AMD EPYC 7443 vs Intel Core i7-8750H Comparison

The AMD EPYC 7443 and Intel Core i7-8750H occupy opposite ends of the computing spectrum, yet their average benchmark scores place them as close rivals in this database. The EPYC 7443, a 24-core server processor, posts an average score of 13936, while the 6-core mobile i7-8750H averages 13868, a mere 0.5% difference. This statistical proximity, however, masks a dramatic divergence in workload characteristics. The data reveals a clear story: the EPYC 7443 dominates every head-to-head benchmark, while the i7-8750H’s inclusion in the same performance tier reflects the different ways these processors achieve their scores. This analysis will break down where each processor wins, the architectural chasm between them, and what the benchmark numbers actually mean for different use cases.

Where Each One Wins

The benchmark data is unambiguous: the AMD EPYC 7443 wins all six recorded head-to-head comparisons. In Cinebench R15, R20, and R23 — both single-core and multi-core variants — the EPYC 7443 emerges victorious with delta percentages hovering around 482%. This is not a marginal victory; it is a complete rout. The EPYC 7443’s multi-core scores are particularly dominant, with a Cinebench R23 multi-core score of 48183 versus the i7-8750H’s 8274. This suggests the EPYC 7443 is purpose-built for heavily threaded workloads like server virtualization, scientific computing, and content rendering that can utilize all 48 threads.

The Intel Core i7-8750H, conversely, wins zero head-to-head benchmarks. Its strength lies not in raw performance against this specific rival, but in its form factor and efficiency profile. As a 45W TDP mobile processor, it is designed for laptops where power draw and heat dissipation are critical constraints. Its 12 threads are sufficient for mainstream productivity tasks, gaming, and light content creation. The data shows the i7-8750H achieves its average score of 13868 through a different balance: it has additional benchmark entries beyond Cinebench, including Geekbench and Passmark tests, which may weight its average differently. Where the EPYC 7443 wins in absolute compute, the i7-8750H wins in deployability — it can fit in a slim chassis, which the EPYC 7443, with a 200W TDP and Socket SP3, cannot.

Architecture Differences

The architectural gap between these two processors is generational and fundamental. The EPYC 7443 is built on AMD’s Zen 3 architecture, codenamed Milan, using a 7 nm process node fabricated by TSMC. It features 24 cores and 48 threads, with a base clock of 2.85 GHz and a boost clock of 4.00 GHz. The chip contains 16,600 million transistors spread across a 4x 81 mm² die configuration. Its cache hierarchy is substantial: 64 KB of L1 per core, 512 KB of L2 per core, and a massive 128 MB of shared L3 cache. The EPYC 7443 supports eight-channel DDR4 memory with a bandwidth of 204.8 GB/s, and it includes ECC memory support. It also offers PCIe Gen 4 with 128 lanes from the CPU.

The i7-8750H, in contrast, is built on Intel’s Coffee Lake architecture, specifically Coffee Lake-H, using a 14 nm process node fabricated by Intel. It has 6 cores and 12 threads, with a base clock of 2.20 GHz and a boost clock of 4.10 GHz. The die size is 149 mm², and its cache is far smaller: 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3. Memory support is dual-channel DDR4, and there is no ECC support. The i7-8750H includes integrated graphics (UHD 630), which the EPYC 7443 lacks entirely. The i7-8750H is an end-of-life mobile part, while the EPYC 7443 is an active server/workstation part.

Head-to-Head Benchmarks

The Cinebench results are the only head-to-head metrics available, and they paint a picture of overwhelming EPYC dominance. In Cinebench R15 multi-core, the EPYC 7443 scores 4856 against the i7-8750H’s 834, a delta of 482.3%. The single-core R15 test shows a similar gap: 685 versus 117, a 485.5% difference. This pattern repeats across every iteration of Cinebench.

Moving to Cinebench R20 multi-core, the EPYC 7443 delivers 20236 points, while the i7-8750H manages 3475 — again a 482.3% lead. The R20 single-core test shows 2856 versus 490, a 482.9% delta. In Cinebench R23, the most demanding test, the multi-core scores are 48183 for the EPYC 7443 and 8274 for the i7-8750H, maintaining the exact 482.3% margin. The R23 single-core result is 6802 versus 1168, a 482.4% difference.

The consistency of the delta percentages (all hovering between 482.3% and 485.5%) is striking. It suggests that the performance gap is not workload-dependent but rather a fixed consequence of the core count and clock architecture. The EPYC 7443’s 24 cores and 48 threads provide exactly four times the core count, and the higher base clock of 2.85 GHz versus 2.20 GHz contributes to the additional margin. The i7-8750H’s boost clock of 4.10 GHz is slightly higher than the EPYC’s 4.00 GHz, but that advantage is insufficient to close the gap in any test.

Specification Differences

The specification sheet reveals fundamental differences beyond core counts. The EPYC 7443 has a TDP of 200W, while the i7-8750H is rated at 45W — a 155W difference that dictates entirely different cooling and power delivery requirements. The EPYC 7443 uses AMD Socket SP3, whereas the i7-8750H uses Intel BGA 1440, meaning the former is socketed for servers and the latter is soldered for mobile boards.

Memory architecture diverges sharply: the EPYC 7443 supports eight-channel DDR4 with a specified bandwidth of 204.8 GB/s, while the i7-8750H’s memory bus and bandwidth are not listed, indicating a dual-channel configuration typical of mobile parts. ECC memory is supported on the EPYC 7443 but not on the i7-8750H. PCIe capability is another differentiator: the EPYC 7443 offers Gen 4 with 128 lanes, while the i7-8750H has no PCIe specification listed, though it typically provides a limited number of Gen 3 lanes.

The EPYC 7443 has no integrated graphics; the i7-8750H includes UHD 630. Production status also differs: the EPYC 7443 is active, while the i7-8750H is end-of-life. The EPYC 7443 was released in March 2021 with a launch MSRP of $2010; the i7-8750H was released in April 2018 with no launch MSRP listed. Both processors have locked multipliers, preventing overclocking.
