DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEPairing the Intel Core i3-14100F (66/100 on our gaming index) with the NVIDIA RTX 4080 SUPER (69/100) 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: 4K is the resolution to target
At 1080p the Core i3-14100F becomes the limiting part (~35% CPU bottleneck), whereas at 4K the RTX 4080 SUPER is the limiting part (~12% GPU bottleneck). 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.
Think of resolution as a dial that splits the weight between CPU and GPU. Drop to 1080p and you wring out the RTX 4080 SUPER while leaning harder on the Core i3-14100F; push to 4K and the opposite happens. Synergy here swings between 88% and 65% depending on where you sit.
Down to real numbers: In esports titles like Valorant this pair flies — around 518 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 99 FPS average in AAA games at 1080p and around 63 FPS at 4K.
[CPU] Core i3-14100F
On the CPU side: the Core i3-14100F rates 66/100 for gaming in this model and brings 4 cores and 8 threads. At lower resolutions it's the one setting the pace for the whole system.
[GPU] RTX 4080 SUPER
On the graphics side, the RTX 4080 SUPER rates 69/100 for gaming in this model. Its 16 GB of GDDR6X set how far it can go on resolution and texture quality before video memory runs short. The higher the resolution, the more of the frame rate depends on it.
Beyond the FPS: Both parts come from nearby generations, which usually means a natural pairing with no platform surprises. You're combining an Intel platform with an NVIDIA GPU — a perfectly valid mix that imposes no penalty.
WHAT TO CHANGE, AND WHAT IT COSTS
At 1440p the Core i3-14100F 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 19% more in this model, with this card and 16 GB.
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.

BOTTLENECK BY RESOLUTION
SYNERGY · AVERAGE FPSYour CPU (Core i3-14100F) cannot feed the RTX 4080 SUPER fast enough at 1920x1080. The GPU sits waiting for frames, causing stutter and noticeable drops. A CPU upgrade is the highest-impact change you can make.

Your CPU (Core i3-14100F) introduces a slight limitation at 3440x1440 (Ultrawide 21:9). Real-world impact is small and both components work well together.
Your CPU (Core i3-14100F) and GPU (RTX 4080 SUPER) are an exceptionally balanced match for gaming at 5120x1440 (Super Ultrawide 32:9). No realistic component swap would meaningfully improve this build.
Your GPU (RTX 4080 SUPER) is a slight limiting factor at 4K, with limited real-world impact. Most titles will run smoothly.
ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Core i3-14100F (60W) and RTX 4080 SUPER (320W) add up to roughly 380W under load. Adding 150W for the rest of the system gives 530W, 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 Intel Core i3-14100F bottleneck the NVIDIA RTX 4080 SUPER?
At 1080p the Core i3-14100F becomes the limiting part (~35% CPU bottleneck), whereas at 4K the RTX 4080 SUPER is the limiting part (~12% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 79% 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 Core i3-14100F and RTX 4080 SUPER get at 1080p?
At 1080p this combination averages about 99 FPS in AAA games and around 313 FPS in esports titles. In Valorant we estimate up to 518 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, with the RTX 4080 SUPER setting the limit.
What power supply do I need for the Core i3-14100F and RTX 4080 SUPER?
With an estimated combined draw of 380W 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.
