Discrete HTPC GPU Shootout
by Ganesh T S on June 12, 2011 10:30 PM ESTOur first candidate has been in our labs for more than 6 months now. When we last took a look at the NVIDIA GT 430, it was an underwhelming performer. Have driver updates fixed the issues we had with the card? We are going to put the NVIDIA reference card through the paces and also through our new benchmarking methodology.
From the AMD side, we have 6450 reference card. This is the same card that Ryan took a look at earlier. We didn't cover too many HTPC specific issues in that review (except noting that the deinterlacing performance matched that of the 5570's), and we will correct that aspect in this piece.
AMD also provided us with a Display Port to HDMI adapter so that we could test out HD audio bitstreaming, and it worked without issues.
The second NVIDIA card we have in the list is the recently introduced GT 520. Ryan had again covered the launch, but without a detailed review. NVIDIA provided us with a retail sample of the MSI N520GT.
Rounding up our initial set of candidates is the AMD 6570 retail sample, courtesy Sapphire.
NVIDIA let us know that the GDDR5 based 6450 from AMD was not representative of what is available in the market. There is no passively cooled GDDR5 based 6450, and the core clocks of all the 6450s in the market weigh in at 625 MHz (compared to the reference card's 750 MHz). Keeping this in mind, we also added a DDR3 based MSI 6450 (quite late in the game) to the list of contenders.
The table below compares the listed specifications of all the contenders.

Let us now proceed to take a look at the HTPC testbed in which these cards were benchmarked.

All the numbers add up correctly now. Thanks for monitoring the comments and fixing the errors!Samus - Monday, June 13, 2011 - link
Honestly, my Geforce 210 has been chillin' in my HTPC for 2+ years, and works perfectly :)josephclemente - Monday, June 13, 2011 - link
If I am running a Sandy Bridge system with Intel HD Graphics 3000, do these cards have any benefit over integrated graphics? What is Anandtech's HQV Benchmark score?I tried searching for scores, but people say this is subjective and one reviewer may differ from another. One site says 196 and another in the low 100's. What does this reviewer say?

Give me a couple of weeks. I will be getting a test system soon with the HD 3000, and I will do detailed HQV benchmarking in that review too.dmsher99@gmail.com - Tuesday, June 14, 2011 - link
I recently built a HTPC with a core i5-2500k on a ASUS P8H67 EVO with a Ceton InfiniTV cable card. Note that the Intel driver is fundamentally flawed and will destroy a system if patched. See the Intel communities thread 20439 for more details.Besides causing BSOD over HDMI output when patched, the stable versions have their own sets of bugs including a memory bleed when watching some premium content on HD channels that crashed WMC. Intel appears to have 1 part time developer working on this problem but every test river he puts out breaks more than it fixes. Watching the same, content with a system running a NVIDIA GPU and the memory bleed goes away.
In my opinion, second gen SB chips is just not ready for prime time in a fully loaded HTPC.

Again, sorry for the slip-up, and thanks for bringing it to our notice. Fixed it. Hopefully, the gallery pictures cleared up the confusion (particularly the Noise Reduction entry in the NVIDIA Control Panel)stmok - Monday, June 13, 2011 - link
Looking through various driver release README files, it appears the mobile Nvidia Quadro NVS 4200M (PCI Device ID: 0x1056) also has this feature set.The first stable Linux driver (x86) to introduce support for Feature Set D is 270.41.03 release.
=> ftp://download.nvidia.com/XFree86/Linux-x86/270.41...
It shows only the Geforce GT 520 and Quadro NVS 4200M support Feature Set D.
The most recent one confirms that they are still the only models to support it.

Thanks for bringing it to our notice. When that page was being written (around 2 weeks back), the README indicated that the GT 520 was the only GPU supporting Feature Set D. We will let the article stand as-is, and I am sure readers perusing the comments will become aware of this new GPU.havoti97 - Monday, June 13, 2011 - link
So basically the app store's purpose is to attract submissions of ideas for features of their next OS, uncompensated of course. All the other crap/fart apps not worthy are approved and people make pennies of those.
