Intel/AMD New Gen Laptop Performance on Vegas 20

Sadlylate wrote on 4/12/2023, 12:55 PM

Hi guys!

I'm looking to buy a Laptop to carry the work I've been putting out thru Vegas on my main desktop PC. This laptop will be docked for a majority of it's time at my Office space and so I'm trying to buy a higher spec laptop to sort of match the performance of my desktop at home.

I've currently have a desktop with a AMD 5950x paired with a 3080TI GPU which has served me fine throughout my edits.
My edits often make use of Sapphire and Red Giant Universe plugins & multiple video layers using AVC content (more specifically OBS recorded content)

On benchmarks the new Laptop CPU's seem to perform really well! The AMD 7945HX seem to come very close to desktop performance in multithreaded benchmarks... However Vegas is it's own unique beast to tackle and isn't always too kind to new hardware (In my experience) and so these benchmarks might not be relevant to what I'm trying to achieve.

As for Desktop benchmarks for Vegas 20, I saw that a combo of a Intel CPU + Nvidia GPU seem to have the best performance (Source)

I doubt anyone in the community would own a AMD 7945HX Laptop already but I'm very interested in seeing it's performance stacked up against the highest intel based CPU

What are you guys's experiences on laptops and Vegas? Is it even worth considering? Or still a dream too far fetched

My sights were on the Asus Strix SCAR 17 with a AMD 7945HX / 4080 Nvidia Graphics card... But it looks terrible (aesthetically) and so I'm looking for ANY excuse to buy a Intel based with a more professional non-gamer aesthetic instead/

Hope you can help me out!

Many thanks in advance!

For OBS try keyint=1 instead of 0 for smoother scrubbing, especially with cuts. That may solve the other issues you've been addressing with workarounds.

With VP 19/20, I'd disable legacy AVC and HEVC and not attempt to use MKVs.

For a system with only 32GB ram, allocating a full 50% just to dynamic ram preview is too much. Even if you're frequently making ram previews a few GB should be enough.

I'll give it a go! Generally speaking i have no issues with playback or scrubbing unless Im super deep into a project. I need legacy AVC for the OBS footage to work! I dont really use MKV's because MKVs arent really meant to be edited but did not see a performance change in leaving it on or off. For some reason the video renders a lot faster with higher ram preview % so i often up it before i push my project into render

Definitely will be getting more RAM in the near future for some more headroom!

Thank you for the snapshoots. Generally spoken, most of the settings seems to be ok for me. Typically I would set the project settings to fit the footage, what means that I would have tried to run the project wit UHD resolution. But for sure it can be done to reduce the resolution of the project to HD resolution, to improve the playback performance.

The ram allocation to the GPU seems to be high with 50%. What happens with the playback in terms of fps, if the allocation is reduced to the default figure? Are the fps reduced?

In the I/O settings, I see that no i-GPU is used? Since you have not posted the full specification of the actual PC, it is not clear if the CPU has no i-GPU, or if the i-GPU is not used by the user (if available, I would test an i-GPU to see, what happens with the playback performance).

However, I miss the important information what Vegas Pro 20 build is used, and why the latest build does not work on this machine.

For the assessment of the playback capabilities- what settings are used in the plaback settings? Best/full for example?

Since the used GPU is quite modern, it could happen that this specific footage (not optimised foe editors like Vegas) may not perform significant better on a high-end system in Vegas Pro 20.

The footage i got has both a camera and the content displayed on the screen in one file. Made to have 2 1920x1080 screens squished into one file.. It's not perfect but it works for us for now.. I have a 5950x AMD CPU and i dont think I have an I-GPU

I have 60fps solid playback on decent preview quality its more so becoming difficult after i fully completed a project with heavy FX which is completely understandable

The Vegas build im using is 214. Its a long story but I know why it isn't upgrading.

I use preview on half most of the time !

Not sure if I understand that right. Do you say that you have two screens that you display in the preview? So 3840x1080 maybe? Or do you press two HD previews in one HD preview, so that the 3840x1080 are rescaled to 1920x1080?

I mean, that is a format where I wonder what that will do with the preview really. I have am not sure about the project settings in such an case, and what the render settings should be.

Do you render to 3840x1080?

Seems to be true that this processor has no i-GPU, but the bad news are that this processor has 16 cores. Together with an RTX 3070Ti your system seems to be quite performat, ok, maybe the RAM should be increased. But that are bad news - because the question is really if the high-end laptop will perform significant better, compared with your existing system.

Build 214 is outdated a little bit - even more when the next update may come. To my opinion, it should be updated. See no reason why not.

If I understand it right, the playback seems to be fine so far. What type of FX do you use, that bring down the perfomance so significantly?

But even here the question is, if a new system will help a lot. If you are prepared to spend so much money, I wonder if it would not be better to go into a high-end desktop?

Preview on half helps for sure. But do you use best/half or preview/half? I have seen that in many cases that preview/half shows a much better performance in many cases, compared to best/half.

I think you misunderstood what im getting the laptop for, Im pretty satisfied with the performance of Vegas knowing its quirks are mostly inflicted by myself.. My desktop computer will remain where it is right now but my hope is to find a laptop that gets close to or even meet the performance of my current PC setup!

I Render out in 1920x1080 i could take a screenshot later for it to make more sense!

The effects that drain my FPS are ones from Universe like U_VHS or Ecto. I tend to use a lot of preset FX chains so i doubt it would run clean on any PC build!

Nobody here - including me - can now what your specific conditions and intentions are. I have seen that even my laptop tends to come near to the performance of my desktop what is nice performing too

AMD Threadripper 3960X - 24x3800 MHz
Board MSI TRX40 Pro Wifi with PCIe 4.0
32 GB ram, DDR4-RAM 3600
System Partition: 1000 GB SSD 870 EVO Samsung
Additional: 2TB Video 980 Pro HDD, 4 TB HDD WD Red
Grafikkarte Nivdeo RTX 3080 TI with 12 GB Ram
10 GB NAS System

So I think you will see a similar behaviour with a new high-end laptop.

The effects will always reduce the fps, but here one can reduce the preview quality.

If there are no further questions, I think we have come to an end.

Yeah i think the difference between intel and AMD are probably marginal so i think the play is just to go for whichever i can get cheaper

The newest amd cpus have an amd igpu built in which might even the playing field somewhat with Intel cpus w/igpu performance-wise. I have one system with an intel cpu plus 2 igpus built in... an amd vega8 and an intel hd630. The vega8 is a substantially better performer compared to the hd630 but they work well together with the Intel decoding. I suspect the new amd igpus are an evolution of the vega8. However I think the newer Intel igpus are still the only game in town decoding some 4:2:2 color, which allot of cameras use, and will perform better doing that if you ever need it.

Yes it seems that way! I also think both these high end chips are really good at what they do.. So i doubt its a world of difference on either side. I've made up my mind somewhat.. The Zephyrus Duo laptop that holds the AMD 7945HX is a bit too tacky for me with the two screens.. its something Ill probably end up breaking with my clumsyiness.

So it'll be an Intel i9 13980HX system with a 4080 or 4090 Laptop GPU. I'll report back when I made the decision. As i might choose the 4090 over the 4080 for the VRAM. As im intending to use a near 4K resolution screen for daily use.. I imagine ill gain a little by choosing the more expensive card

Unfortunately these laptops are extremely ugly by design unless you go for something like the Razer Blade 16. But you'll be paying a good premium so i'll settle for the gaming aesthetic.

Thanks everyone for thinking along with me & the wonderful insight.
