GeForce 9800 GTX+ vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific model. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

Radeon HD 6750 1GB		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce 9800 GTX+ should be much (more or less 81%) more effective at AF than the Radeon HD 6750 1GB. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 21132 (81%)

Pixel Rate

The GeForce 9800 GTX+ should be a bit (about 2%) better at full screen anti-aliasing than the Radeon HD 6750 1GB, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 208 (2%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
