CPU and GPU pairings

Does the Core i7-8700K bottleneck the RTX 3060?

At 1080p, the two are well matched. At 1440p, the graphics card sets the pace. At 4K, the graphics card sets the pace, by a wide margin.

Intel Core i7-8700K with NVIDIA GeForce RTX 3060

  1. 1080p

    Well matched

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

  2. 1440p

    The graphics card sets the pace

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

  3. 4K

    The graphics card sets the pace, by a wide margin

    The processor could keep up with a graphics card about 2.2 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.

  • The RTX 3060 is sold with 8 GB or 12 GB of graphics memory. With 8 GB, some recent games need their texture quality lowered at 1440p and 4K, and a few at 1080p. Stutter and textures loading late are the sign.

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:

  • The monitor’s refresh rate. A 144 Hz monitor left at 60 Hz holds every game to 60 frames a second.
  • Memory at its rated speed, in dual channel. Memory left at a slow default speed costs frames whichever part sets the pace.
  • Heat. A processor or graphics card that slows down to stay cool falls short of these figures.

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.

Power supply

A 450 W power supply covers this pair: at full load the Core i7-8700K, the RTX 3060 and the rest of the PC can draw up to about 349 W. The power supply page for the RTX 3060 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 i7-8700K and the RTX 3060. It is an estimate from the part names: memory speed, settings, heat and the monitor decide what a real PC delivers.
