gvarvWell, we are talking about people who thought that a budget 3060 needs 12 gigs of RAM... while the 3080 got 10... well played NVIDIA, well played!

• The 3080 desktop processor has a 320-bit memory bus. When it was made, only 1 GB GDDR6X chips were available (that's still the case now AFAIK), so the bus is populated by 10 of those chips for a total memory bandwidth of 760 GB/s. (The 3090 has a 384-bit bus and does double up the chips, using 24 instead of 12 placed on both sides of the PCB to get 936 GB/s of bandwidth. Not cheap and apparently a pain to cool - 6X is toasty.)
• The 3060 Ti, 3070, and 3080 mobile all have a 256-bit bus using GDDR6 (not X) chips, readily available in 1 or 2 GB sizes. This means you can have either 8 GB or 16 GB of VRAM; for the price of the 3080 laptops I’m not surprised they went with 16. Memory bandwidth is slower (448 GB/s on the 3070 and 3060 Ti, probably 384 GB/s on the 3080 mobile).  Keep in mind that the 3080 mobile is a GA104 like the 60Ti/70 desktop, not a GA102 like the 3080 desktop.  (also for trivia's sake - the 980 mobile also had more VRAM than its desktop counterparts - 8 GB vs the 4 GB 980 or the 6 GB 980 Ti!)
• The 3060 has a 192-bit bus with GDDR6, so its only options are 6 or 12 GB. Its bandwidth should be around 360 GB/s.

They probably would have loved to give the 3060 only 8 GB like the 60 Ti and the 70, but the way they designed it made it impossible unless you want VRAM bandwidth to drop once you start using all the memory like the Xbox Series X (or the GTX 550 Ti).  The GTX 970 had a similar problem for a different reason.

Granted it's still not great and Nvidia's decisions look illogical aside from pure profit, but it's easy to see the wall they painted themselves into.  I wonder how much the 3080's performance would drop if it was paired with regular GDDR6 and thus a top bandwidth of ~560 GB/s.

ENewt, the last time the 3080 FTW3 Hybrid moved, how many minutes did it go up?  Just curious since I'm eventually, someday, maybe, going to get hit by that queue as well... many moons from now, cuz I'm at 9:24 for that as well lol

Good evening everyone,
I was just wondering what kind of timeline am I looking at as far as getting a notification. 
My entry is 10/29/2020 @ 4:36PM for the RTX 3070 XC3 Ultra
TIA

gringorus
any one know how to check my queue position?

really want the 3080 but i'll probably have to take the 3751 , for now hope it drops today, since the last 3751 was "3070 XC3 Black 3751 10/29/2020 06:09:41".

HOLY SMOKES, you were so close!
I hope they catch you with todays drop!

first movement on that SKU in over several weeks.  good to see.    I'm still a minute out.... which most likely will be another couple months or more.     But hang tight!

To be fair, the 16GB on the 6800 that they're trying to compete with more is kind of useless outside of rendering work and the like.  There's no way the 6800 would be able to produce a playable frame rate on a game that would actually use more than 10GB of VRAM as far as I know, it doesn't have the throughput.
 
I do question why they didn't put the 3080 at 16GB from the get-go, or at least 12.  Is 10GB "enough" from my own experience?  Somewhat.  I've gotten to just over 10248MB of VRAM usage (actual usage, not just requested) in ONE game so far on my 3090, and that's at 3440 x 1440, so I can imagine 4K & bigger ultrawide/Super-Ultrawide resolutions the vRAM usage in some games is going to get up near that 10GB mark.  In Cyberpunk for example, with everything at the highest settings possible except DOF & Motion Blur being off (because I hate them), I'm only seeing 7800-8400MB of vRAM usage.
 
I can understand from a chiplet arrangement standpoint why they wouldn't want to go with the 16GB mark, because that would mean either double-density chiplets, which are more expensive, or putting some of them on the back of the card like the 3090 has, resulting in needing more of everything being required to have things "wired" inside the PCB for the front & the back... which isn't a huge deal, but it's still an increase in production cost.
 
Hopefully NEXT generation NVidia will learn these lessons, FINALLY, and put 12-16GB on the "flagship" mainstream GPU aka like the 4080. 

Just curious, do you muck around in VR or any VR flight sims?  I do punch through 12-14GB's regularly.

Not as yet... and that makes sense because VR assumably renders more stuff around you so it doesn't have to load as you turn resulting in lag or frametime spikes.

4K and AA all the way up on Modern Warfare Remastered, pushes 15Gb.

I’ve routinely pushed over 10Gb, once you go over 4K, ultra, and bump the AA up it’s easy.
