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

The AMD Ryzen 3 3100U and the Intel Core i7-14700T sit at opposite ends of the performance spectrum, and the benchmark data reflects this clearly. The Ryzen 3 3100U is a low-power mobile processor from AMD's 3000 series, while the Core i7-14700T is a high-core-count desktop chip from Intel's Core 14th Gen lineup. The recorded measurements show a decisive advantage for the Intel processor across every single test, with the Ryzen 3 3100U failing to secure a single win in the head-to-head comparison. The data indicates a fundamental gap in compute capability, driven by differences in core counts, architecture, and power targets, making these two processors suitable for entirely different workloads and system types.

Where Each One Wins

The head-to-head benchmark results are unambiguous: the Intel Core i7-14700T wins all 11 recorded tests, while the AMD Ryzen 3 3100U registers zero wins. This is not a close contest. The Intel processor dominates in both single-threaded and multi-threaded workloads, showing no weak points in the data. The Ryzen 3 3100U, by contrast, does not outperform its rival in any measured category, whether the task involves integer math, floating-point math, data compression, encryption, or prime number finding.

The use-case split therefore hinges on the magnitude of the Intel chip's advantage rather than a distribution of wins. For workloads that rely on raw multi-threaded throughput, such as rendering or heavy parallel computation, the Core i7-14700T is the clear choice based on its 30571 score in the Passmark multithread test versus 3348 for the Ryzen 3 3100U. For lightly threaded applications, the Intel processor still leads, as shown by its 3905 single-thread score compared to 1592 for the AMD chip. The Ryzen 3 3100U's only realistic position is in low-power mobile systems where its 15 TDP and integrated Radeon Vega 8 graphics align with a compact notebook design, but the data does not show any performance category where it wins outright.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 3 3100U uses the Picasso codename, built on the Zen+ architecture, and is manufactured on a 12 nm process at GlobalFoundries. It is a 2-core, 2-thread part with a base clock of 1.90 GHz and a boost clock of 3.20 GHz, housed in a 15 TDP package that fits the AMD Socket FP5 mobile platform. The Intel Core i7-14700T, in contrast, uses the Raptor Lake-R codename with a Raptor Lake architecture, manufactured on a 10 nm process at Intel. It offers 20 cores and 28 threads, a base clock of 1.30 GHz, and a boost clock of 5.20 GHz, with a 35 TDP and an Intel Socket 1700 desktop form factor.

Cache configurations also differ sharply. The Ryzen 3 3100U provides 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Core i7-14700T offers 80 KB of L1 per core, 2 MB of L2 per core, and a much larger 33 MB of shared L3 cache. The die size tells part of the story: the AMD chip measures 210 mm² with 4,940 million transistors, while the Intel chip is larger at 257 mm², though its transistor count is not recorded in the database. Memory support also differs, with the Ryzen 3 3100U limited to DDR4 and the Core i7-14700T supporting both DDR4 and DDR5. The Intel processor also enables ECC memory, while the AMD chip does not. PCIe capabilities diverge as well, with the Ryzen 3 3100U using Gen 3 and the Core i7-14700T using Gen 5 with 16 lanes on the CPU. The integrated graphics differ, with Radeon Vega 8 on the AMD side and UHD Graphics 770 on the Intel side.

Head-to-Head Benchmarks

The largest margins in the data appear in the math-heavy tests. In Passmark floating-point math, the Intel Core i7-14700T scores 79042 against 5854 for the Ryzen 3 3100U, a delta of -92.6 percent. Integer math shows a similar pattern: 113854 for the Intel chip versus 8873 for the AMD chip, a -92.2 percent difference. These are the two biggest percentage gaps in the entire comparison, indicating that the Intel processor's compute throughput is roughly an order of magnitude higher in these workloads.

Data compression and encryption also show massive gaps. The Intel chip scores 354216 in data compression against 38455 for the AMD chip, a -89.1 percent difference. In data encryption, the Intel processor scores 21277 versus 1972, a -90.7 percent gap. Extended instructions follow the same trend, with 20052 for Intel and 2116 for AMD, a -89.4 percent difference. Prime number finding shows 145 for Intel versus 18 for AMD, a -87.6 percent gap, and random string sorting shows 38546 for Intel versus 4666 for AMD, a -87.9 percent difference.

The multithreaded and physics tests reinforce the overall picture. Passmark multithread scores are 30571 for the Intel chip and 3348 for the AMD chip, a -89 percent delta. The physics test shows 1946 for Intel versus 232 for AMD, a -88.1 percent difference. Even the single-thread test, where the gap might be expected to narrow, shows a substantial lead: 3905 for the Intel chip versus 1592 for the AMD chip, a -59.2 percent delta. The smallest percentage gap in the entire dataset is still a 59.2 percent deficit for the AMD processor, which underscores how consistently the Intel chip outperforms it.

The Verdict

The data points to a simple conclusion: the Intel Core i7-14700T is the superior processor in every recorded benchmark. Its average benchmark score of 41914 places it in the 88th percentile of all CPUs, while the AMD Ryzen 3 3100U has an average score of 6247 and sits in the 62nd percentile. The Intel chip's nearest rivals in the database, such as the AMD Ryzen 9 PRO 8945HS with a -0.1 percent delta and the Intel Core i7-12850HX with a 0.3 percent delta, show that it competes with far more powerful processors than the Ryzen 3 3100U. The AMD chip's nearest rivals, including the AMD Ryzen Threadripper 1950X and the Intel Core i9-10920X, are in a completely different performance class, and even those comparisons show only a 1.6 percent delta at most.

For a system builder, the choice depends entirely on the platform and workload. The Core i7-14700T is a desktop processor with a 35 TDP, 20 cores, and 28 threads, designed for heavy multi-threaded tasks and high single-thread responsiveness. The Ryzen 3 3100U is a mobile processor with a 15 TDP, 2 cores, and 2 threads, suited to low-power notebooks where battery life and heat matter more than raw performance. The Intel chip also supports both DDR4 and DDR5 memory, ECC memory, and PCIe Gen 5, making it a more flexible and future-ready option. The Ryzen 3 3100U is limited to DDR4 and PCIe Gen 3, which constrains its expansion and memory bandwidth capabilities. The 38.4 GB/s memory bandwidth recorded for the AMD chip is a figure the Intel chip does not list, but the Intel processor's larger cache and higher core count more than compensate in the measured tests.

Neither processor is a wrong choice when matched to its intended use case, but the data does not support any scenario where the Ryzen 3 3100U outpaces the Core i7-14700T. The Intel chip delivers roughly nine times the multithreaded performance in several tests and more than double the single-thread performance, making it the only reasonable pick for demanding workloads.
