Both are unlocked multipliers. Sockets differ: AM5 for AMD, LGA1700 for Intel.

Head-to-Head Benchmarks

Across all 19 head-to-head tests, the AMD Ryzen 9 9950X wins every one. The largest margin is in Passmark extended instructions, where AMD scores 71564 versus Intel's 40632, a 76.1% advantage. Passmark find prime numbers shows AMD at 345 versus 212, a 62.7% lead. In Passmark integer math, AMD leads 242097 to 182876, a 32.4% delta. Data compression: AMD 896544 vs 695234, 29% ahead. Random string sorting: 94368 vs 74733, 26.3%. Cinebench R15, R20, and R23 multicore and single-core all show AMD ahead by 26% (with R15 single-core at 26.1%). Passmark multithread: 66030 vs 52392, 26% delta. Floating point math: 159063 vs 134222, 18.5%. Geekbench multicore: 21441 vs 18896, 13.5%; single-core 3386 vs 2932, 15.5%. Data encryption: 44366 vs 40091, 10.7%. Physics: 3279 vs 2964, 10.6%. Passmark single-thread: 4737 vs 4472, 5.9%. The only sub-10% win is single-thread Passmark at 5.9%. The consistent pattern is AMD dominance across synthetic rendering, math, encryption, and compression workloads.

Specification Differences

The two CPUs differ in nearly every physical and feature specification. Core count: AMD 16, Intel 20. Threads: AMD 32, Intel 28. Base clock: AMD 4.30 GHz, Intel 3.40 GHz. Boost clock: AMD 5.70 GHz, Intel 5.60 GHz. TDP: AMD 170 W, Intel 125 W. Socket: AMD Socket AM5, Intel Socket 1700. Process node: AMD 4 nm, Intel 10 nm. Foundry: TSMC vs Intel. Die size: AMD 2x 70.6 mm², Intel 257 mm². Transistors: AMD 16,630 million, Intel not disclosed. L2 cache: AMD 1 MB per core, Intel 2 MB per core. L3 cache: AMD 64 MB shared, Intel 33 MB shared. Memory support: AMD DDR5 only, Intel DDR4 and DDR5. Memory bandwidth: AMD 89.6 GB/s, Intel not listed. PCIe lanes: AMD 24, Intel 16. Integrated graphics: AMD Radeon Graphics, Intel UHD Graphics 770. Launch MSRP: AMD $649, Intel $409 (each stated once). Both have ECC support, unlocked multiplier, dual-channel memory bus, and are active desktop parts.

The Verdict

The data is unambiguous: the AMD Ryzen 9 9950X outperforms the Intel Core i7-14700K in every single benchmark recorded, with margins ranging from 5.9% to 76.1%. Both processors sit in the 96th percentile of all CPUs, but AMD's average benchmark score of 70420 edges Intel's 70074 by 0.5%. For users prioritizing raw performance in rendering, math, compression, and encryption, the AMD part is the clear choice. The Intel part does offer a lower TDP (125 W vs 170 W) and support for DDR4 memory, which could be relevant for certain platform constraints, but those are not performance advantages. The Intel part also has a higher core count (20 vs 16) yet fewer threads (28 vs 32), and it still loses all multithreaded tests. Based solely on benchmark results, the AMD Ryzen 9 9950X is the superior processor.

Where Each One Wins

Since the AMD Ryzen 9 9950X wins all 19 head-to-head benchmarks, there is no workload category where the Intel Core i7-14700K takes the lead. The AMD part wins in Cinebench R15/R20/R23 multicore and single-core, Geekbench multicore and single-core, and every Passmark subtest including data compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithread, physics, random string sorting, and single-thread. The only close contest is Passmark single-thread, where AMD leads by 5.9%. For any use case that relies on the tested workloads—video rendering, scientific computing, encryption, compression, general productivity—the AMD Ryzen 9 9950X is the winner. The Intel Core i7-14700K, while competitive in single-threaded Passmark, does not achieve a single victory in the provided data. Therefore, the "where each one wins" split is entirely one-sided: AMD wins everywhere.
