You might’ve expected the RTX 3070 or the RX 7700 XT to be at the top of the list, but during our hands-on review of the RTX 4070, we found that it performed exceptionally well for a mid-range card.

First, this GPU has a base clock speed of 1.92 GHz and a turbo clock speed of 2.48 GHz. While these clock speeds might not seem impressive on paper, you should know that GPUs mainly focus on processing large amounts of data simultaneously. So, these clock speeds should be more than enough to deliver stellar gaming performance, and you can always set it to its highest settings for more snappier performance.

It features 5,888 CUDA cores, which are also responsible for its ability to handle and process large data sets in parallel without sacrificing performance. It also features 67 Teraflops (TFLOPS) of Ray Tracing cores, which transform your in-game graphics into serene visuals and enhance your gaming experience. So, with this GPU powering your graphics, you should get a seamless experience and stable framerates.

Regarding its VRAM, it sports 12 GB of GDDR6X memory with a 192-bit memory interface. The memory interface is responsible for the amount of data that can travel any moment. So, the greater the memory interface width, the better and faster the performance. On top of that, the 12 GB VRAM should allow you to tweak in-game settings or use ultra presets without burdening the memory. So, these two aspects should complement each other and deliver good performance.

As far as connectivity is concerned, this graphic card has two HDMI ports and three display ports. What this means is that you have enough options to connect multiple monitors for a multi-monitor setup. On top of that, this GPU supports a maximum resolution of 4K at 240 Hz and 8K at Hz. That said, running two or more monitors with full resolution and a 240 Hz refresh rate won’t be possible for a single GPU.

According to Nvidia, this GPU’s idle and average power draws are 10W and 186W, respectively. However, these numbers can fluctuate depending on the workload, especially if you’ve overclocked your GPU. In that case, it’s recommended to have an adequately ventilated case, and we’ve got you covered with our best airflow PC case guide.

Lastly, this GPU has the latest DLSS 3.5, which should help boost in-game frame rates by using AI to render and upscale them to the appropriate resolution. And regarding raw performance, the RTX 4070 performed 3.5 times better than the RTX 3070 Ti in titles like Cyberpunk 2077, with DLSS and Ray Tracing maxed out at overdrive.

While newer releases like the RTX 4070 Super might overshadow the base model, it doesn’t knock it out of the race. Given its performance and benchmarks, we think it’s one of the best GPUs for i5-12600K.

You can expect a 4070 to achieve 1440p gaming easily. It may not achieve 4k in the latest games, but it will with older titles

If you’re looking for the best AMD GPU for i5-12600K, we recommend you check out the RX 7700 XT. In our RX 7700 XT review, we found that it performs well at 1440p, and on top of that, it costs less than our top pick.

For starters, this GPU has 3,456 stream processors, which are AMD’s equivalent of CUDA cores. However, they are directly relatable in performance as both have their unique architecture and way of processing information. That said, these stream processes combined with its base frequency of 2,171 MHz and boost frequency of 2,544 MHz should result in top-notch 1080p and 1440p gaming at high and ultra presets

It features 12 GB of GDDR6 memory with a 192-bit memory interface. This specification is almost the same as the RTX 4070, with the difference being the memory type. That said, this GPU has the AMD Infinity Cache technology. This is a specialized L3 cache that is visible for the complete graphics core. It stores frequently accessed and needed data directly onto the high-speed GPU memory. This means that the GPU doesn’t have to go through the usual system checks and can retrieve, process, and deliver the output much quicker.

This technology should significantly boost your system’s overall graphic capabilities and help render games faster. On top of that, it features the AMD FidelityFX Super Resolution (FSR). This deal with Ray Tracing in AMD GPUs, and while Team Green has the lead in this domain, Team Red is making significant progress, and the results aren’t something you can put aside. So, if single-player gaming with ray tracing on is something you’re interested in, this GPU has you covered.

According to AMD, with FSR 3 performance mode and Frame Generation turned on, you should go from 33 FPS to 103 FPS in titles like Forspoken at 4K resolution. This massive increase in performance shows that DLSS isn’t the only contender in the market. However, Frame Generation depends on what GPU you have, if you’re running the supported titles, and whether you’re hitting 60 FPS for Frame Generation to kick in.

While this graphic card can handle 4K gaming, that is most likely not the case for every title. That said, the RX 7700 XT shines at 1440p. Here are the results for some titles at 1440p and max settings, as claimed by AMD.

If you’re working with a more limited budget for modern gaming and don’t want to miss out then the AMD Radeon RX 7700 XT could be just what you’ve been waiting for.

If you’re looking for the best Nvidia GPU for i5-12600K, check out the RTX 3080. The shift from the 4000 series to the 3000 series might come as a surprise, but given its performance and price bracket, the RTX 3080 is still a strong contender. In our RTX 3080 review, we saw that it made quick work of titles like Doom Eternal and Fortnite at 1080p, 1440p, and 4K.

For starters, this GPU comes in 10 and 12 GB variants, and both have the same boost clock of 1.71 GHz. The difference is in the base clock speed, which is 1.26 and 1.44 GHz, respectively. What this means is that depending on the version you choose, you’d get more or less performance, but generally, the 12 GB version is preferred due to the obvious increase in performance.

In addition, the 12 GB version has 256 more CUDA cores, 8,960, compared to the 10 GB variant’s 8,704. CUDA cores are responsible for handling a large amount of data that needs to be processed in parallel. So, the more cores there are, the better and faster the performance will be.

Both variants have GDDR6X memory, which should also contribute to the top-notch performance when paired with the i5-12600K. However, the 12 GB variant has a 384-bit memory interface width compared to the 10 GB’s 320-bit. The higher memory interface means more data can travel comfortably, which means less bottleneck risk and better performance.

According to Nvidia, at 4K with the highest game settings, the RTX 3080 had close to 100 FPS in Control while the RTX 2080 struggled to cross 60 FPS. However, this doesn’t mean that you’ll see similar performance across all titles, and you most likely will have to tweak some in-game and DLSS settings.

That said, since all RTX cards can use DLSS 3.5, the performance should be decent at 4K, but for QHD gaming, this card is an absolute powerhouse and should easily blow through various titles. However, one thing to remember is that its market value might dip since the 50 series is rumored to be released later this year.

All in all, despite being a last-generation card, the RTX 3080 is still making waves in benchmarks and is still widely being used. For a CPU like the i5-12600K, this GPU is one of the best options, especially if you plan on gaming at 1440p and want to keep costs under check.

How to pick the best GPU for i5-12600K

Selecting a GPU for any processor sounds like a simple task, but a handful of factors come into play, and ones you need to consider before making a decision. Spending your money on the most decked-out options isn’t wise, as unless you have an enthusiast build, you won’t need all that firepower. So, to help you make an informed decision, we’ve listed some of the factors below.


The first thing you need to consider is your budget and the options available to you. The i5-12600K isn’t a high-end option, so spending top dollar on a GPU that costs double its price doesn’t make sense. So, opt for a GPU that complements this CPU and falls under a relative price range even if it’s not part of the latest generation.

Your requirements

The GPU that works best for you depends on what you want to use it for. For example, if 1440p gaming is something you plan on doing, an RTX 3080, 3070 Ti, or even an RTX 4060 might cut it for you. However, if 4K gaming, heavy rendering, editing, and training are part of your plan, then going for a high-end option such as the RTX 4090, which we also have an in-depth review of, might be the option for you.


Putting time into watching videos and reading through reviews is a good way of understanding how a GPU you’re leaning toward will perform with your setup. There are plenty of sources out there, and you can find setups like your own, which is the best-case scenario. However, even if a couple of components are different, the performance shouldn’t vary much and give you a good idea of what you can expect.

Power consumption and cooling

The stronger a graphic card is, the more power it’ll require to perform optimally. If you get your hands on a high-end GPU, it’ll consume more power, which can affect costs in the long term and generate more heat. To dissipate that heat and keep your GPU from throttling, you’ll need to get a variant with triple fans or a suitable casing with powerful case fans.

In some GPUs, there is also the option to switch directly between performance and quiet mode. The quiet mode controls the clock speeds, meaning the GPU is relatively cool and doesn’t draw more power.

However, in performance mode, the clock and fan speed are ramped up to keep the temperature under control while delivering the best performance. So, depending on your ambient temperature and current casing, the GPU you opt for and its design might impact the overall performance.

What is the minimum PSU for i5-12600K?

The minimum PSU requirement depends on your overall build. If you have powerful components or parts that are overclocked, they’ll draw more power and will require a PSU with a high capacity. For example, if you pair an i5-12600K with an RTX 3080, then a 650-750W PSU would be recommended just to be on the safe side.

What RAM is compatible with i5 12600K?

According to the i5 12600K’s product specification page, it is compatible with both DDR4 and DDR5 RAM as it supports the PCI Express standard 4.0 and 5.0. However, there is an upper limit, as pairing with a maximum of 1600 MHz DDR4 and 2400 MHz DDR5 RAM is recommended.

Our Verdict

After considering the price, performance, and features the listed GPUs bring to the table, we concluded that the best GPU for the Core i5-12500K is the RTX 4070. Coming in the mid-range category of the 40 series Nvidia GPUs, it has all the latest tools in its arsenal, a more efficient power draw, and a performance output that complements the i5-12600K.
