What are you using to measure FPS? Also, why do you want to double the frame rate?
GraphStudio in this case.
"Double Framerate" is a bit mis-named, in this case it just means that a 60i video produces 60p (proper video deinterlacing), and not 30p.
If the source is video material, and not film, you'll always want a 60p output for smooth movement. It doesn't actually "double" the frames, it deinterlaces the fields separately instead of only producing one frame out of both fields.

I have two concerns with using an approach like this:
1) Because of the niche nature of the decode/render steps the results are academic. Most users rely on DXVA decode and GPU DI (not sure if this is different) exposed through an EVR
interface for interlaced content playback.
2) Can only be used to rank NVIDIA's cards
Its not meant to be a "generic" approach. You asked how to quantify the performance of the cards, and thats how i would do it. Thats my playback setup, and i need a card with enough performance to use it. (and i can highly recommend it, you won't get any more quality out of a HTPC any other way).
madVR alone is fine for progressive content, but with interlaced content, nothing can beat hardware deinterlacing, and only way to get it with NVIDIA and madVR is my decoder (and CoreAVC, but thats for H264 only) - that i know of.
AFAIK, its not possible at all right now with ATI, unless the Cyberlink HAM decoder does HW deinterlacing, but i don't believe it does. (unsure, however). So you're either stuck with EVR if you want DXVA+HW Deint, or with software decoding+yadif+madVR.
Also, this is a NVIDIA thread, and i will always use NVIDIA myself (seeing how i also developed that decoder, would be silly to go ATI), so i don't really care how to compare an ATI card to this.
Btw, when letting EVR do the deinterlacing, it'll automatically reduce deinterlacing quality if it notices that the hardware is too slow. I'm not even sure however if it actually produces 60p out of 60i, thats only really detectable with visual inspection when running through EVR. If it doesn't do it, it needs far less performance, as most cards can produce 30fps..
