Where Each One Wins

The benchmark data shows a complete sweep: the AMD Ryzen 5 PRO 8645HS wins all 17 head-to-head comparisons against the Intel Core 3 304. The margin structure, however, reveals where each processor is relatively stronger. The AMD chip's multi-threaded and compute-heavy workloads show the largest gaps, while single-threaded tests show the narrowest margins.

In multi-core rendering, the AMD part dominates. Cinebench R23 multi-core shows a 275.1% delta, Cinebench R15 multi-core shows 134.3%, and Cinebench R20 multi-core shows 99.3%. These are the kinds of workloads that scale with core count, thread count, and sustained power delivery. The AMD part's 6 cores with 12 threads, combined with a 45 W TDP, clearly outperforms the Intel part's 5 cores with 5 threads at 15 W.

Integer-heavy and data-processing workloads also show massive AMD advantages. PassMark integer math shows a 195.2% delta, random string sorting shows 159.7%, and data compression shows 131.6%. These results point to the AMD processor being the stronger choice for general productivity, compilation, and data manipulation tasks that rely on parallel integer execution.

The Intel Core 3 304 is not without relative strengths, even if it loses every test. Its closest margins are in single-threaded performance: PassMark single thread shows a 6.8% delta, Cinebench R15 single-core shows 6.1%, and PassMark find prime numbers shows 7.4%. These are the areas where the Intel chip, despite its lower TDP and fewer threads, comes closest to matching the AMD part. For lightly threaded workloads that do not stress the whole package, the Intel processor is comparatively less disadvantaged.

The Intel part also keeps the gap relatively smaller in floating-point math (53% delta) and physics (39.2% delta), suggesting that its efficiency-oriented design can still handle some compute tasks without falling as far behind as it does in multi-core rendering or integer throughput.

Architecture Differences

The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture under the Hawk Point codename, part of the 8000 series. It is built 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 under the Core 3 generation, fabricated on a 3 nm process at Intel. The database does not list transistor count or die size for the Intel part.

Cache hierarchies differ substantially. The AMD chip allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip lists 192 KB of L1 total, 2.5 MB of L2 total, and 6 MB of shared L3. The AMD part's per-core L2 allocation and larger L3 pool benefit workloads that repeatedly access working sets.

Memory architecture also separates the two. AMD supports dual-channel DDR5 with 89.6 GB/s bandwidth and ECC memory. Intel supports DDR5 and LPDDR5X but only in single-channel mode at 59.7 GB/s, with no ECC support. The bandwidth difference of roughly 30 GB/s affects memory-sensitive applications.

PCIe lanes differ: AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 4 with 6 lanes (CPU only). This gives the AMD platform more headroom for additional devices or expansion.

Integrated graphics differ as well. AMD uses the Radeon 760M, while Intel uses Xe3 Graphics with 1 Xe core. The database does not provide graphics benchmark scores, so only the configuration difference can be noted.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 5 PRO 8645HS has 6 cores and 12 threads, while the Intel Core 3 304 has 5 cores and 5 threads. Base clocks are 4.30 GHz for AMD versus 1.50 GHz for Intel, and boost clocks are 5.00 GHz versus 4.30 GHz, respectively.

TDP ratings show a major split: AMD is rated at 45 W, Intel at 15 W. The AMD chip uses AMD Socket FP7, while Intel uses Intel BGA 1516. The release dates also differ, with AMD launching on 2024-04-15 and Intel on 2026-04-15.

Memory support, bus width, and bandwidth differ as described: DDR5 dual-channel at 89.6 GB/s for AMD versus DDR5 and LPDDR5X single-channel at 59.7 GB/s for Intel. ECC support is present on AMD but absent on Intel. PCIe lane counts are 20 for AMD and 6 for Intel, both Gen 4.

Cache layouts differ: AMD has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel has 192 KB L1 total, 2.5 MB L2 total, and 6 MB shared L3. The process nodes are 4 nm (TSMC) for AMD and 3 nm (Intel) for Intel.

Neither processor has an unlocked multiplier. The Intel part has a launch MSRP of $309. No launch MSRP is listed for the AMD part. The Intel part number is SAE3K, while the AMD part has two part numbers: 100-000001315 (FP7r2) and 100-000001388 (FP7).

Head-to-Head Benchmarks

The largest margin in the entire comparison appears in Cinebench R23 multi-core. The AMD Ryzen 5 PRO 8645HS scores 19,742 against 5,263 for the Intel Core 3 304, a 275.1% delta. This test heavily favors the AMD part's 12 threads and 45 W TDP, and the result indicates that sustained multi-core rendering is the AMD chip's strongest area.

PassMark integer math shows a 195.2% delta, with AMD at 72,740 and Intel at 24,640. Random string sorting follows at 159.7% (35,472 versus 13,659), and data compression at 131.6% (265,826 versus 114,775). These three PassMark tests together suggest a consistent pattern: the AMD processor handles parallel integer workloads with roughly two to three times the throughput of the Intel chip.

Cinebench R15 multi-core shows a 134.3% delta (1,989 versus 849), while Cinebench R20 multi-core shows 99.3% (8,291 versus 4,160). PassMark multithread shows 102.7% (23,569 versus 11,625), and data encryption shows 104.5% (17,387 versus 8,501). Extended instructions show 119% (21,212 versus 9,686). All of these exceed the 100% threshold, meaning the AMD part more than doubles the Intel part in each case.

The smallest margins appear in single-threaded and lightly threaded tests. PassMark single thread shows a 6.8% delta (3,858 versus 3,614), and Cinebench R15 single-core shows 6.1% (280 versus 264). PassMark find prime numbers shows 7.4% (73 versus 68). These results indicate that for a single execution thread, the Intel Core 3 304 is competitive with the AMD part, trailing by only a small amount despite its much lower base clock and TDP.

Cinebench R20 single-core shows a 99.3% delta (1,170 versus 587), which stands out as an outlier compared to the other single-threaded results. The R23 single-core test shows a 57.9% delta (2,787 versus 1,765), and floating-point math shows 53% (45,481 versus 29,722). Physics shows 39.2% (1,208 versus 868).

The overall pattern is clear: the AMD Ryzen 5 PRO 8645HS dominates across the board, with its largest advantages in multi-core and integer-heavy workloads. The Intel Core 3 304 stays closest in single-threaded tests, where its higher boost clock relative to its base clock partially compensates for its lower core count and memory bandwidth. The data confirms a decisive performance separation, with the AMD part posting an average benchmark score of 30,879 against 13,745 for the Intel chip, a difference of roughly 17,134 points in the aggregate.
