Page 7: Conclusion

GeForce 9600GT is released on Feb 21, 2008. The card’s good performance per watt and performance per dollar really fascinated us. But after we read TPU’s NVIDIA’s shady trick to boost the GeForce 9600GT, we think we really should take a look inside.

Surf around the Internet for several hours, we find people around the world all discussing this matters. People focus on these questions:

  1. nForce mobo will automatically start LinkBoost?
  2. 9600GT runs better when we use NVIDIA mobo?
  3. 9600GT’s GPU clock rise when PCIe clock frequency rise?
  4. Other GeForce also have this issue?

    thanks,Original linkboost has been cancelled, all speculations are unfounded.

    nvidia is the best, but Ati is more better n yet cheaper than nvidia, just my opinion

    linkboost is not with us anymore but if you manually increase pcie clock, then there is hidden 9600gt boost :) so people should know about it. imagine oc version of 9600gt and you will increase pcie clock %10. What will be result? maybe GPU will start crashing. thanks for article.

    We already know about Asus. What we want to know about is XFX and Evga. The EVGA and XFX boards are rebadged boards while Asus is not.

    Another site talked about this before you guys posted it here. And he did a much more detailed test to see that it IS overclocking and it IS cheating on the tests. Because your comparing an overclocked card to non overclocked cards. It can’t get much more unfair than that. Why you decided to defend Nvidia on this is beyond me.

    TC: are you a dork? Did you even read the article? It clearly said that they wanted to get to the bottom of what TechPowerUp discovered so far. What is beyond me is your clear inability to read and understand the damn article before spewing crap out of your mouth.

    @ anonymous,
    no need to flame

    @TC, we are not defending… we just said what we know.

    You should do an actual benchmark test with the changes and see if changing the PCIe clock increases fps performance at all. Since the theory is that the PCIe bus is not bandwidth bottlenecked there should be very little performance gains, but if 3dmark scores are worth any value today then there should be a notable difference in some aspect of performance.

    Your results make me nervious about Nvidia’s intentions with PCIe 2.0. Also has anyone tested this with ATI cards?

  10. Hmm Says:

    Edit: I meant benchmarks* with the 9600GT since it has this issue (where 7000 and 8000 series don’t). If there is NOT a performance gain, then we can say that something else other than clock speed and bandwidth is changing with the frequency.
