Okay  I just got  what is one of the fastest  ZEC mining gpus in the world  a Nvidia AORUS  1080 ti

It does over 700 h easy  with good power numbers.

It has 11gb ram

and the

"Pascal" architecture, the 16 nm "GP102" silicon.

https://www.techpowerup.com/reviews/Gigabyte/GTX_1080_Ti_Xtreme_Gaming/

So  how far can  gpus go before they hit a wall   

10 nm most likely could be a wall  of sorts  we could be there  for 2 or 3 years

if that happens  does  nvidia   expand ram to 16gb?  or prehaps 24gb?

This is not AMD vs Nvidia.

 I will delete    posts like that
What I want is ideas on  gpus over the next 2-4 years.
I think  we will sit at 10nm  a long time
which means  ram  increase and faster ram  may  be the future for gpus.
Any ideas or guesses are welcome.

I say eventually, it will come down to optimization and power consumption (performance per watt). Because there is only so much speed that a chip can push.

Look at intel for example, as their CPU evolves, their speeds are always like at a wall, like 3Ghz, 4GHz, and etc. You don't really see them releasing a 5Ghz+ CPU as they evolve. What they do is optimize their CPU and increase the core counts for multi-threading.

So maybe, down the road once that wall is hit, I say they are going to be like dual 1080 ti in the same watt usage and size as today's single 1080 ti for example.

I think we need to see were VEGA goes.... I think in the near future the new cards are just gonna be optimisation then may be dual ship cards ? ( as they're more and more efficient they will produce less heat then may be 1 ship will run so cool that you can do a dual gpu card, like a "sli integrated" card  8) )

isn't nvidia going to release new remake of their pascal line-up? i see they are called 2070 and 2080, maybe a monster called 2080ti also? all the website say that the specs show that the gpu are 10% faster than current pascal, could be worth to wait for that before buying, but the real game changer will be volta for nvidia and high end polaris for amd, still a long way to go for that

You can already get a TitanXP that beats even non-reference 1080ti's pretty easily :D

Titan Xp - 3840 cuda cores, 12GB GDDR5X, 547.7GH/s memory bandwidth
1080ti   - 3584 cuda cores, 11GB GDDR5X, 484GH/s memory bandwidth

a new even stronger gpu from nvidia, how greedy, i'm curious about the hashrate on zcash, should be near 800 sol, which is insane, but still the price is too damn high even for that hash

You guys are forgetting what R9 nano did with single 8 pin and 28nm manufacturing process, those cards with more optimization and 14nm process could provide amazing efficiency,

If you don't mind, could you expand upon the good power numbers portion?

I was thinking about picking one of these up for my gaming rig thinking I could mine ZEC during off-hours (when I am not gaming). However, I would like a little more information on the cost of operation. Since I wouldn't have the benefit of multiple GPU's to offset the system (mobo, cpu, etc.) wattage overhead, I need to work the numbers a bit to see if it would be a viable choice.

1 card with an i5 6400 t cpu on a biostar z170 board and an evga 750 p2 psu   can do 700h using 220 watts at the k-a-watt meter.

I am more of a rookie with nvidia  so the 3.182 h a watt    at the wall can be tweaked better  700 h  is about  130 usd a month 24/7  doing zec

10 cent power would cost  about 18 bucks a month

so 1 card will profit you close to 110 a month  mining 24/7 

settings
    70% power
+125 core
+300 memory
fan at 75%

In 2-4 years...

HBM low cost version will be out for mid-range

HBM3 will be out for high end

HBM chips are "stacked" and installed on the logic board next to the cpu, which makes compact cards possible (such as with r9 nano).  As well for better speeds.

https://cdn.arstechnica.net/wp-content/uploads/2016/08/hbmchips-800x450.jpg

Currently hbm/hbm2 stacks are expensive to manufacturer but "hbm3" and "hbm low cost" will be much cheaper to produce.

You will see high end hbm3 cards with as much as 64gb on board ram and speeds in terabyte range.  One of the advantages of hbm3 is double density dies for greater memory capacity.

They will also have lower energy consumption.

I think this will probably be the future and Samsung is sinking a lot of money into this technology.

Thanks I was looking for info like this.... 

it would be neat to see a powerhouse like a nvidia 1080 shrink down to a half height half length profile. 

the zotac mini  is fairly small  https://www.newegg.com/Product/Product.aspx?Item=N82E16814500414&cm_re=zotac_1080_mini-_-14-500-414-_-Product

Form Factor & Dimensions
Max GPU Length
211 mm
Card Dimensions (L x H)
8.31" x 4.92"
Slot Width
Dual Slot

Nice, Zotac mini is half length for sure !!!  if its half height and takes a single slot space then it would be perfect!!  maybe by year 2018 it can happen!!

just for kicks, i found this and i think its the smallest and some what powerful videocard for Nvidia ..   its a joke compared to today video cards but it a start..

this card is small  and mines  about 11mh for eth

https://www.newegg.com/Product/Product.aspx?Item=N82E16814150788

nice!! I have the amd 360 version of that . is there a Nvidia that can match that?? for small form factor or even from AMD in half height??  I really think that is the future , half height half length cards!!!

Single slot high end cards are not that popular , gamer chillings lots of money need some big bad ass cooler with lots of flashy colours.

Here is single slot 1070 GTX , same can be done for 1080 but no body will buy it .

Even though your 1080 Ti does 700h/s, it costs $700. A pair of old 7970's costing <$200 does the same speed. They would use double the watts but with decent electrity rates it would still end up being more profitable in the long run.

My profit model includes:

1) sale of gear.  I have customers waiting.
2) density I have limited space.
3) cost of power  my winter rates adjusted for using the heat are 9 cents my summer rates adjusted for extra cooling are 20 cents.

I am pretty happy with the price  as I can do 700h for 210-220 watts  1400h for  420-430 watts

So during winter rates  which end June 1  the pair of cards cost me 31 dollars a month about 1 dollar a day

during the summer the pair of cards cost me  62 dollars maybe 65 dollars a month  say 2.05 a day.

1400 h is about 9 usd a day in earnings.

so I make 8 bucks a day in the winter and 7 bucks a day in the summer

By the time it is Oct 1    and back to winter rates  I should be at  840 + 400 = 1240  cash back on the 2 cards.  I paid 1484 for them so on OCT 1 they will be at 264 net

I will be selling them and should be able to find buyers for them  at 400-500 each   so  900 - 264 = 636 profit   on 1484 invested in under 6 months.

Hi Phil,

What software do you use to mine? I'm keen to try my hand  at mining alt coins.

Edit - question 1  answered I read your signature

Also, is it feasible/possible to slap one or two of those into a machine which currently acts as a home server and keep its current function and just use the Gpu to mine?

Okay  amd  is smOS

smOS is a dedicated linux  you lose  the pc  for other stuff


nvidia is


EMBF_     in a windows 7  pro  box  .    If you mine zec the pc  can do other shit.

the better the cpu  and 2 sticks of 8gb or more ram in the server  you can run the nvidia in the background.

 https://bitcointalk.org/index.php?topic=1707546.0   



If you want amd in the background mining  you need a windows box or a linux  not dedicated to smos

there are at least 4 dedicated linux setups

nvOC -- for nvidia

Thanks! I've got an oldish I7 with 16gb ram and a gazillion hard drives, a 1000w PSu Windows 10 and no Gpu, primarily use it for Plex - I am terrified of reloading an OS for fear of losing 20+tb of media in my clunky old raid setup

I'll try an Nvidia in there - just need to check that I have a pci slot that doesn't have a raid card and I could be in for just the price of the Gpu

yeah  if this is the case  you could  try a cheap  nvidia  like a 1060 or 1070

but my nvidia knowledge is limited  as to which 1070 or 1060 would be  a good one

Would that 1080ti work in that rig. 700 is cheap compared to building a dedicated rig

the smaller zotac with the blower would fit  the aorus  1080 ti is a beast


https://www.amazon.com/ZOTAC-GeForce-Founders-Graphics-ZT-P10810A-10P/dp/B06XDN4TXK/ref=sr_1_1?

 And lower clock rates than the 1080 ti, it's quite a bit more even on actual performance than you think.

 For reference - the Titan X Pascal PREDATED the 1080 ti - the 1080 ti is basically a "one section disabled" version of the same GPU (partly to help with yield) that clocks ballpark 10% higher to get to the same total power usage.


 The Zotac "mini" isn't actually all that short - it's almost identical length to my Sapphire RX 470 blower-style cards, works out to ballpark an inch shorter.
 It does appear to be the smallest 1080 model at this time though.
 
 The Gigabyte "ITX" single-fan GTX 1070, THAT is a short card. 7" long almost exactly COUNTING the "flange" on the mounting bracket.


 I don't see any possibility of anyone making a low profile 1070, much less a low profile 1070 - but I AM supprised that nobody makes a 1060 3GB low profile, or that the ONLY RX series low-profile is the AMD WX-series workstation varient on the RX 460.
