XFX Speedster QICK308 Radeon RX 6600 XT Black Gaming review


XFX Speedster QICK308 Radeon RX 6600 XT has dimension of ‎10.79 x 4.49 x 1.97 inches and weighs only 2.86 pounds.


Power comes via a single 8-pin connector, and the card comes with an HDMI 2.1 connection and three DisplayPorts.

Frame rates

Fantastic performance across the board from AMD with their new Radeon RX 6600 XT killing it in Assassin’s Creed: Valhalla with 83FPS average at 1080p. This is beating the GeForce RTX 3070 Ti at this point, but it is a Radeon-friendly title.

The XFX Merc 308 Radeon RX 6600 XT does just one thing—ultra-fast 1080p gaming—but it does it very, very well. And it does it for a whole lot cheaper than the ROG Strix. Look elsewhere if you have a 60Hz 1080p monitor though, or if you want to play at 1440p resolution. The 6600 XT does each well enough.

Shadow of War is more punishing, knocking the RX 6600 XT Down to “just” 127FPS average — losing to the previous-gen RX 5700 XT and GTX 1080 Ti. Metro Exodus has the RX 6600 XT matching the RX 5700 XT with 53FPS average.

Temperature & Cooling

The GPU under the hood is producing 130W TGP and 160W TBP of heat in a default configuration, so likely the cooler has a 250W thermal power design. We’re looking at ~33 DBa values under load and temps closer to the 70 Degrees C range, all fine. Board analysis also shows all critical components are tied to some form of cooling. FLIR imaging shows the card is hardly bleeding heat. Overall, we’re very comfortable with what we observe.

Power consumption

Heat output and energy consumption are closely related to each other, as (graphics) processors and heat can be perceived as a 1:1 state; 250 Watts in energy consumption approaches close to 250 Watts in heat as output. This is the basis of TDP. AMD is listing the card at 160W, which is okay at best for a graphics card.


The new Radeon RX 6600 XT has 8GB of GDDR6 memory clocked at 16Gbps on a 128-bit memory bus with 32MB of AMD Infinity Cache (down from the 128MB on the higher-end Radeon RX 6800 XT for example). Infinity Cache helps the Radeon RX 6600 XT swing above its weight, especially when compared with previous-gen GPUs in the same “price range” as the RX 6600 XT.

XFX Speedster QICK308 Radeon RX 6600 XT Black Gaming customer review

I actually got one of these!

Im schizophrenic and mine ethereum because i can’t hold a job, I also think if you have a problem with ether mining your thought process is backwards, if you spend big money on a gaming pc that you would otherwise waste countless hours of your life on (gaming is an addiction, not a noble pursuit, my World of Warcraft account has over 3 years /played on it) you can now pay it off and upgrade “for free” every year, so if youre a gamer and you refuse to mine it comes off as immature and stubborn. You can’t get what you want when you want it so you blame the people you think are preventing you from having it and throw a tantrum. Now that thats out of the way this is an excellently built GPU and makes my other 6600xt feel like cheap plastic in comparision. It gets 32.8mh/s 33.5mh/s with fast timing but im not positive fast timing is stable. It handles 2k fine on lower settings in borderlands 3, definetly worth the $600 in this market.

AMD Radeon RX 6700 XT

Memory: 12GB GDDR6 | Memory bandwidth: 384Gbps | Memory bus: 192-bit | Base clock: 2,321MHz | Boost clock: 2,581MHz | Stream processors: 2,560 | Process: 7nm | Power: 230W

AMD’s Radeon RX 6700 XT is a price performer with a listing of about $480. It costs more than the RTX 3060 Ti, but it also delivers better raw power. This is especially important for those who want to push QHD frame rates and don’t care as much about ray tracing or image upscaling.


  • Stellar 1440p (QHD) performance
  • 16GB of VRAM
  • Capable of ray tracing
  • Costs less than other RDNA 2 cards


  • Costs more than RTX 3060 Ti
  • Ray tracing and FSR support not as good

While the RX 6700 XT offers ray tracing, its support isn’t as good as NVIDIA’s, and you will likely see a harder hit to performance. This is true even though AMD’s cards now have FSR, an alternative to DLSS.

The AMD Radeon RX 6700 XT slots in somewhere between the NVIDIA RTX 3060 Ti and NVIDIA RTX 3070 in terms of raw performance. It also costs about $80 more than the list price of the 3060 Ti, so you have to be sure you’re looking for better power and not a better feature set. If you want to push high frame rates at 1440p and even want to dabble a bit at 4K, the RX 6700 XT will do a great job.

Bottom line? The 12GB of VRAM sets the RX 6700 XT up nicely for the future, and FidelityFX Super Resolution is beginning to cut into NVIDIA’s DLSS technology. If you can find an RX 6700 XT close to retail price, it should make a great card for QHD gaming.
