i have a homebuilt rig with Intel(R) Core(TM) i5-8600K CPU @ 3.60GHz [Family 6 Model 158 Stepping 10]
(6 processors) with 16GB DDR4 RAM and a NVIDIA GeForce GTX 680 (2048MB) driver: 451.67 OpenCL: 1.2
Would adding more RAM boost production or would i be better
off upgrading my video card to a GTX 1660 Super ?
Any idea how much improvement i would see from those options ?
Mike
Greetings TouchuvGrey
The CPU and RAM are definitely fine for crunching.
But yes your next step would be to upgrade the GPU.
A GTX 1660 Super or even a 1660 ti would be a good step
These cards runs cool and more energy efficient than the GTX 680, even quieter.
Just some food for thought, am sure other member will throw their 2 cents in as well.
I have a GTX 1660 Super and our team Captain (Dingo) has the 1660ti model.
Cheers

Totally agree with
tazzduke.
I agree too. I got a GTX 1650 for the low profile card and efficient but lacks the cuda cores. 1660 super and ti is a sweet spot. Find one at the right price and be a decent low power rig to crunch away on.
If your feeling lucky you could play the EVGA GeForce RTX 2060 KO lottery, I was tempted when i saw the cards cheap. The KO range is ment to be rebinned 2070 Super and 2080 GPUS and sometimes perform alot better. https://youtu.be/mUFRBnJdx3Y -Gamer nexus review
I'm just not lucky or a gambler so didn't like my odds and there is pros and cons to getting the defective crippled 2080 chip
I have no idea how the 1650's, 1660's, etc perform with Milkyway@Home. Radeon cards are king of Milkyway.
RX480's, RX580's, Radeon VII, or old R9 280X (but they are heavy on electricity)
The 16xx cards are very efficient and great for other projects than M@H like Primegrid.
Oh..this list will help.

Thank you everyone. Chooka, i had not even considered
a Radeon card as i have been using NVIDIA cards since i
started modifying and building computers 15 years ago.
:banghead

Chooka is dead right. Milkway uses double precision which is 1/32 speed on modern NVIDIA and 1/16 of single float on modern Radeon. Depends on what projects your running. A second hand Rx 480-rx580 would run amazing still for milkway. A Radeon VII is the dream card but never seen them for sale.
My Radeon cards are great from Einstein and Milkyway but I get flogged at Numberfields, Primegrid. A guess a mix of cards is good sometimes but I like space projects the most. I have thought about building a PC specifically for Primegrid. Intel CPU and I'd probably get a 1660 SUPER or a Ti...something like that because they sip on the power. A 2070 SUPER would be ideal price vs performance for me but the power usage goes up quite a bit compared to the 16xx cards.
The other option is the 5700XT I suppose. They are nearly as good as a Radeon VII at Einstein.... and yes Radeon VII's rarely appear for sale and when they do a second hand one sells for about the same price as they were new $900.00.
Traditionally, NVIDIA cards use less power than the Radeon cards if that's a factor. The 5700 may be an exception.
i came over here from SETI@Home after crunching for them
for 16 years, so i am a space nut too. RX 580 is less expensive
that a GTX 1660ti so i like that. Hmmmm, will have to think on this.

I've found these 2 webpages useful for comparing GPUs ...
https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units (https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units)
https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units (https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units)
Lots of good information.
That is good. If i'm reading this correctly the Radeon RX580 is about twice
as fasr as the GTX 1660ti on double precision ?
you can do direct comparisons om many different cards here
https://www.videocardbenchmark.net/
Mike
Yeah AMD should be at least twice as fast as same tier Nvidia. I can run tasks on a 1660ti to compare. I will say the rx570/580 AMD Polaris GPUs run more optimal at Milkyway if that project is your focus. I have a 5600xt which if fine at Einsteins single precision but not optimal at Milkway. Not sure if its drivers or the way the Navi processes double precision or memory, not sure. It's not terrible but should be theoretically nearly x4 faster than my rx560 polaris card but only just over twice as fast. It should dominate a rx590 on paper but its maybe the same speed or even slower than the rx570 or rx580.
Milkyway@home Separation times - running single WU per GPU *credit much the same 227-240 points each
RX560 'polaris' -208 seconds Benchmarked 164.7 GFLOP Double
5600xt 'Navi' - 135 seconds Benchmarked 508.7 GFLOP Double
GTX 1660ti @80w TDP - 233 seconds Benchmarked 178.6 GFLOP Double
Vega 7 integrated GPU - 361 seconds (just because) Benchmarked 89.24 GFLOP Double
Times show raw power is not the best indicator of speed across cards and application
*** I found these card times off another site** https://forums.anandtech.com/threads/milkyway-h-benchmark-thread-winter-2016-on-updated-1-2019-gpu-cpu-times-wanted-for-new-wus.2495905/
RX 580, GPU 1350 MHz 97.3s
RX 570, GPU stock 121s
RX 480, GPU ?? 110s
When i get my RX580, can i put it in the box along side of the GTX680 i have now ?
i've run dual ( Nvidia ) card setups before but i've never
tried mixing cards.
Ooh I'm pretty sure that can be done but I've never tired it so don't have the answer sorry.
I run AMD and NVIDIA cards side by side in all my machines. Never had issues. Sometimes the raw power of the AMD is good sometimes I need something CUDA compatibility. Works well it the Power supply can feed both.
I agree. You can run mixed GPU's without having to code for it.
OK, Radeon RX580 finally installed and running. Not sure why but it took
about 8 attempts to get the card in and recognized. Of course now it doesn't see the
NVidia card right next to it. i'll worry about that tomorrow.
Mike
When i open the Radeon Software i see that i can change a lot
of the settings. Any suggestions as to what should be changed ?
The one i did notice and TRY to change is where it says Under Graphics, Advanced
GPU Workload. i have used the dropdown to change it from "Graphics" to "Compute"
Clicked "OK" to restart RSX, but after doing that it is still set to "Graphics". Any suggestions ?
