AMD Navi 23 ‘NVIDIA Killer’ GPU Rumored to Support Hardware Ray Tracing, Coming Next Year

Agreed about the 3090, I really think this was done for the fanboy warriors to state "well nvidia has the most powerful card so ners" - its just...I dunno...so unnecessary? Its like a massive flex and nothing else.

Couldn't care less of AMD can challenge it or not. 3080, yes.

"Around 47 per cent of the entire area is gifted to the 56 AMD RDNA 2 graphics compute units (four of which are disabled in order to allow chips with minor defects to make their way into production consoles)"

Its probably more than that with the IMC's and IO, lets say it as much as 60% of the die.

360mm2 X 0.60 = 216mm2, that's the size of the 56 CU GPU, you don't need to double the IMC's and IO again so add another 180mm2 to double CU's only = 395mm2 for a 112 CU GPU + 42% = 159 CU's, 395mm2 + 42% = 560mm2

Roughly 550mm2 for a 160 CU Big Navi

That's 28 Dual CU clusters (56 CU's) Big Navi is 3X the Series X

Rich coming from you

Also, the topic is in regards to the "nVidia Killer" -- talk of the nVidia cards that are scheduled for execution is very well on topic.

No, they are not.

As far, we will have two cards, n21 and n22 released in 2020, the n22 will beat the 3070 and match the 3080 with some clockspeed increase $549. Best value card in the set.
Its the Nvidia Killer for sure. No one sane would buy anything else.

The n21 is still not much known about and we may have a 3090 match with some additional clockspeed but the cost will also reflect that. still the better option vs various 3080ti/s etc...

Looks good for amd and next generation will be really interesting

If that Dual 80 CU Big Navi really exists it should be referred to as Leviathan Navi.

The 1080Ti came almost a year after the 1080 if I recall it certainly wasn't a few weeks or months and it was at least $100 more for +3GB vram and more shaders.

I don't disagree but iirc the 1080 was sold as the top card ie customers weren't expecting to have to trade up in (less than?) a year because their card wasn't the flagship card of that generation. If I'm not remembering this correctly I'm happy to be corrected

Yeah, depending on size of the case you could do with a <200w card once undervolted etc.

Hopefully.

IF they did go with an MCM,it would make more sense if they went with maybe a dual 56/64CU die,ie,for yield purposes.

Rogame said HD4870 vs GTX260. So it could be AMD is going for a relatively high performance smaller die?

I think this is where they'll aim. Higher yields, more profitable and more potential customers at a more affordable price. Maybe even use the consoles as the benchmark rather than Nvidia. "Buy this card for $XXX and get performance equal or better than on console" whilst not costing the earth.... maybe.

Yea Intel has an issue with heat and design on old nodes.
No wonder meme exists.

However as I play at 1440p 32 inch screen 144hz, love it and amd bringing a Nvidia killer at $500 segment seems too good to be true but I understand the uplift will be so great I will overcome it. soon October and a long winter kinda with a lot of fun gaming to have.

I would love to see AMD finish off Intel and beat Nvidia in this round all in one go but while i think Intel are done when Zen 3 hits i have this nagging feeling that while AMD could make a 3090 Killer and have probably built and tested such a GPU they will take the cost effective rout and make a smaller competitive GPU.

Again, Intel are done in the DIY space, that battle is already won and Zen 3 will just be the death blow, i think now AMD should just make the best GPU that they can, right now AMD need to send a message, that message is: we are not second best, we can beat Nvidia if we chose to.

Yup this 3900x im running is a freaking Beast in gaming production downloading porn

:]

All my mates are on Ryzen now after iw upgraded theirs systems

think i got it.. theres no easily identifiable back plate in the 3080 design.. should have seen one of those unboxing videos

I don't care really if AMD beats Nvidia's 3090. That GPU is so uninteresting. 350 watts of furnace power, no thanks. I'm much more interested in a GPU that gives me around 80-100% of my Vega 64 for cheap. My Vega is already doing 1440p fairly well, just need that extra oomph to the lows above 65-70, and being able to also run high/ultra-high in next-gen titles would be sweet.

If a card is better performance than the 2080Ti and is sensible price it will be a nice upgrade from my vega56. The 5700XT was not big enough jump so I am confident they will deliver on this. Bonus is the green brigade costs are sensible, so it makes AMD's cards pretty much be less too (win-win). Thanks Jensen!

Then they can use the CTR to get a further % performance for some % power savings!
