They are referring to graphics cards mate............. by unlocking more pipelines it allows more bandwidth from your card giving you better performance

The more pipelines a card has, I believe the more graphics operations it can do per clock cycle. That's why a card with more pipelines will usually out perform one with less, even if it's got slower clock speeds.

Pipeline
Computer processors can handle millions of instructions each second. Once one instruction is processed, the next one in line is processed, and so on. A pipeline allows multiple instructions to be processed at the same time. While one stage of an instruction is being processed, other instructions may be undergoing processing at a different stage. Without a pipeline, each instruction would have to wait for the previous one to finish before it could even be accessed.

To understand the benefit of a pipeline, imagine that a car manufacturing plant had to wait for each car to be fully completed before starting on the next one. That would be horribly inefficient, right? It makes much more sense to work on many cars at once, completing them one stage at a time. This is what a pipeline in a computer allows. Pipelining, as it is called, often keeps around six instructions at once in the processor at different stages of processing. Pipelines can be used for the CPU as well as for accessing memory (DRAM).

Quote:
Pipelining is a technique used in advanced microprocessors where the microprocessor begins executing a second instruction before the first has been completed. That is, several instructions are in the pipeline simultaneously, each at a different processing stage.

The pipeline is divided into segments and each segment can execute its operation concurrently with the other segments. When a segment completes an operation, it passes the result to the next segment in the pipeline and fetches the next operation from the preceding segment. The final results of each instruction emerge at the end of the pipeline in rapid succession.

Although formerly a feature only of high-performance and RISC -based microprocessors, pipelining is now common in microprocessors used in personal computers. Intel's Pentium chip, for example, uses pipelining to execute as many as six instructions simultaneously.
Hope that helps... /\\

Sorry to intrude, but what about the unlocking part? All I know is that certain GPUs can be 'unlocked' to take advantage of all their components. So you'd be buying a cheaper card that's just as capable as its more advanced version (like the guide to unlock the X850Pro to the X850XT/PE) if you unlock all of its features.

Well i could be wrong but can you not unlock pipelines to the 6800GT version.

The PCI-E 6800s don't like to unlock, it rarely ever works. The AGP versions on the other hand, will easily unlock.

Yeah, that card looks like a GT or an Ultra, which are the top tier models of the 6800 line. Unless its a 512MB 6800 Vanilla....
But yeah, when they make the cards, they first built the GT ( I THINK)
Then afterwards, they created the Ultra edtion, and upped the clocks.
THEN, after that they released the 6800Nilla, and locked some things down, then sold it for way cheaper, which is great for us people, because we know how to pump every last ounce of performance out of our pc components
