AMD Ryzen Embedded 9950X vs Intel Core Ultra 5 125UL Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Ryzen Embedded 9950X or the Intel Core Ultra 5 125UL. The head-to-head benchmark table is empty, and neither processor has any entries in its benchmark history. This means there are no measured performance deltas, no percentile comparisons against other CPUs, and no win/loss records to analyze. Both processors sit at the 50th percentile among all CPUs in the database, but this figure is derived from the absence of data, not from actual testing. Without benchmark results, any claim about relative performance in specific workloads would be speculation, not analysis. The only verifiable facts are the architectural and specification differences documented below.

Architecture Differences

The AMD Ryzen Embedded 9950X is built on the Zen 5 architecture with the codename Granite Ridge. It is part of the Ryzen Embedded 9000 series and represents the Zen 5 microarchitecture generation. The processor is fabricated on a 4 nm process at TSMC. The die consists of two separate chiplets, each measuring 70.6 mm², with a combined transistor count of 16,630 million. The cache hierarchy uses 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. There is no 3D V-Cache variant listed. The processor uses the AMD Socket AM5 and has an unlocked multiplier, allowing overclocking.

The Intel Core Ultra 5 125UL is built on the Meteor Lake architecture with the codename Meteor Lake-PS. It is part of the Core Ultra Series 1 and represents the Ultra 5 generation. The processor is fabricated on a 7 nm process at Intel. The cache hierarchy uses 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 MB of shared L3 cache. The processor uses the Intel Socket 1851 and has a locked multiplier, meaning overclocking is not supported. The Intel part's transistor count and die size are not recorded in the database.

The node difference is significant: the AMD part uses a smaller 4 nm process from TSMC, while the Intel part uses a larger 7 nm process from Intel. The cache designs also differ sharply. AMD allocates per-core L1 and L2 caches of 80 KB and 1 MB respectively, with a large 64 MB L3 pool. Intel allocates larger per-core L1 and L2 caches of 112 KB and 2 MB respectively, but only 12 MB of shared L3. This means the AMD processor has over five times the L3 cache capacity. The AMD part's chiplet design with two 70.6 mm² dies contrasts with the Intel part's monolithic approach, though the Intel die size is not recorded.

Specification Differences

The two processors differ across nearly every major specification field. Core count: 16 cores for AMD versus 12 cores for Intel. Thread count: 32 threads for AMD versus 14 threads for Intel. Base clock: 4.30 GHz for AMD versus 1.30 GHz for Intel. Boost clock: 5.70 GHz for AMD versus 4.30 GHz for Intel. TDP: 170 watts for AMD versus 15 watts for Intel.

Socket type: AMD Socket AM5 for the Ryzen Embedded 9950X, Intel Socket 1851 for the Core Ultra 5 125UL. Process node: 4 nm TSMC for AMD versus 7 nm Intel for the Intel part. Foundry: TSMC versus Intel. Transistor count: 16,630 million for AMD, not recorded for Intel. Die size: 2x 70.6 mm² for AMD, not recorded for Intel.

Cache: AMD has 80 KB L1 per core, 1 MB L2 per core, and 64 MB L3. Intel has 112 KB L1 per core, 2 MB L2 per core, and 12 MB L3. Memory support: both use DDR5 dual-channel with 89.6 GB/s bandwidth, but AMD supports ECC memory while Intel does not. PCIe: AMD provides Gen 5 with 28 lanes, Intel provides Gen 4 with 8 lanes. Integrated graphics: AMD uses Radeon Graphics, Intel uses Arc Xe-LPG 64EU.

Market segment: both are desktop processors. Production status: both are active. Release date: AMD was released on 2025-10-06, Intel was released on 2024-04-07. The AMD part has an unlocked multiplier; the Intel part is locked. Part numbers: AMD is 100-000001277E, Intel is SRN96. The Intel part has a launch MSRP of $309, while the AMD part has no recorded launch MSRP.

The Verdict

The data shows two processors with fundamentally different design goals. The AMD Ryzen Embedded 9950X is a high-core-count, high-clock, high-power part designed for throughput. It offers 16 cores and 32 threads, base and boost clocks of 4.30 GHz and 5.70 GHz, and a 170-watt TDP. The Intel Core Ultra 5 125UL is a low-power part with 12 cores and 14 threads, base and boost clocks of 1.30 GHz and 4.30 GHz, and a 15-watt TDP. The TDP difference is dramatic: the AMD part is rated for over eleven times the power of the Intel part.

The AMD processor also leads in memory and I/O capabilities. It supports ECC memory, which the Intel part does not. It provides PCIe Gen 5 with 28 lanes, while the Intel part provides PCIe Gen 4 with 8 lanes. The AMD part has a larger L3 cache at 64 MB versus 12 MB, and it has an unlocked multiplier for overclocking. The Intel part has a locked multiplier and relies on a smaller L3 cache.

The Intel processor counters with a much lower power envelope, a smaller process node advantage is not present (Intel uses 7 nm versus AMD's 4 nm), but it does have a lower launch MSRP of $309. The Intel part also has larger per-core L1 and L2 caches. However, the absence of benchmark data means no performance ranking can be established between the two.

For workloads that demand maximum core count, thread count, clock speed, cache capacity, and PCIe bandwidth, the AMD Ryzen Embedded 9950X is the clear choice based on specifications alone. For applications that prioritize low power consumption, the Intel Core Ultra 5 125UL is the appropriate selection. The choice hinges on whether the workload is power-constrained or performance-constrained, since no measured benchmarks exist to indicate actual performance outcomes.

Where Each One Wins

AMD Ryzen Embedded 9950X wins on:

• Core count: 16 versus 12, a 33% advantage in raw core count.
• Thread count: 32 versus 14, more than double the thread count.
• Base clock: 4.30 GHz versus 1.30 GHz, a 3.00 GHz higher base frequency.
• Boost clock: 5.70 GHz versus 4.30 GHz, a 1.40 GHz higher boost frequency.
• TDP: 170 watts versus 15 watts, indicating a much higher power budget for sustained performance.
• L3 cache: 64 MB versus 12 MB, over five times the shared cache capacity.
• ECC memory support: available on AMD, not on Intel.
• PCIe generation and lanes: Gen 5 with 28 lanes versus Gen 4 with 8 lanes.
• Process node: 4 nm TSMC versus 7 nm Intel, a smaller manufacturing process.
• Multiplier: unlocked versus locked, allowing overclocking on the AMD part.
• Release date: newer, released on 2025-10-06 versus 2024-04-07 for Intel.

Intel Core Ultra 5 125UL wins on:

• TDP: 15 watts versus 170 watts, a far lower power draw.
• L1 cache per core: 112 KB versus 80 KB, a 40% larger per-core L1 cache.
• L2 cache per core: 2 MB versus 1 MB, double the per-core L2 cache.
• Launch MSRP: $309 versus no recorded MSRP for AMD.
• Integrated graphics: Arc Xe-LPG 64EU versus Radeon Graphics, though performance is not benchmarked.
• Socket: Intel Socket 1851 versus AMD Socket AM5, relevant for platform compatibility.
• Release date: earlier, released on 2024-04-07 versus 2025-10-06 for AMD.

The AMD part is positioned for compute-heavy tasks that can exploit many cores, high clocks, large shared cache, and wide PCIe connectivity. The Intel part is positioned for power-sensitive deployments where a 15-watt envelope is mandatory and per-core cache locality matters more than total cache size. Without benchmark results, the practical performance impact of these differences cannot be quantified, but the specification sheet clearly separates the two into distinct usage categories.
