crossfire 4870 between 4290 onboard

[AxelF]

I have said many times that among ATI crossfire video card integrated with a dedicated card as long as it is the same series, just got an ASUS M4A89GTD PRO with onboard video 4290. I brought my 4870 home to observe if we might crossfire them. It was a classic. Try to follow the instructions, but not at all saw a crossfire alternative in the Catalyst Control Center. We were able to see both cards scheduled in device manager and had the catalyst control 10.7. Is not it possible that these two fires or were doing wrong?

As per my knowledge I said, the reason is useless to try it because even if I could, the 4870 can do in a single cycle of what the 4290 has more to do. The 4870 would make a frame then sit back waiting for 4290 to complete their framework, previous to it can make its next frame. This adds a lot of latency; you get a lot of delay and significantly more CPU load (as the drivers are software based) and not worth cabins. I hope this information will help you.

Hybrid crossfire is designed for smaller budget. When people who only had $ 50 to spend on a graphics card that could pair the card among the IGP and get more out of either solution alone. 2x $ 50 card will not have the same performance as a $ 250 card .... not how it works. In the best case, SLI or Crossfire will receive about 1.8 times the performance of each card used in the pair - mixed crossfire is a little different. In these cases you can wait for about 1.6 x 1.5 the performance of the slower card in the pair. In these cases you can wait for about 1.6 x 1.5 the performance of the slower card in the pair.

Happy to hear you like your 4290, you are able to crossfire a 4870 and 4290, and you will observe considerable gains in most games. In fact Crossfiring a 4870 and a 4290 will sternly limit the 4290 so that it will be like Crossfiring 2 4870s. As well now sell your 4870 and put in another 4290 if you require. Crossfiring a 4870 and a 4290 is going to bring the 4290 down to role as a 4870 but this is at rest to your benefit as 2 4870's simply beat out 1 4290....and its costing you not anything.

Well thank to you all. By the way reminds me that I help with the questions I had about my HD 3300. Finally got a video card (as I said 4870) and now I be able to play BF2, BF Heroes and 2142. I do not like any of them, but I specifically remember not to play with them (black filtered) with Windows XP and formatted with Windows 7 with 3300. Once I have the 4870 all was well. Thanks again! I at rest think I am going to try it any another time I am over at home just for the hell of it. See if it helps benchmark numbers.

Fundamentally to answer your inquiry - no it won’t work, and even if it did it would successfully time-consuming. Pairing an HD 4870 among a 4290 would be greatly like renovating a glass of water into the ocean since you think it will make the ocean any deeper. The 4290 is based on RV620, which is some like the HD 3470, except slower. You are saying about a core of 40 shader processors compared to one in 800. If it is to over clock the HD 4870 at about 80 MHz would be adding extra presentation than I could ever hope to gain from crossfire with them.
