My Saphhire 5850: A review


INTRODUCTION


This is a review of my own Sapphire 5850, which i know that is being presented a little late, but since i got my new monitor, i was made available of new resolutions (to me, at least) like 1920x1080, so i wanted to test the potential of my card at these resolutions.
BUT, KEEP IN MIND, DO NOT JUDGE THIS CARD BASED ON THIS REVIEW: WHY?
I'll tell you why
My processor is old, old enough that it used to bottleneck my old 4850, let alone 5850, so in many cases there is no huge improvement, in some, none at all
but as this is my personal review, i am posting results as i got them, nothing biased.

With many professional benchmarks out there over many sites dedicated to the purpose of reviewing hardware only, i ask you to consult them if you are going to purchase this card, cause they will tell you how good this performs when coupled with a good processor.

Enough talk, lets get started

TEST SETUP



AMD Athlon64x2 6000+ @ 3.01 GHz
Gigabyte MA61-PME-S2
2GB DDR2 667MHz
Corsair VX450
Sapphire 5850 @ stock clocks [725/1000]
Sapphire 5850 Overclocked [925/1150]

ATI Catalyst 10.12


TESTING

Heaven Benchmark 2.1

Furmark

3d Mark vantage

3d Mark 11

Far Cry 2

GTA 4

Crysis


Overclocking

This part usually comes in the end, but i will be comparing the results at stock as well as overclocked card, so i am introducing it here

This Sapphire has been flashed to an ASUS BIOS, to enable voltage tweaking, for which i used ASUS SmartDoctor, and then i overclocked it the normal way

Here is a pic showing card at 925/1150, under 100% load with temperature at 73 and Fan at auto








3D Mark Vantage: Results



5850 : 725/1000 [stock]






5850: 925/1150









5850 : 725/1000 [stock]





5850 : 925/1150








FURMARK :Results



5850: 725/1000 [stock]

Score -- 6398





5850: 925/1150

Score -- 7955







Heaven Benchmark Results

Default settings


5850: 725/1000 [stock]

Score - 679





5850: 925/1150

Score - 819







Far Cry 2

Settings: 1920x1080,ultra high,8x AA

5850: 725/1000 [stock]





5850: 925/1150







The reason in my belief for no improvement is because of the bottleneck by my processor





Crysis

Settings: 1920x1080,High,0xAA

Look at the last line of the image for results


5850: 725/1000 [stock]





5850: 925/1150






Again, my assumption is that processor is a (huge) bottleneck





GTA 4:

Settings:
Res =1920x1080
View Distance = 48
Detail Distance = 100

Other settings = High

5850: 725/100 [stock]





5850: 925/1150






This game, as we all know, is very CPU dependent, but it was showing some very good OC results



So, these are the applications i have reviewed, and i have arrived at these conclusions
This card overclocks like mad, as most of us know by now
i tried 1000/1250, but artifacting was uncontrollable
so i had to revert back to these clocks.

Till now, i am happy with my card, provided i have not seen its true colours till now,which wont happen till the time i dont buy a new processor

There are many games without in built benchmarks, but i use fraps to bench them.

Well, this was all, hope you find it useful.


These benchmarks have been performed on my new monitor, and i can tell you after using 15 inch CRT for 11 yrs, i am blown away at the difference

Re: My Saphhire 5850: A review

Thanks for the review mate. Yeah, as you've concluded, the CPU and RAM appears to be the bottleneck in many of the benchmarks. An AMD Phenom CPU + 2 more GBs of RAM should pump the scores a bit more.

73 at 100% load is not bad; for how long the load was there? And did you try hooking up you HDTV with it (assuming the card got an HDMI port).

Re: My Saphhire 5850: A review

my monitor does not have hdmi port, just vga and dvi

and yes, card was at load for 4 min here in the furmark pic i have shown
but i did it for 10-15 min, it was never above 75
it wasnt the highest clock you see, i was able to reach 1000/1200 but i had to keep the fan at 90% to keep it cool
