# AMD Ryzen 3 5400U + NVIDIA GeForce RTX 4070 Mobile — Benchmark Database Analysis

The AMD Ryzen 3 5400U paired with the NVIDIA GeForce RTX 4070 Mobile is a laptop-class combination that pairs a 15-watt, 4-core Zen 3 processor with a high-end Ada Lovelace mobile GPU. No measured FPS data exists for this exact combination in the FACT PACK, so all gaming frame rate figures presented here are estimates derived from the individual CPU and GPU benchmark scores, not direct measurements. The combined percentile of this pairing sits at 62, placing it above the median for all CPU+GPU combinations, with the GPU contributing the bulk of the performance weight.

Gaming Performance — measured FPS by game and resolution from measuredFpsUltraByGame (or, if dataIsMeasured is false, frame expectations qualitatively from the benchmark scores and say the figures are estimates)

The FACT PACK contains no measured FPS rows for this CPU+GPU combination, meaning there are no verified frame rates at any resolution for any specific game titles. All gaming performance figures discussed here are estimates based on the raw benchmark scores of both components. The GPU’s PassMark G3D score of 19587 and Geekbench Vulkan score of 108367 indicate strong raw graphics throughput, while the CPU’s Cinebench R23 single-core score of 1320 and multi-core score of 9350 suggest moderate processor capability.

At 1080p resolution with ultra settings, the estimated frame rates would likely be constrained primarily by the CPU in many titles. The Ryzen 3 5400U’s 4 cores and 8 threads, with a boost clock of 4.00 GHz, provide enough single-thread performance for acceptable frame pacing, but the limited core count could bottleneck the RTX 4070 Mobile in CPU-intensive scenes. The GPU is estimated to deliver well above 60 FPS in most esports and older titles, while demanding AAA games might see frame rates in the 50-80 FPS range depending on the title’s CPU utilization.

At 1440p resolution, the GPU becomes the primary limiting factor more often, and the RTX 4070 Mobile’s 8 GB GDDR6 memory with 256.0 GB/s bandwidth is sufficient for most games at this resolution. The estimated frame rates would likely remain playable, though the CPU bottleneck could still appear in games with heavy physics or AI calculations. The 128-bit memory bus width, while smaller than desktop equivalents, still provides adequate bandwidth for the GPU’s 15.62 TFLOPS FP32 compute capability.

At 4K resolution, the RTX 4070 Mobile is estimated to struggle to maintain 60 FPS in most AAA titles at ultra settings, given its mobile-class power envelope of 115 W TDP. The GPU’s 48 ROPs and 144 TMUs suggest it can handle texture-heavy workloads, but the 8 GB VRAM might become a limitation in the most demanding 4K textures. The CPU bottleneck would be less pronounced at this resolution, as the GPU becomes the clear performance ceiling.

Usage Scenarios — grounded in the scores: high-refresh gaming, streaming, video editing, 3D rendering, software development, student and office work

High-refresh gaming: The RTX 4070 Mobile’s PassMark G3D score of 19587 positions it to handle 1080p high-refresh gaming, with estimated frame rates exceeding 144 FPS in less demanding titles. However, the Ryzen 3 5400U’s single-core score of 1320 in Cinebench R23 could limit frame rates in CPU-bound scenarios, potentially preventing the system from consistently hitting 144 FPS in competitive shooters where CPU performance dictates maximum frame rates.

Streaming: The GPU’s Ada Lovelace architecture with 144 tensor cores provides dedicated hardware for encoding tasks, which is beneficial for streaming workloads. The CPU’s 4-core, 8-thread configuration with a multi-core score of 3927 in Cinebench R20 might struggle to handle simultaneous gaming and encoding software if the GPU encoder is not utilized, but the tensor core presence suggests the GPU can offload encoding duties effectively.

Video editing: The RTX 4070 Mobile’s Geekbench OpenCL score of 109197 indicates strong compute acceleration for GPU-accelerated effects and rendering in video editing software. The CPU’s Geekbench multi-core score of 4473 is modest, suggesting that timeline scrubbing and export tasks that rely heavily on CPU processing could be slower, but GPU-accelerated workflows would benefit significantly from the graphics card’s compute power.

3D rendering: The GPU’s 36 RT cores and 144 tensor cores provide hardware-accelerated ray tracing and AI denoising capabilities, which are critical for modern 3D rendering workloads. The PassMark GPU Compute score of 8399 indicates solid general-purpose compute performance, though the CPU’s 4-core limitation could slow scene preparation and physics simulations that run on the processor rather than the GPU.

Software development: The Ryzen 3 5400U’s 8 MB shared L3 cache and 8 threads provide adequate performance for code compilation and development tasks, with the single-core score of 554 in Cinebench R20 suggesting responsive IDE usage. The GPU is largely irrelevant for most development workloads, but the system’s overall balance means developers working on graphics or compute-heavy applications would benefit from the RTX 4070 Mobile’s capabilities.

Student and office work: The CPU’s 15 W TDP and Zen 3 architecture make it efficient for battery-conscious workloads, with the integrated Radeon Vega 6 GPU available for basic display tasks when the discrete GPU is not needed. The Geekbench single-core score of 1419 is sufficient for productivity applications, while the multi-core score of 4473 handles multitasking well within the 4-core constraint.

CPU Analysis — cores, clocks, architecture, what the benchmark scores mean for real workloads

The AMD Ryzen 3 5400U is a 4-core, 8-thread processor based on the Zen 3 architecture, codenamed Cezanne-U, manufactured on TSMC’s 7 nm process node. It operates with a base clock of 2.60 GHz and a boost clock of 4.00 GHz, with a 15 W TDP that makes it suitable for thin-and-light laptops. The processor contains 10,700 million transistors on a 180 mm² die, with 64 KB L1 cache per core, 512 KB L2 cache per core, and 8 MB shared L3 cache.

The benchmark scores reveal a processor that performs near the median for all CPUs, with a percentile of 50. The Cinebench R23 multi-core score of 9350 is respectable for a 4-core part, demonstrating the efficiency of Zen 3 architecture. The single-core score of 1320 indicates competitive per-thread performance, which translates to responsive everyday computing and solid performance in lightly-threaded applications. The Geekbench multi-core score of 4473 and single-core score of 1419 corroborate this picture, showing balanced performance across different benchmark methodologies.

The avgBenchmarkScore of 2765 places this CPU within 0.3% of its nearest rivals, including the AMD Ryzen 3 PRO 4350GE (deltaPct -0.1) and the AMD Ryzen 3 4300GE (deltaPct 0.2). This clustering suggests that the Ryzen 3 5400U delivers performance essentially identical to comparable 4-core parts, with differences that are negligible in real-world usage. The 7 nm process node and TSMC foundry contribute to the efficiency, while the 51.2 GB/s memory bandwidth over dual-channel DDR4 provides adequate data throughput for the processor’s capabilities.

The CPU’s memory support is limited to DDR4 with dual-channel configuration, and it lacks ECC support. PCIe connectivity is Gen 3 with 8 lanes from the CPU, which is sufficient for the RTX 4070 Mobile’s PCIe 4.0 x8 interface, albeit with a generation gap that could theoretically reduce bandwidth. The integrated Radeon Vega 6 GPU provides a fallback display output, but the discrete GPU is the primary graphics solution.

Balance and Bottleneck — which component limits which workload, using percentiles and FPS scaling as evidence

The balance between the Ryzen 3 5400U and RTX 4070 Mobile is heavily skewed toward the GPU. The GPU’s percentile of 73 versus the CPU’s percentile of 50 creates a situation where the processor is the limiting factor in most workloads that require both components. The combined percentile of 62 reflects this imbalance, sitting between the two individual percentiles.

In gaming workloads, the CPU bottleneck manifests at lower resolutions where the GPU can render frames faster than the CPU can feed it draw calls and physics calculations. The CPU’s Cinebench R23 single-core score of 1320 suggests that at 1080p, the processor might limit frame rates to approximately 60-100 FPS in CPU-heavy titles, while the GPU could theoretically render at much higher rates. At 1440p and 4K, the GPU becomes the limiting factor, as its rendering workload increases faster than the CPU’s per-frame responsibilities.

The GPU’s estimated performance at 1080p exceeds what the CPU can support, meaning that in many games, the system would behave as if it had a less powerful GPU than the RTX 4070 Mobile. The PassMark G3D score of 19587 places the GPU near the Radeon RX 6700 XT (deltaPct 0) and GeForce RTX 3090 (deltaPct -0.5), both of which are desktop-class GPUs that would be severely underutilized by a 4-core mobile processor in CPU-bound scenarios.

For compute workloads like 3D rendering, the balance is more favorable to the GPU, as rendering tasks scale well with parallel processing and the RTX 4070 Mobile’s 4608 shading units can be fully utilized. The CPU’s 8 threads can prepare scenes and manage the render pipeline, but the actual rendering computation runs on the GPU. In mixed workloads like video editing, the CPU’s modest multi-core performance (Cinebench R23 multi-core 9350) could create bottlenecks during encoding, while the GPU accelerates effects and previews.

GPU Analysis — VRAM, bandwidth, clocks, RT/tensor hardware, what the benchmark scores mean for rendering

The NVIDIA GeForce RTX 4070 Mobile is built on the Ada Lovelace architecture with the AD106 chip, manufactured on TSMC’s 5 nm process node. It contains 22,900 million transistors on a 188 mm² die, with a transistor density of 121.8M per mm². The GPU operates at a base clock of 1395 MHz and a boost clock of 1695 MHz, with memory running at 2000 MHz (16 Gbps effective). The 8 GB GDDR6 memory is connected via a 128-bit bus, providing 256.0 GB/s of bandwidth.

The GPU’s 4608 shading units, 144 TMUs, and 48 ROPs deliver a pixel rate of 81.36 GPixel/s and a texture rate of 244.1 GTexel/s. The FP32 performance of 15.62 TFLOPS with 1:1 FP16 ratio indicates strong general-purpose compute capability. The 36 RT cores provide hardware-accelerated ray tracing, while 144 tensor cores enable DLSS and AI-based features. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The benchmark scores confirm the GPU’s high-end positioning within mobile parts. The PassMark G3D score of 19587 places it at the 73rd percentile among all GPUs, with nearest rivals including the desktop Radeon RX 6700 XT (deltaPct 0) and GeForce RTX 3090 (deltaPct -0.5). The Geekbench OpenCL score of 109197 and Vulkan score of 108367 demonstrate strong cross-API performance, while the PassMark GPU Compute score of 8399 indicates solid compute capability.

For rendering workloads, the RT cores accelerate ray-traced rendering in compatible applications, and the tensor cores enable AI-accelerated denoising and upscaling. The 8 GB VRAM is adequate for most 1080p and 1440p rendering tasks, though scenes with extremely high-resolution textures might exceed this capacity. The 256.0 GB/s bandwidth is modest compared to desktop counterparts but sufficient for the GPU’s compute throughput.

Who Should Build It — target users and industries (gamers at specific resolutions, content creators, developers, students, small business workstations) tied strictly to the measured performance

Gamers at 1440p resolution represent a primary target for this combination, as the GPU’s performance percentile of 73 suggests it can handle modern titles at this resolution, while the CPU’s 50th percentile might not significantly limit at this higher resolution. Players who prioritize visual fidelity over maximum frame rates would benefit from the RTX 4070 Mobile’s ray tracing capabilities and DLSS support through its tensor cores.

Content creators working with GPU-accelerated software would find this combination suitable, given the GPU’s Geekbench OpenCL score of 109197 and PassMark GPU Compute score of 8399. Video editors using hardware encoding, 3D artists leveraging RT cores, and motion graphics designers using GPU effects would see strong performance in their specific workflows, though CPU-bound tasks like timeline scrubbing in codecs that lack GPU acceleration might be slower.

Software developers working on graphics, game development, or machine learning applications would benefit from the GPU’s tensor cores for AI workloads and CUDA acceleration. The CPU’s 8 threads and 8 MB cache provide adequate compilation performance, and the system’s portability (laptop class) makes it suitable for developers who work across multiple locations.

Students in engineering, computer science, or digital media programs would find the combination capable for their coursework, from programming assignments to 3D modeling projects. The 15 W CPU TDP contributes to battery life for campus portability, while the GPU handles graphics-intensive projects.

Small business workstations requiring GPU acceleration for tasks like CAD, architectural visualization, or video production would benefit from this combination, provided the software scales well with the GPU’s compute capabilities. The system’s laptop form factor allows for flexible deployment, though the GPU’s 115 W TDP suggests it requires adequate cooling and power delivery.

Build Overview

This is a laptop-class build (buildClass: "laptop") combining the AMD Ryzen 3 5400U mobile processor with the NVIDIA GeForce RTX 4070 Mobile GPU. The CPU is a 4-core, 8-thread Zen 3 part designed for power efficiency with a 15 W TDP, while the GPU is a high-end Ada Lovelace mobile graphics solution with a 115 W TDP. The combined percentile of 62 places this system above the median for all CPU+GPU combinations, with the GPU providing the majority of the performance weight.

The pairing represents an unusual combination of a low-power, budget-oriented CPU with a high-performance GPU. The processor’s 50th percentile positioning indicates mid-tier performance, while the GPU’s 73rd percentile marks it as a high-end part. This creates a system that excels in GPU-bound workloads but may feel underpowered in CPU-intensive tasks. The laptop form factor means both components are integrated into a portable chassis, with the GPU’s IGP slot width and portable-device-dependent display outputs reflecting the mobile design.

Upgrade Path and Platform

The CPU uses AMD Socket FP6, which is specific to mobile platforms and not upgradeable in the traditional sense. The memory support is DDR4 with dual-channel configuration, providing 51.2 GB/s of bandwidth. The CPU’s PCIe connectivity is Gen 3 with 8 lanes, while the GPU uses PCIe 4.0 x8, meaning the GPU interface runs at Gen 3 speeds due to the CPU’s older PCIe generation.

The GPU has a 115 W TDP and no power connectors, drawing power through the motherboard as is typical for mobile GPUs. The suggested PSU is not specified in the data, reflecting the laptop form factor where power delivery is handled by the system’s power adapter and internal VRM design.

A sensible next upgrade for this platform would be a newer CPU that supports the same socket and memory type, though the mobile socket limits options. The GPU, being integrated into the laptop motherboard, is not upgradeable. Given the CPU’s 4-core limitation, users seeking more balanced performance would need to consider a completely new laptop platform with a more powerful processor paired with the same class of GPU. The GPU’s successor, the GeForce 50 Mobile, represents the next generation, while the CPU’s Ryzen 3 generation is followed by newer AMD mobile processors.
