AMD Ryzen 7 PRO 6850HS vs Intel Core i9-13900H Comparison

The Intel Core i9-13900H and AMD Ryzen 7 PRO 6850HS are both high-end mobile processors aimed at thin-and-light performance laptops, but benchmark results show they are not chasing the same target. The Intel part wins the majority of head-to-head comparisons, yet the AMD chip secures the two most important wins in modern multi-threaded and single-threaded workloads. The data shows a clear split: Intel dominates older and specialized compute tests, while AMD takes the lead in the Cinebench R23 suite, which is often the best predictor of sustained all-core rendering performance. With 15 benchmark wins for the Intel chip and only 2 for the AMD chip, the raw scoreboard favors Intel, but the magnitude of AMD’s victories in those two tests is substantial enough to flip the practical recommendation for certain users.

Head-to-Head Benchmarks

The most decisive Intel victory comes in the PassMark find prime numbers test, where it scores 104 against AMD’s 58, a 79.3% advantage. This is a synthetic workload that heavily favors Intel’s architecture and shows the largest performance gap between the two chips. Similarly, in PassMark physics, Intel leads with 1745 points versus 1065, a 63.8% difference, suggesting that the Intel chip has a significant edge in simulated physics calculations. Floating point math also goes strongly to Intel, with a score of 69611 compared to AMD’s 46706, a 49% lead. These results indicate that for scientific computing, engineering simulations, or any workload that relies heavily on FPU throughput, the Intel Core i9-13900H is the clear choice.

In the older Cinebench R15 multi-core test, Intel wins with 2666.5 points against AMD’s 1913, a 39.4% lead. The gap narrows in the newer Cinebench R20 multi-core test, where Intel scores 9676 versus AMD’s 7971, a 21.4% advantage. Intel also leads in Cinebench R20 single-core with 1365 points against AMD’s 1125, a 21.3% gain. The PassMark multithread test shows Intel ahead by 23.9%, with a score of 27673 versus 22330. These consistent wins across multiple generations of the Cinebench suite and PassMark’s multithread test suggest that Intel’s higher core count and thread count provide a real advantage in traditional multi-threaded applications, even if the margin shrinks in newer tests.

However, the story changes dramatically in Cinebench R23. The AMD Ryzen 7 PRO 6850HS wins the multi-core test with a score of 18980, beating Intel’s 17471 by 8%. More impressively, AMD wins the single-core test by a massive 26.7%, scoring 2679 against Intel’s 1964.5. This is a surprising result because Intel wins the Cinebench R20 single-core test by 21.3%, yet loses the R23 single-core test by nearly the same margin in the opposite direction. The data suggests that AMD’s Zen 3+ architecture scales better with the R23 workload’s AVX-512-like instructions, which are known to be particularly strong on AMD cores. For users who primarily run Cinebench R23 as their benchmark of choice, the AMD chip is the better performer.

Other PassMark tests show Intel maintaining a lead, but with varying margins. Data compression goes to Intel with 326425 points versus AMD’s 272838, a 19.6% lead. Integer math is closer, with Intel scoring 97159 against AMD’s 85459, a 13.7% advantage. Random string sorting also favors Intel by 24.2%, with a score of 35637 versus 28693. Data encryption shows Intel ahead by 9.4%, scoring 18974 against 17350. Extended instructions follow a similar pattern, with Intel winning by 6.8%, scoring 19330 versus 18091. These results paint a picture of Intel having a broad but sometimes modest advantage in general-purpose computing tasks, while AMD’s wins are concentrated in the specific R23 workload.

The Verdict

Choose the Intel Core i9-13900H if your primary workload involves legacy or specialized applications. The data shows it is significantly ahead in physics simulations, floating point math, and prime number calculations, with margins ranging from 49% to 79.3%. It also leads in the older Cinebench R15 and R20 tests, making it a safer bet for software that has not been updated to take advantage of the newest instruction sets. The Intel chip wins 15 of 17 head-to-head comparisons, and its average benchmark score of 28886 is slightly higher than AMD’s 28549, placing it in the 81st percentile versus AMD’s 80th. For users who need consistent performance across a wide variety of tasks, the Intel chip is the more reliable choice.

Choose the AMD Ryzen 7 PRO 6850HS if your work is dominated by Cinebench R23 rendering. The AMD chip wins that multi-core test by 8% and the single-core test by 26.7%, which are the most relevant scores for 3D artists and video editors who rely on Cinebench as their standard benchmark. Despite losing the majority of other tests, the magnitude of AMD’s wins in R23 suggests that its architecture is better optimized for the specific instruction mix used in modern rendering engines. The AMD chip also has a lower TDP of 35W versus Intel’s 45W, which may translate to better battery life and thermal behavior in thin laptops. However, the data does not show a clear overall performance winner, so the choice comes down to which benchmark matters most to you.

Architecture Differences

The Intel Core i9-13900H is built on Raptor Lake architecture, using a 10nm process node from Intel’s own foundry. It has 14 cores and 20 threads, with a base clock of 2.60 GHz and a boost clock of 5.40 GHz. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The die size is 257 mm². In contrast, the AMD Ryzen 7 PRO 6850HS uses Zen 3+ architecture, codenamed Rembrandt, on a 6nm process node from TSMC. It has 8 cores and 16 threads, with a base clock of 3.20 GHz and a boost clock of 4.70 GHz. The cache is smaller, with 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The die size is 208 mm².

These architectural differences explain the benchmark results. Intel’s higher core count and larger L3 cache give it an advantage in multi-threaded workloads that scale well across cores, such as the PassMark multithread test and Cinebench R15. AMD’s smaller core count but higher base clock and more efficient 6nm process allow it to achieve competitive single-thread performance, which is evident in the Cinebench R23 single-core test. The Intel chip supports DDR4 and DDR5 memory, while the AMD chip supports only DDR5, but both use a dual-channel memory bus. The AMD chip has a higher memory bandwidth of 76.8 GB/s, which may contribute to its strong performance in memory-sensitive workloads like Cinebench R23.

Where Each One Wins

The Intel Core i9-13900H is the winner for users who prioritize computational throughput in legacy benchmarks and specialized math workloads. The data shows it leads by 79.3% in prime number finding, 63.8% in physics, and 49% in floating point math. It also wins the PassMark multithread test by 23.9% and the Cinebench R15 multi-core test by 39.4%. For users running older software, scientific simulations, or any application that relies on integer or floating point arithmetic, the Intel chip is the better choice. Its higher boost clock of 5.40 GHz also gives it an edge in lightly-threaded tasks that are not captured by the Cinebench R23 single-core test.

The AMD Ryzen 7 PRO 6850HS is the winner for users whose primary benchmark is Cinebench R23, which is the most common rendering benchmark in the industry. The AMD chip wins the R23 multi-core test by 8% and the single-core test by 26.7%, making it the better choice for 3D rendering, video encoding, and other creative workloads that use the same instruction mix. The AMD chip also has a lower TDP of 35W, which may make it more suitable for ultra-thin laptops where thermal headroom is limited. Additionally, the AMD chip supports PCIe Gen 4 with 20 lanes, which is more than Intel’s 8 lanes, potentially offering better connectivity for fast SSDs and external GPUs. For users who live in Cinebench R23, the AMD chip is the clear pick despite losing most other benchmarks.
