AMD Ryzen 5 7600 vs Intel Core i9-11900KF Comparison

The AMD Ryzen 5 7600 and Intel Core i9-11900KF present a fascinating generational clash, ending in a near statistical dead heat. The data shows the Ryzen 5 7600 wins 11 benchmark comparisons, while the Intel Core i9-11900KF takes 12, and their overall average benchmark scores are separated by less than half a percent (26324 vs 26212). This is not a rout in either direction; it is a split decision defined by workload type, with each processor staking a clear claim to a different category of performance.

Head-to-Head Benchmarks

The most dramatic individual victory belongs to AMD in the passmark_find_prime_numbers test. The Ryzen 5 7600 scores 200 against the Intel's 66, a staggering 203% deltaPct advantage. This is a pure arithmetic and cache-latency exercise where Zen 4's architecture is decisively superior. Similarly, in passmark_physics, the AMD part posts a 71.8% lead (1776 vs 1034), indicating a significant advantage in simulation and physics calculations that favor its newer core design.

The AMD Ryzen 5 7600 also dominates in Geekbench results. It leads the Intel part by 22.5% in geekbench_multicore (13413 vs 10953) and by 22.3% in geekbench_singlecore (2521 vs 2062). These results suggest that in broader, more diverse system-level workloads, the Zen 4 architecture is markedly more efficient. The AMD chip also wins cinebench_cinebench_r15_multicore by 11.4% (2339 vs 2100) and passmark_multithread by 9.5% (27058 vs 24708), while taking passmark_single_thread by 10.9% (3910 vs 3527). Its lead in passmark_data_encryption is 13.3% (17704 vs 15623), and it edges out a win in passmark_extended_instructions by 1.6% (23071 vs 22703).

The Intel Core i9-11900KF, however, flexes its muscle in multi-threaded rendering and raw throughput. Its biggest win is in cinebench_cinebench_r23_multicore, where it crushes the AMD chip by 38.9% (20838 vs 12735). It also wins cinebench_cinebench_r23_singlecore by 37% (2941 vs 1852), a surprising inversion of the Geekbench single-core result that highlights how different benchmark suites stress different parts of the microarchitecture. The Intel part also dominates in 3DMark tests, winning 3dmark_16_threads by 22% (8335 vs 6499) and 3dmark_max_threads by 21.9% (8322 vs 6503).

The Intel chip takes the remaining math and data tests. It leads passmark_integer_math by 9.5% (89023 vs 80581) and passmark_floating_point_math by 8.6% (52640 vs 48107). It also wins passmark_data_compression by 6.4% (325688 vs 304942) and passmark_random_string_sorting by 4% (37383 vs 35904). In lower-thread 3DMark runs, the Intel part holds a slim but consistent advantage, winning 3dmark_2_threads by 3.3%, 3dmark_4_threads by 3.9%, and 3dmark_8_threads by 17.4%. The only sub-10-point win for AMD is in cinebench_cinebench_r15_singlecore, where it leads by a marginal 0.7% (298 vs 296).

The Verdict

The data paints a clear picture for different user profiles. The AMD Ryzen 5 7600 is the better choice for users who prioritize system-level responsiveness, general productivity, and encryption or physics workloads. Its substantial wins in Geekbench, passmark_multithread, and passmark_physics indicate a more balanced and modern processor that excels in a variety of everyday and professional tasks. The 203% lead in prime number finding and 71.8% lead in physics suggest it is the superior engine for scientific computing and complex simulations.

The Intel Core i9-11900KF is the pick for content creators and professionals who rely on multi-threaded rendering. The 38.9% lead in Cinebench R23 multi-core is a massive margin that will translate to directly faster render times in applications like Cinema 4D. Its consistent wins across 3DMark and integer math also make it a compelling option for those whose workloads are heavily threaded and math-intensive. However, its 22% deficit in Geekbench multi-core and 10.9% loss in PassMark single-thread indicate that its architecture is less efficient in lighter, more latency-sensitive tasks.

Given the near-identical average benchmark scores, the decision comes down to workload specificity. If the primary application is a 3D rendering or video encoding suite that scales with core count and raw throughput, the Intel i9-11900KF is justified by the data. If the workload is more varied—spanning office productivity, code compilation, and simulation—the AMD Ryzen 5 7600 offers the more versatile performance profile. The Intel chip's 125W TDP is also a relevant consideration against the AMD's 65W TDP for system builders, though the performance-per-watt ratio is not directly benchmarked here.

Architecture Differences

The two processors are built on vastly different foundations. The AMD Ryzen 5 7600 uses the Zen 4 architecture on a 5 nm process node fabricated by TSMC, while the Intel Core i9-11900KF uses the Rocket Lake architecture on Intel's 14 nm process. This process gap explains the significant difference in die size and transistor count: the AMD chip has a die size of 71 mm² and 6,570 million transistors, whereas the Intel part has a much larger 276 mm² die and a null transistor count in the data.

Core configuration differs as well. The AMD part has 6 cores and 12 threads, while the Intel part has 8 cores and 16 threads. The Intel chip compensates for its older process with more physical cores. Cache layouts are also distinct. AMD uses a larger L3 cache of 32 MB shared, with 1 MB of L2 per core and 64 KB of L1 per core. Intel uses a smaller 16 MB shared L3, 512 KB of L2 per core, and a larger 80 KB of L1 per core.

Memory support marks a generational divide. The AMD Ryzen 5 7600 supports DDR5 memory with a dual-channel bus and a theoretical bandwidth of 83.2 GB/s, and it supports ECC memory. The Intel Core i9-11900KF supports DDR4 memory with a dual-channel bus and a lower theoretical bandwidth of 51.2 GB/s, and it does not support ECC. The AMD chip also offers PCIe Gen 5 with 24 lanes, while the Intel part is limited to PCIe Gen 4 with 20 lanes. The AMD part includes integrated Radeon Graphics, whereas the Intel 'KF' suffix indicates no integrated graphics.
