I have old computer with GT8400 and with xbmc/vdr/dreambox. I would like to replace PCI 8400 card. On the market there are only 2 PCI passive cards from Zotac - GT610 and GT430 As far as I understood the main difference - the quantity of core (stream) processors - 96 for GT430 and 48 for GT610. Also there is variant with 512 MB memory and 1 GB.
So, I intend to use the best method for deinterlace of 1080i video - temporal spatial + scaling method lanscoz3 + HQ upscale. Also I intend to play 1080p video.
I saw qvdpautest and seems the GT610 PCI-E has better results than GT430 PCI-E. I close to buy GT610 PCI. But may be you have other opinion ? If yes, please share it
I have 2 Zotac 520 PCI for my older rigs that only have a PCI slot, and it has the same number of cores (48, the 610 is basically a rebranded 520). Very nice card.

But I will add that you’ll still need a decent CPU and other specs to get the best playback. Along with a decent player. What’s the rest of your specs?
The GeForce 405 card is a rebranded GeForce 310 which itself is a rebranded GeForce 210.
The GeForce 605 (OEM) card is a rebranded GeForce 510.
The GeForce GT 610 card is a rebranded GeForce GT 520.
The GeForce GT 620 (OEM) card is a rebranded GeForce GT 520.
The GeForce GT 620 card is a rebranded GeForce GT 430 (DDR3, 64-bit).
The GeForce GT 630 (DDR3, 128-bit, retail) card is a rebranded GeForce GT 430 (DDR3, 128-bit).
The GeForce GT 705 (OEM) is a rebranded GeForce GT 610, which itself is a rebranded GeForce GT 520.
The GeForce GT 730 (DDR3, 128-bit) is a rebranded GeForce GT 430 (128-bit).
From personal use, I can vouch that the 9500 GT PCI DDR2 (128-bit) performs noticeably better than the GT 520 PCI DDR3 (or GT 610) (64-bit).
I would expect the GT 430 PCI to be somewhat better than the 9500 GT, and significantly better than the GT 520/610. (However, the 9500 GT PCI is available with 1GB of VRAM. Some applications require a minimum of VRAM.)
I used a EVGA GT430 card in the past and a Inno3D GT610.
Performance in 430GT was much much better than the GT610.
Unless you can find a 630GT that works on your machine (which should match the 430 performance), I would recommend the GT430.
I need to revise my earlier response. Upon investigation, it seems that only the GT 430 64-bit was made available as PCI. This actually makes your exact question easier to answer, since the GeForce GT 620 card is a rebranded GeForce GT 430 (DDR3, 64-bit). The GT 430 PCI will be only slightly better than the GT 610 PCI. The cons are 49W vs 29W and if you need the card in SFF format, I think you’ll be out of luck.
In this case, the 9500 GT PCI should still be faster than either of them.
