DPC latency better with AMD graphic cards (3 card comparison)

A worthy share. The mantra of winning PC audio systems is Intel CPU's and ATI (now AMD owned) video cards. Always seemed to have worked for me. In fact installing the budget silently cooled ATI Radeon in a PC 8 months ago stopped some rare and random crashes I was experiencing. I traced to to an iffy Win 10 video driver for the motherboard Intel on board video. So I disabled the on board video in the BIOS and put a PCI-e ATI card in.
I found this ATI card more robust than the on board Intel video chip and drivers for this particular motherboard.

You are welcome, Nvidia users may want to set the GPU to MSI(Message Signaled-Based Interrupts) mode https://forums.guru3d.com/threads/windo ... ts.378044/ELEKTROID wrote:Good info and tips, thanks Pictus.
Can use MSI utility v2(run as administrator)

Out of curiousity - what motherboard (& cpu combination) was this with ?
I'm asking as I have yet to find another benchmark/hardware test website like Anandtech where they actually test motherboards for DPC Latency... and Anandtech seems to do less and less testing these days as well... either way, the few they Z270/Z370 motherboards have tested seem to be ridiculous step backwards when it comes to DPC latency.

We have to keep in consideration that the BIOS/Windows in the tests are NOT tweaked for audio…

Just to note, as far as I can tell this is done by default under w10, I've not checked older OS's.Pictus wrote: Nvidia users may want to set the GPU to MSI(Message Signaled-Based Interrupts) mode https://forums.guru3d.com/threads/windo ... ts.378044/

FWIW, here's what I get:Ben H wrote:So you only tested ONE nvdia card?
That's a pretty flawed test then.
Ryzen 7 1800X, Asus Prime X370 motherboard, 16 GB DDR4 3200, Asus GTX 1070 with 411.63 drivers, Windows 10 Home 1803, AudioBox USB 96 interface

Thank you, that's almost the same latency I got with my old nVidia card.AdvancedFollower wrote:FWIW, here's what I get:

One time it was, then NVIDIA changed and now I do not know...
Anyway, can check with MSI utility v2 (run as administrator)

I have heard that for years, i.e. long before Ryzen: use AMD graphics with an AMD cpu and Nvidia graphics with an Intel cpu...

That's not really what it is about in this case. It's about the DPC latency penalty of using an Nvidia card, and applies whether you're using an Intel or AMD CPU. It's the Nvidia GPU driver itself that's causing more DPC latency than the AMD GPU driver.fluffy_little_something wrote:I have heard that for years, i.e. long before Ryzen: use AMD graphics with an AMD cpu and Nvidia graphics with an Intel cpu...

On my desktop, I had been running the built-in Intel graphics for a while on my i7 audio system. When I got a 4k monitor, the integrated graphics would only run the 4k monitor at 30hz with a lot of lag. So I bought an Asus nVidia GTX 1060. I noticed audio dropouts where I didn't have any before. I didn't perform DPC latency times while on integrated Intel. But the nVidia DPC times didn't look good. I just bought and put in a Gigabyte RX-550. My DPC latency times are less than a 3rd of what they were on the nVidia and the dropouts are gone.
Thanks team!
(I'll keep in mind the AMD vs nVidia latency times should I ever shop out another laptop.)
