The 5 Best Graphics Card for i9 13900K Reviews

Reasons to Buy

  • Brilliant performance.
  • Great thermals and acoustics (at least in stock settings).

Reasons Not to Buy

  • Huge: requires a large case.
  • Extremely expensive.

The RTX 4090 ASUS ROG is based on Nvidia’s latest Ada Lovelace architecture and is the fastest graphics card you can buy today. Almost everything with this card is pushed to the limit, be it the size, memory, performance, or power consumption, you name it. It measures 358x149x70 mm, so be sure you have a roomy case to house it. Its 24GB VRAM, coupled with 85 TFLOPS floating point operations, means that 4K gaming is a piece of cake for this monster.

The card’s stock TDP of 450W, when coupled with the i9-13900K’s 125-253W TDP, becomes plain as day that you will require a massive PSU, preferably above 800W. The card has 2X HDMI 2.1 ports and 3X DisplayPort 1.4a, which means that compatibility with most 4K monitors will not be an issue since this card is overkill for 1080 gaming, anyway. However, with the $1600 MSRP ($2000 for our aftermarket card) for the 4090, we are slightly disappointed that Nvidia went with DisplayPort 1.4a instead of the latest 2.0.

To test graphics performance, we ran the brutally demanding CyberPunk 2077 at two settings: 4K and 1440p, with ray tracing, enabled in both of them. We didn’t alter too many settings because this card is supposed to handle whatever we throw in its way like a champ. At 4K, we got an average of 47 fps which is decent considering the game’s reputation for torturing computer hardware. At 1440p, we got 87 fps, which is a brilliant number. Since we kept our card at stock settings, thermals and acoustics remained unnoticeable, so to speak.

So, what do we have to say regarding this card? After all, is said and done, it is the best graphics card you can use alongside the i9-13900K. The only “major” drawbacks we could find with this card are its size and price. For comparison, at $1600, an entire RT-enabled gaming PC can be built. However, not everyone is concerned as much about the best bang for the buck as they are about absolute performance, and it is for those users that we will most strongly recommend this card.


Reasons to Buy

  • Extremely fast.

Reasons Not to Buy

  • Power hungry.
  • Not hugely faster than RTX 3090.
  • Quite expensive.

The MSI GeForce RTX 3090 Ti SUPRIM X is the fastest graphics card you can get your hands on, or at least until the RTX 4090 wrested that title from it. It is based on the Ampere architecture, which immediately precedes Nvidia’s latest Ada Lovelace architecture. Like most ultrahigh-end graphics cards, this one is massive at ~2kg and takes up considerable space. So, you might be better off investing in a large PC case.

The Suprim X has a power rating of 480W, and MSI recommends a PSU of 850W to couple with this card. It won’t be an exaggeration to say that it is due to the graphics cards like these that desktops are already hitting the kilowatt level in terms of power consumption.

The card features one HDMI 2.1 port and three DisplayPort 1.4a. The HDMI 2.1 can be especially handy to couple your PC with huge 4K, 120 Hz screens for an ultra-immersive gaming experience. Different ports mean you won’t worry much about finding a compatible monitor. However, compatibility is not enough. When you’re paying more than $1500 for a graphics card, it would be a most egregious error to use it alongside a 1080p monitor. At a minimum, go for a 1440p high refresh rate screen or, ideally, a 4K one.

Now, onto our gaming tests. In CyberPunk 2077, the card generated an average of 44 FPS at 4K settings and 83 FPS at 1440p, with raytracing enabled in both tests. So, in terms of gaming, this card performs very close to the latest RTX 4090, at least for this particular game.

So, how likely are we to recommend this card? Although from the lens of absolute performance, this is one of the best cards you can buy for i9-13900K. However, a few single-digit percentage point increases in performance over the RTX 3090 don’t justify a $400 surcharge. Plus, two other reasons make this card a hard sell: the release of the faster RTX 4090 and the already present better value RTX 3080.


Reasons to Buy

  • Great 1440p performance.
  • Excellent bang for the buck.

Reasons Not to Buy

  • None, really.

Coming at an MSRP of, the Gigabyte RTX 3080 is one of the best graphics cards from a value standpoint. The RTX 3080 is based on the Ampere architecture, which is a massive step from the older Turing architecture. It features 10GB GDDR6X memory with a bandwidth of 760 GB/s for extremely fast data transfer rates between the GPU and the rest of the system, resulting in great overall gaming performance.

While this card is smaller than the cards we reviewed earlier, with dimensions at 320x129x55mm, the RTX 3080 will still require a large case for better airflow. You don’t want to ignore this because heat can quickly shrink a graphics card’s shelf life.

The card comes with a TDP of 480W, and according to Gigabyte’s recommendations, you should invest in a 750W PSU to fully use this card without running into system crashing issues. The card comes with two HDMI 2.1 ports and three DisplayPort 1.4a and can support a maximum resolution of 7680x4320, or 8K. However, in real terms, this card will work at the 8K resolution for only relatively lighter titles. For 8K, you should invest in a higher-end and much more expensive RTX 3090.

To test the card’s gaming performance, we played CyberPunk 2077 at ultrahigh settings with ray tracing enabled. However, we did alter the resolution between 4K and 1440p. At 4K, we got an average frame rate of 33 FPS and 57 FPS on 1440p. This is not shocking as the card costs less than half what the earlier reviewed cards do. Even then, ~60FPS at 1440p is more than an excellent gaming experience for most users.

So, what are our final thoughts on the Gigabyte RTX 3080? This is a powerful card with an “entry-level” price (for high-end gaming). Its great combination of value and absolute overall performance makes it the best card for i9-13900K for most users. To put it more bluntly, if you enjoy not getting ripped off in the name of performance, we’d say close your eyes and go with this card for your next PC build.


Reasons to Buy

  • Excellent gaming performance.
  • Can fit in mid-tower cases.

Reasons Not to Buy

  • Awkward pricing.

The ZOTAC RTX 3070 Ti is based on Nvidia’s Ampere architecture and comes with an MSRP of $750. The card features 8 gigs of high-speed GDDR6X memory on a 256-bit bus, alongside a bandwidth of 608Gbps, resulting in support for 8K, 60Hz displays, or up to 4 screens for those who use multiple monitor setups. Don’t forget that you will need an Ultra High-Speed HDMI Cable to view 8K content at 60 fps.

The card is sized at 316.8x122.7x58.6 mm, which means that unlike the cards reviewed earlier, this card will fit in a mid-tower case just fine. It has a slot size of 2.5, which, in practical terms, means blockage of access to 3 PCIe slots, rendering them unusable for connecting something like an SSD. However, this will be fine as most people rarely use the extra slots.

In terms of power consumption, the ZOTAC RTX 3070 Ti comes with a rating of 310W, which though significant, is much lower than its immediate superior, 3080’s 480W, for instance. ZOTAC recommends using a 750W PSU, which is great if one errs on caution. However, a PSU of 650W will also be quite adequate.

The card performs excellently in gaming, provided your expectations are reasonable. At 1440p with RT enabled, the 3070 Ti gave quite an acceptable frame rate of 53 fps (avg) in CyberPunk 2077, while in 4K, the average frame rate hovered around 30 fps, which is a bit too modest, hence the note on expectations.

So, should you buy the ZOTAC RTX 3070 Ti? Based on the card’s specifications and our gaming test alone, we would have gladly termed it one of the best graphics cards for i9-13900K, were it not for the awkward pricing Nvidia went with. For example, its performance increases over the 3070 are minuscule but come at a $100 premium. The 3080, in contrast, actually provides a significant performance jump for the price increase. So, if you are already spending more than $500 on a graphics card, we recommend doing it on a 3080.


Reasons to Buy

  • AMD’s fastest card at the time of its release.

Reasons Not to Buy

  • Expensive.
  • Only slightly faster than 6800 XT.
  • Leagues behind Nvidia in raytracing.

The Sapphire RX 6900XT is the aftermarket variant of AMD’s fastest graphics card at the time of its release and comes with a hefty MSRP of $1000, almost twice as much as the $650 RX 6800XT. We’ll see if this price jump translates into a similar increase in performance. Spoiler alert: it doesn’t. Based on the RDNA 2 architecture, released in the last quarter of 2020, the card features 5120 streaming multiprocessors compared to 4608 in the RX 6900XT, resulting in faster overall performance, but not enough to justify the steep price jump.

The graphics card sports 16 gigs of GDDR6, not GDDR6X, memory with a bandwidth of 1664 Gbps, almost twice as much as that of RTX 3090, but don’t be fooled. Based on its Infinity Cache technology, this is “effective” bandwidth, as AMD likes to call it. Where it matters, gaming, that is, the RTX 3090, still gives better performance.

The 6900XT comes with a power consumption rating of 340W, and Sapphire’s minimum recommended PSU size for this card is 850W. At 310x134.3x55.3 mm, the card is similar in size to the RTX 3070Ti and should be able to fit inside any mid-tower case. Remember that the card will block access to 3 PCIe slots to avoid headaches and is only compatible with ATX motherboards.

Coming towards gaming performance, the card does support ray tracing with its 80 Ray Accelerators. However, raytracing is a field where Nvidia soundly defeats AMD. In Cyberpunk 2077, at 4K with ray tracing disabled, the 6900XT achieved a framerate of 63 fps: pretty decent, we must say. However, the figure fell to less than half at 20 fps when ray tracing was turned on: unplayable. So, if raytracing is important to you, go with Nvidia.

So, to wrap up, should you buy the RX 6900XT? Although this was AMD’s best effort at the time of its release, this card is hard to recommend, mainly due to the minuscule performance gains over the RX 6800XT and worse ray tracing performance compared to its similarly priced rival, the RTX 3080.
