NVIDIA graphics cards are getting better by a significant margin with each new generation and things are the same with the all-new GeForce RTX 4000-series graphics cards. The power consumption of the graphics cards has highly increased too, and now the TDP of high-end graphics cards is above 300 watts. Overall, the performance improvement in this generation seems to be around 30 to 50% when we compare it with the previous-generation graphics cards. In this article, we will check the best CPU for RTX 4080.

NVIDIA GeForce RTX 4080 is the mainstream high-end graphics card from the RTX 4000 series and there are two RTX 4080 in this generation, one with 12 GB memory and one with a 16 GB memory buffer. The graphics card we are discussing here is the 16 GB variant and it comes with 9728 shader processing units, 304 Texture Mapping Units, and 112 Render Output Units. The clock rates of the graphics card are greatly improved from the previous generation, with the base clock set at 2205 MHz and the boost clock set at 2505 MHz.

The Core i5-12600K was Intel’s first truly effective weapon, leveling the playing field with AMD and outperforming AMD’s Ryzen 5 5600X. The Core i5-12600 K’s suggested maximum retail price is $299, which is also the Ryzen 5 5600X’s market price. For the same price, the Intel Core i5-12600K performs better than the Ryzen 5 5600X, but there’s more to the tale. The initial platform entry cost is much higher with the Intel CPU. You’ll also need a new motherboard, new DDR5 memory, and a new CPU cooler to get the most out of the processor.

This mid-range CPU is based on the “Alder Lake” architecture. The Alder Lake CPUs from Intel are the first to use a hybrid core design for desktop PCs, enabling significant performance increases and improved efficiency. Intel’s Core i5-12600K has a 6+4 design, which means it contains six performance cores (P-cores) and four efficiency cores (E-cores), totaling 10 cores.

The performance cores (P-cores) feature hyperthreading, enabling processing of 16 threads at once. Performance cores can operate up to 4.9 GHz, while efficiency cores can operate up to 3.6 GHz. All cores have access to the 20 MB Smart Cache. The inbuilt memory controller supports up to 128 GB of DDR5 memory at 4800 MT/s (dual channel). Rated at 125-watt base power and 150-watt max turbo power, along with PCIe 5.0 support, and manufactured at 10nm. The 10nm node from Intel is a process technique that relies on a 13-layer metallization stack and FinFET transistors.

Taking everything into account, it’s no mystery why the Core i5-12600K is compatible with a highly demanding GPU such as the Nvidia RTX 4080. What’s truly remarkable about the Core i5-12600K is its awesome specifications at such an affordable price.

When buying the Best Motherboard for i5 12600K, there are many options, but spending hundreds of dollars on a mid-range processor doesn’t make any sense. So we’ve made this easy for our users with a dedicated guide on this topic.


Some of the best CPUs that money can buy now are AMD’s new Ryzen 7000 models. It shouldn’t be a surprise that the new AMD Ryzen 9 7900x performs better than any of Intel’s earlier-generation CPUs, given that these processors are AMD’s response to Intel’s 12th-generation processors. To enable these processors, AMD is also launching an entirely new platform called AM5. Even though this implies a new motherboard is needed for these processors, which may seem like a hassle, AMD has vowed to support AM5 through at least 2025. With AM5, you’ll be able to update your CPU over time without buying a new motherboard, much like the previous AM4, which lasted for five years and five generations.

Regarding specs, AMD Ryzen 9 7900x performs noticeably better than Intel Core i9 12900k. Amazingly, the new AMD CPU boasts a 4.7 GHz base clock and a 5.6 GHz turbo boost frequency. The processor only has 12 physical cores, but it makes up for it with 128 GB of DDR5-5200 memory, 64 MB of shared L-3 cache, 24 total threads, and a cutting-edge 5 nm manufacturing process. In addition to everything else, AM5 provides longer support than Intel’s LGA 1700. Its GPU boost rate of 2200 MHz further enhances its appeal as a processor.

The AMD Ryzen 9 7900x is one of the most potent, cutting-edge, and reasonably priced CPUs currently on the market, and it works especially well with the Nvidia RTX 4080. This contemporary processor allows users to overclock and readily satisfy all demanding Nvidia RTX 4080 specifications. This combination is among the greatest choices available for someone who needs a computer that operates incredibly quickly and is capable of playing video games at an incredible but reliable frame rate.


AMD released the Ryzen 7 5800X3D in April 2022. This chip was the first to introduce 3D V-caching technology to the world. The 5800X3D processor highlighted how much of a difference a change in caching technology can make by outperforming Intel’s flagship model, the Core i9 12900K, solely in terms of gaming performance. Only slightly quicker than this CPU are the Ryzen 9 7900X and 7950X; however, they only offer comparative gains of around 2% across various AAA games. However, unlike every other Ryzen processor, the 3D V-caching-capable Ryzen 7 is a locked chip. Overclocking the core is, therefore, not possible, but memory may be overclocked.

The improved and affordable Ryzen 7 processor is based on the last-generation Zen 3 architecture. Similar to the Ryzen 7 5800X, it has 8 cores and 16 threads. The processor’s base rate is 3.4 GHz, while its boost clock may reach a maximum of 4.5 GHz. It includes a massive 96 MB L3 and 4 MB L2 cache. The chip also has a low 105 W TDP. Additionally, this CPU uses 128 GB of DDR4 memory, which may slightly hinder its production potential, but it also keeps the cost low.

The Ryzen 7 5800X3D is a gaming-focused processor. Users might choose this processor if their machine’s primary purpose is to run video games speedily. Users will, however, be better off with other AMD or Intel chips if their gaming setup also serves as a workstation. Nevertheless, users won’t be dissatisfied if they want to run CPU-intensive programs as the Ryzen 7 5800X3D still has a respectable amount of productivity potential. As a result, it pairs perfectly with the powerful Nvidia RTX 4080, and purely in terms of game performance, the pairing of AMD Ryzen 7 5800X3D and Nvidia RTX 4080 is possibly the best one currently available.


AMD’s first CPU with the Zen 4 architecture is the Ryzen 5 7600X. On the bottom of the Zen 4 7000 series lies the Ryzen 5 7600X, which is still a powerhouse. The 7600X is made for gamers on a budget who want unmatched performance and raw power at a cost they can afford. Making a reasonably priced, dependable processor like the Ryzen 5 7600x has the goal of regaining some market control that was lost following the release of Intel’s 12th Gen CPUs. AMD believes its new Zen 4 architecture will help bring them success.

The Ryzen 5 7600X is a 6-core, 12-thread processor built on a single 5nm manufacturing process. It supports DDR5 and has a 105W TDP. It also boasts a base clock speed of 4.7 GHz and a boost speed of 5.3 GHz. While 6-core is far from optimum, the price makes this chip worth buying. Additionally, because it is made for the new AM5 socket, customers must upgrade their motherboards before installing this chip. This has the advantage of AMD guaranteeing AM5 support until 2025. Compared to Zen 3, new Zen 4 CPUs boost peak clock speeds, improve IPC, and almost double the L2 cache capacity.

The Ryzen 7000 Series' availability of integrated graphics across the board is the most notable feature upgrade. As a result, the 7600X is not an APU but a CPU with adequate graphics to perform all the tasks which the most expensive CPUs can also carry out. While the Ryzen 5 7600X is a powerful and quick CPU, it is not the most powerful or quickest currently on the market. It does, however, claim the additional advantage of being reasonably priced. Businesses that don’t require discrete GPUs but still need the processing power will find the Ryzen 7000 Series more appealing. If the user’s focus user focuses on gaming, then pairing this powerful CPU with the NVIDIA RTX 4080 won’t disappoint you at all.
