Core i7-8086K bottleneck & gaming FPS

Ranked 149 of 201 desktop processors for gaming in our database (26th percentile). It can sustain roughly 96 fps in a typical AAA title regardless of resolution — that ceiling is what decides whether a graphics card is worth pairing with it.

The frame rate this chip could sustain with an infinitely fast graphics card. It is almost the same at every resolution, because rendering more pixels gives the processor no extra work.

Ranked by how little performance the pairing wastes. Anything much faster than the top entry will sit partly idle at this resolution — though it may still be worth it if you plan to move to 1440p or 4K.

Living with a Core i7-8086K

This processor sits in the lower part of the range and will be the limiting component in most modern pairings. Frame rates will be capped by the chip well before the graphics card runs out of capacity, and no graphics upgrade will change that.

If frame rates are the problem, this is where the money goes. Raising the resolution will not help here in the way it does for a graphics-limited system.

A small cache holds this chip back

12 MB of L3 is modest by current standards, and it costs this chip more in games than its clock speed suggests. Game engines walk large, scattered data structures, so a small cache means more trips to main memory and more stalls on the render thread. Memory speed and timings matter unusually much on a part like this.

A note on age

Released in 2018, this chip is 8 years old. Beyond raw speed it is on an older platform, which usually means slower memory, fewer PCIe lanes and no path to a newer processor without replacing the motherboard. Factor that into any upgrade maths — the chip may not be the only thing you end up replacing.
