Architecture Differences

The Intel Core 7 240H is built on Raptor Lake architecture, specifically the Raptor Lake-H refresh, and is fabricated on Intel's 10 nm process. It features a hybrid layout with 10 cores and 16 threads. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a shared 24 MB L3 pool.

The AMD Ryzen 5 PRO 8645HS belongs to the 8000 series and uses the Zen 4 architecture under the Hawk Point codename. It is manufactured on TSMC's 4 nm node, with 25,000 million transistors on a 178 mm² die. It has 6 cores and 12 threads. Cache amounts are 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3.

Memory support differs significantly. Intel supports both DDR4 and DDR5 in a dual-channel configuration. AMD supports only DDR5, also dual-channel, with a rated memory bandwidth of 89.6 GB/s. The AMD chip includes ECC memory support, a feature absent from the Intel part.

PCIe connectivity is another differentiator. Intel provides Gen 5 with 8 lanes (CPU only), while AMD offers Gen 4 with 20 lanes (CPU only). Integrated graphics are the Iris Xe Graphics 64EU on Intel and the Radeon 760M on AMD. Both use different sockets: Intel BGA 1744 versus AMD Socket FP7. The AMD part lists two part numbers (100-000001315 for FP7r2 and 100-000001388 for FP7).

Where Each One Wins

The Intel Core 7 240H is the clear leader in integer-heavy and physics-based workloads. It dominates in PassMark physics with a 42.6% advantage, and in prime number finding with a 39.7% lead. Floating point math is also strongly in Intel's favor, with a 29.5% edge. Integer math is 10.5% faster. In multithreaded PassMark, Intel is 1.7% ahead, and it wins data compression by 2.2%.

Cinebench results for Intel show a mixed picture. It wins R15 multicore by 18.7%, R20 multicore by 3.3%, and R20 singlecore by 3.2%. However, its R23 scores are lower than AMD's.

The AMD Ryzen 5 PRO 8645HS excels in single-threaded and instruction-heavy tasks. Its Cinebench R23 singlecore score is 38.3% higher than Intel's, and R23 multicore is 20.1% higher. In PassMark, it wins extended instructions by 20.3%, data encryption by 12.8%, and random string sorting by 18.6%. Single thread PassMark is 2% faster for AMD. It also wins Cinebench R15 singlecore by 11.1%.

For general productivity, the choice depends on software. If the workload uses AVX-512 or similar extended instructions, AMD is stronger. If the app scales with core count and integer math, Intel is the better choice.

Head-to-Head Benchmarks

The largest Intel wins come in physics and math tests. In PassMark physics, Intel scores 1723 versus AMD's 1208, a 42.6% advantage. For prime number finding, Intel records 102 against AMD's 73, a 39.7% lead. Floating point math shows 58905 for Intel and 45481 for AMD, a 29.5% margin. Integer math is 80396 versus 72740, a 10.5% win for Intel.

In Cinebench R15 multicore, Intel posts 2360 over AMD's 1989, an 18.7% difference. R20 multicore is closer: 8562 versus 8291, a 3.3% lead. R20 singlecore goes to Intel as well, 1208 to 1170, a 3.2% edge. PassMark multithread is nearly tied, with Intel ahead by only 1.7% (23975 vs 23569). Data compression also favors Intel, 271774 to 265826, a 2.2% improvement.

The AMD chip dominates the newer Cinebench R23 tests. In singlecore, AMD scores 2787 against Intel's 1719, a 38.3% edge. Multicore R23 is 19742 versus 15764, a 20.1% win for AMD. PassMark extended instructions show AMD ahead 21212 to 16897, a 20.3% margin. Random string sorting is 35472 for AMD versus 28866 for Intel, an 18.6% difference. Data encryption is also AMD-favored: 17387 versus 15155, a 12.8% win. Single-thread PassMark is a narrow AMD victory, 3858 to 3782, a 2% margin.

Overall, the Intel chip leads by total wins, 9 to 8. But the averages tell a different story. The Intel Core 7 240H has an average benchmark score of 31483, while the AMD Ryzen 5 PRO 8645HS averages 30879. Both are at the 82nd percentile of all CPUs. In the database, Intel sits close to the AMD Ryzen 9 5980HX and Intel Core Ultra 3 205, with a 0% delta. AMD's nearest rival is the AMD Ryzen 7 8700F with a 0.4% delta.
