DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThe Intel Core i5-9400F and the AMD RX 9060 8GB each bring their own character. Below you'll see whether the union is balanced or whether one component wastes the other, with estimated FPS, power draw and recommendations tailored to this specific pair.
Verdict: 1440p is playable, not smooth
At 1080p the Core i5-9400F becomes the limiting part (~17% CPU bottleneck), whereas at 4K the RX 9060 8GB is the limiting part (~49% GPU bottleneck). No 16:9 size keeps this pair above 60 FPS in demanding titles. 1440p is the highest that stays playable, at roughly 38 FPS on average in AAA. Esports is a different story — around 172 FPS at 1080p.
As you climb from 1080p to 4K, the load shifts from the processor toward the graphics card: every extra pixel lands on the RX 9060 8GB. Here, efficiency moves from 83% at 1080p to 51% at 4K — which shows the part the frame rate depends on at each end.
In esports titles like Valorant this pair flies — around 275 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~10 FPS at 4K, which is where the RX 9060 8GB's ceiling really shows. Overall, expect about 54 FPS average in AAA games at 1080p and around 22 FPS at 4K.
[CPU] Core i5-9400F
The Core i5-9400F (46/100 on the model's gaming scale) brings 6 cores and 6 threads and determines how many frames per second the system can prepare.
[GPU] RX 9060 8GB
On the graphics side, the RX 9060 8GB rates 23/100 for gaming in this model. Its 8 GB of GDDR6 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.
A detail that's easy to overlook: The graphics card is about 6 years newer than the processor, so watch that the Core i5-9400F doesn't fall short in the most CPU-dependent games. You're combining an Intel platform with an AMD GPU — a perfectly valid mix that imposes no penalty.
DO YOU NEED TO CHANGE ANYTHING?
At 1440p the RX 9060 8GB sets the frame rate, but only by 10%, which is inside the normal range. No card in our catalogue clears the bar we use for a recommendation: at least 25% more frames while the Core i5-9400F still keeps it fully fed. The closest, the NVIDIA RTX 5090, adds about 40% in this model. So there is no card we would tell you to buy for this pairing.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Core i5-9400F (65W) and RX 9060 8GB (132W) add up to roughly 197W under load. Adding 150W for the rest of the system gives 347W, and with a 30% transient margin, 550W is the safe figure.
VIDEO MEMORY AND PCIe
The RX 9060 8GB's memory bus (128-bit) and bandwidth (288 GB/s) describe its own video memory, meaning how fast the card reads its 8 GB of GDDR6, 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 Intel Core i5-9400F bottleneck the AMD RX 9060 8GB?
At 1080p the Core i5-9400F becomes the limiting part (~17% CPU bottleneck), whereas at 4K the RX 9060 8GB is the limiting part (~49% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 62% average efficiency across the 12 resolutions our model tests. 1440p is the highest resolution that stays playable, at about 38 FPS on average in AAA titles.
How many FPS do the Core i5-9400F and RX 9060 8GB get at 1080p?
At 1080p this combination averages about 54 FPS in AAA games and around 172 FPS in esports titles. In Valorant we estimate up to 275 FPS.
Is this pairing good for 4K gaming?
Not for AAA titles at native high settings: about 22 FPS on average at 4K. It would take upscaling, much lower settings or faster hardware.
What power supply do I need for the Core i5-9400F and RX 9060 8GB?
With an estimated combined draw of 197W across CPU and GPU, we recommend at least a 550W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RX 9060 8GB's 8 GB of VRAM enough?
8 GB falls short at 1440p for 3 of the 11 games the model tracks, and for 6 at 4K. In those titles expect to lower texture settings, or to see frame-time spikes if you do not.
