Radeon HD 4830: High-Speed, Cheap CrossFire

Sapphire's Radeon HD 4830

The Sapphire flavor of the 4830 comes in a small box, but it doesn’t skimp on the accessories:

Basically taking the opposite approach of the PowerColor model, Sapphire includes a host of adapters for its 4830 that allow the user to tailor the outputs to whatever he or she likes. The card sports two DVI outputs and an S-video output, but we have adapters for VGA, HDMI, composite video, and even component video. These options offer great flexibility for users with an older HDTV that doesn’t have any digital inputs.

In addition to the video adapters, the card comes with the requisite manual and driver CD. As another added bonus, a Molex-to-PCIe power adapter is included for folks with older power supplies. Unfortunately, Sapphire also chose to keep a CrossFire cable out of the bundle. This is a bit disappointing considering all of the other extras that Sapphire went out of its way to include.

Sapphire’s board is a unique animal and strays far from AMD’s reference 4830. Like PowerColor’s 4830, Sapphire uses a large dual-slot cooler in the place of the reference single-slot unit. Once again, this should provide increased cooling efficiency as well as quieter fan speeds.

The memory is Qimonda HYB18H512321BF-10 GDDR3 rated for 1, 000 MHz, which are the exact same chips used on PowerColor’s 4830 board. Sapphire chose to ignore the addition of any heat sinks or spreaders across the memory chips and we don’t think that decision will present a problem, seeing as how the card runs the memory 100 MHz below its rated speed.

Clock speeds in 3D mode are the exact same as the reference Radeon 4830's clock speeds, which are 575 MHz core and 900 MHz memory. Interestingly, Sapphire chose very low clock speeds in 2D mode to save power and reduce heat, with only 160 MHz for the core and 250 MHz for the memory.

    Great look into the 4830. Makes me want to buy a Xfire setup using these.

    If you couldn't get Tray Tools to work with the Sapphire card why not use another program? Instead of giving up and coming up with a lame conclusion.

    Also 993*2 doesn't equal 1885 and the 4870 is clocked at 750 not 780.
    Your sound and temp charts have FPS on their X axis.

    It's nice to see good cards from both companies, ATI and NVidia!
    And the price is not bad at all. The competition is so good!

    The chart on page two sais 4850 runs at 625 - but stock is 600, and 4870 at 780 - which is 750 stock ... so is the 4830 speed correct?

    Actually stock clocks on the 4850 *are* 625. :P

    I'm sure i saw that "4850 - smarter by design" article at anandtech first. or somewhere else... the name anyway not necessarily the article >.>

    I knew that the 8800GT wasn't that fast, but those benchmarks ahve to be wrong... Sorry Nvidia fan boy here. Bye.

    Um actually, the MSI runs at x16/x8 in SLI mode. If you instead got an evga 750i FTW motherboard, you would find it runs at x16/x16 in sli, thanks to its unlocked NF200 chip. the 750i FTW is not a reference nvidia board as the MSI is.

    LOL at 1680x1050, the 4870X2 IMPROVES when 4xAA is added? i smell a rat...
