AMD EPYC 7502P vs Intel Core i3-1305U Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core i3-1305U and the AMD EPYC 7502P is decisively one-sided. Across all six recorded Cinebench tests, the EPYC 7502P takes the win, with the Intel part trailing by margins that consistently hover around 83%. In Cinebench R23 multi-core, the EPYC scores 43395 against the i3-1305U's 7183, a delta of -83.4%. The single-core R23 result shows a similar pattern: the EPYC posts 6126, while the i3-1305U manages 1014, again a -83.4% gap.

Looking at the older R20 suite, the story repeats. The EPYC 7502P delivers 18225 in multi-core versus 3016 for the i3-1305U (-83.5%). In R20 single-core, the EPYC scores 2572, and the i3-1305U reaches only 425, also a -83.5% delta. The R15 tests follow the same trajectory: the EPYC wins multi-core with 4374 against 723, and single-core with 617 against 102, both at -83.5%.

The consistency of the delta across every test is striking. It suggests the performance gap is not workload-specific but fundamental to the designs of the two processors. The i3-1305U wins zero head-to-head tests, while the EPYC 7502P wins all six. The average benchmark score for the i3-1305U is 11200, placing it at the 66th percentile of all CPUs. The EPYC 7502P has an average score of 10512, also at the 66th percentile. Despite the EPYC's overwhelming victory in these direct comparisons, the average scores and percentiles are close, which indicates the i3-1305U benefits from a different set of benchmarks in its profile.

The nearest rivals for the i3-1305U include the Intel Xeon Gold 6336Y (avg score 11191, delta 0.1%), the AMD Ryzen 5 3500U (11176, delta 0.2%), and the AMD EPYC 7542 (11152, delta 0.4%). Its closest competitor on the negative side is the AMD EPYC 7452 (11279, delta -0.7%). For the EPYC 7502P, the nearest rivals are the AMD EPYC 7D12 (10547, delta -0.3%), the Intel Core i7-4790 (10556, delta -0.4%), and on the positive side, the Intel Xeon W-3175X (10369, delta 1.4%) and the Intel Xeon Gold 6338N (10347, delta 1.6%). These figures show that while the EPYC 7502P is far ahead of the i3-1305U in the tested workloads, it sits in a competitive field among server and high-end desktop parts.

Architecture Differences

The two processors come from entirely different design philosophies. The Intel Core i3-1305U is a mobile part built on Raptor Lake architecture, specifically Raptor Lake-U, using a 10 nm process from Intel's own foundry. It has 5 cores and 6 threads. The AMD EPYC 7502P is a server processor from the EPYC 7002 series, based on Zen 2 architecture with the codename Rome, manufactured on a 7 nm process by TSMC. It packs 32 cores and 64 threads.

The cache layouts differ substantially. The i3-1305U has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. The EPYC 7502P has 96 KB of L1 per core, 512 KB of L2 per core, and a massive 128 MB of shared L3. That L3 difference is critical for workloads that rely on large working sets residing in cache.

Memory support also separates them. The i3-1305U supports DDR4 and DDR5 in a dual-channel configuration. The EPYC 7502P supports only DDR4, but with an eight-channel memory bus and a recorded memory bandwidth of 204.8 GB/s. The EPYC also supports ECC memory, while the i3-1305U does not. In terms of PCIe, the i3-1305U offers Gen 4 with 8 lanes (CPU only), while the EPYC 7502P provides Gen 4 without a lane count specified in the data.

The i3-1305U includes integrated graphics: UHD Graphics 64EU. The EPYC 7502P has no integrated graphics at all. The i3-1305U has a base clock of 1600 MHz and a boost clock of 4.50 GHz, with a TDP of 15 W. The EPYC 7502P runs at a base of 2.50 GHz and boosts to 3.35 GHz, with a TDP of 180 W. The EPYC's transistor count is listed at 3,800 million, with a die size of 74 mm². No transistor or die size data is recorded for the i3-1305U.

The release dates differ by over three years: the i3-1305U launched on 2023-01-03, while the EPYC 7502P launched on 2019-08-06. Both are listed as Active in production status. The i3-1305U has a launch MSRP of $309; the EPYC 7502P has no launch MSRP recorded. Neither chip has an unlocked multiplier.

Where Each One Wins

The data shows a clear split based on workload type and platform. The EPYC 7502P wins every Cinebench test in the head-to-head comparison, which covers both multi-core and single-core rendering workloads. The multi-core advantage is enormous: in R23, the EPYC scores 43395 versus 7183, making it more than six times faster in that specific test. This is the expected outcome for a 32-core, 64-thread server chip against a 5-core, 6-thread mobile chip.

Single-core results also favor the EPYC, but the margin is proportionally similar. In R23 single-core, the EPYC scores 6126 against 1014, which is still a -83.4% delta. This indicates that even on a per-thread basis, the higher-clocked EPYC (boost 3.35 GHz) outperforms the i3-1305U (boost 4.50 GHz) in these tests, likely due to architectural efficiency and cache size.

However, the i3-1305U has its own strengths outside the head-to-head tests. Its benchmark profile includes PassMark tests where it shows solid scores: data compression at 92767, data encryption at 5895, extended instructions at 5240, floating point math at 19687, integer math at 27925, multithread at 8747, physics at 523, and random string sorting at 10889. The single-thread PassMark score is 3115. These numbers are not directly compared with the EPYC, but they indicate that the i3-1305U is a capable mobile processor for everyday tasks and light productivity.

The EPYC 7502P has a Geekbench score of 7822 multi-core and 963 single-core, which are not part of the head-to-head table but show its broader performance envelope. The i3-1305U's average benchmark score of 11200 is actually higher than the EPYC's 10512, which suggests that when all benchmarks are averaged, the i3-1305U performs competitively in its own category. This is because the i3-1305U's benchmark suite includes many PassMark tests that reward its strong single-thread performance and integrated features.

The Verdict

Choosing between these two processors is a matter of platform and intent, not raw performance alone. The EPYC 7502P is the clear winner in every recorded head-to-head benchmark, with a -83.4% to -83.5% delta across all Cinebench tests. For any application that relies on Cinebench-style rendering, the EPYC dominates. Its 32 cores, 64 threads, 128 MB of L3 cache, and eight-channel DDR4 memory with 204.8 GB/s bandwidth make it a server-class workhorse. The i3-1305U cannot compete in these workloads.

Yet the i3-1305U is a mobile processor with a 15 W TDP, integrated UHD Graphics 64EU, and support for DDR4 and DDR5. It is designed for laptops and compact systems where power efficiency and integrated graphics matter. Its higher boost clock of 4.50 GHz and its PassMark scores, such as 92767 in data compression, show it handles everyday tasks well. The EPYC 7502P has no integrated graphics, requires a discrete GPU, and has a 180 W TDP, which is not suitable for mobile use.

The data does not support a single "best" choice. For a server or workstation that runs multi-threaded rendering, the EPYC 7502P is the only logical pick. For a portable system that needs to run general applications, the i3-1305U is the appropriate part. The fact that both sit at the 66th percentile of all CPUs in average benchmark score is a reminder that percentile rankings can obscure massive differences in specific workloads. The recorded data shows the EPYC is overwhelmingly faster in Cinebench, but the i3-1305U has a broader benchmark profile that includes tasks where it performs well. The verdict is simple: pick the EPYC for server workloads, pick the i3-1305U for mobile use, and do not expect either to substitute for the other.
