Architecture Differences

The two processors belong to entirely different generations and design philosophies. The AMD Ryzen 3 3100U is a mobile part from the 3000 series, built on the Zen+ architecture with the Picasso codename. It uses a 12 nm process manufactured by GlobalFoundries, with a die size of 210 mm² and 4,940 million transistors. The chip is designed for low-power mobile workloads, as evidenced by its 15 watt TDP and its socket, AMD Socket FP5. Its integrated graphics are Radeon Vega 8, and it supports PCIe Gen 3.

The AMD Ryzen Embedded 9950X, in contrast, is a desktop-class processor from the 9000 series, built on the Zen 5 architecture with the Granite Ridge codename. It uses a much more advanced 4 nm process from TSMC, with a dual-die design comprising 2x 70.6 mm² and a total of 16,630 million transistors. This chip has a 170 watt TDP and uses AMD Socket AM5. Its integrated graphics are listed simply as Radeon Graphics, and it supports PCIe Gen 5 with 28 lanes from the CPU only.

The cache hierarchies differ substantially. The Ryzen 3 3100U has 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Ryzen Embedded 9950X has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and a much larger 64 MB of L3 cache. The larger L3 cache on the Embedded part is a critical advantage for workloads that repeatedly access large datasets.

Memory support also diverges. The Ryzen 3 3100U uses DDR4 with a memory bandwidth of 38.4 GB/s and no ECC support. The Ryzen Embedded 9950X uses DDR5 with a memory bandwidth of 89.6 GB/s and supports ECC memory. The Embedded chip also has an unlocked multiplier, while the mobile chip does not. The production status for both is listed as Active, though the release dates differ, with the Ryzen 3 3100U released later in the database records.

Head-to-Head Benchmarks

The database contains benchmark results for the Ryzen 3 3100U across multiple PassMark tests, but the Ryzen Embedded 9950X has no recorded benchmark scores in the current dataset. This makes a direct numerical comparison impossible for most tests. However, the available data for the Ryzen 3 3100U can be examined on its own terms.

The Ryzen 3 3100U scores 38,455 in PassMark data compression, which is by far its highest single-test result. In data encryption, it scores 1,972. Extended instructions yield a score of 2,116. The find prime numbers test shows a score of 18, which is a low figure reflecting the limited core count. Floating point math produces a score of 5,854, while integer math scores 8,873. The multithread score is 3,348, and the physics test gives a score of 232. Random string sorting yields 4,666. The single-thread score is 1,592, recorded identically in both single-thread test entries.

Its average benchmark score is 6,247, and it sits at the 62nd percentile among all CPUs in the database. The nearest rivals in the database include the AMD Ryzen Threadripper 1950X, which has an average score of 6,231, putting the Ryzen 3 3100U 0.3% ahead. The AMD EPYC 7272 scores 6,186, with the Ryzen 3 3100U 1% ahead. The Intel Core i9-10920X scores 6,347, placing the Ryzen 3 3100U 1.6% behind. The Intel Core i9-7940X scores 6,147, with the Ryzen 3 3100U 1.6% ahead.

These delta percentages are narrow, indicating that the Ryzen 3 3100U, despite having only 2 cores, lands in a competitive average score band against high-core-count desktop and server parts. The lack of benchmark data for the Ryzen Embedded 9950X means the database currently shows zero wins for either side in head-to-head comparisons, as no matching tests are recorded.

Where Each One Wins

The Ryzen 3 3100U wins in scenarios where power consumption and physical footprint are the primary constraints. Its 15 watt TDP is a fraction of the 170 watt TDP of the Ryzen Embedded 9950X. For mobile devices, thin-and-light laptops, or fanless embedded systems, the Ryzen 3 3100U offers a complete package with integrated Radeon Vega 8 graphics, eliminating the need for a discrete GPU. Its 62nd percentile ranking versus all CPUs in the database, combined with an average benchmark score of 6,247, shows that it holds its own against much larger desktop and server processors in aggregate scoring, even with only 2 cores.

The Ryzen 3 3100U also wins on compatibility with older memory standards. Its DDR4 support and PCIe Gen 3 interface make it suitable for systems using mature, widely available components. The database shows it is within 1.6% of the Intel Core i9-10920X and ahead of the AMD EPYC 7272, the Intel Core i9-7940X, and the AMD Ryzen Threadripper 1950X in average benchmark score, which is a notable result for a 2-core mobile chip.

The Ryzen Embedded 9950X wins in raw computational capacity. Its 16 cores and 32 threads, combined with a 5.70 GHz boost clock, position it for heavy multi-threaded workloads. The 64 MB of L3 cache is a major advantage for data-intensive applications. The support for DDR5 memory with 89.6 GB/s bandwidth more than doubles the memory throughput of the Ryzen 3 3100U. ECC memory support makes it suitable for reliability-critical environments. The unlocked multiplier allows tuning for specific performance targets, and the PCIe Gen 5 support with 28 CPU lanes provides high-bandwidth connectivity for modern accelerators and storage devices.

The Ryzen Embedded 9950X also wins on process technology. The 4 nm node from TSMC represents a significant generational leap over the 12 nm node used by the Ryzen 3 3100U, which translates into higher clock speeds and better transistor density. The 16,630 million transistors in the Embedded chip dwarf the 4,940 million in the mobile part.

The Verdict

The data in the database points to two very different use cases. The AMD Ryzen 3 3100U is a low-power mobile processor with a 15 watt TDP, 2 cores, and 2 threads. Its average benchmark score of 6,247 places it in the 62nd percentile, and it edges out several high-end desktop and server chips in average score, including the AMD Ryzen Threadripper 1950X, the AMD EPYC 7272, and the Intel Core i9-7940X. It uses DDR4 memory, lacks ECC support, and has integrated Radeon Vega 8 graphics. This chip is appropriate for compact, power-sensitive systems where the integrated GPU and low thermal envelope are decisive factors.

The AMD Ryzen Embedded 9950X is a high-performance desktop processor with 16 cores, 32 threads, a 170 watt TDP, and a 5.70 GHz boost clock. It uses DDR5 memory with ECC support, has 64 MB of L3 cache, and supports PCIe Gen 5. The database currently has no benchmark scores for this chip, so direct performance comparisons cannot be quantified. However, its specification sheet shows a clear intent for demanding workloads that require substantial multi-threading, large caches, and high memory bandwidth.

The choice between the two depends on the workload profile. For mobile computing, low-power embedded systems, or any application where power draw is a hard limit, the Ryzen 3 3100U is the only viable option between the two, given its 15 watt TDP. For server-class or high-end desktop tasks that can absorb 170 watts of power draw, the Ryzen Embedded 9950X offers far more cores, threads, cache, and memory bandwidth. The absence of benchmark data for the Embedded chip means its real-world performance cannot be verified from the database, but the architectural advantages are clear from the specifications. The Ryzen 3 3100U is a capable low-power part, while the Ryzen Embedded 9950X is designed for maximum throughput in a desktop form factor. Both are listed as Active in production status, and both have release dates recorded in the database, but their intended markets could not be more different.
