Architecture Differences

The AMD Ryzen Embedded 9950X belongs to the 9000 series and carries the codename Granite Ridge, based on the Zen 5 microarchitecture. The Intel Core Ultra 9 290HX Plus is part of the Core Ultra Series 2, codenamed Arrow Lake-HX Refresh, and belongs to the Ultra 9 generation. These are fundamentally different designs targeting different platforms and usage models.

The fabrication processes differ significantly. AMD uses a 4 nm node from TSMC, while Intel uses a 3 nm node, also from TSMC. The transistor counts are close but slightly favor Intel: 16,630 million for AMD versus 17,800 million for Intel. The die size tells a different story. AMD uses a chiplet design with 2x 70.6 mm² dies, totaling roughly 141.2 mm² across two chiplets, while Intel uses a monolithic 243 mm² die.

Cache hierarchies are structured differently. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and a shared 64 MB L3 cache. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and a shared 36 MB L3 cache. The per-core cache allocations are larger on Intel, but AMD's total L3 pool is substantially larger at 64 MB versus 36 MB.

PCIe lane counts also differ. The AMD processor provides Gen 5 with 28 lanes from the CPU only, while the Intel processor provides Gen 5 with 20 lanes from the CPU only. This gives AMD more direct expansion capacity for high-bandwidth devices.

The socket and form factor differences are central to their positioning. AMD uses Socket AM5, a desktop socket, while Intel uses BGA 2114, a soldered mobile package. The TDP ratings diverge sharply: AMD is rated at 170 W, while Intel is rated at 55 W. Both have unlocked multipliers, though the Intel part's mobile BGA packaging limits practical overclocking compared to the desktop AMD socket.

Where Each One Wins

The Intel Core Ultra 9 290HX Plus is the clear winner in the recorded benchmark data, holding 17 benchmark scores to AMD's zero, since the AMD part has no recorded benchmark entries in the database. Intel's processor achieves a 95th percentile ranking among all CPUs, while the AMD Ryzen Embedded 9950X sits at the 50th percentile with an average benchmark score of zero due to missing data.

In the absence of measured AMD results, the Intel part's strengths can be characterized through its nearest rival comparisons. The Core Ultra 9 290HX Plus posts an average benchmark score of 79,574, placing it 0.3% ahead of the Intel Core i9-14900KF, 0.6% ahead of the Intel Core i9-14900K, and trailing the AMD EPYC 7413 by 0.6% and the Intel Xeon w5-2565X by 1.4%. These tight margins indicate that the 290HX Plus competes at the top of the desktop and workstation performance tiers.

The AMD Ryzen Embedded 9950X's architectural advantages, such as its higher boost clock and larger L3 cache, remain theoretical in the database because no benchmark scores are recorded for it. The data therefore supports the Intel part as the measured performance leader, with the AMD part's actual capabilities unquantified in our measurements.

Specification Differences

The two processors differ across nearly every major specification category. The AMD Ryzen Embedded 9950X uses 16 cores and 32 threads, while the Intel Core Ultra 9 290HX Plus uses 24 cores and 24 threads. Base clocks are 4.30 GHz for AMD and 2.70 GHz for Intel. Boost clocks are 5.70 GHz for AMD and 5.50 GHz for Intel.

TDP is a major differentiator: 170 W for AMD versus 55 W for Intel. Socket types are incompatible: AMD Socket AM5 versus Intel BGA 2114. Process nodes differ: 4 nm for AMD versus 3 nm for Intel. Transistor counts are 16,630 million for AMD and 17,800 million for Intel. Die sizes are 2x 70.6 mm² for AMD and 243 mm² for Intel.

Cache configurations differ completely. AMD has 80 KB L1 per core, 1 MB L2 per core, and 64 MB L3. Intel has 192 KB L1 per core, 3 MB L2 per core, and 36 MB L3. Memory bandwidth is 89.6 GB/s for AMD and 102.4 GB/s for Intel. PCIe lanes are 28 for AMD and 20 for Intel, both Gen 5.

Integrated graphics differ: AMD uses Radeon Graphics, Intel uses Arc Xe-LPG Graphics 64EU. Market segments are Desktop for AMD and Mobile for Intel. Release dates are approximately five months apart: AMD released in October 2025, Intel in March 2026. Both support DDR5, dual-channel memory, and ECC memory. Both have unlocked multipliers.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the AMD Ryzen Embedded 9950X and the Intel Core Ultra 9 290HX Plus, and no benchmark scores are recorded for the AMD processor. The Intel part, however, has a full suite of 17 benchmark scores across Cinebench and Passmark tests.

In Cinebench R15, the Intel Core Ultra 9 290HX Plus scores 5,981 in multicore and 340 in singlecore. In Cinebench R20, it scores 21,198 multicore and 2,992 singlecore. In Cinebench R23, it scores 39,684 multicore and 2,356 singlecore. These results show strong scaling in heavily threaded workloads, with the multicore scores far outpacing the singlecore figures.

Passmark results for the Intel processor cover a range of workload types. The multithread score is 59,439, while the single-thread score is 4,951. Integer math scores 164,839, floating-point math scores 201,773, and extended instructions score 51,290. Data compression scores 658,724, data encryption scores 50,008, and random string sorting scores 80,327. Physics scores 3,387, and prime number finding scores 519.

The Intel part's average benchmark score of 79,574 places it in the 95th percentile of all CPUs. Its nearest rivals are tightly clustered: the Intel Core i9-14900KF at 79,371 (0.3% behind), the AMD EPYC 7413 at 80,041 (0.6% ahead), the Intel Core i9-14900K at 79,097 (0.6% behind), and the Intel Xeon w5-2565X at 80,671 (1.4% ahead). This clustering indicates that the 290HX Plus sits within roughly 1.5% of four high-end competitors in either direction.

Because the AMD Ryzen Embedded 9950X has no recorded benchmark scores, no direct quantitative comparison is possible from the database. The Intel part's scores stand as the only measured performance data available for this comparison. The AMD processor's higher boost clock, larger L3 cache, and higher TDP suggest it may perform competitively, but the database does not contain measurements to confirm or refute that expectation.
