However, the pixel clock is part of the GPU... Not sure why an SLI bridge would be affected by it let alone be required to use a high res + high refresh display. I have never heard before that a bridge itself has an actual pixel clock design spec. For a long time all GPUs has 400MHz RAMDACs that could drive 330MHz pixel clocks (and up to 400MHz unofficially), a while ago both camps went up to 540MHz capable GPUs because of the push to higher refresh rates.

Might be that these bridges can be detected versus normal ones and enable it in the driver. I know the previous ones could have LEDs on eVGA cards.

Agreed

...Why is the logo mirrored on the bridge?

What you said doesn't seem to make sense. I can understand if there are multiple revisions of the SLI spec for how the connections should be set up with their signal traces to prevent crosstalk and increase speed between the GPUs, but that would still have nothing to do with pixel clock on the bridge itself.

I guess the wording may need to be clarified. It is the CAPABILITY to run a higher pixel clock. The card dictates the pixel clock, these bridges can support a higher spec than previous gen versions, up to 540MHz. Higher resolution and refresh rates require higher pixel clocks, often over 400mhz.

I should also mention this may not be an EVGA only feature, there is just no way to tell. Most of the previous SLI bridges were spec'ed at 400MHz, including the first gen of EVGA PRO SLI Bridges.

The cool looking NVIDIA ones are also very likely the new pixel clock spec, same as EVGA V2.

It sounds like it has either more traces or something to support a higher data rate. I bet this would fix my SLI issue with my overclocked X-Star. I run fine at 96Hz but at 120Hz I get distorted colors and a blurry image. Single card runs fine at 120Hz.

Well if this allows be to run my x-star at 120hz instead of the 96hz then i'm sold guess i'll just have to wait till they're reviewed but it seems like fairy dust to me like monster cables that charge 200 dollars that due the same thing 10 dollar cables do. Very skeptical

@JacobF - A couple of questions if I may?

Are these new bridges designed specifically for the Titan X?

With true 4K and DP 1.3 on the horizon, will all this extra pixel power make a huge difference to 4K gaming at hopefully 120Hz?

Or will it just make it all run smoother?

I know my questions may be difficult to answer at this point, but from an R & D standpoint, there must be some evidence to support the move to greater pixel density and the hardware required to push 4K to new higher levels??? wink.gif

Yup, likely. If it works in single card it is likely the bridge.

The bridge is not about performance, at least to my knowledge, it is about compatibility. On a bridge under your needed pixel clock you may get screen blanking or strange visual artifacts while in SLI. Today its rare to see this because it requires a very specific set of variables... like high resolution + 120Hz and specific games.
