How did you write your SDL program? Don't use any Setpixel functions.
Draw your pixels to a memory buffer/surface with the same pixel format
as the screen and flip that to the screen. Or try OpenGL. Use GL Arrays
if glBegin()/glEnd() is too slow.

The hardware shouldn't be a bottleneck if you don't use a system
older than 10 years or so. If you use OpenGL, you need an accelerated
driver of course, else it's useless.
