AMD Ryzen 3 4300G vs Intel Core i3-1315U Comparison

Head-to-Head Benchmarks

The Intel Core i3-1315U dominates this matchup, winning 13 of the 17 recorded benchmark comparisons. Its most decisive victories come in single-threaded and math-heavy workloads. In PassMark single-thread testing, the Intel part scores 3380 against the AMD Ryzen 3 4300G's 2425, a 39.4% advantage. The gap is even more pronounced in Prime Number search, where Intel scores 41 versus AMD's 20, a 105% lead. Floating Point Math shows Intel at 27012 against AMD's 17577, a 53.7% margin, while Physics simulation favors Intel by 55.5% (706 versus 454).

Cinebench results tell a consistent story. Across all three Cinebench versions (R15, R20, and R23), Intel leads by roughly 11.7% to 11.8% in both single-core and multi-core tests. For example, Cinebench R23 multicore shows Intel at 9374 versus AMD's 8387, while the single-core test shows 1323 against 1184. The margin is remarkably uniform across the entire Cinebench suite, suggesting a consistent architectural advantage rather than workload-specific behavior.

The AMD Ryzen 3 4300G does carve out four wins, but they are narrower and clustered in specific task types. Data Compression favors AMD by 8.2% (137681 versus 126436), Data Encryption by 7.3% (8176 versus 7583), Extended Instructions by 19% (9148 versus 7413), and Random String Sorting by a slim 3.3% (14503 versus 14028). These wins indicate AMD's strengths in memory-intensive or instruction-heavy operations, but they do not offset Intel's broad lead elsewhere.

Multithread performance shows Intel ahead by 16.6% (11482 versus 9849), and Integer Math favors Intel by 26.6% (37644 versus 29737). The overall average benchmark scores reflect this: Intel's average is 15022, while AMD's is 14503. Both processors sit at the 69th percentile among all CPUs in the database, but Intel's raw scores are consistently higher in most categories.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i3-1315U is built on Raptor Lake architecture, specifically the Raptor Lake-U variant, using Intel's 10 nm process node. It has 6 cores and 8 threads, with a base clock of 1200 MHz and a boost clock of 4.50 GHz. Its thermal design power is 15 watts, reflecting its mobile market segment. The chip uses the Intel BGA 1744 socket and supports both DDR4 and DDR5 memory. Integrated graphics are UHD Graphics 64EU.

The AMD Ryzen 3 4300G belongs to the 4000 series, based on Zen 2 architecture with the Renoir codename. It is manufactured on TSMC's 7 nm process, a smaller node than Intel's 10 nm. The chip packs 9,800 million transistors on a 156 mm² die. It has 4 cores and 8 threads, with a base clock of 3.80 GHz and a boost clock of 4.00 GHz. Its TDP is 65 watts, substantially higher than Intel's 15 watts, reflecting its desktop orientation. The socket is AMD Socket AM4, and memory support is limited to DDR4 with a recorded bandwidth of 51.2 GB/s. Integrated graphics are Radeon Vega 6.

Cache hierarchies differ significantly. Intel provides 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache. AMD offers 64 KB L1 per core, 512 KB L2 per core, and only 4 MB of shared L3. Intel's larger L3 cache likely contributes to its strong single-threaded and floating-point performance. AMD's smaller cache sizes are offset by higher base clocks and a more efficient process node.

Connectivity also differs. Intel uses PCIe Gen 4 with 8 lanes (CPU only), while AMD uses PCIe Gen 3 with 16 lanes. Intel's newer PCIe standard offers higher bandwidth per lane, though AMD provides more total lanes. Neither chip supports ECC memory. The Intel part has a locked multiplier, while the AMD chip has an unlocked multiplier, allowing overclocking on compatible boards. Release dates are far apart: Intel launched on January 3, 2023, while AMD launched on July 20, 2020.

FAQ

Q: Which processor has better single-core performance?

A: The Intel Core i3-1315U wins decisively. In Cinebench R23 single-core, Intel scores 1323 against AMD's 1184, an 11.7% lead. PassMark single-thread shows an even larger gap: 3380 versus 2425, a 39.4% advantage.

Q: How do they compare in multi-core workloads?

A: Intel leads across the board. Cinebench R23 multicore shows 9374 versus 8387 (11.8% ahead), and PassMark multithread shows 11482 versus 9849 (16.6% ahead). Intel's higher core count (6 versus 4) contributes to this gap.

Q: Where does AMD actually win?

A: AMD wins four tests: data compression by 8.2%, data encryption by 7.3%, extended instructions by 19%, and random string sorting by 3.3%. These are memory-intensive or SIMD-heavy operations where AMD's higher base clock and memory bandwidth (51.2 GB/s) help.

Q: What is the TDP difference?

A: Intel is rated at 15 watts, while AMD is rated at 65 watts. This reflects their different market segments: Intel is a mobile processor, AMD is a desktop processor. The 50-watt difference has implications for cooling and power delivery requirements.

Q: Do they support the same memory types?

A: No. Intel supports both DDR4 and DDR5, while AMD supports only DDR4. Intel also has a newer PCIe implementation (Gen 4 with 8 lanes) versus AMD's PCIe Gen 3 with 16 lanes.

Q: Which processor has more cache?

A: Intel has more L3 cache (10 MB shared versus 4 MB shared) and more L2 per core (1.25 MB versus 512 KB). AMD has slightly less L1 per core (64 KB versus 80 KB). Intel's larger cache hierarchy aligns with its single-threaded dominance.

The Verdict

The data clearly favors the Intel Core i3-1315U in overall performance. It wins 13 of 17 head-to-head benchmarks, including every Cinebench test and the majority of PassMark workloads. Its average benchmark score of 15022 exceeds AMD's 14503 by roughly 3.6%. The Intel part is particularly strong in single-threaded tasks, floating-point math, and physics simulations, where its advantages range from 26.6% to 105%.

However, the AMD Ryzen 3 4300G is not without merit. It wins in data compression, encryption, extended instructions, and string sorting, with its best result being a 19% lead in extended instructions. For users running those specific workloads, AMD offers measurable advantages. Its higher base clock (3.80 GHz versus 1.20 GHz) and larger memory bandwidth (51.2 GB/s) support these wins.

The market segments differ fundamentally. Intel is a 15-watt mobile chip from 2023, while AMD is a 65-watt desktop chip from 2020. The Intel part's newer architecture and larger cache provide better efficiency and raw performance per watt. The AMD part's unlocked multiplier offers overclocking potential, but the base performance gap is substantial. For most users, the data supports choosing Intel, unless the specific AMD-favorable workloads dominate their usage.

Where Each One Wins

The Intel Core i3-1315U is the clear choice for general computing, productivity, and single-threaded applications. Its PassMark single-thread score of 3380 versus 2425 represents a 39.4% advantage, making it superior for web browsing, office work, and legacy software that relies on single-core performance. Floating-point math (27012 versus 17577, a 53.7% lead) and integer math (37644 versus 29737, a 26.6% lead) make it better suited for engineering tools, financial modeling, and data analysis. Physics simulation (706 versus 454, a 55.5% lead) and prime number finding (41 versus 20, a 105% lead) show strength in scientific and computational workloads. Its 10 MB of shared L3 cache and 6 cores provide a solid foundation for moderate multi-threaded tasks, as confirmed by its 11.8% Cinebench R23 multicore lead.

The AMD Ryzen 3 4300G wins in specialized data-handling scenarios. Data compression (137681 versus 126436) and data encryption (8176 versus 7583) indicate an edge for archive management, backup utilities, and secure communications. Extended instructions (9148 versus 7413, a 19% lead) point to advantages in AVX-heavy code or cryptographic functions. Random string sorting (14503 versus 14028) suggests competent performance for database operations or text processing. Its 51.2 GB/s memory bandwidth and 65-watt power envelope allow sustained throughput in these tasks, despite its smaller 4 MB L3 cache. Users who prioritize these specific operations may find AMD's wins meaningful, but for a balanced workload, the Intel part's broader dominance is conclusive.
