boleh buat crossfire combine HD 3 series dengan 4 series!
CrossFireX works
One of our readers has found an interesting post on the Forumdeluxx.de website which shows two ATI Radeon HD 4850 cards paired up with a Radeon HD 3870 DDR4 card in CrossFireX.
Even the user that wrote the post, didn't expect it to work, but it apparently it does and without any problem. The mentioned trio in CrossFireX scores 14,180 marks in 3DMark06. Before sticking in the HD 3870 card, the system scored 12,300 marks under Windows Vista 64-bit.
It is a nice boost when you consider that we are probably talking about the first tests of this kind, and we are sure that the red team will do some more optimizations before the HD 4850 hits the store shelves.
Here is a picture of the system and you can find a desktop screenshot with the mentioned CrossFireX setup here. |

9.7 AMD has certainly engineered a winner with their Radeon HD 4850 series. This card, positioned in the $199 segment, reaches unprecented performance levels thanks to its excellent architectural improvements. In most benchmarks it can beat the GeForce 9800 GTX which is almost $70 more expensive. As we expected, AMD's RV770 GPU can not take on the GeForce GTX 280, but sometimes it comes really close. Due to AMD's new AA design, enabling 4x Anti-Aliasing is basically free now, so there is no reason not to use AA. In my opinion the sweet spot for this card is around 1600x1200 4xAA - never before could you run all games with a $199 VGA card at this res.
Even though it offers lots of performance the HD 4850 is quiet, actually it is the quietest card we ever tested in idle. Under load the fan ramps up but noise stays within well acceptable levels. A small tradeoff of these fan control settings is that the GPU almost reaches 100η under load, not critically high but a few η less would be better. AMD has also kept the power consumption down, the card offers one of the best performance/watt ratios on the market.
Since recent price drops brought the Radeon HD 3850 down to a mere $120, there is no way AMD can beat that card's price/performance. On the other hand that price drop lets AMD have a very nice product stack going from lowest-end up to $199 ($299 with the Radeon HD 4870 which we will test soon). NVIDIA has taken measures and announced their GeForce 9800 GTX+ today which will have higher performance at a lower price.
Overall I think the Radeon HD 4850 is the best card on the market right now if you are on a limited budget, yet want to be able to play all the latest and greatest titles out there. |
