ATI 4850 vs AMD 7750

[Mesonto]

Okay so I have been researching this one for a month now. But I cannot find out which is actually faster or quieter. About 3 years ago... maybe more, I bought a Powercolor 4850 and it has served me extremely well, but it does need the extra power connector and it also makes a constant buzzing noise because of the fan. Now Powercolor have released their 7750. Will this card be faster and quieter and I assume more energy efficient? I know it sips a lot less power.


The reason I am talking Powercolor here is that both boards fit into a true single slot in my Shuttle case.


Any help would be appreciated.

7750 vs 4870 bench
anandtech review

Looking at the bench, I was expecting a bigger gap between the 4870 and 7750. Maybe drivers just aren't fully optimized yet.

From my experience with a 4850 and 5770, I can say the performance difference is there, but not terribly noticeable. 7750 is close to a 5770, which is about 20% over a 4850.

However, the difference in power consumption is going to be huge. Like enormous. 4xxx series was pretty hungry at idle, and the 7750 uses way less at both idle and load.

4850 and 4770 are nearly equal but 4850 is slightly faster

5770 is nearly equal to a 4870

4850 will be like 10-20% faster than a 4750 across the board,

4870 to 4850 is like 7970 to 7950

So going from a 4850 to 5770 is like going from a highly Oced 580 to 7970

Only buy the 7750 for purposes of cutting back on noise/heat/power. It will not be noticeably faster than the 4850 - on the order of 15%, but potentially much more if you have the 512MB version and you're playing a relatively new game.

If you want to upgrade go for at least 7770 minimum or 6850 or 5830 or gtx 460

+1

and depending on your budget, i would personally never buy those half hacked sub video cards under their main serie

i.e. 5770 instead of 5800 or 7770 instead of 7900 etc

Cannot do this because I only have a single slot available. Therefore it is the 7750 or I am keeping my 4850.

I'm sure all these comparisons made sense to you when you wrote them, but when someone else is reading this, it seems about as straightforward as this girl giving directions is:

I don't think a 4850 would be compatible with a 7750.

 

[Ancalagon44]

Wow I expected a bigger improvement after 3 generations. I mean the 7750 is mid range, but still, its many years newer.

 

[wahdangun]

yup, get that HD 7750 if you want more powerful, power efficient and quitter card.

 

[mosox]

Look for the PowerColor AX6850 maybe you can find it.

 

[aaksheytalwar]

7750 isn't mid range, it is entrl level. 4850 was mid end of its time, 5770 was mid range for its time, so a nearly high end GPU 3 generations back will still compete with something entry level today, that has always been the case.

mid range is 7850 and 7870.

Have been looking for this one but I cannot find it. I realize it is supposed to be a single slot as well.

On a different note: I really lament the fact that video cards have gone dual slot!!! And at this point it is really starting to piss me off.

Do you need single slot because of the back bracket or because you literally don't have enough space in the case for a double-wide cooler? I ask because there's an HD5770 card for $70AR/FS that has a single-slot bracket but a dual-slot cooler: http://www.newegg.com/Product/Produc...82E16814161401

That would be faster and much cheaper than the 7750.

I have an old Shuttle case, and actually put a card in with a double-wide cooler - just needed to make sure the bracket itself was single-slot, as the case was only designed for that. Often there's extra space in the case for a larger fan.

If you truly need single-slot, there's always this $120 HD6770: http://www.newegg.com/Product/Produc...82E16814150574

It's faster than the 7750 (and exactly the same as an HD5770, but more expensive): http://www.anandtech.com/bench/Product/538?vs=535

Yes I actually need a single slot. One slot for card and cooler.

Your HD6770 is interesting: It trades blows in speed comaprisons, but uses more energy but then is also quieter! It almost seems like a either/or scenerio. The only caveat to eh 6770 is that I would also have to buy convertors for my DVI only monitor and a new cable for the HDMI one.

In that case, definitely just go for the 7750. It uses very little power, doesn't require extra power cables, and it has the connectors you need. It's just not particularly powerful for the price. Usually, single-slot coolers run much louder than double-slot coolers on the same card, but this video review of the card that says noise/heat is fine: http://www.youtube.com/watch?v=VgrxTnskjY8

No, the x400 to x500 cards are entry level. The x600 is budget, the x700 is mid range, the x800 and x900 are high end. Just because all gamers tend to buy x800 or x900 cards, doesnt make them mid range.

 

[aaksheytalwar]

Wrong. That was when the naming was introduced

With the 7 series
7100-7600 doesn't exist for the desktop segment
7700 entry level
7800 mid range
7950 performance mainstream
7970 high end

6000 series

6990 enthusiast
6900 high end
6800 mid range
6700 lower mid range
6600 low end
6500 entry level

5000 series
5900 enthusiast
5850 and above high end
5700 mid range
5600 entry level


What you stated keeps changing and for the 6000 series only 6700 and 6800 were mid range but for 7000 series only 7800 series is mid range

7750 replaces the 6750 which is a previous gen low-mid card making 7750 entry level today

And doesn't even haven anything less powerful than this

 

[Concillian]

No, the x400 to x500 cards are entry level. The x600 is budget, the x700 is mid range, the x800 and x900 are high end. Just because all gamers tend to buy x800 or x900 cards, doesnt make them mid range.

There are no x400, 500 or 600 this generation because Trinity integrated graphics are expected to largely make those cards obsolete. 7750 is low end discrete.

And the single slot / dual slot thing happened when they ran out of headroom on power. I had a 7800 GT that was a $200ish card back in the day... That mid range card used less power than today's low end... Previous gen improvements came from process improvements AND jacking up the power, but they've pretty much gotten to the point where each market segment has a given power usage and that's what they get to work with. Consider that the 7750, the lowest end GPU in AMDs 7 series lineup has a power budget roughly equivalent to a 3770k, the highest end Ivy Bridge CPU in Intel's upcoming lineup... The lowest end GPU is designed for the same power envelope as the highest end IB CPU.

Single slot coolers aren't seen much anymore, because GPUs are expected to perform better than a single slot cooler is capable of comfortably cooling. Back when I was using that pretty high end 7800GT, I was also using a 1280x1024 monitor along with the bulk of the market. Now the main res is using ~60% more pixels (1080p). If everyone was happy with 1280x1024, then many would also be cool using 7750s for mid to high end gaming too.

I see your point. I dont know, I guess I have a problem with something that costs over $100 being called entry level. In days gone by, that would be a solidly midrange price.

Its probably true that AMD's APUs have made the 7100 to 7600 series obsolete as far as gamers go, its just that entry level brings to mind cards that could barely run an OpenGL test. A 7750 is a pretty capable card, even in today's games.

If you play at 1920 1080 then anything less than a 7850 isn't good enough for the top 30% intensive games. For 12 by 7 a 7750 will cut it at high settings I guess, not max though

Have you even read the OP? You keep recommending the 7850 in post after post to people looking to spend $100. Furthermore, the card isn't even on the market yet.

 

[aaksheytalwar]

Don't get a 7750. Get a 7770 and overclock it
