CPU Comparison

The Intel Core i7-12700E and the AMD EPYC 72F3 occupy different corners of the processor market, yet their benchmark scores place them remarkably close in raw compute capability. The Core i7-12700E, a 12-core Alder Lake desktop part, and the EPYC 72F3, an 8-core Zen 3 server chip, both sit at the 62nd percentile among all CPUs. Their average benchmark scores are nearly identical: 6776 for the Intel part versus 6700 for the AMD part. This parity makes the choice between them less about overall speed and more about the specific platform requirements, memory capabilities, and workload characteristics each processor brings to the table.

FAQ

Q: Which processor has the higher average benchmark score?

A: The Intel Core i7-12700E holds a slight edge in average benchmark score at 6776, compared to the AMD EPYC 72F3’s 6700. This difference of 76 points is minimal, representing roughly a 1.1% gap.

Q: How do the two processors compare in multi-core Cinebench R23 performance?

A: The Intel Core i7-12700E scores 23879 in Cinebench R23 multi-core, while the AMD EPYC 72F3 scores 23164. The Intel processor holds a 3.1% advantage in this test.

Q: What is the difference in single-core performance between the two?

A: The Intel Core i7-12700E leads in every single-core benchmark recorded. In Cinebench R23 single-core, it scores 3371 versus the EPYC 72F3’s 3270, a 3.1% difference. The margin is similar in Cinebench R15 single-core, with Intel at 339 and AMD at 329.

Q: Do both processors support ECC memory?

A: No. The AMD EPYC 72F3 supports ECC memory, while the Intel Core i7-12700E does not. The AMD part also features an eight-channel memory bus, whereas the Intel processor uses a dual-channel configuration.

Q: What are the available PCIe lanes for each processor?

A: The AMD EPYC 72F3 provides 128 PCIe Gen 4 lanes (CPU only). The Intel Core i7-12700E offers 20 PCIe Gen 5 lanes (CPU only).

Q: Which processor has a higher base clock speed?

A: The AMD EPYC 72F3 has a significantly higher base clock of 3.70 GHz, compared to the Intel Core i7-12700E’s 2.10 GHz. However, the Intel part boosts higher, reaching 4.80 GHz versus the EPYC’s 4.10 GHz.

The Verdict

The data presents a clear performance winner: the Intel Core i7-12700E takes all six head-to-head benchmark comparisons. The margins are consistent, hovering around 3% in favor of Intel across both multi-core and single-core Cinebench tests. For users whose primary metric is raw Cinebench performance, the Intel part is the straightforward choice.

However, the EPYC 72F3 is not without its own clear rationale. It is the only option here with ECC memory support, a feature critical for data integrity in server environments. Its eight-channel memory bus and 204.8 GB/s memory bandwidth dwarf the Intel part’s dual-channel setup, making it the superior choice for memory-bandwidth-intensive workloads. The EPYC also offers 128 PCIe Gen 4 lanes versus Intel’s 20 Gen 5 lanes, providing far more expansion and I/O capacity for multi-GPU or storage-heavy server configurations. The EPYC is a server/workstation component; the Intel is a desktop component. Pick the Intel for general compute wins, pick the EPYC for a server platform that demands ECC, massive memory throughput, and extensive PCIe connectivity.

Head-to-Head Benchmarks

The benchmark results are uniformly in favor of the Intel Core i7-12700E, but the margins tell a story of parity rather than dominance. In the Cinebench R15 multi-core test, Intel scores 2406 against AMD’s 2334, a 3.1% lead. The single-core R15 test shows a similar pattern, with Intel at 339 and AMD at 329, a 3% advantage.

Moving to the more demanding Cinebench R20 suite, the Intel processor continues its sweep. It scores 10029 in multi-core versus the EPYC’s 9728, again a 3.1% delta. In single-core R20, Intel posts 1415 against AMD’s 1373, maintaining that 3.1% margin. The Cinebench R23 results, which represent the heaviest sustained load in this dataset, show Intel at 23879 multi-core and 3371 single-core, while AMD trails at 23164 and 3270 respectively. The delta remains a consistent 3.1% across these final tests.

It is worth noting that the EPYC 72F3’s nearest rivals in the overall database include the Intel Xeon Gold 5317 and Intel Xeon D-2775TE, with delta percentages of -0.1% and -0.2% respectively. This places the EPYC in the same performance tier as those Xeon parts. The Core i7-12700E’s nearest rivals include the AMD Ryzen Threadripper 2970WX and the Intel Xeon Gold 6154, with deltas of 0.2% and -0.4%. These rival comparisons reinforce the idea that both CPUs are clustered in a narrow performance band, despite their architectural differences.

Specification Differences

The core and thread counts differ substantially. The Intel Core i7-12700E features 12 cores and 20 threads, while the AMD EPYC 72F3 has 8 cores and 16 threads. This gives Intel a 50% advantage in core count and a 25% advantage in thread count, which contributes to its multi-core wins despite the EPYC’s higher clock speeds.

Clock speeds are a point of divergence. The EPYC 72F3 has a base clock of 3.70 GHz, far higher than the Core i7-12700E’s 2.10 GHz. Yet the Intel part’s boost clock of 4.80 GHz exceeds the EPYC’s 4.10 GHz. This indicates that the EPYC is designed for sustained, high-frequency operation at its base, while the Intel chip relies on aggressive boosting to achieve its performance.

Thermal design power (TDP) is another major differentiator. The Intel Core i7-12700E is rated at 65W TDP, while the AMD EPYC 72F3 is rated at 180W. This nearly 3x difference in TDP reflects the EPYC’s server-oriented power envelope. The Intel part uses the Intel Socket 1700, while the AMD part uses the AMD Socket SP3. Memory support differs as well: the Intel processor supports both DDR4 and DDR5, whereas the EPYC supports only DDR4.

Architecture Differences

The two processors are built on fundamentally different architectures. The Intel Core i7-12700E uses the Alder Lake architecture, specifically the Alder Lake-S codename from the Core 12th Gen series. It is manufactured on Intel’s 10 nm process node with a die size of 215 mm². In contrast, the AMD EPYC 72F3 uses the Zen 3 architecture with the Milan codename, built on TSMC’s 7 nm node. The EPYC’s die configuration is notably different, consisting of 8x 81 mm² chiplets, and it contains 33,200 million transistors.

Cache hierarchies also reveal different design philosophies. The Intel chip has an 80 KB L1 cache per core, a 1.25 MB L2 cache per core, and a 25 MB shared L3 cache. The AMD chip has a smaller 64 KB L1 and 512 KB L2 per core, but a massive 256 MB shared L3 cache. This 10x difference in L3 cache size is a hallmark of the EPYC’s server design, aimed at keeping large working sets resident on-chip.

The Intel part includes integrated graphics in the form of UHD Graphics 770, while the AMD EPYC 72F3 has no integrated graphics. The EPYC compensates with 128 PCIe Gen 4 lanes versus Intel’s 20 Gen 5 lanes. The Intel part supports dual-channel memory, while the EPYC supports eight-channel memory with a specified bandwidth of 204.8 GB/s. The EPYC also has ECC memory support, which the Intel part lacks. The market segments are clear: Intel targets Desktop, while AMD targets Server/Workstation.

Where Each One Wins

The Intel Core i7-12700E wins in every benchmark category recorded, making it the pick for applications that rely on Cinebench-style rendering and processing workloads. Its higher core count and superior single-core speed give it the edge in both heavily threaded and lightly threaded tasks. The 3.1% consistent lead across all tests suggests a well-rounded performance advantage. The Intel part’s lower 65W TDP also makes it a more power-efficient option, and its support for both DDR4 and DDR5 memory offers platform flexibility.

The AMD EPYC 72F3 wins in platform features rather than raw benchmark scores. Its ECC memory support is indispensable for error-sensitive server workloads. The eight-channel memory bus and 204.8 GB/s bandwidth make it the superior choice for memory-bound applications like large database caches or in-memory analytics. The 128 PCIe Gen 4 lanes allow for far more expansion cards, NVMe drives, or accelerators than the Intel part’s 20 Gen 5 lanes. The EPYC’s 256 MB L3 cache is also a significant advantage for workloads with large, reusable datasets that fit within that cache. While it loses every benchmark here, the EPYC 72F3 is built for a different class of system, where data integrity, memory throughput, and I/O scalability outrank raw Cinebench scores.
