Where Each One Wins

The AMD Ryzen 7 7840U dominates the head-to-head record with 14 wins out of 15 benchmark comparisons. Its victories span nearly every category: multi-threaded rendering, compression, encryption, extended instruction sets, prime number finding, floating-point math, integer math, physics simulation, and random string sorting. The only benchmark where Intel takes the win is Cinebench R23 single-core, where the Core 5 210H manages a 5.6% edge. This pattern suggests the AMD chip is broadly stronger across compute-heavy workloads, particularly those that leverage many threads or vectorized instructions.

For users prioritizing raw multi-core throughput, the AMD part is the clear choice. Its wins in PassMark multithread (24782 versus 18252, a 26.3% gap) and Cinebench R23 multi-core (12719 versus 11830, a 7% gap) indicate substantial advantages in rendering and parallel processing tasks. The AMD chip also excels in data-centric operations: data compression shows a 24.5% lead, integer math a 32.3% lead, and random string sorting a 30.5% lead. These are meaningful margins for workloads like database operations, file compression, or scientific computing.

The Intel side wins one specific test: Cinebench R23 single-core. This is a notable victory because it indicates that for lightly threaded applications, the Intel architecture can outperform the AMD part. However, the margin is modest at 5.6%, and the AMD chip counters with a slight lead in PassMark single-thread (0.7%). The Intel chip also holds its own in the closest comparison: PassMark single-thread where the difference is only 26 points (3539 versus 3565). For users running mostly single-threaded legacy applications, the Intel chip is not embarrassing, but the broader benchmark suite favors AMD.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Intel Core 5 210H is built on Raptor Lake architecture, specifically the Raptor Lake-H refresh, and manufactured on Intel's 10 nm process at Intel's own foundry. The AMD Ryzen 7 7840U uses Zen 4 architecture under the Phoenix codename, fabricated by TSMC on a 4 nm process. This process advantage is significant: the AMD chip packs 25,000 million transistors into a 178 mm² die, whereas Intel's transistor count and die size are not recorded in the database.

The core layouts differ as well. Both have 8 physical cores, but the Intel part has 12 threads versus AMD's 16 threads. This implies the Intel chip uses a hybrid arrangement with fewer hyper-threaded cores, likely a mix of performance and efficiency cores, while the AMD chip has all 8 cores capable of simultaneous multi-threading. The cache hierarchy also reflects different strategies: Intel allocates 80 KB L1 and 2 MB L2 per core, while AMD uses 64 KB L1 and 1 MB L2 per core. However, AMD's shared L3 cache is larger at 16 MB versus Intel's 12 MB.

Memory support diverges sharply. The Intel chip supports both DDR4 and DDR5, while the AMD chip supports only DDR5. AMD also enables ECC memory support, which Intel does not. Memory bandwidth is listed for the AMD part at 89.6 GB/s, while Intel's figure is not recorded. PCIe connectivity also differs: Intel offers Gen 5 with 8 lanes (CPU only), while AMD provides Gen 4 with 20 lanes (CPU only). The integrated graphics are different as well: Intel uses Iris Xe Graphics with 48 execution units, while AMD employs the Radeon 780M.

Power envelopes are a major architectural differentiator. The Intel chip has a 45 W TDP, while the AMD chip is rated at 28 W. This is a substantial difference in thermal and power constraints, suggesting the AMD part is designed for more power-efficient mobile deployments, despite delivering higher benchmark scores in most tests.

The clock speed differential is notable: AMD starts at a higher base clock of 3.30 GHz versus Intel's 2.20 GHz, and boosts to 5.10 GHz versus Intel's 4.80 GHz. This partly explains AMD's benchmark dominance despite the Intel chip having a higher TDP allowance. The AMD chip also has a transistor count of 25,000 million and a die size of 178 mm², both of which are recorded, while Intel's remain unspecified in the database.

Head-to-Head Benchmarks

The head-to-head data tells a one-sided story. In Cinebench R15 multi-core, the AMD Ryzen 7 7840U scores 1990 against Intel's 1757, an 11.7% advantage. Single-core in R15 also favors AMD: 264 versus 247, a 6.4% gap. Moving to Cinebench R23, AMD extends its multi-core lead with 12719 versus 11830, a 7% difference, but Intel wins the single-core round with 1771 versus 1677.5, a 5.6% margin.

The PassMark suite reveals the most dramatic separations. Data compression: AMD scores 288604 versus 217805, a 24.5% lead. Data encryption: AMD scores 17691 versus 12187, a 31.1% lead. Extended instructions: AMD scores 20432 versus 13370, a 34.6% lead. Prime number finding: AMD scores 80 versus 53, a 33.7% lead. Floating-point math: AMD scores 51767 versus 45057, a 13% lead. Integer math: AMD scores 90852 versus 61503, a 32.3% lead. Multithread: AMD scores 24782 versus 18252, a 26.3% lead. Physics: AMD scores 1256 versus 1040, a 17.2% lead. Random string sorting: AMD scores 33757 versus 23451, a 30.5% lead.

The only PassMark category where AMD does not decisively win is single-thread, where it scores 3565 versus Intel's 3539, a 0.7% difference. This is within noise territory, but it counts as a win for AMD in the database. The overall tally is 14 wins for AMD and 1 for Intel, with the single Intel victory being the Cinebench R23 single-core test.

The Verdict

The data points to a clear overall winner: the AMD Ryzen 7 7840U outperforms the Intel Core 5 210H in nearly every measured benchmark. The AMD chip leads in multi-core rendering, data processing, encryption, math operations, and physics simulation, often by double-digit percentages. Its 16 threads versus Intel's 12 threads give it a structural advantage in parallel workloads, and its higher base and boost clocks (3.30 GHz and 5.10 GHz versus 2.20 GHz and 4.80 GHz) reinforce that advantage.

The Intel Core 5 210H wins exactly one benchmark: Cinebench R23 single-core, where it leads by 5.6%. This suggests that for applications that are strictly single-threaded and not heavily dependent on cache or memory bandwidth, the Intel chip can compete. However, even in the single-thread PassMark test, AMD holds a slight edge. The Intel chip also supports DDR4 memory, which could be relevant for systems using older memory modules, and it offers PCIe Gen 5 connectivity, though with fewer lanes than AMD's Gen 4 implementation.

For most users, the AMD Ryzen 7 7840U is the more capable processor. It delivers higher scores across the board while operating at a lower TDP of 28 W versus Intel's 45 W, which suggests better performance-per-watt for mobile applications. The Intel chip does have a recorded launch MSRP of $342, while AMD's pricing is not listed, but the benchmark data alone favors AMD. The single-core Cinebench win for Intel is an interesting anomaly, but it does not outweigh the 14-1 record in the head-to-head comparisons. Users needing maximum multi-threaded performance, encryption throughput, or data compression speed should choose the AMD part. Users running only lightly threaded applications might notice Intel's single-core edge, but the difference is small and limited to one test.
