AMD EPYC 7401P vs Intel Core i7-12700T Comparison

The AMD EPYC 7401P and Intel Core i7-12700T occupy opposite ends of the computing spectrum, yet both land at the 61st percentile among all CPUs. The data presents a fascinating split: the EPYC dominates every Cinebench test, while the Core i7 sweeps both Geekbench tests. This is not a case of one being universally faster; it is a case of two very different architectures producing results that favor distinct workloads.

Where Each One Wins

The EPYC 7401P is the clear winner in all six Cinebench benchmarks, covering both R15, R20, and R23, and in both single-core and multi-core variants. The margin is consistent, hovering around 31.3% to 31.4% across every Cinebench test. The largest absolute lead is in Cinebench R23 multi-core, where the EPYC scores 23660 against the Core i7's 18012. This consistency suggests a fundamental advantage in sustained rendering workloads, likely stemming from its 24 cores and 48 threads—double the core count and more than double the thread count of the Intel part.

The Core i7-12700T wins decisively in Geekbench, both multi-core and single-core. In Geekbench multi-core, it scores 11502 versus the EPYC's 4666, a 59.4% advantage. In Geekbench single-core, the gap grows to 62.3%, with the Core i7 scoring 2089 against the EPYC's 787. This indicates that the Core i7's architecture is far more efficient in tasks that rely on high clock speeds and modern instruction-level parallelism, such as general desktop productivity, web browsing, and lightly-threaded applications.

The split is stark: Cinebench rewards the EPYC's raw thread count, while Geekbench rewards the Core i7's higher boost clock of 4.70 GHz and newer microarchitecture. The EPYC's boost clock is 3.00 GHz, which is 36% lower, but it compensates with sheer core count.

The Verdict

Choose the AMD EPYC 7401P if your workloads are heavily threaded and render-centric. The data shows it is 31.4% faster in Cinebench R23 multi-core, a benchmark that scales well with cores. This makes it the logical choice for server-side rendering, video encoding, and scientific computing tasks that can utilize 48 threads. Its eight-channel DDR4 memory support with 170.6 GB/s of bandwidth also favors memory-intensive server workloads.

Choose the Intel Core i7-12700T if your priority is responsiveness in everyday desktop tasks and applications that are not fully multi-threaded. The 62.3% lead in Geekbench single-core is enormous, and the 59.4% lead in Geekbench multi-core shows it handles mixed workloads far better. Its 35W TDP, integrated UHD Graphics 770, and dual-channel DDR4/DDR5 support make it a practical and efficient desktop processor.

If you are building a dedicated rendering node, the EPYC is the winner. If you are building a general-purpose PC, the Core i7 is the better fit. The data does not support a single "best" CPU; it supports two different best CPUs for two different jobs.

Head-to-Head Benchmarks

The most striking pattern is the uniform Cinebench deltas. In Cinebench R15 multi-core, the EPYC scores 2384 against 1815, a 31.3% win. In Cinebench R15 single-core, the EPYC scores 336 against 256, also a 31.3% win. This exact same percentage appears in R20 and R23, with the EPYC winning by 31.4% in all four of those tests. The consistency across different Cinebench versions suggests the EPYC's advantage is structural, not workload-specific.

The Geekbench results invert the picture completely. In Geekbench multi-core, the Core i7's 11502 crushes the EPYC's 4666, a 59.4% margin. In Geekbench single-core, the Core i7's 2089 versus 787 represents a 62.3% gap. These are not small margins; they are generational leaps. The EPYC, released in 2017, uses the Zen architecture, while the Core i7 uses Alder Lake, a much newer design. The Geekbench suite clearly rewards the newer architecture's IPC improvements and higher clocks.

The average benchmark scores reinforce the duality. The EPYC has an average benchmark score of 5814, while the Core i7 sits at 5606. The EPYC's nearest rival is the Intel Xeon E-2388G, which is only 0.2% behind. The Core i7's nearest rival is the AMD Ryzen 7 PRO 3700, which is 0.1% behind. Both are closely matched in overall average, but the constituent benchmarks tell very different stories.

Architecture Differences

The AMD EPYC 7401P is built on the Zen architecture, codenamed Naples, using a 14 nm process at GlobalFoundries. It is a server/workstation part for AMD Socket SP3, with 4,800 million transistors on a 213 mm² die. Its L1 cache is 96 KB per core, L2 is 512 KB per core, and it shares 64 MB of L3 cache across all cores.

The Intel Core i7-12700T uses the Alder Lake architecture, specifically Alder Lake-S, on a 10 nm process at Intel. It is a desktop part for Intel Socket 1700, with a 215 mm² die size. Its L1 cache is 80 KB per core, L2 is 1.25 MB per core, and it shares 25 MB of L3 cache.

The memory controllers are fundamentally different. The EPYC supports DDR4 over an eight-channel bus, delivering 170.6 GB/s of bandwidth. The Core i7 supports both DDR4 and DDR5 over a dual-channel bus, but the FACT PACK does not list a bandwidth figure for it. The EPYC also supports ECC memory, which the Core i7 lacks.

The EPYC's PCIe support is Gen 3, while the Core i7 offers Gen 5 with 20 lanes (CPU only). The EPYC is a server chip with no integrated graphics, while the Core i7 includes UHD Graphics 770. The EPYC has an unlocked multiplier, while the Core i7's multiplier is locked.

The release dates differ significantly: the EPYC was released in 2017, while the Core i7's release date is not listed. The manufacturing process node is 14 nm for the EPYC versus 10 nm for the Core i7, which partly explains the Core i7's higher boost clock of 4.70 GHz versus the EPYC's 3.00 GHz.
