AMD Ryzen 9 7900X AMD has made notable enhancements to single-core performance, placing it on par with Intel's previous-generation Alder Lake CPUs. This makes the 7900X a great choice for 4k gaming. The Ryzen Zen 4 CPU cores now boast double the cache, with each core having 1MB instead of the previous 512KB.
Windows devices requirements for 4K recording:
Intel i5 or i7 (Broadwell or newer) processor. Screen resolution of 1920×1080 or higher. CPU benchmark: 6000 or higher.
But what you really want is a good CPU with very fast single core speeds like the i3–12100F. Or really any quad core that hits 4GHz. 4K gaming will almost always be GPU bound and feature relatively low frame rates that any CPU can handle with ease. 4GHz Quad cores are good to about 140fps before the start to drop off.
For 4K gaming the CPU doesn't really matter. You can get by with an old 1000 series Ryzen on a RTX 3090 and you would still not really run into problems. It's when you drop the resolutions down below what the graphics card can handle when you start to push the game to become more CPU bound.
The recommended number of cores for a proper gaming experience would be six cores or higher. If you want to future-proof your setup and your PC can take advantage of it, you could use a CPU with eight cores.
It features the latest NVIDIA architecture and offers impressive performance for its price range. With its 12 GB of GDDR6 memory and 3584 CUDA cores, the RTX 3060 can easily handle demanding games and applications. Without a doubt, the RTX 3060 can run games at 4k, with a medium graphics setting.
Required PC hardware
The most important thing is the video card. For an optimal 4K experience, only the best cards are suitable. Think about the GTX 1080 Ti, and RTX 2080 Super, or at least an RTX 3080. Without this video card, gaming in 4K is difficult, even with a suitable monitor.
At lower resolutions there are less pixels to render, so there is less of a workload that the GPU needs to deal with. At a 4K resolution, the opposite is in effect. 4K games place a higher intensity workloads on the graphics card, and therefore the CPU has less to deal with overall.
For a 2160p image signal, your 4k screen and your PC or laptop should have DisplayPort, HDMI, Thunderbolt 3, or USB-C. Old connectors like VGA and DVI connectors don't support 4K. DisplayPort 1.2, HDMI 2.0, Thunderbolt 3, and some USB-C connectors support 4K at 60 frames per second.
Generally at 4K, GPU is most 'important'. 4K rendering require a great GPU something like RTX 3080. CPU is 'least' important when gaming at 4K.
You need a powerful graphics card to run cutting-edge PC games at 4K resolution. These high-end GPUs are the top performers we've tested for pixel-packed gaming.
How much RAM do I need for 4K gaming? The minimum you need for 4K graphics is 8 GB, but 16 GB is recommended. Most modern graphics cards are capable of 4K. You also need a 4K monitor.
Every GPU will be different, but the vast majority of 4K capable cards will likely need 750W as a minimum.
Equally as important is RAM, but how much is enough? A minimum of 16 GB of RAM for HD is fine, but with 4K or 6K editing, that minimum rises to 32 GB or more. Data must be quickly accessible to both the CPU and RAM so storage speed is crucial.
If the display supports 4K, a green check mark will appear and the message underneath 4K Display will read "Your display is a 4k-capable high definition display (4x more pixels than HD)".
It depends on you
So, should you buy a 4K monitor for your gaming PC? It really depends on what you want to use it for. If you're going to be playing single-player games with expansive vistas or doing high-end video work and you have a powerful graphics card to run it all, then go right ahead.
First, right-click the Windows desktop and choose Display Settings. Set Display Resolution to 3,840 by 2,160 (it should say "Recommended" in parentheses next to it). This will ensure your PC is outputting a 4K signal. Now, launch a game and enter its display settings.
The most likely reason why 4k uses less cpu than 1080p is that the fps is lower. Less fps = less number of times per second that the cpu has to produce a frame.
because 4K is a very high resolution and demands high performance computer, especially when gaming! You might have a standard PC with cool “normal” components and use a 4K monitor or 4K TV as your image output device.
In conclusion, the CPU choice for an RTX 3090 GPU setup is crucial for optimizing its performance. The Ryzen 9 5950X and Intel Core i9-12900K are the best options for content creation and the Ryzen 7 5800X3D is the best for gaming.
While this refresh rate isn't as high as other gaming monitors with lower resolutions, most modern gaming PCs struggle to maintain high frame rates with a 4k resolution anyways, which is why 4k 144Hz monitors are great choices for most gamers.
The top CPU and GPU for high-end, VR, and 4K gaming
Ray tracing can really make a game's visuals pop, but it can add a lot of extra strain to the GPU. Recommended Hardware: CPU: 13th-gen Intel Core i5; AMD Ryzen 5 7000 series. GPU: Nvidia GeForce RTX 4070, AMD Radeon RX 7800.
Gaming on a 4K monitor with a refresh rate of 144Hz is the epitome of gaming excellence. It blends high pixel resolution and rapid refresh rates to create an immersive and seamless gaming experience.
So, in conclusion, if you want great 4K 60 fps gaming, the 3080 Ti is good for you. However, if it's the 144 fps barrier you want to hit, you'll be better off with the last get 4000-series for your rig.
The RTX 3080 model is one of the best gaming cards for 4k gaming. It offers a high-resolution gaming experience with its DLSS and ray tracing features, even at high frame rates. It is a future-proof card that works well for present-day and upcoming games.
