After the release of the Citrix HDX 3D Pro Tech Preview for XenDesktop 5 I thought it was time to upgrade my home “datacenter”. Bought a Core I5 with 8GB of memory and a Nvidia Geforce 430 GT with 96 Cuda Cores.
What I found out and should have checked before I bought the system is that for XenServer HDX 3D GPU pass-through features you need Intel VT-D and Nvidia SLI Multi-OS and both are a no go for my new system. To bad but those features would have doubled the price tag!
So what now? I just changed my test setup from virtual to physical. Installed Windows 7 with SP1 and ran the VDA Tech Preview installer. Ticked HDX 3D Pro and loaded the license file.
After some playing around I tried switching the HDX 3D CPU and GPU codec for rendering the ICA stream. I used Passmark Performance Test with the following configuration.
The results are very impressive. When using the XenDesktop HDX 3D CPU codec my client measures a datastream of almost 6 MB/s while the GPU codec doesn’t get beyond 2 MB/s. So while using the CPU codec the image quality is great the GPU codec saves almost 4 MB/s with the same quality.
