1390 more to set up
i'll get along with your analogy. $ 1390 more.. for people who think 4 card is a hell lot more easier to manage than 12 card rig? for people who are thinking of higher resell value? for people who think they can have more coins to mine(nvidia has more options than amd)? is 1390 more worth it?.. for me yes...I was able to travel the previous years while those rigs are mining hehe one 4 card rig vs three 4 card rigs. and I forgot to mention if you use simple mining it is 2 bucks a month for your rig and 6 for my 3 rigs so that is 4 x 12 = 48 a year in savings. Yeah a lot depends on how many rigs you want to do. But 1390 price difference means it is not a killer of the 5700xt. both cases you get 600mhs one case is 1 four card rig at 1000-1100 watts at cost of 6200-6300 usd one case is 3 four card rigs at 500-550 watts each total of around 1650 watts. at a cost of 4800-4900 usd If rig density is an issue you may want the 3090. If cards keep turning a profit the 3090 is pretty good. If it all crashes you still have resale on the 3090 But my point is to argue that the 3090 crushes the 5700xt is simply not the case. Like I said I may buy 2 of them for my thread rippers.

miner software optimization might get 3090 to 150mhs...hopefully ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) No, Eth is memory bound, 3080 and 3090 have the same memory type and speed so the minor difference we will see would be due to 320 vs 384bit bus width. And this isnt on-die HBM, dont expect 90+ on anything. 1080 is 35mhs 1080ti is 50mhs that's 42.8% difference between 1080 and 1080ti, both gddr5x Umm ... the 1080 was a GP 104 with 256bit bus width. The 1080ti was a GP102 with 352 bit bus width, thats where the hash increase is coming from. That, and better binned memory that can clock higher. 3080 is 100mhs (there is a post that says 115mhs at 300w) if you do the math of adding 42% of 3080 to 100mhs that's 142mhs.
now nvidia says 3090 as titan like(they phased out titan, this is the new titan), if 3080ti is not released yet, then 3090 is better than 3080ti
if 3090 is better than 3080ti, then 150mhs is not impossible.
I dont think you understand anything about hardware, hash-rate or how the two correlate. I recommend some more reading.

I dont think you understand anything about hardware, hash-rate or how the two correlate. I recommend some more reading. Even if the 3090 does 150mh it will need 220-230 watts to do it. And it simply is not a lot better than amd 5700xt for eth mining. If a 5700 xt does 50-52 mh at 125-130 at the wall and the 3090 does 150 mh at. 230 at the wall it simply does not have a huge edge. also I don't think it will do 150 at 230 watts. more like 130 at 230 watts. but I consider buying one as soon as possible just to benchmark on my threadripper.

My 5700 XT Gigabyte does 54Mhs exactly, consuming 135 from the wall Of course there's room for improvement for 3090 and Nvidia another cards with miners and drivers, but I don't see a huge leap to kill older generations of cards, since polaris it's almost the same, a good gain on hashrate, more efficiency, but not overkill cards People still use polaris cards to mine In my country will be difficulty to buy any new generation of cards with a reasonably good price

That, and better binned memory that can clock higher. yeah, that means even 3080 and 3090 both have the same type of vram. other things can make the the other (3090) more faster than 3080, they have different bus width too. I just said both have gddr5x but the other one is 42% faster, the statement itself implies that there are other factors too. well you just have to read english more buddy. about "simple mining", i'm using windows 7, i heard there are issues with windows 10 about windows reserving 1gb of vram so if your gpu is 8gb, mining will be 7gb effective. with 24gb or cards with 16gb and above (amd and nvidia future cards). that won't be an issue any more, maybe i'll do windows 10 mining starting year 2023-25 hehe

I can get four rx 5700 xt for that with maybe 50 usd change. i.e. 200mh for 1605-50 = 1555 I can get six 5600 for 6 x 277= 1662 and get 60 in rebates or 1602 cost for 240mh so 3090 maybe 150mh for 1605 5700 maybe 200mh for 1555 5600 maybe 240mh for 1602.

we are the pilots of our own gpus, like pilots of fighter planes. sometimes you can make a good killing with cheaper gpu, sometimes you can make a killing with better gpus. my 390s and 480s were defeated in profit by my measly core2quad processors mining pascal coin. I even remember nvidia miners watching in the sidelines, while amd miners are happily mining ETH since amd users got the edge at that time ...280x's hehe what you all are comparing is ETH, again.. we all got out there mining many coins. nvidia still has more options to mine, more options = more opportunity for profit. more opportunity for profit = more chances of ROI. you ROI = you don't care if the GPU is expensive ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) I'm not saying the most powerful card is the answer because of "density", most powerful and most expensive gpus should meet the "criteria" for it to be used for "density purposes" (example 280x is better to own than 290x at that time....and 1080ti is best to own in its time too) and there's..personal preference, i'll repeat.. if you think you can ROI it, then why not? here is another example mining profits in 2019 is down..who is buying tons of radeon vii? hehe now they refresh newegg page several times daily LOL. if bull market is coming with full force then we ROI all our gpus be it 5700xt or 3090. remember when home miners cannot max out their mining rooms because rx 470 4gb? LOL.

I think the 3080 at a cost of $699 doing between 80 to 115 mhs on eth is more attractive than the 3090 at a cost of $1,499 doing 115 to 150 mhs on eth.
I personally don't see the 3090 doing 150 mhs and feel the roi is going to be significantly longer than the 3080's 10-12 months. If the 3090 ends on the lower end of eth performance your looking at potentially 2 plus years before it's paid off. For me I can't justify the difference in time to roi.

I'm thinking of selling my now 2 gen old GPUs. I checked sold listing on eBay as of yesterday and averaged the selling prices for the last few days.
It looks like the going rates are better than I thought. (I would never pay the below prices myself) Here's a breakdown of what I have that combined does around 2,100 MH/s on ETH:
25 1080Ti @ $380 = $9,500 1 1080 @ $300 = $300 14 1070Ti @ $260 = $3,640 16 1070 @ $194 = $3,104
So a grand total of $16,544 less eBay 10% = $14,890. But a more realistic net is probably around $10k
2,100 MH/s is about 23 3080 GPUs (assuming 90 MH/s) @ $699 = $16,077
My current mix of 1000 series cards consume right around 8,000 watts
23 3080's would drop that almost in half to 4,600 watts (assuming 200 watts per GPU)
I guess another option would be to pickup 40 5700s @ $350 = $14,000
The 5700s would consume 5,200 watts (assuming 130 watts per GPU)
My power is essentially free since I have 50kW worth of solar panels that produce enough kWh to keep the mining rigs running 24/7.
Dump my 1000 series cards while they still have some value, or just keep mining with them until they die? What would you do?

Here is the issue with eBay. A wise miner once said "The best time to sell mining equipment is usually when its the highest chance of getting screwed" it might of been phil if I recall correctly. The reason why is because they usually side with the buyer and what happens is people buy ASICs or GPUs on eBay. Then shortly after the difficulty can go up or price can go down and it might not longer be profitable and they will just open up a Paypa dispute saying "GPUs are not as described" and you will have to accept the return and sometimes they bill you for the return shipping. Best is to just sell it on FB marketplace or Craiglist and get cash instead. Hence no refunds possible.

free power means you need to have the highest hashrate as possible. x2 of your current hash rate is x2 profit the earlier you start mining with newer cards the earlier they ROI. keep them (old cards) running while adding newer cards, as you reach the maximum electrical capacity sell the older cards- preferably during ETH pumps like if it pumps to 500, buyers will appear hehe. will not recommend cards since 3080 is not out yet and we have not seen more info about it. besides running those many gpus i believe you already have an insight for your next ideal setup.

3080.. remember free power, 100mhs ETH is very good.. when near full capacity, then start looking for more efficiency or higher hash rate algo coins. 1080 and below, sell ASAP, they are dead when 3080 hits the market. I would hesitate from buying 1 year old cards that will be outclassed by cards that will come out next month LOL 3080 vs big navi.. big navi a bit better at efficiency or big navi better at pricing, the profit for using the cards 1 month early justify the "price difference"?..if yes then buy nvidia.

Do we yet have some definitive or reasonable numbers that show effective power usages? I've seen estimates but nothing more than that at this stage.

If I had a ton of 1080ti's and no better gear I would put some up for sale. I would put some of the sales on the side for the 3080 or 3090 I would buy this card now. https://www.newegg.com/msi-radeon-rx-5600-xt-rx-5600-xt-gaming-mx/p/N82E16814137571?I tried more then 9 amd models I like this one the most. I would try to become. ⅓ 1080ti ⅓ amd 5600 ⅓ nvidia 3080/3090 once I reached that goal I would sell the remaining 1080ti's and look at the big navi card or the 3080/3090 to put the rest of the 1080ti sales money into. For me and my team we are 12/13 1080ti 1 1080 1 1070 4 1660 1 1050ti and 25 new amd 5500,5600,5700 we may dump some 1080ti

I personally don't see the 3090 doing 150 mhs and feel the roi is going to be significantly longer than the 3080's 10-12 months. If the 3090 ends on the lower end of eth performance your looking at potentially 2 plus years before it's paid off. For me I can't justify the difference in time to roi.
Well we are still guessing a bit on prices and hash rates. I put my name on this list for all models the 3070 the 3080, 3090. https://www.nvidia.com/en-us/geforce/graphics-cards/30-series/rtx-3090/So is the consensus here the estimated power savings from the 3000 series for the purposes of mining justifies dumping 1000 and 2000 series cards from Nvidia? Do we yet have some definitive or reasonable numbers that show effective power usages? I've seen estimates but nothing more than that at this stage. If I had a ton of 1080ti's and no better gear I would put some up for sale. I would put some of the sales on the side for the 3080 or 3090 I would buy this card now. https://www.newegg.com/msi-radeon-rx-5600-xt-rx-5600-xt-gaming-mx/p/N82E16814137571?I tried more then 9 amd models I like this one the most. I would try to become. ⅓ 1080ti ⅓ amd 5600 ⅓ nvidia 3080/3090 once I reached that goal I would sell the remaining 1080ti's and look at the big navi card or the 3080/3090 to put the rest of the 1080ti sales money into. For me and my team we are 12/13 1080ti 1 1080 1 1070 4 1660 1 1050ti and 25 new amd 5500,5600,5700 we may dump some 1080ti I'm considering finally making the switch to SMOS and currently considering options. I've got a mix of older RX480/580 cards that I plan to sell and it seems like that 5600XT a good replacement plus a sizeable mix of 1070/1070TI/1080s all of which have long been paid for/off in 6/7GPU configurations. Do you believe the power savings alone is going to be enough to justify going in the red short term to make the switch? It seems like it clearly would be in the case of the AMD cards.

miner software optimization might get 3090 to 150mhs...hopefully ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) No, Eth is memory bound, 3080 and 3090 have the same memory type and speed so the minor difference we will see would be due to 320 vs 384bit bus width. And this isnt on-die HBM, dont expect 90+ on anything. I'm not sware of any new instructions except FP64 which is of no use in mining so I'm not expecting any signficant coding improvements, even for compute bound algos. The new compiler and runtime might provide some minor improvements but unlikely to be significant. The default intensity will need to be updated for the new cards but it can always be set manually.
