Architecture Differences

The AMD Ryzen 7 5700 is built on Zen 3 architecture with the Cezanne codename, fabricated by TSMC on a 7 nm process. The Intel Core i7-11700KF uses Rocket Lake architecture, manufactured by Intel on a 14 nm process. This process difference is substantial: AMD’s smaller node allows for a die size of 180 mm² with 10,700 million transistors, while Intel’s larger process yields a die size of 276 mm² with no transistor count listed in the data.

The cache hierarchies differ. The AMD processor has 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of L3 cache. The Intel processor has 80 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The L3 total is identical at 16 MB, but Intel’s L1 is larger per core.

Memory support is similar: both support DDR4 with dual-channel memory buses and identical 51.2 GB/s memory bandwidth. However, AMD supports ECC memory while Intel does not. PCIe connectivity differs: the AMD Ryzen 7 5700 offers Gen 3 with 20 lanes (CPU only), while the Intel Core i7-11700KF offers Gen 4 with 20 lanes (CPU only). This gives Intel a newer PCIe generation.

Neither processor includes integrated graphics. The AMD part is designated as an 8-core, 16-thread desktop chip from the 5000 series, while the Intel part is from the Core 11th Gen series (Rocket Lake-S). The AMD processor’s production status is “Active,” whereas the Intel processor is marked “End-of-life.” Release dates differ: the AMD Ryzen 7 5700 launched on 2022-04-03, while the Intel Core i7-11700KF launched on 2021-03-15.

Power characteristics differ significantly. The AMD Ryzen 7 5700 has a TDP of 65 watts, while the Intel Core i7-11700KF has a TDP of 125 watts — nearly double. This is a critical architectural difference, as the AMD part achieves comparable or better performance in many tests while drawing far less power.

Where Each One Wins

The Intel Core i7-11700KF dominates in 3DMark benchmarks. It wins all six 3DMark tests, including single-thread (978 vs 901, +7.9%), 2-thread (1909 vs 1762, +7.7%), 4-thread (3645 vs 3382, +7.2%), 8-thread (6294 vs 5585, +11.3%), 16-thread (8067 vs 6628, +17.8%), and max-thread (8049 vs 6617, +17.8%). This pattern suggests the Intel chip is better suited for gaming workloads that rely on moderate thread counts and high frequency.

The AMD Ryzen 7 5700 wins every Cinebench test, from R15 single-core (293 vs 287, +2.1%) through R23 multi-core (20655 vs 20214, +2.2%). It also wins several PassMark workloads: data encryption (20096 vs 15229, +32%), floating point math (51427 vs 50571, +1.7%), integer math (90091 vs 85377, +5.5%), and multithread (24303 vs 23819, +2%). The 32% encryption lead is the largest single margin in the entire comparison.

The Intel chip wins the remaining PassMark tests: data compression (317712 vs 316699, +0.3%), extended instructions (22247 vs 21945, +1.4%), find prime numbers (62 vs 58, +6.5%), physics (985 vs 984, +0.1%), random string sorting (36309 vs 33138, +8.7%), and single-thread (3368 vs 3296, +2.1%). Intel also wins Geekbench multi-core (10565 vs 9959, +5.7%) and single-core (1938 vs 1907, +1.6%).

For gaming and light-threaded applications, the Intel Core i7-11700KF is the stronger pick. For encryption, integer-heavy workloads, and sustained multi-core rendering tasks, the AMD Ryzen 7 5700 takes the lead. The overall win count favors Intel: 15 benchmark wins for Intel versus 10 for AMD.

The two processors share identical core counts (8), thread counts (16), L2 cache per core (512 KB), memory support (DDR4), memory bus (dual-channel), and memory bandwidth (51.2 GB/s). Both have unlocked multipliers, no integrated graphics, and target the desktop market segment. The part numbers differ: 100-000000743 for AMD and SRKNN for Intel.

The most consequential differences are TDP (65W vs 125W), boost clock (4.60 GHz vs 5.00 GHz), and PCIe generation (Gen 3 vs Gen 4). The AMD chip is also much newer (2022 vs 2021) and remains in active production, while the Intel chip is end-of-life.

Head-to-Head Benchmarks

The head-to-head results reveal a clear split: Intel wins the 3DMark suite convincingly, while AMD wins the Cinebench suite by a consistent margin. The largest Intel victory comes in 3DMark 16-thread and max-thread, where the Core i7-11700KF scores 8067 and 8049 respectively, against the Ryzen 7 5700’s 6628 and 6617. That is a 17.8% deficit for AMD in both cases. The Intel chip also wins 3DMark 8-thread by 11.3% (6294 vs 5585) and single-thread by 7.9% (978 vs 901).

The AMD Ryzen 7 5700’s biggest win is PassMark data encryption, where it scores 20096 against Intel’s 15229 — a 32% advantage. This is the only test with a double-digit margin in AMD’s favor. AMD also wins PassMark integer math by 5.5% (90091 vs 85377) and PassMark multithread by 2% (24303 vs 23819).

In Cinebench, the AMD chip wins all six tests by exactly 2.2%: R15 multi-core (2082 vs 2037), R15 single-core (293 vs 287), R20 multi-core (8675 vs 8489), R20 single-core (1224 vs 1198), R23 multi-core (20655 vs 20214), and R23 single-core (2916 vs 2853). This uniformity suggests a consistent architectural efficiency advantage for Zen 3 in rendering workloads.

Geekbench favors Intel: multi-core 10565 vs 9959 (+5.7%) and single-core 1938 vs 1907 (+1.6%). PassMark tests split more evenly, with Intel winning random string sorting by 8.7% (36309 vs 33138), find prime numbers by 6.5% (62 vs 58), and single-thread by 2.1% (3368 vs 3296). AMD wins floating point math by 1.7% (51427 vs 50571) and data encryption by 32%.

The closest contest is PassMark physics: Intel wins 985 to 984, a 0.1% margin. PassMark data compression is nearly as tight: Intel wins 317712 to 316699, a 0.3% margin. These near-ties highlight how evenly matched the two processors are in certain integer-heavy workloads.

The Verdict

The data presents two distinct profiles. The Intel Core i7-11700KF wins 15 of 25 head-to-head benchmarks, with its strongest showing in 3DMark tests where it leads by up to 17.8%. The AMD Ryzen 7 5700 wins 10 benchmarks, with its decisive victory in PassMark data encryption (32% ahead) and a clean sweep of all Cinebench tests.

For gaming and applications that stress moderate thread counts with high clock speeds, the Intel Core i7-11700KF is the better choice based on its 3DMark dominance and higher boost clock of 5.00 GHz. The Intel chip also leads in Geekbench single-core and multi-core, making it a solid all-rounder for mixed workloads.

For rendering, encryption, and integer-heavy computing, the AMD Ryzen 7 5700 is the stronger option. Its 2.2% lead across every Cinebench test demonstrates consistent multi-core efficiency, and the 32% encryption advantage is substantial. The AMD chip achieves this while drawing a TDP of 65 watts versus Intel’s 125 watts.

The AMD processor also has practical advantages: it is in active production, supports ECC memory, and was released later (2022 vs 2021). The Intel processor is end-of-life. The launch MSRP differs: $179 for AMD versus $374 for Intel, though this data should not be interpreted as a value judgment.

The average benchmark scores are nearly identical — 25517 for AMD versus 25423 for Intel — and both sit at the 77th-78th percentile of all CPUs. The nearest rivals for each processor include AMD Ryzen 7 5825U (25446 average score) and AMD Ryzen 5 5600X3D (25365), confirming these two chips compete in the same performance tier.

Choose the Intel Core i7-11700KF if gaming performance and 3DMark-style workloads are the priority. Choose the AMD Ryzen 7 5700 if rendering consistency, encryption throughput, and lower power draw matter more. The overall win count favors Intel, but the margin is narrow in most tests, and the AMD chip’s advantages in Cinebench and encryption are meaningful for specific use cases.
