GeForce 8600 GT 512MB DDR2 vs Radeon HD 5450
Intro
The GeForce 8600 GT 512MB DDR2 comes with a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all that to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 memory runs at a frequency of 800 MHz on this card. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
| Radeon HD 5450 |
|
19 Watts |

Memory Bandwidth
Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)
Texel Rate
The GeForce 8600 GT 512MB DDR2 is quite a bit (approximately 66%) better at texture filtering than the Radeon HD 5450. (explain)| GeForce 8600 GT 512MB DDR2 |

8640 Mtexels/sec |
| Radeon HD 5450 |
|
5200 Mtexels/sec |

Pixel Rate
If using high levels of AA is important to you, then the GeForce 8600 GT 512MB DDR2 is a better choice, and very much so. (explain)| GeForce 8600 GT 512MB DDR2 |

4320 Mpixels/sec |
| Radeon HD 5450 |
|
2600 Mpixels/sec |

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 memory bandwidth is, the lower the ability to reach the maximum fill rate.
