How We Test

From PC cases to graphics cards, we like to get hands-on with everything we recommend. Testing the products is a huge part of our overall selection process and it is the best way to ensure we find the best GPUs.

Graphics cards must pass our testing, which is mostly gaming, with some other synthetic benchmarking too. When it comes to an RX 6900XT, we are going to be looking at game performance, thermal performance, and value. Our process helps us paint a more accurate picture of which is actually the best and will help you ultimately make the correct buying decision.

Things To Consider

When it comes to buying any type of tech, especially something like a GPU, there are many key areas that you need to consider before making that final purchase. With the RX 6900 XT being part of AMD’s latest graphics card lineup you aren’t going to be disappointed but we still need to ensure it’s the best card for your personal needs.

Specifications & Performance

To understand where the Radeon RX 6900XT sits within the RX 6000 series range, let’s take a brief look at the specs.

Radeon RX 6800:

  • 60 compute units
  • A game clock of 1815MHz
  • A boost clock of 2105MHz
  • A 128MB Infinity cache
  • 16GB of GDDR6 memory
  • A total board power of 250W.

Radeon RX 6800XT:

  • 72 compute units
  • A game clock of 2015MHz
  • A boost clock of 2250MHz
  • A 128MB Infinity cache
  • 16GB of GDDR6 memory
  • A total board power of 300W.

Radeon RX 6900XT:

  • 80 compute units
  • A game clock of 2015MHz
  • A boost clock of 2250MHz
  • A 128MB Infinity cache
  • 16GB of GDDR6 memory
  • A total board power of 300W.

The RX 6900 XT is for a smaller percentage of gamers when compared to the other more affordable options. If you’re someone who strives for only the best hardware, or maybe you are a keen 4K gamer, the RX 6900 XT makes a lot of sense and will even save you hundreds when compared to Nvidia’s RTX 3090.

Not everyone wants to play in 4K but a card that is capable is going to give you even better results in 1080 and 1440p. Still, for those that are after the absolute best from a graphical standpoint, this is the GPU for you.

If the absolute maximum performance is something you decide you don’t need, it may be worthwhile you check out the RX 6800 XT for a cheaper alternative.


When it comes to a gaming PC, the graphics card tends to cost around 50% of the overall build. This is because the GPU is the most important component for most gamers. Currently, the stock is a bit of an issue, meaning many are having to wait months for a new card. This gives you an opportune moment to potentially save up more cash for your build, so you know, silver lining and all that.

The RX 6900 XT is priced in-between the RTX 3080 and 3090 at around $1000. This can save enthusiast-level gamers hundreds if opting for the Radeon over the GeForce card. Whether this price is worth it when compared to the RX 6800 XT is going to be down to your own personal needs.


Graphics card physical sizes have been increasing a significant amount over the years, with both AMD and Nvidia’s “flagship” GPUs being the biggest we have ever seen. The size of a GPU is very important to consider before buying, as you need to make sure it fits inside your case. It is also well worth your time checking to see how many slots the GPU will take up on your motherboard, because if you are running a setup with a Wi-Fi card or sound card, you may need to opt for a less beefy option.

What PSU Wattage Will I Need For the RX 6900XT?

Choosing the right PSU for your build is crucial but with many manufacturers now offering efficient models, you just need to focus on getting the right wattage for your components. You aren’t going to need more than an 850W PSU for your RX 6900 XT as that is what AMD recommends. A good quality PSU should last more than several years, so if you think you may get a significant GPU upgrade in that time, consider getting a bit more PSU wattage headroom, although 850W is going to have you covered for quite some time.

RX 6900 XT Vs. RTX 3090

From a gaming standpoint, both the RX 6900 XT and the RTX 3090 deliver very similar results across a wide selection of games. It is worth noting that the RTX 3090 brings more VRam and higher FPS counts to the table but whether this is going to be worth the extra few hundred is going to entirely depend on your individual needs.

For streamers, there is clearly a lot of value in going for an RTX 3090 but with the RX 6900 XT sitting closely to $1000, it is an absolute steal for the performance this will provide your system. We are still waiting for further benchmarks, especially with the SAM and Rage mode in AMDs software, but the value seems to still sit with AMD.

From what we have seen, the RX 6800 XT and RTX 3080 are still probably the way to go for the vast majority of gamers. These GPUs offer incredible performance for gaming and cost nearly half as much in some cases but we understand that some of you simply want “the best”.

Understanding The Specs

Like with any component, it is important to familiarize yourself with the product’s specs. By having an understanding of the key specifications, you will be able to make a more informed decision with what GPU you go for. This in turn is going to ensure you make better investments for your individual needs going forward.

Let’s take a look at some of the main terms you are likely to come across.

Clock Speeds

Clock speed or clock frequency is the speed at which your microprocessor operates. GPUs come pre-clocked to a certain speed and this will usually show in the specific model’s specs. This spec lets us know how fast the GPU will perform certain tasks and while some manufacturers like to show off the speed, don’t let this be your defining factor when choosing a new card.

As mentioned in the specs near the top, the advertised speeds at launch for the RX 6900 XT were a game clock of 2015MHz and a boost clock speed of 2250MHz.


VRAM is your graphics card’s video random access memory. This has a direct impact on how well your card can perform certain tasks and hope much data it can store and access at any one time. VRAM works just like your system RAM, it stores important data used by a game or application that is running, allowing the GPU to access that data at any time. This means the GPU doesn’t have to go between the CPU and your primary drive to collect the data – it already has it stored and ready to go.

The RX 6900 XT comes with 16GB of DDR6 memory.


TDP (Thermal Design Power) refers to the maximum amount of heat a computer chip, such as a CPU or GPU, can produce in watts. This is used as a basic indicator of power consumption. Essentially, more watts equals better performance but obviously comes with higher temps and more power being consumed.

The RX 6900 XT Founders is advertised as using 300W of power but we will have to wait and see what the aftermarket models require as more information is released but we imagine it is the same.

Smart Access Memory

With AMD’s recent CPU and GPU launch we learned that when you combine the two, you can take advantage of a performance boost thanks to the new “Infinity Cache”. The software allows the CPU to directly access the GPUs full memory buffer, as opposed to the 256MB segments that have been the norm until now. Smart Access Memory basically means more efficient use of the combined memory from both the CPU and GPU, which reduces buffering and latency.

Benchmarking is still underway to truly test out this software and to see if there are worthwhile gains to be had from going all AMD.

Rage Mode

Rage Mode feature on AMDs software for the new GPUs. This is basically a “one-click” function that overclocks the card and takes advantage of the additional capacity. Rage mode is one of three new exclusive performance tuning presets found in the Radeon software. The aptly named “Rage Mode” brings out the maximum performance of your card and get every drop of FPS you could want.
