DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEPairing the Intel Core Ultra 5 245 (80/100 on our gaming index) with the NVIDIA RTX 4070 Ti (52/100) raises one practical question: do they pull together, or does one hold the other back? We ran this exact combination across all supported resolutions to answer it with numbers rather than guesswork.
Quick take: 1440p is the resolution to target
At 1080p the Core Ultra 5 245 becomes the limiting part (~9% CPU bottleneck), whereas at 4K the RTX 4070 Ti is the limiting part (~41% GPU bottleneck). Of the common 16:9 sizes, the highest this pair holds above 60 FPS in AAA titles is 1440p, where it averages 75 FPS — that is the resolution worth buying a monitor for. Across every resolution tested, ultrawides included, the system runs at 72% average efficiency.
Think of resolution as a dial that splits the weight between CPU and GPU. Drop to 1080p and you wring out the RTX 4070 Ti while leaning harder on the Core Ultra 5 245; push to 4K and the opposite happens. Synergy here swings between 59% and 91% depending on where you sit.
Down to real numbers: In esports titles like Valorant this pair flies — around 725 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~28 FPS at 4K, which is where the RTX 4070 Ti's ceiling really shows. Overall, expect about 102 FPS average in AAA games at 1080p and around 49 FPS at 4K.
[CPU] Core Ultra 5 245
The Core Ultra 5 245 scores 80/100 on this model's gaming scale, with 14 cores and 14 threads. In this pairing its job is to serve frames fast enough to never leave the graphics card waiting.
[GPU] RTX 4070 Ti
On the graphics side, the RTX 4070 Ti rates 52/100 for gaming in this model. Its 12 GB of GDDR6X set how far it can go on resolution and texture quality before video memory runs short. The higher the resolution, the more of the frame rate depends on it.
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.
DO YOU NEED TO CHANGE ANYTHING?
At 1440p the RTX 4070 Ti sets the frame rate, but only by 11%, 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 Ultra 5 245 still keeps it fully fed. The closest, the NVIDIA RTX 5090, adds about 32% 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 Ultra 5 245 (65W) and RTX 4070 Ti (285W) add up to roughly 350W under load. Adding 150W for the rest of the system gives 500W, and with a 30% transient margin, 650W is the safe figure.
VIDEO MEMORY AND PCIe
The RTX 4070 Ti'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 5 245 bottleneck the NVIDIA RTX 4070 Ti?
At 1080p the Core Ultra 5 245 becomes the limiting part (~9% CPU bottleneck), whereas at 4K the RTX 4070 Ti is the limiting part (~41% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 72% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1440p, where AAA games average 75 FPS.
How many FPS do the Core Ultra 5 245 and RTX 4070 Ti get at 1080p?
At 1080p this combination averages about 102 FPS in AAA games and around 432 FPS in esports titles. In Valorant we estimate up to 725 FPS.
Is this pairing good for 4K gaming?
Playable rather than smooth: about 49 FPS on average in AAA titles at 4K, with the RTX 4070 Ti 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 5 245 and RTX 4070 Ti?
With an estimated combined draw of 350W 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 Ti'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.
