Architecture Differences

The two processors come from different architectural generations and design philosophies. The AMD Ryzen 3 3100U is built on the Picasso architecture, which is based on Zen+ and manufactured on a 12 nm process at GlobalFoundries. It uses 4,940 million transistors across a 210 mm² die. The Intel Core i3-14100T uses Raptor Lake Refresh architecture, manufactured on a 10 nm process at Intel, with a die size of 163 mm². The Intel part does not list a transistor count in the database.

Core organization differs substantially. The AMD part is a dual-core design with no simultaneous multithreading, yielding 2 threads total. The Intel part is a quad-core design with hyperthreading support, yielding 8 threads total. This is the primary driver of the multithreaded performance gap. The Intel processor also has a significantly larger L3 cache: 12 MB shared versus 4 MB shared on AMD. L2 cache per core is also larger on Intel at 1.25 MB versus 512 KB, though AMD has more L1 per core at 96 KB versus 80 KB.

Memory support also diverges. The AMD Ryzen 3 3100U supports DDR4 only, with dual-channel memory and a measured bandwidth of 38.4 GB/s. The Intel Core i3-14100T supports both DDR4 and DDR5, also dual-channel, though no bandwidth figure is recorded in the database. PCIe connectivity differs as well: AMD uses Gen 3, while Intel uses Gen 5 with 16 lanes for the CPU.

The integrated graphics solutions are from different vendors and generations. AMD pairs the CPU with Radeon Vega 8, while Intel uses UHD Graphics 730. The process node difference (12 nm versus 10 nm) and the transistor density contribute to the Intel part's higher clock ceilings, but the database does not include direct power efficiency comparisons.

Specification Differences

The specification table shows clear separation between the two parts. The AMD Ryzen 3 3100U is a mobile processor from the 3000 series, released in 2026-05-31, while the Intel Core i3-14100T is a desktop processor from Core 14th Gen, released in 2024-01-07. The Intel part has a launch MSRP of $134; the AMD part has no recorded launch MSRP.

Clock speeds differ: AMD runs at 1.90 GHz base and 3.20 GHz boost, Intel at 2.70 GHz base and 4.40 GHz boost. TDP ratings also differ: AMD is rated at 15 W, Intel at 35 W. Sockets are incompatible: AMD uses Socket FP5, Intel uses Socket 1700.

The AMD part has 2 cores and 2 threads; the Intel part has 4 cores and 8 threads. Cache configurations differ as detailed above, with Intel holding the advantage in L2 and L3. Memory support: AMD is DDR4 only, Intel supports DDR4 and DDR5. ECC memory: AMD does not support it, Intel does. PCIe: AMD is Gen 3, Intel is Gen 5 with 16 lanes. Integrated graphics: Radeon Vega 8 versus UHD Graphics 730. The AMD part is built on 12 nm at GlobalFoundries with 4,940 million transistors and a 210 mm² die; the Intel part is 10 nm at Intel with no transistor count listed and a 163 mm² die.

Both processors have locked multipliers. The AMD part number is YM3100C4T2OFG, the Intel part number is SRMX0. Both are marked as Active in production status.

The Verdict

The data supports a clear verdict: the Intel Core i3-14100T is the substantially faster processor by every recorded benchmark metric. It wins all 11 head-to-head tests, with single-thread advantages of 54.5% and multithreaded advantages of 75.5% or more. The average benchmark score of 17,648 versus 6,247 places the Intel part in a different performance class, confirmed by the nearest rival clusters: Intel sits alongside Core i3-13100F and Ryzen 3 8300GE, while AMD sits alongside Ryzen Threadripper 1950X and EPYC 7272.

The Intel part also offers architectural advantages: 8 threads versus 2, 12 MB L3 versus 4 MB, DDR5 support, ECC memory, and Gen 5 PCIe. These are not marginal differences; they represent a generational leap in both core count and platform features.

The AMD Ryzen 3 3100U does have a lower TDP of 15 W versus 35 W, which could indicate lower power draw, but the database does not include any power consumption measurements to confirm efficiency under load. The AMD part also has a smaller L1 cache per core, but that does not translate into any benchmark win.

For users prioritizing raw compute performance, the Intel Core i3-14100T is the only choice based on recorded data. The AMD part's sole advantages are a lower TDP rating and a smaller physical footprint, but neither appears as a benchmark win.

Where Each One Wins

The Intel Core i3-14100T wins in every recorded workload category. The largest margins are in floating point math (-81.3%), extended instructions (-79.7%), and integer math (-78%). These are compute-heavy workloads that benefit from the Intel part's higher clocks, more threads, and larger cache. Data encryption (-75%), multithreaded performance (-75.5%), and physics (-76.2%) all show similar dominance.

Single-threaded workloads show the smallest relative gap at -54.5%, but even here Intel holds a decisive lead. Random string sorting at -70% and data compression at -74.8% round out the storage and memory-heavy tasks. Prime number finding at -67.9% is the second-smallest gap, still firmly in Intel's favor.

The AMD Ryzen 3 3100U does not win any head-to-head test. Its nearest rival comparisons show it performing within a narrow band of older high-end desktop parts like the Ryzen Threadripper 1950X and Core i9-7940X, but it never exceeds them. Its recorded strengths, if any, are not visible in the benchmark data. The 15 W TDP is the only specification where AMD holds a nominal advantage over Intel's 35 W, but the database provides no efficiency benchmark to quantify what that means in practice.

For use cases requiring maximum multi-threaded throughput, high single-core responsiveness, or support for modern platform features like DDR5 and ECC memory, the Intel Core i3-14100T is the only part backed by data. The AMD Ryzen 3 3100U remains a valid entry point for low-power mobile systems, but the recorded measurements show it at a consistent and substantial disadvantage across every tested metric.
