Compare The Geforce 7800 Gtx To The 8 Series

Computer hardware is constantly being updated and improved. Every few months, companies like nVidia (a video card designer) release new products. At this rate, it can be difficult to figure out what product is better for your needs. In the case of video cards, like the GeForce 7800 GTX and the newer GeForce 8 series, there are a number of metrics you can use for comparison.

Instructions

1. Compare the GeForce 7800 GTX’s standard features to those of the GeForce 8 series. Assess what impact those will have on your system. For example, the GeForce 7800 GTX is DirectX 9.0 compliant, is capable of SLI configurations and uses Shader Model 3.0. The GeForce 8 series is DirectX 10 compliant, is capable of SLI configurations and uses Shader Model 4.0.

2. Compare the card specifications. Pay particular attention to GPU speed, memory speed, size and type and shader clock speed. The GeForce 7800 GTX GPU is clocked at 430 megahertz. The default version has 256 megabytes of DDR3 RAM clocked at 600 megahertz. The shader capability on this card is handled through vertex and pixel shader units. The GeForce 8 series, on the other hand, has GPU speeds clocked between 450 megahertz and 675 megahertz, depending on the card. They feature 256 to 768 megabytes of DDR3 memory clocked between 400 megahertz and 1080 megahertz, depending on the card. Their shaders are clocked between 900 megahertz and 1500 megahertz, depending on the card.

3. Compare the performance of the GeForce 7800 GTX with performance of cards from the GeForce 8 series. Benchmarks come in a variety of formats, from benchmarking-specific programs such as 3DMark to comparing performance within graphics intensive programs like video games. For example, in a benchmark conducted by the computer hardware reviewers at Tomshardware.com, a 3DMark06 test gave the GeForce 7800 GTX a score of 4605 points. GeForce 8 series cards given the same test achieved scores of 1640 points for lower end cards like the 8400 GS to 12183 points for high-end cards like the GeForce 8800 GTS OC. Higher scores are better in 3DMark06.
