AMD Ryzen 3 PRO 8300G vs Intel Core i5-11400 Comparison

The AMD Ryzen 3 PRO 8300G and Intel Core i5-11400 occupy the same performance percentile, yet their benchmark profiles are dramatically different. The data shows a clear split: Intel’s six-core Rocket Lake part dominates throughput-oriented tests, while AMD’s four-core Zen 4 chip wins decisively in single-threaded workloads. Out of 17 head-to-head benchmarks, the Intel Core i5-11400 takes 15 wins, while the AMD Ryzen 3 PRO 8300G secures only 2—but those two wins are significant.

Head-to-Head Benchmarks

The most striking result is in PassMark’s single-thread test, where the AMD Ryzen 3 PRO 8300G scores 3550 against Intel’s 2990, a 18.7% advantage. This is the largest delta in the entire comparison and reflects the architectural gulf between a modern 4nm Zen 4 design and a 14nm Rocket Lake part. The same pattern appears in the duplicated PassMark singlethread result, reinforcing that AMD’s per-core performance is categorically superior.

Every other benchmark favors Intel, often by wide margins. In Cinebench R23 multicore, the Intel Core i5-11400 posts 14132 versus AMD’s 12359, a 12.5% lead. The margin is consistent across the entire Cinebench suite: R15 multicore (1424 vs 1245, -12.6%), R20 multicore (5935 vs 5190, -12.6%), R15 singlecore (200 vs 175, -12.5%), and R20 singlecore (837 vs 732, -12.5%). Interestingly, Intel’s single-core Cinebench wins are nearly as large as its multicore wins, suggesting that the older architecture’s higher boost clock (4.40 GHz vs 4.90 GHz) does not fully compensate for AMD’s IPC advantage in this particular workload.

The PassMark integer and floating-point math tests show the widest gaps. Intel scores 57601 in integer math versus AMD’s 37292, a 35.3% deficit for the Ryzen chip. Floating-point math follows suit: 34004 versus 23374, a 31.3% gap. These results are consistent with the core-count disparity—Intel has 6 cores and 12 threads versus AMD’s 4 cores and 8 threads—allowing the i5-11400 to apply more parallel execution resources to compute-heavy tasks.

Data compression and encryption also favor Intel decisively. The i5-11400 manages 206952 in PassMark data compression, beating the Ryzen 3 PRO 8300G’s 150567 by 27.2%. Encryption shows a 16.1% lead (10264 vs 8607), and extended instructions reveal a 23.2% gap (14901 vs 11451). The least dramatic Intel wins are in PassMark physics (793 vs 772, only 2.6% ahead) and find prime numbers (49 vs 47, 4.1% ahead), where the AMD chip’s per-core efficiency narrows the gap despite having fewer threads.

The average benchmark scores tell a similar story: AMD’s average is 17278, while Intel’s is 17067, a difference of about 1.2%. However, this aggregate masks the fact that Intel’s wins are often larger in magnitude than AMD’s two single-thread victories. The nearest rivals for each chip reinforce this—AMD’s closest competitor is the Intel Core i5-12450H (0.2% delta), while Intel’s nearest rival is the AMD EPYC 7573X (0% delta), showing that both chips sit in a crowded mid-range field.

Where Each One Wins

The AMD Ryzen 3 PRO 8300G wins exclusively in single-threaded PassMark tests. This makes it the better choice for lightly threaded applications that depend on one or two cores running at maximum efficiency—legacy software, certain scripting workloads, and interactive responsiveness where the 18.7% single-thread advantage translates directly to lower latency. The data also shows that AMD’s per-core performance is strong enough to nearly match Intel in physics simulations (772 vs 793), despite having two fewer cores.

The Intel Core i5-11400 wins everywhere else, making it the superior option for multi-threaded productivity. Content creation, 3D rendering, and data processing workloads that scale with core count will benefit from its 6-core, 12-thread configuration. The 35.3% lead in integer math and 31.3% lead in floating-point math are particularly relevant for scientific computing and financial modeling. Data compression, where Intel leads by 27.2%, matters for database operations and file archiving. The i5-11400 also holds a 19.9% advantage in the PassMark multithread test, confirming broad throughput superiority.

For users running a mix of workloads, the Intel chip offers more consistent performance across the board. AMD’s wins are narrow in scope but impactful for specific use cases. The PassMark physics result, where Intel only leads by 2.6%, suggests that the Ryzen 3 PRO 8300G’s architectural efficiency can partially offset its core deficit in real-time simulation tasks.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 3 PRO 8300G uses the Zen 4 architecture on a 4nm TSMC process, with a die size of 137 mm² and 20,900 million transistors. It features 4 cores and 8 threads, with a base clock of 3.40 GHz and boost clock of 4.90 GHz. The cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 8 MB shared L3. Its memory support is DDR5 with dual-channel operation, providing 83.2 GB/s bandwidth, and it supports ECC memory.

The Intel Core i5-11400 uses the Rocket Lake architecture on Intel’s 14nm process, with a die size of 276 mm². It has 6 cores and 12 threads, with a base clock of 2.60 GHz and boost clock of 4.40 GHz. The cache layout is different: 80 KB L1 per core, 512 KB L2 per core, and 12 MB shared L3. Memory support is DDR4 with dual-channel operation, delivering 51.2 GB/s bandwidth, and it lacks ECC support.

The process node difference is the most consequential. TSMC’s 4nm process gives AMD a density and efficiency advantage, while Intel’s 14nm node requires a much larger die (276 mm² vs 137 mm²) to house fewer transistors. The memory bandwidth gap is also significant—83.2 GB/s versus 51.2 GB/s—which contributes to AMD’s single-thread advantage and helps narrow gaps in memory-sensitive workloads. Both chips use PCIe Gen 4, but Intel offers 20 lanes versus AMD’s 14 lanes. The integrated graphics differ as well: AMD pairs with a Radeon 740M, while Intel uses UHD Graphics 730.

The production statuses diverge sharply. The AMD Ryzen 3 PRO 8300G is listed as Active, released in April 2024. The Intel Core i5-11400 is End-of-life, with a release date of March 2021. This reflects the generational gap: AMD’s chip is three years newer and built for the AM5 socket, while Intel’s uses Socket 1200.
