DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEAre the Intel Core i7-8700K and the NVIDIA RTX 4060 Ti 8GB a good match? To find out we modelled the pair from 1080p up to 4K, cross-referencing the model's gaming scores for the CPU (54/100) and the GPU (31/100), calibrated against measured benchmarks rather than synthetic scores, with the demand profile of each game.
Verdict: play this build at 1080p
At 1080p the Core i7-8700K becomes the limiting part (~12% CPU bottleneck), whereas at 4K the RTX 4060 Ti 8GB is the limiting part (~51% GPU bottleneck). We put the target at 1080p: the highest of the usual 16:9 sizes where AAA titles still return 69 FPS, which is above 60. The table below breaks out all twelve resolutions on their own, ultrawide formats included.
Resolution reshuffles the priorities. At 1080p the Core i7-8700K's single-thread speed calls the shots; at 4K it's the raw muscle of the RTX 4060 Ti 8GB that matters. That shift shows up in the numbers: 88% efficiency at 1080p versus 49% at 4K.
Translated into actual games: In esports titles like Valorant this pair flies — around 365 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 RTX 4060 Ti 8GB's ceiling really shows. Overall, expect about 69 FPS average in AAA games at 1080p and around 29 FPS at 4K.
[CPU] Core i7-8700K
The Core i7-8700K scores 54/100 on this model's gaming scale, with 6 cores and 12 threads. In this pairing its job is to serve frames fast enough to never leave the graphics card waiting.
[GPU] RTX 4060 Ti 8GB
The RTX 4060 Ti 8GB (31/100 on the model's gaming scale) supplies the raster muscle of the build. Its 8 GB of GDDR6 set how far it can go on resolution and texture quality before video memory runs short.
Beyond the FPS: The graphics card is about 6 years newer than the processor, so watch that the Core i7-8700K 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.
DO YOU NEED TO CHANGE ANYTHING?
At 1440p the RTX 4060 Ti 8GB sets the frame rate, but only by 14%, which is inside the normal range. No card in our catalogue clears the bar we use for a recommendation: at least 25% more frames while the Core i7-8700K still keeps it fully fed. The closest, the NVIDIA RTX 5090, adds about 46% 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 i7-8700K (95W) and RTX 4060 Ti 8GB (160W) add up to roughly 255W under load. Adding 150W for the rest of the system gives 405W, and with a 30% transient margin, 550W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 4060 Ti 8GB's memory bus (128-bit) and bandwidth (288 GB/s) describe its own video memory, meaning how fast the card reads its 8 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 i7-8700K bottleneck the NVIDIA RTX 4060 Ti 8GB?
At 1080p the Core i7-8700K becomes the limiting part (~12% CPU bottleneck), whereas at 4K the RTX 4060 Ti 8GB is the limiting part (~51% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 63% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1080p, where AAA games average 69 FPS.
How many FPS do the Core i7-8700K and RTX 4060 Ti 8GB get at 1080p?
At 1080p this combination averages about 69 FPS in AAA games and around 234 FPS in esports titles. In Valorant we estimate up to 365 FPS.
Is this pairing good for 4K gaming?
Not for AAA titles at native high settings: about 29 FPS on average at 4K. It would take upscaling, much lower settings or faster hardware.
What power supply do I need for the Core i7-8700K and RTX 4060 Ti 8GB?
With an estimated combined draw of 255W across CPU and GPU, we recommend at least a 550W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RTX 4060 Ti 8GB's 8 GB of VRAM enough?
8 GB falls short at 1440p for 3 of the 11 games the model tracks, and for 6 at 4K. In those titles expect to lower texture settings, or to see frame-time spikes if you do not.
