AMD Ryzen 7 5800X vs Intel Core i5-12600 Comparison

The comparison between the AMD Ryzen 7 5800X and the Intel Core i5-12600 reveals a clear split: the AMD chip dominates in most multi-threaded and specialized workloads, while the Intel chip counters with superior single-thread performance and a notable win in one of the most demanding rendering tests. The database records 10 benchmark wins for the AMD Ryzen 7 5800X against 5 for the Intel Core i5-12600, but the magnitude of the Intel victories in key areas tells a more nuanced story.

Head-to-Head Benchmarks

The most significant single result in this matchup is in Cinebench R23 multi-core, where the Intel Core i5-12600 posts a score of 18105 against the AMD Ryzen 7 5800X's 15476. This translates to a 14.5% advantage for Intel in a heavily threaded rendering workload, which is surprising given that the AMD chip has 8 cores and 16 threads compared to Intel's 6 cores and 12 threads. The Intel lead in Cinebench R23 single-core is even more pronounced: a score of 2556 versus 1574.5, a 38.4% gap. This is the largest percentage difference in any of the recorded tests.

The AMD Ryzen 7 5800X, however, establishes dominance in the older Cinebench R15 benchmark. It wins multi-core with a score of 2608.5 versus 1824, a 43% margin, and single-core with 265.5 versus 257, a narrower 3.3% edge. The discrepancy between the R15 and R23 results suggests the Intel chip's architecture scales better with the newer benchmark's instruction set and workload characteristics, while the AMD chip's raw core count drives its advantage in the older test.

In PassMark tests, the AMD Ryzen 7 5800X wins 7 out of 9 head-to-head comparisons. The largest win is in data encryption: 21191 versus 13084, a 62% advantage. Integer math shows a 43.6% lead (94969 versus 66123), and find prime numbers shows a 49.4% lead (124 versus 83). Data compression and random string sorting each show a 37% advantage for AMD (345414 versus 252160, and 35401 versus 25832, respectively). Extended instructions follow with a 38.4% lead (23573 versus 17027). The AMD chip also wins PassMark multi-thread with 27732 versus 21399, a 29.6% margin, and floating point math by a slim 3.5% (52639 versus 50838).

The Intel Core i5-12600 takes the PassMark single-thread tests with a score of 3823 versus 3445, a 9.9% lead. The closest contest in the entire dataset is PassMark physics, where Intel wins by a single point: 1365 versus 1364, a 0.1% difference that is statistically negligible.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 5800X uses the Zen 3 architecture, codenamed Vermeer, manufactured on a 7 nm process by TSMC. The Intel Core i5-12600 uses the Alder Lake architecture, specifically Alder Lake-S, manufactured on a 10 nm process by Intel's own foundry. This process node difference (7 nm versus 10 nm) is reflected in the die sizes: the AMD chip measures 74 mm² with 4,150 million transistors, while the Intel chip is substantially larger at 163 mm² (the transistor count for Intel is not recorded in the database).

Core configuration differs significantly. The AMD Ryzen 7 5800X offers 8 cores and 16 threads, while the Intel Core i5-12600 offers 6 cores and 12 threads. This gives AMD a 33% advantage in core count and thread count. The cache hierarchy also differs: AMD uses 64 KB of L1 cache and 512 KB of L2 cache per core, with 32 MB of shared L3 cache. Intel uses 80 KB of L1 cache and 1.25 MB of L2 cache per core, but only 18 MB of shared L3 cache. Intel's larger per-core L1 and L2 caches may contribute to its single-thread performance advantage, while AMD's larger L3 cache (32 MB versus 18 MB) helps in multi-threaded scenarios.

The base and boost clocks tell a similar story. The AMD chip has a higher base clock at 3.80 GHz versus Intel's 3.30 GHz, but Intel's boost clock is higher at 4.80 GHz versus AMD's 4.70 GHz. The Intel chip also runs at a lower TDP of 65 watts compared to AMD's 105 watts, indicating higher power efficiency in the recorded specifications.

Memory support diverges: the AMD chip supports only DDR4, while the Intel chip supports both DDR4 and DDR5. Both use dual-channel memory buses. AMD records a memory bandwidth of 51.2 GB/s, while Intel's bandwidth is not listed. ECC memory support is present on the AMD chip but absent on the Intel chip. PCIe connectivity also differs: AMD offers Gen 4 with 20 lanes, while Intel offers Gen 5 with 16 lanes. The Intel chip includes integrated graphics (UHD Graphics 770), while the AMD chip has none. The AMD chip has an unlocked multiplier, while the Intel chip is locked.

The Verdict

The data presents a clear choice based on workload priorities. For users running applications that rely heavily on single-thread performance, the Intel Core i5-12600 is the stronger option. Its 38.4% lead in Cinebench R23 single-core and 9.9% lead in PassMark single-thread are substantial, and its win in Cinebench R23 multi-core (14.5% ahead) demonstrates that it can handle modern rendering workloads effectively despite having fewer cores.

The AMD Ryzen 7 5800X, however, is the better choice for compute-heavy tasks that leverage many threads and specific instruction sets. It holds a 43% lead in Cinebench R15 multi-core, a 62% lead in data encryption, a 49.4% lead in prime number finding, and a 43.6% lead in integer math. Its overall multi-thread score from PassMark is 29.6% higher. The 10 wins versus 5 wins in the head-to-head benchmarks reflect this broad dominance across most tested categories.

The average benchmark scores in the database confirm the overall positioning: the AMD Ryzen 7 5800X has an average score of 29123, placing it in the 81st percentile of all CPUs, while the Intel Core i5-12600 has an average score of 28646, placing it in the 80th percentile. The delta between them is small in aggregate, but the distribution of wins is highly uneven. The AMD chip's nearest rivals include the Intel Core Ultra 5 135H with a delta of 0.1% and the AMD Ryzen 5 5600XT with a delta of 0.6%, while the Intel chip's nearest rivals include the Intel Core i5-13500T with a delta of -0.1% and the AMD Ryzen 7 PRO 6850HS with a delta of 0.3%.

In practical terms, the AMD Ryzen 7 5800X is suited for users running heavily threaded workloads, encryption tasks, or integer-heavy calculations, where its margins are decisive. The Intel Core i5-12600 is suited for users whose applications favor high single-thread performance or the newer Cinebench R23 rendering pipeline, and it also offers integrated graphics, a feature the AMD chip lacks entirely. The choice depends on whether the user's software stack aligns with AMD's strengths in broad multi-threading or Intel's strengths in single-thread speed and newer rendering benchmarks.
