News AMD's RX 7900 XTX Matches an RTX 4090, While Using 700W of Power

[Admin]

AMD's RX 7900 XTX was recently modified to run without a power limit, allowing the GPU to achieve RTX 4090 performance in 3DMark while consuming 700W of power.

When in doubt, push more power!

But.....can it run Crysis?

 

[Fleshharrower]

Neat - How long can it run at that power level? I mean I can run my RTX 4090 at RT X 4090 performance levels all day long

I'm guessing not very long. Unless they are using liquid nitrogen for cooling. 🤣

There's still hope for AMD, if Nvidia in hubris will go back to Samsung in order to save some dollars maybe they'll manage to compete again next time. Or the time after that. Never lose hope, Lisa!

Nope. If 7900 xtx built this way, they gonna add extra components to PCB to stabilize & optimize power delivery, making it running all day long as stock like 4090. They didn't do it simply because of cost & market positioning. This mod proved what AMD said about RDNA 3 was true - they can build 4090 competitor if they want to.

 

[Thunder64]

If they wanted to build a a 4090 competitor it would have more CU's at sane clock speeds for power reasons, not overclocking a 7900 XTX to the moon. Anybody could tell you that.

Anandtech called from 2004 and wants its funny comment back.

It has though.

You might have missed the part where it needed 700 watts in order to reach 4090 levels of performance. A couple of years ago Ampere was said to be a power hog because the RTX 3090 required exactly 350 watts... It's not really cost and market positioning that stopped them, it's just the sheer ridiculosity of a GPU that would have required a 1200 watts PSU as a bare minimum.

700 watts of power? You're going to need massive cooling to keep that thing from melting down.

Last someone tried that trick was nVidia. I'll let the youtube video explain why it was a bad idea.

Yeah but the article says that the 7900xtx scores 10% higher than some 4090 models so if we decrease clocks by 10% (from 3.3ghz to 3.0 ghz) then the voltage needed would decrease significantly (due to bringing the gpu core down the voltage -frequency curve toward the efficient area of the curve. I would guesstimate that the 7900xtx would need 500-550 watts in this case which is still worse than 4090 but not outrageous like 700 watts.

 

[BeedooX]

So what I'm reading here is that AMD's 7900XTX was a 4090 class card - and rumours were likely true around the discovery of some defect prior to release, resulting in much higher power requirements than expected, and ultimately obscuring the card's true performance.

 

[8086]

indeed

I know that MLID guy gets a fair bit of hate, but what about Jim at AdoredTV?

They could've done a 4090 competitor, but chose not to? 🤔

 

[ilukey77]

problem is they are playing catch up now they needed the 7900xtx with 4090 like performance at the release ..
even if they bring the 7950xtx the 4090ti will eat it ..
right now if i was AMD id look at end of life 7950xtx then swing really big at Nvidia for the 5090 with the 8900xtx leaving performance on the table for the 5090ti and 8950xtx !!

I dont like where the GPU technology is heading ... every generation is becoming more and more power hungry. They need to focus their research on low power . Once Steve Jobs opened Intel eyes when he made the first MAC AIR and asked Intel to produce a special CPU for him. and thats the reason Apple Today left Intel and made their own CPU .. I predict that in time Apple will start making their own dedicated GPU for teir high end workstation .and they will crush Nvidia and AMD. I give it 10 years from now.

Crysis 1 came out in fall 2007. The original Far Cry came out in the first half of 2004 and could actually run fairly well on newer GPUs of the the time.

Yeah, it's more like showcasing it's doable, not a real retail card.
I guess it could work with some garden hose sized watercooling setup.
but that's likely the reason why AMD did not go for 4090 competitors.
at full unlocked die, it would likely eat ~550W, and stil lget slapped in RT.

 

[Makaveli]

It has though.

Yup been old for 20 years now and lost its funny along time ago.

now comes across as try hard

 

[Amdlova]

They trying moving attention from burning ryzens to burning radeons ... don't worry AMD wii bring Red glow for everyone.

 

[Avro Arrow]

It's kinda like what AMD did with the FX-9590 and what Intel did with their 13th-gen CPUs.

"When you can't compete normally, OC the hell out of it!"
🤣🤣🤣

And it would STILL require a cooling solution similar to the nVidia FX 5800.

And we all would be laughing at them for even trying that. Just like we did nVidia.
