AMD's Navi 31 Might Clock to 3 GHz, Partner Cards Will be Able to Overclock
Based on details from a PCWorld livestream following AMD's launch of the Radeon RX 7000-series, it was revealed that AMD has designed the Navi 31 GPU to be able to scale as high as 3 GHz. In other words, it appears that AMD has power limited its cards, at least for the SKUs that the company has announced so far. This could be for many reasons, but most likely to try to find a balance between power and performance. The details of the 3 GHz scaling did however not come from AMD directly, but rather from Jarred Walton over at Tom's Hardware. That said, the information was apparently shared with the media by AMD at the event.
In the livestream, it was also confirmed that partner cards will be able to overclock, so expect to see some factory overclocked cards, with higher power draw. This could be why, in part, that ASUS went with a much larger cooler on its TUF Gaming Radeon RX 7900-series cards. As ASUS didn't reveal any clock speeds or TDPs of its two cards, we don't really know what to expect, but we'd be surprised if these cards weren't factory overclocked to some degree when they launch in December.

mind you that's at 4k, at 1440p I wouldn't be surprised if the core oc gave a slightly bigger boost
Interested to see what custom Navi 31 designs will do. Probably huge diminishing efficency returns over 400w or so but we'll see.

The peak power on only 2 x PCI-E 8 pin cables was 646 watts, is roughly 53 Amps.
Yes wires will get warm, but generally if it is a good build PSU with quality cables you can easily do this.
I have never seen such a thing that a card with 3 vs 2 8 pin cables suddenly overclocks worse. As long as input voltage supplied to your GPU's VRM is stable your good. And thats why (lots) of capacitors exists on graphics card anyway.
Oc'ing is dead anyway. GPU's pretty much clock to what it is capable of. The best you can get is a undervolt and lower consumption, with perhaps a little bit of performance. But thats about it. Many years ago i installed a vapochill on a Ati Radeon 2600 Pro card. The core clock ran at 600Mhz stock and i was running at somewhere around 1300Mhz with a 2.1V core voltage and -40 degrees temps. It did blew up during the 3Dmark nature run and to be honest you wont be getting these "fun" clocks anymore compared to these generation(s) of hardware.
You buy a card that matches to what you want and thats it.
355W + 17% = 415W and that is only on the same voltages. If more volts then the +17% can easily be +25~30% in wattage (=440~460W)
1.5x + 17% = 1.75x ...and this is with linear increase for clock/wattage vs perf.
I think its too optimistic to say 2.0x
Maybe if we accept the 1.5~1.7x, then... + 17% = 1.75~2.0x (up to 2.0x) and again with linear increase of power/performance.
Could be or not... depends on the headroom of the efficiency curve, but I would assume that AMD already took advantage of it.
Personally I expect it to be trading blows with 4090 at the 430~450W region in rasterization and the same with 3090/Ti in RT.
AMD is quoting a 60% RT performance increase with a maximum of 80%.
So in something like Control with no Ray Tracing we are seeing the 6950XT at 56.9 FPS at 4K Ultra and 23.6 with RT ON
Taking the above into account using the 6950XT as reference
3090Ti vs 4090 vs 7900XTX
Control: 40 vs 68 vs 40
Cyberpunk 2077: 24 vs 41 vs 21
Deathloop: 66 vs 121 vs 74
F1 2022: 49 vs 85 vs 54
Far Cry 6: 77 vs 96 vs 126
Metro Exodus: 71 vs 116 vs 78
Resident Evil Village: 102 vs 175 vs 142
Watch Dogs Legion: 48 vs 75 vs 64
Obviously not a perfect setup as RT and Rasterization performance will likely scale differently but if the 7900XTX is 1.6x faster in both rasterization and ray tracing a direct 1.6X to 1.7X best case would result in performance similar to the above.
Seems to me. This is how the product stacks will likely compare.
RTX 4090 = _________
__________ = 7900XTX
RTX 4080 = 7900XT
RTX 4070 = 7800
RTX 4060 = 7800
RTX 4060 = 7700
RTX 4050 = 7700
Can easily get it to boost above 2.65GHz without ever going over 300W and keeping my temps under 80°
RTX 4090 ~~ RX 7900 XT 20 GB
RTX 4080 Ti ~~ RX 7900 / RX 7800 XT
RTX 4080 ~~ RX 7800 XT 16 GB
RTX 4070 Ti ~~ RX 7800
RTX 4070 ~~ RX 7700 XT
RTX 4060 Ti ~~ RX 7700
RTX 4060 ~~ RX 7600 XT
etc.
i dont wanna open a discussion about what what, but cause alot ppl have this understanding and mentality, we are now paying 2k for card ! keep doing so bro ! we need alot from you.
I really hope Nvidia cards will stay on the shelf forever.Because RTX 4080 is cheap, right ? Putting that into perspective, the 4080 is even worse than 4090, price wise.
"Just buy this one, it has our logo, so it's the best product in the universe"
Nvidia launches $1600 GPU that fries the cables and there are people talking about reliability. Plus, If you're talking about software, I invite you to see the dozens of bugs that both AMD and Nvidia clearly announce with every driver release.
