DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThe Intel Core i5-10400F and the NVIDIA RTX 2060 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
The RTX 2060 sets the limit at both ends of the range: a ~12% GPU bottleneck at 1080p that widens to ~70% at 4K. Straight up: this combination does not deliver a steady 60 FPS in AAA games. 1440p at about 31 FPS is the best compromise, and dropping a setting or two — or turning on DLSS/FSR — turns that into a comfortable frame rate.
Think of resolution as a dial that splits the weight between CPU and GPU. Drop to 1080p and you wring out the RTX 2060 while leaning harder on the Core i5-10400F; push to 4K and the opposite happens. Synergy here swings between 30% and 88% depending on where you sit.
Translated into actual games: 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 ~8 FPS at 4K, which is where the RTX 2060's ceiling really shows. Overall, expect about 47 FPS average in AAA games at 1080p and around 17 FPS at 4K.
[CPU] Core i5-10400F
On the CPU side: the Core i5-10400F rates 52/100 for gaming in this model and brings 6 cores and 12 threads. At lower resolutions it's the one setting the pace for the whole system.
[GPU] RTX 2060
The RTX 2060 scores 18/100 on this model's gaming scale. Its 6 GB of GDDR6 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: 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.
DO YOU NEED TO CHANGE ANYTHING?
At 1440p the RTX 2060 sets the frame rate. No card in our catalogue clears the bar we use for a recommendation: at least 25% more frames while the Core i5-10400F still keeps it fully fed. The closest, the NVIDIA RTX 5090, adds about 99% 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 i5-10400F (65W) and RTX 2060 (160W) add up to roughly 225W under load. Adding 150W for the rest of the system gives 375W, and with a 30% transient margin, 550W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 2060's memory bus (192-bit) and bandwidth (336 GB/s) describe its own video memory, meaning how fast the card reads its 6 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 i5-10400F bottleneck the NVIDIA RTX 2060?
The RTX 2060 sets the limit at both ends of the range: a ~12% GPU bottleneck at 1080p that widens to ~70% at 4K. Overall, the GPU is the limit at high resolution, with 48% average efficiency across the 12 resolutions our model tests. 1440p is the highest resolution that stays playable, at about 31 FPS on average in AAA titles.
How many FPS do the Core i5-10400F and RTX 2060 get at 1080p?
At 1080p this combination averages about 47 FPS in AAA games and around 206 FPS in esports titles. In Valorant we estimate up to 341 FPS.
Is this pairing good for 4K gaming?
Not for AAA titles at native high settings: about 17 FPS on average at 4K. It would take upscaling, much lower settings or faster hardware.
What power supply do I need for the Core i5-10400F and RTX 2060?
With an estimated combined draw of 225W across CPU and GPU, we recommend at least a 550W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RTX 2060's 6 GB of VRAM enough?
6 GB falls short at 1440p for 6 of the 11 games the model tracks, and for 7 at 4K. In those titles expect to lower texture settings, or to see frame-time spikes if you do not.
