AMD Ryzen 3 3100U vs Intel Core i5-14600T Comparison

The AMD Ryzen 3 3100U and the Intel Core i5-14600T occupy entirely different tiers of the processor market, and the benchmark data confirms a decisive performance gap. The Intel part wins 11 of 11 recorded head-to-head comparisons, with the AMD processor trailing by margins ranging from 57.5% to 91% depending on the workload. The average benchmark score for the Ryzen 3 3100U is 6,247, placing it at the 62nd percentile of all CPUs, while the Core i5-14600T averages 32,707, good for the 83rd percentile. These are not close competitors; they are processors designed for different classes of systems with vastly different performance ceilings.

Head-to-Head Benchmarks

The most lopsided result in the head-to-head set is floating point math, where the Intel Core i5-14600T scores 64,726 against the Ryzen 3 3100U's 5,854, a delta of 91%. This indicates the Intel part processes floating-point workloads at nearly eleven times the rate of the AMD chip. Integer math shows a similar pattern: Intel scores 95,112 versus AMD's 8,873, a 90.7% difference. These two results alone establish that the i5-14600T is in a different computational class for number-crunching tasks.

Data encryption is another area of massive disparity. The Intel processor records 18,226 points, while the AMD Ryzen 3 3100U manages only 1,972, a delta of 89.2%. The extended instructions test follows at 16,985 versus 2,116, an 87.5% gap. The physics test shows Intel at 1,873 versus AMD's 232, an 87.6% difference. Data compression results are similarly one-sided: Intel scores 301,827, AMD scores 38,455, a delta of 87.3%.

The multithreaded PassMark score, often a strong indicator of overall throughput, favors Intel at 26,409 versus AMD's 3,348, an 87.3% gap. Random string sorting shows Intel at 34,310 and AMD at 4,666, a delta of 86.4%. Prime number finding is less extreme but still heavily Intel-favored: 121 versus 18, an 85.1% gap.

The narrowest margin comes in single-thread performance, where the Intel Core i5-14600T scores 3,744 against the Ryzen 3 3100U's 1,592, a delta of 57.5%. While still a substantial advantage, this is the closest the AMD part comes to its rival in any measured category. The single-thread result suggests that clock speed and per-core efficiency differences, while significant, are not as overwhelming as the core-count-driven multithreaded gaps.

Architecture Differences

The two processors diverge fundamentally in their underlying designs. The AMD Ryzen 3 3100U is a 2-core, 2-thread mobile processor based on the Picasso codename, part of the Zen+ generation, fabricated on a 12 nm process at GlobalFoundries. It uses the AMD Socket FP5 and carries a 15 W TDP. Its cache configuration includes 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The transistor count is listed at 4,940 million on a 210 mm² die.

The Intel Core i5-14600T is a 14-core, 20-thread desktop processor using the Raptor Lake architecture with the Raptor Lake-R codename, part of the Core 14th Gen series. It is built on a 10 nm process at Intel, with a die size of 257 mm². It uses Intel Socket 1700 and has a 35 W TDP. Cache amounts are larger per core: 80 KB of L1, 2 MB of L2, and 24 MB of shared L3. The Intel part supports both DDR4 and DDR5 memory, while the AMD part is limited to DDR4. Intel also enables ECC memory, which the AMD chip does not support.

PCIe capabilities differ sharply. The Intel Core i5-14600T provides Gen 5 with 16 lanes from the CPU, while the AMD Ryzen 3 3100U is limited to Gen 3. Integrated graphics also differ: AMD uses Radeon Vega 8, Intel uses UHD Graphics 770. The market segments reflect their intended use: the AMD chip is marked as Mobile, the Intel chip as Desktop. The release dates are also far apart, with Intel shipping in January 2024 and AMD listed with a later release date. The Intel part carries a launch MSRP of $255.

Specification Differences

The two processors differ across nearly every major specification field. Core count is 2 for the AMD part versus 14 for Intel. Threads are 2 versus 20. Base clocks are close, with AMD at 1.90 GHz and Intel at 1.80 GHz, but boost clocks diverge sharply: 3.20 GHz for AMD, 5.10 GHz for Intel. TDP is 15 W versus 35 W.

Sockets are incompatible: AMD Socket FP5 versus Intel Socket 1700. The process nodes differ, with AMD at 12 nm and Intel at 10 nm. Foundries are different, with GlobalFoundries producing the AMD chip and Intel producing its own. Die sizes are 210 mm² for AMD and 257 mm² for Intel. Cache structures vary in size and organization, with Intel's L2 at 2 MB per core versus AMD's 512 KB per core, and L3 at 24 MB shared versus 4 MB shared.

Memory support differs in breadth, with Intel accepting both DDR4 and DDR5 while AMD accepts only DDR4. Memory bus is dual-channel for both, but memory bandwidth is listed only for AMD at 38.4 GB/s. ECC memory is supported by Intel, not by AMD. PCIe generations differ, with Intel at Gen 5 and AMD at Gen 3. Integrated graphics are different models: Radeon Vega 8 versus UHD Graphics 770. Market segments are Mobile versus Desktop. The Intel part has a launch MSRP of $255; the AMD part has no listed launch MSRP.

Where Each One Wins

The Intel Core i5-14600T wins every recorded benchmark comparison. Its advantages are largest in floating-point math, integer math, and data encryption, where it leads by roughly 90% or more. It also dominates in multithreaded workloads, physics simulations, and data compression, with margins near 87%. The smallest win is in single-thread performance, where it still leads by 57.5%. The 14-core, 20-thread configuration with a 5.10 GHz boost clock and 24 MB of L3 cache drives these results.

The AMD Ryzen 3 3100U has no benchmark wins in the head-to-head set, but its low 15 W TDP and mobile market segment position it for a different role. Its 2-core, 2-thread design with a 3.20 GHz boost clock and 4 MB of L3 cache suits lightweight, power-constrained systems. The data shows it is competitive within its own percentile class, sitting at the 62nd percentile versus the Intel part's 83rd percentile, but it does not offer a performance advantage in any measured category against this particular rival. For workloads that fit within its modest capabilities, it remains an active production part, but the recorded benchmarks indicate the Intel Core i5-14600T is the stronger processor across all tested metrics.
