AMD Ryzen 5 PRO 8540U vs Intel Core i5-14490F Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core i5-14490F across all 17 benchmark comparisons. The AMD Ryzen 5 PRO 8540U does not register a single win in any of the head-to-head tests, with the Intel part taking every multi-core and single-core discipline. The margins vary substantially, ranging from a modest 8% gap in single-threaded PassMark tests to a 53% deficit in the PassMark physics workload.

Starting with the Cinebench series, the Intel Core i5-14490F posts consistently large advantages. In Cinebench R23 multi-core, the Intel chip scores 23000 against the AMD part's 15456, a 32.8% delta. The same 32.8% gap appears in Cinebench R20 multi-core (9660 versus 6491) and Cinebench R15 multi-core (2318 versus 1557). The single-core Cinebench results follow the same pattern: R23 shows 3247 versus 2182, R20 shows 1363 versus 916, and R15 shows 327 versus 219, all with deltas between 32.8% and 33%.

The PassMark suite reveals where the Intel architecture pulls further ahead. The largest single delta is in floating-point math, where the Intel chip scores 66558 against 34865, a 47.6% advantage. Physics testing shows the widest gap of all: 2093 versus 983, meaning the Intel part is 53% ahead. Prime number finding also shows a steep difference at 45.9%, with scores of 122 versus 66. Data compression favors Intel by 39.5% (340026 versus 205703), while integer math shows a 35.4% delta (87844 versus 56738). Multithreaded PassMark performance lands at 28662 versus 18218, a 36.4% gap.

The narrowest margins appear in single-threaded workloads. PassMark single-thread scores show 3873 versus 3563, an 8% delta, the closest result in the entire comparison. Data encryption sits at 32.4% (18225 versus 12319), extended instructions at 29.1% (21731 versus 15410), and random string sorting at 30.4% (35608 versus 24797). Across every metric, the Intel Core i5-14490F wins, and the average benchmark score difference is substantial: 38149 versus 23709, a 61% higher average for the Intel part. The percentile rankings confirm this: Intel sits at the 86th percentile among all CPUs, while AMD sits at the 76th.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 PRO 8540U uses the Zen 4 architecture on a 4 nm TSMC process, codenamed Hawk Point, and belongs to the 8000 series. The Intel Core i5-14490F uses the Raptor Lake architecture on a 10 nm Intel process, part of the Core 14th Gen family with the Raptor Lake-R codename. The process node gap alone explains part of the efficiency difference: the AMD die measures 137 mm² with 20,900 million transistors, while the Intel die is larger at 215 mm² with no transistor count recorded.

Core configurations differ sharply. The AMD part has 6 cores and 12 threads, while the Intel part has 10 cores and 16 threads. Both use a dual-channel memory bus, but the AMD chip supports only DDR5 with a recorded memory bandwidth of 89.6 GB/s, whereas the Intel chip supports both DDR4 and DDR5 with no bandwidth figure recorded. The AMD chip includes ECC memory support; the Intel chip does not. Cache layouts also diverge: AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3.

The platform targets are clearly different. The AMD Ryzen 5 PRO 8540U uses AMD Socket FP7, is classified as a mobile processor, and includes integrated Radeon 740M graphics. The Intel Core i5-14490F uses Intel Socket 1700, is a desktop part, and has no integrated graphics (listed as N/A). The PCIe support also differs: AMD provides Gen 4 with 14 lanes, while Intel provides Gen 5 with 16 lanes. The Intel chip boosts to 5.00 GHz against the AMD's 4.90 GHz, though the AMD base clock of 3.20 GHz is higher than Intel's 2.50 GHz. The TDP rating shows a major split: 28 watts for the AMD mobile part versus 65 watts for the Intel desktop part. Neither chip has an unlocked multiplier, and both are listed as active production parts.

Where Each One Wins

Given the benchmark sweep, the Intel Core i5-14490F wins in every measured category. The data shows no workload where the AMD Ryzen 5 PRO 8540U takes the lead. However, the magnitude of the Intel advantage varies by workload type, which points to different relative strengths.

For heavily parallel workloads, the Intel part is dominant. The physics test shows the largest gap at 53%, and floating-point math follows at 47.6%. Prime number finding also favors Intel heavily at 45.9%. These results align with the Intel chip's higher core count and thread count: 10 cores and 16 threads against 6 cores and 12 threads. Multi-core Cinebench scores all show the same 32.8% gap, indicating a consistent scaling advantage in rendering tasks.

For memory-sensitive workloads, the Intel advantage narrows somewhat. Data compression shows a 39.5% gap, random string sorting shows 30.4%, and integer math shows 35.4%. These still favor Intel but less dramatically than the compute-heavy physics or floating-point tests. The single-threaded PassMark test shows the smallest gap at 8%, suggesting that the per-core performance difference is much smaller than the core-count difference. The Intel single-core Cinebench deltas hover around 33%, though, which complicates that picture.

The AMD part's lower TDP and mobile classification suggest its intended role is power-constrained environments. The data does not show any benchmark where that translates into a performance win, but the 28-watt rating versus 65 watts implies a very different thermal envelope. The AMD chip includes integrated graphics and ECC support, features absent from the Intel part, which may matter for specific system designs even though they do not appear in the benchmark scores.

The Verdict

The benchmark data delivers a clear answer: the Intel Core i5-14490F outperforms the AMD Ryzen 5 PRO 8540U in every recorded test. The average benchmark score of 38149 for Intel against 23709 for AMD represents a 61% advantage, and the Intel part sits at the 86th percentile versus the AMD's 76th. For any workload measured in this database, the Intel chip is the stronger performer.

The closest contest appears in single-threaded PassMark tests, where the Intel lead shrinks to 8%. That suggests that for lightly threaded tasks, the two chips are relatively comparable in per-core capability. But even there, Intel wins, and the gap widens dramatically as thread counts rise. The physics workload, which often responds to both core count and memory bandwidth, shows the largest deficit for AMD at 53%.

The rationale for choosing the AMD part would come from factors outside raw benchmark scores. The 28-watt TDP, the integrated Radeon 740M graphics, the ECC memory support, and the mobile socket classification all point to a design intended for compact or power-sensitive systems. The Intel part requires a discrete graphics solution, draws 65 watts, and targets desktop sockets. The data does not show any performance scenario where the AMD chip wins, so the decision rests on platform requirements rather than measured speed.

The Intel Core i5-14490F also holds a release date advantage, appearing on 2023-12-31 compared to the AMD's 2024-04-15. Both parts remain in active production. The nearest rivals for each chip reinforce their positioning: the AMD sits near the Intel Core i5-11500 and AMD Ryzen 7 8840U, while the Intel sits near the Intel Core i5-13600KF and Core Ultra 5 245T. The Intel part competes in a higher performance bracket.
