DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThis page breaks down, number by number, what happens when you run an Intel Core Ultra 7 270K Plus alongside an NVIDIA RTX 4070 SUPER. The processor scores 88/100 and the graphics card 49/100 in our model — the interesting part is how they split the workload at each resolution.
Straight answer: aim for 1440p
At 1080p the two stay well balanced, whereas at 4K the RTX 4070 SUPER is the limiting part (~45% GPU bottleneck). Of the common 16:9 sizes, the highest this pair holds above 60 FPS in AAA titles is 1440p, where it averages 71 FPS — that is the resolution worth buying a monitor for. Across every resolution tested, ultrawides included, the system runs at 68% average efficiency.
Resolution reshuffles the priorities. At 1080p the Core Ultra 7 270K Plus's single-thread speed calls the shots; at 4K it's the raw muscle of the RTX 4070 SUPER that matters. That shift shows up in the numbers: 100% efficiency at 1080p versus 55% at 4K.
Translated into actual games: In esports titles like Valorant this pair flies — around 856 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~26 FPS at 4K, which is where the RTX 4070 SUPER's ceiling really shows. Overall, expect about 98 FPS average in AAA games at 1080p and around 46 FPS at 4K.
[CPU] Core Ultra 7 270K Plus
The Core Ultra 7 270K Plus (88/100 on the model's gaming scale) brings 24 cores and 24 threads and determines how many frames per second the system can prepare. With 36 MB of L3 cache it has room to keep the RTX 4070 SUPER well fed.
[GPU] RTX 4070 SUPER
The RTX 4070 SUPER scores 49/100 on this model's gaming scale. Its 12 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.
A detail that's easy to overlook: Both parts come from nearby generations, which usually means a natural pairing with no platform surprises. You're combining an Intel platform with an NVIDIA GPU — a perfectly valid mix that imposes no penalty.
WHAT TO CHANGE, AND WHAT IT COSTS
At 1440p the RTX 4070 SUPER sets the frame rate, and the Core Ultra 7 270K Plus can drive a faster card. The cheapest card that clears our bar for a recommendation (at least 25% more frames) is the NVIDIA RTX 4090: about 34% more in this model, with this processor and 16 GB.
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 Ultra 7 270K Plus (125W) and RTX 4070 SUPER (220W) add up to roughly 345W under load. Adding 150W for the rest of the system gives 495W, and with a 30% transient margin, 650W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 4070 SUPER's memory bus (192-bit) and bandwidth (504 GB/s) describe its own video memory, meaning how fast the card reads its 12 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 Ultra 7 270K Plus bottleneck the NVIDIA RTX 4070 SUPER?
At 1080p the two stay well balanced, whereas at 4K the RTX 4070 SUPER is the limiting part (~45% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 68% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1440p, where AAA games average 71 FPS.
How many FPS do the Core Ultra 7 270K Plus and RTX 4070 SUPER get at 1080p?
At 1080p this combination averages about 98 FPS in AAA games and around 493 FPS in esports titles. In Valorant we estimate up to 856 FPS.
Is this pairing good for 4K gaming?
Playable rather than smooth: about 46 FPS on average in AAA titles at 4K, with the RTX 4070 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 Ultra 7 270K Plus and RTX 4070 SUPER?
With an estimated combined draw of 345W across CPU and GPU, we recommend at least a 650W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RTX 4070 SUPER's 12 GB of VRAM enough?
12 GB covers all 11 tracked games at 1440p in the model; at 4K, 3 of them would need more, which costs frames or texture quality in those titles.
