AMD Ryzen 5 PRO 8640U vs Intel Core 7 350 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall advantage for the AMD Ryzen 5 PRO 8640U, which wins 12 of the 17 head-to-head comparisons. The Intel Core 7 350 takes 5 wins, but they are concentrated in specific single-threaded and specialized workloads.

The largest margin belongs to the AMD part in Cinebench R23 multi-core, where it scores 19982 against Intel's 8030, a 148.8% advantage. This is the clearest signal of the AMD processor's dominance when all cores are engaged. The Cinebench R20 multi-core test shows the same pattern, with AMD at 8392 versus Intel's 5373, a 56.2% gap. Even in Cinebench R15 multi-core, AMD leads 2014 to 1220, which is a 65.1% difference.

Integer math performance is another area of substantial AMD superiority. The PassMark integer math score for the Ryzen 5 PRO 8640U is 74875, compared to 33734 for the Core 7 350, a 122% lead. Data compression follows a similar trajectory: AMD scores 260925 against Intel's 143123, an 82.3% margin. Random string sorting shows AMD ahead by 86.3%, with scores of 32114 and 17238 respectively.

The AMD processor also wins in Cinebench R23 single-core, scoring 2821 against Intel's 2046, a 37.9% advantage. This result is notable because single-core performance is often a strong point for Intel parts, yet the data shows the Ryzen winning this round decisively. However, the Cinebench R15 single-core test tells a different story: Intel wins narrowly with 292 versus AMD's 284, a 2.7% edge. In Cinebench R20 single-core, AMD wins again with 1184 to 758, a 56.2% lead.

The Intel Core 7 350 claims its largest win in PassMark find prime numbers, scoring 107 against AMD's 78, a 27.1% advantage. This specialized mathematical workload clearly favors the Intel architecture. The Intel chip also wins PassMark single-threaded tests, scoring 4100 versus AMD's 3732, a 9% margin. PassMark physics is nearly even, with Intel at 1173 and AMD at 1154, a 1.6% difference.

Other PassMark sub-tests favor AMD. Floating point math: AMD scores 45265, Intel 42809, a 5.7% edge. Data encryption: AMD 15843, Intel 10933, a 44.9% lead. Extended instructions: AMD 19130, Intel 12045, a 58.8% gap. Multi-threaded PassMark: AMD 22795, Intel 15170, a 50.3% difference.

The overall average benchmark scores reflect this split: AMD sits at 30254, while Intel records 17779. The AMD processor places in the 81st percentile of all CPUs in the database, whereas the Intel chip lands in the 71st percentile. The nearest rivals for AMD include the AMD Ryzen 7 2700X (0.1% higher average score), the AMD Ryzen 7 7736U (0.4% lower), the AMD Ryzen 5 7640HS (0.4% lower), and the Intel Core i9-11980HK (0.6% lower). For Intel, the closest competitors are the Intel Core 5 221TE (0.5% lower), the AMD EPYC 9374F (0.5% higher), the AMD Ryzen 5 3600XT (0.6% lower), and the Intel Core 5 120U (0.7% lower).

The Verdict

The benchmark data indicates that the AMD Ryzen 5 PRO 8640U is the stronger processor for almost every compute-heavy task. Its multi-core performance is in a different class, with Cinebench R23 multi-core showing nearly 150% higher scores. The AMD chip also leads in single-core Cinebench tests, which suggests that its architecture is not just about core count but also about per-core efficiency.

The Intel Core 7 350 only wins where the workload is either highly specialized, as in prime number finding, or where the PassMark single-threaded metric reflects a specific optimization. The physics score is essentially tied. These wins are narrow and do not compensate for the large gaps in general productivity tasks.

From the data, the AMD processor is the choice for users who run multi-threaded applications such as video encoding, 3D rendering, or software compilation. The Intel chip may have a place in workloads that rely on prime number calculations or certain single-threaded integer operations, but those are niche scenarios. The percentile ranking reinforces this: AMD at 81st versus Intel at 71st places the Ryzen clearly ahead in the overall distribution.

Architecture Differences

The AMD Ryzen 5 PRO 8640U uses the Zen 4 architecture under the Hawk Point codename, manufactured on a 4 nm process at TSMC. The Intel Core 7 350 uses the Wildcat Lake codename, built on a 3 nm process at Intel's own foundry. These are fundamentally different design approaches.

AMD implements simultaneous multithreading, providing 12 threads from 6 cores. Intel does not, offering only 6 threads from 6 cores. This thread count difference is a major factor in the multi-core benchmark results. The AMD processor also has a larger L3 cache at 16 MB shared, while Intel provides 6 MB shared. Per-core L1 cache differs: AMD has 64 KB per core, Intel has 192 KB per core. L2 cache is 1 MB per core for AMD and 2.5 MB per core for Intel.

The AMD processor supports ECC memory, while the Intel chip does not. AMD uses a dual-channel memory bus with DDR5 memory, achieving 89.6 GB/s of bandwidth. Intel also supports DDR5 but adds LPDDR5X, yet operates on a single-channel memory bus with 59.7 GB/s. This memory bandwidth gap likely contributes to AMD's wins in data compression and encryption tests.

PCIe connectivity differs: AMD provides Gen 4 with 20 lanes, Intel provides Gen 4 with 6 lanes. Integrated graphics also differ: AMD uses the Radeon 760M, while Intel uses Xe3 Graphics with 2 Xe cores. The AMD processor's transistor count is 25,000 million on a 178 mm² die, while the Intel chip's transistor count and die size are not recorded in the database.

Specification Differences

The base clock rates are markedly different. AMD runs at 3.50 GHz, Intel at 1.50 GHz. Boost clocks are closer: AMD at 4.90 GHz, Intel at 4.80 GHz. The thermal design power also separates them: AMD is rated at 28 W, Intel at 15 W. This suggests Intel targets lower power envelopes, which may explain its narrower wins in some single-threaded tests.

The socket types are incompatible: AMD uses AMD Socket FP7, Intel uses Intel BGA 1516. Memory support is another differentiator: AMD lists DDR5, Intel lists DDR5 and LPDDR5X. ECC memory is present on AMD, absent on Intel. PCIe lane counts differ as noted, and the integrated GPU models are different. The release dates are also distinct: AMD launched on 2024-04-15, Intel on 2026-04-15. The Intel processor has a launch MSRP of $469, while AMD has no recorded launch MSRP.

Where Each One Wins

The AMD Ryzen 5 PRO 8640U wins in 12 benchmark categories, covering the majority of general-purpose and compute-intensive workloads. Its multi-core Cinebench results, integer math, data compression, random string sorting, data encryption, and extended instructions all show substantial leads. The floating point math advantage is smaller but still favors AMD. For users running rendering, encoding, compression, or database workloads, the data clearly points to the AMD processor.

The Intel Core 7 350 wins in 5 categories, but these are narrower and more specialized. The prime number finding test shows a 27.1% lead, which is the largest Intel advantage. The PassMark single-threaded tests show a 9% lead, and the Cinebench R15 single-core and PassMark physics wins are marginal at 2.7% and 1.6% respectively. These results suggest Intel's architecture has specific strengths in single-threaded integer operations and simple physics calculations, but these do not translate into broad performance superiority.

The overall average benchmark score confirms the split: AMD at 30254 versus Intel at 17779. The AMD processor's nearest rival list includes the Intel Core i9-11980HK, which is only 0.6% behind, indicating that the Ryzen 5 PRO 8640U competes with much higher-tier Intel parts. The Intel Core 7 350's nearest rivals include the AMD Ryzen 5 3600XT, which is 0.6% ahead, showing that it sits in a lower performance bracket. The data supports the AMD processor as the more capable chip for almost all tasks, with the Intel chip offering targeted advantages in niche workloads.
