AMD Ryzen 3 8300G vs Intel Core i3-14100 Comparison

Head-to-Head Benchmarks

The head-to-head data reveals a clear pattern: the Intel Core i3-14100 dominates the AMD Ryzen 3 8300G in most compute-heavy workloads, while the AMD chip carves out a smaller but meaningful set of wins in specific tasks. Out of 17 benchmark comparisons, the Intel processor wins 12, with the AMD taking 5.

The most dramatic difference appears in floating-point math, where the Intel Core i3-14100 scores 35,266 against the Ryzen 3 8300G's 25,336, a 39.2% advantage. This is the largest delta in the entire comparison. Physics simulation also shows a wide gap: Intel scores 958 versus AMD's 755, a 26.9% lead. Prime number finding favors Intel by 17% (55 versus 47), and integer math goes Intel's way by 11.8% (45,329 versus 40,534).

In Cinebench tests, the Intel chip leads consistently across all versions. In R15 multicore, Intel scores 1,292 versus 1,231 (5% higher), and in single-core R15, Intel leads 182 versus 173 (5.2%). The R20 multicore result is 5,384 versus 5,131 (4.9% higher), and R20 single-core is 759 versus 724 (4.8%). R23 multicore shows 12,820 versus 12,217 (4.9%), while R23 single-core is 1,809 versus 1,724 (4.9%). These are modest but consistent margins across all rendering workloads.

Data compression strongly favors Intel, with a score of 174,115 versus 158,952, a 9.5% advantage. Multithreaded performance also leans Intel, at 15,095 versus 14,018 (7.7% higher). The pattern suggests that the Intel architecture handles sustained parallel workloads with greater efficiency in most cases.

The AMD Ryzen 3 8300G wins in four distinct areas. Data encryption shows AMD ahead at 9,115 versus 8,838, a 3% edge. Extended instructions go AMD's way at 12,354 versus 11,865, a 4% advantage. Random string sorting is AMD's strongest win at 19,013 versus 17,397, an 8.5% lead. Single-thread performance is nearly tied, with AMD scoring 3,778 versus Intel's 3,759, a razor-thin 0.5% margin. This last result is notable given that the Intel chip has a higher listed base clock.

The average benchmark scores place both CPUs in the same percentile tier. The Intel Core i3-14100 has an average benchmark score of 18,318, while the AMD Ryzen 3 8300G sits at 18,169. Both rank in the 72nd percentile against all CPUs in the database. The nearest rivals for Intel include the Intel Core 3 305 (18,302, 0.1% difference) and Intel Core i3-13100 (18,380, -0.3% difference). For AMD, the nearest rivals are the AMD Ryzen 7 5700U (18,176, 0% difference) and Intel Core i7-9700 (18,180, -0.1% difference). These close deltas indicate that both processors sit in a highly competitive performance band.

The Verdict

The data points to a straightforward conclusion: for pure CPU compute performance, the Intel Core i3-14100 is the stronger choice in the majority of workloads. Its wins span rendering, math, physics, compression, and multithreaded tasks, often by double-digit percentages. The 39.2% lead in floating-point math and 26.9% lead in physics are particularly decisive for anyone running simulations, scientific computing, or 3D rendering.

The AMD Ryzen 3 8300G makes its case in encryption, extended instruction throughput, and string sorting, where it leads by 3% to 8.5%. Its single-thread score is also marginally higher, but the 0.5% difference is within noise. For users whose workloads involve cryptography, string manipulation, or applications that leverage extended instruction sets, the AMD chip holds a small but real advantage.

Both processors share the same core and thread counts, and both rank in the 72nd percentile of all CPUs. The average benchmark scores differ by only 149 points (0.8%), which is negligible in daily use. However, the distribution of wins matters: Intel wins the heavyweight workloads, while AMD wins the lighter, specialized tasks. The data suggests that a user prioritizing broad compute capability should choose the Intel Core i3-14100, while a user with specific encryption-heavy or string-sorting workloads might prefer the AMD Ryzen 3 8300G.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i3-14100 uses the Raptor Lake architecture on a 10 nm process node fabricated by Intel itself. The die size is 163 mm². The AMD Ryzen 3 8300G uses the Zen 4 architecture on a 4 nm process node from TSMC, with a smaller die at 137 mm² and 20,900 million transistors. This process advantage allows AMD to pack more transistors into a smaller area, though the benchmark results show that Intel's larger, older-node design still holds a performance edge in most tests.

Cache configurations differ notably. Intel provides 80 KB of L1 cache per core and 1.25 MB of L2 per core, with 12 MB of shared L3 cache. AMD provides 64 KB of L1 per core and 1 MB of L2 per core, with 8 MB of shared L3 cache. Intel's larger cache hierarchy may contribute to its leads in data compression and integer math, where data locality matters.

Memory support splits the two. Intel supports both DDR4 and DDR5, while AMD supports DDR5 only. AMD lists a memory bandwidth of 83.2 GB/s, while Intel does not report a specific figure. Both use dual-channel memory buses. ECC memory is supported on both, a rare feature for desktop processors.

PCIe connectivity differs: Intel provides Gen 5 with 16 lanes (CPU only), while AMD provides Gen 4 with 14 lanes. This gives Intel a bandwidth advantage for expansion cards and NVMe drives that support the newer standard.

Integrated graphics also diverge. Intel includes UHD Graphics 730, while AMD includes the Radeon 740M. The benchmark data does not include graphics tests, so no performance comparison can be drawn from the recorded numbers.

The sockets are incompatible: Intel uses LGA 1700, AMD uses AM5. The Intel processor has a 60 W TDP, while the AMD chip has a 65 W TDP, a minor difference. Both are locked (multiplier not unlocked), and both launched on the same date.

The manufacturing process difference is striking: 10 nm versus 4 nm. Yet the Intel chip, on the older node, wins most performance tests. This suggests that architectural efficiency, clock behavior, and cache design can outweigh process node advantages in real workloads.

Where Each One Wins

The Intel Core i3-14100 wins in tasks that stress raw arithmetic, physics, and parallel rendering. Floating-point math is its biggest victory, with a 39.2% lead. Physics simulation follows at 26.9%, and prime number finding at 17%. These workloads benefit from the Intel chip's higher base clock (3.50 GHz) and larger L3 cache (12 MB versus 8 MB). Data compression (9.5% lead) and integer math (11.8% lead) also fall into Intel's column, making it the better option for file archiving, database operations, and general number crunching.

The AMD Ryzen 3 8300G wins in areas that suggest optimization for specific instruction paths. Data encryption (3% lead) and extended instructions (4% lead) point to the Zen 4 architecture's efficiency in cryptographic and specialized operations. Random string sorting shows an 8.5% advantage, which could benefit text processing and data parsing tasks. Its single-thread score is marginally higher (0.5%), but this is negligible. The AMD chip also has a higher boost clock (4.90 GHz versus 4.70 GHz), which may contribute to its wins in latency-sensitive workloads.

For users seeking a balanced desktop processor for gaming, office work, and general computing, the data favors the Intel Core i3-14100 due to its broader set of wins. For users whose workloads are specifically encryption-heavy, involve extended instruction sets, or require fast string sorting, the AMD Ryzen 3 8300G offers targeted advantages. The 5-wins versus 12-wins split makes the choice clear for most scenarios, but the specialized nature of AMD's victories means it should not be dismissed outright.
