*** The AMD RDNA 4 Rumour Mill ***


Oh dear. If this is true my 3080 12gb might have to carry on a while longer (or I remortgage).
meh.... the 6800 XT has 20% more cores and yet its slower vs the 7800 XT, the 7800 XT is on par with the 6900 XT which has 33% more cores, how many cores a GPU has is irrelevant, RNDA 3 is about 30% faster per core vs RDNA 2.

We all knew AMD wasn't going to be doing high end GPU's for at lease this generation if not more, = to a 4080 or 5070, which would put it 50% ahead of your 3080, not bad, it all depends on price, the 5070 is going to be £600 or £650 or £700, probably £650, if its £550 it should do well, if its £500 it will do really well.

At 7900XT and better RT for £500 I think they'd sell like hot cakes in the current market. All depends if NV can bring out 4070Ti performance for a similar price...

The fun thing is with a few tweaks to the 7800 XT is near enough on par with the 4070 Ti in raster.
 
Where are people getting the rumors where the 8800XT is going to equal a 4080 as what I'm seeing is that its rumored to match it in RT not performance. This is a wild rumor as a 8800XT would gain 50% in RT over a 7900GRE to match a 4080.

Ps5 pro has like double the CU count of base ps5 but they claim it has 300% higher RT performance. That's supposedly going from rdna2 to 4's RT core

So if you have a GPU going from 3 to 4 with the same or slightly less CU's then 50% faster RT doesn't seem strange

Yeah I was (happily) corrected earlier, I misread the article. Looks like roughly 4080 performance, which would be enough for me to upgrade but like you say, it depends on the price really. If it can trade blows with the 5070/ti while being cheaper then it's a winner. 5070 looks like the sweet spot, the 5080's VRAM is a bit of a weakness until they release the real one in a year.

In all honesty though, really hope they finally deliver this time round. They just need to get the pricing right on release and not try and milk their diehard fans before dropping the price a few months later.
 
RNDA 3 is about 30% faster per core vs RDNA 2.
Wildly incorrect.

In RT possibly, no way in raster from a small 220W chip.
You might be surprised, the 7800 XT with its 4 chiplets is near the same size as the RX 6700 XT (335mm vs 346mm) and 47% faster. Thats only from 6nm to 5nm, here we are going from 5nm to 3nm.

If the rumour was the 7800 XT was 3% larger than the 6700 XT and near 50% faster you would have said the same thing, understandably so but it is what it is, so its very possible. :)

Also 225 watts vs 250 watts.

Is humbug not saying on paper the cores are 30% faster. I don't think he's saying that equates to 30% more fps in games. Perhaps a misunderstanding here.

What i said was this.

I'm probably a bit off with that but not far, its not a good way to measure it and had this be the point i was making i might have gone the extra mile to find a better way. My point was simply this what i said in the context that was edited out and highlighted here in bold, people quoting me out of context to start an argument i never made with me it really tiresome, which is why i ignored it. :)
 
The only way this is going to be a big seller is if it's priced low, £500+ IS NOT LOW!
Even £400 is more than most pay. The sweet spot used to be £200-250, now it's probably £250-350. AMD also need to have enough of them ready to sell which will not happen so it will be 6 months after release before most can get one.
