If we're talking about the future, DACs based on GPU?

Folks, folks, a guy who studies chips and also a DIYer told me at dinner, speaking of the FIR stuff, or DACs we usually talk about, a $40 FPGA which runs at 200MHz is about 30 times better than a i7 at 4GHz, and a GPU doing FIR is 100 times better than FPGA, but nobody uses GPU now, so some DACs must be designed in this Avant-garden.
 
Hi,

GPU's are now general purpose units, not graphic processing units.

The idea of most current integrated chipsets is the GPU can
help the CPU, as well as implement the graphics processing.

CPU's have replaced by APU's, accelerated processing units.
The accelerating parts are the GPU's.

Unfortunately my knowledge in this area is very sketchy.

But FWIW my seemingly mundane integrated graphics laptop:

AMD A8-4500M APU with Radeon(tm) HD Graphics (4 CPUs), ~1.9GHz

Can run the Doom3 demo at 130 frames per second, with everything
turned on full. When Doom3 came out nothing could run it on full AFAIK.

Such is the onward march of progress.
