Closer Look:

Sapphire has chosen to break from the reference design with this card to show how this separates it from the rest of the pack. Sapphire has built their HD 4830 on a blue colored PC Board with an aftermarket heatsink. The Sapphire HD 4830 uses the same RV770 core that is used on the HD 4850 and HD 4870 cards with lower clock speeds and crippled shader and texture units. This also will help keep the Sapphire HD 4830 card running cooler unlike its bigger brothers that were plagued by high temperatures.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Sapphire HD 4830 video card has two DVI ports, which support Dual Link DVI and multiple displays, and an S-VIDEO port for component video out. The HD 4830 requires a single 6-pin PCI Express power plug to provide the juice needed to push the limits of gaming and other tasks. On the top spine of the PC Board are two tabs which are used to connect this card to other compatible cards in a CrossFireX multi-GPU setup. You can connect up to four cards for QuadFire if you have a supporting motherboard.

 

 

As I stated earlier the HD 4830 uses the same RV770 core as its older brothers the HD 4850 and the HD 4870. The Core however runs at a slower 575MHz and only has 640 shader units unlocked instead of 800 on the other two and 32 texture units instead of 40. The memory is 512MB of GDDR3 which runs at 900MHz (1.8GHz effective) all on a 256-bit memory bus. The memory on the Sapphire HD 4830 card is manufactured by Qmionda and is model # HYB18H512321BF-10 which is rated up to 1000MHz so there may be some good overclocking going on.

 

 

The cooler added to the Sapphire HD 4830 is a dual slot type design that uses a copper core and aluminum fins to help quickly dissipate heat. There is a large fan which forces air over the fins dropping temperatures and keeping the critical parts cool. This is the same fan we saw on the big brother HD 4850 card from Sapphire and it dramatically reduced operating temperatures so I am pleased to see it on their HD 4830 as well.

 

 

Now that we have seen the glory how about we start the testing phase.
