# AMD Ryzen 5 8400F + NVIDIA GeForce RTX 3090

This build pairs AMD's 6-core Zen 4 desktop processor with NVIDIA's flagship Ampere GPU, creating a desktop system that sits at the 75th percentile overall among all CPU+GPU combinations in the database. The CPU holds a 77th percentile position among all CPUs, while the GPU ranks at the 73rd percentile among all GPUs, indicating a well-matched pair where neither component dramatically overshadows the other in benchmark standings. The combination targets high-resolution gaming and compute-heavy workloads, though the data available for this exact pairing is aggregated from separate component benchmarks rather than measured system-level FPS results.

CPU Analysis

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor built on the Zen 4 architecture with the Phoenix codename, manufactured on TSMC's 4 nm process node. The die contains 25,000 million transistors across a 178 mm² area, and the chip operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. The processor features a 65W TDP, making it a power-efficient option for desktop builds. Cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache, which is modest by modern standards but sufficient for the core count.

The CPU's benchmark results reveal a processor that scales reasonably well with thread count. The 3DMark scores progress from 951 in single-thread to 1,874 in 2-thread, 3,563 in 4-thread, 5,275 in 8-thread, and 6,091 in 16-thread, with a max-thread score of 6,165. This scaling pattern shows diminishing returns beyond 8 threads, which is typical for a 6-core/12-thread part — the additional logical threads provide some benefit but the physical core count limits gains. Cinebench results reinforce this picture: R15 single-core scores 296 and multi-core 2,101; R20 single-core 1,236 and multi-core 8,757; R23 single-core 2,943 and multi-core 20,851. The R23 multi-core score of 20,851 indicates strong sustained multi-threaded performance for productivity tasks.

PassMark results add depth to the analysis. The multi-thread score is 24,389, while single-thread is 3,685. Integer math scores 74,021, floating-point math 46,217, and extended instructions 22,175. Data compression achieves 288,158, while data encryption scores 16,646. Random string sorting reaches 34,604, and find prime numbers scores 89. These figures suggest the CPU handles integer-heavy workloads particularly well, with more modest floating-point and encryption throughput. The average benchmark score of 25,005 places the 8400F at the 77th percentile, meaning it outperforms roughly three-quarters of all CPUs in the database.

The nearest rival comparisons show how tightly grouped this performance tier is. The AMD Ryzen 5 7500F scores 24,964, just 0.2% lower. The Intel Core i7-11850H scores 24,935, 0.3% lower. The Intel Core i7-13620H scores 24,911, 0.4% lower. The AMD EPYC 9474F scores 25,103, 0.4% higher. These deltas are negligible in real-world terms — the 8400F sits squarely in a performance band where architectural differences and cooling solutions will matter more than raw score variations.

Benchmark Performance

The CPU delivers an average benchmark score of 25,005, placing it at the 77th percentile among all CPUs. The GPU's average benchmark score is 27,565, placing it at the 73rd percentile among all GPUs. The combined system percentile is 75, indicating that this pairing outperforms three-quarters of all recorded CPU+GPU combinations in the database.

Looking at specific GPU benchmarks, the RTX 3090 achieves 5,118 in 3DMark Steel Nomad DX12, which reflects modern DirectX 12 gaming workloads. Geekbench scores include 172,758 in OpenCL and 53,927 in Vulkan, showing strong compute performance across different APIs. PassMark results show 26,645 in G3D, 15,356 in GPU Compute, 1,063 in G2D, and DirectX scores of 268 for DX9, 220 for DX11, 182 for DX10, and 110 for DX12. The DirectX scores are notable — the DX12 score is lower than DX11 and DX9, which may reflect driver optimization or benchmark methodology rather than raw capability, since the 3DMark Steel Nomad result indicates strong DX12 performance.

The GPU's nearest rivals include the NVIDIA GeForce RTX 4070 Mobile at 27,435 (0.5% higher), the AMD Radeon RX 6700 XT at 27,425 (0.5% higher), the AMD Radeon Pro Vega 20 at 27,839 (1% lower), and the AMD Radeon RX 7800M at 27,883 (1.1% lower). The RTX 3090's position between these rivals shows it remains competitive with newer mid-range and mobile parts, though its 73rd percentile ranking indicates it is no longer at the top of the GPU hierarchy.

The combined picture shows a system where the CPU and GPU are closely matched in percentile terms — 77th for the CPU versus 73rd for the GPU. This suggests neither component is dramatically holding back the other in most workloads, though specific applications may favor one over the other. The CPU's higher percentile indicates it has slightly more headroom relative to the broader CPU market than the GPU does relative to the broader GPU market.

GPU Analysis

The NVIDIA GeForce RTX 3090 is built on the Ampere architecture with the GA102 chip, manufactured on Samsung's 8 nm process node. The die contains 28,300 million transistors across a 628 mm² area, with a transistor density of 45.1M per mm². The GPU operates with a base clock of 1395 MHz and a boost clock of 1695 MHz, with memory clocked at 1219 MHz (19.5 Gbps effective). The card is a triple-slot design measuring 336 mm in length, 140 mm in height, and 61 mm in width, requiring a 750W suggested PSU and featuring a single 12-pin power connector.

The memory subsystem is a standout feature: 24 GB of GDDR6X on a 384-bit bus delivers 936.2 GB/s of bandwidth. This is substantial by any measure and positions the card for high-resolution textures, large datasets, and memory-intensive compute workloads. The 384-bit bus width is wider than most contemporary GPUs, which helps sustain high throughput in bandwidth-bound scenarios.

Compute resources include 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. Pixel rate is 189.8 GPixel/s, texture rate is 556.0 GTexel/s, and FP32 performance is 35.58 TFLOPS with FP16 at 35.58 TFLOPS (1:1). The RT cores enable hardware-accelerated ray tracing, while the tensor cores provide AI acceleration for DLSS and other neural network workloads. The 1:1 FP16 to FP32 ratio is notable for compute workloads that can use reduced precision.

Benchmark results show the GPU's strengths and weaknesses. The 3DMark Steel Nomad DX12 score of 5,118 indicates solid modern gaming performance. PassMark G3D of 26,645 and GPU Compute of 15,356 show strong overall graphics and compute capability. The Geekbench scores — 172,758 OpenCL and 53,927 Vulkan — confirm that the card performs well across different compute APIs. The lower DirectX 10/11/12 PassMark scores (182, 220, 110 respectively) are likely artifacts of the benchmark methodology rather than representative of actual DX12 performance, given the strong Steel Nomad result.

The GPU's 73rd percentile ranking and average score of 27,565 place it alongside newer mid-range cards like the RTX 4070 Mobile and RX 6700 XT, both within 0.5%. This indicates that while the RTX 3090 is no longer a top-tier performer relative to the entire GPU market, it remains competitive with modern mid-range offerings, particularly in memory capacity and bandwidth where its 24 GB GDDR6X configuration exceeds most newer cards.

Gaming Performance

No measured FPS rows exist for this exact CPU+GPU combination in the database, so all gaming performance figures presented here are estimates derived from the component benchmark scores rather than direct system measurements. The CPU's 3DMark single-thread score of 951 and the GPU's 3DMark Steel Nomad DX12 score of 5,118 provide the basis for these estimates.

At 1080p resolution, the CPU's single-thread performance is likely adequate to feed the GPU in most titles, though the 6-core/12-thread configuration may limit frame rates in heavily threaded games that benefit from more than 12 threads. The GPU's 73rd percentile ranking suggests it can deliver high frame rates at 1080p, but the system may be CPU-limited in less demanding titles where frame rates exceed 200 FPS.

At 1440p, the balance shifts toward the GPU, which should deliver smooth gameplay in most titles. The 24 GB VRAM and 936.2 GB/s bandwidth provide ample headroom for high-quality textures and effects. Estimated performance suggests this is where the system is best balanced, with neither component consistently bottlenecking the other.

At 4K, the GPU becomes the primary performance driver. The RTX 3090's memory bandwidth and compute throughput should handle 4K gaming well, though the GPU's 73rd percentile ranking means it is not at the absolute top tier for 4K. The CPU's 77th percentile ranking ensures it will rarely be the limiting factor at this resolution, where per-frame CPU work is relatively lower.

Who Should Build It

This system targets users who need strong GPU compute and memory bandwidth without requiring a top-tier CPU. The RTX 3090's 24 GB VRAM and 936.2 GB/s bandwidth make it particularly suited for content creators working with large 3D scenes, high-resolution video, or machine learning models that benefit from substantial GPU memory. The CPU's 6 cores and 12 threads handle typical productivity tasks well, as indicated by its 77th percentile ranking.

Gamers targeting 1440p or 4K resolution will find this system well-matched, as the GPU is the primary driver at these resolutions and its 73rd percentile ranking ensures solid frame rates. The CPU's single-thread performance of 951 in 3DMark is sufficient for most gaming scenarios, though competitive esports players seeking maximum frame rates at 1080p might find the CPU limiting.

Software developers working on multi-threaded applications will benefit from the CPU's PassMark multi-thread score of 24,389, while data scientists and researchers can leverage the GPU's compute scores (172,758 OpenCL) for model training and inference. The system is also a reasonable choice for students in engineering or design programs, though the GPU's 350W TDP makes it less practical for users who prioritize energy efficiency.

Small business workstations requiring GPU acceleration for rendering, simulation, or video production will find this build capable, with the CPU's 65W TDP keeping idle and light-load power consumption manageable while the GPU provides substantial compute throughput when needed.

Build Overview

This is a desktop-class build pairing the AMD Ryzen 5 8400F (6 cores, 12 threads, Zen 4 architecture) with the NVIDIA GeForce RTX 3090 (Ampere architecture, 24 GB GDDR6X). The CPU is an active production part on the AMD Socket AM5 platform, released in 2024, while the GPU is end-of-life, having been released in 2020 as part of the GeForce 30-series.

The system's combined percentile of 75 places it above three-quarters of all recorded CPU+GPU combinations. The CPU's 77th percentile and GPU's 73rd percentile are closely matched, indicating this is a balanced pairing rather than one where a high-end component is bottlenecked by a low-end counterpart. The CPU's average benchmark score of 25,005 and the GPU's 27,565 contribute to a system that should handle most workloads well, from gaming to productivity to compute.

The CPU's 65W TDP is notably low for a desktop processor, which helps keep system power consumption reasonable when the GPU is idle. The GPU's 350W TDP, however, means the system draws significant power under load, and the suggested 750W PSU provides appropriate headroom. This is not a compact or power-efficient build by modern standards — the GPU is a triple-slot card measuring 336 mm in length — but it offers substantial performance for users who need it.

Balance and Bottleneck

The percentile difference between the CPU (77th) and GPU (73rd) is small, suggesting the system is reasonably balanced. However, the nature of bottlenecks varies by workload. In CPU-bound tasks like software compilation or single-threaded productivity, the CPU's 6-core/12-thread configuration will determine performance. The single-thread score of 951 in 3DMark and 2,943 in Cinebench R23 indicate solid but not exceptional single-thread performance.

In GPU-bound workloads like 3D rendering or high-resolution gaming, the RTX 3090 will be the limiting factor. Its 73rd percentile ranking means it trails roughly a quarter of all GPUs in the database, so users seeking maximum frame rates in the latest titles at 4K may find the GPU is the constraint. The GPU's PassMark G3D score of 26,645 and 3DMark Steel Nomad score of 5,118 provide context for its capability.

The FPS scaling evidence, while estimated, suggests that at 1080p the CPU may become the bottleneck in less demanding games where frame rates exceed what the CPU's single-thread performance can sustain. At 1440p and 4K, the GPU becomes the primary limiter, and the system should scale more predictably with game graphics settings. Users who plan to play at 1080p with high refresh rates might consider a stronger CPU, while those targeting 4K will benefit most from the GPU's memory bandwidth and compute throughput.

Upgrade Path and Platform

The AMD Ryzen 5 8400F uses the AMD Socket AM5 platform, which supports DDR5 memory in a dual-channel configuration with 83.2 GB/s bandwidth. The CPU provides 20 PCIe Gen 4 lanes, while the GPU uses PCIe 4.0 x16. The platform supports unlocked multipliers, allowing overclocking of the 65W TDP processor to extract additional performance.

The GPU is end-of-life, with the GeForce 40 series as its successor. The RTX 3090's 350W TDP and suggested 750W PSU mean that a GPU upgrade would require ensuring the PSU has sufficient capacity. The 24 GB VRAM and 936.2 GB/s bandwidth are generous, so users upgrading from this GPU would likely wait for a significant generational improvement rather than a side-grade.

A sensible next upgrade path would be to a higher-core-count CPU on the same AM5 socket, such as a Ryzen 7 or Ryzen 9 part, if multi-threaded workloads become more demanding. The CPU's current multi-thread score of 24,389 in PassMark and 20,851 in Cinebench R23 provide a baseline — users needing substantially more multi-threaded performance would benefit from more cores. The platform's DDR5 memory support means memory upgrades are possible within the same socket generation.

For GPU upgrades, the PCIe 4.0 x16 interface ensures compatibility with newer cards, and the 750W suggested PSU provides headroom for most GPUs below the highest-end tier. The triple-slot GPU form factor means case compatibility is a consideration for future builds, but within the same case, a similar-sized or smaller GPU would fit. The 336 mm length of the current GPU indicates the case has sufficient space for large cards.
