It will be interesting to see if the increase in performance in games is also seen with Vegas with the 5000 series. From what I've seen here when used with GPU the vast majority of the power of 3900/3950 is never able to be utilised

Consistent with what @VEGASPascal pointed out, I have observed a big performance boost on my machines that have an Intel igpu assigned to decoding while a pcie gpu does the rest. That might put amd cpu's at a disadvantage since it's unlikely their motherboard chipsets would ever support an Intel igpu. Unless there's another way to get Vegas to do similar load splitting. A few users here have reported successfully getting Vegas to recognize installing both Nvidia and AMD video cards in the same machine. Which suggests that a couple of lower power-draw boards, like a 1660ti and a 5700xt, might just keep up with a big power hungry triple-width 3080 or 3090. Or a passively cooled Intel igpu on a motherboard. Just a thought.

@TheRhino .. Thanks .. I'm aware of the 5950x coming out Nov 5 .. 20% faster .. ok .. sounds good if I could actually get one .. same thing with the RTX3070 .. sounds great but can I get one any time soon? .. Likely I'll wait for the 5950x and see if I can get one .. unless the 3950x has a big price drop soon ..

wait for big navi amd gpu (28oct)

Yes, my 9900K workstation benefits from having BOTH an internal iGPU (QuickSync) and a VEGA 64 LQ PCIe GPU. On paper it should not match an AMD 3950X & 2080ti, but in Vegas & Photoshop, etc. it's close for a LOT less... 18 months ago I only paid $1350 to upgrade an old Xeon to a 9900K, VEGA 64 LQ, ASUS Z390 WS, H150i & 32GB... I was criticized by the AMD owners on this forum for choosing Intel, but I have to have Thunderbolt 3 on at least one workstation... However, now that the AMD 5950X is about to be released, I at least would want to see how it, the Big Navi, etc. perform with Vegas before choosing something else...

@Howard-Vigorita I know you do benchmarks all the time, can you post those results here. I'll see later if I can see a difference between intel and Nvidia decoding

I'm a bit behind benchmarking but what I've done during 2020 so far is online here. I didn't test with the igpu disabled in bios, however, so it's still in action to some extent even if not explicitly invoked in Vegas. But even so, selecting Intel as the decoding igpu in v18 consistently outperforms selecting amd. On material for which gpu decoding is possible. The big performance jump I saw, as I recall, was for h.265 when the latest v17 build came out. I reported it here. Older versions of Vegas supported Intel decoding when available but something got souped up with drivers and that build. Got 2 systems with no igpu and have my eye out for the rumored Xe. If it's too expensive or never appears, I'll probably try out a 1660ti.

I did a comparison between intel and Nvidia decoders. Nvidia decoder was faster by 10% on my computer

Here is an interesting counter-intuitive development for those contemplating a system using a Ryzen 5950X, 5900X, etc.

Executive Summary

Though two channel memory controllers in the past often performed worse with four DIMMs instead of two, the latest chipset from AMD performs measurably better.

@john_dennis I watched that with the review of the Ryzen 5000 series CPU's. My problem is I already have a 3900X with 2 DIMMS (16GB each) and have contemplated adding two more. Not sure what type of performance "hit" I might experience, but I have no plans on going 5000 since this might be the last upgrade on the X570.

Now, if they say the 5000 series CPU's will be going forward with "AM5" socket, maybe the CPU's will become a consideration....

So .. If I decide on the Ryzen 9 5950x, I'd be better off with 4 sticks of ram than with 2 sticks? .. Correct? This would mean if I want 64gb ram total, 4 sticks of 16gb would run faster than 2 stick of 32gb ?? ..

That appears to be the conclusion of that tester.

@Reyfox

If I had a 3900X with two DIMMs I wouldn't even be reading this thread.

Well, you really need to watch the video, all the way through, and especially "listen" to what Steve Burke is reporting. It is not only the "4x8GB" sticks over "2x8GB", but he also has specifically gone through and set the various timings, for the modules themselves. Of which, with other YouTubers like Hardware Unboxed, JayzTwoCents, etc., on the AMD Ryzen Memory settings, they use a couple of software apps to help not only get the timings for each module for the particular manufacturer, but also on which timings to actually set in your computer UEFI/BIOS.

So, if you are not planning to go into that much depth, this now becomes one of those "Red Herrings" in the computer world. Though, as always, "Your Mileage May Vary".

My recommendation? Stick with what you have already done on all the leg-work, especially the checking of actual memory compatibility to the motherboard/processor, put the new "Beasty" together, taking your time of course, and enjoy the Build!

Again, how many extra "FPS" will you actually see playing games with this "Memory Tuning"? Oh wait, you are building a VIDEO EDITING Machine! (Sarcasm :) )

My main two thoughts: 1. BACK-UP! 2. Invest in a UPS And just for Re-Assurance: BACK-UP those files!!!!

@Chief24

The way I build systems:

• Read all the hoopla in the 90 days before a new build.
• Select a platform with good promise made by competent manufacturers.
• Assemble all the parts.
• Install the O/S
• Backup System Image
• Install applications
• Backup System Image
• Tinker with clocks, timings, fan curves, etc. ad nausea.
• Set everything in the BIOS at default.
• Restore the system image.
• Forget the whole thing for three years and 9 months.
