD Ryzen Embedded 8645HS vs Intel Core Ultra 9 290HX Plus Comparison

AMD Ryzen Embedded 8645HS vs Intel Core Ultra 9 290HX Plus

Head-to-Head Benchmarks

The benchmark data available for this comparison is one-sided, as the AMD Ryzen Embedded 8645HS has no recorded benchmark scores in the database, while the Intel Core Ultra 9 290HX Plus has a comprehensive set of results. The Intel processor delivers an average benchmark score of 79,574, placing it in the 95th percentile of all CPUs tracked. The AMD chip has a percentile rank of 50, indicating it sits at the median of the database, though this is based on no actual test results. The Intel part’s nearest rivals in the database include the Intel Core i9-14900KF with an average score of 79,371 (0.3% ahead), the AMD EPYC 7413 at 80,041 (0.6% behind), the Intel Core i9-14900K at 79,097 (0.6% ahead), and the Intel Xeon w5-2565X at 80,671 (1.4% behind). This places the Ultra 9 290HX Plus in a tight competitive band around the 79,000 to 80,000 score range.

Looking at the Intel processor’s individual test results, the Cinebench R23 multi-core score of 39,684 is a strong indicator of heavy multi-threaded workload capability. The single-core Cinebench R23 result comes in at 2,356 points. In Cinebench R20, the multi-core score is 21,198 and the single-core score is 2,992. The older Cinebench R15 test shows a multi-core result of 5,981 and a single-core result of 340. PassMark results further characterize the Intel chip: multi-thread performance scores 59,439, single-thread performance scores 4,951, integer math scores 164,839, floating-point math scores 201,773, extended instructions score 51,290, data compression scores 658,724, data encryption scores 50,008, physics scores 3,387, random string sorting scores 80,327, and find prime numbers scores 519. These numbers show a processor that excels in both integer and floating-point operations, with particularly high throughput in data compression tasks.

Since the AMD Ryzen Embedded 8645HS has zero recorded benchmark scores, no direct head-to-head wins can be established from the measurement data. The database shows zero wins for the AMD part and zero wins for the Intel part in the head-to-head comparison field, which is empty. The practical interpretation is that any performance comparison must rely on architectural specifications rather than tested outcomes. The Intel chip’s 95th percentile standing suggests it outperforms the vast majority of CPUs in the database, while the AMD chip’s median percentile rank, without supporting scores, cannot be validated as a performance claim.

FAQ

Q: Does the Intel Core Ultra 9 290HX Plus have a higher single-core score than the AMD Ryzen Embedded 8645HS?

The Verdict

The data clearly favors the Intel Core Ultra 9 290HX Plus for anyone needing proven, high-end performance. It holds a 95th percentile rank among all CPUs, delivers an average benchmark score of 79,574, and its nearest rivals are flagship desktop parts like the Intel Core i9-14900K and i9-14900KF, from which it is essentially within a percentage point. The AMD Ryzen Embedded 8645HS has no benchmark scores in the database, making any performance claim impossible to verify. Its 50th percentile rank is a placeholder rather than a measured result. For workloads that depend on multi-core throughput, the Intel chip’s Cinebench R23 multi-core score of 39,684 and PassMark multi-thread score of 59,439 are substantial numbers. The AMD chip, with 6 cores and 12 threads, cannot match that scale based on specifications alone. The Intel part also offers a higher boost clock of 5.50 GHz versus 5.00 GHz for the AMD, along with a larger shared L3 cache of 36 MB versus 16 MB. The AMD processor does have a higher base clock at 4.30 GHz versus 2.70 GHz, which could favor lightly threaded tasks if it had test data to confirm it, but none exists. The verdict from the recorded data is that the Intel Core Ultra 9 290HX Plus is the only one of the two with measurable performance, and it performs at a level comparable to top-tier desktop CPUs.

Architecture Differences

The AMD Ryzen Embedded 8645HS is built on Zen 4 architecture with the codename Hawk Point, part of the 8000 series and Ryzen Embedded generation. It uses a 4 nm process from TSMC with 25,000 million transistors on a 178 mm² die. Its cache structure includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel Core Ultra 9 290HX Plus uses the Arrow Lake-HX Refresh codename, part of Core Ultra Series 2 and the Ultra 9 (Arrow Lake-HX) generation. It uses a 3 nm process from TSMC with 17,800 million transistors on a 243 mm² die. Its cache structure includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The Intel part’s L1 and L2 caches are larger per core, and its L3 cache is more than double that of the AMD. The Intel chip has an unlocked multiplier, indicating overclocking capability, while the AMD does not. Both processors support DDR5 memory with dual-channel buses and ECC memory. The Intel chip supports PCIe Gen 5, while the AMD supports PCIe Gen 4, both with 20 CPU-only lanes. The integrated graphics differ, with the AMD featuring Radeon 760M and the Intel featuring Arc Xe-LPG Graphics 64EU. The Intel part has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s for the AMD. Both are mobile market segment processors and are currently active in production.

Where Each One Wins

The Intel Core Ultra 9 290HX Plus wins in every category where benchmark data exists. Its multi-core performance is exceptional, as shown by the Cinebench R23 score of 39,684 and PassMark multi-thread score of 59,439. These results indicate strong suitability for rendering, video encoding, scientific computation, and other heavily parallel workloads. The single-core score of 4,951 in PassMark and 2,356 in Cinebench R23 also place it well above typical mobile processors, making it capable for gaming and responsive desktop use. The data compression score of 658,724 and encryption score of 50,008 suggest solid performance in file archiving and security-related tasks. The floating-point math score of 201,773 indicates robust numerical processing ability. The 95th percentile rank places it among the top 5% of all CPUs in the database, a position reinforced by its near parity with the Intel Core i9-14900K and i9-14900KF, both of which are flagship desktop parts.

The AMD Ryzen Embedded 8645HS has no benchmark wins because it has no recorded scores. Its specifications suggest it could be competitive in single-threaded tasks due to its high base clock of 4.30 GHz, which is 60% higher than the Intel’s base clock. The lower TDP of 45 watts versus 55 watts indicates it may fit into more power-constrained designs. The smaller die size of 178 mm² and lower transistor count of 25,000 million could imply lower manufacturing complexity, though the Intel chip has fewer transistors at 17,800 million despite a larger die. The AMD part’s 6 cores and 12 threads are suited for lighter multi-threading, but with only 16 MB of L3 cache versus 36 MB, it would likely lag in cache-heavy workloads. Without test data, the AMD chip’s wins are speculative at best. The database records zero wins for both processors in the head-to-head field, so the only concrete wins belong to the Intel part through its benchmark scores and percentile standing. For any user prioritizing measured performance, the Intel Core Ultra 9 290HX Plus is the clear choice. The AMD Ryzen Embedded 8645HS remains an unverified option, and its median percentile rank should not be mistaken for a tested result.
