AMD Ryzen Embedded 9950X vs Intel Core Ultra 9 285HX Comparison

Head-to-Head Benchmarks

The comparison between these two processors is complicated by an asymmetric data set. The AMD Ryzen Embedded 9950X has no recorded benchmark scores in the database, while the Intel Core Ultra 9 285HX carries a full suite of 17 measurements. The recorded data therefore only allows a one-sided analysis of the Intel part's performance, with the AMD part's competitive position derived from architectural comparison and market positioning.

The Intel Core Ultra 9 285HX posts a multithread score of 36,429.5 in Cinebench R23, a result that places it near the top of the mobile processor field. Its single-core score of 2,187.5 in the same test shows strong per-thread performance. In Cinebench R20, the Intel chip scores 20,236 multi-core and 2,856 single-core. The older Cinebench R15 test produces 5,656.5 multi-core and 323.5 single-core. These results confirm consistent scaling across Cinebench generations.

The PassMark suite adds more detail. The Intel part scores 631,885 in data compression, 48,567 in data encryption, and 49,148 in extended instructions. Prime number finding returns 460, floating point math 194,998, integer math 155,076, and random string sorting 77,196. The multithread score is 56,902, with a single-thread score of 4,618. Physics testing yields 3,476. Across the entire measured workload set, the Intel Core Ultra 9 285HX averages 76,155 in the database's benchmark scoring system.

The nearest rivals for the Intel part, all AMD products, bracket it tightly. The AMD Ryzen 9 8945HX averages 76,212, which is 0.1% higher than the Intel part. The AMD EPYC Embedded 8224P averages 76,492, 0.4% higher. The AMD Ryzen Threadripper PRO 9945WX averages 76,513, 0.5% higher. The AMD Ryzen 9 9950X3D averages 75,779, which is 0.5% lower than the Intel chip. These delta percentages show the Intel Core Ultra 9 285HX sitting in a narrow performance band where the closest competitors are separated by less than one percentage point in either direction.

The Intel part's 95th percentile ranking among all CPUs in the database reflects this tight grouping. The AMD Ryzen Embedded 9950X, by contrast, has a 50th percentile ranking with an average benchmark score of zero, indicating the absence of recorded measurements rather than a performance verdict.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen Embedded 9950X uses the Zen 5 architecture, codenamed Granite Ridge, built on a 4 nm process at TSMC. The Intel Core Ultra 9 285HX uses the Arrow Lake architecture, codenamed Arrow Lake-HX, built on a 3 nm process, also at TSMC. Both manufacturers rely on the same foundry, but the process geometry differs by one nanometer.

Core counts diverge sharply. The AMD part has 16 cores and 32 threads, while the Intel part has 24 cores and 24 threads. Intel's chip uses a design without simultaneous multithreading, which explains the equal core and thread counts. AMD enables SMT, giving the Ryzen part a 32-thread count from 16 cores. The base clocks differ, with AMD at 4.30 GHz and Intel at 2.80 GHz. Boost clocks are closer, 5.70 GHz for AMD versus 5.50 GHz for Intel.

Cache hierarchies reflect different strategies. The AMD chip allocates 80 KB of L1 cache per core, 1 MB of L2 per core, and 64 MB of shared L3. The Intel chip uses 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. Intel's per-core cache allocations are larger, but AMD's total L3 pool is larger by 28 MB. Transistor counts are close, with AMD at 16,630 million and Intel at 17,800 million. Die size differs substantially, AMD using two 70.6 mm² dies for a combined 141.2 mm², while Intel uses a single 243 mm² die.

Power and thermal envelopes separate these parts into different product categories. The AMD Ryzen Embedded 9950X carries a 170 W TDP, while the Intel Core Ultra 9 285HX is rated at 55 W. The Intel part's lower TDP aligns with its mobile market segment, while AMD's higher TDP aligns with desktop and embedded use. The AMD chip uses Socket AM5, a socketed desktop platform, while the Intel chip uses BGA 2114, a ball-grid array soldered to the motherboard.

Memory support is identical in type, both using DDR5 with dual-channel buses. Bandwidth differs, with AMD at 89.6 GB/s and Intel at 102.4 GB/s. Both support ECC memory. PCIe connectivity favors AMD, which provides 28 Gen 5 lanes from the CPU, while Intel provides 20 Gen 5 lanes. Integrated graphics differ, AMD using Radeon Graphics and Intel using Arc Xe-LPG Graphics with 64 execution units.

Where Each One Wins

The Intel Core Ultra 9 285HX demonstrates its strengths in the measured benchmarks. Its 24 cores without SMT deliver strong multithread throughput, evidenced by the 36,429.5 Cinebench R23 result and the 56,902 PassMark multithread score. The 5.50 GHz boost clock supports competitive single-thread performance, with the 2,187.5 Cinebench R23 single-core score and 4,618 PassMark single-thread score. The 55 W TDP makes it suitable for high-performance mobile systems where power budgets matter.

The AMD Ryzen Embedded 9950X's advantages are structural rather than measured. Its 32 threads from 16 cores provide more thread-level parallelism than the Intel part's 24 threads. The 64 MB L3 cache doubles as a shared pool, which can benefit workloads with large working sets. The 28 PCIe Gen 5 lanes give it more expansion bandwidth than Intel's 20 lanes. The socketed AM5 design allows for system maintenance and potential processor replacement, unlike Intel's soldered BGA package. The higher 5.70 GHz boost clock gives AMD a nominal peak frequency advantage.

The TDP gap defines different deployment scenarios. Intel's 55 W rating suits thin-and-light high-performance laptops and compact mobile workstations. AMD's 170 W rating indicates a desktop-class part intended for embedded systems, workstations, or other socketed applications where cooling and power delivery can accommodate higher dissipation. The production status of both parts is active, and both have unlocked multipliers.

The database's percentile data places the Intel part at the 95th percentile among all CPUs, a high ranking. The AMD part sits at the 50th percentile, but this reflects the absence of benchmark data rather than measured performance. The nearest rival data for Intel shows the competitive landscape: four AMD processors within 0.5% of the Intel chip's average score. This clustering indicates that the Intel Core Ultra 9 285HX competes directly with top AMD mobile and workstation parts.
