Architecture Differences

The AMD EPYC 7453 is built on the Zen 3 architecture with the Milan codename, while the Intel Core i3-10105F uses the Comet Lake architecture with the Comet Lake-R codename. The EPYC 7453 is manufactured on a 7 nm process by TSMC, and the i3-10105F uses Intel's 14 nm process. This process gap directly influences power characteristics and transistor density, though the database does not list a transistor count for the i3.

The EPYC 7453 packs 28 cores and 56 threads, whereas the i3-10105F has 4 cores and 8 threads. Cache organization differs significantly: the EPYC provides 64 KB L1 per core, 512 KB L2 per core, and 64 MB shared L3. The i3 offers 64 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3. The EPYC's L3 cache is over ten times larger.

Memory architecture is another major split. The EPYC 7453 uses an eight-channel DDR4 memory bus with 204.8 GB/s bandwidth, and the i3-10105F uses a dual-channel DDR4 bus with 42.7 GB/s. ECC memory is supported only on the EPYC. PCIe connectivity also differs: the EPYC provides Gen 4 with 128 lanes, while the i3 provides Gen 3 with 16 lanes.

The socket and platform targets are distinct. The EPYC 7453 uses AMD Socket SP3 and is classified as a Server/Workstation part. The i3-10105F uses Intel Socket 1200 and is a Desktop part. The EPYC has a base clock of 2.75 GHz and boost clock of 3.45 GHz; the i3 has a base clock of 3.70 GHz and boost clock of 4.40 GHz. The EPYC's TDP is listed at 225, and the i3's TDP is 65. Neither processor has an unlocked multiplier, and neither includes integrated graphics.

The EPYC 7453's die is described as 4x 81 mm² with 16,600 million transistors. The i3-10105F has no die size or transistor count in the database. Both processors were released within one day of each other in March 2021, with the EPYC on March 14 and the i3 on March 15.

Head-to-Head Benchmarks

The benchmark data is uniformly one-sided. Across all six recorded Cinebench comparisons, the AMD EPYC 7453 wins every test, and the margin is remarkably consistent at roughly 446% to 447%.

The largest percentage gap appears in Cinebench R20 single-core. The EPYC 7453 scores 2,441, and the i3-10105F scores 446, producing a 447.3% delta. This is the only test where the delta exceeds 447%. The single-core advantage in absolute terms is 1,995 points.

Multi-core results show the same pattern with slightly smaller deltas. In Cinebench R20 multi-core, the EPYC scores 17,297 versus 3,165, a 446.5% difference. In Cinebench R23 multi-core, the EPYC scores 41,185 versus 7,537, a 446.4% delta. The EPYC's multi-core lead in absolute points is largest in R23, at 33,648 points.

Cinebench R15 tells the same story. Multi-core: EPYC 4,151 versus i3 759, a 446.9% delta. Single-core: EPYC 585 versus i3 107, a 446.7% delta. The absolute single-core margin in R15 is 478 points.

The percentiles for both CPUs are identical at 67, but this masks the scale of the head-to-head gap. The EPYC's average benchmark score of 11,912 places it near the Intel Core i7-7700 (11,914, 0% delta) and the AMD Ryzen 5 3500X (12,000, -0.7% delta). The i3-10105F's average of 12,644 places it near the Intel Atom x7809C (12,607, 0.3% delta) and the Intel Core i3-1215U (12,604, 0.3% delta). In direct comparison, the EPYC wins all 6 head-to-head matchups; the i3 wins none.

The Verdict

The data is unambiguous. The AMD EPYC 7453 outperforms the Intel Core i3-10105F in every recorded benchmark, with margins consistently above 446%. This is not a close contest, and there is no benchmark category where the i3 closes the gap.

The EPYC 7453 is the clear choice for any workload that benefits from its 28 cores, 56 threads, 64 MB L3 cache, or eight-channel memory bandwidth. Its 204.8 GB/s memory bandwidth is nearly five times the i3's 42.7 GB/s. Its 128 PCIe Gen 4 lanes versus the i3's 16 Gen 3 lanes makes it suited for systems with many high-speed devices.

The i3-10105F has the advantage in raw clock speeds: 4.40 GHz boost versus 3.45 GHz, and 3.70 GHz base versus 2.75 GHz. It also draws substantially less power, with a TDP of 65 versus 225. But the recorded benchmark data shows that the EPYC's architectural advantages in cores, cache, and memory bandwidth overwhelm the i3's clock speed edge, even in single-threaded Cinebench tests.

For a server or workstation platform, the EPYC 7453 is the only rational choice from these two. For a desktop system where the application cannot use more than 4 cores and where power draw is a primary concern, the i3-10105F remains an active product, but it will not match the EPYC in any measured Cinebench metric.

Where Each One Wins

AMD EPYC 7453 wins in:

• All Cinebench multi-core tests: R15 (4,151 vs 759), R20 (17,297 vs 3,165), R23 (41,185 vs 7,537)
• All Cinebench single-core tests: R15 (585 vs 107), R20 (2,441 vs 446), R23 (5,814 vs 1,064)
• Memory bandwidth: 204.8 GB/s vs 42.7 GB/s
• Memory channel count: eight-channel vs dual-channel
• L3 cache capacity: 64 MB vs 6 MB
• PCIe connectivity: Gen 4 with 128 lanes vs Gen 3 with 16 lanes
• ECC memory support: supported vs not supported
• Core and thread count: 28 cores/56 threads vs 4 cores/8 threads
• Process node: 7 nm vs 14 nm

Intel Core i3-10105F wins in:

• Base clock: 3.70 GHz vs 2.75 GHz
• Boost clock: 4.40 GHz vs 3.45 GHz
• TDP: 65 vs 225
• Average benchmark score: 12,644 vs 11,912 (though this is driven by different benchmark suites, not head-to-head tests)
• Desktop platform classification and lower launch MSRP of $97

The i3-10105F's wins are all in specifications that do not translate into any measured benchmark victory. Higher clock speeds do not overcome the EPYC's architectural lead, and the lower TDP is a power envelope difference, not a performance result. The average benchmark score difference reflects the broader test set for the i3, which includes PassMark and Geekbench tests not recorded for the EPYC; in the direct Cinebench comparisons, the EPYC wins every time.
