help choose a graphics card and CPU for video acceleration

I'm going with a laptop for video editing and have a choice of 2 laptops an HP Elitebook 8460p with an AMD Radeon HD 6470m 1GB or an HP Elitebook 8460w with an AMD FirePro M3900 1GB Graphics.... what would be the best outta the two for fastest render times? I'm looking to stick with my current editor Vegas pro 13 which I've been painfully using without any GPU acceleration

Lastly what would you recommend for a CPU to get the fastest render times? I'm limited to a second gen i-series CPU so anything that generation will work just keep in mind I'll be running off of a 90w power adapter with non-switchable discrete graphics (integrated graphics is permanently disabled from HP without a way to switch it back on)

As long as you are using VPro 13 there is no gain for hardware rendering, because ot that you have to get the fastest CPU possibble.
With Pro 15 you get big advantage at hardware rendering with the newer Intell or Nvidia GPU's is my experience


but if I wanna upgrade my software should I go with the Radeon HD 6570m or FirePro M3900 graphics? I'm already getting the fastest CPU possible but in cases where GPU acceleration works should I get the 6570m or the M3900? I know the Radeon HD 6000 series graphics card works the best for rendering in Sony Movie Studio 13 suite but how identical is the M3900 to the 6570m?

The AMD Radeon HD 6470m comes from a lineage that's as reliable as any GPU ever has been with Vegas. My HD 6970 works well for GPU acceleration of video processing but I don't enable it for that because my CPU is enough for my formats. These cards can be used to render MainConcept AVC quickly with OpenCL. FirePro might work as well but there have been far fewer reports about those cards' performance over the years on this forum.

I didn't compare the exact specs of the 2 cards, as you can do that as easily yourself. There some good advice on what to look for from astar in this comment.

GPU acceleration is changing more in VP15 than in any version since VP11, so what worked best for VP11-14 may not work best now in VP15, or when it has finished maturing.

If possible, trial Vegas on both laptops. Measure both preview smoothness and rendering speed. If you can't, and everything else appears equal, I would get the Radeon.
