Best Nvidia CUDA Card for HQPlayer

genuine question: what advantages are there for upsampling redbook (or even DSD64) to DSD512?

among others this will depend on your DAC. If your DAC performs better at DSD512 (e.g. T+A DAC 200), you will have a sound quality advantage. It will depend on the combination of the components you use, which "path" will give the best sound quality.

Challenge with those 12 GB cards is that the case you describe takes very close to 12 GB of RAM. So if there are any other processes using the GPU (for example for display output), or when convolution is in use, then it can easily run out of RAM. This is why I recommend to get 16 GB models when buying a GPU.

 

For other filters, this is not nearly as close.

 

@Miska Hello Jussi thanks in advance for time that I could dedicate to myself.

I have an I5 12400 with 16Gb DDR 3200 running Ubuntu 22.04.04 with your low latency kernel running HQP Desktop 5.7.3. This PC is connected via Ethernet to an rpi4/NAA connected with USB3 to the Cyan2.

This PC works perfectly in DSD256 upsampling with Cyan2 correction using N1/Nx poly-sinc-xtr-short-lp/mp Filters with ASDM7EC-light modulator.

Unfortunately with the correction it fails to work properly at DSD512 with the same filters and modulator. If I deactivate the correction it works perfectly on DSD512 but also DSD1024 (see the screen-shot), but using the AHM7EC5L modulator. Temperatures remain normal thanks to the Noctua NH-D9L.

My question is whether adding a GeForce RTX 4060 16Gb DDR GPU can help the CPU achieve DSD512/1024 resolutions with the Cyan2 correction. I don't use Convolution.

Considering the cost of around €500-600, is it worth adding the GPU or is it better to just change the CPU and switch to I9 14900K?

Thanks very much indeed for your suggestion

Best regards

Gerardo

I don't have any RTX 4060, so I cannot comment. But my guess is that it won't do it at DSD1024...

IIRC, 14900K cannot do DAC correction at DSD1024 either. But I cannot confirm right now. But on Windows, correction at DSD512 works for me with RTX 2080Ti at 44.1k x512, but not with 48k x512 (i9-10900K). So this can give some ballpark figure.

I can do DAC correction, with lesser CPU, and GPU offload, for 1024x with the hybrid EC modulator.  I am sure you know this but just for others who might read later.  😊 

RTXa5000 🤭

Chapeau 👏👏👏

Just to clarify this is with the hybrid AHM EC modulator- I suspect alot of other folks can as well.

My small I5 12400 with 16Gb DDR3200 under Ubuntu 22.04 can do 48x1024 with AHM EC modulator but without correction for Cyan2. For this reason I was wondering It adding a CUDA GPU would allow the correction to be used.

It can also do 48x512 with heavy filter N1/Nx and ASDM7EC series

Did you try block size of 4 for example?

1-4 is required for me to do 512x with heavier modulators and DAC correction enabled.

Thanks for suggestion but unfortunately even setting block size to 4 doesn't work. Stutters every 10-15 seconds 😞

I have an NVIDIA GeForce RTX 4060 Ti 8Gb with i914000, this is what I can play on DSD1024 with no DAC correction or convolution enabled. For DSD512x48 I can support more demanding combinations with DAC correction and PEQ enabled.

Can DO with GPU 4060ti 8Gb

@MoisesWhat utility is that?  Some form of HTOP?

Thanks a lot for info but I believe it Is more inexpensive to upgrade CPU at I9 13900k or 14900k.

I9 13900k costs 450€ more or less, while RTX4060 16gb costs more than 500€.

I9 14900k costs 550€

Yes, that’s best choice, then if you want extra boost GPU

I have updated to NVIDIA GeForce RTX 4070 Super with i914000,

Can play (44.1 to 192)

DSD1024x48 

1x/Nx Sinc-M

ASDMEC7-ul

Not much load on GPU

Will test more, but it seems a good choice on cost/performance, specifically for ITX build.

 

 

Good news!

Just a clarification: which I9 do you use?

I'm looking to upgrade my PC

Thanks in Advance
