How to Choose the Perfect CPU for GTX 1070?

Intel CPUs or AMD CPUs?

Intel are one of the leaders in processors, and are hightly comptable with most graphics cards on the the market. Not only this, but Intel seem to have better performance and efficiency overall when gaming and mutlitasking.

AMD however, are more budget friendly whilst providing the same, or similar performance of that of Intel. Depending on your motherboard chipset, and your budget to make your gaming PC or workstation, then AMD might be for you.

Clock Speed / Overall Speed

Most CPUs have visable speeds and clock-speeds that you need to take note of when comparing CPUs. The GTX 1070 is an amazing GPU, but you need to have a decent CPU to keep up to avoid bottleneck. Our reccomendation is that you aim to have over 3.2 GHz to run with the GTX 1070, for peak performance.


Cores are physical chips within the CPU, that offer up its power and host the threads. Modern CPUs can come from anywhere between a single-core, to 32 or now even 64-cores, but for most modern gaming PCs, a simple 4-8 Core CPU will be just fine, and last a while.


Threads are the individual processes that a chip can handle at a given time. Intel refers to this with Hyper-threading while AMD calls it Multi-threading.

Many power-demanding programs like video editing, coding, and gaming require more threads to work faster and smoother.



What is the best CPU to pair with a GTX 1070 for gaming?

If you are buying a CPU for gaming to work perfectly with GTX 1070, then you should really consider the Intel i7-8700K. It is one of the best processors for gaming with six cores, 4.7 GHz clock speed, and 12 MB of cache. When combined with the GTX 1070, you’re almost guarenteed to run any games on high-settings with ease.

Why does CPU Matter?

CPUs are one of the few main compnenets that you need to get the most out of your computer. The GTX 1070 is a fairly powerful GPU that you need to have an equally as good CPU for. This means that if you want to get the most out of your GPU, then you need to get an equally, or better CPU.

What’s a good CPU to pair with a GTX 1070 8GB Edition?

As per our guide, the above CPUs are some of the best CPUs that you can tie with the GTX 1070 8GB that means you can run any game with ease, not to mention effortless mutlitasking.

Be sure to make your own decisions, but we hope we can help with the decision!

Are these CPUs Compatible with a GTX 1070 TI as well?

Of course! The GTX 1070 TI is compatable with most CPUs on the market these days. The GTX 1070ti is another GPU that you may want to upscale on your CPU, so for this one – we reccomend either the Intel i7-8700K or AMD Ryzen 7 3800x.
