A3640 VS WarpEngine

[alexh]

There is a massive speed difference because the A3640 cannot use one of the best features of the 040 which is BURST. Almost 1.6x clock speed increase + burst support made the WarpEngine much faster.

An A3640 is many times faster than an 030x50 due to architectural differences, bigger caches etc.

There should be a formula that would give me precise answers when comparing processors

There is. It's called benchmarks

As you can see the WarpEngine is anything between 1.25x and 2x faster than A3640 and 3x faster on RAM because of burst access.

Well it HAS RAM where as the A3640 doesnt!
