so anyone have tested this gpu? what are the perf on bitcore and lux?

We should see performance tests soon. The Bitnand.com guys say they're getting the first batch for performance testing in around 3-4 weeks time.

That seems a tad late, don't these start shipping later this week?

I am seeing estimated mining performance figures of RTX 2080Ti at 69MH/s. Please see source here: https://www.bitnand.com/product-page/nvidia-geforce-rtx-2080ti-fe

Does that make sense to you? Let's compare GTX 1080Ti vs RTX 2080Ti memory performance here.

GTX 1080Ti vs RTX 2080Ti
Memory type: GDDR5X vs GDDR6
Memory speed: 11Gbps vs 14Gbps (+27%)
Size: 11GB vs 11GB (same)
Interface width: 352-bit vs 352-bit (same)
Memory bandwidth: 484GB/s vs 616GB/s (+27%)

Given ETHash is a memory intensive algorithm that does not depend much on the GPU itself, the difference in memory performance should be a good predictor of RTX 2080 series performance.

Also, just noticed a decent deal on the 10-GPU rig on the site. I'm tempted to go for it given GPU prices are also low right now.

https://www.bitnand.com/product-page/10-gpu-riserless-mining-rig

Being from somewhere near a hydro power source, my electricity cost is only 0.03c / kWh. This means I still make money monthly despite low ETH prices.

seems like a decent deal. I think what you said it great if you already have the cards, but even if you have free electricity I think the issue becomes making your investment back before a better performing card comes out at the same price. I wouldn't recommend buying anything until we see the RTX performance. Yes they are expensive now, but sooner or later they will be releasing lower end models

Hey guys , mining ETH now is like invest , mining today sell it on top or near top price.
I was mining ETH on 3 gpu only at ETH price 15usd , I was holding it and sold everything at 340 usd can you imagine the profit ??
Mine eth today and sell it at 500-600 usd , +/- within 3-4 months.

use them with the current miners or do we need new miner versions to utilize the cores?

New miners needed, as they have to utilize the CUDA WMMA (warp matrix multiply accumulate) API to execute on the tensor cores. WMMA was only made available starting with Volta. So if the current miner was not coded for Volta then it doesn't use WMMA. But If the miner was coded specifically for Volta then it may already utilize WMMA. Alternatively, if the miner code is using CuBLAS, it has to have been modified to set the mode to "tensor op math" mode for it to use Volta's tensor cores.

So in either case, if the miner was not specifically coded to the tensor core APIs for Volta then the miner needs to be modified.

Thank you for posting bro, I wasn't aware that the figures for the RTX were released. If they do meet these expectations, it's definitely going to be a really good card to mine with, although it's agreed that the price of one graphics card could be used to purchase two 1080TI's or similar cards.

The tensor cores are already usable in the "Tensority" algorithm (eg. Bytom coin) because this algo uses INT8 value matrix multiplications and the tensor cores (starting with Volta) do FP16 matrix multiplication with FP32 accumulate (ie. FP16 with FP32 accumulate can be used to represent INT8 matmul results with no loss in precision). Turing's tensor cores also support a new INT8 mode with double the throughput of the regular FP16 mode (still waiting for CUDA 10 SDK to verify if this INT8 mode uses INT16 for accumulate).

Aside from "Tensority", "Groestl" is another algo which also uses INT8 matrix multuplications.

In general, if a coin has an algo which uses 8-bit value matrix multiplications, then you can use the tensor cores for this algo.

use them with the current miners or do we need new miner versions to utilize the cores?

What doesn't kill you, makes you stronger

The big breakthrough will be the usage of the huge computing power available in Tensor cores (aka the "AI cores"). AI capabilities is something CPUs, FPGAs, ASICs and other GPUs lack... it's something that will be available to everyone for a "decent" price for the first time. If the devs manage to take advantage of those cores for mining (and supposingly share it with the community) then the RTX20 series has the potential to overcome even ASICs in some algos.
At the very least, a new algo could be created that'll be benefited by AI capabilities... then again there are plans for AI ASICs but at least in this department Bitmain won't be the sole player, Intel is close to a release too.

And who cares about Ethereum anyway? Sooner or later it'll be overcome by ARK or EOS or both. As far as I can Ethereum is already behind in usability and probably technology, at least to ARK, but I'm not an expert so take my word with a grain of salt. My conclusion comes because I'm following every ARK update, most Ethereum updates and some EOS updates.

Given current ETH price ($175), we are better off keeping the RTX 2080 for gaming Cry

The ETH price is $200 now, but it is still better not to mine with the RTX 2080.

Yes i agree. The ROI takes upto more than a year if ever the speculation is true. It is such a waste of money and time. I'd rather plant some vegetables.

Or just straight up buy ETH at the current prices. Tongue

yeah go to buy ETH is better not mine it and HODL until next year

Yeah, though TBH, people have been calling Ethereum bottom since $700, $600, $500, $400, $300, $200...

RTX series not profitable for eth. Maybe we can get new miner for RTX series.

Tensor cores are FLOATING POINT - 100% useless to mining.

GDDR6 is a given, since that's the RAM - the question is "will it out-perform GDDR5 or will it be more like GDDR 5x for mining" there.

Given the PRICING on all of the 20xx cards announced to date though, I don't see any of them being GREAT performers on a cost/benefit basis vs the 10xx series - and so far it's looking like they might not MATCH the 10xx series for cost/performance.

i think we will wait for software to make GDDR6 mining faster in some algo like today GDDR5X can mining faster than early

but im not sure it make too much different like 50%up or not
