AMD Ryzen 5 7535U vs Intel Core i9-11900F Comparison

The Intel Core i9-11900F and AMD Ryzen 5 7535U occupy entirely different corners of the processor market, and the benchmark data makes that separation stark. The Intel part, a desktop Rocket Lake chip, wins all 17 head-to-head comparisons against the mobile Ryzen, with margins ranging from a modest 6.6% to a crushing 118.4%. While both CPUs sit at the 76th percentile of all processors, the average benchmark score of 23,254 for the i9-11900F versus 22,791 for the Ryzen 5 7535U indicates that the Intel chip is the stronger performer overall, but the data also reveals a significant efficiency story that favors the AMD part.

The Verdict

The data points to a clear performance hierarchy: the Intel Core i9-11900F is the outright winner in every measured benchmark, making it the choice for users who prioritize raw compute power above all else. Its dominance is particularly pronounced in multi-threaded workloads, where it leads by double-digit percentages across the board, and in single-threaded tasks where it maintains a consistent advantage. The Ryzen 5 7535U, meanwhile, never wins a single comparison, but its 28-watt TDP against the Intel chip’s 65-watt TDP suggests it is designed for a different purpose—sustained mobile operation where power draw and thermals matter more than peak performance. For a desktop user with a Socket 1200 motherboard seeking maximum processing throughput, the i9-11900F is the data-backed choice. For a laptop buyer or someone building a power-efficient system, the Ryzen 5 7535U’s integrated Radeon 660M graphics and active production status make it a more sensible pick, even if its benchmark scores trail. The data does not support picking the AMD part for performance reasons; it only supports picking it for platform and efficiency reasons.

Architecture Differences

The architectural divide between these two processors is substantial. The Intel Core i9-11900F uses the Rocket Lake architecture on a 14 nm process node fabricated by Intel, while the AMD Ryzen 5 7535U leverages the Zen 3+ architecture on a 6 nm node from TSMC. This process size difference is a major factor in the power and efficiency gap: the Intel chip has a 65-watt TDP, whereas the AMD part is rated at just 28 watts. The Intel processor packs 8 cores and 16 threads, compared to the Ryzen’s 6 cores and 12 threads. Both share the same 16 MB of shared L3 cache, but the per-core L1 cache differs—80 KB per core on the Intel versus 64 KB per core on the AMD. The L2 cache is identical at 512 KB per core. The foundry and node differences are stark: Intel’s 14 nm process is older and less dense than TSMC’s 6 nm, which helps explain the Ryzen’s lower power draw. The memory support also diverges, with the Intel chip using DDR4 while the AMD chip supports DDR5, and the memory bandwidth reflects this—51.2 GB/s for Intel versus 76.8 GB/s for AMD. The AMD part also includes integrated Radeon 660M graphics, while the Intel chip has none, and it supports ECC memory, which the Intel does not.

Head-to-Head Benchmarks

The benchmark results show a sweeping victory for the Intel Core i9-11900F, but the magnitude of the wins varies significantly by workload. The largest gap appears in Cinebench R23 multicore, where Intel scores 18,759 against AMD’s 8,591, a 118.4% advantage. This is a massive margin that speaks to the Intel chip’s superior multi-threading capability in sustained rendering tasks. The gap narrows considerably in single-threaded tests, though Intel still leads. In Cinebench R23 single-core, the i9-11900F scores 2,648 versus 1,414 for the Ryzen, an 87.3% lead. Geekbench multicore shows Intel ahead at 9,417 versus 6,466, a 45.6% difference, while Geekbench single-core has Intel at 2,220 versus 1,602, a 38.6% lead. The PassMark suite reveals a similar pattern. Integer math shows Intel scoring 83,718 against AMD’s 62,109, a 34.8% win, while floating-point math sees Intel at 48,562 versus 33,971, a 43% advantage. Data compression heavily favors Intel: 280,847 versus 200,252, a 40.2% margin. Random string sorting is another Intel win at 32,520 versus 21,267, a 52.9% lead. Extended instructions show Intel ahead at 19,443 versus 13,187, a 47.4% difference. The closest margins come in PassMark single-thread tests, where Intel scores 3,413 against AMD’s 3,203, a 6.6% lead, and in data encryption, where Intel scores 13,636 versus 12,706, a 7.3% edge. PassMark physics shows Intel at 949 versus 839, a 13.1% lead, and find prime numbers has Intel at 61 versus 50, a 22% advantage. The overall PassMark multithread score puts Intel at 22,115 versus 17,039, a 29.8% win.

Where Each One Wins

The Intel Core i9-11900F wins every benchmark category, but the nature of its wins suggests different use-case strengths. In multi-threaded workloads like Cinebench R23 multicore, the 118.4% lead over the Ryzen makes it the clear choice for video rendering, 3D modeling, and other heavily parallel tasks. The 45.6% Geekbench multicore advantage and 29.8% PassMark multithread lead reinforce this conclusion. The Intel chip also excels in memory-intensive operations like data compression, where its 40.2% margin shows strength in archiving and file management tasks. Floating-point math and extended instructions, with 43% and 47.4% leads respectively, point to scientific computing and engineering simulation workloads. The 34.8% integer math advantage suggests solid performance in general productivity and database operations. The AMD Ryzen 5 7535U, despite losing all benchmarks, has a clear use case in power-constrained environments. Its 28-watt TDP versus Intel’s 65 watts indicates it is built for laptops where battery life and thermal management are critical. The integrated Radeon 660M graphics mean it can handle basic display output without a discrete GPU, which the Intel chip cannot do. The AMD chip’s support for DDR5 memory and ECC memory also positions it for more modern, power-efficient systems. The 6 nm process node from TSMC represents a more advanced manufacturing technology, which historically translates to better performance per watt.
