Sapphire HD 5770 vapor-x or Sapphire HD 5850 Game edition

micun · Nov 10, 2013

Hi.I need little help. I have choice to buy used Sapphire HD 5770 vapor-x for 60$ and
Sapphire HD 5850 Game edition for 70$

Currently I have Sapphire HD 4830 512 mb.I have psu enermax 460w 12v 33 amp. Would It be enough for hd 5850. I read a lot of reviews and I see that hd 5850 req 150w.

Thank you

150(12.5 amps) sounds about right at full load for that card.

It takes more power than the 5770(I ran one of those on a 300 watt power supply with 22 amps

. The system was a real lightweight), but also should be faster.

the 5850 will be better but i doubght that your psu could handle it if you could get a better psu go for it there are some good one on the net .see this http://www.gpureview.com/show_cards.php?card1=615&card2=614

nukemaster :

hi. I am not sure if I understood it right. Would my psu be enough for
HD 5850? I will give you links to see some tests for this cards.
According to tests:
HD 4830 130 W ( which I currently have in my pc)
HD 5770 vapor-x 118 W
HD 5850 150 W

If this tests are correct? If my psu can handle 130 W maybe it could handle 20 wats more for HD 5850? what do you think

What else is in the system.

Many users think systems take more power or that they take MAX power all the time.

If a system is rather light in hardware, it leaves extra power for the video card. So a ITX system with a lower powered cpu and a single 3.5 inch drive will take less power than a eatx system with a highly overclocked cpu and 4-8 hard drives.

As an example. My mITX system with an i5 750(under volted) and 1 3.5inch[WDC red 3tb] drive and 1 2.5(WDC Blue 1tb) + ssd(128gigabyte M4) takes under 150 watts under most gaming situations with a GTX 650 ti installed in it(Highest I have got was about 180 with Prime95 + Just Cause 2).

On the other end, My I7 920(slightly undervolted, but also overclocked with 3 x7200rpm HDDs with a 5870 took about 150 watts at idle and could get upto about 350 when under heavy load.

My current I7 2600K with 2 ssd's with 1 5900rpm 3.5 inch drive with same 5870 was under 90 watts idle.

I have not taken numbers with the GTX 670, but my guess is things are even better.

You do NOT want to push a power supply near the max either.

nukemaster :

ok. thank you for your answer. I have Core 2 duo e8400 overclocked to 3.6 GHZ with freezer 7 pro rev 2. I have 2 hard disks 500 and 750gb, dvd-rw and dvd-r, and 2 coolers od 120mm.that is it. what do you think? Thank you

I think you should be okay with the HD 5850 since the Radeon HD 4xxx generation consumed more power than the HD 5xxx generation. But I need to double check later when I'm on my PC.

Your PSU should be more than enough, at a theoretical peak load (as in worst case scenario: absolutely 100% tdp on everything which is barely achievable) you should only be consuming around 400 watts given your hardware.

If you'd like to verify, check here and just enter your system details, from past experience this site is highly accurate:

Thank you so much for your answers. Then I will go for HD 5850. Would my e8400 OC 3.6 GHZ be enough for 100% potential with this card? or It would bottleneck little? Thank you

micun :

Depends on the game you're playing, some are CPU heavy whilst others favour the GPU. It is likely that some CPU bound games will be bottlenecked by the E8400, your best bet is to monitor GPU usage in afterburner and make sure you're typically getting >90% usage.

Did you checked ? What is your version of HD 5850 and what are temps?
This one is blower. Is it true that blower are noiser and hotter?

I was wrong with my "guess-timate", the Radeon HD 5850 actually consumes more power than the Radon HD 4830 (about 17w or 1.5 amps) at 108w peak. Maximum power consumption occurs only when running the FurMark benchmark.

http://www.techpowerup.com/reviews/HIS/HD_5850/28.html

Having said that, I don't think you should have much of an issue running a Radeon HD 5850 with your PSU. I believe I have a Sapphire Radeon HD 5850 which runs at stock speed similar to the one you linked.

I prefer graphic cards like that which exhausts hot air out the back of the card rather than dumping it directly into the case which increases overall internal temps which can cause other fans to spin faster.

Thank you all for help.

Blowers aren't necessarily hotter, they're just ALOT louder to achieve the same cooling performance of a non-blower. They have just as much cooling capacity though.

Eg. A blower can keep your card at 60 degrees celcius but might have to use 50% fan speed and be very loud whereas a non-blower would be able to do the same at say 60% but be far quieter.

If noise and temperatures are a problem to you a blower might not be the solution:

nukemaster · Nov 11, 2013

I recommend the blower as the above user recommends if your case has less optimal performance. I know my SFF would have a hell of a time getting rid of extra heat.

I did test with a GTX 650 ti and it was OK, but high powered cards do push lots of heat.

Do not be worried even if the 5850 gets into the 70-80 range. They can take it.

I just read some reviews about hd 5850 dx 11 performance. is it true that hd 6850 is better because improved tesselation ( whatever it is) ? Did you try Call of Duty Ghosts and Crysis 3? Is performance good? Thank you

jaguarskx · Nov 14, 2013

Generally, the HD 6850 is better than the HD 5850 in DX11 games from what I can remember. That's simply because the DX11 hardware has improved. However, the HD 5850 does better in DX9 games and I believe possibly in DX10 in DX11 games as well.

For example, Skyrim is a DX9 game and will likely perform better with the HD 5850. But Battlefield 4 is a DX11 game and you will likely get better performance with the HD 6850.

jaguarskx · Nov 14, 2013

I will also add that AMD has released a game development tool called Mantle. Basically it is suppose to improve performance of games that were developed with Mantle (like Battlefield 4). However, you need to have a Radeon HD 7xxx (or newer) card to make use of it. Intel and nVidia graphic cores do not benefit from Mantle because it requires hardware that AMD have designed into their HD 7xxx cards as well as the current Radeon R9/R7 series.

micun · Nov 14, 2013

Thank you for your answer. I can not wait for this Sapphire HD 5850 to arriive. So all in all will it be good enough for games that req DX 11? I right now play Battlefield 4 on my HD 4830 at low 1280*1024 ( That is maximum res of my monitor, I plan to buy bigger) and I get FPS 25-30. I imagine it will be a lot better with HD 5850? I do not need to play on ULTRA. Just HIGH.
