1660 Super Poor Performance
I have a 1660 super with the Razer Core X plugged into my 15 inch 2017 mbp with a 2m cable. Although I don't have an external monitor and I'm using my mac's internal monitor, I feel like the performance is worse than it should be. I'm getting 50% less performance or more compared to the 1660S' full performance and I didn't think that the difference would be that big. Ex. when I play COD warzone I get only around 45 fps on the lowest settings on 1080p (mostly when landing and on-ground because places like the dropship or the gulag work fine); compared to the 1660s on desktop, which gets an average of 130 fps. To make sure, I checked the host to device speed and it seemed fine at around 2200 MiB/s. Is the 1660 Super just a bad card for GPU enclosures, or is it because I don't have an external monitor? I was expecting a 20-30% performance drop but never thought it would be this bad.
Start by running software that isn’t known to be completely broken (COD Warzone).
Check your score in 3DMark’s Time Spy benchmark and you’ll see that your card is fine.
(Assuming you have Windows 10 Power and Processor Management and Nvidia Control Panel’s Power Management Mode set to Best Performance)
@mini-i5, I tested using the Heaven Benchmark and I got around a score of 1500 average. This is 800-900 lower than the scores from: https://www.vortez.net/articles_pages/zotac_gtx_1660_super_twin_fan_review,8.html
Considering the bottleneck of the thunderbolt 3 + internal display, is this the performance that I should expect?
If you own the Zotak 1660 Super model you are referencing, this 2017 MacBook Air eGPU build scored the same (2348) in Heaven with a 1080p display attached.
And that’s with a dual-core, TB2 MacBook Air.
@mini-i5, I'm guessing it's probably because I don't have an external monitor that's bottlenecking. I've tried the standard TB3 cable provided by Razer but the results are still the same. Btw I have the twin fan Gigabyte version of the GTX 1660 Super. I was wondering if I disabled my DGPU (Radeon Pro 560) would I get more bandwidth to my internal monitor?
@mini-i5, I've tried running other games such as apex legends, valorant, csgo, etc. and they perform terribly compared to what I thought. My benchmark score on Heaven Benchmark is about the same as a desktop GTX 970 but why is my GTX 1660 super egpu performing worse than the GTX 970 in most games?
@mini-i5, I have Windows performance set to best performance, although I there are no options in Nvidia Control Panel since I do not have it plugged it into an external monitor. I am running 2880x1800 on the desktop which my Radeon Pro 560 controls and in-game I mostly run 1920x1200 or 1680x1050. Although Nvidia is not set to best performance, my GTX 1660 Super is always running at 100% when gaming.
