Intel Core i5-14600K + GeForce RTX 4070 Super Bottleneck at 1080p, 1440p and 4K
A bottleneck estimate for pairing the Intel Core i5-14600K with the GeForce RTX 4070 Super, built from our gaming-performance scores and broken down by resolution — plus what it means for your build.
Also covers the Intel Core i5-13600K with the GeForce RTX 4070 Super, which lands within a few points of these results.
Quick Summary
At 1440p (QHD), the resolution this card is built for, the RTX 4070 Super sets the frame rate, which is normal for gaming: the graphics card is fully used and the Core i5-14600K has about 31% of spare headroom. For higher frame rates here, a faster graphics card is what helps; a faster CPU would not. Across resolutions the limiting part shifts: our estimate is balanced at 1080p, GPU-limited at 1440p (~31% CPU headroom) and GPU-limited at 4K (~57% CPU headroom). As resolution rises the GPU has more pixels to draw per frame, so more of the load lands on the graphics card.
Estimate only: this bottleneck estimate is a simplified model meant to guide your decision, not a lab-measured result. Real-world numbers vary by brand, drivers, cooling, game engine and settings.

Bottleneck Estimate by Resolution
| Resolution | Estimate | Likely Limiting Part |
|---|---|---|
| 1080p (Full HD) | Balanced | Balanced |
| 1440p (QHD) | GPU-limited, normal (31% CPU headroom) | RTX 4070 Super (GPU) |
| 4K (UHD) | GPU-limited, normal (57% CPU headroom) | RTX 4070 Super (GPU) |
How to read this: a CPU bottleneck % is the share of the graphics card left idle (under 6% balanced, 6–14% mild, 15–29% noticeable, 30%+ severe). GPU-limited is normal; there the % is spare CPU headroom. Typical AAA game, high settings (how we estimate).
1080p (Full HD): The Core i5-14600K and RTX 4070 Super are well matched here.
1440p (QHD): The RTX 4070 Super is the limit, and the Core i5-14600K has about 31% to spare. For higher frame rates here, a faster graphics card is what helps; a faster CPU would not.
4K (UHD): The RTX 4070 Super is the limit, and the Core i5-14600K has about 57% to spare.
Core i5-14600K + RTX 4070 Super by Game Type
The game type changes the picture most at 1080p: in CPU-heavy games the Core i5-14600K becomes the limit (severe CPU bottleneck (31%)), while a typical AAA game at the same resolution reads balanced.
| Game type | 1080p | 1440p | 4K |
|---|---|---|---|
|
Typical AAA games
e.g. PUBG: Battlegrounds, Elden Ring and Red Dead Redemption 2 |
Balanced | GPU-limited | GPU-limited |
|
Esports games
e.g. League of Legends, Valorant and Counter-Strike 2 |
CPU ~8% | GPU-limited | GPU-limited |
|
CPU-heavy games
e.g. Minecraft: Java Edition and Baldur's Gate 3 |
CPU ~31% | Balanced | GPU-limited |
High settings throughout. Game types are rough classes, not per-game benchmarks: the linked pages list each game’s official requirements (all games we cover).
Recommended Settings & Upgrade Path
The RTX 4070 Super sets the frame rate in this pairing, which is the normal case for gaming. If you want more FPS before considering a GPU upgrade, lowering shadow quality, ambient occlusion and render resolution scale typically helps more than any other settings on a GPU-bound system.

Verdict
Going by this page’s estimates and the RTX 4070 Super’s class (Mid-range / 1440p), the Core i5-14600K + RTX 4070 Super suits 1080p and 1440p gaming. For 4K the RTX 4070 Super sits below the GPU level our PC Upgrade Calculator looks for.
The RTX 4070 Super sets the frame rate at 1440p while the CPU still has headroom, so a faster graphics card is the upgrade that adds the most FPS. If you want a stronger 1440p setup, the smallest step up among current cards in our database that uses most of the Core i5-14600K’s headroom at 1440p (under 15% left) is the Radeon RX 9070 XT, which our engine rates as a noticeable CPU bottleneck at 1080p (~22%), GPU-limited at 1440p (~13% CPU headroom) and GPU-limited at 4K (~46% CPU headroom).
Core i5-14600K or Core i5-13600K for the RTX 4070 Super?
The Core i5-14600K scores about 3% higher than the Intel Core i5-13600K in our gaming index. With the RTX 4070 Super that gap can only matter where the CPU is the limit.
Here the two stay within a few points of each other in every game type and resolution we estimate, so the Core i5-13600K already gets nearly everything the RTX 4070 Super can deliver. The Core i5-14600K mainly adds headroom for a faster graphics card later.
The Core i5-13600K + RTX 4070 Super lands within a few points of this page’s estimates in every game type and resolution, so this page covers both pairings.

Frequently Asked Questions
Is the Intel Core i5-14600K fast enough for the GeForce RTX 4070 Super?
Yes, by our bottleneck estimate. The Intel Core i5-14600K is not the limiting part at 1080p, 1440p or 4K with the GeForce RTX 4070 Super: the pairing is balanced at 1080p, GPU-limited at 1440p (~31% CPU headroom) and GPU-limited at 4K (~57% CPU headroom), so the processor isn’t what holds frame rates back in most games. These are estimates from our gaming-performance scores, not benchmark results.
Is 12GB of VRAM enough for the Intel Core i5-14600K + GeForce RTX 4070 Super?
Our GPU VRAM Calculator’s guideline is about 6GB at 1080p, 8GB at 1440p and 12GB at 4K for high textures, 2GB more for ultra, and about 2GB more again for ray tracing. The GeForce RTX 4070 Super’s 12GB covers high textures at 1080p, 1440p and 4K and ultra at 1080p and 1440p. Those are minimums; for comfortable headroom in newer games our VRAM guide suggests about 8GB at 1080p, 12GB at 1440p and 16GB at 4K. This card meets it at 1080p and 1440p. At 1440p, the highest resolution this pairing suits, that is enough even with ultra textures.
Can I upgrade from the Intel Core i5-14600K without changing the motherboard?
Yes, within LGA 1700. The strongest gaming CPU on that socket in our database is the Intel Core i9-14900K; our engine rates it with the GeForce RTX 4070 Super as GPU-limited at 1080p (~10% CPU headroom), GPU-limited at 1440p (~39% CPU headroom) and GPU-limited at 4K (~60%+ CPU headroom), compared with balanced at 1080p, GPU-limited at 1440p (~31% CPU headroom) and GPU-limited at 4K (~57% CPU headroom) for the Intel Core i5-14600K. Check your motherboard’s CPU support list first, as an older board may need a BIOS update. LGA 1700 boards take DDR4 or DDR5, depending on the board (never both).
What power supply does the Intel Core i5-14600K + GeForce RTX 4070 Super need?
Our PSU Calculator, with its default extras (2 RAM sticks, 2 drives, 3 fans, no overclock), estimates about 482W under load for this pair and recommends at least a 650W power supply. That counts the Intel Core i5-14600K at its 181W maximum boost power (125W TDP) and the GeForce RTX 4070 Super at 220W; NVIDIA’s own recommendation for the card is 650W. Pick 80+ Bronze or better; many GeForce RTX 4070 Super models use the 16-pin 12V-2x6 plug, so an ATX 3.1 unit with a native cable is the safe choice.
