AMD EPYC 7543 vs Intel Core i7-1260U Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive sweep in favor of the AMD EPYC 7543 across all six Cinebench comparisons. The EPYC 7543 wins every head-to-head test, with deltas ranging from 246.7% to 576.3%. These are not marginal differences; they reflect two processors engineered for entirely different operating contexts.

The largest gap appears in Cinebench R23 multi-core, where the EPYC 7543 scores 53,509 against the Core i7-1260U's 7,912.5, a 576.3% advantage. This is the most extreme delta in the dataset and underscores the EPYC's 32-core, 64-thread configuration versus the i7's 10-core, 12-thread layout. In Cinebench R20 multi-core, the EPYC 7543 posts 22,473 versus 4,736, a 374.5% lead. Cinebench R15 multi-core shows 5,393 versus 1,203, a 348.3% margin.

Single-core results tell a similar story, though with slightly smaller deltas. In Cinebench R23 single-core, the EPYC 7543 scores 7,554 versus 1,601, a 371.8% advantage. Cinebench R20 single-core shows 3,172 versus 668, a 374.9% lead. Cinebench R15 single-core records 761 versus 219.5, a 246.7% margin. Even where the Core i7-1260U's hybrid architecture might be expected to shine, the EPYC 7543's Zen 3 cores dominate every single-threaded test.

Contextualizing the EPYC 7543 within the broader database, its average benchmark score is 15,477, placing it at the 69th percentile among all CPUs. Its nearest rivals include the Intel Core 5 211TE at 15,370 (0.7% behind) and the AMD Ryzen 3 7440U at 15,682 (1.3% ahead). The Core i7-1260U, by contrast, has an average benchmark score of 16,320, placing it at the 70th percentile. Its nearest rivals include the AMD Ryzen 5 4600H at 16,341 (0.1% ahead) and the Intel Core i5-10600KF at 16,228 (0.6% behind). Interestingly, the Core i7-1260U's average score is higher than the EPYC 7543's average, yet in every Cinebench head-to-head test, the EPYC wins by enormous margins. This apparent contradiction stems from the fact that the Core i7-1260U has additional benchmark data points beyond Cinebench, including Geekbench and PassMark tests, which pull its average upward. The Cinebench suite, however, is the only common benchmark set shared between the two processors in the database.

The EPYC 7543's Cinebench R23 multi-core score of 53,509 is especially notable when compared against its nearest rivals in the database. The Intel Core 5 211TE, which sits 0.7% behind the EPYC in average score, does not approach this level of multi-threaded throughput. The EPYC's 64 threads provide a massive parallel workload advantage, and the recorded data confirms that advantage in every multi-core test.

FAQ

The Verdict

The data is unambiguous. The AMD EPYC 7543 is the correct choice for any workload that prioritizes raw multi-threaded throughput. Its 32 cores and 64 threads deliver Cinebench R23 multi-core performance that is 576.3% ahead of the Core i7-1260U. For server and workstation tasks that scale across many threads, the EPYC 7543 is overwhelmingly superior in every recorded Cinebench test.

The Intel Core i7-1260U, however, is not without its own positioning. Its average benchmark score of 16,320 is actually higher than the EPYC 7543's 15,477, and it sits at the 70th percentile versus the EPYC's 69th. This is because the i7-1260U has additional recorded benchmarks in Geekbench and PassMark, where it demonstrates capability in single-threaded and diverse workloads. Its integrated Iris Xe 96EU graphics and 9W TDP indicate a mobile-focused design, though the database does not record head-to-head comparisons in those tests against the EPYC.

Who should pick which? Organizations deploying server or workstation hardware with heavily parallel workloads should choose the EPYC 7543. Its Cinebench results are categorically dominant. Users seeking a mobile processor with a higher average benchmark score and integrated graphics should consider the Core i7-1260U, but only in contexts where the EPYC's massive multi-core advantage is not relevant. The recorded data does not support any scenario where the Core i7-1260U outperforms the EPYC 7543 in Cinebench, so any decision favoring the i7 must rest on factors outside those six tests.

Specification Differences

The AMD EPYC 7543 and Intel Core i7-1260U differ across nearly every hardware dimension. The EPYC 7543 has 32 cores and 64 threads, while the Core i7-1260U has 10 cores and 12 threads. Base clock speeds differ dramatically: the EPYC 7543 runs at 2.80 GHz, while the Core i7-1260U lists a base clock of 1100.00 MHz. Boost clocks reverse the trend somewhat, with the EPYC 7543 boosting to 3.70 GHz and the Core i7-1260U boosting to 4.70 GHz.

Thermal design power is another major divide. The EPYC 7543 has a TDP of 225W, while the Core i7-1260U has a TDP of 9W. This 216W difference reflects their respective market segments: the EPYC 7543 is a server/workstation processor, while the Core i7-1260U is a mobile processor.

Sockets differ entirely. The EPYC 7543 uses AMD Socket SP3, while the Core i7-1260U uses Intel BGA 1781. Memory support also diverges: the EPYC 7543 supports DDR4 with an eight-channel memory bus and a recorded memory bandwidth of 204.8 GB/s, while the Core i7-1260U supports DDR4 and DDR5 with a dual-channel bus and no recorded memory bandwidth figure. The EPYC 7543 supports ECC memory; the Core i7-1260U does not.

PCIe capabilities differ as well. The EPYC 7543 supports PCIe Gen 4 with 128 lanes (CPU only), while the Core i7-1260U supports PCIe Gen 4 without a recorded lane count. The Core i7-1260U includes integrated Iris Xe 96EU graphics; the EPYC 7543 has no integrated graphics. The EPYC 7543 has a launch MSRP of $3761. The Core i7-1260U has no recorded launch MSRP.

Architecture Differences

The two processors come from different architectural generations and manufacturers. The AMD EPYC 7543 is based on Zen 3 architecture with the codename Milan, part of the EPYC 7003 series. It is fabricated on a 7 nm process at TSMC, with 33,200 million transistors and a die size of 8x 81 mm². The Intel Core i7-1260U is based on Alder Lake architecture with the codename Alder Lake-U, fabricated on a 10 nm process at Intel. No transistor count or die size is recorded for the i7-1260U.

Cache hierarchies are structured differently. The EPYC 7543 has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 256 MB of shared L3 cache. The Core i7-1260U has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. The EPYC's 256 MB L3 cache is a defining feature for server workloads, providing a massive shared pool across its 32 cores.

The EPYC 7543 was released on 2021-03-14, while the Core i7-1260U was released on 2022-02-22. Both are listed as active in production. Neither processor has an unlocked multiplier. The EPYC 7543's market segment is Server/Workstation, while the Core i7-1260U's market segment is Mobile. The EPYC 7543's part number is 100-000000345100-100000345WOF; no part number is recorded for the Core i7-1260U.

The architectural differences explain the benchmark results. The EPYC 7543's Zen 3 cores, 32-core count, and 256 MB L3 cache are designed for sustained multi-threaded throughput. The Core i7-1260U's Alder Lake architecture, 10-core count, and 12 MB L3 cache are designed for mobile efficiency, with a 9W TDP and integrated graphics. The recorded Cinebench data shows that these architectural choices lead to a 576.3% multi-core advantage for the EPYC 7543, a gap that no other variable in the database can close.
