Currently, there are dozens of CPUs with different core speeds but priced differently; however, not all of them will deliver the value you seek. Some of the best CPUs can reach top speeds of 5.3 GHz on 10 cores with single-threaded performance, but they cost a lot!
So, if you are looking for an affordable but efficient CPU, you can still find one in your budget. This short review is essentially for buyers who cannot afford the super-fast but expensive CPUs.
The three CPUs we selected below were based on affordability, efficiency, and 3080/3090 RTX compatibility. Let’s find the CPU that complements the RTX 3080 or 3090 perfectly.
Please read our review and let us know what you think.
1. AMD Ryzen 9 5900X 24 Thread 12-Core Desktop Processor
Best Budget-Friendly CPU
· Model – AMD Ryzen 9
· Number of Cores – 12
· Socket – AM4
· Threads -24
· Base Speed – 3.8GHz
· Boost Speed – 4.6GHz
· Total Cache – 64MB
· TDP – 105W
AMD Ryzen 9 is a powerful processor and one of the best budget-friendly CPUs you will ever lay your hands on. It is designed to help you with peak performance and speed for your computing. Boasting a base speed of 3.8 GHz and a boost clock speed of 4.6 GHz, this processor has all you need to complete the most demanding tasks in less time. If your former CPU broke down under extreme workload, you would not have such a problem with Ryzen 9.
One feature we like is its pristine Zen 2 architecture and 7nm processor, which has more transistors. Also, the infinity Fabric makes communication between the GPU and CPU faster and more efficient
Might we also add that AMD Ryzen 9 does not overheat due to its Wraith internal Prism cooler, which keeps the processor in stable condition and prevent thermal throttling. The price tag represents value for money if you are looking for a CPU that will not let you down.
2. Intel Core i9 – 12900K 16 (8P+ 8E) Desktop Processor
Best Peak Performance CPU For RTX 3080 and 3090
· Model – Intel Core i9
· Cores – 16
· Performance Cores – 8
· Threads – 24
· Turbo Frequency – 5.20 GHz
· Total Cache – 30 MB Intel
· Turbo Power – 241 W
· Base Power – 125 W
If you have the cash to burn, we recommend the Intel Core i9. This CPU processor is highly rated, and reviewers consider it the best desktop processor ever made. Are you a content creator, a gamer, or an overclocker? This is an ideal desktop processor that can handle demanding tasks.
Never again will your workflow be impeded by slow speed or system glitches. Intel Core i9 boats a case speed of 3.5 GHz and an ultra-powerful turbo boost of 5.2 GHz, which is more than enough power for a heavy workload.
Furthermore, the i9 has large internal storage for large files, so you may not need an external drive to save your materials. Despite its expensive price, this is one CPU that will serve you for several years, so it has a Hugh economic value. It has the new Z490 chipset that supports PCIe 4.0. Gamers will love the speed and power of this machine. It is one of the top choices for power users too.
3. Intel Core i7 -10700K 8 Cores Desktop Processor
Best for RTX 3090
Model – Core i7
Threads – 16
Cores – 8
Base Speed – 3.8 GHz
Boost Speed – 5.1 GHz
Total Cache – 16MB Intel
TDP – 125 W
Bus Speed – 8 GT/s
The third CPU on our list that will be a perfect fit for your RTX 3090 is the Intel Core i7. Although it will work for RTX 3080, too, we love how it blends seamlessly with RTX 3090 models. It has 16 threads and 8 Cores with a boost speed of 5.1 GHZ and a base speed of 3.8 GHz. You will not have to deal with loaded caches every now and then since it has a 16 MB cache memory that will take some time to fill up. Intel Core i7 can deal with the most demanding application for work and play.
Released under the banner of Intel’s LGA 1200 series, it has a 10th generation Comet Lake architecture; this makes it compatible with current motherboard models.
Core i7 can match the performance of Core i9; the only slight difference i9 has over it is that you might need to update your motherboard from BIOS so it can support a 10 Gen processor. This is the ideal CPU we recommend for professional gamers. Also, note that Core i7 is compatible with all Intel 400 series sockets and chipsets.
These CPUs are some of the best pairs for RTX 3080 and RTX 3090. Although they will cost you a bit of money, the speed and power you will get from any of them will be worth the investment.
