AMD Ryzen 5 7400 vs Intel Core i7-14650HX Comparison

The AMD Ryzen 5 7400 and the Intel Core i7-14650HX are two very different processors aimed at different segments, yet they land in a similar performance bracket. The data shows the Intel part wins every single head-to-head benchmark, but the margin of victory varies wildly depending on the workload. This analysis breaks down exactly where the 14650HX dominates, where the gap is narrow, and what that means for a builder choosing between a desktop AM5 chip and a mobile BGA part.

Head-to-Head Benchmarks

The Intel Core i7-14650HX is the outright winner in all 11 shared PassMark tests. The most lopsided result is in floating-point math, where Intel scores 84,999 against AMD's 40,784 — a 52% advantage. This is a massive gap, nearly double the throughput, indicating a clear edge in scientific and engineering workloads that rely heavily on FPU performance. Similarly, find prime numbers shows a 48% delta (152 vs 79), which is a strong proxy for pure integer arithmetic speed.

The multi-core tests tell a similar story, though with slightly smaller margins. In PassMark multithread, the Intel chip scores 33,495 versus the AMD's 21,712, a 35.2% lead. The integer math test shows a 44.5% gap (116,661 vs 64,733), and physics scoring is 47.8% in favor of Intel (2,202 vs 1,150). These are not narrow victories; they are category-level wins that suggest the 14650HX is in a different performance class for heavily threaded workloads.

The 14650HX also wins the data compression test, scoring 398,418 against 261,749 (34.3% ahead), and data encryption with 22,917 vs 14,865 (35.1% ahead). Random string sorting is closer but still Intel-favored at 43,035 vs 31,110, a 27.7% delta. Extended instructions see a smaller but meaningful 17.5% gap (24,150 vs 19,924). The narrowest margin is in single-thread performance, where the Intel chip scores 3,841 versus AMD's 3,248 — a 15.4% lead. While still a clear win for Intel, this is the area where the two are most comparable, suggesting the Zen 4 architecture's per-core efficiency helps close the gap against a chip with a higher boost clock.

Architecture Differences

The fundamental divide is between a 6-core desktop chip and a 16-core mobile chip. The AMD Ryzen 5 7400 uses Zen 4 architecture on a 5 nm TSMC process, while the Intel Core i7-14650HX uses Raptor Lake on Intel's 10 nm process. The die sizes reflect this: AMD's Raphael chip is 71 mm², while Intel's Raptor Lake-HX is 257 mm². The transistor count is only listed for the AMD part at 6,570 million, but the physical size difference hints at the Intel's larger, more complex layout.

Core counts are the biggest differentiator. The 7400 has 6 cores and 12 threads, while the 14650HX has 16 cores and 24 threads. This explains the massive multi-threaded advantage. Cache hierarchies also differ: the AMD chip has 64 KB of L1 and 1 MB of L2 per core, with 16 MB of shared L3. The Intel part has 80 KB L1 and 2 MB L2 per core, plus 30 MB of shared L3. That larger L3 pool is a major factor in the compression and encryption wins.

Clock speeds tell a different story. The AMD has a base of 3.30 GHz and boosts to 4.30 GHz, while the Intel has a lower 2.20 GHz base but a much higher 5.20 GHz boost. The lower base is typical of a mobile part designed for thermal constraints, but the high boost is what drives its single-thread wins. Memory support also diverges: the AMD is DDR5-only with a dual-channel bus and 83.2 GB/s bandwidth, while the Intel supports both DDR4 and DDR5. The Intel's integrated graphics is UHD Graphics 710, whereas the AMD has Radeon Graphics. Both support ECC memory and have unlocked multipliers.

The platform differences are stark. The AMD uses Socket AM5 and is a desktop part, while the Intel uses BGA 1964 and is a mobile part. PCIe lanes also differ: the AMD offers Gen 5 with 24 CPU lanes, while the Intel offers Gen 5 with 16 CPU lanes. The release dates are separated by roughly a year and a half, with the Intel launching in January 2024 and the AMD in September 2025.

Where Each One Wins

Given that the Intel wins every benchmark, it is tempting to declare it the superior processor outright. However, the context matters. The 14650HX is a 16-core mobile monster designed for high-end laptops. Its wins are most pronounced in multi-threaded tasks: rendering, video encoding, data compression, and physics simulations. The 52% lead in floating-point math makes it a strong choice for number-crunching applications like scientific computing or financial modeling. The 44.5% lead in integer math similarly favors software compilation and data processing.

The AMD Ryzen 5 7400's only "wins" are qualitative. It is a desktop chip with a much lower TDP of 65 watts versus Intel's 55 watts (though that mobile figure is likely a base rating). Its 5nm process node is more advanced than Intel's 10nm, which typically translates to better power efficiency per core. The 7400 also has a smaller die and supports more PCIe lanes (24 vs 16), which is relevant for builders planning to run multiple GPUs or NVMe drives. In single-thread performance, the gap narrows to 15.4%, meaning for everyday tasks like web browsing or office work, the difference would be less noticeable.

The data shows the AMD chip's closest rivals are the Intel Core i7-14700T (0.3% behind) and the Intel Core i7-12850HX (0.7% behind), while the Intel 14650HX's rivals include the AMD Ryzen 9 5900X (0.5% ahead) and the Intel Core Ultra 7 265H (-0.1% behind). This places both CPUs in the same overall percentile (88th), but the benchmark distribution is clearly different.

The Verdict

From the data alone, the Intel Core i7-14650HX is the faster processor in every measured category. If you are choosing strictly on benchmark scores, the Intel wins, and often by a wide margin. It is especially dominant in multi-threaded and floating-point workloads, where its 16 cores and 30 MB of L3 cache deliver massive advantages. For a user who prioritizes raw throughput in rendering, data analysis, or heavy multitasking, the 14650HX is the clear choice from a performance standpoint.

However, the AMD Ryzen 5 7400 is not without merit. It is a modern desktop part on a more advanced process node, with a smaller footprint and more PCIe lanes. Its single-thread deficit is the smallest gap of any test, and for a desktop user who values upgradability (Socket AM5) and a simpler cooling solution, the 7400 could be a reasonable pick — but only if the workload is light and the 15-35% performance gaps in other areas are acceptable. The benchmarks do not show any task where the AMD wins, so the verdict is straightforward: pick the Intel if you want the best scores, and pick the AMD only if the platform features (AM5, more PCIe lanes, advanced node) matter more to you than the measured performance deltas.
