DEEP-DIVE ANALYSIS

GENERATED BY THE ENGINE

The Intel Core i5-11600K and the NVIDIA RTX 3050 6GB 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.

Straight answer: 1080p, at about 31 FPS in AAA

The RTX 3050 6GB sets the limit at both ends of the range: a ~48% GPU bottleneck at 1080p that widens to ~85% at 4K. Straight up: this combination does not deliver a steady 60 FPS in AAA games. 1080p 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 3050 6GB while leaning harder on the Core i5-11600K; push to 4K and the opposite happens. Synergy here swings between 15% and 52% depending on where you sit.

Down to real numbers: In esports titles like Valorant this pair flies — around 431 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~4 FPS at 4K, which is where the RTX 3050 6GB's ceiling really shows. Overall, expect about 31 FPS average in AAA games at 1080p and around 10 FPS at 4K.

[CPU] Core i5-11600K

The Core i5-11600K (63/100 on the model's gaming scale) brings 6 cores and 12 threads and determines how many frames per second the system can prepare.

[GPU] RTX 3050 6GB

The RTX 3050 6GB (11/100 on the model's gaming scale) supplies the raster muscle of the build. Its 6 GB of GDDR6 set how far it can go on resolution and texture quality before video memory runs short.

On the chemistry of the pair: The graphics card is about 3 years newer than the processor, so watch that the Core i5-11600K doesn't fall short in the most CPU-dependent games. 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 RTX 3050 6GB sets the frame rate, and the Core i5-11600K can drive a faster card. The cheapest card that clears our bar for a recommendation (at least 25% more frames) is the Intel Arc A580: about 26% more in this model, with this processor and 16 GB. This processor keeps up with cards up to the NVIDIA RTX 4070 SUPER; anything between the two is an upgrade that gets used, and beyond that card the processor becomes the limit.

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.

SYSTEM DIAGNOSTICS

POWER · VRAM & PCIe · RAM

POWER ESTIMATION

Combined TDP:195 W
Min. Recommended PSU:550 W

The Core i5-11600K (125W) and RTX 3050 6GB (70W) add up to roughly 195W under load. Adding 150W for the rest of the system gives 345W, and with a 30% transient margin, 550W is the safe figure.

VIDEO MEMORY AND PCIe

Memory bus (VRAM):96-bit
Memory bandwidth:168 GB/s
PCIe link:Not recorded

The RTX 3050 6GB's memory bus (96-bit) and bandwidth (168 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 · dual channel
Model target at 1080p:16 GB

This page assumes 16 GB in dual channel. At 1080p, 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 · 2026-09-11

CALCULATED, 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

5
Does the Intel Core i5-11600K bottleneck the NVIDIA RTX 3050 6GB?

The RTX 3050 6GB sets the limit at both ends of the range: a ~48% GPU bottleneck at 1080p that widens to ~85% at 4K. Overall, the GPU is the limit at high resolution, with 28% average efficiency across the 12 resolutions our model tests. 1080p is the highest resolution that stays playable, at about 31 FPS on average in AAA titles.

How many FPS do the Core i5-11600K and RTX 3050 6GB get at 1080p?

At 1080p this combination averages about 31 FPS in AAA games and around 203 FPS in esports titles. In Valorant we estimate up to 431 FPS.

Is this pairing good for 4K gaming?

Not for AAA titles at native high settings: about 10 FPS on average at 4K. It would take upscaling, much lower settings or faster hardware.

What power supply do I need for the Core i5-11600K and RTX 3050 6GB?

With an estimated combined draw of 195W across CPU and GPU, we recommend at least a 550W 80+ Gold supply (ideally ATX 3.0) to run with headroom.

Is the RTX 3050 6GB'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.
