The Verdict

The data does not support a universal winner. The Intel Core i5-1240P is the clear choice for mobile systems and for workloads that resemble the majority of the recorded Cinebench tests. It wins 5 head-to-head comparisons, including all single-core tests and most multi-core tests. The AMD Ryzen 3 5300G is the better pick for a desktop build where Cinebench R23 multi-core matters most, because it wins that test by 17.8% and also carries a higher average benchmark score, 3303 versus 3202, plus a slightly better overall percentile, 54 versus 53. The platform context reinforces the split: AMD is a desktop part on Socket AM4 with an unlocked multiplier, while Intel is a mobile part on BGA 1744 with a locked multiplier. So the verdict depends on whether the target system is a desktop or a laptop, and which benchmark family is most representative of the user's workload.

Head-to-Head Benchmarks

The head-to-head results are lopsided in Intel's favor, but not uniformly. In Cinebench R15 multi-core, Intel scores 1566.5 against AMD's 1114, a 28.9% deficit for AMD. In R15 single-core, Intel's 226 beats AMD's 157 by 30.5%. The R20 tests show a similar pattern: Intel leads multi-core 5632 to 4645, a 17.5% margin, and single-core 795 to 655, a 17.6% margin. The R23 single-core test is close: Intel's 1600 edges AMD's 1561 by 2.4%. The one reversal is R23 multi-core, where AMD's 11060 tops Intel's 9392 by 17.8%. That single result gives AMD its only head-to-head win, and it is a substantial one, though Intel's R15 multi-core margin of 28.9% remains the largest in either direction. The pattern suggests that Intel's architecture dominates in the older Cinebench versions and in single-core tests, while AMD's Zen 3 design takes the lead specifically in the newer R23 multi-core workload.

Architecture Differences

The two chips come from different process nodes and foundries. AMD uses a 7 nm process from TSMC, while Intel uses a 10 nm process from Intel. AMD's die is 180 mm² and packs 10,700 million transistors; Intel's die is 217 mm², and the database does not list a transistor count. The core configurations diverge sharply: AMD has 4 cores and 8 threads, Intel has 12 cores and 16 threads. Cache hierarchies also differ. AMD provides 64 KB of L1 and 512 KB of L2 per core, plus 8 MB of L3. Intel provides 80 KB of L1 and 1.25 MB of L2 per core, plus 12 MB of shared L3. Memory support: AMD is limited to DDR4 with a recorded bandwidth of 51.2 GB/s; Intel supports both DDR4 and DDR5, with no bandwidth figure recorded. PCIe connectivity: AMD offers Gen 3 with 16 lanes, Intel offers Gen 4 with 20 lanes. Integrated graphics: AMD has Radeon Vega 6, Intel has Iris Xe 80EU. The platform context is also different: AMD is a desktop part on Socket AM4 with an unlocked multiplier, while Intel is a mobile part on BGA 1744 with a locked multiplier. TDPs reflect that: 65 for AMD, 28 for Intel. Base clocks are 4.00 for AMD and 1700.00 for Intel; boost clocks are 4.20 and 4.40. Release dates are 2021-04-12 for AMD and 2022-02-22 for Intel.

Where Each One Wins

Based on the recorded benchmarks, the AMD Ryzen 3 5300G wins in scenarios that resemble Cinebench R23 multi-core. It scores 11060 there, 17.8% ahead of Intel. It also has a higher average benchmark score, 3303 versus 3202, and a higher overall percentile, 54 versus 53. For a desktop system where that specific workload is important, and where an unlocked multiplier is desired, the AMD part is the data-backed choice. The Intel Core i5-1240P wins in every other recorded head-to-head test. It leads in Cinebench R15 multi-core by 28.9%, R15 single-core by 30.5%, R20 multi-core by 17.5%, R20 single-core by 17.6%, and R23 single-core by 2.4%. For mobile systems, or for workloads that align with those tests, Intel is the clear winner. The data also shows that Intel's single-core advantage shrinks in the newer R23 test, from 30.5% in R15 to 2.4% in R23, while AMD's multi-core advantage appears only in R23. This suggests the choice depends on which Cinebench version or workload family is most representative of the user's tasks.
