GeForce GT 315 vs Radeon HD 3650

Intro

Compare all that to the Radeon HD 3650, which features GPU clock speed of 725 MHz, and 1024 MB of GDDR4 RAM set to run at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315		52 Watts
Radeon HD 3650		78 Watts
	Difference: 26 Watts (50%)

Memory Bandwidth

Theoretically, the Radeon HD 3650 should perform a small bit faster than the GeForce GT 315 overall. (explain)

Radeon HD 3650		25600 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 320 (1%)

Texel Rate

The GeForce GT 315 should be quite a bit (about 72%) better at anisotropic filtering than the Radeon HD 3650. (explain)

GeForce GT 315		10000 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 4200 (72%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 315 is superior to the Radeon HD 3650, by a large margin. (explain)

GeForce GT 315		5000 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 2100 (72%)

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 data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied per second. This is worked out by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
