AMD EPYC 7203P vs Intel Core i5-12600 Comparison

The Intel Core i5-12600 and AMD EPYC 7203P sit at nearly identical overall average benchmark scores—28,646 for the Intel part versus 28,583 for the AMD part, a delta of just 0.2% in the Intel chip’s favor. That near-parity in aggregate, however, masks a dramatic split in workload behavior: the EPYC 7203P wins 13 of the 17 head-to-head tests, while the Core i5-12600 wins just 4, yet the Intel processor compensates with two enormous victories in specific math and single-thread tests. The data shows two very different design philosophies converging on the same average, which makes the choice between them entirely dependent on the application mix.

Head-to-Head Benchmarks

The AMD EPYC 7203P establishes its dominance in the Cinebench suite, winning every single render test by a narrow but consistent margin. In Cinebench R23 multi-core, the EPYC scores 18,714 against the i5-12600’s 18,105, a 3.3% lead. The single-core R23 result tells the same story: 2,642 for the EPYC versus 2,556 for Intel, again a 3.3% edge. This pattern repeats across R15 and R20, with the EPYC winning both multi-core and single-core variants by margins between 3.2% and 3.4%. The consistency of these deltas suggests a fundamental throughput advantage in the EPYC’s architecture that holds regardless of thread count scaling.

The PassMark suite reveals where the EPYC truly separates itself. In PassMark physics, the EPYC scores 2,077 versus Intel’s 1,365—a massive 34.3% lead. Random string sorting shows a 23.7% advantage for AMD (33,873 versus 25,832), and data encryption delivers a 25% win (17,434 versus 13,084). Prime number finding is the largest proportional gap: the EPYC scores 145 against Intel’s 83, a 42.8% advantage. Even in integer math, where the i5-12600 is competitive, the EPYC edges ahead 67,083 versus 66,123, a 1.4% margin. Data compression is essentially a tie, with the EPYC winning by just 0.8% (254,215 versus 252,160).

The Intel Core i5-12600 wins its four tests by much larger margins than the EPYC’s typical wins. The most striking is PassMark single-thread, where Intel scores 3,823 against AMD’s 2,537—a 50.7% advantage. Floating-point math shows Intel ahead 50,838 versus 37,049, a 37.2% lead. Extended instructions favor Intel by 17.7% (17,027 versus 14,466). These three wins are the largest deltas in the entire comparison, and they reveal a processor that is dramatically faster in specific instruction-heavy and single-core scenarios despite losing the overall benchmark count.

The Verdict

From the data, the AMD EPYC 7203P is the correct choice for anyone running a broad mix of multi-threaded server or workstation workloads. It wins every Cinebench render test, every PassMark test involving encryption, compression, prime numbers, physics, and string sorting, and it does so while maintaining a 0.2% higher average benchmark score than its Intel rival. The EPYC is the more consistent performer across the widest range of tests.

The Intel Core i5-12600 is the correct choice for workloads that depend heavily on single-thread performance or floating-point math. Its 50.7% single-thread advantage is not a marginal difference—it is a decisive separation that will translate to faster response times in lightly threaded applications. The 37.2% floating-point lead is equally significant for scientific computing or numerical analysis that does not scale perfectly across cores.

The overall average scores are nearly identical, with the i5-12600 at 28,646 and the EPYC at 28,583. This means that for a hypothetical workload that uses every test equally, the two processors are interchangeable. The choice must be driven by which specific tests matter most, not by the aggregate number.

Where Each One Wins

The Intel Core i5-12600 is the winner for single-threaded performance, as evidenced by its 50.7% lead in PassMark single-thread. It also dominates floating-point math with a 37.2% margin, making it the stronger choice for applications that rely on non-integer arithmetic. Extended instructions favor Intel by 17.7%, which suggests a benefit for workloads using advanced SIMD or specialized instruction sets.

The AMD EPYC 7203P wins in every other category. It is the winner for multi-threaded rendering, as shown by its 3.3% lead across all Cinebench versions. It is also the winner for encryption (25% ahead), random string sorting (23.7% ahead), and physics calculations (34.3% ahead). The prime number finding test shows the EPYC at 145 versus 83, a 42.8% advantage, indicating superior integer-based algorithmic throughput. The EPYC’s PassMark multi-thread score of 22,017 versus 21,399 for Intel reflects a 2.8% overall multi-threaded win.

Architecture Differences

The two processors come from fundamentally different design lineages. The Intel Core i5-12600 uses the Alder Lake architecture (codename Alder Lake-S) built on a 10 nm process at Intel’s own foundry. It has 6 cores and 12 threads, with a base clock of 3.30 GHz and a boost clock of 4.80 GHz. The die size is 163 mm². Its cache hierarchy consists of 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3.

The AMD EPYC 7203P uses the Zen 3 architecture (codename Milan) built on a 7 nm process at TSMC. It has 8 cores and 16 threads, with a base clock of 2.80 GHz and a boost clock of 3.40 GHz. The die is composed of two chiplets, each 81 mm², for a total of 162 mm². The EPYC packs 8,300 million transistors, and its cache design is markedly different: 64 KB of L1 per core, 512 KB of L2 per core, and a much larger 64 MB of shared L3.

The EPYC’s L3 cache is more than 3.5 times larger than the Intel part’s 18 MB, which likely contributes to its wins in encryption and string sorting. The Intel part’s higher boost clock (4.80 GHz versus 3.40 GHz) explains its massive single-thread advantage. The EPYC supports ECC memory, while the i5-12600 does not. The Intel part includes integrated graphics (UHD Graphics 770), while the EPYC has none.

Specification Differences

The two processors differ in nearly every major specification field. The Intel Core i5-12600 uses the Intel Socket 1700, while the AMD EPYC 7203P uses the AMD Socket SP3. The Intel part has 6 cores and 12 threads; the EPYC has 8 cores and 16 threads. Base clocks are 3.30 GHz for Intel versus 2.80 GHz for AMD, while boost clocks are 4.80 GHz versus 3.40 GHz. The TDP is 65 watts for the i5-12600 and 120 watts for the EPYC 7203P.

Memory support diverges sharply: the i5-12600 supports both DDR4 and DDR5 in a dual-channel configuration, while the EPYC supports only DDR4 but across eight channels with a memory bandwidth of 204.8 GB/s. The PCIe capabilities differ as well: the Intel part offers Gen 5 with 16 lanes (CPU only), while the EPYC offers Gen 4 with 128 lanes (CPU only). The market segments are distinct—Desktop for Intel, Server/Workstation for AMD—and the launch MSRP for the i5-12600 is $233, while the EPYC 7203P launched at $348. Both processors are active in production, and both have locked multipliers. The Intel part’s process node is 10 nm at Intel, while the EPYC uses 7 nm at TSMC, with the EPYC’s 8,300 million transistors versus no transistor count listed for Intel. The Intel die is 163 mm², while the EPYC uses two 81 mm² dies.
