Thoughts on 2 Laptop video cards...
We're looking at getting Lenovo Legion for our travelling streaming setup. Using Thunderbolt port for Blackmagic recorder.
Model name: Legion Y740
CPU: 9th Gen Intel Core I7-9750H @ 2.60 GHz Six-Core
Storage: 1TB SSD
Graphics: Nvidia RTX 2060 6GB OR GTX 1660Ti
First question, anyone have any thoughts on this as a system?
Second questions, should we go for the RTX 2060 or GTX 1660Ti (which is about 300$ cheaper). Seems like the GTX 1660Ti shows only about 10-15% less performance, not sure its really worth the extra cost. Will either be able to make use of GPU for compression?
Thanks for the inputs.
I'm not an apple fan I have to admit. My windows system is relaxed with either of them. But I haven't compared or meassured. And the fact that I didn't looked at it is maybe an indication that there isn't much difference. If, I would have noticed. Running on a laptop you need to look closer because resources are so more limited.
Well, Xeon with many cores, 40 PCI Lanes, Nvidia 1060 or 1080, PCIe NVMe storage and you are set for the desktop.
For a Laptop I would look for names like mobile workstation. I just googled and found https://store.hp.com/GermanyStore/Merch/Product.aspx?id=2ZC64EA&opt=ABD&sel=NTB
Some i7's will have 40 lanes as well. You can check at ark.intel.com and compare. So generally Good CPU, dedicated Nvidia GPU and fast Storage.
Capturing over NDI solves the problem of what capture solution to pick for mobile workstations.
Jens Jarke can you give thoughts on this workstation
the processor supports up to 48 lanes. The processor seems little slow. Has lots of expansion. Is it overkill ok ok?
That machine is massive. More targeted as a server. But who cares. Two CPUs of that size will do the job in combination with that GPU.
Better to have a relaxt system.
PS: You may want to use the HDD as system drive and SSD as storage (maybe upgrade size). When you record a bunch of cams/streams you don't want to fall short on the drive speed.
Jens Jarke this looks like Dell’s solution. https://www.dell.com/en-us/work/shop/workstations-isv-certified/precision-5820-tower-workstation/spd/precision-5820-workstation/xctopt5820us_2
any thoughts between the two?
From experiences I would recommend to have plenty of headroom in terms of CPU and GPU. Versions increase and requirements rise. Today it's one stream, tomorrow a second and addition ingests, records, outputs, NDI, whatever.
The more headroom the more stable the system. If wirecast is using 80%+ you will run into unexpected issues.
My opinion is NOT to go for BMD. Take a look here at the forum what the cards cause for issues and compare to magewell, which I would prefer. The magewell you buy, install and will never cause problems. With the BMD you will have constant updates that come with trouble. If you need to go for the budget go for BMD. Best bang for the bug. If you want to have a nice unproblematic experience go for magewell.
Jens Jarke Thanks. doesnt look like Magewell has any cards that output SDI. So we may not have a choice for that but BM. On a related note. In terms of PCI bandwidth, how many lanes does one stream take up? Assuming our requirement is 2 input, 1 output, Nvidia card output to 2 monitors. How much use is that appx? Is there some guidelines around it?
So, looks like we found a laptop & Desktop system for our streaming. Our options are pretty slim here in India, but Dell & Lenovo have ones we'll go for. Let us know your thoughts...

For input card, again our options are limited as we need 16 channels of input/output so for now BlackMagic has the only one. We saw some comments in Reddit forum that say BM isnt as stable as they some would like, but we're hoping its ok for our more limited needs
