AMD Ryzen 3 3100U vs Intel Core i9-14900 Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep in the head-to-head benchmark suite. The Intel Core i9-14900 wins all 11 recorded comparisons, with the AMD Ryzen 3 3100U trailing by margins that range from substantial to overwhelming. The smallest gap appears in the single-threaded tests, where the Ryzen 3 3100U scores 1592 against the i9-14900's 4323, a delta of 63.2% in Intel's favor. That is still a commanding lead, but it represents the closest the AMD part comes to its rival in any direct comparison.

The largest deltas emerge in heavily parallel workloads. In floating-point math, the i9-14900 posts 120262 against 5854, a 95.1% advantage. Integer math shows a similar pattern: 175010 versus 8873, a 94.9% gap. Data encryption favors Intel by 94.1%, with scores of 33540 and 1972 respectively. Extended instructions follow at 93.1% (30624 versus 2116), and data compression sits at 93% (550271 versus 38455). These results indicate that the i9-14900's additional cores and threads translate into massive throughput advantages wherever the workload can scale.

The multithreaded PassMark score reinforces this pattern. Intel reaches 44578, while AMD manages 3348, a 92.5% deficit. Prime number finding shows a 90.4% gap (188 versus 18), physics simulation a 90.7% gap (2486 versus 232), and random string sorting a 92.4% gap (61060 versus 4666). The Ryzen 3 3100U has no recorded wins in any category, so the head-to-head data presents a one-sided picture.

Context from the broader benchmark database confirms the scale of the separation. The Ryzen 3 3100U sits at the 62nd percentile of all CPUs, with an average benchmark score of 6247. Its nearest rivals include the AMD Ryzen Threadripper 1950X (6231, 0.3% behind), the AMD EPYC 7272 (6186, 1% behind), and the Intel Core i9-7940X (6147, 1.6% behind). The Intel Core i9-14900, by contrast, occupies the 92nd percentile with an average score of 58115. Its nearest rivals are the Intel Xeon Platinum 8260M (58323, 0.4% ahead), the AMD Ryzen 7 9850X3D (58386, 0.5% ahead), and the Intel Xeon w5-2545 (58504, 0.7% ahead). In other words, the i9-14900 competes at the top end of the database, while the Ryzen 3 3100U sits in the mid-range.

The single-thread comparison deserves extra attention, since it is the only test where the Ryzen 3 3100U comes within a factor of roughly 2.7. Even there, the Intel part's 4323 score is more than double the AMD part's 1592. The i9-14900 also records additional benchmark results outside the head-to-head set, including Cinebench R15 multicore (4793), R15 singlecore (315), R20 multicore (15910), R20 singlecore (2245), R23 multicore (31070), R23 singlecore (2212), Geekbench multicore (18495), and Geekbench singlecore (2488). These figures are not available for the Ryzen 3 3100U in the database, so no direct comparison is possible for those tests.

Architecture Differences

The two processors come from different design eras and target entirely different market segments. The AMD Ryzen 3 3100U uses the Picasso architecture, based on the Zen+ microarchitecture, and is built on a 12 nm process at GlobalFoundries. It is a mobile part with 2 cores and 2 threads, a base clock of 1.90 GHz, and a boost clock of 3.20 GHz. The Intel Core i9-14900 uses Raptor Lake-R, a refresh of the Raptor Lake architecture, built on a 10 nm process at Intel. It is a desktop part with 24 cores and 32 threads, a base clock of 2.00 GHz, and a boost clock of 5.80 GHz.

The transistor counts differ sharply. The Ryzen 3 3100U integrates 4,940 million transistors on a 210 mm² die. The i9-14900 has no transistor count recorded in the database, but its die size is 257 mm². Cache configurations also diverge. The AMD part offers 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel part offers 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The L3 difference is particularly relevant for workloads that rely on large working sets, since the i9-14900 holds nine times the shared cache.

Memory support separates the two as well. The Ryzen 3 3100U supports DDR4 only, with a dual-channel memory bus and a recorded bandwidth of 38.4 GB/s. The i9-14900 supports both DDR4 and DDR5, also on a dual-channel bus, though no bandwidth figure is recorded for it. ECC memory is supported on the Intel part but not on the AMD part. PCIe capabilities differ: the Ryzen 3 3100U uses PCIe Gen 3, while the i9-14900 uses PCIe Gen 5 with 16 CPU lanes.

Integrated graphics also differ. The AMD part carries Radeon Vega 8, while the Intel part carries UHD Graphics 770. The AMD part is not multiplier unlocked, and neither is the Intel part. The Ryzen 3 3100U uses AMD Socket FP5, while the i9-14900 uses Intel Socket 1700.

Where Each One Wins

Given the head-to-head sweep, the Intel Core i9-14900 wins every recorded benchmark category. The data shows no workload in the comparison set where the Ryzen 3 3100U takes the lead. The Intel part's advantages are largest in floating-point math (95.1%), integer math (94.9%), and data encryption (94.1%), which suggests it is the stronger choice for compute-heavy, parallel, and cryptographic workloads. The multithreaded PassMark score (44578 versus 3348) reinforces that the i9-14900 is built for throughput.

The Ryzen 3 3100U, despite losing every head-to-head test, still has a role in the database as a low-power mobile processor. Its 15 W TDP, against the i9-14900's 65 W TDP, indicates a far lower power envelope. The database does not record a TDP for the i9-14900 that matches the Ryzen's mobile-class figure, so any power comparison must rely on the stated numbers. The Ryzen 3 3100U also uses a smaller die (210 mm² versus 257 mm²) and a smaller process node in name (12 nm versus 10 nm), though the transistor density story is incomplete because the Intel part lacks a recorded transistor count.

For single-threaded tasks, the i9-14900 still wins by 63.2%, but that is the closest margin in the entire suite. The Ryzen 3 3100U's single-thread score of 1592 places it in the same performance class as much older desktop parts, as its nearest rivals show. The i9-14900's single-thread score of 4323 puts it among the top of the database's desktop processors.

The specification differences point to separate use cases. The Ryzen 3 3100U is a mobile processor with integrated Radeon Vega 8 graphics, DDR4 support, and a 15 W TDP. The i9-14900 is a desktop processor with 24 cores, 32 threads, DDR4/DDR5 support, ECC memory support, PCIe Gen 5, and a 65 W TDP. The benchmark data confirms that the i9-14900 is in a different performance tier entirely.

Specification Differences

The two processors differ in nearly every recorded specification. The Ryzen 3 3100U has 2 cores and 2 threads, while the i9-14900 has 24 cores and 32 threads. Base clocks are 1.90 GHz versus 2.00 GHz, and boost clocks are 3.20 GHz versus 5.80 GHz. TDP is 15 W versus 65 W. Sockets are AMD Socket FP5 versus Intel Socket 1700. The AMD part is from the 3000 series, while the Intel part is from Core 14th Gen.

The process nodes differ: 12 nm at GlobalFoundries for the AMD part, 10 nm at Intel for the Intel part. The AMD part has a recorded transistor count of 4,940 million and a die size of 210 mm². The Intel part has no transistor count but a die size of 257 mm². Cache configurations differ per core and in total shared L3: 96 KB L1 per core, 512 KB L2 per core, 4 MB L3 shared for the AMD part; 80 KB L1 per core, 2 MB L2 per core, 36 MB L3 shared for the Intel part.

Memory support differs: the AMD part supports DDR4 only, while the Intel part supports DDR4 and DDR5. The AMD part has a recorded memory bandwidth of 38.4 GB/s; the Intel part has none recorded. ECC memory is false for the AMD part and true for the Intel part. PCIe is Gen 3 for the AMD part and Gen 5 with 16 CPU lanes for the Intel part. Integrated graphics are Radeon Vega 8 versus UHD Graphics 770. Market segments are Mobile versus Desktop. Release dates are 2026-05-31 for the AMD part and 2024-01-07 for the Intel part. The Intel part has a launch MSRP of $549. The AMD part has no launch MSRP recorded. Part numbers are YM3100C4T2OFG for the AMD part and SRN3V for the Intel part.
