AMD Ryzen 5 8640U vs Intel Core i7-1370P Comparison

Head-to-Head Benchmarks

The benchmark data presents a closely contested matchup between the Intel Core i7-1370P and the AMD Ryzen 5 8640U, with Intel securing 8 wins and AMD taking 7 in the head-to-head tests. The most dramatic divergence appears in multi-core rendering workloads. In Cinebench R23 multi-core, the Intel part scores 16,365 against AMD's 10,433, a 56.9% advantage for Intel. This is the single largest delta in the entire comparison and reflects the substantial core-count difference between the two processors.

However, the Cinebench R15 multi-core test tells a different story. Here, AMD edges out Intel with a score of 1,663 versus 1,649, a margin of just 0.8%. This inconsistency between R15 and R23 results suggests that the two processors scale differently depending on the workload's threading characteristics and duration. The R23 result, being a longer and more demanding workload, likely favors Intel's higher thread count of 20 versus AMD's 12.

Single-core performance shows a similar split. In Cinebench R23 single-core, Intel leads with 2,310 points against AMD's 1,651, a 39.9% advantage. Yet in Cinebench R15 single-core, AMD wins with 256 points versus Intel's 232, a 9.4% lead. This reversal is noteworthy, as it indicates that AMD's Zen 4 architecture has a clear edge in shorter, lower-intensity single-threaded bursts, while Intel's Raptor Lake architecture pulls ahead when the workload extends over a longer duration.

The PassMark suite reveals a more balanced picture. In integer math, Intel wins decisively with 78,675 versus 68,051, a 15.6% margin. Floating-point math also goes to Intel by a wide margin: 54,105 versus 40,330, a 34.2% advantage. The prime number finding test shows Intel with 97 points versus AMD's 69, a 40.6% lead, and the physics test goes to Intel with 1,466 versus 1,033, a 41.9% margin.

AMD strikes back in several specialized PassMark tests. Extended instructions go to AMD with 16,500 versus 12,822, a 22.3% lead. Random string sorting favors AMD with 28,066 versus 23,580, a 16% advantage. Data compression and encryption also go to AMD, with scores of 230,080 versus 217,676 (5.4% lead) and 14,013 versus 13,067 (6.8% lead), respectively.

The overall multithread score is almost a dead heat. AMD scores 20,322 against Intel's 20,303, a difference of just 0.1%. Similarly, in single-thread PassMark, Intel wins by a razor-thin margin: 3,557 versus 3,534, a 0.7% lead. The passmark_singlethread test repeats this identical result, confirming consistency in that measurement.

Where Each One Wins

The data indicates that the Intel Core i7-1370P is the preferred choice for compute-heavy, multi-threaded rendering and number-crunching tasks. Its 56.9% lead in Cinebench R23 multi-core and 39.9% lead in R23 single-core make it the stronger option for content creation, 3D rendering, and CPU-bound professional applications that sustain high load over extended periods. The 34.2% advantage in floating-point math further reinforces this, as that metric often correlates with scientific computing, financial modeling, and physics simulations. The 41.9% win in PassMark physics also points to an edge in gaming physics calculations and similar real-time simulations.

Conversely, the AMD Ryzen 5 8640U demonstrates superiority in memory-access-heavy and data-movement tasks. The 22.3% lead in extended instructions suggests better optimization for AVX-512 or similar wide vector workloads, which benefit from AMD's Zen 4 design. The 16% advantage in random string sorting indicates faster memory access patterns, likely aided by the Zen 4 memory subsystem. Data compression and encryption wins, at 5.4% and 6.8% respectively, make the AMD part the better fit for file archiving, database operations, and VPN or disk encryption scenarios.

For single-threaded responsiveness in short bursts, the Cinebench R15 single-core result gives AMD a 9.4% edge, which could translate to snappier application launch times and lower-latency interactions in lighter workloads. However, the PassMark single-thread score favors Intel by 0.7%, so the real-world difference in everyday use is likely minimal.

The near-identical multithread scores (0.1% apart) and passmark_single_thread scores (0.7% apart) suggest that for many general-purpose multi-tasking scenarios, users would be hard-pressed to notice a performance difference between the two without running specialized benchmarks.

Architecture Differences

The Intel Core i7-1370P is built on Raptor Lake architecture, specifically the Raptor Lake-P variant, using Intel's 10 nm process node. It houses 14 cores and 20 threads, a configuration that relies on Intel's hybrid design combining performance and efficiency cores. The die size is 217 mm². The L1 cache is 80 KB per core, L2 is 2 MB per core, and L3 is 24 MB shared. The integrated graphics are Iris Xe Graphics with 96 execution units.

The AMD Ryzen 5 8640U is based on Zen 4 architecture under the Hawk Point codename, manufactured by TSMC on a 4 nm process. It features 6 cores and 12 threads, all based on a unified core design. The die size is 178 mm², and the chip integrates 25,000 million transistors. Cache allocations are smaller per core: L1 is 64 KB per core, L2 is 1 MB per core, and L3 is 16 MB shared. The integrated graphics are Radeon 760M.

The process node difference is substantial: Intel uses 10 nm while AMD uses 4 nm from TSMC. This explains part of the efficiency and density advantage for AMD, despite the smaller cache and fewer cores. The transistor count for AMD is listed at 25,000 million, while Intel's transistor count is not recorded in the database. The die size difference (217 mm² for Intel versus 178 mm² for AMD) is relatively modest given the core count disparity.
