AMD Ryzen 3 3100U vs AMD Ryzen 5 9500F Comparison

Where Each One Wins

The benchmark data is unambiguous: the AMD Ryzen 5 9500F wins every single recorded test against the AMD Ryzen 3 3100U. Of the 11 head-to-head benchmarks, the Ryzen 5 9500F takes all 11, while the Ryzen 3 3100U records zero wins. This is not a close contest with split victories across different workload types; it is a complete sweep.

The Ryzen 3 3100U does have a position in the database, however. It is a mobile processor with a 15 W TDP, designed for low-power notebooks. Its average benchmark score is 6247, placing it at the 62nd percentile of all CPUs. That percentile indicates it sits above the median processor, but its nearest rivals reveal its true tier: the AMD Ryzen Threadripper 1950X (average score 6231, 0.3% behind), the AMD EPYC 7272 (6186, 1% behind), the Intel Core i9-7940X (6147, 1.6% ahead of the 3100U), and the Intel Core i9-10920X (6347, 1.6% ahead). For a 2-core, 2-thread mobile chip, this level of aggregate performance is respectable, but it is firmly in entry-level territory.

The Ryzen 5 9500F, by contrast, operates in a different performance class entirely. Its average benchmark score is 52873, placing it at the 91st percentile of all CPUs. Its nearest rivals include the AMD Ryzen AI Embedded P164 (52901, 0.1% ahead), the Intel Xeon 634 (52974, 0.2% ahead), the AMD EPYC 7313P (53206, 0.6% ahead), and the AMD Ryzen 9 7900X (53288, 0.8% ahead). The 9500F is within 1% of a Ryzen 9 desktop processor, which indicates its position near the top of the desktop stack.

Use-case analysis follows the score distribution directly. The Ryzen 3 3100U is suited to light mobile workloads where power draw matters more than throughput. The Ryzen 5 9500F is suited to desktop workloads that stress multi-threaded and single-threaded performance alike. There is no recorded benchmark category where the 3100U offers an advantage.

Architecture Differences

The two processors come from different AMD generations and use entirely different underlying designs. The Ryzen 3 3100U belongs to the 3000 series, uses the Picasso codename, and is built on the Zen+ architecture. Its process node is 12 nm, fabricated by GlobalFoundries, with 4,940 million transistors on a 210 mm² die. The Ryzen 5 9500F belongs to the 9000 series, uses the Granite Ridge codename, and is built on the Zen 5 architecture. Its process node is 4 nm, fabricated by TSMC, with 8,315 million transistors on a 70.6 mm² die.

The transistor and die size figures tell a striking story. The 9500F packs 8,315 million transistors into a 70.6 mm² die, while the 3100U spreads 4,940 million transistors across 210 mm². The newer process node allows the 9500F to fit more transistors into less than one-third of the physical area, which directly contributes to its higher clock speeds and lower latency characteristics.

Core and thread counts differ substantially. The 3100U has 2 cores and 2 threads, with a base clock of 1.90 GHz and a boost clock of 3.20 GHz. The 9500F has 6 cores and 12 threads, with a base clock of 3.80 GHz and a boost clock of 5.00 GHz. The 9500F also carries a much higher TDP of 65 W compared to 15 W, reflecting its desktop orientation and greater power envelope.

Cache hierarchies also diverge. The 3100U has 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The 9500F has 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. Although the per-core L1 is smaller on the 9500F, the L2 is double per core and the L3 is eight times larger overall.

Memory support marks a generational split. The 3100U supports DDR4 memory with dual-channel access and a memory bandwidth of 38.4 GB/s. The 9500F supports DDR5 memory with dual-channel access and a memory bandwidth of 89.6 GB/s. The newer platform also enables ECC memory support on the 9500F, while the 3100U does not support ECC.

PCIe capabilities differ as well. The 3100U uses PCIe Gen 3, while the 9500F uses PCIe Gen 5 with 24 lanes available on the CPU. Integrated graphics also separate the two: the 3100U includes Radeon Vega 8 graphics, while the 9500F has no integrated graphics (N/A). The 3100U is a mobile part on AMD Socket FP5, while the 9500F is a desktop part on AMD Socket AM5. The 9500F has an unlocked multiplier; the 3100U does not.

Head-to-Head Benchmarks

The largest percentage gap appears in extended instructions. The 9500F scores 26370 against 2116 for the 3100U, a delta of -92% from the perspective of the 3100U. This test measures the processor's ability to handle specialized instruction sets, and the 9500F's Zen 5 architecture delivers a massive advantage here.

Find prime numbers shows a similar margin. The 9500F scores 220 against 18 for the 3100U, a -91.8% delta. This workload is highly sensitive to integer throughput and clock speed, both of which favor the 9500F. Floating point math follows at -89.7%, with the 9500F scoring 56570 versus 5854. Integer math records -89.5%, with 84198 against 8873.

Data compression and multithread tests both show -88.2% deltas. The 9500F scores 325678 in data compression against 38455, and 28312 in multithread against 3348. Data encryption and physics both show -87.5% deltas: 15716 versus 1972 in encryption, and 1851 versus 232 in physics. Random string sorting closes the gap slightly at -86.3%, with 34174 against 4666.

The narrowest margin appears in single-thread performance. The 9500F scores 4258 against 1592 for the 3100U, a -62.6% delta. This is still a decisive victory, but it is the closest relative contest in the entire suite. The single-thread gap is roughly 2.7 times, while most other tests show gaps of 7 to 12 times. This pattern indicates that the 9500F's advantage grows with multi-threaded and vectorized workloads, while its single-core lead, though large, is comparatively smaller.

Every recorded benchmark confirms the same direction. The 9500F outperforms the 3100U in every category, with deltas ranging from -62.6% to -92%. The aggregate average score difference is even more pronounced: 52873 versus 6247, which places the 9500F at the 91st percentile and the 3100U at the 62nd percentile.

The Verdict

The data supports only one conclusion for raw performance: the AMD Ryzen 5 9500F is the superior processor in every recorded benchmark. It wins all 11 head-to-head tests, with the smallest margin being -62.6% in single-thread performance and the largest being -92% in extended instructions. Its average benchmark score of 52873 is more than eight times that of the 3100U's 6247.

The AMD Ryzen 3 3100U remains a functional mobile processor for low-power applications. Its 15 W TDP, Radeon Vega 8 integrated graphics, and mobile socket designation make it suitable for notebooks where battery life and thermals take priority over compute throughput. Its 62nd percentile ranking shows it is not a weak processor by global standards, but it cannot compete with the 9500F in any measured category.

The AMD Ryzen 5 9500F targets a completely different market. Its 65 W TDP, 6 cores, 12 threads, 32 MB of shared L3 cache, DDR5 support, and PCIe Gen 5 connectivity position it as a high-performance desktop part. Its 91st percentile ranking and proximity to the AMD Ryzen 9 7900X (within 0.8%) confirm its standing. The lack of integrated graphics means a discrete GPU is required, but the performance data indicates that this processor is built for demanding workloads, not casual use.

Buyers should choose based on platform and workload, not on benchmark comparisons, because the two processors are not direct competitors. The 3100U serves the mobile, low-power segment. The 9500F serves the desktop, high-performance segment. In any shared workload, the 9500F wins outright.
