The largest Intel margin is in find prime numbers, where the AMD part scores 58 and the Intel part scores 358, a gap of 83.8%. Physics follows at 68.3%, with scores of 1022 and 3226. Floating point math shows a 54.9% gap, 50778 versus 112550. The multithread test is 35.2% in Intel's favor, 23858 versus 36811. Data encryption, extended instructions, random string sorting, and single-thread performance all favor Intel by margins between 21.4% and 31.7%. The closest result is integer math, where Intel leads by only 0.7%, 90882 versus 90270. The win count is 0 for AMD and 11 for Intel.

Where Each One Wins

Because the head-to-head set is one-sided, the use-case split is defined by workload type. Intel's largest advantages appear in prime number generation, physics, and floating-point math, which are compute-heavy tasks. Intel also leads in multithread by 35.2%, in encryption by 31.7%, and in extended instructions by 31.6%. AMD's only near-even result is integer math, where the Intel score of 90882 is just 0.7% above AMD's 90270.

The aggregate database metrics, however, favor AMD. The AMD part has an average benchmark score of 49196, compared to Intel's 44466, and a 90th percentile versus 88th. The AMD part's nearest rivals in average score are the AMD Ryzen 9 7900 at 49228, the Intel Core i5-14600KF at 49394, the Intel Core Ultra 5 245 at 48995, and the Intel Xeon Gold 5318H at 48698. The AMD part is 0.1% below the Ryzen 9 7900, 0.4% below the Core i5-14600KF, 0.4% above the Core Ultra 5 245, and 1% above the Xeon Gold 5318H.

The Intel part's nearest rivals are the AMD Ryzen 5 7500X3D at 44573, the Intel Core i9-13950HX at 44342, the AMD Ryzen AI Max 385 at 44309, and the Intel Core i5-13600 at 44240. The Intel part is 0.2% below the Ryzen 5 7500X3D, 0.3% above the Core i9-13950HX, 0.4% above the Ryzen AI Max 385, and 0.5% above the Core i5-13600.

Architecture Differences

The two processors are built around different architectures. AMD uses Zen 3, codename Cezanne, on a 7 nm process from TSMC, with 10,700 million transistors and a 180 mm² die. Intel uses Panther Lake, built on a 3 nm process at Intel; the database does not list transistor count or die size for Intel.

The core configurations differ in kind. AMD has 8 cores and 16 threads, while Intel has 16 cores and 16 threads. The cache hierarchy also differs. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3.

Integrated graphics differ as well. AMD uses Radeon Vega 8, while Intel uses Arc B390. Memory support follows the platform split. AMD supports DDR4 on a dual-channel bus with 51.2 GB/s of bandwidth. Intel supports LPDDR5X on a dual-channel bus with 153.6 GB/s. The PCIe implementation is also different: AMD uses Gen 3 with 16 CPU lanes, while Intel uses Gen 5 with 4 CPU lanes. AMD targets the desktop segment through AMD Socket AM4, while Intel targets the mobile segment through Intel BGA 2540.
