GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3650

Intro

Compare those specs to the Radeon HD 3650, which uses a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR4 RAM is set to run at a speed of 800 MHz on this particular card. It features 120(24x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
Radeon HD 3650		78 Watts
	Difference: 28 Watts (56%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce 9500 GT 1GB GDDR3 will be quite a bit (more or less 52%) more effective at anisotropic filtering than the Radeon HD 3650. (explain)

GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 3000 (52%)

Pixel Rate

The GeForce 9500 GT 1GB GDDR3 is much (approximately 52%) faster with regards to AA than the Radeon HD 3650, and able to handle higher screen resolutions more effectively. (explain)

GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 1500 (52%)

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 max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 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 number of texture map elements (texels) that can be processed in one 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 this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
