CPU Comparison

The Intel Core i3-12100F and AMD EPYC 7443 occupy opposite ends of the processor spectrum, yet both hold the 68th percentile in the global CPU benchmark database. The data shows a complete sweep for the EPYC 7443 across all six head-to-head Cinebench tests, with the Intel part trailing by a consistent 75.4% margin in every single measurement. The most striking disparity appears in Cinebench R23 multi-core, where the EPYC 7443 scores 48,183 versus the Core i3-12100F's 11,860, a 4x advantage that reflects the fundamental difference in core count and market positioning.

Head-to-Head Benchmarks

The AMD EPYC 7443 dominates every benchmark in the comparison set, with zero wins for the Intel Core i3-12100F. The pattern is remarkably uniform across all six tests, with the deltaPct holding steady at -75.4% for the Intel part in every case. This consistency suggests the performance gap is primarily structural, driven by core count and memory bandwidth, rather than workload-specific.

In Cinebench R23 single-core, the EPYC 7443 scores 6,802 against the i3-12100F's 1,674. That is a 75.4% deficit for Intel, which is surprising given that the i3-12100F has a higher boost clock of 4.30 GHz compared to the EPYC's 4.00 GHz. The single-core result indicates that architectural efficiency per clock, not just raw frequency, favors the Zen 3 design in this workload.

The multi-core results amplify the gap further. Cinebench R23 multi-core shows the EPYC 7443 at 48,183 versus 11,860 for the i3-12100F. With 24 cores and 48 threads against 4 cores and 8 threads, the EPYC's 6x core advantage translates to roughly a 4x score advantage, a scaling efficiency of about 67% when accounting for the additional threads. Cinebench R20 tells the same story: 20,236 for AMD versus 4,981 for Intel, again a 75.4% deficit for the i3-12100F.

Even in Cinebench R15, the oldest test in the suite, the pattern holds. The EPYC 7443 manages 4,856 multi-core points while the i3-12100F trails at 1,195. The single-core R15 result shows 685 versus 168, maintaining the exact same 75.4% delta. Notably, the i3-12100F's average benchmark score across all tests is 13,494, while the EPYC 7443 averages 13,936, a much narrower gap than the Cinebench results suggest, because the Intel part's benchmark pool includes 3DMark and PassMark tests where its per-thread performance is comparatively stronger.

The nearest rivals for each processor provide context. The i3-12100F sits within 1.1% of the Intel Core 3 N355, Intel Core 5 120UL, Core i5-9500, and Core i7-1250U. The EPYC 7443, meanwhile, trades blows with the AMD EPYC 7552 (-1.3%), Intel Core i5-10400 (-0.7%), Core i7-8750H (+0.5%), and Ryzen Threadripper PRO 3975WX (+1.1%). This suggests that despite the massive Cinebench disparity, both chips occupy similar overall benchmark territory when averaged across their respective test suites.

The Verdict

The data is unambiguous: the AMD EPYC 7443 wins every head-to-head benchmark by the same 75.4% margin. For workloads that scale with core count and memory bandwidth, rendering, scientific computing, virtualization, the EPYC 7443 is the only rational choice. Its 24 cores, 48 threads, and eight-channel memory bus provide the throughput that the 4-core, 8-thread i3-12100F cannot approach.

However, the i3-12100F is not without merit in this comparison. Its average benchmark score of 13,494 is within 3.2% of the EPYC 7443's 13,936, meaning that in mixed or lightly threaded workloads, the Intel part is far more competitive than the Cinebench results suggest. The i3-12100F achieves this with a 58 W TDP against the EPYC's 200 W, and it supports DDR4 and DDR5 memory while the EPYC is limited to DDR4.

The choice depends entirely on workload. For desktop use, gaming, or lightly threaded productivity, the i3-12100F's higher boost clock (4.30 GHz vs 4.00 GHz) and competitive average scores make it a viable option. For server or workstation deployments where multi-threaded throughput is paramount, the EPYC 7443's 4x Cinebench R23 multi-core advantage is decisive. The EPYC also offers ECC memory support, 128 PCIe Gen 4 lanes, and 128 MB of L3 cache, features the i3-12100F lacks entirely.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i3-12100F uses Alder Lake architecture on a 10 nm process node from Intel's own foundry, while the AMD EPYC 7443 uses Zen 3 architecture on a 7 nm node fabricated by TSMC. The EPYC's 7 nm process gives it a transistor density advantage, with 16,600 million transistors spread across four 81 mm² dies, compared to the i3-12100F's single 163 mm² die (transistor count not specified).

Cache hierarchy differs substantially. The i3-12100F provides 80 KB of L1 cache per core and 1.25 MB of L2 per core, with 12 MB of shared L3. The EPYC 7443 offers 64 KB L1 per core and 512 KB L2 per core, but compensates with 128 MB of shared L3, more than 10x the Intel part's L3 capacity. This massive L3 pool is critical for server workloads that repeatedly access large datasets.

Memory architecture represents another major divergence. The i3-12100F uses a dual-channel memory bus supporting both DDR4 and DDR5, while the EPYC 7443 uses an eight-channel DDR4 bus with a rated bandwidth of 204.8 GB/s. The EPYC also supports ECC memory, which the i3-12100F does not. PCIe connectivity differs as well: the Intel part offers Gen 5 with 16 CPU lanes, while the EPYC provides Gen 4 with 128 CPU lanes, favoring the server part for I/O-heavy applications.

The EPYC 7443's release date of March 2021 places it in the EPYC 7003 series (Milan generation), while the i3-12100F belongs to the Core 12th Gen (Alder Lake-S) family. Both are currently listed as Active in production.

Specification Differences

The core and thread counts are the most obvious differentiators: the i3-12100F has 4 cores and 8 threads, while the EPYC 7443 has 24 cores and 48 threads. Base clocks are 3.30 GHz for Intel versus 2.85 GHz for AMD, with boost clocks of 4.30 GHz and 4.00 GHz respectively. The i3-12100F's TDP of 58 W is dramatically lower than the EPYC 7443's 200 W.

Socket compatibility is entirely separate: the i3-12100F uses Intel Socket 1700, while the EPYC 7443 uses AMD Socket SP3. Process nodes differ (10 nm Intel vs 7 nm TSMC), as do die sizes (163 mm² single die vs 4x 81 mm²). The EPYC's transistor count of 16,600 million has no equivalent figure for the i3-12100F.

Cache specifications diverge across all levels. L1 is 80 KB per core for Intel versus 64 KB per core for AMD. L2 is 1.25 MB per core for Intel versus 512 KB per core for AMD. L3 is 12 MB shared for Intel versus 128 MB shared for AMD. ECC memory support is present on the EPYC but absent on the i3-12100F. PCIe capabilities favor the EPYC with 128 Gen 4 lanes against the i3-12100F's 16 Gen 5 lanes. Memory channels are eight for AMD versus two for Intel.

The launch MSRP reflects their positioning: the i3-12100F launched at $97, while the EPYC 7443 launched at $2010. Neither processor has an unlocked multiplier or integrated graphics. The part numbers are SRL63 for Intel and 100-000000340100-100000340WOF for AMD.
