AMD Radeon HD 6850 OverClocked to 1 Ghz !!!

[gameranand]

Excellent OCing topgear.

@ all - thanks guys for the comments.

The gpu is cooled down by the stock cooler and the Hyper 212 is taking care of the cpu

Here's the pic of fan control tab

Thanks buddy.

Phenomenal overclocking topgear. Bart chips are really very thermally cool. Btw how much fps are you getting at these clocks?

 

[topgear]

^^ will post game fps difference with stock and Oced clock soon

Excellent OCing topgear.

thanks buddy

Thanks buddy.

you are welcome

@Topgear: can u post the FPS & resolution (Bar Graph) of games u tested on this...
umm..a gaming benchmark

 

[Tenida]

Nice work Topgear I am also planning to overclock my MSI N560TiGTX TFII/OC to 950Mhz-1000MHZ.

 

[topgear]

I've not measured any game's FPS yet - only played them for hours for stability testing but if time permits I'll try to do it

@Topgear

I think the GPU is so cool as its Winter now. Atleast its very cold here. Dont you think?

 

[topgear]

I can't say it's very cold still - when I performed those tests the ambient temp was around ~24c - but from yesterday the climate is getting cooler

 

[comp@ddict]

Good job buddy! 1GHz is awesome. THe feeling you get when you achieve those clocks, amazing.

 

[topgear]

^^ Rightly Said Buddy

>>>>> GAME Benchmarks <<<<< :

Testbed :

AMD Athlon II X4 @ 3.6 Ghz + CM Hyper 212
Transcend DDr2 2x 2GB @ 860 Mhz
HD6850 GPU ( pic on the first post )
GA-MA78GM-US2H motherboard
Corsair GS600 PSU + CM Elite 430
Windows 7 - 64 bit SP1
Sapphire TriXX OC Utility V4.0.2
SamSung B2230
AMD Catalyst 11.10

First a few Words : 1Ghz gpu core clock is a great speed - no doubt about this but the amount of gpu volt need to reach 1 Ghz and the amount of heat does not make it very practical to use for very long time continuous gaming - @ 975 Mhz core clock speed the gpu never went above 70c but with 1 Ghz the gpu easily reached 72c

I want to run the gpu under 70c as in the summer the temp will increase and the fps difference between 975 Mhz and 1 Ghz is merely a half fps - so the most of the game benchmarks are going to use 975/1150 as the highest OCed speed - I did include two 1 Ghz game benchmarks and a 3DMark 11 Xtreme score just to show how much difference does it makes :

1000/1150 :

Stock : 820/1100 :

Now Games :

All games done @ 1920*1080 i HD resolution to see how capable this gpu is in HD gaming and how far the OC improves it's performance in HD gaming - sometime I used 4x MSAA instead of 8x Msaa to compare the scores with some benches of Tom's hardware

Lost Planet 2 : Highest Quality, 4x MSAA :

Crysis 2 - Ultra - Every Other Settings Turned to Max possible

*i39.tinypic.com/1zlsnic.png

DiRT 3 - Ultra - 8x MSAA

*i43.tinypic.com/2hgbebt.png

F1 - 2010 - Ultra - 4x MSAA

*i40.tinypic.com/10yjitj.png

AVP 2010 :

1920 x 1080/Very High/High/16/SSAO On/TS On/AS On/4X

*i44.tinypic.com/24px954.png

Metro 2033 :

1920 x 1080; DirectX: DirectX 11; Quality: Very High; Antialiasing: MSAA 4X; Texture filtering: AF 16X; Advanced PhysX: Disabled; Tesselation: Enabled; DOF: Disabled

[Skud]

Nice scores, tg. Game on.

 

[S_V]

Very Good scores mate... Enjoy Gaming..

Damn that Metro 2033 .....it's simply not playable at that framerate... Also very good game..

 

[Skud]

Turning off AA will help.

 

[topgear]

with Medium settings , 4x MSAA, 16x AF, No PhysX, No DoF Metro can runs @ 44 fps which is playable enough

 

[Zangetsu]

good testing topgear....

Metro 2033 is one heavy resource demanding game....

 

[d6bmg]

Another very goos set of benchmarks, topgear.

 

[topgear]

A little performance analysis

Tom's guys have used :

Core i5 2500k Oced at 4.5 Ghz - A much more powerful cpu but does it really matters in High resolutions and Maxed out settings ??

SAPPHIRE TOXIC HD 6870 @ 970/1150

HIS HD6870 IceQ X Turbo X is clocked at 975/1150 -

HiS has a stock clocked IceQ X gfx card but looking at the performance and FPS it's clear Tom's guys have used the Highly Oced Turbo version and that's why it's neck to neck with Sapphire's HD6870 Toxic Ed.

I've used the same game settings for benchmarks as Tom's guys used in their test and at HD resolution in Metro 2033 I got 26.33 and in AVP I got 33.7 Fps which is neck to neck with Similarly Clocked HD6870s in Metro 2033 and AVP and Check out the load temps :

So what's your take on this

 

[Jaskanwar Singh]

Nice analysis TP. Custom cooled 6850 are truly bang for buck.

^^ thanks .. will try to find how far it goes with sock volts and some credit goes to winter season
