Test Rig
For our tests, we used a test rig which includes the ASRock Z790 PG SONIC motherboard
All tests were conducted at turbo clock speeds at a resolution of 1920×1080. High or Ultra settings enabled.

As you can seen from screenshot below … the RX 7900 XTX is based on AMD’s Navi 31 (RDNA 3) architecture using the 5nm FinFET process. It uses 24GB of GDDR6 ram running at the faster 20Gbps on a 384-bit memory bus.
PassMark – Performance Test 9.0 (3D Test)
Test the speed of your 3D video card by selecting from options such as fogging, lighting, alpha blending, wire frame, texturing, resolution, color depth, object rotation and object displacement. Separate tests for DirectX 9,10,11 & 12. With support for 4K resolution.
Load Temperatures
After hearing all the negative experiences from users, about the Radeon RX 7900 XTX’s GPU hotspots reaching 110 degrees Celsius, I was a little worried if our custom Radeon card from ASRock will suffer the same fate.
Luckily at full load, the card reached a high of only 60 degrees Celsius, with the GPU Hotspot reached a maximum of 106 degrees Celsius, but averages just under 100 degress Celsius. It’s still high, but didn’t affect performance or caused any throttling. Remember, this card uses a factory-overclocked GPU, so considering the fact it isn’t too bad.
It seems the ASRock Phantom Gaming 3X cooling solution is doing a great job of cooling the graphics card. This is all thanks to the large heatsink with 7 heatpipes and triple ring fans. So no complaints here.

106º is pretty bad, my MBA model stays at 80º on the hotspot
We tested the card at 100% load … no throttling and no issues, plus it uses an overclocked GPU. It peaked at 106 but averages around 100, which i think is acceptable.
Winston i heard that several users I dont own this have tighten screw on backplate and got better hot spot temps cause the backplate werent properly seated i dont know if its true . I test a XT tuf hotspot is 79c . Thanks for a good reveiw buddy though.
Ok let me check… maybe I should tighten the backplate a little more 😆
How was it, did you manage to get any better temps with tightening the screws/other stuff. That 106 seems high, especially with the difference between GPU edge and junction temps being 46 Celsius. The reference models are considered faulty if the temp difference is over 40C (and junction reaches 110C). As I already had one such card, I am hesitant to be burned twice (pun intended) by a 7900 XTX 😀
Hi there, Winston you wrote that : ” the ASRock Phantom Gaming 3X cooling solution is doing a great job of cooling the graphics card. This is all thanks to the large heatsink with 6 heatpipes and triple ring fans.” And I had the impression that the ASRock Radeon RX 7900 XTX Phantom Gaming 24GB OC Graphics Card comes with 8 Ultra-fit heatpipes, according to the photos displayed on the ASRock website… At least I count 8 pipes on their photo. Can you tell me if I am wrong here…??
Actually I recounted … total is 7 heatpipes. I have amended the review accordingly. Thanks 🙏
Heya, for people with bad temps. It seems boost clock is a bit much for the card. I found this thread on reddit: https://www.reddit.com/r/radeon/comments/16g2p5u/asrock_gaming_phantom_7900_xtx_temps/ people suggest to UC (2300-2400 frequency, 1120mv, 2714 ram and +15 pwr), and then FAN speed drop by 500rpm, also power consumption from around 400W to 300W and loose FPS is like 1-3FPS. Can try this settings for you.
