AMD Ryzen 5 40 vs Intel Core i7-10850H Comparison

The Intel Core i7-10850H and AMD Ryzen 5 40 represent two distinct approaches to mobile computing, separated by process technology, core counts, and design goals. The data reveals a decisive performance gap in most multi-threaded and compute-intensive workloads, but the AMD part counters with significant wins in specific scenarios and efficiency metrics. This analysis breaks down the benchmark results, architectural differences, and the practical implications for different user profiles.

Head-to-Head Benchmarks

The head-to-head results are overwhelmingly lopsided in favor of the Intel Core i7-10850H, which claims victory in 13 of the 15 compared tests. The most dramatic disparity appears in multi-core rendering workloads. In Cinebench R23 multi-core, the Intel part scores 9,786 versus 4,841 for the AMD Ryzen 5 40, a massive 102.1% advantage. This effectively doubles the AMD processor's output in this heavily threaded test, reflecting the Intel chip's superior core count (6 vs 4) and thread count (12 vs 8).

The Intel lead extends to nearly every PassMark compute benchmark. The find prime numbers test shows Intel at 41 versus AMD's 20, a 105% delta. Floating point math also heavily favors Intel, with a score of 25,216 against AMD's 15,194, representing a 66% advantage. Physics simulation follows a similar pattern, with Intel scoring 718 versus AMD's 432, a 66.2% lead. Extended instruction workloads show a 61.3% gap (10,381 vs 6,437), and random string sorting sees Intel ahead by 42.4% (21,537 vs 15,124).

However, the AMD Ryzen 5 40 is not without its moments. The single-core Cinebench R15 test is a clear win for AMD, scoring 165.5 versus Intel's 139, a 16% improvement. This is notable given the Intel part's higher boost clock of 5.10 GHz versus AMD's 4.30 GHz, suggesting AMD's Zen 2 architecture delivers higher instructions per clock in this legacy test. The most significant AMD victory comes in the PassMark data encryption benchmark, where it scores 6,646 versus Intel's 3,890, a 41.5% margin. This indicates the AMD chip's cryptographic instruction set or memory subsystem provides a distinct advantage in encryption workloads.

In other multi-threaded tests, the Intel lead remains substantial but less extreme. Cinebench R15 multi-core shows Intel at 986 versus AMD's 790, a 24.8% delta. PassMark multi-thread scoring puts Intel at 11,643 versus 9,341, a 24.6% lead. Integer math sees Intel ahead by 26.3% (39,919 vs 31,598), and data compression shows a 17.2% advantage (165,882 vs 141,533). The closest single-threaded contest is in PassMark single thread, where Intel scores 2,668 versus AMD's 2,477, only a 7.7% difference.

The Verdict

The benchmark data paints a clear picture for workload prioritization. The Intel Core i7-10850H is the definitive choice for users whose primary tasks involve multi-core rendering, video encoding, scientific computing, or any CPU-bound work that scales with core count. Its 102.1% lead in Cinebench R23 multi-core is not incremental; it is transformative. The consistent 60-70% advantages in floating-point math, physics, and extended instructions make it the superior processor for professional content creation and engineering simulations.

The AMD Ryzen 5 40 carves out a narrower but valid niche. Its 41.5% advantage in data encryption makes it the better option for workloads involving heavy cryptographic operations, such as secure communications or data protection tasks. The 16% win in Cinebench R15 single-core also suggests potential advantages in lightly threaded legacy applications, though this does not carry over to the R23 single-core test where Intel leads by 20.1%.

For general-purpose mobile computing, the data favors Intel across the board in raw performance. The AMD part's 15W TDP compared to Intel's 45W TDP suggests superior power efficiency, but the benchmark scores do not reflect a performance-per-watt win in the measured tests—Intel simply outperforms. Users requiring maximum compute throughput should select the Intel Core i7-10850H. Users with encryption-heavy workloads or a strict need for lower power consumption should consider the AMD Ryzen 5 40, accepting the significant multi-core trade-off.

Specification Differences

The two processors differ significantly in their core specifications. The Intel Core i7-10850H features 6 cores and 12 threads, while the AMD Ryzen 5 40 is configured with 4 cores and 8 threads. Clock speeds also diverge: Intel offers a base clock of 2.70 GHz and a boost clock of 5.10 GHz, whereas AMD provides a higher base of 2.80 GHz but a lower boost of 4.30 GHz. Thermal design power is a major differentiator—Intel is rated at 45W, while AMD is rated at just 15W.

Memory support reflects their different target platforms. The Intel chip uses a dual-channel DDR4 interface with a peak bandwidth of 46.9 GB/s. The AMD chip uses dual-channel LPDDR5, delivering a substantially higher memory bandwidth of 88.0 GB/s. PCIe connectivity also differs: Intel provides 16 PCIe Gen 3 lanes (CPU only), while AMD provides only 4 PCIe Gen 3 lanes (CPU only).

Cache hierarchies are distinct. Both allocate 64 KB of L1 cache per core, but the L2 cache differs—Intel has 256 KB per core, while AMD doubles this to 512 KB per core. The shared L3 cache is heavily in Intel's favor: 12 MB shared versus 4 MB shared for AMD. Socket compatibility also diverges, with Intel using BGA 1440 and AMD using Socket FT6. The integrated graphics are different (UHD Graphics for Intel, Radeon 610M for AMD), and neither processor has an unlocked multiplier.

Architecture Differences

The architectural divide is fundamental. The Intel Core i7-10850H is built on Intel's Comet Lake architecture (Comet Lake-H), manufactured on a 14 nm process at Intel's own foundry. The AMD Ryzen 5 40 uses AMD's Zen 2 architecture under the Mendocino codename, fabricated on a 6 nm process at TSMC. This process node difference is significant, with AMD holding a substantial manufacturing advantage that contributes to its much lower 15W TDP.

The die sizes reflect the process and design differences. The AMD chip has a die size of 100 mm², while the Intel chip's die size is not specified. This smaller die, combined with the more advanced 6 nm process, allows AMD to achieve its power efficiency targets despite having fewer cores.

Core generation also differs: Intel's part is from the Core i7 (Comet Lake-H) generation, released in April 2020, while the AMD part belongs to the Ryzen 5 (Zen 2 Mendocino) generation, with a release date of September 2025. The architectural approach to cache and memory is also distinct—AMD pairs a smaller L3 cache (4 MB) with larger per-core L2 cache (512 KB) and faster LPDDR5 memory, while Intel relies on a larger shared L3 cache (12 MB) with slower DDR4 memory but a higher boost clock. These choices lead to the observed performance profile: Intel dominates in multi-threaded and compute-heavy tasks, while AMD excels in encryption and legacy single-core tests.
