AMD Ryzen 5 3400G

The AMD Ryzen 5 3400G is a 4-core, 8-thread desktop processor built on the Zen+ architecture, launched in July 2019 with a launch MSRP of $149. It combines a 65W TDP with integrated Radeon RX Vega 11 graphics, placing it in the 47th percentile of all CPUs in the benchmark database. This is a part that prioritizes balanced everyday performance with a strong integrated GPU, rather than raw multi-core muscle.

Benchmark Performance

The Ryzen 5 3400G’s average benchmark score is 2055, which places it in a tightly contested cluster of rivals. The data shows it is essentially neck-and-neck with the Intel Xeon E-2124G, trailing by just 0.2% (2052 vs. 2055). Against the Intel Core i5-1145GRE, the 3400G is ahead by 0.2% (2058 vs. 2055), and it leads the Intel Core i7-8705G by 0.3% (2061 vs. 2055). The most favorable comparison is against the Intel Core i7-5775R, where the 3400G posts a 0.3% advantage (2049 vs. 2055). These deltas are within a rounding error, meaning real-world differences among these four parts are negligible in aggregate workloads.

Looking at specific multi-threaded tests, the 3400G delivers Cinebench R23 multi-core score of 7835, which is a solid result for a 4-core part. In Cinebench R20, it scores 3290 multi-core, while in the older R15 test it hits 789. The Geekbench multi-core result is 3634. These numbers indicate a chip that can handle moderate parallel workloads but will not compete with higher-core-count processors. The 3DMark results show scaling from 1703 at 4 threads to 2391 at 8 threads, with a maximum-thread score of 2384 — meaning the chip is effectively saturated at 8 threads, which aligns with its 4-core/8-thread design.

The 47th percentile ranking confirms this is a mid-pack performer. It is not a top-tier compute engine, but it is far from a slouch. The benchmark data positions it as a capable entry-level to mid-range processor for everyday tasks and light productivity, with its integrated graphics being the primary differentiator rather than raw CPU throughput.

Platform and Compatibility

The Ryzen 5 3400G uses the AMD Socket AM4, which is one of the longest-lived desktop sockets in the modern era. It supports dual-channel DDR4 memory with a memory bandwidth of 46.9 GB/s. The processor provides PCIe Gen 3 connectivity, which is standard for its generation. ECC memory is not supported, so this is not aimed at workstation or server builds requiring error-correcting memory.

The chip is built on GlobalFoundries’ 12 nm process node, with 4,940 million transistors on a 210 mm² die. Cache configuration includes 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The multiplier is unlocked, allowing overclocking on compatible AM4 motherboards. The integrated Radeon RX Vega 11 graphics means this processor can function without a discrete GPU, which is a significant compatibility consideration for small-form-factor or budget-oriented builds.

The production status is listed as Active, meaning the part is still in the market. The AM4 platform offers a clear upgrade path to newer Ryzen processors within the same socket family, though the 3400G is a Picasso (Zen+) part, so compatibility with newer 5000-series chips depends on motherboard BIOS support. The 65W TDP makes it easy to cool with standard air coolers, and its power requirements are modest.

Who Should Consider It

The benchmark data points to specific use cases for the Ryzen 5 3400G. For office productivity and general desktop use — web browsing, document editing, spreadsheets, and light multitasking — the 4-core/8-thread configuration with a single-thread score of 1106 in Cinebench R23 and 1137 in Geekbench is more than adequate. The 3DMark 2-thread score of 994 shows decent responsiveness for lighter workloads.

For gaming, the integrated Radeon RX Vega 11 makes this a compelling choice for entry-level 1080p gaming without a discrete GPU. The CPU portion, with a Cinebench R23 multi-core score of 7835, will not bottleneck older or less demanding titles, though modern AAA games that favor higher core counts will see limitations. The 8-thread 3DMark score of 2391 is respectable for a chip in this class.

For content creation, the 3400G is a mixed bag. Light photo editing and casual video rendering are within reach, as indicated by the Cinebench R20 multi-core score of 3290. However, heavy 3D rendering or 4K video editing will strain the 4-core design. Users with such workloads should look at higher-core-count alternatives. The chip is best suited for builders who want a single component that handles both CPU and GPU duties for a basic multimedia PC, a home theater PC, or a secondary machine.

How It Compares

Intel Xeon E-2124G: The 3400G trails this Xeon by a mere 0.2% in average benchmark score (2052 vs. 2055). Both are 4-core parts, but the Xeon does not have integrated graphics as capable, and the 3400G’s Vega 11 GPU gives it a functional advantage for GPU-light builds. In raw CPU terms, they are effectively identical.

Intel Core i5-1145GRE: The 3400G leads this Intel part by 0.2% (2058 vs. 2055). The i5-1145GRE is a low-power mobile-oriented chip, so the 3400G’s slight edge in average score comes with a higher TDP (65W vs. the i5’s lower profile). For desktop use, the 3400G is more practical.

Intel Core i7-8705G: The 3400G is ahead by 0.3% (2061 vs. 2055). The i7-8705G is a higher-tier part with 4 cores, but the 3400G’s newer architecture (Zen+) and better memory support offset that. The i7 has a more powerful integrated GPU, but in CPU-only benchmarks, the 3400G holds its own.

Intel Core i7-5775R: The 3400G leads by 0.3% (2049 vs. 2055). This is an older Broadwell-era part, and the data shows the 3400G has a slight performance edge while also offering a newer platform with better memory bandwidth (46.9 GB/s) and a more modern feature set.

Single-Thread vs Multi-Thread Behavior

The Ryzen 5 3400G exhibits a clear split between its single-thread and multi-thread capabilities. In Cinebench R23, the single-core score is 1106, while the multi-core score is 7835 — a ratio of roughly 7:1, which is expected for a 4-core/8-thread part. The 3DMark results reinforce this: the 2-thread score is 994, which scales to 2391 at 8 threads, showing near-linear scaling up to the thread limit.

This behavior means the 3400G is well-suited for workloads that rely on a few fast threads, such as older games, spreadsheet calculations, and general desktop responsiveness. The single-thread Geekbench score of 1137 indicates solid per-core performance for its generation. In multi-threaded tasks, the chip reaches a plateau at 8 threads, as the max-thread 3DMark score of 2384 is nearly identical to the 8-thread score of 2391 — adding more threads does not help.

For real-world usage, this means the 3400G will feel snappy in everyday tasks, but it will struggle with heavily threaded applications like video encoding or 3D rendering. The 47th percentile ranking reflects this: it is a competent generalist, but not a specialist. Builders should pair it with workloads that respect its 4-core limit, and take advantage of its integrated graphics to keep total system cost low.
