It can execute over 3,000 lines per second at 4 MHz! Although of course, graphics-heavy statements can slow this down to about half that. Check out our [[Practical Speed Tests]]. |
| Now, compared to a C64 running at 1mhz, why is it so fast? You would expect it to top out at ~800 lines per second since it's four times faster. First, the SD-8516 does not experience the register pressure of a 6502. With more registers available to the programmer, the code size is smaller, and therefore faster. | Now, compared to a C64 running at 1mhz, why is it so fast?
