Yet again another "meh" release. More or less same performance as 6800XT... Essentially zero movement after 3 years.

As I said, this generation is busted from both nVidia and AMD. Maybe next generation will be better.

Only if Intel's Battlemage kicks ass. Otherwise, both red and green team have no incentive to move the needle. They will come out with smaller, more power efficient GPUs with pretty much same old performance and still make money.

Very far out the efficiency curve it seems:

Forget the Ada series, if a year ago anyone on this forum even dare speculate that any RDNA 3 SKU would have worse efficiency than a Nvidia Ampere SKU they would have gotten laughed at/banned, yet here we are...
Yeah, for whatever reason (binning) these 7700 XT are the dud of duds. Meet target clock around 1.025v while 7900 XTX and 7800 XT are around 0.925v.

This possibly meant to be sarcastic, otherwise I don't see how did you come to "worse efficiency" than Ampere?
Even RDNA2 is more efficient, let alone 3
Did you look at the graph and actually understood what I said?

The RTX 3070, a Nvidia Ampere SKU is definitely holding its own in efficiency against the 7700XT, an AMD RNDA3 SKU, if you disagree with the results here then take it up with Computerbase, because that's what their testing is showing.

The 7800XT seems like a decent GPU, but would've been nice if TPU's reported OC'ed cards were more typical of third-party AIB samples. I suppose if you consider the Starfield game bundle as saving you $50 when you buy N32, it's not too bad of a deal.

Like, I wouldn't mind $450 for ~6800XT that can be OC'ed to 6950XT performance. Alas, unfortunately it seems AMD put a cap on the 7800XT's max clocks.

I don't hate any company, but I hate the lack of competition...
My point earlier in the thread was about the silicon both Nvidia and AMD were using. I was pointing out the power consumption of Nvidia cards vs. AMD cards. I said that Nvidia was using the best silicon short of 3nm. AMD is a node behind Nvidia cards. Which shows why Nvidia cards are more efficient.

We are on RDNA3. When AMD released RDNA1, they said they were not trying. They had a bunch of (TSMC) 7nm silicon and they wanted to see what it would do on AMD GPU's. Eg. 5700 and 5700xt. The 5700xt lost to the 2070 by the same margin there or abouts which the 7800xt loses to the 4070. I have to ask why is that? The 4070ti, 4080, 4080ti and 4090 are all better than the 4070. It is not as if AMD is trying to take down Nvidia flagship cards.

AMD is flush with cash and a big market cap. Why are they not trying to compete with a high mid low high end card in the 4070?

A 7600xt would probably almost equal the 7700xt, but that card does not exist yet.

I had Ryzen CPU (2017) before most of you. I still have a functioning 7950 in a working system right now. That is circa 2012. So don't accuse me of being a AMD hater. I just expect more from AMD in 2023.

AMD once had the peoples card. The RX 480 with 8GB of vram followed by the RX 580 with 8GB of vram that could be had for $160's to 180ish for quite awhile. Nobody gets upset with a value play card.

You can read my past posts over the last year. I said the 6800xt was always the card to have from AMD. I think people expected the 7800xt to be significantly better than the 6800xt. It makes the RDNA3 architecture seem like somewhat of a bust in comparison to RDNA1 and RDNA2

That graph is based on Metro Exodus RT performance 1% FPS Percentile, and peak load in the same game. At least that gave me a pretty similar result.
During the previous generation, 6700XT also had much worse efficiency than the rest of the lineup.
So your point is what exactly?

Another thing is that these GPUs use too much voltage.
According to TPU 7700XT Pulse uses 1V for 2534-2544MHz in Cyberpunk.
Max OC with 7700XT was >3GHz and <850mV, but tested only in 3dmark.
Meaning that with the same power consumption, you get a more performance.
But of course you have to do It manually.

I was checking availability, and seems that the regular sources have either sold out, or expecting stock. Amazon only had 2 cards, so either folks are buying up these cards, or initial stock of the rx 7800 xt is not as robust as one might think.

Maybe Starfield promo is just too juicy to not wait. It seems that maybe some folks are returning to bad habits, and snapping up initial stock to sell on Ebay. At this rate I don't think sales will go back to normal, maybe for Black Friday. But seeing a $50 dollar discount in say 4-6 weeks on a 7800 xt model might be wishful thinking. They say the Starfield promo ends at end of the month, so who knows.

That's a bit of rose-colored glasses. The $160 price was a fire-sale for the 4GB RX 480, once they wanted to clear inventory for the RX 580. Which the 8GB model was more around $260.

Edit: I stand corrected, I think that it was $229 for the 8GB model. ($30 more than the 4GB model.)

No, the 7700 XT is extremely inefficient compared to other RDNA3 SKUs
Yeah, extremely unbelievably and overwhelmingly shockingly inefficient, as much as 5% short of 7800XT (per PCGH)

The typical voltage difference alone recorded in TPU is more than that. Maybe they got a worse chip. But buyer beware. They're out there and AMD is shipping total duds as 7700 XT.

The introductory price of the RX 480 was $199 for 4GB version and I think $229 for the 8GB version. Then the first crypto craze hit and cooled off. I can give you dates for when the RX580 was always under $200 for months until the next crypto surge. This was after RDNA1 was on the market for around a year. Then all the prices got way out of line. I went back and looked. From around October 2018 through most of 2019 the RX 580 could be found between the $160's up to the $180's when deals were posted. Don't forget about the AMD bundles of X370 and B450/X470 motherboards with processors for $180 for the Ryzen 2600 and went into the low $200's for 2700x bundled processors/motherboards. It was crazy good deals back then.

The RX5700 was as low as $292 and the 5700xt was $340-$380. None of these are launch prices. I am just pointing out after release AMD was very aggressive with their pricing. So much so that reviewers had to ignore the performance difference between AMD and Nvidia GPU's because of the RX5700/XT prices. The value was there.

Tell me I am wrong. Look at what 5700XT's still go for on Ebay. It makes no sense but those were great GPU's when you factored in the price. We are now post crypto and both AMD and Nvidia seem to believe the price for GPU's should remain high. Even the inflated GTX 3070 retailed originally for $499. That was right when things got crazy with GPU pricing.

In the TPU review, AIB 7700xt with ruined already not very good efficiency, looks realy bad compared to the reference 7800XT

Possibly so. But even the reference clocks Sapphire version is about 1V instead of 0.935V of 7900 XTX. So it'll never be as efficient as its siblings unless manually undervolted.

It's (mid range GPUs for tower PCs) a tiny market compared to the AI and server markets and they don't have a huge wafer allocation to burn on something, anything that can make them money. They were drowning in what, 14nm silicon they had to buy?

It's a different world than a decade ago.

The 7800xt has the right memory bus and enough memory bandwidth, but seems to lack the computer for the "xt" marketing.
As a follow up to their vanilla 6800 its a small but not insignificant upgrade.
Compared to the 6800xt, this is essentially achieving parity though a small energy improvement is also a nice touch.
Good value when compared to Nvidia offerings. But, kinda meh. I guess lines up with my expectations, though I was really hoping for some bigger performance numbers.

Gonna keep my 6800 for now in my PC. And Wife will make due with her 2060 since she plays a lot less games, and runs them all on at 1080p.

How did you read that into my comment??? :)

My point is similar to yours. I don’t have strong feelings towards any company, I just want a competitive market, and it sucks when one part cannot create competitive products.
I didn't misread your comment. I went off on a bit of a tangent and I didn't want to totally hijack the thread. I am just a bit frustrated with the GPU market.

It's been a disapointing three years or so, right when it was promising to really get good again as GPUs moved to modern node processes. It's like the stagnation of 5-7 years ago but they are doing it by choice rather than necessity... and the supply chain imploded AND then proved to both vendors how much we might actually be willing to pay. :/
