Here I currently have P5Q PRO with graphic card as a Sapphire HD 4870 TOXIC 512 MB.
I would like to buy a 2nd HD 4870 TOXIC for a CROSSFIRE but my motherboard will operate 2 * 8X.
How many losses as a percentage of 16x will I have??
Taking into account this parameter what is the difference compared to an HD 4870 X2?
In this scenario my crossfire will still stood up?
Thank you for any answers.
Around 10 to 20% depending on the game
Thank you for you answer but on what basis have you done that calculation?
For you the crossfire toxic 512 is still up? 219 € and 389 € for the X2
By knowing what is running at 780 mhz? 750 mhz for the X2
I'm about to buy but I'm afraid that I will regret it later.
Apparently in 2048 the X2 memory above 1 GB is not operated by the OS, is what I have heard?
The only advantage for me is that the X2 could turn into 16 X
Thank you to me but because of the referrals I am confused, I do not know what to do.
The crossfire on P45 is on average 17.3% slower than X38 with differences ranging from 5 to 33%! We have here we must say a blow to P45 while technically there should not have differences. Indeed the management of the memory is slightly more efficient on X38, but surely not in such proportions!
Games & bench tested are newer and also expected to see much differences at home. I hope this is of concern to a driver or bios optimization alongside Intel (latent worries?), The P45 loses interest in crossfire. In any case, even though in absolute 10/15% are not so large that, in relative terms there are enough differences, making the switch to some games playable even to limit unplayable.
