DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThis page breaks down, number by number, what happens when you run an AMD Ryzen 5 3600 alongside an NVIDIA RTX 4080 SUPER. The processor scores 52/100 and the graphics card 69/100 in our model — the interesting part is how they split the workload at each resolution.
Quick take: 4K is the resolution to target
At 1080p the Ryzen 5 3600 becomes the limiting part (~49% CPU bottleneck), whereas at 4K the two stay well balanced. One number decides the purchase: 4K is the most demanding of the standard 16:9 sizes that still sustains 63 FPS on average in AAA games, above the 60 FPS bar we treat as smooth. Step up a rung and the frame rate drops below that mark.
As you climb from 1080p to 4K, the load shifts from the processor toward the graphics card: every extra pixel lands on the RTX 4080 SUPER. Here, efficiency moves from 51% at 1080p to 98% at 4K — which shows the part the frame rate depends on at each end.
Down to real numbers: In esports titles like Valorant this pair flies — around 341 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~41 FPS at 4K, which is where the RTX 4080 SUPER's ceiling really shows. Overall, expect about 90 FPS average in AAA games at 1080p and around 63 FPS at 4K.
[CPU] Ryzen 5 3600
The Ryzen 5 3600 (52/100 on the model's gaming scale) brings 6 cores and 12 threads and determines how many frames per second the system can prepare. With 32 MB of L3 cache it has room to keep the RTX 4080 SUPER well fed.
[GPU] RTX 4080 SUPER
The RTX 4080 SUPER scores 69/100 on this model's gaming scale. Its 16 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.
A detail that's easy to overlook: The graphics card is about 5 years newer than the processor, so watch that the Ryzen 5 3600 doesn't fall short in the most CPU-dependent games. You're combining an AMD platform with an NVIDIA GPU — a perfectly valid mix that imposes no penalty.
WHAT TO CHANGE, AND WHAT IT COSTS
At 1440p the Ryzen 5 3600 sets the frame rate and leaves part of the RTX 4080 SUPER idle. The cheapest processor in our catalogue that keeps the card fully fed and clears our bar (at least 10% more frames) is the Intel Core i7-12700F: about 49% more in this model, with this card and 16 GB. It uses a different socket (LGA1700 instead of AM4), so the cost includes a motherboard.
The gain is the model's estimate at 2560x1440 with 16 GB, not a measurement of your PC, and prices change: check them at the retailer before deciding.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Ryzen 5 3600 (65W) and RTX 4080 SUPER (320W) add up to roughly 385W under load. Adding 150W for the rest of the system gives 535W, and with a 30% transient margin, 700W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 4080 SUPER's memory bus (256-bit) and bandwidth (736.3 GB/s) describe its own video memory, meaning how fast the card reads its 16 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 4K, 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. 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 3600 bottleneck the NVIDIA RTX 4080 SUPER?
At 1080p the Ryzen 5 3600 becomes the limiting part (~49% CPU bottleneck), whereas at 4K the two stay well balanced. Overall, there is some mismatch depending on resolution, with 75% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 4K, where AAA games average 63 FPS.
How many FPS do the Ryzen 5 3600 and RTX 4080 SUPER get at 1080p?
At 1080p this combination averages about 90 FPS in AAA games and around 220 FPS in esports titles. In Valorant we estimate up to 341 FPS.
Is this pairing good for 4K gaming?
Yes. At 4K this pairing averages about 63 FPS in AAA titles, at or above the 60 FPS we treat as smooth.
What power supply do I need for the Ryzen 5 3600 and RTX 4080 SUPER?
With an estimated combined draw of 385W across CPU and GPU, we recommend at least a 700W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RTX 4080 SUPER's 16 GB of VRAM enough?
In the model, 16 GB covers all 11 games it tracks even at 4K with high textures, so video memory is not the constraint for this pairing.
