AMD EPYC 7702P vs Intel Core i7-9750H Comparison

The AMD EPYC 7702P and Intel Core i7-9750H occupy opposite ends of the computing spectrum, yet both land at the 69th percentile in the global CPU benchmark database. The EPYC 7702P is a 64-core server processor built on TSMC's 7 nm process, while the i7-9750H is a 6-core mobile chip on Intel's 14 nm node. Their head-to-head benchmark results are remarkably one-sided, with the EPYC 7702P winning all six recorded Cinebench tests by margins exceeding 480%. The average benchmark score for the EPYC 7702P is 15130, compared to 14886 for the i7-9750H, a 1.6% overall gap. However, the individual test deltas reveal a far more dramatic separation in raw throughput capabilities.

Head-to-Head Benchmarks

The Cinebench suite paints a stark picture of performance disparity. In Cinebench R15 multicore, the EPYC 7702P scores 5272 against the i7-9750H's 904, a 483.2% advantage. The single-core R15 test shows the EPYC at 744 versus 127, a 485.8% lead. These margins are nearly identical across all six tests, suggesting a consistent architectural advantage rather than workload-specific behavior.

Cinebench R20 multicore follows the same pattern: EPYC 7702P at 21969, i7-9750H at 3768, a 483% delta. The R20 single-core test shows 3101 against 531, a 484% gap. In Cinebench R23, the EPYC 7702P reaches 52308 multicore and 7384 single-core, while the i7-9750H manages 8973 and 1266 respectively, yielding deltas of 482.9% and 483.3%.

The consistency of these margins — all between 482.9% and 485.8% — indicates that the EPYC 7702P's advantage is structural. The EPYC has 64 cores and 128 threads versus 6 cores and 12 threads for the i7-9750H, a 10.67x core count ratio. Yet the performance delta in multicore tests is roughly 4.8x, meaning the i7-9750H is extracting more efficiency per core despite its older architecture. The single-core deltas being nearly identical to multicore deltas is unusual; typically, a high-core-count server chip loses ground in single-threaded workloads. Here, the EPYC 7702P's Zen 2 cores are so dominant that they overcome the i7-9750H's higher boost clock of 4.50 GHz versus 3.35 GHz.

Neither processor shows a win in any benchmark for the i7-9750H. The wins tally stands at 6 for the EPYC 7702P and 0 for the Intel part. This is not a close contest; it is a demonstration of how far server-grade silicon has outpaced mobile-class parts in raw compute throughput.

Architecture Differences

The EPYC 7702P uses AMD's Zen 2 architecture, codenamed Rome, built on a 7 nm process at TSMC with 3,800 million transistors on a 74 mm² die. The i7-9750H relies on Intel's Coffee Lake architecture, specifically Coffee Lake-HR, on a 14 nm process with a 149 mm² die. The process node difference alone explains a substantial portion of the performance gap, as the smaller 7 nm node allows for higher transistor density and better power efficiency.

Cache configurations diverge sharply. The EPYC 7702P provides 96 KB of L1 cache per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The i7-9750H offers 64 KB L1 per core, 256 KB L2 per core, and only 12 MB of shared L3. The EPYC's 256 MB L3 cache is over 21 times larger than the i7's 12 MB, which is critical for server workloads that repeatedly access large datasets.

Memory support also differs fundamentally. The EPYC 7702P uses eight-channel DDR4 memory with a bandwidth of 204.8 GB/s, while the i7-9750H uses dual-channel DDR4 with 42.7 GB/s. This 4.8x bandwidth advantage aligns closely with the multicore benchmark deltas, suggesting memory bandwidth is a primary performance driver. ECC memory is supported on the EPYC 7702P but not on the i7-9750H, reflecting their respective server and mobile market segments.

PCIe connectivity shows the EPYC 7702P with Gen 4 support versus Gen 3 on the i7-9750H. The i7-9750H includes integrated UHD 630 graphics, while the EPYC 7702P has no integrated graphics, relying on discrete GPUs or headless operation. The EPYC 7702P uses AMD Socket SP3, while the i7-9750H uses Intel BGA 1440, making them physically incompatible. Power envelopes differ drastically: the EPYC 7702P has a 200 W TDP versus 45 W for the i7-9750H, reflecting the server versus mobile design goals.

Where Each One Wins

The EPYC 7702P wins every recorded benchmark, but the nature of those wins points to specific use cases. Its 64 cores and 128 threads make it suited for heavily parallel workloads such as virtualization, database serving, and scientific computing. The 256 MB L3 cache and 204.8 GB/s eight-channel memory bandwidth support workloads that require rapid access to large in-memory datasets. The 7 nm Zen 2 architecture with 3,800 million transistors delivers high per-core performance, evidenced by the single-core Cinebench scores being over 480% higher than the i7-9750H's.

The i7-9750H, despite losing all head-to-head tests, has strengths in its own domain. Its 45 W TDP makes it suitable for laptops and compact systems where power and thermal limits are strict. The 4.50 GHz boost clock is higher than the EPYC's 3.35 GHz, which could benefit lightly threaded tasks that do not scale across many cores. The integrated UHD 630 graphics eliminate the need for a discrete GPU in basic display or media workloads. The 14 nm process, while older, is mature and widely deployed. The i7-9750H is end-of-life, while the EPYC 7702P remains active in production.

For a user prioritizing raw compute throughput, the EPYC 7702P is the clear choice. For a mobile system requiring moderate performance within a low power budget, the i7-9750H's 45 W TDP and integrated graphics make it functional despite its lower scores. The benchmark data does not show any scenario where the i7-9750H outperforms the EPYC 7702P, so the decision hinges on platform constraints rather than performance.
