 GeForce 6800 GS 256 MB

 By: Hilbert Hagedoorn | Edited by  | Published: November 7, 2005  

   

The Point of View bagged goodies
 

As you have been able to notice, our review sample today comes from Point of View. The GS will be available in stores starting from today. POV again is doing their name justice and releases a box filled with good stuff. The software bundle is fantastic as you receive two full games - pretty hot ones also which are worth 80 bucks alone.

  • Splinter Cell 3: Chaos Theory
  • Brothers in Arms (Road to Hill 30) Full game
  • Chronicles of Riddick (Full Game)
  • Driver CD with a set of tools
  • S-Video Cable
  • Video Cable + converter
  • HDTV Output cable (RCA 3-way component)
  • DVI to VGA Adaptor
  • 6-pin PSU power connector
  • Manual

There's nothing much to be said here other then it's a very complete bundle and has two very nice games included. The card itself seems to be 100% NVIDIA reference based but we'll show you that and even more in our photo-shoot.

Power Supply Requirements

Now here's where we are going to surprise you a little bit more. Power consumption is really not bad ! Of course the GeForce 6800 GS requires a stable 12-volt power source for best performance and reliability, and most of all that gaming expeience of yours. Many PC power supplies dedicate most of their 12-volt power to the power rail that goes to the CPU, rather than the peripheral connectors. Many power supplies also do not provide ample overload protection to protect system components such as motherboards and graphics cards.

For a SINGLE GeForce 6800 GS graphics card, NVIDIA recommends a 350 watt power supply. For DUAL SLI GeForce 6800 GS graphics configurations, NVIDIA recommends a 420 watt power supply.

So NVIDIA is recommending nothing too dramatic in terms of a power supply unit. Let's test that...

Excuse Me Sir, but Watt Did You Say?


With the ongoing trend in an increased power consumption we will check the statement that NVIDIA made about power consumption in. We simply look at the peak Wattage during a 3DMark05 session to verify those claims. The graphics card consumes roughly 75 Watts at peak during 3D gaming, this is also the reason why we see a 6-pin power connector on the card. Your PCI-Express 16x bus can deliver only 75 Watts to a graphics card. I never understood power requirement decision making as half a year after its release PCI-Express graphics cards were already consuming more power than the slot could provide.

Of course we do what we always do with new graphics' cards, we monitored the overall wattage peak with the help of a wattage meter. Slight side note, you are looking at the overall usage of the PC. The meter is placed between the power connector and the PSU.

In 3DMark the PC shows a maximum peak use of 240-250 Watt. Now you know why 300 Watt Power Supplies are not sufficient anymore these days, you need 350 at the least. We have confirmed NVIDIA's statement.

** Using a Wattage meter is not the most reliable way of measuring power consumption. You basically look at how much power is the power circuit from your house pulling from the PSU. Please look at the results as being an indication and not an exact science.

Is the newborn hot?


Well it's hot in a sexy way, but the temperature remains well within the safety margins.
The standard reference cooling design works really efficiently.

At idle, normal operation, expect roughly 45 Degrees C. At 100% graphics core utilization we measured a maximum 65 Degrees C peak temperature, which is actually becoming the norm. Two years ago I would have freaked out though. Speaking of cooling and thus ventilation, the cooling fan at 100% utilization does not make a lot of noise at all, in fact the HD is producing way more noise then the reference cooler on this NVIDIA graphics card and that's very nice to observe.

The bigger two slot exhaust coolers we see on a lot of cards these days actually do have my preference as single slot coolers tend to dump that heat inside your PC, where as the dual slot coolers are designed to dump that heat outside the PC. As always, make sure your PC is well ventilated.

Noise Levels - dB what ??

Irritating. Yes I'm talking about the noise that PC's these days produce. The only way that will change that is if we all will pay attention to it.

When graphics cards produce a lot of heat usually that heat needs to be transported away from the hot core as fast as possible. Often you'll see massive active fan solutions that can indeed get rid of the heat, yet all the fans these days make the PC a noisy son of a gun. I'm doing a little try out today with noise monitoring, so basically the test we do is extremely subjective. We bough a certified dBA meter and will start measuring how many dBA originate from the PC. Why is this subjective you ask ? Well, there is always noise in the background, from the streets, from the HD, PSU fan etc etc, so this is by a mile or two not a precise measurement. You could only achieve objective measurement in a sound test chamber.

The human hearing system has different sensitivities at different frequencies. This means that the perception of noise is not at all equal at every frequency. Noise with significant measured levels (in dB) at high or low frequencies will not be as annoying as it would be when its energy is concentrated in the middle frequencies. In other words, the measured noise levels in dB will not reflect the actual human perception of the loudness of the noise. That's why we measure the dBa level. A specific circuit is added to the sound level meter to correct its reading in regard to this concept. This reading is the noise level in dBA. The letter A is added to indicate the correction that was made in the measurement.

TYPICAL SOUND LEVELS

Jet takeoff (200 feet)

120 dBA

 

Construction Site

110 dBA

Intolerable

Shout (5 feet)

100 dBA

 

Heavy truck (50 feet)

90 dBA

Very noisy

Urban street

80 dBA

 

Automobile interior

70 dBA

Noisy

Normal conversation (3 feet)

60 dBA

 

Office, classroom

50 dBA

Moderate

Living room

40 dBA

 

Bedroom at night

30 dBA

Quiet

Broadcast studio

20 dBA

 

Rustling leaves

10 dBA

Barely audible

We startup a benchmark, we take the dBA meter, move away 75 CM and then aim the device at the active fan on the graphics card. We measure roughly 50 dBa which is to be considered a moderate noise level coming from the PC. Again, this is a very subjective test.
