Architecture Differences

The AMD Ryzen 5 PRO 8640U belongs to the 8000 series and uses the Zen 4 architecture under the Hawk Point codename. It is fabricated on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die. The Intel Core 3 304 uses the Wildcat Lake codename, built on Intel's 3 nm process, with transistor count and die size not recorded in the database.

Cache configurations diverge sharply. The AMD chip allocates 64 KB of L1 cache per core and 1 MB of L2 cache per core, plus 16 MB of shared L3 cache. The Intel chip lists 192 KB of total L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The per-core L2 allocation on the Intel part is 0.5 MB per core, whereas the AMD part provides 1 MB per core.

Memory architecture also separates the two. The AMD Ryzen 5 PRO 8640U runs dual-channel DDR5 with 89.6 GB/s peak bandwidth. The Intel Core 3 304 runs single-channel memory with 59.7 GB/s peak bandwidth, though it adds LPDDR5X support to its compatibility list. ECC memory is available on the AMD part but absent on the Intel part.

PCIe connectivity differs as well. The AMD processor provides Gen 4 with 20 lanes from the CPU. The Intel processor provides Gen 4 with 6 lanes from the CPU. Integrated graphics also differ: the AMD part uses Radeon 760M, while the Intel part uses Intel Xe3 Graphics with 1 Xe core.

The AMD chip operates at a base clock of 3.50 GHz and a boost clock of 4.90 GHz, with a 28 W TDP. The Intel chip runs at a base clock of 1.50 GHz and a boost clock of 4.30 GHz, with a 15 W TDP. The Intel part has a launch MSRP of $309, while no launch MSRP is recorded for the AMD part. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The benchmark database records 17 head-to-head comparisons between these two mobile processors, and the AMD Ryzen 5 PRO 8640U wins all 17. No test favors the Intel Core 3 304.

The largest gap appears in Cinebench R23 multi-core, where the AMD part scores 19,982 versus 5,263 for the Intel part, a 279.7% delta. This result reflects the combination of more cores, more threads, and higher clocks on the AMD side. Cinebench R20 multi-core shows a 101.7% advantage (8,392 versus 4,160), while Cinebench R15 multi-core shows a 137.2% advantage (2,014 versus 849).

Integer math in PassMark produces the second-largest margin. The AMD chip scores 74,875 versus 24,640 for the Intel chip, a 203.9% delta. Random string sorting follows with a 135.1% gap (32,114 versus 13,659), and data compression shows a 127.3% delta (260,925 versus 114,775).

The AMD lead narrows in several workloads but remains decisive. PassMark extended instructions shows a 97.5% advantage (19,130 versus 9,686). PassMark multithread delivers a 96.1% delta (22,795 versus 11,625). Data encryption shows 86.4% (15,843 versus 8,501). Floating point math shows 52.3% (45,265 versus 29,722). Physics shows 32.9% (1,154 versus 868).

Find prime numbers presents one of the closest results, with the AMD part scoring 78 versus 68 for the Intel part, a 14.7% margin. Single-core tests are also relatively tight. Cinebench R15 single-core shows a 7.6% delta (284 versus 264), and PassMark single-thread shows a 3.3% delta (3,732 versus 3,614). Cinebench R20 single-core shows a 101.7% delta (1,184 versus 587), which is an outlier compared to the other single-thread results, likely due to workload characteristics.

The AMD part's average benchmark score across the database is 30,254, placing it in the 81st percentile of all CPUs. The Intel part averages 13,745, placing it in the 68th percentile. The AMD chip's nearest rivals include the AMD Ryzen 7 2700X (0.1% ahead), the AMD Ryzen 7 7736U (0.4% behind), and the AMD Ryzen 5 7640HS (0.4% behind).

The Verdict

The recorded data provides a clear answer for multi-threaded workloads. The AMD Ryzen 5 PRO 8640U dominates the Intel Core 3 304 across every recorded benchmark, with margins ranging from 3.3% in PassMark single-thread to 279.7% in Cinebench R23 multi-core. The AMD part's 12 threads versus 5 threads, its dual-channel memory bus, and its higher base and boost clocks all contribute to this outcome.

The AMD chip sits in the 81st percentile of all CPUs with an average score of 30,254, while the Intel chip sits in the 68th percentile with an average score of 13,745. The nearest rivals for the AMD part, such as the Ryzen 7 2700X and the Ryzen 7 7736U, are within 0.4% of its average score, indicating it performs at a level comparable to those established desktop and mobile chips. The Intel part's nearest rivals, including the Core i7-8750H and the Core 5 120UL, cluster within 1.4% of its average score.

For users selecting a processor based on the database measurements, the AMD Ryzen 5 PRO 8640U is the stronger option in every recorded workload. The Intel Core 3 304 offers a lower TDP of 15 W versus 28 W, which may matter for power-constrained designs, and it uses a newer 3 nm process node. It also includes LPDDR5X memory support. However, the benchmark results show no workload where the Intel part gains an advantage.

The Intel part's single-thread scores are comparatively close to the AMD part in PassMark (3,614 versus 3,732), but the Cinebench R23 single-core result shows a 59.8% gap in favor of AMD. The Intel part's multi-core scores are consistently less than half of the AMD part's scores, and in Cinebench R23 the AMD part is nearly four times faster.

The data indicates that the AMD Ryzen 5 PRO 8640U is the appropriate choice for compute-heavy mobile workloads, including rendering, encryption, and data compression. The Intel Core 3 304, with its lower TDP and 3 nm process, may suit designs where power efficiency takes priority over raw performance, but its single-channel memory and lack of SMT limit its throughput in parallel tasks. The AMD part wins all 17 head-to-head comparisons, and no recorded metric favors the Intel part.
