Although the clock rate is slightly higher, any software making heavy use of the lower 16 KB of RAM will run slower on the NTSC Spectrum, since the proportion of time during which memory is contended is greater. This is a result of the NTSC Spectrum's need to render the display at a higher frame rate (60 Hz instead of 50 Hz). | Although the clock rate is slightly higher, any software making heavy use of the lower 16 KB of RAM will run slower on the NTSC Spectrum, since the proportion of time during which memory is contended is greater.
