This is a rough estimate of the increase in the overall power of the Dreamcast listed at standard, non-standard, and non-accomplished speeds. Data here is based off a combination of data on the machine collected from:
http://www.emulator-zone.com/doc.php/dreamcast/
and
http://www.segatech.com/technical/
Again, this is a rough estimate based on incremental percentage increases. This is not totally accurate, since faster RAM, faster cache, and so on actuall improve performance further than spec (2%-5%), but this is just a rough view to see how fast your Dreamcast can fly:
Normal, 100Mhz FSB Dreamcast
CPU @ 200Mhz
GPU&RAM @ 100Mhz
CPU capable of 10,000,000 polygons per second
GPU capable of 7,000,000 polygons per second
800MB/s FSB transfer speed
1.400Gflops, 900Mflops sustained CPU
360MIPS
Overclocked, 120Mhz FSB Dreamcast
CPU @ 240Mhz
GPU&RAM @ 120Mhz
CPU capable of 12,000,000 polygons per second
GPU capable of 8,400,000 polygons per second
960MB/s FSB transfer speed
*1.680Gflops, *1.080Gflops sustained CPU
432MIPS
High Overclock, 133Mhz FSB Dreamcast
CPU @ 270Mhz
GPU&RAM @ 133Mhz
CPU capable of 13,300,000 polygons per second
GPU capable of 9,310,000 polygons per second
1024MB/s FSB transfer speed
*1.862Gflops, *1.197Gflops sustained CPU
478.8MIPS
Extreme Overclock, 150Mhz FSB Dreamcast
CPU @ 300Mhz
GPU&RAM @ 150Mhz
CPU capable of 15,000,000 polygons per second
GPU capable of 10,500,000 polygons per second
1200MB/s FSB transfer speed
*2.100Gflops, *1.350Gflops sustained CPU
540MIPS
Specs to reckon with indeed. For comparison, the PS2 has a powerful FPU (can float at 6Gflops+), but can only generate 450MIPS.
