Sapphire HD4830 Graphic Card Review

Sapphire HD4830 Graphic Card Review

The ATI HD4830 card range, I know it’s kinda late to review this model since most sellers by now aren’t carrying it anymore as would-be buyers are already aiming for the recently released HD4770.

Well, that’s not gonna stop goldfries from reviewing the HD4830 cards. They’re much cheaper than the HD4850 and packs quite a decent punch. You could get your hands on some used unit should you need an upgrade.

The Appearance

I have with me are 2 variants of the Sapphire HD4830. Both cards look identical at first glance but upon close inspection, you’ll see that the PCB are of different shade.

One is has a touch of cyan while the other is dark blue. They also come with different output port.

Operating Temperature

Furmark was used for graphic card stressing.

  Idle (°C) Load (°C) Stress (°C)
Temperature 44 66 88
Temperature (OC) 44 69 92

Readings were taken when ambient temperature was around 27°C.

– Load, Furmark was run for 1 minute at 1680×1050 with 4xAA.
– Stress, Furmark was run under the Stress Test mode for 5 minutes.

Power Consumption

Please note that the numbers below indicate the wattage for the entire system, not the graphic card alone.

System Power Consumption Idle (w) Load (w)
Sapphire HD4830 44 193
Sapphire HD4830 OC 44 206
ASUS EAH4850 TOP 73 239

Seems to be quite power hungry, despite it being a lower range graphic card. Being of the RV770 core, I’m not surprised since the HD4850 is a really hot monster with quite significant power drain.

Readings taken with Gigabyte’s P-Tuner software.

I didn’t manage to take power consumption readings for CrossfireX mode, based on the readings – it’s not going to be something low. 🙂

So is the card good? Yes!

As you can see from the results, it’s not far from the HD4850 and it consumes lesser power – it’s certainly a more cost-effective option.

It’s just too bad they don’t bundle a Crossfire cable along with it.

*psst HD4770 review coming out in a few days. be sure to drop by, ok? btw I’m selling off my Sapphire HD4830 when it comes back from RMA. Remember to check Goods Garage. 🙂

**ok ok. update – the HIS HD4770 that I ordered were faulty. ALL 3 of it!!!! [email protected]()#$(*&@#$(% ……… sorry guys, I’m damn lucky. so basically I have 4 cards gone to RMA within a month without me even stressing them badly. Really lucky. Latest update was that it didn’t work with Vista 32bit. Tested with Vista 64bit and XP and it worked fine. So it looks like driver issues. 🙁

***btw I’m selling off the Sapphire HD4830, here’s the thread..

  1. Hi,
    Would like to know if i pair this up with Pentium Dual Core 3.0 Ghz,
    will it run with its full potential or most probably will it be bottle necked due to the processor?

    It should be just nice. I wouldn’t worry about it that much.

    I’ve compared my 2.53ghz vs 3.6ghz setup on GTX295, the are differences but personally it’s not something I would worry about. 😀

  3. Now I only know what’s the difference between those 2 cards.

    As me and my bro bought 2 HD4830 together at LYP some day back and we do pay at the same price which is RM375.

    His 4830 is the dual dvi and mine is the dvi,hdmi,vga.

    Guess I’m the lucky 1.

    Yeah, when i bought that time both sellers say is HD4830 only. one seller from Klang and another from around Ampang area.

    i guess both didn’t even know there’s difference in the HD4830 variants. after I bought then i was taking photo then i see card differ a little. then check the core / mem and saw the speed variance. 😀

  5. samuel here =D, man the HD 4770 was a disappointment! really wish it could work on 32 bit OS…my current card is killing me!!! =( hope after the RMA it will work fine on 32 bit OS….xD anyways, if HD 4770 doesnt work on 32 bit OS, which other graphic card u’ll recommend?

    Sam – the HD4770 is now working fine!

    The HIS HD4770 refused to work on me, even on the distributor side. However the Sapphire HD4770 works just fine. 😀

    It wasn’t RMAed, it was just exchanged with a little top up. Will pass it to you (or your dad) on Tuesday!

  7. really? WOOOHOOOO thats a great news! finally i can throw the old junk away!!! hahaha anyways, thanks xD
