Top Rated Processors To Pair With 3070 2023: Reviews
1. AMD Ryzen 9 5900X 12-core, 24-Thread Unlocked Desktop Processor
Touted as the world’s best gaming processor, AMD’s flagship CPU, the AMD Ryzen 9 5900X, is based on AMD Zen 3 Core Architecture.
The CPU was released in 2020 and comes with 12 cores and 24 threads. It is a very powerful CPU that is guaranteed to deliver high-end gaming performance.
And even as the gap between AMD and Intel keeps getting smaller, the Ryzen 9 5900X gives the Intel CPU a performance gap of 30fps at 4K and 75 fps at 1080p.
As such, when it comes to high-end gaming, the Ryzen 9 5900X tops and is also the best when it comes to delivering on both single-core and multi-core performances. In terms of thermal potential, this chip has a slightly low heat tolerance at 71 degrees celsius.
The Ryzen 9 5900X has a TDP of 105W, and a maximum supported memory of 128 GB. The CPU has a base clock speed of 3.8 GHz that can be overclocked to 4.9GHz.
In contrast to its processors, AMD’s switch to 7nm silicon for this processor has allowed for an increase in cache size to 64 MB. This is highly advantageous for two reasons. One is that it will enable faster performance when shooting high frame rates in 1080p games, and second, it allows the CPU to be more energy efficient.
- Energy-efficient as it has a lower TDP as compared to Intel CPUs
- Better gaming performance
- Compatible with the AM4 socket
- It lacks a bundled cooler
2. AMD Ryzen 5 5600X CPU Processor
AMD Ryzen 5 5600X is AMD’s fastest 6-core/12-thread processor based on AMD Zen 3 architecture that can deliver elite 100+ FPS performance in most high-definition games.
This mid-range processor is excellent for games that are not very draining but still heavy on the standard processors.
It is the most used AMD processor from the AMD Ryzen 5000 series due, in part, to its low TDP value of 65W, a base clock speed of 3.7 GHz, maximum overclocked speed of 4.6 GHz, and the presence of the quiet yet capable AMD Wraith Stealth Cooling system. Other finer improvements from its predecessors include a greatly optimized boosting algorithm, better memory overclocking capacity, and a remodeled cache topology.
The system memory support still lags in relation to its competitors as it uses DDR4 memory support at 3200 GHz.
Based on its low pricing, high popularity, and excellent performance, the AMD Ryzen 5 5600X is arguably the best fair-priced CPU for the RTX 3070- it even outperforms the higher-priced Intel Core i9-10900K in 1080 gaming.
- Strong gaming performance
- Excellent on both single- and multi-threaded tasks
- PCIe Gen4 support present
- Very power efficient
- Presence of a Wraith Stealth cooling system
- Great value-for-money
- Lack integrated graphics
- Lacks a DDR6 system memory
3. Intel Core i9-10900K Desktop Processor
Best rated Intel CPU for Nvidia RTX 3070
Arguably one of Intel’s best performing high-end CPUs, the Intel Core i9-10900K is equipped with ten high-performance cores coupled with 20 processing threads and a 20MB Intel smart cache for unparalleled processor performance.
Intel provided this CPU with an amazing clock speed of 3.7 GHz that can be overclocked to a maximum of 5.3 GHz for single-core tasks and 4.9 GHz for all-cores tasks to smoothen its performance.
These high clock speeds coupled with the processor’s ten cores allow a computer to develop a hyper-realistic gaming experience without overloading the CPU. Given that the standard TDP rating for most CPUs is 150 watts or higher, the Intel Core-i9-10900k comes across as very energy efficient due to its TDP rating of 125W.
However, a huge drawback to this CPU is that it produces massive amounts of heat when all the ten cores are pushed to 5.2 GHz. It is quite scary and necessitates the acquisition of high-end cooling systems to relieve the CPU of some heat. Intel knew this would happen and equipped the Intel Core i9-10900k with a Thermal Velocity Boost feature.
A downside with the Thermal Velocity Boost feature is that it takes only the high-end cooling systems to dissipate the heat seamlessly; otherwise, you should expect short bursts until the threshold is attained.
- Amazing overclocking capabilities
- Excellent gaming CPU
- Intel Optane memory support
- High-end all-core base speeds
- Superior multitasking capabilities
- High energy consumption
- The package does not include any CPU cooler
4. Intel Core i9-9900K Processor
Best Value CPU for RTX 3070
Touted as the fastest gaming processor in 2019, the Intel Core i9-9900K still outperforms many of its competitors in 2023.
And even as Intel tries to catch up with AMD with regards to gaming technology, its adoption of previously discarded Solder Thermal Interface Material (STIM) between the heat spreader and the die for the Intel Core i9-9900K is a huge plus for the company.
This little piece of tech allowed Intel to pack in more cores at higher clock speeds than before.
At a mid-range price, this 8-core/16-thread processor has a base clock speed of 3.60 GHz which can be overclocked to a max clock speed of 5.00 GHz. On the brighter side, it is one of the more energy-efficient CPUs with a TDP of 95W.
The processor was manufactured on Intel’s 14nm++ node, including a UHD 630 integrated graphics engine, boost support for dual DDR4-2666 memory, and easy overclocking due to sport unlocked ratio multipliers. The processor also comes with memory capacity support of 128 GB and 4K support at 60Hz.
Currently, it is still a very good processor that can hold up to some of the higher-priced competitors in the market.
- Excellent gaming performance
- Solder Thermal Interface Material (TIM)
- Intel Optane technology
- Awesome for multi-threaded applications
- High power consumption under heavy load
- Lacks an ECC memory support
