GeForce GTX 650 Ti 2GB vs Radeon HD 5830

Intro

Compare those specs to the Radeon HD 5830, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this card. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
Radeon HD 5830		175 Watts
	Difference: 65 Watts (59%)

Memory Bandwidth

The Radeon HD 5830 should theoretically be quite a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)

Radeon HD 5830		128000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 41600 (48%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be much (more or less 33%) faster with regards to AF than the Radeon HD 5830. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 14592 (33%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is superior to the Radeon HD 5830, not by a very large margin though. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 2048 (16%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
