AMD EPYC 74F3 vs Intel Core i3-10320 Comparison

This comparison pairs two CPUs that occupy completely different corners of the market: the AMD EPYC 74F3 is a 24-core server processor built for massive parallel workloads, while the Intel Core i3-10320 is a 4-core desktop chip aimed at everyday computing. The benchmark data shows a dominant performance gap, but the real question is which processor fits which use case. The answer depends almost entirely on the workload and platform requirements, not on raw score comparisons alone.

FAQ

Q: Which processor wins in multi-core rendering tests?

A: The AMD EPYC 74F3 wins every multi-core Cinebench test by a massive margin. In Cinebench R23 multi-core, the EPYC scores 51566 versus the i3-10320's 8486, a delta of 507.7%. The R20 multi-core test shows a similar gap: 21657 for the EPYC versus 3564 for the i3.

Q: Does the Intel Core i3-10320 have any benchmark advantage?

A: No. The head-to-head data shows the AMD EPYC 74F3 winning all 6 recorded benchmark comparisons, with the Intel Core i3-10320 recording 0 wins. The i3 does have additional PassMark tests in its benchmark list, but none of those appear in the head-to-head comparison.

Q: What are the single-core performance differences?

Q: Are these processors in the same performance percentile?

A: Yes, both CPUs have a percentileVsAllCpus of 69, meaning they rank at the same level relative to all CPUs in the database. This is despite their vastly different core counts and benchmark scores in specific tests.

The Verdict

The data makes one thing clear: the AMD EPYC 74F3 is the overwhelmingly faster processor in every head-to-head benchmark recorded. It wins all 6 comparisons, with deltas ranging from 507.6% to 510.8% across Cinebench R15, R20, and R23 in both single-core and multi-core tests. Anyone looking at raw compute performance should choose the EPYC 74F3 without hesitation.

However, the Intel Core i3-10320 serves a completely different purpose. It is a desktop processor with a 91 TDP, integrated graphics, and a dual-channel memory bus. The EPYC 74F3 pulls 240 TDP, requires an AMD Socket SP3 platform, and has no integrated graphics. The i3 is designed for basic desktop tasks, while the EPYC is built for server and workstation workloads.

The verdict from the data: pick the EPYC 74F3 if your workload demands massive parallel compute and you have the server platform to support it. Pick the i3-10320 if you need a simple desktop CPU with integrated graphics and modest power requirements. The percentile ranking of 69 for both suggests they are equally matched in the broader CPU landscape, but that similarity evaporates in actual benchmark results.

Head-to-Head Benchmarks

The benchmark results are one-sided, with the AMD EPYC 74F3 winning every recorded test. In Cinebench R15 multi-core, the EPYC scores 5197 against the i3's 855, a 507.8% advantage. The R15 single-core test shows 733 versus 120, a 510.8% delta. These margins are consistent across all tests, suggesting a fundamental performance gap rather than a workload-specific fluke.

Moving to Cinebench R20, the EPYC 74F3 scores 21657 in multi-core versus 3564 for the i3-10320, a 507.7% difference. Single-core R20 shows 3057 versus 503, a 507.8% delta. The R23 results follow the same pattern: multi-core 51566 versus 8486 (507.7%), single-core 7279 versus 1198 (507.6%).

The consistency of these deltas — all hovering around 507-511% — indicates that the EPYC 74F3's advantage is uniform across rendering workloads. The 24-core, 48-thread configuration of the EPYC completely overwhelms the 4-core, 8-thread i3. Even in single-core tests, where the i3's higher boost clock of 4.60 GHz might help, the EPYC's 4.00 GHz boost clock still delivers roughly 6x the performance. This suggests architectural efficiency differences beyond just core count.

The head-to-head data records all 6 wins for the AMD EPYC 74F3, with the Intel Core i3-10320 recording zero wins. The average benchmark scores are close (14915 versus 14852), but that aggregate hides the extreme disparity in the Cinebench tests where the EPYC dominates by over 500%.

Specification Differences

The two processors differ in nearly every specification. The AMD EPYC 74F3 has 24 cores and 48 threads, while the Intel Core i3-10320 has 4 cores and 8 threads. Base clocks are 2.80 GHz for the EPYC and 3.80 GHz for the i3, with boost clocks of 4.00 GHz and 4.60 GHz respectively.

Power draw differs substantially: the EPYC 74F3 has a TDP of 240, while the i3-10320 is rated at 91. The sockets are incompatible: AMD Socket SP3 for the EPYC, Intel Socket 1200 for the i3. Memory support shows the EPYC with eight-channel DDR4 and 204.8 GB/s bandwidth, versus dual-channel DDR4 with 42.7 GB/s for the i3.

PCIe capabilities diverge sharply. The EPYC 74F3 provides Gen 4 with 128 lanes (CPU only), while the i3-10320 offers Gen 3 with 16 lanes (CPU only). The EPYC supports ECC memory, while the i3 does not. The i3 includes integrated UHD Graphics 630, while the EPYC has no integrated graphics.

Market segments differ: the EPYC targets Server/Workstation, the i3 targets Desktop. The EPYC launched on 2021-03-14, the i3 on 2020-04-29. The EPYC has a launch MSRP of $2900, while the i3 has no recorded launch MSRP. The process nodes are 7 nm for the EPYC versus 14 nm for the i3, with the EPYC using TSMC as the foundry and the i3 using Intel.

Architecture Differences

The architectural gap between these two processors is fundamental. The AMD EPYC 74F3 uses Zen 3 architecture with the Milan codename, built on a 7 nm process at TSMC. The Intel Core i3-10320 uses Comet Lake architecture, built on a 14 nm process at Intel. This process difference explains part of the performance and efficiency gap.

Cache configurations are vastly different. The EPYC 74F3 has 64 KB L1 per core, 512 KB L2 per core, and 256 MB of shared L3 cache. The i3-10320 also has 64 KB L1 per core, but only 256 KB L2 per core and 8 MB of shared L3. The EPYC's 256 MB L3 is 32x larger than the i3's 8 MB, a critical factor for server workloads with large datasets.

The transistor count reinforces the scale difference. The EPYC 74F3 packs 33,200 million transistors across a 4x 81 mm² die configuration. The i3-10320 has no recorded transistor count or die size data. The EPYC's multi-die design with 24 cores requires significantly more silicon area.

Memory architecture also differs fundamentally. The EPYC 74F3 supports eight-channel DDR4 memory, enabling 204.8 GB/s bandwidth. The i3-10320 uses dual-channel DDR4 with 42.7 GB/s bandwidth. This 4.8x bandwidth advantage for the EPYC is crucial for memory-intensive server workloads.

The EPYC 74F3 supports ECC memory, a requirement for reliability in server environments. The i3-10320 does not support ECC. PCIe generations also differ: the EPYC uses Gen 4 with 128 lanes, while the i3 uses Gen 3 with 16 lanes. The EPYC's generation is EPYC (Zen 3 (Milan)), while the i3's is Core i3 (Comet Lake).

Where Each One Wins

The AMD EPYC 74F3 wins in every benchmark category recorded. Cinebench R15, R20, and R23 multi-core and single-core tests all go to the EPYC with deltas above 507%. The EPYC's 24 cores and 48 threads make it the clear choice for multi-threaded rendering, simulation, and server workloads. Its 256 MB L3 cache and eight-channel memory bandwidth support large datasets and high-concurrency environments.

The Intel Core i3-10320 has no benchmark wins in the head-to-head data, but it wins in platform suitability for desktop use cases. Its 91 TDP is far more manageable for standard desktop cooling, and its integrated UHD Graphics 630 eliminates the need for a discrete GPU. The i3's Intel Socket 1200 platform is mainstream, while the EPYC requires a server-grade SP3 motherboard.

The i3-10320 also carries additional PassMark benchmarks in its data, covering data compression (140255), data encryption (3458), extended instructions (9284), find prime numbers (32), floating point math (19483), integer math (31071), multithread (9982), physics (689), random string sorting (17821), and single thread (2841). These tests appear only for the i3, not in the head-to-head comparison, so they do not factor into the win count.

For a desktop user building a simple system, the i3-10320 wins on practicality: lower TDP, integrated graphics, and dual-channel memory are sufficient for everyday tasks. For a server or workstation user, the EPYC 74F3 wins decisively on raw compute, memory bandwidth, ECC support, and PCIe Gen 4 connectivity. The choice depends on platform needs, not benchmark scores, since the EPYC's 500%+ advantage is irrelevant to a user who only needs a basic desktop processor.
