HD 4830

[Rick James]

Anyone running one? How do you like it? Any complaints?

 

[way2fast91]

Love it, upgraded from 7600 GT KO. For the price, it has been reliable and eat through most games I throw at it on high settings, althought I don't play FryCry2 or Crysis, mostly Fallout3, L4D, Oblivion, older SW games. Video quality is great on my 1080p monitor with smooth playback. I have the Sapphire HD4830, prior to the HDMI revision. Running it at 690/900. Tried oc'ing the mem but had issues with artifacting in games. I think it was a great card for the $120 or so I paid, so for the current price of $75-80AR I think it's a steal for value gamers.

Its cheap, strong engine and quiet. The over all performance is solid. Been running
one in a customers PC. He games all the time. Never hear him complain either. So
I guest it a hd worth keeping or using unless you can afford a higher end card.

I have the same card as you. I cant OC the memory past where i'm at or all games and apps artifact slightly. My GPU must have been from a 4870 as its gone up to 760mhz and played a few games. I don't trust it that high though.

I play all my games maxed out at 1680x1050 with 2x/4xAA. Source games are the best with this GPU as you are typically CPU limited no matter what. I play DOD:S all maxed out with HDR and 8xAA/16xAF and motion blur @ 90-200fps. I run mat_queue_mode 2 of course. If that isn't power i don't know what is.

I paid $99 for mine. I think it was just as good of a GPU purchase as my 8800GTS 320mb just a year ago for $79.99.

Had my Sapphire (pre-HDMI version) HD4830 since early Jan. It replaced an 8800GTS 640MB card that went to another machine. Runs WAY cooler, more efficient, better overclocker, better performer on all fronts. Mine is currently at 690/1000, though the auto-tune thing in CCC set it to 800/1200, which was ridiculous. Start getting memory issues as I approach 1100. Paid $85 after rebate and I actually got the rebate within a month, which was nice. Great "budget" card.

 

[TurtleCrusher]

Three guys with the same pre-HDMI version saying good things, looks like we have a winner.

Just be aware that the catalyst 9.3 drivers will not function for Folding @ Home, unless you are hacking up the files.

Maybe Standford will update their software or ATI will fix it, but it is clear neither were communicating with each other for the release of the 9.3 Catalyst.

Thanks guys. I ordered two open box Sapphire 4830's for 72 dollars today from the egg. Should be fun in Xfire

well the whole point of running 2 cards is so you can increase the settings. at 1920x1200 with 2 512mb cards you basically are shooting yourself in the foot. the games that would need more than 1 4830 would likely also need more than 512mb at that res too.

They're for a new computer i'm building for the lady so i'm not worried

My HD4830 has been great. Overlocks to 700 GPU / 1065 Memory, and always stays pretty cool, only going to 54C when playing Crysis overclocked. I have the Sapphire model (cheapest one) but I think I got a lucky card, as mine seems to overclock better than average.

The cross fire effect is still pretty decent - this is not money wasted. There are several reviews out there, but here is one:

http://www.pcshoptalk.com/foru...ad.php?t=11871&garpg=6

A few examples:

Crysis: High Settings, 1920 X 1200, 4AA
HD4830: 17.1 fps
HD4830X2: 27.9 fps (Note: Gets beaten by the HD4870 1 GB)

Crysis: High Settings, 1600 X 1200, 4AA
HD4830: 18.2 fps
HD4830X2: 33.6 fps (Note: Gets beaten by the HD4870 1GB)

World in Conflict: 1920 X 1200, 4AA
HD4830: 25 fps
HD4830X2: 41 fps !! (Beats the HD4870)

Unreal Tourament 3: 1920 X 1200, no AA
HD4830: 77 fps (still playable, though)
HD4830X2: 133 fps (Beats the HD4870 1 GB)


Note: All tests performed without overclocking. Overclocking is where the HD4830 starts to really shine.

Conclusion: "If you want to have a setup that surpasses in most cases the 4870 1GB, have less noise than the standard 4870 cooling setup and have a lot of room for overclocking, I highly recommend this 4830 Crossfire solution."

I would probably just go for an HD4870 1GB myself, but the HD4830 does get a tangible benefit from XFire.

 

[chizow]

Don't forget there's going to be a 40nm version of this launched in a few weeks (early May) with RV740 expected at sub-$100 as well. The 4830 is an excellent deal for ~$75, but that RV740 may be the ultimate HT card presumably cooler and drawing less power on the smaller process. Potential passive cooling possibilities with good gaming performance, HD acceleration and 8ch PCM over HDMI.

 

[TurtleCrusher]

The only drawback to the RV740 is that it certainly won't overclock like the 4830 because the latter is actually 4850 and 4870's. This revision will be a whole new card.

still runs out of memory in the very games that you need more performance or want higher settings in though at 1920. Far Cry 2, Fallout 3, Crysis, and some others need more than 512mb at 1920x1200. at this point in time its better to have 1gb on a card if crossfire/sli is going to be used.

TWO 4830s for $72? Where?

Well, if you look at the page, I linked to, you can see for Far Cry 2:

Far Cry 2: High Settings, 1920 X 1200, 4AA
HD4830: 25.55 fps
HD4830 X2: 51.02 fps
HD4870 1 GB: 45.22 fps

That's a huge improvement with Crossfire.

They don't have Fallout, and Crysis is pretty much slow with everything. For the price, it's great performance. I don't think your memory limited much at all at 1920 x 1200 if you don't use AA, but even with 4AA you see a huge improvement in Far Cry 2. I don't thik there's much that competes with it at $150.

I wish I had a crossfire motherboard - I probably would buy another one to try out. My single HD4830 can play Oblivion at 1920 x 1200 quite well.

sorry but I will trust sites like bit tech a lot more than that site. even at 1680 a 512mb card starts to falter with 4x AA Far Cry 2. at 1920 with 4x AA a 4870 512mb only has 50% of the minimum framerate of a 4870 1gb. http://www.bit-tech.net/hardwa...on-hd-4870-1gb-toxic/4

Fallout 3 isnt bad with 4x AA but it does drop the minimum to 25 compared to 30 for the 4870 1gb. 5fps usually wouldnt mean much but 25fps would be quite low and very noticeable. going to 8x AA is perfectly playable on the 4870 1gb but the 4870 512mb is not with its single digit minimum framerate. also many people including myself have high texture mods for Fallout 3 so even 4x AA would not be an option with a 512mb card at 1920.

Crysis really wasnt a problem though at least not on their custom benchmark.

That was a good deal buying those on "close-out".

It's 40nm and comes with GDDR5, so it might just overclock more.

Crysis really wasnt a problem though at least not on their custom benchmark.

The difference between the 2 review sites is that BitTech used Ultrahigh quality, while the sight reviewing the HD4830 crossfire used very high quality. So maybe you can't use ultra high quality with 512MB of memory, but it still doesn't mean that money is wasted on a HD4830 crossfire. I don't see any cards at the same price point with the same performance. If you need ultra-high settings, then you need to spend more money (or game at 1680 x 1050).

Here's another review: (yes, I know it Tom's, but it least it shows actual HD4830 crossfire results)

http://www.tomshardware.com/re...crossfire,2098-11.html

The HD4830 crossfire see pretty big gains at 1920 x 1200 with 4X.

Yes, it might be memory limited at high resolutions with some games, but I think the vast majority of them show a significant boost with the second card.

Here is the Far Cry 2 benches from Tom's. The HD4830CF looks to be memory limited at high resolutions, but this is at the highest (ultra) settings. It would be nice to see the settings set to very high - only the HD4870X2 looks playable at that setting.

But doesn't two 512 MB cards add up to 1 GB?

The HD4770 is ~29% faster than HD4830 @ stock clocks.

However, Doesn't the HD4830 come with the same Cooling gear as the HD4850? (Thus allowing good OCs without resorting to an aftermarket cooler)

Fallout 3 isnt bad with 4x AA but it does drop the minimum to 25 compared to 30 for the 4870 1gb. 5fps usually wouldnt mean much but 25fps would be quite low and very noticeable. going to 8x AA is perfectly playable on the 4870 1gb but the 4870 512mb is not with its single digit minimum framerate. also many people including myself have high texture mods for Fallout 3 so even 4x AA would not be an option with a 512mb card at 1920.

Crysis really wasnt a problem though at least not on their custom benchmark.

The difference between the 2 review sites is that BitTech used Ultrahigh quality, while the sight reviewing the HD4830 crossfire used very high quality. So maybe you can't use ultra high quality with 512MB of memory, but it still doesn't mean that money is wasted on a HD4830 crossfire. I don't see any cards at the same price point with the same performance. If you need ultra-high settings, then you need to spend more money (or game at 1680 x 1050).

Here's another review: (yes, I know it Tom's, but it least it shows actual HD4830 crossfire results)

The HD4830 crossfire see pretty big gains at 1920 x 1200 with 4X.

Yes, it might be memory limited at high resolutions with some games, but I think the vast majority of them show a significant boost with the second card.

Here is the Far Cry 2 benches from Tom's. The HD4830CF looks to be memory limited at high resolutions, but this is at the highest (ultra) settings. It would be nice to see the settings set to very high - only the HD4870X2 looks playable at that setting.

How did 4830s in Crossfire beat a single 4870x2? Was the 4870x2 too much for the X38's PCIE slot? (Doesn't X38 have PCI-1.x)

I'll bet that 4870x2 would have done much better in a PCI-E 2.0 slot.

well the whole point of running 2 cards is so you can increase the settings. at 1920x1200 with 2 512mb cards you basically are shooting yourself in the foot. the games that would need more than 1 4830 would likely also need more than 512mb at that res too.

But doesn't two 512 MB cards add up to 1 GB?

no
