CPU Comparison

Head-to-Head Benchmarks

The recorded Cinebench results paint a stark picture of performance asymmetry. Across all six head-to-head tests, the AMD EPYC 9654 claims victory with a consistent and dominant margin. The most dramatic gap appears in Cinebench R15 multicore, where the EPYC 9654 scores 10,248 against the Intel Core i5-12600's 1,824, a delta of 461.8%. That same percentage, 461.6%, repeats across Cinebench R20 multicore (42,703 vs 7,604) and Cinebench R23 multicore (101,675 vs 18,105). The consistency of these deltas, hovering in the 461% to 462% range, indicates that the performance relationship between these two processors is stable regardless of the rendering workload intensity.

Single-core results tell a similar story, though the absolute numbers are smaller. The EPYC 9654 posts 1,446 in Cinebench R15 single-core versus 257 for the i5-12600, a 462.6% advantage. In Cinebench R20 single-core, the scores are 6,028 and 1,073 respectively, again a 461.8% delta. Cinebench R23 single-core shows 14,354 for the EPYC against 2,556 for the Intel part, a 461.6% margin. These single-core deltas are nearly identical to the multicore ones, which is notable: the EPYC 9654 does not merely scale better with more cores, it also leads in per-thread performance within this specific benchmark suite.

The wins tally sits at 6 for the AMD EPYC 9654 and 0 for the Intel Core i5-12600. The Intel processor's own benchmark record does include additional PassMark tests, but those have no corresponding EPYC entries in the database, so no direct head-to-head comparison can be drawn from them. Within the available Cinebench data, the EPYC 9654 outperforms the Core i5-12600 by a factor of roughly 5.6x in every measured metric. The average benchmark scores reflect this overall standing: the EPYC 9654 sits at 29,409 with an 81st percentile across all CPUs, while the i5-12600 averages 28,646 at the 80th percentile. Interestingly, despite the massive gap in the direct comparisons, their aggregate scores are close, because the Intel part's PassMark results (for example, 252,160 in data compression and 66,123 in integer math) are not matched by EPYC entries in the database.

Architecture Differences

The two processors belong to completely different tiers of design. The AMD EPYC 9654 is a 96-core, 192-thread server processor built on TSMC's 5 nm process, featuring the Zen 4 architecture under the Genoa codename. It draws from the EPYC 9004 series and uses AMD Socket SP5. Its transistor count is listed at 78,840 million, spread across a multi-chiplet design with a die size of 12x 72 mm². The cache hierarchy is generous: 64 KB of L1 per core, 1 MB of L2 per core, and 384 MB of shared L3. Memory support covers DDR5 with a twelve-channel bus and 460.8 GB/s of bandwidth. ECC memory is supported, and PCIe connectivity reaches Gen 5 with 128 lanes (CPU only). This is a part engineered for massive parallel workloads, with no integrated graphics and a market segment classified as Server/Workstation.

The Intel Core i5-12600, by contrast, is a 6-core, 12-thread desktop processor from the Core 12th Gen series, built on Intel's 10 nm process using the Alder Lake architecture (Alder Lake-S). It fits Intel Socket 1700 and has a 163 mm² die size. Cache amounts are far smaller: 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. Memory support includes both DDR4 and DDR5, but only through a dual-channel bus, and no memory bandwidth figure is recorded. ECC is not supported. PCIe is Gen 5 but limited to 16 lanes (CPU only). The i5-12600 does include integrated graphics in the form of UHD Graphics 770, and its market segment is Desktop.

The architectural gap explains the benchmark results. The EPYC 9654 has 16 times the cores of the i5-12600, and its L3 cache is over 21 times larger. The process node advantage (5 nm versus 10 nm) contributes to the EPYC's ability to sustain higher performance per watt in heavily threaded workloads, even though its TDP of 360 watts dwarfs the Intel part's 65 watts. The memory subsystem also diverges sharply: twelve-channel DDR5 with ECC versus dual-channel DDR4/DDR5 without ECC. These are not competing designs in any conventional sense; they target different sockets, different power envelopes, and different workload classes.

The Verdict

The data favors one processor overwhelmingly in raw performance. The AMD EPYC 9654 outperforms the Intel Core i5-12600 by margins between 461.6% and 462.6% across every Cinebench test recorded. The EPYC's 96 cores, 192 threads, and 384 MB of L3 cache are directly reflected in these scores, and its 81st percentile standing among all CPUs confirms its high-end placement. The Intel Core i5-12600, with 6 cores and 12 threads, is not in the same performance class; its 80th percentile is respectable for a desktop chip, but the head-to-head data shows no scenario where it closes the gap.

The choice between these two depends entirely on workload context. For server or workstation deployments requiring massive parallelism, memory bandwidth, and ECC reliability, the EPYC 9654 is the only sensible option from this comparison. Its twelve-channel DDR5 support and 460.8 GB/s bandwidth are designed for exactly that role. For a desktop system where integrated graphics, lower power consumption (65 watts versus 360 watts), and dual-channel memory suffice, the i5-12600 fulfills a standard desktop role. But within the benchmark metrics available, there is no recorded test where the Intel part wins. The verdict is unambiguous: the EPYC 9654 is the dominant processor in every measured performance category.

Where Each One Wins

The AMD EPYC 9654 wins every benchmark category that has a direct comparison. In Cinebench R15, R20, and R23, both single-core and multicore, the EPYC leads by roughly 461% to 462%. This makes it the clear choice for any workload that relies on sustained rendering, simulation, or compilation across many threads. Its 192 threads and 384 MB of L3 cache are the structural reasons for this dominance. The EPYC also wins in memory-related capabilities: twelve-channel DDR5 with ECC and 460.8 GB/s bandwidth are features the Intel part cannot match. For server virtualization, large-scale database work, or scientific computing, the EPYC 9654 is the processor the data supports.

The Intel Core i5-12600 has no recorded benchmark wins against the EPYC 9654. Its strengths lie outside the head-to-head comparisons. It has a higher base clock (3.30 GHz versus 2.40 GHz) and boost clock (4.80 GHz versus 3.70 GHz), which may benefit lightly threaded tasks, though the single-core Cinebench results do not reflect any advantage. It includes integrated graphics, which the EPYC lacks entirely. Its 65 watt TDP is substantially lower than the EPYC's 360 watts, making it suitable for power-constrained desktop builds. The i5-12600 also supports both DDR4 and DDR5 memory, offering flexibility in platform choice, and its 80th percentile average score shows it performs adequately relative to the broader CPU landscape. The PassMark results for the i5-12600, such as 252,160 in data compression and 66,123 in integer math, indicate competence in desktop productivity tasks, but no EPYC PassMark data exists for direct comparison.

In practical terms, the EPYC 9654 wins where thread count and memory bandwidth matter most. The i5-12600 wins where power efficiency, integrated graphics, and desktop form factor matter most. The benchmark database records no performance test where the Intel part overtakes the AMD part, so any selection of the i5-12600 must rest on non-performance criteria from the recorded data.
