DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEPairing the AMD Ryzen 5 5600G (60/100 on our gaming index) with the NVIDIA RTX 4070 (43/100) raises one practical question: do they pull together, or does one hold the other back? We ran this exact combination across all supported resolutions to answer it with numbers rather than guesswork.
Quick take: 1440p is the resolution to target
At 1080p the Ryzen 5 5600G becomes the limiting part (~21% CPU bottleneck), whereas at 4K the RTX 4070 is the limiting part (~38% GPU bottleneck). Of the common 16:9 sizes, the highest this pair holds above 60 FPS in AAA titles is 1440p, where it averages 64 FPS — that is the resolution worth buying a monitor for. Across every resolution tested, ultrawides included, the system runs at 70% average efficiency.
Think of resolution as a dial that splits the weight between CPU and GPU. Drop to 1080p and you wring out the RTX 4070 while leaning harder on the Ryzen 5 5600G; push to 4K and the opposite happens. Synergy here swings between 62% and 79% depending on where you sit.
Down to real numbers: In esports titles like Valorant this pair flies — around 438 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~22 FPS at 4K, which is where the RTX 4070's ceiling really shows. Overall, expect about 87 FPS average in AAA games at 1080p and around 42 FPS at 4K.
[CPU] Ryzen 5 5600G
The Ryzen 5 5600G scores 60/100 on this model's gaming scale, with 6 cores and 12 threads. In this pairing its job is to serve frames fast enough to never leave the graphics card waiting.
[GPU] RTX 4070
The RTX 4070 scores 43/100 on this model's gaming scale. Its 12 GB of GDDR6X set how far it can go on resolution and texture quality before video memory runs short. It draws every pixel, so its weight grows the higher you push the resolution.
On the chemistry of the pair: Both parts come from nearby generations, which usually means a natural pairing with no platform surprises. You're combining an AMD platform with an NVIDIA GPU — a perfectly valid mix that imposes no penalty.
DO YOU NEED TO CHANGE ANYTHING?
At 1440p neither part appreciably holds the other back, so there is nothing you need to change. The Ryzen 5 5600G and the RTX 4070 stand as they are; a 550W supply gives the build headroom.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Ryzen 5 5600G (65W) and RTX 4070 (200W) add up to roughly 265W under load. Adding 150W for the rest of the system gives 415W, and with a 30% transient margin, 550W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 4070's memory bus (192-bit) and bandwidth (504 GB/s) describe its own video memory, meaning how fast the card reads its 12 GB of GDDR6X, not the PCIe link to the processor. The PCIe link depends on the card, the processor and the motherboard slot together; our catalogue does not record PCIe generation or lane count, so the model does not estimate it. It matters most for cards with an eight-lane interface in older PCIe 3.0 boards: check the card's and the board's specifications.
SYSTEM MEMORY
This page assumes 16 GB in dual channel. At 1440p, the resolution recommended above, that meets the model's capacity target of 16 GB (enough for three in four of the games it covers), so more capacity would add little or nothing there. The target stays at 16 GB even at 4K, so a larger kit is for heavy multitasking or mods, not for these games. Memory speed and a second channel act on the processor's ceiling instead: they matter in the games the CPU limits, by an amount that depends on the game, and the calculator lets you enter your own kit.
HOW THIS PAGE IS CALCULATED
ENGINE v2026.08 · 2026-09-11CALCULATED, NOT WRITTEN
Every figure and every sentence comes from the same deterministic engine, driven by the catalogue specifications. That is what makes it reproducible: with the same engine version (2026.08) and the same catalogue, the same pairing always gives the same result. When either changes, the version and date above change with it, and the changelog says why.
WHERE THE DATA COMES FROM
Specifications come from the official AMD, Intel and NVIDIA datasheets together with PassMark and TechPowerUp. The gaming indices are calibrated against frame rates published by review outlets (TechPowerUp, TechSpot / Hardware Unboxed, Tom's Hardware, Gamers Nexus, Digital Foundry) rather than synthetic scores. That data is compiled, not measured here: this site runs no test bench of its own.
STATED LIMITS
Figures estimate native raster performance at high/ultra quality, with no ray tracing, upscaling or frame generation. We do not yet publish an externally validated error margin — the accuracy page states exactly where that stands.

FREQUENTLY ASKED QUESTIONS
5Does the AMD Ryzen 5 5600G bottleneck the NVIDIA RTX 4070?
At 1080p the Ryzen 5 5600G becomes the limiting part (~21% CPU bottleneck), whereas at 4K the RTX 4070 is the limiting part (~38% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 70% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1440p, where AAA games average 64 FPS.
How many FPS do the Ryzen 5 5600G and RTX 4070 get at 1080p?
At 1080p this combination averages about 87 FPS in AAA games and around 276 FPS in esports titles. In Valorant we estimate up to 438 FPS.
Is this pairing good for 4K gaming?
Playable rather than smooth: about 42 FPS on average in AAA titles at 4K, with the RTX 4070 setting the limit. Upscaling (DLSS, FSR or XeSS) or lower settings are the usual way to reach 60 FPS.
What power supply do I need for the Ryzen 5 5600G and RTX 4070?
With an estimated combined draw of 265W across CPU and GPU, we recommend at least a 550W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RTX 4070's 12 GB of VRAM enough?
12 GB covers all 11 tracked games at 1440p in the model; at 4K, 3 of them would need more, which costs frames or texture quality in those titles.
