so in the end of it all, with all of the cell's power, how come pc games are still far superior graphically?

A few reasons:

- PC CPUs are easier to program for.

- PCs have more memory (even after accounting for memory intensive operating systems)

- PCs have much better graphics cards than the PS3.

 

 

so basically you're saying that ps3 will never pull off better graphics than the pc yes? i mean, memory and graphics cards can't be replaced on the system. i'm guessing processing power can only take you so far?

You are asking strange questions. You are saying that is not be better than what pc? is not better than mine, is it better than the blue gene? No. You don’t seem to know much about pc's.

 A pc has a flexible CPU that is not as powerful as the specific purpose GPU because that's how electronics work. For example analog circuits are instantaneous in their result, an analog differentiation or derivation circuit outputs instantaneous result(time zero response), an micro processor on the other hand need an algorithms and take several processor cycles to get a response that is not as accurate, the advantage of digital circuits is that you can change it purpose. There is also another example, ASIC( Application Specific Intergraded Circuits) are faster than microprocessor but as the name implies they are application specific, this takes us to GPU vs CPU. GPU are very fast because they are designed for a specific purpose, on the other hand the CPU can manage many different applications.

Processor’s performance does no depends on clock speed alone, the number of instructions per cycle, the word size and other thing have more impact on performance than clock speed. What happens is that clock speed is what Intel advertises and that’s all that people now about, for ages hi end processor where around 900mHz and they could output higher flops( mathematical operations per second) than more commercial CPUs, this bring us to flops. Flops it the real measure for processors, for example if one processor is very fats but can only add numbers in pairs it take longer for it to get to one million that a processor that can add numbers in groups of ten and so the processor with lower clock speed could have higher flops, so the slowest one has faster results. 

 

Anyway when you say PS3 or cell are not better than a PC, I don’t know what you mean, do you mean a Alienware ALX X-58 with  cores Extreme,  dual 2GB GDDR5 ATI Radeon HD 4870 X2 with CrossFireX and Quad GPU Technology and 12GB DDR3 SDRAM at 1600MHz - 6 x 2048MB? well you are right but that is a US$4,199.00 PC.
