They can quite literally double the size of the raster core whenever they want, they're just choosing to take pity on Nvidia my dude.

If going by 7900 pricing it should be priced well performance we don't know yet . It's like the only option open to me so will see

They didn't really show much if any raster performance charts?

The 5NM core is smaller than the TSMC 4NM core used in the AD103 based RTX4080 16GB. It wouldn't surprise me if yields are better on Navi 31 than AD103. The memory chiplets are tiny.

DisplayPort is backwards compatible. So you'll only "need" a DP 2.1 monitor if you want to use that bandwidth.The funniest part of the presentation was when they said unlike out competitor you won’t need a new power supply (you don’t)
Few minutes later : you will need a new monitor with display port 2.1

Calling it a blanket generational gap is clearly hyperbole... unless you add on " in Raytracing".

Lol
Hardware Unboxed also said it’s more comparable to 3090Ti
Lmao doesn't that cost more new also using more power

I wouldnt rule it out, but the handy thing even with the sizeable price difference between the 7900s & 4090s means the margins for scalping must be limited because demanding £1500 is gonna force folks to retailers where they have 4090s sitting on shelves already.
There was no limit for day1 4090s, but the cap for a 7900xtx is surely around £1500 otherwise you'd buy the more powerful 4090 and a fire extinguisher.

its a divergence.. at the moment the 2 cards cant be compared because youd get a completely different picture depending on what you choose
- pure raster
- raster + dlss/fsr
- raster +rt
- raster + rt +dlss/fsr
even dlss/fsr settings are not comparable given how the internet doesnt stop arguing about iq differences
my estimate is nvidia is a couple generations ahead of amd right now because they have chosen to move away from traditional raster performance, nothing was stopping them from filling up CUDA cores to the brim or using the die space for more ROPs
Hardly any games have FSR now after a year. Almost all new games have DLSS. For this reason alone I'd choose Nvidia
Yeah shame I'm priced out of the 4080 16gb
Sorry for not wanting to trawl through the last dozen pages, but have they revealed performance numbers (even if they're AMD's own numbers).
I've just started catching up so wanted to know if I'll eventually come across it in some of the media coverage.

The XTX is still way more reasonably priced than the 4090 and if it comes within 85% of the performance then I'd call that a win

Mostly for RT, not much for rasterization (which is still the vast majority of games).

Hardware Unboxed reviewed both and said the RX6950XT matched the RTX3090TI:

So how does an RX7950XTX only match an RTX3090TI?
Nvidia is at the reticule limit for TSMC 5NM now. AMD isn't - the core die is literally half the size of the AD102 on a slightly worse version of TSMC 5NM. The memory dies are tiny and made on a lagging node.
The next jump to TSMC 3NM won't be as big as the jump from Samsung 8NM(which was a 10NM process node),so Ada Lovelace looks big because the transistor jump was much bigger than normal. If anything AMD has far more room to improve performance over the next few generations.
Now if Nvidia can move to their own chiplets soon then it might be different,but otherwise they will face a scenario like Intel is now. Intel has to throw die space and transistors at the problem.
Edit!!
Another thing - if AMD is comparable in performance/watt or even better than Ada Lovelace,that means the interconnects are more efficient than I expected. In Zen1 the IF,was a major contributor to CPU power consumption.
