AMD Ryzen 5 7500F vs AMD Ryzen 5 7640U Comparison

The Verdict

The benchmark data presents a remarkably one-sided comparison. The AMD Ryzen 5 7500F wins all 19 recorded head-to-head tests against the AMD Ryzen 5 7640U, with no tests going the other way. The average benchmark score for the 7500F is 24,964, while the 7640U sits at 25,485, a difference of roughly 2% in the mobile chip’s favor when looking at the broader database average. However, the direct comparisons tell a different story: the desktop part leads by margins ranging from 8.3% to 62.8% depending on the workload.

For users building a desktop system, the 7500F is the clear choice based on raw performance. It delivers higher scores across every Cinebench iteration, Geekbench, and PassMark test in the database. The 7640U, being a mobile chip with a 15 TDP, is designed for a different purpose entirely. Its strength lies in efficiency and integration, not peak throughput. The data suggests that anyone needing sustained multi-threaded work should pick the 7500F, while the 7640U makes sense for portable systems where the Radeon 760M integrated graphics and lower power draw matter more than benchmark leadership.

The percentile rankings are nearly identical: the 7640U sits at the 78th percentile among all CPUs, and the 7500F at the 77th. This indicates that despite the head-to-head sweep, both chips occupy similar positions in the overall performance hierarchy. The 7640U’s nearest rivals include the AMD Ryzen 7 5700 with a delta of -0.1%, the AMD Ryzen 7 5825U at 0.2%, and the AMD Ryzen 7 7840U at 0.2%. The 7500F’s closest competitors are the Intel Core i7-11850H at 0.1%, the AMD Ryzen 5 8400F at -0.2%, and the Intel Core i7-13620H at 0.2%. These proximity scores show that both parts are competitive within their respective segments, even if their direct comparison is lopsided.

Architecture Differences

The two processors share the same Zen 4 architecture but diverge significantly in implementation. The 7640U uses the Phoenix codename and is built on a 4 nm process at TSMC, while the 7500F uses the Raphael codename on a 5 nm process. The transistor counts reflect this difference: the 7640U integrates 25,000 million transistors on a 178 mm² die, whereas the 7500F uses 6,570 million transistors on a 71 mm² die. This is a notable inversion, as the mobile chip packs far more transistors into a larger area, likely due to the integrated graphics and other SoC components.

The 7500F has no integrated graphics, with that field listed as null, while the 7640U includes the Radeon 760M. This is the most significant functional difference for users who do not plan to add a discrete GPU. The 7640U also uses the AMD Socket FP8, while the 7500F uses AMD Socket AM5. The 7500F has a higher base clock of 3.70 GHz and boost clock of 5.00 GHz, compared to the 7640U’s 3.50 GHz base and 4.90 GHz boost. Cache configurations also differ: both have 64 KB L1 and 1 MB L2 per core, but the 7500F has 32 MB shared L3, double the 7640U’s 16 MB shared L3.

PCIe support is another differentiator. The 7500F offers Gen 5 with 24 lanes (CPU only), while the 7640U provides Gen 4 with 20 lanes. Memory bandwidth also favors the desktop part at 83.2 GB/s versus 89.6 GB/s for the mobile chip, which is counterintuitive given the 7500F’s higher performance scores. Both support DDR5 and dual-channel memory, and both have ECC memory enabled. The 7500F has an unlocked multiplier, while the 7640U does not, which matters for overclocking enthusiasts.

Head-to-Head Benchmarks

The largest margin comes from PassMark’s find prime numbers test, where the 7500F scores 199 against the 7640U’s 74, a delta of -62.8%. This suggests a substantial advantage in integer-heavy, single-threaded workloads that depend on clock speed and cache. The 7500F’s higher boost clock of 5.00 GHz likely drives this outcome, combined with its larger 32 MB L3 cache.

Geekbench multicore shows the 7500F at 12,362 versus 8,595, a 30.5% lead. This is the second-largest delta and indicates strong scaling across all six cores. The Cinebench R23 multicore test reinforces this pattern: 22,799 for the 7500F against 17,936 for the 7640U, a 21.3% difference. The same delta of -21.3% appears across Cinebench R15 multicore, R20 multicore, and PassMark multithread, suggesting consistent multi-threaded performance scaling.

Single-threaded tests show smaller but still decisive gaps. Cinebench R23 single-core has the 7500F at 3,218 versus 2,532, a 21.3% lead. Geekbench single-core shows 2,374 versus 2,127, a 10.4% difference. PassMark single-thread scores are 3,841 versus 3,524, an 8.3% edge. These single-thread deltas are narrower than the multi-thread ones, which points to the clock speed advantage being the primary factor, while the cache and TDP differences amplify multi-threaded results.

PassMark physics has the 7500F at 1,788 against 1,169, a 34.6% lead. Data compression shows 305,925 versus 240,032, a 21.5% difference. Extended instructions favor the 7500F at 22,776 versus 17,019, a 25.3% gap. Floating-point math and integer math show smaller deltas of 12.9% and 10.9%, respectively, with the 7500F scoring 47,176 and 79,108 against the 7640U’s 41,093 and 70,483. Data encryption and random string sorting round out the list with 14.6% and 18.8% leads for the desktop chip.
