Intel Core i5-14600K + GeForce RTX 4070 Super Bottleneck Calculator
A specs-based bottleneck estimate for pairing the Intel Core i5-14600K with the GeForce RTX 4070 Super, broken down by resolution — plus what it means for your build.
Quick Summary
The limiting part shifts with resolution for the Intel Core i5-14600K and GeForce RTX 4070 Super: our estimate is balanced at 1080p, GPU-limited at 1440p (~31%) and GPU-limited at 4K (~57%). 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 | Estimated Bottleneck | Likely Limiting Part |
|---|---|---|
| 1080p (Full HD) | 1% | Balanced |
| 1440p (QHD) | 31% | GeForce RTX 4070 Super (GPU) |
| 4K (UHD) | 57% | GeForce RTX 4070 Super (GPU) |
1080p (Full HD): At 1080p (Full HD), the Intel Core i5-14600K and GeForce RTX 4070 Super are well matched — neither part is holding the other back in any meaningful way for most games.
1440p (QHD): At 1440p (QHD), the GeForce RTX 4070 Super is the more likely limiting factor — our estimate puts the GPU-side bottleneck at roughly 31%. The Intel Core i5-14600K has more headroom than the graphics card can use at this resolution.
4K (UHD): At 4K (UHD), the GeForce RTX 4070 Super is the more likely limiting factor — our estimate puts the GPU-side bottleneck at roughly 57%. The Intel Core i5-14600K has more headroom than the graphics card can use at this resolution.
Recommended Settings & Upgrade Path
The GeForce RTX 4070 Super is the more limiting part of this pairing. 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 GeForce RTX 4070 Super’s class (Mid-range / 1440p), the Intel Core i5-14600K + GeForce RTX 4070 Super suits 1080p and 1440p gaming. For 4K the GeForce RTX 4070 Super sits below the GPU level our PC Upgrade Calculator looks for.
The GeForce RTX 4070 Super is the part that limits most at 1440p, so a graphics card upgrade changes this estimate most. If you want a stronger 1440p setup, the smallest step up in our database that brings 1440p under 15% with the Intel Core i5-14600K is the Radeon RX 9070 XT, which our engine rates as CPU-limited at 1080p (~22%), GPU-limited at 1440p (~13%) and GPU-limited at 4K (~46%).

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%) and GPU-limited at 4K (~57%), so the processor isn’t what holds frame rates back in most games. These are specs-based estimates, 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 i9-13900K; our engine rates it with the GeForce RTX 4070 Super as GPU-limited at 1080p (~6%), GPU-limited at 1440p (~36%) and GPU-limited at 4K (~60%), compared with balanced at 1080p, GPU-limited at 1440p (~31%) and GPU-limited at 4K (~57%) 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.
