GeForce GT 315 vs Radeon HD 6450 (OEM)

Intro

Compare all of that to the Radeon HD 6450 (OEM), which features clock speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.

Theoretically speaking, the GeForce GT 315 will be 98% faster than the Radeon HD 6450 (OEM) in general, due to its greater bandwidth. (explain)

GeForce GT 315		25280 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 12480 (98%)

Texel Rate

The GeForce GT 315 is a lot (approximately 100%) more effective at texture filtering than the Radeon HD 6450 (OEM). (explain)

GeForce GT 315		10000 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 5000 (100%)

Pixel Rate

The GeForce GT 315 is a lot (about 100%) better at FSAA than the Radeon HD 6450 (OEM), and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 315		5000 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 2500 (100%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
