Asus Radeon HD 5850 1GB GDDR5 Graphics Card

Testbed, Temperatures & Overclocking

Testbed
 
AMD Phenom II X4 965 Black Edition @ 3.94GHz
4GB Corsair XMS3 DDR3 @ 1333MHz
Gigabyte MA770T UD3P Motherboard F4 BIOS
Asus Radeon HD 5850 1GB GDDR5 Graphics Card 
Samsung Spinpoint F1 320GB SATA II HDD
LG 22x DVD+/-RW SATA
Arctic Freezer 64 Pro CPU Cooler
Windows Vista Home Premium
 
Temperatures
 
We used Furmark's stability test to record the Asus Radeon HD 5850's load temperatures. After 30 minutes of idle monitoring from a cold boot, the test was loaded and was ran until temperatures and fan speeds had appeared to have stabilised. The results were as follows.
 
 
Like all of our previous Radeon HD 5800 graphics cards, the load temperatures maxed out at 80*c with a fan duty speed of 35%. The noise levels even on our open test bed was tolerable. While the graphics card was obviously audible under load, the noise was the sound of airflow rather than motor noise. There's minimal buzzing and more importantly no whine. As said in previous reviews, this is to be expected given that Asus have not made any changes to the reference heatsink for their 5800 series graphcis cards.
 
 
Asus SmartDoctor & Overclocking
 
 
As you may or may not know, ATi's own Overdrive utility in the Catalyst Control Center offers overclocking support for the Radeon HD 5850. Aside an Auto Tune feature, it also offers manual overclocking support. The only real nuisance however is that it's maximum boundaries stand at a paltry 775MHz on the core and 1125MHz (4500MHz GDDR5 effective) on the memory. Understandable I suppose given that ATi need to keep the graphics card as far away from the current HD 5870 flagship as possible given the £100 price difference.
 
This is where Asus' own overclocking application comes into play. Not only does it offer frequency increases to insane heights, it is also meant to offer Voltage Increase support. The keyword however is meant as no matter what we did, we could not get the application to select a voltage higher than the HD 5850's default 1.088V.
 
We found our maximum stable frequency at around that of the Radeon HD 5870's defaults, at 854MHz core and 1240MHz (4960MHz effective) memory. A 129MHz / 240MHz increase shouldn't be frowned upon of course. The graphics card was returned to it's default clockspeeds for the testing that was to follow.

Awesome card, it's a damn shame that they've seen fit to hype the prices. All said and done, hitting the market at around £200 and slipping to £175-ish would have made it mouth-watering for some.

I think it's gotten to the stage that lack of availabilty needs to be in the bad section 'at the time of writing', in so much that when ASUS see the review/feedback they can perhaps take more notice of what the enthusiasts are saying also. Having a choice, but not being able to find it, is a really bad thing.

Tool looks good, not so good with the voltage thing lacking, perhaps an upd8 will come along to sort that out.

Typical of ASUS gfxcards I've experienced of late, well build, look pretty good and is probably sounds strange, but I bet it felt good when u took it out of the anti static.

Good stuff, bad timing maybe.Quote

The price gouging is unacceptable IMO. The lack of availability for these new products (and SSD's) is getting to be a bit of a joke.

It is a nice mid range card though, it performs well on the test bed. It will be interesting to see how these DX11 cards handle DX11 titles...Quote

I totally agree it's like us saying we are now going to work 3 days a week but to cover for the lack of wages we will increase our wages by 40% to cover for the loss we will take.

These Basterds decide to make less and charge more to keep their income the same as making more for less. We are in recession all workers get litlle or no wage increase and companies like this will reduce staff to make less then charge more to make the price right so the Basterds at the top make more money for employing less and working less as well.

Simple answer no one buy a single item until the price drops, we can easily force them to drop the price, it would not harm us to not buy the card for a month yet it would cripple their company if we don't.Quote

Am i the only one that noticed the Crysis Warhead graph was actually the Call of Duty stats?

Maybe it's because i always jump to those FPS results

If people weren't out trying to buy them the price wouldn't be so high, ye olde supply and demand.

Blame the ****s that want to pay over the odds for such kit, the buisness' are just taking advantage of it... unfortunately that's what all business' do!Quote
