Mining performance of Nvidia RTX 2080 Series

[cudapop]

Utility of the new features depends on the algorithm, for example:

Tensority algorithm - Uses quad 64-iteration 256x256 matrix multiplications, input matrices are composed of 8-bit quantities, results are compressed from 16-bit back to 8-bits prior to the next matrix multiply operation. This allows use of:

1) DP4A 8-bit vector instructions (present in Pascal GP102/104/106, present in Volta V100, unknown currently for Turing - still waiting for CUDA 10 SDK to be available to verify this feature).

2) Tensor core FP16 multiply with FP32 accumulate. FP16 allows for 8-bit integer input values to be stored with no loss in precision, FP32 accumulate allows for 16-bit integer result from 8-bit multiply to be stored with no loss in precision.

3) Tensor core INT8 mode (new in Turing, absent from Volta). If accumulate is in INT16 (likely as this is a matrix multiply operation with 8-bit inputs, should be verifiable once CUDA 10 SDK is available) this would then allow for use of this mode in this algorithm. Throughput would be twice that of FP16 multiply with FP32 accumulate from #2.

4) Parallel-issue FP32+INT32 CUDA cores (introduced with Volta, also in Turing). Similar to #2, FP32 execution path in cores will allow for 8-bit integer multiply and 16-bit integer accumulate.

Groestl algorithm - (Note: I have not coded a CUDA kernel for this, so I am just speculating based on the specs for this algorithm). Uses matrix multiplication in it's "MixBytes" transformation step, input matrices are 8-bit values, hence the same 4 CUDA features discussed above are possibly applicable to this algorithm as well).

there could be a surprises with RTX series if mining software devs find a way to utilize the tensor cores, if not the performance bump wont be that impressive considering the price point.   

As the tensor cores are FLOATING POINT, while mining is an INTEGER function, as I mentioned back when the new Tesla was introduced I don't see them being a factor AT ALL for miners.

You are staying ETHash algorithm is an integer only function? Are you sure about this?

Some of the divisions in here looks like it utilizes floating point calculations.

[cudapop]

Ethash is all integer (and logical operations), the division operations as well. You can verify this by pulling the source code of Ethminer from Github and checking the kernel files (.CU and .CUH files).

In my own Ethash kernel, it's all integer/logical operations as well.

The redeeming thing about getting RTX 2070 or RTX 2080 is that in 6 months time after you're done mining, you still have the fastest GPU on the market. This makes it easier to resell back to the gamers.

in 6 months time you will not even get 10% of the money you spent on it and will be in sorrow why you used it for mining instead of using it for gaming. It will be a disaster to your brain and especially after amd launches their 7nm hehe

If you buy for gaming then great, if not gaming then mine using it but you need to prioritize gaming over mining and you will be happy with yourself, trust me, this is btc's creator idea,

Imagine if Bitmain gets a hold of these GDDR6 memory chips and uses them in their private ASICs.

I imagine one ASIC would be able to easily achieve 1GHS of Dagger Hashimoto speeds.

Either way, the ETH dev really needs to do something to keep the ASIC resistance, many miners even agree with taking a issuance reduction just to keep ASICs off the network.

Problem is that Vitalik doesn't give a damn about miners. Look at what he says during some of those Ethereum core dev meetings (vids are on YouTube). He thinks ASIC is not a problem up until this day.

And then you look at the relative price of ETH vs BTC. Explains a lot, doesn't it?

It’s look very interesting 

[discoverblockchain]

So the overall sentiment is that the price is not worth it?

How do you figure? All AMD needs to do is release a new series of GPUs that would make the RTX 20 series obsolete as well..

My opinion is that it is too late to get into mining at this point in time, whether or not you have free electricity or not. There are simply too many threats just around the corner that could leave you high and dry with computer hardware.

Based on what we can compare, no its not. 
If you want to get into mining, you are better off buying 1080 Tis off ebay.
Though as of recently I am seeing those sell for over $550 each.  Prices are likely to keep climbing until its in cost proportion to the hash rate of the 2080 Ti.

[telemen]

with such a price these video cards are absolutely not interesting for mining, especially against the backdrop of a strong fall in the whole crypto currency market. better to take cards of the past pokrleniya!

The same can be said about Q1 2017. Crypto prices were not attractive back then. Those who started mining at beginning of 2017 are probably millionaires by now.

I purchased 1 EVGA RTX 2080

Cost was 750


It is worth having one of them.

I don’t see that a 1200usd 2080ti is going to be much better then the 2080

The 2080ti has 11gb RAM at a faster mem speed. It'll be a similar difference as between the 1080 and 1080ti.

750 seems good deal. where?

It would be cheaper to buy multiple 1080Ti than the 2080ti.

[tenebriscaelum]

Given that this model (RTX 2080Ti FE) costs $1,225.00 , the increase in hashing rate from 55 to 69 MH/s is not enough to justify the price. The other question important for mining application is how much one can overclock this card.

That is true and it is just like milking the consumers and it is not lime gddr6 is hard to produce like hbm2, also if nvidia say that the tech it brings justify the price it can only br used by gamer also the ray tracing is not yet evident in many games. As such it will still be a good buy for the 1080ti for mining specially if price cuts has been made because of the launch of the 2080ti.

I agree  but 1200/750 vs 700/500

means  the 2080ti cost 60%  more then the 2080

and the 1080ti cost 40% more then the 1080

so the 2080 is better then the 1080
