Default GPU Frequency
With both NVIDIA and AMD GPUs, the GPU frequency is dynamic. NVIDIA has GPU Boost, and AMD has its Game Clock and Boost Clock quoted frequencies. Typically, GPUs today can exceed the “Boost Clock” dynamically. We need to find out what the GPU frequency is while gaming. To do this we will record the GPU clock frequency over time while playing a game. We use Cyberpunk 2077 for this with a very long manual run-through at “Ultra” settings recording GPU-Z sensor data.

Note that the version of GPU-Z that we used, v2.51.0 does not currently support the new Radeon RX 7900 XTX GPU. Therefore, take these readings with a grain of salt, we aren’t entirely sure which GPU frequency domain it is reading, the front side clock or the shader clock.
According to GPU-Z, the frequency starts off at a very high 2609MHz, but then drops to around 2569MHz and maintains a clock between 2510-2570MHz. Taking an average of the results, the average clock speed comes out to 2547MHz. According to the official specs, the Game GPU Clock is 2300MHz while the Boost GPU Clock is 2500MHz. Therefore, if GPU-Z is reading the “shader clock” correctly, the video card is boosting over the 2500MHz boost clock while gaming and maintains above that frequency on the made-by AMD video card. We can also see that it is quite dynamic, and doesn’t maintain a constant clock, it varies quite a bit.

Join Discussion →Pretty much what I expected. On par or better than the 4080 at rasterization. But gets stomped to death in ray tracing.
Still...for raster workloads it's a bargain.
Now it's just a waiting game for EK to make water blocks for the OC non-reference cards.
Yup - no surprises, which I think is good because I had pretty high expectations to begin with and it pretty well met them.
Now to see how availability and the scalpers play out.
Also can’t wait to see what the power data shows.
Great review thanks
Seems better then my 3080 now to see European prices.
Very nice this card is something to be excited about. ESPECIALLY with AMD's 'Fine wine' methodology to their drivers.
Ray Tracing. 4K is for Ray Tracing.
price is acceptable, but why is the XT even a thing at 899? It wont sell.
Too bad AMD cant figure out how to do more for RayTracing......
Considering they are pretty much on par with 3090's for RT performance that isn't bad. The question is did they revise their RT processing ability to make it stronger and just haven't been able to properly flex it in drivers yet?
I'm perfectly fine with slower RT performance myself - it isn't an important feature. By the time I actually care about RT we will probably be 3+ generations removed from today's cards.
If it's anything like the 5000 and 6000 gens of XT and XTX -- the XT would overclock to darn near the same performance level as the XTX for a few dollars less, and that made it a pretty attractive option.
I don't run RT in any game other than CP2077. I'm an FPS wh0re. So rasterization performance is king in my court. The 7900XTX gets it done for an attractive price....hopefully. LOL We'll see what the AIB OC cards come in at. I have a feel that those with 3x 8 pin power are going to be overclock beasts so long as you can keep them cool. Well, dangit, I watercool all the things. So, we'll see.
I never thought I'd see the day where a $999 card would be considered a bargain... :rolleyes: :rolleyes:
I did expect more from the XTX, sure it beats the 4080 at 1080p and meets or beats it at 1440p, but it looses at 4k for the most part and this is where this card should shine. And that's not even taking DLSS2.x and 3.0 into account.
Not a bad card by all means, but I really hoped for a real RTX4080 KILLER, you know? that card that's been promised generation after generation, but has yet to come.
Refreshing review, nicely done. Very modern RT titles that had exposer to RNDA2, current gen consoles, FarCry6 and Spiderman does very well with RT. Older mostly driven Nvidia RTX titles, DXR 1.0 era takes a significant hit.
Point is RT performance is also heavily dependent upon how programed or optimized for. I don't think AMD rt performance is as powerful as Nvidia's but also think it may not really be that far behind. Newer games will show this or not.
Very tempting buy for a number of reasons.
Maybe I'm looking at the wrong numbers, but the XTX beats the 4080 in every single rasterizing benchmark FPSR threw at it with just one exception: When upscaling is used and DLSS is available and FSR is not (Watch Dogs)

It's not beating a 4090, but it's certainly knocking on the door there. But the 4080? Yeah, the XTX has is beat, until you turn on RT.
Even looking at RT - you are still at 3090/Ti levels, which even just that still costs more than the XTX MSRP.
I have to say I'm not looking at just this review benchmarks, but what I've seen in other reviews.
One thing is for sure, nvidia will have to reduce the price of the RTX4080. $200 for the "nvidia tax" is just too much even at that price range.
Its clear people were waiting for the 7900XTX release and it may have payed off one way or the other.
