Hello,
 
I just purchased and installed a new EVGA GeForce GTX 1660 SC Ultra Gaming video card, P/N: 06G-P4-1067-KR, in my Dell Precision T5600 workstation.  According to Passmark's GPU Benchmark website, this video card should benchmark at ~11,000.  I'm only getting ~7,000.  I have the card installed in an PCIe 3.0 16x slot and have connected the 8-pin power cable.  I've re-installed the OS, Windows 10 Pro, twice and used the current Nvidia driver.  What am I missing?  Is there any way to troubleshoot the performance issue?
 
Thanks in advance,
 
Rob
 
P.S. - I just built this system based on this article: MAKE MY PRECISION T5600 IN TO A GAMING COMPUTER

While running the benchmark leave msi afterburner running in the background. After the benchmark completes look at the msi afterburner hardware monitor graph, and see if the card was running at least 1830 MHz on the core clock, and 4000 MHz on the memory clock through the graphics tests.

Try a graphics card benchmark like Unigine Superposition and see what you get.

I agree, the CPU May be the issue. If the CPU is too old and too slow, it will not produce work fast enough for the GPU.

Which CPU does your workstation have?

Hello,
 
My Dell Precision T5600 has two Xeon E5-2665 CPUs.  The Passmark score I'm getting for the CPU test is 14,000+.
 
I just completed the MSI Afterburner Overclocking Scanner test and it shows my GPU clock running at 1920Mhz and a memory clock running at 4001Mhz.  I also performed the EVGA Precision X1 VF Curve Tuner Test which showed the same 1920Mhz CPU and 4001Mhz memory values.
 
I reran the Passmark 3D Mark test with the Afterburner application running in the background.  The application did display the same 1920/4001 values during the test.
 
I reran the Passmark 3D Mark test again, this time with the Task Manager running so I could watch the CPU utilization values.  The CPU is barely used, less than 10% at any time during the test.
 
Is there anything else I should be looking at?
 
Thanks!
 
Rob

Hello,
 
Looking around online, I found a suggestion to verify I'm running PCIe 3.0.  I've attached my GPU-Z info.  I also modified my BIOS "PCI buses" value from 64 to 256.  After making this change, the system is still benchmarking at ~7,000 (4,000 below what's expected).
 
Again, thanks in advance for any more troubleshooting suggestions.
 
Cordially,
 
Rob

Hello,
 
I ran the Unigine Superposition benchmark as suggested above.  That benchmark delivered a score of 10151.  I'm not familiar with this benchmark tool so I can't say whether this is a good score or not for my video card.  Using the "Compare results online" link, there's no exact match for my card.  The closest card I found is an "EVGA GeForce GTX 1660 SUPER 6GB" which scored between 7917 and 12037.  There are only four samples for this card so I can't say how reliable the scores are.
 
Again, thanks in advance for any troubleshooting ideas.
 
Cordially,
 
Rob

Did you have the vertical sync option inside the nvidia control panel set to off, or use the 3d application setting when running the passmark graphics tests? If no, that could be the problem.

The system has been and is currently configured for "Use the 3D application setting".

Hello Sajin,
 
That is a very cool suggestion.  I'm still not seeing the benchmark value I think I should be seeing but my overall values have all gone up.  Anything else I could try?
 
My "Balanced" power benchmark value was 7,015.8
My "High Performance" power benchmark value is: 8,630

The Xeon CPus in your system are quite frankly ancient. They are Sandy Bridge 32nm dies which debuted in 2011 and the server variants in 2012. Couple that with the fact that they are at 2.4Ghz and the fact that multi CPU systems historically do not perform in games or game benchmarks very well and I'd say you have the perfect storm of an underperforming system.

Hello,
 
I've seen two comments so far on the performance of my CPU.  I've run Task Manager while running the performance benchmark programs.  I've never seen my CPU utilization go over maybe 5%.  Wouldn't a slow/inadequate CPU be at 100% if it couldn't keep up with the video card?
 
Thanks in advance,

Try setting your power management mode inside the nvidia control panel to adaptive.

That means precisely nothing. Just because task manager doesn't show your CPU being at 100% does not mean that your system isn't heavily bottlenecked. Which it is, your CPUs instructions per clock cycle are far and away below what a modern CPU can handle. What task manager is showing you is only how many cores are doing something that is all. Games and game benchmarks are not going to fully populate 16 cores with tasks. They are going to be run on 2-6 cores at most that will be doing the heavy lifting. Your CPU instructions per clock are your real enemy here and compounded by them at a very low clock speed you are not going to see very good gains in gaming related tasks. Even if they did populate all 16 cores available on your system, their low clock speed and low instructions executed per clock cycle in comparison to what modern CPUs can handle will still leave it far behind. 
 
Sorry this isn't what you want to hear but it's what's happening in your system. The benchmark you posted from Superposition is in fact in line with what you should be expecting with your parts.

Do you not realize that his 2.4Ghz CPUs from the year 2011 are what's causing his lower than expected results? He's using Sandy Bridge 32nm cores at 2.4Ghz if you haven't picked up on it yet. 


 
All the trouble shooting in the world isn't going to make them perform on par with what today's CPUs can do. Not saying you shouldn't try to help but there is only so much that can be done with what he has.

I am aware of that. I was just trying different things before suggesting a newer cpu.

Hello,
 
I appreciate your willingness to help and candor about my rig.  I just purchased the Precision T5600 ($300), along with some parts ($45 32GB RAM, $90 500gb SSD), to build an inexpensive virtualization lab for my RHCE exam.  I figured I'd throw a decent video card in it for some light gaming (Kingmaker, The Division, Deus Ex, etc.).  What's the best way forward?  Would replacing my existing E5-2665 CPUs with E5-2680 CPUs help?  Should I see about returning the GeForce 1660 card and get a less powerful card?  What video card would you recommend that wouldn't go to waste in this system?
 
The inspiration for the gaming part of the build is based on this website: MAKE MY PRECISION T5600 IN TO A GAMING COMPUTER
 
https://www.greenpcgamers.com/technology/make-my-precision-t5600-in-to-a-gaming-computer/

 
Is that website a total fraud?
 
Thanks again for all your help and feedback,

Instead of focusing on your benchmark score I would try playing some games on the system first. See if the performance is acceptable to you or not.

For gaming a T3600 with a single E5-1660V2 would be better than your current setup for gaming.

For a cheap budget gaming build you would have been better off with a Ryzen 5 1600AF and a B450 board. But since you already have what you have it's too late for that. No, getting a very slightly faster CPU from the same era wouldn't do much of anything except waste money. The architecture of them is the same, adding a few hundred Mhz to the core isn't going alleviate the bottleneck present. Having said that it's not a total wash, just try playing some games instead of worry about scores in a benchmark. Your system should still be able to game decently. And while I wouldn't go as far as to call that site a "fraud" it is DEFINITELY more than a little misleading. Trying to pass off decade old CPUs as "high end" is deplorable. For the same money you spent you could have got a much better and more modern system.

Sajin & CraptacularOne,
 
I took your feedback to heart and built a new system using a MSI MPG X570 Gaming Plus motherboard, AMD Ryzen 5 3600 CPU, 32GB of Corsair XPX 3200Mhz RAM, and the GeForce GTX 1660 card from the Dell Precision T5600.  Using the new board, chip, and RAM, I'm getting a Passmark v10 bechmark score of 14,739.  The performance difference is profound and I wouldn't be enjoying it without your help.  Thank you both for your candor, patience, and advice.
