AMD EPYC 7272 vs Intel Core i7-12800HE Comparison

Head-to-Head Benchmarks

The benchmark database records a clean sweep for the Intel Core i7-12800HE across all six Cinebench tests. The Intel part wins every single head-to-head matchup, with margins that are remarkably consistent. In Cinebench R15 multi-core, the Intel scores 2253 against the AMD EPYC 7272's 2155, a 4.5% advantage. The single-core R15 test shows a similar story: 318 versus 304, a 4.6% lead.

Moving to Cinebench R20, the pattern holds. The Intel Core i7-12800HE posts 9391 in multi-core, while the EPYC 7272 manages 8982, again a 4.6% delta. Single-core R20 sees Intel at 1325 and AMD at 1267, another 4.6% gap. The most demanding workload, Cinebench R23, continues the trend: Intel scores 22360 multi-core and 3156 single-core, versus AMD's 21386 and 3019 respectively. The deltas are 4.6% and 4.5% in Intel's favor.

The consistency of these margins is notable. Across all six tests, the Intel lead never dips below 4.5% and never exceeds 4.6%. This suggests a systematic advantage rather than a workload-specific quirk. The average benchmark score in the database reinforces this: Intel's 6467 average sits above AMD's 6186, a difference that places the Intel part at the 62nd percentile of all CPUs, while the EPYC 7272 rests at the 61st percentile.

Looking at the nearest rivals in the database provides additional context. The Intel Core i7-12800HE's average score of 6467 puts it within 1% of the Intel Xeon D-2796TE (6510, -0.7%), the Xeon W-2191B (6531, -1%), and the Core i9-7960X (6533, -1%). It sits 1.2% ahead of the AMD EPYC 7551 (6391). The AMD EPYC 7272's average of 6186 is 0.6% ahead of the Core i9-7940X (6147) and 0.9% ahead of the EPYC 7501 (6128), but trails the Ryzen Threadripper 1950X (6231, -0.7%) and the Ryzen 3 3100U (6247, -1%). The database records 6 wins for Intel and 0 for AMD in this direct comparison.

The Verdict

The data is unambiguous: the Intel Core i7-12800HE is the faster processor in every benchmark recorded. If the decision rests purely on compute performance as measured by Cinebench, the Intel part is the clear choice. It leads by roughly 4.5% to 4.6% across single-core and multi-core workloads, a margin that is uniform and repeatable.

The AMD EPYC 7272, however, is not without its own rationale. The database shows it as a 12-core, 24-thread server processor with a 120W TDP, while the Intel part is a 14-core, 20-thread mobile chip with a 45W TDP. The EPYC belongs to a different market segment entirely: Server/Workstation versus Mobile. For anyone building a server platform that requires eight-channel memory support, ECC memory, and 128 PCIe Gen 4 lanes, the EPYC 7272 is the only one of these two that offers those features. The Intel part, by contrast, offers dual-channel memory, no ECC support, and 20 PCIe lanes.

So the verdict depends on context. For raw Cinebench throughput, pick the Intel Core i7-12800HE. For a server platform with specific enterprise requirements around memory channels, ECC, and PCIe lane count, the AMD EPYC 7272 is the database's only option with those features. The Intel part also carries a launch MSRP of $625 for the EPYC, but that figure is recorded only for the AMD product, not for the Intel mobile chip.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i7-12800HE is built on Intel's 10 nm process and uses the Alder Lake architecture, specifically the Alder Lake-H mobile variant. It features 14 cores and 20 threads, which indicates a hybrid configuration typical of Alder Lake: performance cores plus efficiency cores, though the database does not break down the core types. The die size is recorded at 217 mm². The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The base clock is 2.40 GHz with a boost clock of 4.60 GHz. It supports both DDR4 and DDR5 memory in a dual-channel configuration, lacks ECC memory support, and provides 20 PCIe Gen 4 lanes from the CPU. The integrated graphics is Iris Xe with 96 execution units, which is absent on the AMD part.

The AMD EPYC 7272 is a completely different beast. It uses TSMC's 7 nm process and the Zen 2 architecture under the Rome codename. The chip packs 12 cores and 24 threads, with a base clock of 2.90 GHz and a boost clock of 3.20 GHz. The transistor count is listed at 7,600 million, spread across two chiplets each measuring 74 mm², for a combined die size of 148 mm². The cache setup includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3 per die, totaling 64 MB of L3. Memory support is DDR4 only, but the memory bus is eight-channel, delivering a recorded memory bandwidth of 85.3 GB/s. ECC memory is supported. The PCIe implementation is far more expansive: 128 Gen 4 lanes from the CPU. There is no integrated graphics.

The process node difference is meaningful: 10 nm Intel versus 7 nm TSMC. The EPYC's lower core count but higher thread count (24 versus 20) suggests simultaneous multithreading on all cores, while the Intel part has 14 cores but only 20 threads, implying some cores lack SMT. The cache totals also differ: Intel has 24 MB of shared L3, while AMD has 64 MB total L3 across two dies. The memory bandwidth gap is substantial on paper, with AMD's eight-channel setup providing 85.3 GB/s versus Intel's unspecified dual-channel bandwidth, though the benchmark results do not directly test memory throughput.

Where Each One Wins

The Intel Core i7-12800HE wins on every Cinebench metric recorded in the database. Across multi-core and single-core tests in R15, R20, and R23, it posts higher scores with a consistent 4.5% to 4.6% margin. This makes it the stronger choice for any workload that relies on raw CPU throughput as measured by Cinebench, whether that is rendering, simulation, or general compute. Its higher boost clock of 4.60 GHz versus the EPYC's 3.20 GHz likely contributes to its single-core dominance, while its 14 cores and 24 MB of L3 cache help in multi-core scenarios despite having fewer threads than the AMD part. The Intel chip also offers integrated graphics, which the EPYC lacks, making it a more self-contained solution for systems that do not use a discrete GPU.

The AMD EPYC 7272 wins in the categories that are not measured by Cinebench. It offers eight-channel memory with 85.3 GB/s of bandwidth, ECC memory support, and 128 PCIe Gen 4 lanes. These are enterprise-class features that the Intel part simply does not have. For a server or workstation that needs to drive many PCIe devices, handle large memory footprints across eight channels, or require error-correcting memory for data integrity, the EPYC 7272 is the only option between these two. Its 24 threads also exceed the Intel part's 20 threads, which could benefit heavily threaded workloads that scale beyond Cinebench's test parameters. The EPYC's lower core count but higher thread count suggests a different threading model, and its 64 MB of total L3 cache is more than double Intel's 24 MB.

In practical terms, the Intel Core i7-12800HE is the performance winner in the recorded benchmarks, while the AMD EPYC 7272 is the platform winner for server-specific requirements. A mobile workstation or compact system would favor the Intel part for its 45W TDP and integrated graphics. A rack-mounted server or high-end workstation would favor the EPYC for its memory bandwidth, ECC support, and PCIe lane count. The database records 6 benchmark wins for Intel and 0 for AMD, but the feature set tells a different story for different use cases.
