Radeon 7750 vs 6850

[giliara]

I am gonna make a build using a low profile card and I was wondering would a low profile 6850 be a better choice than the Sapphire low profile 7750 for $55 more dollars?

 

[Sakkura]

The 6850 is significantly faster. Up to you whether $55 is worth it.

 

[emad_ramlawi]

hmmm the 6850 will give you better performance comparable to the hd 7770 and maybe a tad a bit better.


However you said low profile thus i assume you are building a small machine, like Mini-ITX

in those circumstances, small + efficient are both clear winners, cause of the restricted cooling inside those cases, thus IMO an 7750 will perform much better, and its cheaper, and in the future you can upgrade to the coming soon HD 8000 series, which according to leaks, will have a very powerful successor of the 7750

 

[geofelt]

I think not; they are close to the same performance tier.
In addition, the 7750 needs a lesser power supply.

I found this website, IDK how good the coolers are on the 6850 http://afoxbuy1.jimdo.com/products/

You may also want to consider Geforce 630.
Looking on Newegg its the best low profile Nvidia card. It won't have the same performance as the 7750, but it will perform pretty decent still, its low on power, and its $55 cheaper. You should only consider it if you want to save money and power at the cost of performance, but just a 3rd option.

 

[emad_ramlawi]

the 6850 uses 6pin power connector and PCI-e power thus max theoretical load is = 150W, real life usage = 120 W

the 7750 uses only PCI-e power thus max theoretical load is = 75W, real life usage = 55W

Also 7750 gets an extra +1 cause all the current driver optimization done at AMD benefit the 7000 series and focuses on those.

the 6850 is good performer i dont want to confuse you or throw you off, however it consumer power and produces more heat, in my opinion going with it will not only cost you 50 USD dollars, cause you need a good PSU with 6-pin connector, however going with 7750 will reduce the need for gaming PSU, and you can end up with a good certified 400W PSU or 350W.

So it all depends on you and what CPU you will utilize for example the i5-2500 Sandy uses 120W on full load and averages on 90-100.

So it all adds up, max sure you calculate your build wattage usage.

And its known fact that the 7750 default cooler is near silent.

My opinion instead of paying too much to get the 6850 working + , for now grab the 7750 cause its very cheap, and save the money in your pocket, for something else, or wait for the next cycle to upgrade.

No. Hell no. It's vastly inferior to the 7750, let alone the 6850. It's a rebadged GT 440.

 

[IInuyasha74]

Sorry, made a slight mistake in post above. It is closer to $100 cheaper.
Again it isn't quite as good as a 7750 but still will perform well. It has 384 CUDA cores like the Geforce 640 and 650.

It's a Fermi card, not Kepler. It offers LESS performance per watt than the 6850, let alone the 7750.

Okay, so for the processor should I go with an FX-6300 which combos with a motherboard (Micro-Atx) at Microcenter for $125, or should I get an A10-6800K to crossfire with a 7750 or would that cause too much heat.

 

[emad_ramlawi]

FX-6300 + 7750 = sounds to me a perfect combination for good price/performance and also efficiency

Your CPU + External GPU will Load at 200W and on average usage will consume 150W so trust me do not pay premuim for the PSU, grab a good certified 400W or 450W and that will be more than enough

 

[Sakkura]

Yeah the FX-6300 and 7750 would be better. It's unfortunate that Microcenter don't have good Core i3 bundles, because a Core i3 would be good for a small form factor system. But with a 7750, a FX-6300 won't be a problem.

Thanks I can get this build under $400 for my cousin (He's a light gamer).

Its both. There are two Geforce 630 cards. There is a rebadged 630 with 96 CUDA cores and a 128-bit interface which costs about $100 on newegg. Then there is a Kelpler version with 364 CUDA cores anda 64-bit interface. It is worse than the 7750, but it can still play games and it is vastly cheaper.

For confirmation on what I am saying, please check the Nvidia site specs.

If this build is for gaming, spend about twice your budget on the graphics card than you do on the cpu. Since you will be using a discrete graphics card, I would bypass the A series cpu's.

You should also note that you cannot crossfire a 7750 with an APU. At this moment with the current APU's it just isn't possible. It can only crossfire with a specific 6000 series card, I forget which one, but it doesn't matter really cause it doesn't give better performance than the card itself gives. The graphics in the APU are just too slow to make a difference. So Sakkura is right the FX-6300 is a better choice.

Hmm, thought that was OEM-only. But it seems you're right. However, the cheapest one is $75 at Newegg (the Fermi GT 630 is close to $60), and that's more than the 7750 costs...

Might be how I am searching it up, not sure. The cheapest 630 I found is this one.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814500305
It says stream processors, but thats just a mistake in the listing. It means CUDA and it has the 64-bit interface to make sure, so its a Kepler design. It's only $64 after shipping costs.

This is the cheapest 7750 I am seeing.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814103231
It is $124 after shipping. Almost twice the cost.

At those prices's I think the 630 would give better performance/dollar. It might be because I am specifically selecting ones which are marked to come with a low profile bracket. If you can find a 7750 for $75 though that would be a much better deal and you should take it.

 

[IInuyasha74]

Sorry for the double post.
I looked around more on Newegg and found there is one 7750 closer to $90, maybe one is even cheaper. Their listings are all messed up though. I can only find the 630 I linked above by selecting low-profile in the side options and no other way, and it even has mistakes on its page.

Also the cheaper 7750 I found is low profile and doesn't show up in the low profile group. So they are having mistakes on their page. Make sure you look around carefully.
