Architecture Differences

The two processors diverge significantly in their underlying architecture. The AMD Ryzen 5 7500X3D is built on the Zen 4 architecture, codenamed Raphael, and is part of the 7000 series. It is a desktop processor designed for AMD Socket AM5. In contrast, the Intel Core 3 100U uses the Raptor Lake architecture, specifically Raptor Lake-U, and is a mobile processor on Intel BGA 1744.

Core and thread configurations are a primary distinction. Both chips have 6 physical cores, but the AMD processor supports 12 threads through simultaneous multithreading, while the Intel part supports 8 threads. This thread advantage contributes to the AMD chip's substantial lead in multi-threaded benchmarks. Clock speeds also differ: the AMD chip has a base clock of 4.00 GHz and a boost clock of 4.50 GHz, whereas the Intel chip has a much lower base clock of 1.20 GHz but a higher boost clock of 4.70 GHz.

Cache hierarchies are vastly different. The AMD Ryzen 5 7500X3D uses 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a large 96 MB shared L3 cache. The Intel Core 3 100U has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and only 10 MB of shared L3 cache. The AMD chip's larger L3 cache is a defining feature, likely contributing to its strong performance in data-intensive workloads.

Memory support and I/O also separate the two. The AMD processor supports DDR5 memory with a dual-channel bus and a recorded memory bandwidth of 83.2 GB/s. It also offers PCIe Gen 5 with 24 lanes from the CPU. The Intel chip supports both DDR4 and DDR5 in a dual-channel configuration, but its memory bandwidth is not listed in the database. It provides PCIe Gen 4 with 8 lanes from the CPU. The AMD chip includes integrated Radeon Graphics, while the Intel chip features UHD Graphics 64EU. Power targets differ sharply: the AMD part has a TDP of 65 watts, while the Intel part has a TDP of 15 watts, reflecting their desktop versus mobile design goals.

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the AMD Ryzen 5 7500X3D, winning 9 of the 11 recorded head-to-head tests. The magnitude of these wins is often large. In the PassMark data compression test, the AMD chip scores 271649 against 136497 for the Intel chip, a 99% delta. Data encryption shows a similar pattern: 15797 versus 8128, a 94.4% delta. The extended instructions test reveals a 159.1% delta (20455 vs 7894). Prime number finding shows the largest relative gap at 325% (221 vs 52). Floating point math is 53.9% ahead (43594 vs 28322), and integer math is 78.8% ahead (70774 vs 39580). The multi-thread test is exactly 100% ahead (25047 vs 12522). Physics scores favor the AMD chip heavily with a 217.2% delta (2779 vs 876). Random string sorting sees a 117.2% delta (32999 vs 15191).

The Intel Core 3 100U wins only the PassMark single-thread and single-thread duplicate tests, with a score of 3506 versus 3494, a delta of -0.3% from the AMD chip's perspective. This is an extremely narrow margin, indicating that the two processors are essentially tied in single-threaded performance as measured by this specific test.

The Verdict

The data presents a clear performance hierarchy. The AMD Ryzen 5 7500X3D is the substantially faster processor in almost every measured category. Its average benchmark score of 44573 is over 2.7 times the Intel Core 3 100U's score of 16148. The AMD chip also ranks in the 89th percentile of all CPUs, compared to the Intel chip's 70th percentile. For users requiring maximum processing throughput, the AMD part is the clear choice based on these results.

The Intel Core 3 100U's only recorded victory is a marginal 0.3% lead in single-threaded performance. Its 15-watt TDP, however, positions it as a low-power mobile part, which is a significant attribute for portable devices. The database does not measure power efficiency directly, but the TDP difference is substantial. For users prioritizing raw compute performance, the AMD Ryzen 5 7500X3D is the superior option. For scenarios where the 15-watt power envelope of the Intel chip is a critical requirement, it serves that specific need.

Where Each One Wins

The AMD Ryzen 5 7500X3D wins in all multi-threaded and compute-heavy workloads recorded in the database. This includes data compression, data encryption, extended instruction sets, prime number finding, floating point math, integer math, multi-thread tests, physics calculations, and random string sorting. The deltas range from 53.9% to 325%, indicating a massive advantage across these categories. This processor is suited for tasks that rely on parallel processing and large cache access.

The Intel Core 3 100U wins solely in the single-thread and single-thread duplicate tests, with a 0.3% margin. This is a narrow victory. The Intel chip's 15-watt TDP and mobile market segment suggest it is designed for power-constrained environments, but the benchmark data does not provide a direct performance-per-watt metric. Its lower thread count and smaller cache also place it at a disadvantage in the multi-threaded tests recorded. The database shows that for any workload beyond a specific single-threaded operation, the AMD Ryzen 5 7500X3D delivers significantly higher performance.
