Thanks Azmodes. It's clear then, no significant perf increase for PG compared to a normal gtx 2060.

It arrived today and while I wasn't yet able to check the chip, the speed on manual sieving (~500 P/day at GFN21, B13) suggests no 2080 levels of performance.


What does the GPU-Z show? I mean what's the gpu it shows? Is it the TU104 ?

So, i stumbled on this: https://www.youtube.com/watch?v=mUFRBnJdx3Y
They are saying that EVGA RTX 2060 KO has a die TU-104-150, and its non gaming perf is MUCH faster than a normal 2060 rtx is capable of.

I got no free money right now so i cant order one, if anyone has allready that gpu i'd like to know what is it able to achieve in PG?
It should be an exxellent bang for buck card.

Quote: The RTX 2060 KO performs 26% to 47% better than a normal 2060 in some applications.
It's not just that TU-104-150 is now in the RTX 2060 KO, but that NVIDIA might have forgotten to disable some of its performance in the new RTX 2060 SKU. The TU-104 GPU came from an RTX 2080 -- or RTX 2070 Super -- and it's supposed to be a salvage chip with disabled features

Is it something like this, you're suggesting?

I want to see teraflops per second
EDIT: In the strange world we live in, that information disclosure may be discouraged?


Petaflops per hour would be better and maybe? easier to implement.
Considering that most single gpu-s are in the teraflops range.
Looking at FP32 (float) performance only, then i have been running at 10 teraflops for years now.

I am using 436.15 from nvidias site and it seems to generate no errors.

So, a month has passed, and i have had no problems with my 1660ti or driver stability issues. Recently nvidia released a gaming driver 436.15 and i decided to try that and it enabled all of the compute capabilitys, so its even better now, thanks nvidia.

Using it on my good old PII hexa on asus sabertooth with 16gb ddr3 and 256gb SSD runnin on win7 pro 64. Runtimes compared to my old gtx 1060 3gb:

Primegrid AP 27:
gtx 1060 3gb 1 wu at a time: runtime per wu ~2180 sec
gtx 1660ti 6gb 1 wu at a time: runtime per wu ~1190 sec
gtx 1660ti 6gb 2 wu-s at a time: runtime per wu ~2400 sec

Primegrid pps sieve:
gtx 1060 3gb 2 wu-s at a time: ~540000 points per day
gtx 1660ti 6gb 2 wu-s at a time: ~1,40000 points per day (410sec per wu)
gtx 1660ti 6gb 3 wu-s at a time: no difference in points per day. (cpu load is higher)
gtx 1660ti 6gb 1 wu at a time: ~ 350sec per wu or 800 000+ points per day

collatz:
gtx 1060 3gb 2wu-s at a time: 1700+ sec runtime per wu. (around 3 200 000 points per day).
gtx 1660ti 2 wu-s at a time: 700+ sec runtime per wu. (around 7 450 000 points per day).
Gtx 1060 and 1660ti are both installed on a chinese pci extender cable of ~35cm in lenght.

Asus OC 1060 3gb boost holds at 1910mhz:

Zotac AMP OC 1660ti 6gb boost holds at 1965 mhz:
https://www.upload.ee/image/10497789/gtx1660ti_.png

Asus OC 1060 3gb rated tdp is 120w, Zotac AMP OC 1660ti 6gb rated tdp is 130w (120w tdp is for non oc models, oc models are rated 130w tdp).
Measured the power draw difference for my pc with a kill a watt. My psu is corsair AX860 platinum, cause i got 3 gpus.
The cards were not installed in the pc simultaneously, and difference was around 15watts from the socket. The 1660ti pulls around 15watts more from the socket, as it should.
I used collatz for testing, cause it loads the gpu heavily.

While the 1660ti is not exactly cheap, since it is very power efficient and very fast, its a must have, and i am not dissappointed at all with its performance. Infact, it performs better than i expected.

pps sieve config that i am using for the gtx 1060 and 1660ti:
<app_config>
<app>
<name>pps_sr2sieve</name>
<max_concurrent>16</max_concurrent>

Looking at this thread, i have desided to get me a 1660ti and see what i can do with it.


Good things of course!!


Got my Zotac AMP 1660 ti today, and uninstalled mu old driver for my good old asus gtx 1060 3gb and replaced the card and installed the latest driver from nvidias website and all was fine, games and all. But opencl for the card is not there! Ok, my amd cards in the same pc were working and opencl was present, hmm? OK then...

Went through some forums and found that nvidia disables opencl for different reasons for different people. So then i unistalled the nvidia driver and what do you know my amd cards lost they'r opencl capability, niice nvidia... ok then. Downloaded the oldest nvidia driver available for the card and after installing it all gpus are now blessed with opencl capability. Reminds me of the old days with nvidia physixs, when amd card was present, nvidia physixs is disabled on ANY nvidia card.
Same old, same old. Ok, i'm going to bed now, tired and angry.

6c\6t on my netbox (+3 gpus).
8c\8t on my old gaming rig (+3 gpus).

I'm not that into cpu computing.

If you haven't been paying attention to the challenge standings, maybe you should.

All of a sudden there's a huge battle for first place in the team standings in the last day of the challenge. The Czech National Team came out of nowhere and made up a 20+ million point deficit to not only pass Aggie the Pew but is within spitting distance of the first place Sicituradastra. One hour to go...


Glad I wasn't watching, actually -- that was a real nail-biter. Sicituradastra, thankfully, managed to hold on.


Yeah, i just checked the stats and it was really close. Unbelievable.
This was a tight run, but thankfully PG server was stable like it usually is.
Big thanks to PG staff.
