AMD EPYC 7543P vs Intel Core 3 100U Comparison

The AMD EPYC 7543P and Intel Core 3 100U occupy entirely different corners of the processor market, and benchmark data confirms a complete mismatch in performance. Across every Cinebench workload measured, the EPYC 7543P delivers scores that are over 430% higher than the Core 3 100U, making the comparison less about competition and more about illustrating the gap between a 32-core server processor and a 6-core mobile chip. The data is unambiguous: the EPYC 7543P wins all six head-to-head benchmarks, with no test favoring the Intel part.

Architecture Differences

The two processors are built on fundamentally different architectures with distinct design goals. The AMD EPYC 7543P is part of the EPYC 7003 series, using the Zen 3 architecture codenamed Milan, fabricated on TSMC's 7 nm process. It houses 33,200 million transistors across 8x 81 mm² dies. The Intel Core 3 100U uses the Raptor Lake architecture codenamed Raptor Lake-U, built on Intel's 10 nm process.

Cache hierarchies diverge sharply. The EPYC 7543P offers 64 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Core 3 100U counters with 80 KB of L1 per core, 1.25 MB of L2 per core, but only 10 MB of shared L3. The EPYC's 256 MB L3 cache is 25 times larger than the Intel part's total.

Memory support reveals the server-versus-mobile split. The EPYC 7543P uses DDR4 with an eight-channel bus delivering 204.8 GB/s of bandwidth, while the Core 3 100U supports both DDR4 and DDR5 but only over a dual-channel bus. PCIe connectivity also differs drastically: the EPYC 7543P provides Gen 4 with 128 lanes, compared to the Core 3 100U's Gen 4 with 8 lanes. The EPYC supports ECC memory; the Core 3 does not. The Intel part includes integrated UHD Graphics 64EU, while the AMD chip has none.

Head-to-Head Benchmarks

The benchmark results paint a one-sided picture. The AMD EPYC 7543P wins all six Cinebench tests, with every delta exceeding 433%. In Cinebench R15 multi-core, the EPYC scores 5,713 against the Core 3's 1,070, a 433.9% advantage. The single-core R15 test shows 806 versus 150, a 437.3% delta, the largest margin of any test.

Moving to Cinebench R20, the EPYC 7543P posts 23,806 in multi-core versus 4,462 for the Core 3, a 433.5% gap. The R20 single-core result is 3,360 versus 629, a 434.2% difference. Cinebench R23 continues the pattern: multi-core shows 56,683 versus 10,624 (433.5%), and single-core shows 8,002 versus 1,499 (433.8%).

The consistency of these deltas is striking. Across all six tests, the performance ratio between the two processors remains nearly identical, ranging only from 433.5% to 437.3%. This suggests the EPYC 7543P's advantage is structural rather than workload-specific. The AMD processor's lead in single-core tests is particularly notable given the Core 3's higher 4.70 GHz boost clock versus the EPYC's 3.70 GHz, indicating that architectural efficiency and cache size outweigh raw clock speed.

The Verdict

The data leads to an obvious conclusion: the AMD EPYC 7543P is in a different performance class entirely. For any workload measured by Cinebench, the EPYC 7543P delivers more than five times the performance of the Intel Core 3 100U. The 433%+ deltas across single-core and multi-core tests leave no room for interpretation.

The Intel Core 3 100U's only advantages are its integrated graphics, lower 15 W TDP, and support for DDR5 memory. Its 4.70 GHz boost clock does not translate into benchmark wins, as the EPYC 7543P's 3.70 GHz clock still achieves over 430% higher scores in single-core tests. The EPYC's 32 cores and 64 threads dominate multi-core workloads, while its larger cache and superior memory bandwidth overcome the clock deficit in single-threaded tasks.

For a server or workstation workload, the EPYC 7543P is the only rational choice based on performance data. For a mobile or low-power system, the Core 3 100U is the only viable option given its socket and power profile, but buyers should understand it will deliver a small fraction of the EPYC's compute throughput.

Where Each One Wins

The AMD EPYC 7543P wins every benchmark in the comparison, making its use-case dominance absolute in the measured categories. In multi-core workloads such as Cinebench R23 multi-core, the EPYC's 56,683 score versus 10,624 demonstrates its capability for heavy parallel processing, rendering, and server virtualization. The 433.5% lead in multi-core extends across all tested Cinebench versions, confirming sustained advantage under load.

The EPYC 7543P also wins single-core tests despite its lower boost clock. Its 8,002 score in Cinebench R23 single-core versus 1,499 for the Core 3 shows that the combination of Zen 3 architecture, 256 MB L3 cache, and eight-channel memory bandwidth overcomes the Intel part's 1 GHz clock advantage. This makes the EPYC suitable for latency-sensitive single-threaded applications as well.

The Intel Core 3 100U's wins are not in benchmark scores but in platform attributes. Its integrated UHD Graphics 64EU allows for display output without a discrete GPU, an impossibility with the EPYC 7543P. The 15 W TDP versus 225 W makes the Core 3 suitable for battery-powered devices, and its dual-channel DDR4/DDR5 memory support offers flexibility in mobile designs. The 6-core, 8-thread configuration with a 4.70 GHz boost clock positions it for light productivity tasks, though the data shows it will deliver roughly a fifth of the EPYC's Cinebench performance. The Core 3's 10 MB L3 cache and 1.25 MB L2 per core are more than adequate for its intended mobile segment, but they cannot compensate for the EPYC's massive resource advantage.
