It's going to be another gen for me I suspect.
2X RX590 performance at 300ish euros won't happen anytime soon.

2x590 appears to be somewhere between 3060-3060ti in many games so we're pretty close already
edit: or do you specifically mean AMD? - I would have preferred an RX6700-6800 class card this time round but ended up with the 3060ti due to availability and pricing

We're still 100€ above that, not exactly bargain prices.

Ah ok, sorry I hadn't noticed you were in Italy and have no idea what prices are like there, 3060 starts around £320 here (€370 - also thought the euro was closer at the moment so fair point!)
I suspect we won't get better prices until january.
I'm long due for a full replacement anyway, black friday deals were actually worse than a couple weeks before so my i7-3770k is going to actually have it's 10th birthday.
I don't quite agree with this. The specs just don't match up to those gains.
| N21 launch products | N31 | Cut N21 (6800) | N32 (7800XT) | N22 | 1 SE Cut N32 (7700XT) | N23 | N33 (7600XT) | |
|---|---|---|---|---|---|---|---|---|
| ROPS | 128 | 196 (+50%) | 96 | 96 | 64 | 64 | 64 | 64 |
| CUs | 80 | 96 (+20%) | 60 | 60 | 40 | 40 | 32 | 32 |
| Bandwidth | 512 | 960 (+88%) | 512 | 640 (+25%) | 384 | 480 (+25%) | 256 | 320 (+25%) |
| Top vs Top Delta Per AMD Slides | +70% (6900XT vs 7900XTX) |
So Top N21 vs Top N31 is similar in clocks and is getting a pretty good uplift vs the 6900XT.
For the rest of the stack while it is not looking as though much more than bandwidth will change I expect core clocks to be quite a bit higher. If AMD can achieve a ~20% clock bump and their 17% per CU IPC gain is accurate that means there should be about a 40% increase in performance from the same RDNA 2 config. We also saw a ~40% going from 5700XT to 6700XT which had the same CU and ROP spec so AMD have form for this through a combo of IPC and clock increases.
A 40% increase from 6800 would be 7% ahead of the 6950XT @ 4k which is bare minimum for 7800XT IMO and I could see AMD push the TBP and the clocks of the 7800XT to eek out a bit more here so they can get a 30% gen on gen gain over the 6800XT.
A 40% increase from 6700XT would be around 6800XT performance for the 7700XT @ 1440p and a bit behind @ 4k
A 40% increase from the 6600XT would be around 6800 performance @ 1080p and between 6700XT and 6800 performance (3070Ti ballpark) @ 1440p
So not terrible gains across the stack as everything shifts up a tier. Not as good as the 6900XT -> 7900XTX gain but the reality is the 6900XT was always too close in performance to the 6800XT to be worthwhile so that gap did need to grow a bit.
Now in theory AMD could do a 2nd N31 cut as a 5SE 70CU 160ROP design with 5 MCDs and 20GB of ram but I don't see that happening unless they increase the price of the x800 XT to say $750 and then make full N32 a 7800 price at say $600 but even then I just don't see it. I expect AMD will just push the clocks and TBP of top N32 to 300W if needed to get that 6800XT + 30% performance because it looks doable with enough clock speed.

AMD seem to be capitalising on value at the moment and really beating NVIDIA up on prices. Although I already spend my GPU money on a monitor, I'm still awaiting the tests for the 7900 with interest. Who knows?

The way I came up with my numbers is I took AMD's slides where they show the 7900xtx performance vs rdna2 and then scaled the other rdna3 GPUs off off that based on core count. For example if the 7900xtx is 80% faster with its 96CUs then I estimate 60CUs is 10% faster (because using a 6950xt as the 100 baseline, +80% is 180 and 60/96 * 180 = 110, 10% higher than our 100 baseline 6950xt. And then I take the 6700xt's performance on TPU chart compared to 6950xt+10% to get +60% over the 6700xt
As I did say though, my calculations assume that each extra/removed CU has an equivalent performance gain/loss and I also assumed the clock speed on all rdna3 GPU is the same as the 7900xtx. I have to make these assumptions because until we have multiple RDNA3 models in the hands of reviewers I don't know how the CU count scaled with framerate and I don't know what clock speeds the unannounced cards operate at; all I have to work with is a rumour going around that rdna3 has the same clock speed ceiling hard limit as rdna2 and the 7900xtx looks like it's already at or near that ceiling so I don't think the other models have higher clocks for now

Seeing Vapor-X making a return after such a long time really hit me with the "wow...it's been such a long time...I'm really getting old"

Remember when Cross Fire was a thing?
That's 80% scaling.
Sapphire Radeon R9 290 Vapor-X 4 GB Review
Sapphire's R9 290 Vapor-X comes highly overclocked out of the box, matching the R9 290X in performance. The card's triple-fan, triple-slot cooler manages temperatures very well and offers a unique feature: you decide whether the card idles with one or three fans running, which lets you focus on...

I thought the 7900xt has the same power requirements as the 6900xt?
Why would they need all that extra stuff unless they plan on overclocking it? Lets see what we get with the overclock.

Yep loved the principle. Liked the idea that you could buy a card initially, then a couple of years later pick the same one up second hand and add it. Although most games didn't benefit there were the odd few that it worked OK on.
Having overkill VRM’s these days is equivalent to having an ‘i’ after your car model in the 80’s. Mostly marketing spin to justify the price.

Bad example
Take the classic Gold, the Mk1 1.6 GTI had a 1.6L fuel injected engine developing 110 BHP, the 1.6 GT had a 1.6L carbureted engine developing 75 BHP.
The "I" was Injection.

Oh I know what the ‘I’ was for and you are right it is a bad example
I just mean, it’s the done thing now. It’s not actually required most of the time. So many motherboards and GPU’s have insanely overkill VRM’s. Seems like it’s mostly marketing to justify the price or something. Or look good on the box, or an unboxing video on YouTube haha.

Is it true there’s a 7990 in the works?
