Core i5-14400 + RTX 5070 bottleneck at 1080p, 1440p and 4K

Intel Core i5-14400 with NVIDIA GeForce RTX 5070

1080p

Well matched

The processor can prepare about 90% of the frames this card could draw.

1440p

The graphics card sets the pace

The processor could keep up with a graphics card about 30% faster.

The graphics card sets the pace, by a wide margin

The processor could keep up with a graphics card about 2.1 times as fast.

A balanced pair: at 1080p neither part is wasted, and at higher resolutions the graphics card sets the pace, which is where you want it.

An estimate for a typical game at high settings. Strategy, simulation and large multiplayer games lean on the processor more; lower settings and upscaling do too.

Does your PC deliver this?

These parts suit each other, so what decides your frame rate is whether your PC runs them as designed. Two PCs with the same parts can perform very differently. On a PC with these parts, Bottleneck checks, free:

Intel’s fix for 13th and 14th gen instability. Some Core i5-14400 processors are made on the chip that can wear out and turn unstable without a BIOS update; Bottleneck says which chip yours is, and whether it has the fix. What the fault is
Resizable BAR. Both parts support it, and it is often left switched off in the BIOS.
Hardware GPU scheduling. Frame generation on the RTX 5070 will not run without it.
The monitor’s refresh rate. A 144 Hz monitor left at 60 Hz holds every game to 60 frames a second.

Then play a game while it measures, and it tells you which part really set the pace, and for what share of the frames: measured on your PC, where this page can only estimate.

Current cards that are well matched with the Core i5-14400 at 1440p, fastest first.

Power supply

A 650 W power supply covers this pair: at full load the Core i5-14400, the RTX 5070 and the rest of the PC can draw up to about 458 W. The power supply page for the RTX 5070 has the size with other processors.

How this is worked out

Each part gets one figure for games from the reference dataset the Bottleneck app uses to judge the hardware it measures, and the two are compared at each resolution. The calculator explains the model; this page is its answer for the Core i5-14400 and the RTX 5070. It is an estimate from the part names: memory speed, settings, heat and the monitor decide what a real PC delivers.
