AMD EPYC 7203P vs Intel Core i9-12900H Comparison

Head-to-Head Benchmarks

The head-to-head data shows a clear split: the Intel Core i9-12900H wins 12 of 17 recorded benchmarks, while the AMD EPYC 7203P takes 5. However, the margins in those 5 wins are often decisive, and the Intel wins are not universal. The single largest gap belongs to the AMD part in Cinebench R23 single-core, where it scores 2642 against Intel's 1863.5, a 41.8% advantage. That is not a small edge; it is a dominant one. In the same test family, AMD also wins Cinebench R23 multi-core by 17.4%, scoring 18714 versus 15946.5.

The Intel part's biggest win is in PassMark floating point math, where it scores 67940 against AMD's 37049, a 45.5% lead. That is the largest margin in the entire comparison. Intel also leads in PassMark integer math by 28.5% (93828 vs 67083), PassMark single-thread by 31.7% (3717 vs 2537), and PassMark extended instructions by 23.4% (18875 vs 14466). These are substantial gaps, not marginal ones.

In Cinebench R15 and R20, the Intel part leads in multi-core: R15 multi-core shows 2576.5 versus 1886 (26.8% ahead), and R20 multi-core shows 9501 versus 7859 (17.3% ahead). The R20 single-core test also goes to Intel, 1341 versus 1109, a 17.3% lead. Interestingly, Cinebench R15 single-core is a dead tie at 266 for both parts, with the database crediting the win to AMD due to the 0 delta.

The remaining Intel wins are more modest: PassMark data compression (316714 vs 254215, 19.7% ahead), PassMark multithread (27340 vs 22017, 19.5% ahead), PassMark data encryption (18548 vs 17434, 6% ahead), and PassMark random string sorting (35296 vs 33873, 4% ahead). The AMD wins beyond the Cinebench R23 pair are PassMark find prime numbers (145 vs 107, 35.5% ahead) and PassMark physics (2077 vs 1753, 18.5% ahead).

The pattern is consistent: Intel dominates in raw arithmetic throughput and single-threaded workloads, while AMD takes the lead in Cinebench R23 (both single and multi-core) and in the prime number and physics subtests. The Intel part's single-thread advantage in PassMark is notable, but the AMD part's Cinebench R23 single-core win suggests the Zen 3 architecture handles that specific workload far better.

The Verdict

The data supports a clear conclusion: the Intel Core i9-12900H is the better all-around performer in the majority of recorded benchmarks, but the AMD EPYC 7203P is not a weak competitor. The Intel part wins 12 of 17 tests, and its margins in floating point math, integer math, and single-thread PassMark are large. The AMD part wins 5 tests, but two of those wins are by margins of 41.8% and 35.5%, which are the largest individual deltas in either direction.

For users prioritizing Cinebench R23 performance, whether single or multi-core, the AMD EPYC 7203P is the choice. For users prioritizing PassMark integer, floating point, or single-thread scores, the Intel Core i9-12900H is the choice. The Intel part also leads in data compression, encryption, extended instructions, multithread, and random string sorting, making it the more versatile option for general productivity workloads. The AMD part counters with wins in prime number finding and physics, which are specialized workloads.

Both parts sit at the 80th percentile among all CPUs in the database, and their average benchmark scores are close: the AMD part averages 28583, the Intel part averages 28003. The nearest rivals for the AMD part include the Intel Core 5 220H (average score 28574, 0% delta) and the AMD Ryzen 7 PRO 6850HS (28549, 0.1% delta). The Intel part's nearest rivals include the AMD Ryzen 5 PRO 5655G (28032, -0.1% delta) and the AMD Ryzen 5 PRO 8500GE (28054, -0.2% delta). This means both parts are firmly mid-pack in the broader CPU landscape, not outliers.

Architecture Differences

The AMD EPYC 7203P uses Zen 3 architecture under the codename Milan, part of the EPYC 7003 series. It is built on a 7 nm process by TSMC and has a die size of 2x 81 mm², with 8,300 million transistors. The Intel Core i9-12900H uses Alder Lake architecture (Alder Lake-H), built on a 10 nm process by Intel, with a die size of 217 mm². These are fundamentally different design philosophies: AMD uses a monolithic (or chiplet-based) server design, while Intel uses a hybrid mobile design.

The AMD part has 8 cores and 16 threads, while the Intel part has 14 cores and 20 threads. The Intel part's hybrid design likely explains its higher core count, though the AMD part's Zen 3 cores are more efficient per thread in certain workloads. The cache configurations differ sharply: the AMD part has 64 KB L1 per core, 512 KB L2 per core, and 64 MB shared L3. The Intel part has 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB shared L3. The AMD part's 64 MB L3 is more than double the Intel part's 24 MB, which likely contributes to its strong Cinebench R23 results.

Memory support also diverges: the AMD part supports DDR4 with an eight-channel memory bus and 204.8 GB/s bandwidth, plus ECC memory. The Intel part supports DDR4 and DDR5 with a dual-channel bus, no ECC, and no recorded bandwidth figure. The AMD part's eight-channel memory controller is a server-class feature, while the Intel part's dual-channel is typical for mobile. PCIe lanes also differ: the AMD part has 128 Gen 4 lanes, the Intel part has 20 Gen 4 lanes. The Intel part includes integrated graphics (Iris Xe 96EU), while the AMD part has none.

Specification Differences

The two parts differ in nearly every specification field. The AMD EPYC 7203P runs at a base clock of 2.80 GHz and a boost clock of 3.40 GHz, with a TDP of 120 W. The Intel Core i9-12900H runs at a base clock of 2.50 GHz and a boost clock of 5.00 GHz, with a TDP of 45 W. The Intel part's boost clock is significantly higher, and its TDP is less than half the AMD part's. The AMD part uses AMD Socket SP3, while the Intel part uses Intel BGA 1744. The AMD part's release date is September 4, 2023, while the Intel part's is January 3, 2022.

The AMD part has a launch MSRP of $348, which is listed in the database. The Intel part has no recorded launch MSRP. Both parts have locked multipliers. The AMD part's part number is 100-000001287100-100001287WOF, while the Intel part's is SRLD4. The AMD part is classified as Server/Workstation, while the Intel part is classified as Mobile. The AMD part's process node is 7 nm, the Intel part's is 10 nm. The AMD part's memory bus is eight-channel, the Intel part's is dual-channel. The AMD part supports ECC memory, the Intel part does not.

Where Each One Wins

The AMD EPYC 7203P wins in Cinebench R23 multi-core and single-core, PassMark find prime numbers, PassMark physics, and the Cinebench R15 single-core tie. These wins point to workloads that favor large shared cache and efficient core design. The 64 MB L3 cache and eight-channel memory bandwidth are server-class features that likely drive its strong Cinebench R23 performance. The prime number finding and physics wins suggest the Zen 3 architecture handles certain computational patterns better than Intel's hybrid design.

The Intel Core i9-12900H wins in Cinebench R15 and R20 multi-core, Cinebench R20 single-core, PassMark data compression, data encryption, extended instructions, floating point math, integer math, multithread, random string sorting, and single-thread tests. These wins cover the majority of general-purpose workloads: arithmetic, compression, encryption, and single-threaded responsiveness. The higher boost clock of 5.00 GHz and the larger per-core L2 cache (1.25 MB vs 512 KB) likely contribute to its PassMark single-thread advantage. The floating point math win is especially decisive at 45.5%, making this part the clear choice for number-crunching tasks that rely on floating point operations.

For users choosing between these two, the split is straightforward. Choose the AMD EPYC 7203P if the workload is dominated by Cinebench R23-style rendering or prime number/ physics computations, or if ECC memory and eight-channel bandwidth are requirements. Choose the Intel Core i9-12900H for general productivity, data compression, encryption, extended instruction sets, and single-threaded responsiveness. The Intel part's 45 W TDP also makes it more suitable for mobile use, while the AMD part's 120 W TDP and server socket target workstation or server deployments. The database shows both parts at the same 80th percentile, so neither is a clear overall winner; they win in different domains.
