AMD Ryzen 3 4100 vs AMD Ryzen 3 4300G Comparison

The AMD Ryzen 3 4100 and AMD Ryzen 3 4300G are near-identical twins on paper, sharing the same 4-core/8-thread layout, 3.80 GHz base clock, 4.00 GHz boost clock, 65 W TDP, and Zen 2 Renoir architecture on TSMC's 7 nm process. Both are unlocked, both support DDR4-3200 dual-channel memory, and both sit in the 69th percentile of all CPUs. Yet the benchmark data tells a one-sided story: the Ryzen 3 4100 wins all 17 head-to-head comparisons, with margins ranging from 4.4% to 24%. The 4300G fights back with its integrated Radeon Vega 6 graphics and double the PCIe lanes (16 vs. 8), but in pure CPU workloads, it trails its sibling across every single test.

Where Each One Wins

The Ryzen 3 4100 is the clear winner in every compute-heavy scenario. Its largest advantage appears in PassMark physics, where it scores 563 against the 4300G's 454 — a 24% lead. This suggests a meaningful edge in simulation and gaming physics workloads that rely on tightly threaded CPU calculations. The 4100 also dominates Cinebench across all three versions: R15 multicore (946 vs. 845, +12%), R20 multicore (3945 vs. 3522, +12%), and R23 multicore (9394 vs. 8387, +12%). For content creators rendering 3D scenes or exporting video, the 4100 consistently delivers roughly a tenth more throughput.

The 4100's advantage extends to single-threaded performance, though the gap narrows. Cinebench R23 single-core shows 1326 vs. 1184, a 12% edge, while PassMark single-thread is closer at 2531 vs. 2425, just 4.4% apart. This means the 4100 is also the better pick for lightly threaded applications like spreadsheet work, web browsing, or legacy software that relies on one or two cores. In integer math, the 4100 posts 32307 vs. 29737 (+8.6%), and in floating-point math it reaches 19128 vs. 17577 (+8.8%), reinforcing that it handles both general-purpose and scientific calculations faster.

The 4300G's only unique win is its integrated Radeon Vega 6 GPU — a feature the 4100 lacks entirely. For systems built without a discrete graphics card, the 4300G is the only option here that can output video and handle basic 2D/3D acceleration. It also offers 16 PCIe Gen 3 lanes from the CPU versus the 4100's 8 lanes, which could matter for users planning to install multiple NVMe drives or other expansion cards. However, in every CPU benchmark recorded, the 4300G finishes behind. Its best relative showing is in PassMark single-thread (4.4% behind), while its worst is physics (24% behind). The 4300G is a competent quad-core, but it is not the faster processor.

The Verdict

Choose the AMD Ryzen 3 4100 if you need raw CPU performance and already have a discrete GPU. The data is unambiguous: it wins 17 out of 17 benchmarks, including every Cinebench and PassMark test. Its 12% lead across multi-core rendering and an 8-12% edge in most math workloads makes it the better choice for gaming rigs with a separate graphics card, budget content-creation builds, or any system where the CPU is the bottleneck. The 4100 also has a launch MSRP of $99, which the database records, though its actual street price may vary.

Choose the AMD Ryzen 3 4300G if you are building a system without a dedicated GPU. Its integrated Radeon Vega 6 graphics means the machine can boot, run a desktop, and play lightweight games or accelerate video playback without any add-in card. The 4300G's CPU performance is still respectable — it sits in the 69th percentile — but it trails the 4100 by margins that range from 4.4% to 24%. The extra PCIe lanes (16 vs. 8) also give it more expansion headroom. However, if you ever plan to add a discrete GPU later, the 4100 will deliver better frame rates and faster rendering for the same core count.

Head-to-Head Benchmarks

The biggest single win for the Ryzen 3 4100 is in PassMark physics, where it scores 563 against the 4300G's 454. That 24% delta is the largest of any comparison and suggests the 4100's memory subsystem or scheduler handles rigid-body or particle simulations more efficiently. The next-largest margin is in PassMark find prime numbers, where the 4100 hits 23 versus 20, a 15% lead — a test that stresses integer loops and branch prediction.

Cinebench results are remarkably consistent. The 4100 wins R15 multicore by 12% (946 vs. 845), R20 multicore by 12% (3945 vs. 3522), and R23 multicore by 12% (9394 vs. 8387). Single-core Cinebench shows similar margins: R15 at 11.8% (133 vs. 119), R20 at 11.9% (556 vs. 497), and R23 at 12% (1326 vs. 1184). This uniformity suggests the 4100's advantage is architectural rather than workload-specific — it is simply executing the same instructions faster per clock.

PassMark's multi-threaded suite follows the same pattern. The 4100 leads in data compression by 8.7% (149609 vs. 137681), data encryption by 11.7% (9133 vs. 8176), extended instructions by 8.5% (9923 vs. 9148), floating-point math by 8.8% (19128 vs. 17577), integer math by 8.6% (32307 vs. 29737), and multithread overall by 12.2% (11050 vs. 9849). Random string sorting is 8.7% faster (15760 vs. 14503). The narrowest gap is PassMark single-thread, where the 4100 leads by just 4.4% (2531 vs. 2425) — a sign that both chips are close in basic IPC, but the 4100 pulls ahead under sustained load.

FAQ

Q: Which CPU has the higher average benchmark score?

A: The Ryzen 3 4100 averages 14505, while the 4300G averages 14503. The difference is 0.02%, effectively a tie, and both sit at the 69th percentile of all CPUs.

Q: Do both processors have the same core and thread counts?

A: Yes. Both the Ryzen 3 4100 and Ryzen 3 4300G have 4 cores and 8 threads, with a 3.80 GHz base clock and a 4.00 GHz boost clock.

Q: What is the L3 cache difference between the two?

A: The 4100 has 8 MB of shared L3 cache, while the 4300G has 4 MB of shared L3 cache. This doubling of L3 is likely a key reason the 4100 performs better in most benchmarks.

Q: Does the Ryzen 3 4300G have integrated graphics?

A: Yes, the 4300G includes Radeon Vega 6 integrated graphics. The 4100 has no integrated graphics, requiring a discrete GPU for video output.

Q: How much faster is the 4100 in Cinebench R23 multi-core?

A: The 4100 scores 9394, which is 12% higher than the 4300G's 8387. This is consistent with the 12% margins seen in Cinebench R15 and R20 multi-core.

Q: Which chip has more PCIe lanes?

A: The 4300G offers 16 PCIe Gen 3 lanes from the CPU, while the 4100 provides only 8 lanes. This matters for expansion cards and NVMe storage.

Architecture Differences

Both chips are built on the same Zen 2 Renoir architecture, using TSMC's 7 nm process with 9,800 million transistors on a 156 mm² die. They share identical core counts, clock speeds, TDP, memory support (DDR4, dual-channel, 51.2 GB/s), and lack ECC memory support. Both are socket AM4, both are unlocked for overclocking, and both belong to AMD's 4000 series.

The critical architectural split is cache. The Ryzen 3 4100 packs 8 MB of shared L3 cache, while the 4300G is limited to 4 MB. Both use 64 KB L1 and 512 KB L2 per core. This L3 deficit is the most probable driver of the 4100's consistent 8-12% performance lead, as more shared cache reduces memory latency for heavily threaded workloads. The 4100 also has fewer PCIe lanes (8 vs. 16), which suggests it was positioned for simpler builds, while the 4300G's extra lanes support its integrated graphics and additional expansion.

The presence of Radeon Vega 6 in the 4300G is the other major difference. The 4100 has no iGPU, meaning it requires a discrete graphics card. Additionally, the 4100 launched in April 2022 with a $99 MSRP and part number 100-000000510100-100000510BOX, while the 4300G launched earlier in July 2020 with part number 100-000000144 and no recorded MSRP. Both parts remain in active production, and both support DDR4 memory exclusively, with no 3D V-Cache option on either.
