AMD 6500XT / 6600XT / 6700XT

Hence why I think they are clocked to the edge and us leaky silicon,which can clock higher. It will be interesting to see how much power the RX6700 draws,but apparently that is going to hobbled by 6GB of VRAM! :(

Yeah, 6GB is meh...

If the 6700XT is 3070 levels of performance i'm still interested, even at £430? Tho i'm much less enthusiastic about it.

If you look at the TDP on the RX6700XT its only 25W less than the RX6800.Hence I expect it to be leaky silicon clocked to the edge. It makes me wonder whether the RTX3070 will actually be better in performance/watt,as the RX6800 is the most efficient gaming GPU ATM.

That's a lot of power for an entry card, that'll mean some gamers buying this card will neeed to factor in the cost of a new power supply

You can see this kind of random logic applied because AMD's pricing strategy is just to price the GPU nearest to whichever Nvidia GPU it performs close to - so one generation the 70 series can be $200 and $500 the next. If the 6700xt matched the 3090 they'd price it at $1450.

In a way its kind of genius, they let Nvidia do all the hard work for market research and price setting and then AMD just copies them without the work going in - and then Lisa Su tells the shareholders "look we must be making good money cause we just copied Nvidia's pricing, their shareholders are happy so you should be too"
 
That might work in a pandemic and a mining craze, in normal times no one would touch AMD GPUs v Nvidia, that offer a far better feature set.

It doesn't say SAM enabled.



Ya but they are claiming its here.

95% a 6800, With 40 CU's and 2.45Ghz how?????????

I don't buy it, not even with SAM.

Actually, I do expect such results and they do look pretty normal as expected because the 6800 is a fail performance wise - it simply severely underperformed for what it really is.
Maybe bad binning, low clocks, low TDP limits, guess why.

But Navi 2X RDNA 2 has the needed IPC increase, so these results are exactly where the architecture should fall.

Why does it need an IPC increase? Compared to what? Nvidia?

3090 628 mm2 die, 10496 Shaders, 350 Watts
6900XT 520 mm2 die, 5120 Shaders, 300 Watts

Edit, what you're saying doesn't make sense, the 6700, 6800 and 6900 are all the same RDN2 architecture, they are the same IPC.

You do realise you're talking to the guy that thinks a gpu can be designed manufactured and distributed inside a day, right?
