GeForce 9500 GT DDR2 vs Radeon HD 6450 (OEM)

Intro

Compare those specifications to the Radeon HD 6450 (OEM), which uses a 40 nm design. AMD has set the core speed at 625 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this specific model. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6450 (OEM)		31 Watts
GeForce 9500 GT DDR2		50 Watts
	Difference: 19 Watts (61%)

Memory Bandwidth

The GeForce 9500 GT DDR2 should in theory be quite a bit faster than the Radeon HD 6450 (OEM) overall. (explain)

GeForce 9500 GT DDR2		16000 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The GeForce 9500 GT DDR2 should be much (more or less 76%) more effective at AF than the Radeon HD 6450 (OEM). (explain)

GeForce 9500 GT DDR2		8800 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 3800 (76%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9500 GT DDR2 is superior to the Radeon HD 6450 (OEM), and very much so. (explain)

GeForce 9500 GT DDR2		4400 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 1900 (76%)

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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock 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 processed per 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. Pixel rate is calculated by multiplying the amount of ROPs 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
