The rumours are really interesting - Radeon RX 7900 XT could hit 4 GHz clocks! :eek: o_O

AMD RDNA 3 "Radeon RX 7000" GPUs Allegedly Hit Almost 4 GHz Clock Speeds, Refined Adaptive Power-Management & Next-Gen Infinity Cache Confirmed (wccftech.com)

I'd say, highly unlikely....

For now, dream on.....
 
Reminds me of when those "4GHz" clubs were around in the mid 00's. It's come full circle with GPUs now. You just need a PSU to handle the fire-breathing cards.
 
Could've been more believable if it came from someone not named 9550pro with ATI logo on the banner :D
 
If true, it is going to be awesome.

Navi21 5120*2*2500mhz = 25,6TF
Navi31 12288*2*4000mhz = 98,3TF

4 times the performance!
 
It's logical to assume that splitting pure compute from memory controller & infinity cache would lead to increased clocks but how much more was difficult to assess because we didn't know how these 2 affecting each other.
GPUs always had multiply internal frequencies depending the segment, for example infinity cache is connected to the Graphics Engine at 1.94GHz (boost clock) in Navi 21.
The same leakers that were saying that Navi 21 hits 3GHz the same now are saying close to 4GHz (close is what 3.9GHz?) for Navi31, but even If this rumor is correct we shouldn't exclude instead of 2250MHz that RX 6900XT was, something like only 2925MHz boost even if near 4GHz is true.
On the other hand if Navi24 at 6nm could hit 2.815GHz turbo I don't see why at 5nm not to be able to go at 3.1GHz, now add the clock benefits from compute/memory controllers+infinity splitting, so even higher than that.
But all depends from TBP, at 350W the reference boost clock shouldn't be more than 3GHz anyway I would guess.
Still near 4GHz when pushed to the absolute limit is a surprise (if true...)

No. Pretty sure they meant 3ghz or are just fanboying out.
 
We will know better in the very beginning of November. Good.
 
7900XT 3.6ghz ~ 1000usd
7900XTX 3.7ghz ~ 1100usd
7900XTXH 3.8ghz ~ 1200usd
7900XTXHXHXH 4ghz ~ 2000usd
 
NVIDIA GeForce RTX 4070, RTX 4060 & AMD Radeon RX 7950 XT, 7900 XT, 7800 XT, 7700 XT Graphics Cards Listed By Enermax

The full list along with their wattage (using an AMD Ryzen 9 7950X CPU for reference) are listed below:

  • NVIDIA GeForce RTX 4090 (733W)
  • NVIDIA GeForce RTX 4080 (600W)
  • NVIDIA GeForce RTX 4070 (565W)
  • NVIDIA GeForce RTX 4060 (478W)
  • AMD Radeon RX 7950 XT (702W)
  • AMD Radeon RX 7900 XT (610W)
  • AMD Radeon RX 7800 XT (580W)
  • AMD Radeon RX 7700 XT (478W)
According to this, it looks like RTX4060 and RX 7700XT have around 200W TBP! (and around 420W for 7950XT, 330W for 7900XT, 300W for 7800XT)

Not bad given that the RX 6700 XT is rated at 230W.

Where are the leaked benchmarks of RDNA 3? :mad:
 
You can make an educated guess - the percental increase in clock speed of zen 4 over zen3 - more or less for GPUs as well -

Although with chiplet design - more mhz could be added as cache memory is outside the die.
 
im quite open minded in Sutch things so i say good until proved otherwise. but it do sound a bit iffy, on LN2 i wouldnt bat a eye lid but water?. we will see eh.
 
That kind of frequnces seems like a way to reduce latency in gaming.

Not bad at all!
Apply the 50% performance/Watt at 7900XT or 7800XT and things may look good (unless the 50% apply in a very limited and specific games suite, not unlike what we had with Ryzen 7950X which was supposed to be 11% faster than 12900K according to AMD)
Regarding benchmarks i suppose AMD will identify 4090's raster weaknesses first and then starting to leak specific results that make them look good in order to generate hype, it shouldn't take too long.
Based on final specs with 2.7GHz average clock, RTX 4090 raster performance is a little bit disappointing around 10% worst (or more) of what i was expecting.
Supposedly the blame is CPU limited games, i wonder what AMD's results will be in the same TPU testbed.

I don't think that's cpu limit, more like game engine limited.
