Where Each One Wins

The Intel Core i5-12600H dominates in Cinebench across the board, winning all six Cinebench R15, R20, and R23 tests by a consistent 7.1-7.3% margin. This pattern extends to floating-point math, where Intel's 51,264 score crushes the EPYC's 37,049 by 38.4%, and to integer math (71,168 vs 67,083, a 6.1% lead). Single-thread performance is also firmly Intel's territory, with a 36.1% advantage in PassMark single-thread tests (3,453 vs 2,537). Extended instructions show a narrow 0.3% win for Intel (14,508 vs 14,466), making this the closest benchmark in the entire comparison.

The AMD EPYC 7203P wins in workloads that benefit from its massive 64 MB shared L3 cache and server-oriented design. Its most decisive victory is in prime number finding, where it scores 145 versus Intel's 71, a 51% advantage. Physics simulations also strongly favor AMD (2,077 vs 1,262, a 39.2% lead), as does random string sorting (33,873 vs 27,653, an 18.4% margin). Data encryption shows a 15.1% AMD win (17,434 vs 14,799), and data compression is a modest 2.7% AMD victory (254,215 vs 247,404). The EPYC also edges out Intel in multithread performance (22,017 vs 21,128, a 4% lead), despite having fewer physical cores.

Architecture Differences

The Intel Core i5-12600H uses the Alder Lake-H architecture, which employs a hybrid design combining high-performance and high-efficiency cores. This architecture is built on Intel's 10 nm process with a 217 mm² die, supporting both DDR4 and DDR5 memory through a dual-channel bus. The processor integrates Iris Xe graphics with 80 execution units, making it a complete system-on-chip for mobile devices. Its cache hierarchy uses 80 KB of L1 and 1.25 MB of L2 per core, with 18 MB of shared L3 cache.

The AMD EPYC 7203P is based on the Zen 3 Milan architecture, a server-focused design fabricated on TSMC's 7 nm process. It uses 8,300 million transistors across two 81 mm² chiplets, reflecting AMD's chiplet-based approach. The EPYC features 64 KB of L1 and 512 KB of L2 per core, but its 64 MB of shared L3 cache is substantially larger than Intel's 18 MB. It supports only DDR4 memory but over an eight-channel bus with 204.8 GB/s of bandwidth, and it offers 128 PCIe Gen 4 lanes versus Intel's 20 lanes.

Specification Differences

The two processors differ in nearly every core specification. The Intel Core i5-12600H has 12 cores and 16 threads, while the AMD EPYC 7203P has 8 cores and 16 threads. Intel's base clock is 2.70 GHz with a 4.50 GHz boost, while AMD runs at 2.80 GHz base and 3.40 GHz boost. The thermal design power differs dramatically: 45 watts for Intel versus 120 watts for AMD. Intel uses the BGA 1744 socket, while AMD uses SP3. The Intel chip is a mobile part, while AMD targets server/workstation. Intel includes integrated Iris Xe graphics; AMD has no integrated graphics. Memory support differs in both type (DDR4/DDR5 vs DDR4 only) and channel count (dual vs eight). Only AMD supports ECC memory. The EPYC has a launch MSRP of $348, while the Core i5-12600H has no listed launch MSRP.

Head-to-Head Benchmarks

The Cinebench suite shows a clear Intel sweep. In Cinebench R15 multicore, Intel scores 2,023 against AMD's 1,886, a 7.3% margin. The R15 single-core test shows 285 vs 266, a 7.1% Intel lead. These margins remain nearly constant across newer versions: R20 multicore gives Intel 8,430 vs 7,859 (7.3%), R20 single-core gives 1,189 vs 1,109 (7.2%), R23 multicore gives 20,072 vs 18,714 (7.3%), and R23 single-core gives 2,833 vs 2,642 (7.2%). This consistency suggests the Intel architecture has a structural advantage in both single-threaded and multi-threaded rendering workloads.

PassMark results reveal a more nuanced picture. The biggest Intel win is floating-point math at 38.4% (51,264 vs 37,049), followed by single-thread at 36.1% (3,453 vs 2,537). Integer math gives Intel a 6.1% edge (71,168 vs 67,083), and extended instructions are nearly tied at 0.3% (14,508 vs 14,466). The AMD EPYC counters with a dominant 51% win in prime number finding (145 vs 71), a 39.2% win in physics (2,077 vs 1,262), an 18.4% win in random string sorting (33,873 vs 27,653), a 15.1% win in data encryption (17,434 vs 14,799), and a 4% win in multithread (22,017 vs 21,128). Data compression is the closest AMD win at 2.7% (254,215 vs 247,404).

The benchmark data indicates that the Intel Core i5-12600H is the better choice for general-purpose computing, single-threaded applications, and floating-point-heavy workloads, while the AMD EPYC 7203P excels in memory-bandwidth-sensitive and cache-heavy server tasks. The EPYC's larger L3 cache and higher TDP enable its wins in encryption, physics, and prime number calculations, but the mobile Intel part's higher boost clock and hybrid architecture deliver superior performance in most user-facing benchmarks. The overall average benchmark scores (28,882 for Intel vs 28,583 for AMD) confirm that these are closely matched processors despite their completely different design philosophies.
