This is the first comprehensive review available (review dated June 24th) I am aware of on the HD 4870 (512mb GDDR5). The review includes comparisons on the full gambit of current cards, including the GTX 280/260, 9800GX2, 9800GTX, HD 3870X2, and HD 3870.
The reviewer stated on another forum that "HD 48xx crossfire rocks..."
So, numbers can talk for itself. With the price tag $199(HD 4850) and $299 (HD 4870), RV770 is the BEST bang for the buck. Compare to GTX 260, A $299 only HD 4870 is a smarter choice. Yes, using this kind of word seems quite biased, but if you read all numbers from our review you will see my point.
Compare to GTX 260, HD 4870 is only 3/4 of its price while test items show the card have almost the same firepower!
HD 4850’s rival is 9800GTX, and we can see while their price keeps the same, HD 4850 have more than 15% leading.
But, RV770 also have lot’s of weak points. First, the card is HOT, i am afraid that if you are not going aftermarket coolers or water the card can not stand long.
Second, RV770 TDP is quite terrible. HD 4870 in stress mode almost can catch up with GTX 280. Is it still a AMD card? And the second Gen PowerPlay is not as good as AMD saids, seems can not lower the clock effectively.
|The huge impact of Radeon HD 4800 series force NVIDIA drops price for the Geforce 9800GTX to $199, and introduces the GeForce 9800 GTX+ at $233 which supports PhysX or other CUDA programs. However, it can’t threaten HD 4850 on price or performance with that price. HD 4850 has flooded out everywhere and HD 4870 is just around the corner. It will be launch on June 25th or July 8th.
Besides, we have benchmarked two or three HD 4800 in CrossFireX, and the the review is coming soon.
