NVIDIA 4000 Series

There will be refreshes along the way

rumours say Nvidia is using a memory controller that has support for G7 vram, so as soon as G7 modules are available they will start introducing Supers with G7 memory

I'm going with typical of 30% improvement and £850-900 fake msrp for 4080 with 12GB. Real Street price £1250-1500 for the AIBs. This all on a 103 chip not even 102. Now we know why 103 chips this gen were created so they can also be pin to pin replacements.

AD103 chip has 256Bit bus so you will end with 16GB VRAM, Ada Lovelace GPUs should use the new 2GB GDDR6X chips from Micron. RTX 3080 had only 10GB because they were using 1GB GDDR6X, there was no other version. Meanwhile GDDR6 from samung has 2GB chips since ages and RDNA2 is using them.

With 2GB chips you can make this
AD102 384Bit 24GB or (48GB in clamshell mode double sided PCB)
AD102 320Bit 20GB or (40GB in clamshell mode double sided PCB)
AD103 256Bit 16GB or (32GB in clamshell mode single sided PCB)
AD104 192Bit 12GB or (24GB in clamshell mode single sided PCB)
AD106/AD107 128Bit 8GB or (16GB in clamshell mode single sided PCB)
 
Well, the RTX 3080 FE (at stock settings) uses about 45% more power than the RTX 3070 FE.

If the RTX 4080 and 4070 follow that pattern, you'd expect the RTX 4070 to use approx. 330w of power (assuming 600w for the 4080). So, the RTX 4070 will probably still work on a high quality 600w power supply.

The other important bit for many, is power consumption. E.g. Will a RTX 4070 even run on a decent 600w power supply? I'd guess it will push it to it's limits.

Wouldn't be surprised if most people have to upgrade their psu to a design which meets the new specs in order to manage power spikes on the higher class cards in the 4000 series. I use Radeon chill to try and keep my gpu under 200w, I am not going anywhere near a 4000 series that uses 400+ watts

I run my 3080 at up to 300W, which I'd rather not raise with new GPU as I'm sure the heat output would be uncomfortable. That said, I still grabbed a 1kW PSU just for expected spikes.
 
My 3080Ti pulls well over 400W. My entire racing sim (PC, wheel, transducers etc) pulled enough power to make my 900w battery-backup-UPS throw overload beeps when I was racing. That's when it occurred to me that my 1kw power supply would never be able to provide 1000w of power while connected to that battery-backup. I live in Florida and the summer storms bring a lot of power flickers, so battery backup is important to me.

I ended up getting a 1500w Cyberpower Sinewave batter backup unit. I plan to skip the next gen because my current setup does everything I want it to do, but maybe I'll get the itch anyway.
 
You can undervolt the cards a bit and take some of the watts down. I couldn't get the card I wanted which was ASUS 3070 2.5 slot cooler but I was lucky enough to get a 3070 FE at MSRP and I have been impressed by that cooler. It's just about acceptable noise for gaming, having my 3x 140mm intake fans ramp up a bit also helps. I just hope I can get the quietest 4070 or 4080 card. Although I think prices will be an issue, but on the flip side of that the 3000 series card will hold their value so that is an option to offset the cost.
 
Gets really uncomfortable playing in the summer end up not playing at all yeah houses are designed to keep the heat in here this is with 3080 at 300w

Great for winter though

Seems like 10-12GB for 4080 and 24GB for 4090.

This cards won't be readily available untill January. So for those people who think they're smart "holding out" for a 40 series card. Have fun basically waiting a year with a completed build :cry:

I'll be going for FE again if can't get or AIB is priced much higher :p paid £649 3080 the ones that paid £1k+ and wanting to upgrade will take bigger hit :eek:

Looks like it will be a repeat of the Ampere lineup re vram, but this time we'll also get a 4070 with 16 GB, which is likely to be the best all-around option.

There's no way Nvidia would try and pull the old VRAM scam again is there? They'd never do that surely? I mean it's not like anyone was fooled last time right? - £800 cards with 2017's VRAM?

Nvidia wouldn't dare and no-one would defend it anyway...

Oh wait what am I saying?

:cry:

Well I had a 3080 FE in 2020 so that is old news now. Sold it for around 3 times the price and picked up a 3070 FE and now I am holding out for a 4070/80. As soon as I grab an FE of one of those will sell my 3070 for the price I got it with ease :cry:
