AMD Ryzen 3 3100U vs Intel Core i7-14700 Comparison

Head-to-Head Benchmarks

The benchmark data presents an unambiguous picture: the Intel Core i7-14700 wins every recorded head-to-head test against the AMD Ryzen 3 3100U. The database records 11 shared benchmark comparisons, and the Intel part claims victory in all 11. The margins are consistently large, though they vary by workload type.

The smallest gap appears in single-thread performance. The Intel Core i7-14700 scores 4236 in the PassMark single-thread test, while the AMD Ryzen 3 3100U manages 1592. That places the Intel part 62.4% ahead, a substantial advantage for lightly threaded tasks. The same delta appears in the duplicate singlethread entry, confirming the result.

Multi-threaded workloads widen the divide considerably. In the PassMark multithread test, the Intel Core i7-14700 scores 40318 against 3348 for the AMD part, a 91.7% lead. Integer math shows an even larger gap: 154535 versus 8873, putting the Intel chip 94.3% ahead. Floating-point math follows a similar pattern, with the Intel part scoring 106716 against 5854, a 94.5% margin.

Data compression results reinforce the trend. The Intel Core i7-14700 records 498198 in the PassMark data compression test, while the AMD Ryzen 3 3100U scores 38455. That is a 92.3% deficit for the AMD chip. Data encryption shows a 93.3% gap, with scores of 29601 and 1972 respectively.

Extended instruction workloads behave the same way. The Intel part scores 28388 in PassMark extended instructions, versus 2116 for the AMD chip, a 92.5% difference. Prime number finding shows a 89% gap (164 versus 18). Random string sorting delivers a 91.4% gap (54340 versus 4666). Physics simulation rounds out the set with a 89.6% gap (2226 versus 232).

The average benchmark scores place these processors in completely different tiers. The Intel Core i7-14700 holds an average score of 52301, ranking in the 91st percentile of all CPUs in the database. The AMD Ryzen 3 3100U averages 6247, sitting in the 62nd percentile. The nearest rivals confirm the separation: the Intel part trades positions with the Intel Xeon Gold 5320H (52431, 0.2% behind), the AMD EPYC 8124P (52121, 0.3% ahead), the Intel Core Ultra 5 235HX (52073, 0.4% ahead), and the AMD Ryzen 9 5950X (51947, 0.7% ahead). The AMD Ryzen 3 3100U sits alongside the AMD Ryzen Threadripper 1950X (6231, 0.3% ahead) and the Intel Core i9-10920X (6347, 1.6% behind).

Architecture Differences

The two processors come from different design philosophies and different market segments. The AMD Ryzen 3 3100U uses the Picasso architecture, built on a 12 nm process at GlobalFoundries. It is a mobile part with 2 cores and 2 threads, meaning it lacks simultaneous multithreading. The Intel Core i7-14700 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 20 cores and 28 threads, a hybrid configuration that the AMD chip does not attempt.

The transistor counts reflect the scale difference. The AMD part integrates 4,940 million transistors on a 210 mm² die. The Intel part does not have a recorded transistor count in the database, but its die size is 257 mm². The cache hierarchies diverge sharply. The AMD Ryzen 3 3100U provides 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel Core i7-14700 provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The L3 difference alone is substantial: 33 MB versus 4 MB.

Memory support also differs. The AMD chip supports DDR4 only, running on a dual-channel bus with 38.4 GB/s of bandwidth. The Intel chip supports both DDR4 and DDR5, also on a dual-channel bus, but the database does not record a bandwidth figure for it. ECC memory is supported on the Intel part but not on the AMD part. PCIe connectivity differs as well: the AMD chip runs Gen 3, while the Intel part runs Gen 5 with 16 CPU lanes.

Integrated graphics present another divergence. The AMD Ryzen 3 3100U carries Radeon Vega 8, while the Intel Core i7-14700 carries UHD Graphics 770. The database records no benchmark scores for either integrated GPU, so a direct comparison is not possible from the recorded data.

Where Each One Wins

Based strictly on the recorded benchmarks, the Intel Core i7-14700 wins in every measurable category. No workload in the database favors the AMD Ryzen 3 3100U. The closest contest is single-thread performance, where the Intel part leads by 62.4%. That remains a decisive margin, but it is the smallest gap recorded.

The Intel part shows its largest advantages in floating-point math (94.5% ahead) and integer math (94.3% ahead). These are heavily parallel workloads, and the 20-core, 28-thread configuration of the Intel chip explains the result. The AMD part, with 2 cores and 2 threads, simply cannot scale to the same level.

For workloads that depend on single-core speed, such as lightly threaded applications, the Intel part still holds a clear edge, but the gap narrows. The 62.4% lead in single-thread tests indicates that the Intel architecture delivers meaningfully higher per-core performance, not just more cores.

The AMD Ryzen 3 3100U does not win any recorded benchmark. Its position in the 62nd percentile of all CPUs, with an average score of 6247, places it in the lower-middle range of the database. The Intel Core i7-14700, at the 91st percentile with an average score of 52301, sits comfortably in the upper tier.

The Verdict

The recorded data leaves no ambiguity. The Intel Core i7-14700 outperforms the AMD Ryzen 3 3100U in every benchmark shared between the two. The smallest margin is 62.4% in single-thread performance; the largest is 94.5% in floating-point math. The Intel part's 20 cores, 28 threads, 33 MB of L3 cache, and higher boost clock of 5.40 GHz combine to produce an average score of 52301, which places it at the 91st percentile. The AMD part, with 2 cores, 2 threads, 4 MB of L3 cache, and a 3.20 GHz boost clock, averages 6247 and sits at the 62nd percentile.

The AMD Ryzen 3 3100U is a mobile processor with a 15 W TDP, designed for low-power systems. The Intel Core i7-14700 is a desktop processor with a 65 W TDP, designed for high-performance builds. The specification differences align with these market positions. The Intel part uses a larger die (257 mm² versus 210 mm²), supports newer memory (DDR5 in addition to DDR4), and offers ECC support. The AMD part uses a smaller process node (12 nm versus 10 nm), but that does not translate into a performance advantage in the recorded benchmarks.

For users selecting between these two processors, the data supports a straightforward choice. The Intel Core i7-14700 delivers superior performance across every measured workload, from single-threaded tasks to heavily parallel computations. The AMD Ryzen 3 3100U does not win a single recorded benchmark. The database shows no scenario where the AMD part is the better performer. The decision rests on the intended use case: the AMD chip fits low-power mobile systems, while the Intel chip serves desktop workloads that demand high multi-threaded throughput.
