Our 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.
| Discrete HTPC GPUs Shootout Contenders | |||||
| NVIDIA GT 430 | AMD 6450 [GDDR5] | MSI GT 520 | Sapphire 6570 [DDR3] | MSI 6450 [DDR3] | |
| AMD Stream Processors | 160 | 480 | 160 | ||
| NVIDIA Stream Processors | 96 | 48 | |||
| Core Clock (MHz) | 700 | 750 | 810 | 650 | 625 |

| Memory Clock (Data Rate) (MHz) | 900 (1800) | 900 (3600) | 900 (1800) | 900 (1800) | 667 (1333) |
| DRAM Configuration | 128b 1GB DDR3 | 64b 512MB GDDR5 | 64b 1GB DDR3 | 128b 1GB DDR3 | 64b 1GB DDR3 |
| Max. TDP (W) | 49 | 27 | 29 | 44 | 20 |
Let us now proceed to take a look at the HTPC testbed in which these cards were benchmarked.
Thank you guys for catching it so quickly.
Take care,
Anand
i just pointed out a resemblance i noticed as a matter of fact.
http://en.wikipedia.org/wiki/Swastika
"Hitler"
Most people think of Adolf
"swastika"
Most people think of Nazi
I'm of Jewish decent... the pic didn't offend me in the least bit, nor my friends.
Jusy saying.... ;)
I see no harm in accidentally arranging something in a Swastika :p
and on that notes.. There is a company in my home country that has been using the swastika as the company logo for over hundred years:

The way the western world depicts adolf hitler, nazism and everything surrounding that part of history is far from reminding anyone not to make that mistake again, as the main message is "nazi evil, hitler evil, us good guys, us not like them".
Anyone ever wondered what difference there is between Gestapo and the Patriot Act ? - oh right it doesn't target jews so it's fine ... lol
