Best CPU for hqplayer


Recommended Posts

Thanks Miska. I was mistakenly thinking "higher sampling rate = harder on resources," so this makes sense!

For -2s filters (including ext2) it is true to some extent since it affects the intermediate rate. For other cases the output rate is primarily which defines the load in combination with conversion ratio.

So sampling rate is important with ext2.

 

However i am confused at to which modulator should i use.

 

ASDM7 allows me sample rate upto DSD256

However, ASDM7EC only allows me sample rate upto DSD64.

 

Which one would you recommend in this case?

Whichever sounds best.  Your dac may have a sweetspot that "overrules" the logic of the rate/modulator combo.

Could you do... DSD128 using ASDM5EC?

 

Might be a good balance. To me, I prefer the EC modulators at lower bitrates. I can do DSD1024 at ASDM7 but 256 at ASDM7EC sounds more natural, organic, and better renders the "space" in the recording better, IMO.

 

Also, make sure Multicore is just grayed (not checked) and that Auto Rate Family is fully checked. You sacrifice a tiny bit of overall rate to make the math substantially easier by staying in the same 44/48 rate family. I can't tell a difference on that end, so I do what's most efficient for my CPU at that point.

Thank you for your reply.

 

i can stretch ASDM7EC to DSD128 as well. But since my intel nuc starts its fan, i thought maybe its a little hard on it.

Hence i dialled down a bit to DSD64. I like the sound but not sure which is technically superrior.

 

Your reply suggest the EC modulators are superior than the simple ones and will out-perform them even at lower sample rates.

 

I have never tried ASDM5EC. How does it stand against the ASDM7EC technically speaking?

 

 

Also to be clear, I have only been using the "44.1 x n" so far and haven't ever tried the "48 x n" setting.

Truly when it comes to ASDM5 vs 7, it's a personal preference. I gather "7" is more technically superior, it's more complex and requires more horsepower but that doesn't mean it will always be the preference. That falls to the listener.

 

And yes, if your NUC fan is coming on, you're pushing things a bit, but I wouldn't take that as a sign I needed to back it down - unless the fan is obtrusive and the area isn't properly vented. 

 

And I will admit, on 5 vs 7 - I haven't listened to 5 in a long while. 7EC has been one of the settings I hold fixed, because my setup can do it at DSD256, so I play more with Conolution and the filters themselves. Have to say I should probably revisit 5EC because I don't necessarily recall how it sounds by comparison. I just know that in my system, which I feel is pretty transparent - 7EC at 256 with either Sinc-L, EXT2 or XTR-2S - instrument timbre sounds convincing, bass has heft and believability without being overcooked, and the recording space/venue seem to just replace the far end of my room while the music is on.

Thank you for your reply Todd.

 

I think for now I can stick to poly-sinc-ext2 with ASDM7EC at 44.1 X 128.

I checked my CPU usage and the %age value of Processor utilization mostly averages 65% approximately.

 

I guess this setting will be technically superior to ASDM5EC at 44.1 x 256.

So currently I'm on poly-sinc-ext2 with ASDM7EC at 44.1 X 128.

 

I checked my CPU usage and the %age value of Processor utilization mostly averages 65% approximately.

 

I guess this is fine and tolerable for my intel nuc.

 

So, I should stick with this or go DSD256 (44.1x256 with ASDM5EC)?

Well, I would personally rather use ASDM5EC at DSD256 than ASDM7EC at DSD128. The EC feature makes ASDM5EC perform pretty good too, and in some cases it may be preferable anyway, like with ESS Sabre based DACs.

 

But give it a listen and decide yourself.

Thank you very much, Miska.

Just circling back around on this - I swapped my 2070 Super in for the 1650 that normally sits in my HQP PC and I was able to successfully run Sinc-L at 44.1/48 rates in combination with ASDM7EC + 256/48.

 

So, when GPU prices come back down to earth in 6-9 months, or if I find a solid used deal, I know what I can do for my next upgrade :) I swapped the 2070 Super back to my gaming PC because the 1650 wasn't going to cut it in that role.

I am using a T+A DAC 8 DSD with "poly-sinc-ext2 and ASDM7EC at 48 X 256", would you have another configuration recommendation for the T+A DAC 8 DSD?

No, this is very good one. You can also try sinc-S with 48k DSD and adaptive output rate enabled. Also poly-sinc-short-mp is always worth trying (pretty much opposite of sinc-S).

Some load figures for the Ryzen 7 5800X with the new special build of HQPlayer 4 Desktop running on Ubuntu Desktop 20.04 LTS:

Very nice figures, even more considering HQPlayer is running on your desktop with quite a few background task and not on a dedicated environment. The extra CPU headroom is most welcome.

Thank you, great job.

Just 7 tasks total running when the screenshot was taken. Of which one is ssh server for the terminal connection and another one is htop to display CPU loads. That leaves HQPlayer + Client and three other tasks (X server, window manager and desktop compositor).

 

I had HQPlayer Client running on both Linux and on macOS.

Client and terminal with ssh connection to the Linux machine running on Mac Mini M1 under macOS.

 

P.S. Part of this performance is thanks to the G.Skill DDR4-3400 CL16 RAM...

 

 

Hi Jussi,

 

Congrats for the perf of this build.

Would you have a typical config (mobo, memory, aso)  you would like to share with us ?

Thanks in advance :-)

Built into Fractal Design Define C case. Seasonic Prime Fanless TX PSU, which I will swap with Prime TX-1000 from another machine when the new Radeon RX 6800 XT GPU arrives. CPU cooler is bequiet Dark Rock Pro 4.

Hey all :) any of you got a system with HQPlayer capable of upsampling DSD64 5.1 -> DSD128 5.1 with ASDM7EC?

on my System an AMD Ryzen 9 3900x with RTX2080ti and 32gb RAM i get with ASDM7EC very stuttery playback with ASDM7 it works 99% some klicks like on a dirty vinyl :) my DAC is an Okto Reserach DAC8Pro i use the Ryzen as testbench (Win 10) on the same machine is roon core and HQplayer installed... then over ethernet to an ALLO USBrige with ropieeeXL with HQPlayer NAA and then to the DAC8Pro via usb.

For consistency I'd get started with Ubuntu Desktop 20.04 with their lowlatency kernel or my custom kernel, and HQPlayer 4 Desktop (AMD optimized build in this case). And then first check if it works without a NAA. And then when things work without a NAA, you can add NAA.

 

Otherwise you can easily have a bit too many variables in the system to figure out where the bottleneck is.
