Architecture Differences

The AMD Ryzen 5 PRO 8640U uses the Zen 4 architecture on TSMC's 4 nm process node, with the Hawk Point codename. The Intel Core 9 273PQE uses the Bartlett Lake codename on Intel's 10 nm process node. The AMD part integrates 25,000 million transistors on a 178 mm² die, while the Intel processor's transistor count and die size are not recorded in the database.

Core configurations differ substantially. The AMD chip provides 6 cores and 12 threads, while the Intel chip provides 12 cores and 24 threads. Cache hierarchies also diverge: AMD uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel uses 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Intel part thus has 125% more L3 cache (36 MB versus 16 MB) and double the L2 per core.

Memory support differs in scope. The AMD processor supports DDR5 only, while the Intel processor supports both DDR4 and DDR5. Both run dual-channel memory with identical 89.6 GB/s bandwidth and both support ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only).

Integrated graphics differ as well. The AMD chip uses the Radeon 760M, while the Intel chip uses UHD Graphics 770. The AMD part is a mobile processor on AMD Socket FP7, while the Intel part is a desktop processor on Intel Socket 1700.

Market positioning and release timing also differ. The AMD Ryzen 5 PRO 8640U launched on 2024-04-15 as an active mobile product. The Intel Core 9 273PQE launched on 2026-03-08 as an active desktop product. Neither has an unlocked multiplier.

The Verdict

The benchmark data presents a clear hierarchy: the Intel Core 9 273PQE dominates every recorded test. Its 12 cores and 24 threads, combined with a 5.90 GHz boost clock and 36 MB of L3 cache, produce an average score more than double that of the AMD chip. The Intel part's 93rd percentile placement confirms it competes near the top of the database, alongside the AMD Ryzen 9 7950X3D and Intel Core Ultra 5 250K Plus.

The AMD Ryzen 5 PRO 8640U, by contrast, sits in the 81st percentile, tied with older desktop parts like the AMD Ryzen 7 2700X and mobile chips like the AMD Ryzen 7 7736U. Its 28 W TDP and 4 nm process indicate a power-efficient mobile design, but the recorded performance does not approach the Intel part's output.

For workloads requiring maximum multi-threaded throughput, the Intel Core 9 273PQE is the clear choice from this data. For scenarios where the AMD chip's mobile form factor and lower TDP matter more than raw score, the 8640U retains a niche. The data does not support any conclusion favoring the AMD part on performance grounds.

Head-to-Head Benchmarks

The Intel Core 9 273PQE wins all 17 recorded comparisons. The largest margins appear in compute-heavy workloads. In PassMark floating-point math, Intel scores 125546 versus 45265 for AMD, a -63.9% delta. PassMark find prime numbers shows Intel at 198 versus 78, a -60.6% delta. PassMark physics records Intel at 2754 versus 1154, a -58.1% delta. PassMark data compression shows Intel at 585752 versus 260925, a -55.5% delta.

The Cinebench suite confirms the pattern. Across R15, R20, and R23, both single-core and multi-core tests show a consistent -49% delta. For example, Cinebench R23 multi-core scores 39190 for Intel and 19982 for AMD. Cinebench R23 single-core scores 5532 for Intel and 2821 for AMD. The identical -49% delta across all six Cinebench tests indicates a proportional scaling difference rather than a workload-specific advantage.

PassMark integer math shows Intel at 164629 versus 74875 for AMD, a -54.5% delta. PassMark extended instructions records Intel at 38743 versus 19130, a -50.6% delta. PassMark multithread shows Intel at 46107 versus 22795, also a -50.6% delta. PassMark data encryption records Intel at 29636 versus 15843, a -46.5% delta.

The smallest margin appears in single-threaded tests. PassMark single-thread scores 4573 for Intel and 3732 for AMD, a -18.4% delta. PassMark random string sorting shows Intel at 53167 versus 32114, a -39.6% delta, the second-smallest gap. These two results suggest the AMD chip's single-core efficiency partially compensates for its lower core count, though not enough to overtake Intel in any test.

Where Each One Wins

The Intel Core 9 273PQE wins every recorded benchmark category. Its largest advantages appear in floating-point math, prime number finding, and physics simulations, where the delta exceeds -58%. These results indicate strengths in scientific computing, numerical analysis, and simulation workloads. The Cinebench results, with a uniform -49% delta, confirm consistent multi-threaded scaling across rendering tasks.

The Intel part also leads in data compression and integer math, with deltas of -55.5% and -54.5% respectively. These results point to advantages in database operations, file archiving, and general productivity software. The PassMark multithread score of 46107 versus 22795 reinforces the Intel part's suitability for heavily parallel workloads.

The AMD Ryzen 5 PRO 8640U's closest performance comes in single-threaded tasks. The -18.4% delta in PassMark single-thread shows the smallest gap, suggesting the Zen 4 architecture delivers competitive per-core performance despite the lower boost clock (4.90 GHz versus 5.90 GHz). The random string sorting test, at -39.6%, also shows a relatively smaller gap, indicating the AMD chip handles memory-bound or latency-sensitive operations more efficiently relative to its overall score.

However, the AMD part's wins are not performance-based in the recorded data. Its advantages lie in physical specifications: a 28 W TDP versus 125 W, a 4 nm process versus 10 nm, and a mobile form factor on AMD Socket FP7. The database shows no benchmark category where the AMD chip outperforms the Intel part. For mobile deployments requiring lower power draw, the 8640U remains relevant, but for raw compute performance, the Intel Core 9 273PQE leads in every measured category.
