AMD Ryzen 3 3100U vs AMD Ryzen Embedded 9950X3D Comparison

Head-to-Head Benchmarks

The database contains benchmark results for the AMD Ryzen 3 3100U across eleven Passmark tests, while the AMD Ryzen Embedded 9950X3D has no recorded benchmark scores in the database. This asymmetry requires the analysis to rely on the 3100U's measured performance profile and the architectural specifications of both processors.

The Ryzen 3 3100U shows a mixed workload performance picture. In passmark_data_compression, it scores 38,455, which is its strongest result by a wide margin. This score places it in the 62nd percentile of all CPUs in the database. The nearest rivals for the 3100U by average benchmark score include the AMD Ryzen Threadripper 1950X at an average score of 6,231, which is only 0.3% below the 3100U's average of 6,247, and the Intel Core i9-10920X at 6,347, which sits 1.6% higher. The AMD EPYC 7272 trails the 3100U by 1% with an average of 6,186, while the Intel Core i9-7940X scores 6,147, again 1.6% lower.

The 3100U's single-thread performance is recorded at 1,592 in both passmark_single_thread and passmark_singlethread. This relatively modest score reflects the 2-core, 2-thread configuration with a base clock of 1.90 GHz and a boost clock of 3.20 GHz. The integer math workload delivers 8,873, while floating point math reaches 5,854. Extended instructions produce 2,116, and data encryption scores 1,972. The random string sorting test yields 4,666, while the multithread test scores 3,348.

The weakest recorded areas for the 3100U are passmark_find_prime_numbers at 18 and passmark_physics at 232. These low scores align with the processor's limited thread count and modest clock speeds. The average benchmark score for the 3100U is 6,247, which is the figure used for rival comparisons.

The Ryzen Embedded 9950X3D, by contrast, has an average benchmark score of 0 and no nearest rivals listed in the database. This means the head-to-head comparison cannot draw on direct measured performance for the 9950X3D. Instead, the specification gap between the two processors is substantial and worth examining through the available data fields.

The Verdict

The data presents a clear split between the two processors based on measured results and hardware configuration. The Ryzen 3 3100U is the only one of the two with recorded benchmark scores. Its average of 6,247 and 62nd percentile standing indicate it competes with high-end desktop processors from several generations ago, such as the Intel Core i9-10920X and the AMD Ryzen Threadripper 1950X, despite being a 2-core mobile part.

The Ryzen Embedded 9950X3D has no benchmark scores in the database. Its percentile standing is 50, and its average score is 0. This does not mean the processor is slow; it means the database lacks measurement data for this part. The specifications, however, point to a far more powerful processor. With 16 cores and 32 threads, a base clock of 4.30 GHz, and a boost clock of 5.70 GHz, the 9950X3D offers 8 times the core count and 16 times the thread count of the 3100U. The clock advantage is also significant: the 9950X3D's base clock is 2.40 GHz higher than the 3100U's boost clock.

The thermal design power tells a similar story. The 3100U has a TDP of 15 watts, while the 9950X3D has a TDP of 170 watts. That difference of 155 watts indicates the embedded part is designed for sustained high-performance workloads, while the mobile part targets efficiency. The 9950X3D uses DDR5 memory with a recorded bandwidth of 89.6 GB/s, compared to the 3100U's DDR4 at 38.4 GB/s. The 9950X3D also supports ECC memory, which the 3100U does not.

For users choosing between these two parts, the decision comes down to workload requirements. The 3100U suits tasks that need low power consumption and modest compute, as its 15-watt TDP and 2-core design suggest. The 9950X3D targets high-throughput embedded applications, server-adjacent workloads, or desktop-class processing where the 170-watt TDP and 16 cores can be fully utilized. The absence of benchmark data for the 9950X3D means the database cannot confirm its relative standing against other CPUs yet, but the specification sheet indicates a much higher performance ceiling.

Where Each One Wins

The Ryzen 3 3100U wins in power efficiency. Its 15-watt TDP is 155 watts lower than the 9950X3D's 170-watt TDP. This makes it suitable for mobile platforms, as its socket is AMD Socket FP5, a mobile form factor. The 3100U also uses the 12 nm process node from GlobalFoundries, which, while older than the 9950X3D's 4 nm TSMC node, is paired with a much lower power envelope.

The 9950X3D wins in raw compute capacity. Its 16 cores and 32 threads dwarf the 3100U's 2 cores and 2 threads. The 9950X3D's L3 cache is 128 MB, compared to the 3100U's 4 MB shared L3. That is a 32-fold difference in last-level cache. The L2 cache also differs: the 9950X3D has 1 MB per core, while the 3100U has 512 KB per core. The L1 cache is 80 KB per core on the 9950X3D versus 96 KB per core on the 3100U, a rare instance where the older part has more per-core L1.

Memory bandwidth strongly favors the 9950X3D. The recorded bandwidth for the 9950X3D is 89.6 GB/s, which is 2.33 times the 3100U's 38.4 GB/s. Both use dual-channel memory buses, but the 9950X3D's DDR5 support enables the higher bandwidth. The 3100U supports DDR4.

The 9950X3D also wins on PCIe connectivity. It supports PCIe Gen 5 with 24 lanes available from the CPU, while the 3100U supports PCIe Gen 3. The socket difference reinforces the use-case split: the 9950X3D uses AMD Socket AM5, a desktop platform, while the 3100U uses AMD Socket FP5, a mobile platform.

The multiplier is unlocked on the 9950X3D, allowing overclocking, while the 3100U has a locked multiplier. The 9950X3D's integrated graphics are listed as Radeon Graphics, while the 3100U uses Radeon Vega 8. The database does not provide performance scores for either GPU, so no comparison is possible there.

Production status is Active for both processors. The release date for the 9950X3D is recorded as 2025-10-06, while the 3100U has a release date of 2026-05-31. The 3100U is listed as part of the 3000 series with the Picasso codename and Zen+ architecture, while the 9950X3D belongs to the 9000 series with the Granite Ridge codename and Zen 5 architecture.
