Although we are living in a time where multi-core CPUs are ruling the PC market, most applications and games still depend upon single-core performance. From music production, photo & video editing, to playing AAA games on your computer, every task needs you to have a CPU with faster per-core performance.
Most computing tasks rely on the clock speed of the individual core. And if your CPU comes with a higher clock speed, you can accomplish that task in less time. Intel CPUs are highly rated for their per-core performance as compared to AMD CPUs.
However, in the past few years, AMD has managed to produce chips that are faster in single and multi-core performance. In this guide, we’ll compare CPUs from both Intel and AMD with default higher clock speeds on each core.
List of the Best CPUs with Single Core/Thread Performance
Here are the top-rated processors to consider:
Intel Core i9 9900K – Overall Best Individual-Core Performance Processor

- Ideal for gaming
The Core i7 10700K gets a little more edge in performance over the Core i9 9900K due to its 3.8 GHz clock speed. This processor hits close enough to a Core i9 10900K in average frame rates when playing demanding games. The Core i9 10900K takes lead over this CPU with its two additional cores and higher clock speed.
But when we compare the Core i7 10700K with a Core i9 9900K, there is a significant difference in performance. The i7 10700K manages to score 3081 in single-core/thread performance. And definitely, it’s due to more clock speed that it holds over the Core i9 9900K.
Also, this processor goes 1 on 1 with the high-performing chips in the AMD’s Ryzen 9 Series. Especially, when you render audio and video files, the Intel i7 10700K beats most Ryzen 9 chips.
At the moment, Ryzen processors are cheaper and beat Intel CPUs in overall performance. However, when it comes to a higher clock on a single core, Intel wins the race. And if you are a gamer, you need higher clock speed on each core to hit higher fps, not the number of cores. This is the reason why most PC gamers still prefer Kaby Lake CPUs for gaming.
Upgrading from a Core i9 9900K to a Core i7 10700K won’t let you feel much of a difference. However, if you are upgrading from a CPU like Core i5 6500 to a Core i7 10700K, you can expect a huge performance gain in fps and single-threaded applications.
Playing games like DOTA 2 & PUBG raises the temperature of this CPU up to 60 Degrees Celsius, this shows that Core i7 10700K is capable of handling many demanding AAA titles even if you don’t overclock it.
Core i7 10700K gives you the most bang for your buck in single-threaded workloads. The only thing that you should care about is the motherboard. The LGA 1200 socket motherboards are expensive as compared to LGA 1151 mobos. Therefore, you should have to throw away your older LGA 1151 motherboard if you plan to buy this CPU.
Intel Core i5-11400F – Best Low Budget Processor for Single-Threaded Workloads
Base Clock Speed: 2.6 GHz | Boost Clock Speed: 4.4 GHz | Cores/Threads: 6/12 | Socket: LGA 1200
Reasons to Buy:
- Ideal performance at a fairly low cost
- Compatible with Intel 400 and 500 chipsets
- Low TDP (65W)
The 11th Gen Intel Core i5-11400F is a processor that is ideally designed for achieving higher frame rates and lower latency in demanding AAA games. Although it comes with a 2.6 GHz clock speed out of the box and cannot be overclocked like a Core i9 9900K, it wins at single-core performance.
In single-thread CPU benchmark tests, the Core i5-11400F scores 3063 and beats the Core i9 9900K. The i9 9900K despite having a base clock speed of 3.6 GHz loses the single-core performance battle against the Core i5-10400F.
All of the credit goes to Intel’s latest architecture and Turbo Boost Technology 2.0 that efficiently clocks each core up to 4.4 GHz under heavy load.
Moreover, by spending less you get a CPU that is capable of performing better than high-end CPUs with more cores and clock speeds. If you are tight on budget and need a CPU that can easily render photos, videos, and let you play entry-level to mid-range titles, this is for you.
Although this CPU is fairly priced, the motherboard that it needs (LGA 1200) comes at a higher cost. However, you can find a good deal for an LGA 1200 motherboard on Amazon or eBay.
