AMD EPYC 7402P vs Intel Core i7-1165G7 Comparison

The AMD EPYC 7402P and Intel Core i7-1165G7 are fundamentally different processors, and the benchmark data reflects that chasm. The EPYC 7402P is a server-class behemoth that dominates in every multi-core and legacy single-core test, while the Core i7-1165G7 is a mobile chip that secures a single, notable victory in a modern single-threaded workload. Out of eight head-to-head comparisons, the EPYC 7402P wins seven, with its only loss coming in Geekbench single-core.

Head-to-Head Benchmarks

The most striking result is the sheer magnitude of the AMD EPYC 7402P's victories. In the Cinebench R23 multi-core test, the EPYC scores 37,195, while the Core i7-1165G7 manages only 8,293. This translates to a massive 348.5% lead for the AMD processor. This pattern repeats across the entire Cinebench suite: in R20 multi-core, the EPYC's 15,621 is 348.5% higher than the Intel's 3,483, and in R15 multi-core, the 3,749 versus 835 score gives the EPYC a 349% advantage. The margins are so consistent that they suggest a fundamental architectural advantage in raw throughput, not just a clock speed difference.

The single-core Cinebench results are equally lopsided, which is surprising given the Intel chip's higher boost clock. The EPYC 7402P scores 5,251 in Cinebench R23 single-core, compared to the Core i7-1165G7's 1,170, a 348.8% margin. In R20 single-core, the EPYC's 2,205 beats the Intel's 491 by 349.1%, and in R15 single-core, the 529 versus 117 score gives the EPYC a 352.1% edge. These results indicate that the EPYC's Zen 2 architecture delivers superior instructions per clock in these workloads, overwhelming the Intel part's higher 4.70 GHz boost clock with its 3.35 GHz.

However, the tables turn in the Geekbench single-core test. Here, the Intel Core i7-1165G7 scores 1,578, which is 23.7% ahead of the EPYC's 1,204. This is the only test where the Intel processor wins, and it highlights a specific strength in a particular type of single-threaded workload. The Geekbench multi-core test, by contrast, returns to form for the AMD part: the EPYC's 10,476 is 134.5% higher than the Intel's 4,467. The data shows a clear split: the EPYC dominates Cinebench entirely and Geekbench multi-core, while the Intel chip takes a narrow win in Geekbench single-core.

Architecture Differences

The two processors are built on fundamentally different architectures for different purposes. The AMD EPYC 7402P is built on the Zen 2 architecture, codenamed "Rome," using a 7 nm process from TSMC. It packs 24 cores and 48 threads, a configuration designed for heavy parallel workloads. The Intel Core i7-1165G7, in contrast, uses the Tiger Lake architecture, specifically "Willow Cove-U," on Intel's 10 nm process. It has only 4 cores and 8 threads, reflecting its mobile focus.

Cache configurations diverge sharply. The EPYC 7402P features 96 KB of L1 cache per core, 512 KB of L2 per core, and a massive 128 MB of shared L3 cache. The Core i7-1165G7 offers 80 KB of L1 per core, 1.25 MB of L2 per core, and just 12 MB of shared L3. The EPYC's 128 MB of L3 is a defining feature for server workloads that need to keep large datasets close to the cores.

Memory support is another major differentiator. The EPYC 7402P supports DDR4 memory with an eight-channel memory bus, providing a memory bandwidth of 204.8 GB/s. It also supports ECC memory, a critical feature for server reliability. The Core i7-1165G7 supports DDR4 and LPDDR4X on a dual-channel bus, with no listed memory bandwidth figure and no ECC support. PCIe lanes also differ dramatically: the EPYC provides 128 lanes of Gen 4, while the Intel chip offers only 4 lanes of Gen 4. The EPYC also has a larger die size at 74 mm² versus the Intel's 144 mm², despite having more cores.

Where Each One Wins

The AMD EPYC 7402P is the clear winner in any workload that can leverage multiple cores. Its 24 cores and 48 threads, combined with the 128 MB of L3 cache and eight-channel memory, make it ideal for server virtualization, database processing, and content creation that scales across cores. The Cinebench results, which show a consistent 348-352% advantage across all versions, underscore this dominance in rendering tasks. Its 65th percentile ranking among all CPUs, with an average benchmark score of 9,529, places it in the same performance tier as the Intel Core i7-7700HQ (0.4% delta) and Intel Xeon Platinum 8180 (1.3% delta), but the EPYC achieves this with far more cores.

The Intel Core i7-1165G7 wins in precisely one area: Geekbench single-core performance. Its 1,578 score is 23.7% higher than the EPYC's 1,204, indicating that it excels in lightly-threaded, latency-sensitive tasks. This makes it the better choice for quick, responsive single-application use on a laptop, where its 28 W TDP and integrated Iris Xe-LP Graphics G7 96EU are also practical advantages. The Intel chip's average benchmark score of 9,235 puts it at the 65th percentile as well, with rivals like the Intel Xeon Gold 5320 (0% delta) and AMD Ryzen Threadripper 3960X (-0.5% delta), but its wins are narrow and specific.

The Verdict

The data is unambiguous: the AMD EPYC 7402P is the superior processor for any multi-threaded or server-oriented task. It wins seven of eight head-to-head benchmarks, with margins of 134.5% to 352.1% in multi-core and Cinebench tests. Its 24 cores, 128 MB of L3 cache, eight-channel memory, and ECC support make it the only choice for workloads that demand raw parallel throughput and data integrity.

The Intel Core i7-1165G7 is the right pick only if your primary concern is a single specific type of single-threaded performance, as evidenced by its 23.7% Geekbench single-core win. Its 4 cores and 8 threads, 28 W TDP, and integrated graphics make it a mobile chip, but the benchmark data shows it cannot compete with the EPYC in any multi-core scenario. For a server or workstation, the EPYC 7402P is the definitive winner. For a laptop where single-threaded responsiveness is paramount, the Core i7-1165G7 has a narrow niche, but it is not a competitor in the same performance class.
