RX 7800 XT Vs RX 6800 XT: Should You Upgrade?

This comparison will measure the strengths and weaknesses of the RX 7800 XT against the RX 6800 XT in terms of gaming framerate, power consumption, and temperatures.

The current generation of graphics cards has been guilty of not giving substantial performance increments over the previous generation, and no card has felt this harder than the RX 7800 XT. In this RX 7800 XT vs RX 6800 XT comparison, we will measure the performance of both cards to see what new upgrades AMD has brought to the table.

Key Takeaways

  • The RX 7800 XT was around 9% faster in our gaming tests than the RX 6800 XT.
  • Temperatures were around 10°C cooler on the RX 7800 XT because of its lower power draw and overbuilt cooler (varies from model to model).
  • The RX 7800 XT can be had for around the same price as the RX 6800 XT in the new market.

Architectural Differences

  1. Process Size: The RX 6800 XT has 7nm manufacturing nodes, whereas the newer RX 7800 XT uses a chiplet design, making use of both 5nm and 6nm processing nodes. This allows for significant cost cuttings as some parts of your GPU, like the I/O handler and memory, need such complex manufacturing processes.
  2. Clock Speed: Despite the more complex and power-efficient manufacturing process of the RX 7800 XT, its predecessor has a higher base clock than at 1825MHz. In contrast, the newer card has a base clock of 1295MHz. Thankfully, the RX 7800 XT takes the win in boost clock with a frequency of 2430MHz over the RX 6800 XT’s 2250MHz boost.
  3. TDP: The RX 7800 XT has a rated TDP of 263 watts, whereas the maximum power that the RX 6800 XT can draw is around 300 watts. Both cards use the same 2×8-pin power connector.
  4. VRAM: Both cards come up equally matched in terms of memory as well, with 16GB of GDDR6 memory over a 256-bit bus. The memory of the RX 7800 XT does have a higher speed at around 620 GB/s, whereas the RX 6800 XT’s VRAM has a data rate of 510 GB/s.
  5. Other Features: Both the RX 6800 XT and RX 7800 XT can use AMD’s Fidelity FX super-resolution, which can greatly boost your framerate. The RX 6800 XT does have more compute units than the 7800 XT, which matches itself with the non-XT variant of the older card.
    That, in addition to the fact that AMD hasn’t announced a non-XT version of this card yet, indicates that the 7800 XT is not the successor to the 6800 XT. Instead, it was made to compete with the RX 6800 non-XT.

Benchmarks

The differences between the RX 7800 XT and RX 6800 XT seem to show the former to be a worse performer on paper, but the real-world performance of these cards might tell a different story.

To put numbers to these assumptions in performance, we put both cards in our test bench with the Ryzen 7 5800X3D and 32 gigabytes of RAM to test a slew of games at the 1440p resolution.

Starfield

Starfield Performance

  • Using Nanite and Lumen in the Epic quality setting at 1440p in Fortnite challenged both the graphics cards. The RX 7800 XT reached an average framerate of 83 FPS, whereas the RX 6800 XT had an average framerate of 75 FPS.
  • There was a noticeable difference in the smoothness of the game on either card, likely due to the difference between the 1% lows. The RX 6800 XT had a framerate of around 52 FPS at minimum, whereas the RX 7800 XT had a minimum framerate of around 63 FPS, greatly lowering its stutters during heavier sections of gameplay.

Overall Performance

Now that our tests have shown us the reality of the RX 7800 XT vs RX 6800 XT, this part of the comparison will focus on finding solid grounds on the basis of all the tests we’ve performed to determine which GPU excels in what tasks.

Framerate

Average FPS Performance
Average FPS @1440p (Image By Tech4Gamers)
  • The RX 6800 XT provided around 94 FPS on average in our gaming tests at 1440p, whereas the RX 7800 XT was ahead by around 9% with an average framerate of 101 FPS.
  • Stuttering was not an issue on either card, according to our testing. The RX 6800 XT reported 1% lows of around 77 FPS, whereas the RX 7800 XT provided around 83 FPS when scenes got more challenging.
  • Our testing suite did not include ray tracing, but it is safe to say you’d gain an additional 5% lead on top of the advantage the RX 7800 XT already has if you choose to turn ray tracing on.
  • The tests we conducted were also independent of any AI upscaling, but you can easily get a 25-35% boost in performance if you turn FSR on using either card. The dedicated AI accelerators on the newer card might give it a slight edge over the 6800 XT in terms of this feature as well.
  • Neither the RX 6800 XT nor the RX 7800 XT support frame generation at the time of writing this article, though you can “double or even triple your framerate” using AMD’s Smooth Motion Frames when the feature drops on both cards.

Power Consumption

Average Power Consumption
Average Power Consumption @144p (Image By Tech4Gamers)
  • We saw a peculiarity in our power consumption reading. On average, our gaming tests showed the RX 7800 XT to draw power in the neighborhood of 265 watts, whereas the RX 6800 XT drew only a couple more watts at around 270 watts. These tests were done using the MSI Afterburner software.
  • When we measured the total system power draw, the difference was much more than our MSI Afterburner readings indicated. Our test bench drew around 447 watts when using the RX 6800 XT, whereas using the 7800 XT dropped the power consumption to around 390 watts.
  • It is safe to say that our total system power measurements are more indicative of something that would concern most people in real-world use, but the power draw readings of the 7800 XT were confusing nonetheless.

Temperature

Average Temperature Performance
Average Temperature @1440p (Image By Tech4Gamers)
  • The RX 6800 XT had an average peak temperature of around 64°C, whereas the RX 7800 XT was much cooler, chilling at an average temperature of around 54°C.
  • We tested the Powercooler Hellhound variant of the RX 7800 XT, which has a very overbuilt cooler for its power draw. This made it chilly throughout our testing, whereas our reference model RX 6800 XT got a bit warm.
  • The temperatures you experience on the card you end up buying can vary drastically on several factors, so take these numbers with a grain of salt.

Price And Availability

  • The RX 7800 XT dropped for an MSRP of $499 a few days ago, whereas the RX 6800 XT had a launch MSRP of $649, but it can also be had on Newegg for around $499.
  • The RX 7800 XT and RX 6800 XT should be readily available at any computer parts retailer of your choosing all over the world.

RX 6800 XT Vs RX 7800 XT: Which One Should You Go For?

Now that we’ve discussed all the moving parts in play that give these cards their flare, this part of the comparison will evaluate the RX 7800 XT vs 6800 XT in terms of a whole package so you can spend your hard-earned cash on the best deal for you.

  • With the equivalent price and extra performance of the RX 7800 XT, it seems like we finally have a graphics card worth upgrading to in the new generation of GPUs.
  • The RX 7800 XT performed around 9% better in our gaming tests whilst costing the same as its competitor. This makes it the card to get for anyone looking for a good deal. 
  • The RX 7800 XT had a total power consumption of around 60 watts lower than its predecessor, making it the better choice for anyone looking for a more power-efficient card as well.
  • The lower power consumption of this card paired with most industry standard coolers makes this card noticeably cooler than the RX 6800 XT as well, unlocking some overclocking potential.
  • Though the RX 7800 XT shares a name with its predecessor, it is more of a successor to the RX 6800 non-XT, which explains its lower launch MSRP.
  • Both cards are adequate performers, so getting a deal worth buying for RX 6800 XT would net you excellent performance for 1440p gaming. 
  • Both graphics cards share a very similar feature set, though the ray tracing performance of the newer card is noticeably better than its brethren.
  • Both cards will enjoy AMD’s upcoming Smooth Motion Frames technology, slated to launch in the next few months. This will allow these GPUs to stay relevant for much longer and enhance your gaming experience.
  • To summarize, the RX 7800 XT and 6800 XT are both great graphics cards for a low price, but all else being similar, the performance of the new card finally gives us a definitively better card than last-gen.
