AMD Ryzen 9 7900 vs Intel Core i5-14600KF Comparison

The Intel Core i5-14600KF and AMD Ryzen 9 7900 are two of the most competitive desktop processors in their respective lineups, both holding the 90th percentile in benchmarks against all CPUs. The data shows a distinct split in their performance profiles, with the Intel part dominating in single-threaded and specific rendering workloads, while the AMD Ryzen 9 7900 takes a decisive lead across the majority of multi-threaded and specialized compute tests. Their average benchmark scores are nearly identical, with the Intel chip at 49394 and the AMD chip at 49228, a margin of just 0.3% favoring Intel. This near-parity in overall averages, however, masks substantial differences in how each processor handles individual tasks, making the choice between them heavily dependent on the intended workload.

Head-to-Head Benchmarks

The most dramatic single result in the head-to-head comparison comes from the Cinebench suite. In Cinebench R23 single-core, the Intel Core i5-14600KF scores 4594, which is 133.7% higher than the AMD Ryzen 9 7900’s 1966. This is an enormous lead that underscores a fundamental architectural advantage for Intel in lightly-threaded tasks. The same pattern appears in Cinebench R15 single-core, where Intel wins with a score of 462 versus AMD’s 315, a 46.7% difference. These results are not minor margins; they represent a generational gap in single-thread performance.

However, the multi-core results tell a completely different story. In Cinebench R23 multi-core, the Intel Core i5-14600KF reverses the trend, scoring 32544 against the AMD Ryzen 9 7900’s 24776, a 31.4% win for Intel. Yet, in the older Cinebench R15 multi-core test, the AMD Ryzen 9 7900 wins decisively with 4020 points versus Intel’s 3280, an 18.4% advantage for AMD. This inconsistency between different versions of the same benchmark suggests that the Ryzen 9 7900 scales better in certain multi-threaded conditions, while the Intel chip excels in others.

Outside of Cinebench, the AMD Ryzen 9 7900 dominates the Passmark suite. In Passmark integer math, AMD scores 164075 against Intel’s 125982, a 23.2% lead. The gap widens further in Passmark extended instructions, where AMD’s 42253 is 31.9% higher than Intel’s 28785. The AMD processor also wins in Passmark data encryption (34708 vs 27608, a 20.5% margin), Passmark data compression (577847 vs 485140, a 16% margin), and Passmark find prime numbers (380 vs 161, a 57.6% margin). Even in Passmark floating point math, AMD leads with 97943 versus Intel’s 93048, a 5% difference.

The Geekbench results are closer, but still favor AMD. In Geekbench multi-core, the Ryzen 9 7900 scores 17726 versus Intel’s 17085, a 3.6% lead. In Geekbench single-core, AMD again wins with 2495 against Intel’s 2445, a 2% margin. The only other win for Intel outside of Cinebench is in Passmark single-thread, where Intel scores 4273 versus AMD’s 4130, a 3.5% advantage. The overall win count reflects this distribution: the AMD Ryzen 9 7900 wins 12 of the 17 head-to-head benchmarks, while the Intel Core i5-14600KF wins 5.

Where Each One Wins

The Intel Core i5-14600KF’s wins are concentrated in areas that require high clock speeds and strong per-core efficiency. Its Cinebench R23 single-core score of 4594 is the standout, suggesting it is the better choice for applications that are not well-optimized for many cores, such as older games or legacy software. The 133.7% lead in this test is not just a victory; it is a categorical one. Similarly, its Cinebench R23 multi-core win of 32544 indicates that in certain modern rendering workloads, the Intel chip can leverage its 14 cores (with 20 threads) to outperform a processor with fewer physical cores. The Passmark single-thread score of 4273, while a smaller 3.5% win, reinforces the Intel advantage in single-threaded responsiveness.

The AMD Ryzen 9 7900’s wins are broader and more numerous. Its 12-core, 24-thread configuration provides a clear advantage in heavily parallelized workloads. The Passmark results are particularly telling: the 31.9% lead in extended instructions and the 23.2% lead in integer math show that the Ryzen 9 7900 is superior for scientific computing, financial modeling, and any task that relies on AVX-512 or similar instruction sets. The 57.6% lead in find prime numbers is a classic indicator of raw computational throughput. In data compression and encryption, AMD’s 16% and 20.5% leads, respectively, make it the better choice for server-like tasks such as database management, file archiving, and secure communications. The Geekbench multi-core win of 3.6% and the Cinebench R15 multi-core win of 18.4% further cement the Ryzen 9 7900 as the multi-threaded workhorse.

The Verdict

Based strictly on the benchmark data, the choice between these two processors comes down to workload priority. For users who prioritize single-threaded performance, particularly in everyday applications, legacy software, or games that rely on high clock speeds, the Intel Core i5-14600KF is the clear winner. Its 133.7% lead in Cinebench R23 single-core is an overwhelming margin that cannot be ignored. The Intel chip also holds a significant advantage in Cinebench R23 multi-core, suggesting it is a strong option for certain modern rendering tasks that benefit from its specific core architecture.

Conversely, the AMD Ryzen 9 7900 is the superior choice for users who run a diverse range of multi-threaded and specialized compute tasks. With 12 wins out of 17 head-to-head benchmarks, it offers a more consistent performance profile across the board. The 31.9% lead in extended instructions and the 23.2% lead in integer math make it the go-to for developers, data analysts, and engineers. Its wins in data compression and encryption also make it a better fit for content creation workflows that involve large file transfers or secure data handling. The overall average benchmark score is nearly identical, but the Ryzen 9 7900 achieves this parity through breadth, while the Intel chip achieves it through depth in specific areas.

Architecture Differences

The architectural split between the two processors is stark. The Intel Core i5-14600KF uses the Raptor Lake architecture (codenamed Raptor Lake-R) built on Intel’s 10 nm process node. It has 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a shared 24 MB L3 cache. The die size is 257 mm². It supports both DDR4 and DDR5 memory on a dual-channel bus, and it includes ECC memory support. The processor uses Intel Socket 1700 and features PCIe Gen 5 with 16 lanes (CPU only). It has a TDP of 125 and an unlocked multiplier. Its launch MSRP was $294.

The AMD Ryzen 9 7900, in contrast, uses the Zen 4 architecture (codenamed Raphael) built on TSMC’s 5 nm process node. It has 12 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 5.40 GHz. Its cache layout is different, with 64 KB of L1 per core, 1 MB of L2 per core, and a much larger shared 64 MB L3 cache. The die size is 2x 71 mm², and the processor contains 13,140 million transistors. It supports DDR5 memory only, on a dual-channel bus, with a memory bandwidth of 83.2 GB/s. It also supports ECC memory. The processor uses AMD Socket AM5 and features PCIe Gen 5 with 24 lanes (CPU only). It includes integrated Radeon Graphics, unlike the Intel chip which has no integrated graphics. It has a TDP of 65 and an unlocked multiplier. Its launch MSRP was $429.

The differences in cache size and process node are significant. AMD’s 64 MB L3 cache is over twice the size of Intel’s 24 MB, which likely contributes to its wins in data-heavy workloads. The smaller 5 nm process node, manufactured by TSMC, allows for higher efficiency, reflected in the lower TDP of 65 versus Intel’s 125. The Intel chip’s higher TDP and larger die size suggest it is designed for maximum clock speeds, while the AMD chip’s smaller, more numerous cores are optimized for parallel throughput. The inclusion of integrated graphics on the AMD chip is a notable feature absent from the Intel part, and the 24 PCIe lanes on AMD versus 16 on Intel offer more expansion potential.
