ATI R600 - 19 shader units?

[TroubleM]

Here in the quote from Beyond3D:

• "Richard's talk concerned D3D10 performance on upcoming ATI hardware. Confirming it was a unified part in hardware, he asked the assembled crowd to think of it as a 17 shader unit part, so that he wouldn't have to give the game away before it was announced officially. Surely he understands we know already that it's 19? Regardless, he forged on."

The article about the upcoming DirextX10 is here Link.

So what does this mean? I always thought that the number of pipelines/shaders would be an even number.

R600 is Unified architecture

Read it again: "so that he wouldn't have to give the game away before it was announced officially."

He used a hypothetical odd-number to squish the possibility of any speculation on what the real specs would be.
