AMD Ryzen 9 7940H

The AMD Ryzen 9 7940H sits in the 91st percentile of all CPUs benchmarked, a position that places it firmly in the upper tier of mobile processors. Its average benchmark score of 40,431 is remarkably close to its nearest rivals, with deltas of less than 1.1% in every direction. This is a chip that trades blows with desktop-class parts and the best of the mobile field, rather than one that runs away from them. The data shows a processor with exceptional balance, where single-threaded responsiveness and multi-threaded throughput are both top-tier, making it a versatile choice for demanding mobile workloads.

Benchmark Performance

The Ryzen 9 7940H delivers its strongest showing in multi-threaded rendering workloads. In Cinebench R23, it scores 24,703 points in the multi-core test, a figure that places it just 0.7% behind the Intel Core i9-13905H's aggregate score of 40,712. The Cinebench R20 multi-core result of 10,375 points reinforces this picture, as does the R15 multi-core score of 2,490. These numbers indicate that the 8-core, 16-thread Zen 4 design sustains high throughput under sustained load, a trait that is critical for video encoding, 3D rendering, and software compilation.

On the single-threaded front, the 7940H is equally impressive. Its Cinebench R23 single-core score of 3,487 points is a strong result, and the R20 single-core figure of 1,464 points confirms that the architecture's IPC gains are fully realized. The PassMark single-thread score of 3,952 further validates this, showing that the chip's 5.20 GHz boost clock is not just a marketing figure but a practical advantage in latency-sensitive tasks. This combination of high single-core and multi-core scores is rare in a 35W TDP part, and it gives the 7940H a flexibility that many rivals lack.

The PassMark suite reveals specific strengths. The integer math score of 101,977 and floating point math score of 62,057 are both substantial, indicating robust general-purpose compute performance. Data encryption is handled particularly well, with a score of 21,096, and extended instructions score 26,804, suggesting strong support for modern SIMD workloads. The data compression score of 352,077 is another highlight, making this a capable chip for archiving and file management tasks. The physics score of 1,300 and find prime numbers score of 81 are more modest, but they are not outliers in the context of the overall balanced profile. The multithread score of 29,063 rounds out the PassMark results, reinforcing the chip's position as a high-end mobile part.

How It Compares

The Ryzen 9 7940H’s nearest rival is the AMD Ryzen 7 7700, a desktop processor with an average score of 40,468. The 7940H trails this part by a negligible 0.1%, meaning the mobile chip effectively matches a desktop CPU from the same generation in aggregate benchmarks. This is a significant statement about the efficiency of the Phoenix architecture, as the 7940H achieves this parity within a 35W power envelope. The delta is so small that it falls within run-to-run variance, so the data suggests these two are functionally equivalent in overall performance.

Against the AMD Ryzen AI 9 365, the 7940H leads by 0.4%. The AI 9 365 has an average score of 40,262, and the 7940H’s advantage, while slim, is consistent. This places the 7940H ahead of a newer-generation AI-focused chip, which is notable given that the AI 9 365 includes a more advanced NPU. For users who prioritize raw CPU compute over AI acceleration, the 7940H holds its own and then some.

The Intel Core i9-13905H is the closest competitor, with an average score of 40,712. The 7940H trails this part by 0.7%, a margin that is slightly larger than the others but still within the same performance class. Both are high-end mobile parts, and the data indicates they are effectively interchangeable in aggregate performance. The 7940H’s advantage lies in its 4 nm process and integrated Radeon 780M graphics, which are not reflected in the CPU-only benchmark scores.

Finally, the Intel Core Ultra 5 235T trails the 7940H by 1.1%. The 235T has an average score of 39,995, and the 7940H’s lead is the largest among the four rivals. While the 235T is a lower-tier part in Intel’s lineup, the delta shows that the 7940H still maintains a clear edge over it in overall compute capability. The 7940H is not the fastest in this group, but it is never slower by more than 0.7%, and it leads two of the four rivals.

Power and Thermals

The Ryzen 9 7940H is rated for a TDP of 35W, which classifies it as a high-performance mobile part designed for thin-and-light gaming laptops and powerful ultrabooks. This TDP is the key to understanding its thermal behavior: it is not a desktop replacement part that requires a massive cooling solution, but it is also not an ultra-low-power chip for fanless designs. The data implies that a capable dual-fan cooling solution or a well-designed vapor chamber is sufficient to keep this chip within its thermal limits.

At 35W, the 7940H’s performance is even more impressive. The fact that it matches a desktop Ryzen 7 7700, which runs at a much higher TDP, indicates that the Zen 4 architecture on TSMC’s 4 nm process is exceptionally efficient. The 178 mm² die size and 25,000 million transistors are packed into a compact package, and the 89.6 GB/s of memory bandwidth from dual-channel DDR5 is enough to feed the 8 cores without bottlenecking. The 16 MB of shared L3 cache and 1 MB per-core L2 cache are also well-suited to this power class.

Cooling requirements are moderate for a gaming laptop. The 35W TDP means that a laptop with a decent thermal solution can sustain the chip’s boost clocks without excessive fan noise or throttling. Users should still expect some heat output under sustained multi-core loads, but the data does not suggest any exotic cooling needs. This is a chip that fits comfortably into the mainstream high-performance laptop segment, where manufacturers already design for similar TDPs.

Who Should Consider It

The Ryzen 9 7940H is a strong choice for content creators who need portable rendering power. The Cinebench R23 multi-core score of 24,703 is a clear indicator that this chip can handle 3D modeling, video editing, and photo batch processing without slowing down. The data compression score of 352,077 also makes it appealing for users who work with large archives or datasets, as compression tasks will complete quickly.

Gamers will find the 7940H compelling, though the integrated Radeon 780M graphics mean that it is best paired with a discrete GPU for modern titles. The high single-thread score of 3,952 in PassMark ensures that the CPU will not bottleneck a mid-range or high-end discrete graphics card, particularly in esports titles or games that are CPU-bound. The 91st percentile ranking also suggests that this chip will remain relevant for several years of gaming workloads.

Office and productivity users are well-served, but this chip is arguably overkill for basic tasks like word processing or spreadsheet work. The single-thread performance is excellent, which makes everyday tasks feel snappy, but the multi-core capabilities are wasted on such workloads. The data indicates that the 7940H is best purchased for users who know they will push it with demanding applications, rather than those who only need web browsing and email.

Single-Thread vs Multi-Thread Behavior

The Ryzen 9 7940H exhibits a balanced split between single-threaded and multi-threaded performance, which is its defining characteristic. The Cinebench R23 single-core score of 3,487 and multi-core score of 24,703 represent a ratio that shows strong scaling across the 8 cores. This is not a chip that sacrifices single-thread speed for multi-core throughput, nor one that relies on high boost clocks to compensate for weak core scaling.

In real workloads, this balance means that the 7940H excels at mixed usage patterns. A user can be editing a 4K video timeline (multi-threaded) while simultaneously browsing the web or using a word processor (single-threaded), and the chip will handle both with ease. The PassMark single-thread score of 3,952 ensures that user interface interactions and application launches remain responsive, while the multithread score of 29,063 guarantees that background tasks like rendering or exporting will complete without hogging all resources.

The data also shows that the chip’s boost clock of 5.20 GHz is effectively utilized. The single-thread scores are close to what one would expect from a desktop chip with a similar clock speed, indicating that the mobile power management does not cripple short-duration bursts. Conversely, the multi-core scores show that the 35W TDP is sufficient to maintain high clocks across all cores for longer workloads, even if the absolute frequencies may be lower than the single-core boost. This dual nature makes the 7940H a rare mobile part that does not force users to choose between responsiveness and throughput.
