DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThis page breaks down, number by number, what happens when you run an Intel Core i5-11600K alongside an AMD RX 9060 XT 16GB. The processor scores 63/100 and the graphics card 28/100 in our model — the interesting part is how they split the workload at each resolution.
Quick take: 1080p is the resolution to target
At 1080p the two stay well balanced, whereas at 4K the RX 9060 XT 16GB is the limiting part (~60% GPU bottleneck). Of the common 16:9 sizes, the highest this pair holds above 60 FPS in AAA titles is 1080p, where it averages 64 FPS — that is the resolution worth buying a monitor for. Across every resolution tested, ultrawides included, the system runs at 57% average efficiency.
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 XT 16GB. Here, efficiency moves from 96% at 1080p to 40% 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 477 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~14 FPS at 4K, which is where the RX 9060 XT 16GB's ceiling really shows. Overall, expect about 64 FPS average in AAA games at 1080p and around 28 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] RX 9060 XT 16GB
On the graphics side, the RX 9060 XT 16GB rates 28/100 for gaming in this model. Its 16 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.
On the chemistry of the pair: The graphics card is about 4 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 AMD GPU — a perfectly valid mix that imposes no penalty.
WHAT TO CHANGE, AND WHAT IT COSTS
At 1440p the RX 9060 XT 16GB 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 AMD RX 6950 XT: about 28% 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.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Core i5-11600K (125W) and RX 9060 XT 16GB (160W) add up to roughly 285W under load. Adding 150W for the rest of the system gives 435W, and with a 30% transient margin, 600W is the safe figure.
VIDEO MEMORY AND PCIe
The RX 9060 XT 16GB's memory bus (128-bit) and bandwidth (320 GB/s) describe its own video memory, meaning how fast the card reads its 16 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 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 · 2026-09-11CALCULATED, 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 i5-11600K bottleneck the AMD RX 9060 XT 16GB?
At 1080p the two stay well balanced, whereas at 4K the RX 9060 XT 16GB is the limiting part (~60% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 57% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1080p, where AAA games average 64 FPS.
How many FPS do the Core i5-11600K and RX 9060 XT 16GB get at 1080p?
At 1080p this combination averages about 64 FPS in AAA games and around 289 FPS in esports titles. In Valorant we estimate up to 477 FPS.
Is this pairing good for 4K gaming?
Not for AAA titles at native high settings: about 28 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 RX 9060 XT 16GB?
With an estimated combined draw of 285W across CPU and GPU, we recommend at least a 600W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RX 9060 XT 16GB'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.
