GeForce 9800 GT: specifications. NVDIA GeForce 9800 GT

Before the release of the video card 9800 GT, many analysts and journalists believed that the news about the appearance of this graphics adapter is fictional. After the official release, the information cleared up. Many in advance gave the laurels of the championship to this video card as a flagship, but NVIDIA engineers again assigned a new number to the old architectural solutions.

GeForce 9800 GT. Video card specifications

The graphics accelerator is almost a complete copy of the predecessor - the GeForce 8800 GT. And some tests show that the previous generation remains more productive. The novelty is equipped with the same processor - G92, even the technical process has not changed. It remained 65 nm, although many believed that the 9800 GT would use 55 nm. GPU frequencies have not changed.

On the page of the official site, which presents the GeForce 9800 GT, the characteristics are as follows:

• GPU: G92. 112 universal processors, 64 texture units.
• Video memory: GDDR3, its volume is 512 MB.
• Memory bus width: 256 bit.
• The frequency of the GPU: 600 MHz.
• Shader unit frequency: 1500 MHz.
• Memory frequency: 1800 (900) MHz.
• Ports: 2xDVI-I, TV-Out.

The only thing that distinguishes the video card from the 8800 GT is the support for HybridPower technology. It allows you to switch between integrated graphics and a discrete card in an automatic mode, which makes it possible to reduce power consumption and noise level.

Updating this can not be written down as important for the GeForce 9800 GT, it does not change the characteristics , besides, the HybridPower can not work without observing one condition. The motherboard should also support this technology and at the same time carry a built-in graphics core.

Equipment

The video card is shipped in a large enough box, which is decorated with a predominance of blue colors.

Inside it you can find the following:

• The video card itself.
• A set of adapters: DVI-VGA, DVI-HDMI, S-Video-tulip.
• Auxiliary power wire.
• A laser disk with drivers and programs.
• Some revisions include the Civilization IV game.
• User guide.

The texts printed on the package are mainly represented by advertising. However, among the laudatory ones used in the GeForce 9800 GT product, the technical specifications directly indicate that a graphic accelerator based on the 8800 GT is built. Such honesty can be envied.

The presence of a large number of adapters and power wires indicates that NVIDIA takes care of its customers. If you need to connect non-standard equipment or multiple monitors do not have to buy additional components, it will be enough to get them out of the box.

Design

It can be noted that when comparing the GeForce 8800 GT and the GeForce 9800 GT, their characteristics coincide much more than the design. Of course, in general, one board resembles another, but it is impossible to say that they are identical.

Both video cards have the same dimensions, the location of the power connector, the SLI contacts covered by a rubber plug, as well as the position of the GPU and the memory IMS. The chips are manufactured by SAMSUNG, and the sampling time is 1 ns.

The location of the remaining chains is completely different. And the engineers decided not to economize and used the highest quality devices. On the video card you can see solid capacitors. The service life of such products is much greater than that of traditional electrolytic products. Choke coils with ferrite cores also benefit in terms of operating time before the standard ones.

If experts tried to install semiconductors, then the number of ports for connecting output devices is clearly below the top representatives. There are two DVI-I connectors and one TV-Out. But this defect is compensated by all necessary adapters.

Cooling system

Upon closer examination of the NVIDIA GeForce 9800 GT, its characteristics do not seem impressive. However, there is an element on the graphics accelerator that can give odds to many other video cards - it's a radiator. First of all, it should be noted that the installed cooling system is produced by the famous German company Zalman, which is among the leaders of the market.

It is as simple as possible, but it works very quietly and efficiently. A core is applied to the surface of the GPU, on which the thermal paste is applied. Through it, a pair of six-millimeter tubes is missed, their shape is similar to the letter "U". They are made of copper. On top of the tubes are thin aluminum plates.

Logically completes this entire design of a slow-moving screw with a diameter of 8 cm. Its rotation speed is selected automatically depending on the loading level of the graphics core. The only thing that can be attributed to the shortcomings of the cooling system is that it obscures the second PCI EXPRESS slot. If you need to put two video cards on the computer at once, you have to think about replacing the radiator.

Overclocking

NVIDIA GeForce 9800 GT, the characteristics of which are quite modest, can be overclocked with the software included in its delivery. The GamerHUD application can change frequencies while the operating system is running without unnecessary reboots. In addition, the program allows you to perform manipulations with the voltage that is fed to the GPU, but it is not recommended to use this feature, so that the video processor does not fail.

After overclocking, the GeForce 9800 GT continues its stable operation, the frequency characteristics of which have been increased to 700 MHz for the GPU, 1700 MHz for the shader unit and 2000 MHz for the memory. The temperature after overclocking increases slightly, for which it is worth to thank the cooling system.
