New video cards, such as NVIDIA GeForce 7800 GT, are supposed for the gaming sector of the industry. The line GT has all the functions of the top card 7800 GTX, but it has a more attractive price.
The 7800 GT is another variation of the processor NVIDIA G70 with the support of DirectX 9.0, OpenGL 2.0 and Pixel Shader 3.0. There are twenty pixel conveyors and seven blocks of the top programs. The GT version is provided with a 256 MB DDR3 memory and a 256 bit interface.
There are some implementations of this video card by different vendors. Let us take a look at the video cards eVGA 7800 GT and XFX 7800 GT. The layouts of both cards are close to the reference design by NVIDIA, but XFX and eVGA decided to increase the clock rates. It was a good step to make their video cards more attractive.
The video card eVGA 7800 has a clock rate of the graphical kernel 425 MHz. NVIDIA provides 400 MHz in their specification. The video card is developed for a new advanced interface, PCI-Express. The eVGA PCI solution allows the support of increased technical parameters. The card is supplied with a 256 MB GDDR3 memory and a 256 bit interface, which works with a clock 1.07 HHZ (DDR).
The same way as other NVIDIA 7800 video cards the eVGA model takes one slot. It offers a significant cooling for the graphical processor and memory modules. A cooler has a lower noise level even in a 3D mode.
The eVGA video card has modern 3D functions, such as a bilinear, three-linear and anisotropies texture filtering. It has a DVI 2x output, a S-Video output and a TV-output for HDTV (Y, Pb, Pr). There are also audio, S-Video and composite video inputs.
eVGA provides a disk with the software Cyberlink PowerDirector 2.55 ME Pro and the game BattleField 2 with their video card. The CyberLink application includes the software for a DVD recording and the DVD PowerDirector 2.55 ME Pro. The company plans to issue the video cards with the game Call of Duty 2 after the game's release.
The video card is presented with a fresh driver for the moment of release. Consequently, you can download a driver from the official NVIDIA web-site. The company NVIDIA grants the WHQL-certified drivers of version 80.
There are many cables, provided with the eVGA GeForce video cards, including an input-output cable for the connection with an external block and an S-Video 1x cable, which is a perfect bonus for the clients. There is also an opportunity to obtain an additional power supply cable with the video card. Thus, the owners of old power units can connect two Molex plugs and get a six contacts power plug.
A component video cable with an external block is another bonus from eVGA. You can attach the block with stickers to the side of chassis. The block contains cutoff points YprPb for connecting HDTV displays to the TV output of the card. Additionally, there is one output S-Video and also a cable S-Video. You can connect many devices to your PC without any adapters and a video-camera or other hardware to your PC via the S-Video cutoff points.
Therefore, the eVGA PCI-E GeForce 7800 GT is a product, worth of your attention. This is a successful implementation of NVIDIA reference and it has some additional pleasant surprises, which can make this product easier to use.
