From my first tests with cuda 8 rc, sm61 doesnt improve anything... over 5.2, maybe this rc is not yet optimized for the GTX, but only for the Tesla 6.0

To resume, the 10xx are more like overclocked maxwells with a lower power usage :p Remains the 1080 special memory which seems a crap for now on mem algos
They are tweaked maxwells with lower power usage, according to some in-depth analysis from ixbt
It seems Nvidia focused on game/VR improvements
1 thing that should be faster - context switching/ switching between compute/graphics or different

Yup, but seemingly NeoScrypt is performing like shit on the 1070, regardless of it having faster GDDR5 then the 9xx series. Ethminer wont even run on the 1070 in w8.1

Both the 970 and the 1070 have a 256bit bus.

neoscrypt is performing very well on a 1070, around 1150 on LINUX, with the correct oc, this is 70% more than a 970

1150 ? not more
my 970 gives 710kh/s peaked with Neoscrypt

Well that's exactly what we needed: maxwell with lower power usage.

Yes and No Pallas. It would have been great if we had faster & low latency memory access (there's no significant improvement there over maxwell, if at all). Still, for compute-heavy stuff, great improvement.

So only in Nix? Then it's still broken.


Yeah, the 256bit bus on the current generation of GPUs is rather disappointing. That seems to be a largely contributing factor to current poor performance in memory hard algos.

A lower price to performance ratio would also have been nice. The lower power usage is the only advantage over Maxwell ATM.

you think a 70% increase is low? are you joking, also it appear that it can be overcloked even more, this was done with only +200 on the core(1750), these card can reach crazy value when overcloked, like 1800-1900

to me it's more than enough, in the end it's the 2x perf/watt that everyone was expecting since the beginning....

A lower price to performance ratio would also have been nice. The lower power usage is the only advantage over Maxwell ATM.

uh what? it's freacking 70% faster on both etheruem and neoscrypt, how this is only "power advantage"

Most algos are around 50% higher than their Maxwell predecessor and so is the price. When Maxwell came out it
had an immediate price advantage in addition to the power saving over Kepler.

there is also a power advantage besides the 70% more hash, because a 970 at 700khs mining neoscrypt, will consume like 170w against 145w of a 1070 with 1150khs

what i meant is about the compiled cuda arch, is sm61 was not faster than sm52 on these cards... at least for now. So "older" ccminer versions should be enough for them.

The main hardware improvements made for Tesla are not present in the GTX (or very limited/emulated) and are not related to mining (FP16x2 instructions)

I replaced just my 970 with a 1080 and the temp in my room has been night and day difference.

The only thing I hate is the price but oh well.

As Epsylon3 said above maybe down the road the cards can be taking advantage of for mining.

If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks Wink

The price/performance may not be ideal yet but there should be much more potential for SW optimizations.
And the power savings alone is worth it unless Maxwell prices drop significantly.

I also wonder about the possible 32 GB barrier. I'm not aware of anyone getting more than 5 980ti's working.
With the 8 GB on the 1080 & 1070 this could be limited to 4. Hopefully this is just a simple driver fix and not something
more fundamental.

there is already one guy on the ethereum forum running 3 x rig with six 1070 each, without problem, so apparently this is not a real issue, or maybe only with windows? he is using linux

Thanks, that's good to know. Either it's fixed or the 980ti problem was a different issue.

BTW this is what it looks like mining NeoS on a 1070 in W8.1 x64. Newest Nvidia drivers.



The MCU isn't being maxed out, which is usually what happens if something is memory bound (MCU usage is actually less vs 970). There is some weird sort of tuning issue with NeoS that needs to be ironed out, pretty certain once it is performance is up to par.

You also have a integrated NeoS miner, thought it was worth mentioning where discussions are currently happening.
