Does my Radeon HD 5570 really have DDR3 memory, or is it actually GDDR3?

Basically I see how most low end graphics cards from that generation down typically have DDR3 or DDR2 memory but are they really DDR3 and DDR2 like the type in our system memory?

The official ATI Site states:
"DDR3/GDDR5 memory interface"

So I'd assume it's either regular old DDR3 or GDDR5.

My friend insists that DDR3 is not capable of loading textures or other graphical artifacts. I think it can though I just don't have the proof to back it up.

You can always just use GPU-Z to pull the stats for your card.

Your friend is wrong, the 540M uses DDR3 and it can run most games, though slow.
The bandwidth of regular DDR is less than half.

DDR3 and GDDR3 are one and the same. Manufacturers just added a "G" to easily identify it as graphics card memory.

Your friend is wrong. The Nvidia GTX 295 is DDR3 and still one of the fastest cards today.

Turns out it is actually GDDR3. Still why are they all advertised as having DDR3. GDDR3 is technologically equivalent to DDR2 (Wikipedia).

This is NOT true. DDR3 refers to regular DDR3-SDRAM, while GDDR3 refers to a different kind of DRAM specific to graphics cards. GDDR3 is actually closer to DDR2 from an architectural standpoint, and provides for much higher bandwidth than DDR3.

GDDR3 is what's used as graphics memory.
DDR3 is a type of RAM

Consider how integrated graphics from Intel and AMD in their APU's run off of the same DDR3 the system uses. Like what one of the previous posts said, the main difference is bandwidth since graphics specific memory has much higher bandwidth than normal memory.
