AMD Ryzen Embedded 9950X vs Intel Core Ultra 5 250K Plus Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries for the AMD Ryzen Embedded 9950X against the Intel Core Ultra 5 250K Plus. The Intel part, however, has a full set of Cinebench and PassMark scores, while the AMD entry shows an average benchmark score of zero with no individual test results. This means the only measurable performance data in the database belongs to the Intel Core Ultra 5 250K Plus.

The Intel Core Ultra 5 250K Plus posts a Cinebench R23 multi-core score of 30,867 and a single-core score of 2,261. In Cinebench R20, it scores 18,442 multi-core and 2,603 single-core. The older Cinebench R15 test shows 4,640 multi-core and 328 single-core. PassMark results include a multi-thread score of 51,596, a single-thread score of 4,757, integer math at 125,091, floating-point math at 162,692, data compression at 568,721, and data encryption at 42,144. Additional PassMark figures include extended instructions at 44,565, find prime numbers at 486, physics at 3,494, and random string sorting at 69,090.

Without any recorded scores for the AMD Ryzen Embedded 9950X, the database cannot establish a comparative win-loss count between the two. The winsA and winsB fields both sit at zero, reflecting the absence of head-to-head data. The Intel part's average benchmark score of 66,855 places it at the 93rd percentile among all CPUs in the database. Its nearest rivals include the AMD EPYC 4465P with an average score of 66,925 (0.1% higher), the Intel Xeon 6515P at 67,006 (0.2% higher), the Intel Core Ultra 9 275HX at 67,469 (0.9% higher), and the Intel Core Ultra 5 250KF Plus at 66,159 (1.1% lower). The 250K Plus trails the EPYC part by 0.1%, the Xeon by 0.2%, and the Ultra 9 by 0.9%, while leading its KF sibling by 1.1%.

Architecture Differences

The AMD Ryzen Embedded 9950X uses the Granite Ridge codename with Zen 5 architecture from the Ryzen Embedded generation, built on a 4 nm TSMC process. It contains 16 cores and 32 threads, with a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The transistor count is 16,630 million spread across a die size of 2x 70.6 mm². Cache configuration includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. Memory support is DDR5 with a dual-channel bus and 89.6 GB/s bandwidth, plus ECC support. PCIe connectivity uses Gen 5 with 28 lanes from the CPU. Integrated graphics come from Radeon Graphics. The part fits into AMD Socket AM5 and has a TDP of 170 W. The multiplier is unlocked, and the release date is recorded as October 6, 2025.

The Intel Core Ultra 5 250K Plus belongs to the Core Ultra Series 2 with the Arrow Lake Refresh codename, from the Ultra 5 (Arrow Lake) generation. It uses a 3 nm TSMC process and packs 17,800 million transistors on a 243 mm² die. The core layout differs significantly: 18 cores and 18 threads, meaning no simultaneous multithreading. Base clock is 4.20 GHz, boost is 5.30 GHz. Cache amounts to 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Memory support is DDR5 with a dual-channel bus delivering 115.2 GB/s bandwidth, and ECC is supported. PCIe offers Gen 5 with 20 lanes from the CPU. Integrated graphics are Arc Xe-LPG Graphics with 64 execution units. The socket is Intel Socket 1851, TDP is 125 W, and the multiplier is unlocked. Release date is March 10, 2026, and the launch MSRP is $199.

The fundamental architectural split is clear. AMD uses a monolithic chiplet design with two 70.6 mm² dies, while Intel uses a single 243 mm² die. AMD enables simultaneous multithreading, giving 32 threads from 16 cores, whereas Intel runs 18 threads from 18 cores. The process nodes differ by 1 nm, with Intel on the smaller 3 nm node. Cache strategies diverge as well: AMD provides a large 64 MB L3 pool, while Intel offers a smaller 30 MB shared L3 but much larger per-core L1 and L2 allocations. Memory bandwidth favors Intel at 115.2 GB/s versus AMD's 89.6 GB/s, though both support ECC and DDR5.

Where Each One Wins

The Intel Core Ultra 5 250K Plus has all recorded benchmark data, so its strengths are measurable. The Cinebench R23 multi-core score of 30,867 and PassMark multi-thread score of 51,596 indicate a capable multi-core performer. The single-core Cinebench R23 result of 2,261 and PassMark single-thread score of 4,757 show solid per-thread performance. The PassMark data compression score of 568,721 is the highest single metric in the set, suggesting strong throughput in compression workloads. Floating-point math at 162,692 and integer math at 125,091 indicate balanced arithmetic performance. The physics score of 3,494 and random string sorting at 69,090 round out the profile.

The AMD Ryzen Embedded 9950X has no benchmark scores in the database, so no wins can be attributed to it from recorded data. Its architectural specifications, however, point to potential advantages. The 32 threads from 16 cores could favor heavily threaded workloads if the database contained results. The 64 MB L3 cache is larger than Intel's 30 MB, which may benefit cache-sensitive applications. The higher boost clock of 5.70 GHz versus Intel's 5.30 GHz suggests potential single-thread headroom, though no scores confirm this.

The use-case split based on actual data favors the Intel part for every measured workload. For compression, encryption, prime number finding, floating-point math, integer math, physics, and random string sorting, the Intel Core Ultra 5 250K Plus delivers recorded results. The AMD part remains a specification-only entry with no empirical evidence of performance in the database.

The Verdict

The database presents a lopsided comparison. The Intel Core Ultra 5 250K Plus has a full benchmark profile with 17 recorded scores, a 93rd percentile ranking, and an average benchmark score of 66,855. The AMD Ryzen Embedded 9950X has no recorded performance data, an average benchmark score of zero, and a 50th percentile ranking. Any selection between these two based on measured performance must favor the Intel part, as it is the only one with empirical evidence in the database.

The Intel part's Cinebench R23 multi-core score of 30,867 and PassMark multi-thread score of 51,596 demonstrate strong multi-threaded capability. Its nearest rivals all sit within 1.1% of its average score, indicating it performs in a tight competitive cluster. The AMD part's specifications, particularly the 32 threads and 64 MB L3 cache, suggest it could compete in heavy workloads, but no data confirms this.

For builders who require a processor with verified benchmark results, the Intel Core Ultra 5 250K Plus is the only choice supported by the database. Its 125 W TDP is lower than AMD's 170 W, and its 115.2 GB/s memory bandwidth exceeds AMD's 89.6 GB/s. The AMD part offers more threads, a higher boost clock, and a larger L3 cache on paper, but the absence of any recorded scores prevents a data-driven recommendation. The launch MSRP for the Intel part is $199. The verdict from the recorded data is straightforward: the Intel Core Ultra 5 250K Plus delivers measurable performance, while the AMD Ryzen Embedded 9950X remains unverified in this database.
