DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThe Intel Core i9-10900K and the NVIDIA RTX 4070 Ti SUPER 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.
Bottom line: this pair carries 1440p
At 1080p the Core i9-10900K becomes the limiting part (~30% CPU bottleneck), whereas at 4K the RTX 4070 Ti SUPER is the limiting part (~26% GPU bottleneck). One number decides the purchase: 1440p is the most demanding of the standard 16:9 sizes that still sustains 81 FPS on average in AAA games, above the 60 FPS bar we treat as smooth. Step up a rung and the frame rate drops below that mark.
As you climb from 1080p to 4K, the load shifts from the processor toward the graphics card: every extra pixel lands on the RTX 4070 Ti SUPER. Here, efficiency moves from 70% at 1080p to 74% at 4K — which shows the part the frame rate depends on at each end.
Translated into actual games: 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 ~33 FPS at 4K, which is where the RTX 4070 Ti SUPER's ceiling really shows. Overall, expect about 100 FPS average in AAA games at 1080p and around 54 FPS at 4K.
[CPU] Core i9-10900K
On the CPU side: the Core i9-10900K rates 63/100 for gaming in this model and brings 10 cores and 20 threads. At lower resolutions it's the one setting the pace for the whole system.
[GPU] RTX 4070 Ti SUPER
The RTX 4070 Ti SUPER scores 57/100 on this model's gaming scale. Its 16 GB of GDDR6X set how far it can go on resolution and texture quality before video memory runs short. It draws every pixel, so its weight grows the higher you push the resolution.
Beyond the FPS: The graphics card is about 4 years newer than the processor, so watch that the Core i9-10900K 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 neither part appreciably holds the other back, so there is nothing you need to change. The Core i9-10900K and the RTX 4070 Ti SUPER stand as they are; a 750W supply gives the build headroom.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Core i9-10900K (125W) and RTX 4070 Ti SUPER (285W) add up to roughly 410W under load. Adding 150W for the rest of the system gives 560W, and with a 30% transient margin, 750W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 4070 Ti SUPER's memory bus (256-bit) and bandwidth (672.3 GB/s) describe its own video memory, meaning how fast the card reads its 16 GB of GDDR6X, 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 1440p, 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 i9-10900K bottleneck the NVIDIA RTX 4070 Ti SUPER?
At 1080p the Core i9-10900K becomes the limiting part (~30% CPU bottleneck), whereas at 4K the RTX 4070 Ti SUPER is the limiting part (~26% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 77% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1440p, where AAA games average 81 FPS.
How many FPS do the Core i9-10900K and RTX 4070 Ti SUPER get at 1080p?
At 1080p this combination averages about 100 FPS in AAA games and around 298 FPS in esports titles. In Valorant we estimate up to 477 FPS.
Is this pairing good for 4K gaming?
Playable rather than smooth: about 54 FPS on average in AAA titles at 4K, with the RTX 4070 Ti SUPER setting the limit. Upscaling (DLSS, FSR or XeSS) or lower settings are the usual way to reach 60 FPS.
What power supply do I need for the Core i9-10900K and RTX 4070 Ti SUPER?
With an estimated combined draw of 410W across CPU and GPU, we recommend at least a 750W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RTX 4070 Ti SUPER'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.
