AMD Launches Radeon HD 4830 on Cheap

By - Source: Tom's Hardware | B 8 comments

AMD introduced the budget-friendly ATI Radeon HD 4830 graphics card this week to fill in the gaps of its new line of Radeon HD series..

The newly launched ATI Radeon HD 4830 offers excellent performance for gamers on a budget. Priced officially at less than $150, the card is already appearing at online retailers for just $109, after a $20 mail-in rebate, which puts it in direct competition with the Nvidia Geforce 9600GT and 9800GT.

The ATI Radeon HD 4830 is based on RV770LE silicon, which is essentially a crippled version of the RV770 silicon found in the ATI Radeon HD 4850 and 4870. The ATI Radeon HD 4830 features 640 stream processing units, 956 million transistors and a 256-bit GDDR3 memory interface. The clock speed and memory clock are set at 575 MHz and 1800 MHz, respectively, which are only a bit lower than those of the ATI Radeon HD 4850. Texture units total 32, compared to the 40 found in the ATI Radeon HD 4850, but both come with 512 MB of GDDR3 memory and a peak power consumption of about 110 W.

The ATI Radeon HD 4830 comes with support for DirectX 10.1, hardware video acceleration, CrossFireX, two dual-link DVI display ports, HDMI with integrated HD audio controller and DisplayPort. From early reviews online, the ATI Radeon HD 4830 seems to offer good mid-range performance with decent gaming capabilities. The performance of the ATI Radeon HD 4830 is nearly twice that of the ATI Radeon HD 4670 and it gives the Geforce 9800 GT a good run for its money.

For those curious about Far Cry 2 performance, the ATI Radeon HD 4830 can achieve rather playable frame rates with high image quality settings, although only at modest display resolutions. Some gamers may wish to get the ATI Radeon HD 4850 instead, especially those with older computers or larger displays. Overclocking is a risky alternative, but it would seem that the ATI Radeon HD 4830 can be overclocked to be nearly the same performance level as the ATI Radeon HD 4850, saving roughly $30.

    It beats the 9800GT hands down but it also consumes a lot more power; $50~$70 a year worth. I don't know why ATI won't incorporate 4670 power saving technology into 4830.

    I think the stream processors got cut down to 570 or so after a mistake was made in the core production...

    awww....the review could be by monday or tuesday.
    anyways, from guru3d it shows very similar performance to 9800GT.
    what's missing there is the crysis comparison between this 4830 and 9800GT, but i guess it could be 1 to 3 frame advantage by the 4830.
    yet, 9800GT is cheaper since it is around $100.

    I choose 4870, very better performance, just save more, not a lot, just more! :D

    really "it also consumes a lot more power; $50~$70" i pay 10C per 1Kw do u mean to tell me this card will consume 50,000-70,000 watts of power in year?

    According to Anandtech's (updated) test, 4830 consumes 17.8w/hr. more than 9800GT at idle and 38.2w/hr. at load.

    17.8*24*365=155928=$31 at $0.20/kwh

    My $50~$70 was from the old review before ATI released a matured BIOS and Anandtech updated their test.

    BTW, check and update your 4830's BIOS. ATI's earlier BIOS only enabled 560 SPs rather than the full the 640 SPs in the spec.

    AMD released this on the cheap? Not on this side of the pond! Gap from 4670 to 4830 is >€50, but can be less than €15 between the 4830 and 4850. Not such good value - my guess is that e-tailers are trying to shift old stock and the 4830s getting shafted in the process.
    Oh, and sorry for any typos - comment box is broken!
