In our review of the GTX 690, we got a little clearer picture of why the GTX 690 runs a PCIe 3.0
Doug, I read the article, and no, you didn't, you just stated that as a fact, and most importantly, didn't explain then or now why Nvidia is claiming
but have seen significant variation in signal timing across different motherboards and CPUs.
and telling its customers to enable PCIe 3.0 at their own risk (and what risks are those ?), but, get this, only for their GTX 680 and GTX 670 GPUs. The GTX 690 operates at PCIe 3.0. In fact, it's the card that will benefit the most from it.
What you said in the article you link to (GTX 690 review), was this:
Why not just ship it like that? There was a reason, we are digging deeper, but aren’t yet ready to discuss the results.
So, are you ready to discuss the results now ?
Why does Nvidia not find any problems with the GTX 690 on the X79 / SB-E platform ? This smells fishy and Nvidia is not explaining something. Why do AMD GPUs work fine at PCIe 3.0 speeds on the X79 / SB-E platform ? And why do Nvidia's drivers enable PCIe 3.0 on the X79 / SB-E platform for the GTX 690 and not for the GTX 680 and GTX 670 ?
Tom's Hardware, please investigate, this story does not add up.
