GeForce GT 340 vs Radeon HD 3650

Intro

Compare those specs to the Radeon HD 3650, which comes with a clock speed of 725 MHz and a GDDR4 memory frequency of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
Radeon HD 3650		78 Watts
	Difference: 9 Watts (13%)

Memory Bandwidth

The GeForce GT 340, in theory, should perform quite a bit faster than the Radeon HD 3650 in general. (explain)

GeForce GT 340		54400 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 28800 (113%)

Texel Rate

The GeForce GT 340 should be a lot (about 203%) faster with regards to texture filtering than the Radeon HD 3650. (explain)

GeForce GT 340		17600 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 11800 (203%)

Pixel Rate

The GeForce GT 340 will be much (more or less 52%) more effective at full screen anti-aliasing than the Radeon HD 3650, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GT 340		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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses 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 faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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