Is System 256 more powerful than System 246?

[Arcade-Projects]

The myth of Namco System 256 being more powerful than 246 has been around for as long as I can remember but can't seem to find a proper answer. All we know is:

• System 256 uses the combined Emotion Engine and Graphics Synthesizer, EE+GS CXD9833GB, previously used on slim PS2 models, SCPH-7000X. System 246C still had the EE and GS separate despite the unified pcb design.
• System 256 no longer supports ATAPI commands. Any System 246 games that rely on these commands won't run on System 256 under normal circumstances.
• System 256 uses an additional expansion bus but only makes use of two boards with that bus.
• Time Crisis 4 has its EE+GS chip clocked higher than a standard 256 as well as additional ram. Clock speeds of both remain unknown.
• All System 256 games run at VGA res (I think).

I'm predicting a higher clock speed and/or more ram for System 256 but not as much to an extent as with Time Crisis 4. It wouldn't make sense to have the graphical capabilities of System 256 the same as System 246.
