GeForce GTX 285 1GB vs Radeon HD 7870

Intro

The GeForce GTX 285 1GB uses a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 RAM runs at a speed of 1242 MHz on this card. It features 240 SPUs as well as 80 TAUs and 32 ROPs.

Compare all that to the Radeon HD 7870, which features a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 memory running at 1200 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7870 175 Watts
GeForce GTX 285 1GB 204 Watts
Difference: 29 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB will be 4% faster than the Radeon HD 7870 in general, due to its greater data rate. (explain)

GeForce GTX 285 1GB 158976 MB/sec
Radeon HD 7870 153600 MB/sec
Difference: 5376 (4%)

Texel Rate

The Radeon HD 7870 will be much (approximately 54%) more effective at anisotropic filtering than the GeForce GTX 285 1GB. (explain)

Radeon HD 7870 80000 Mtexels/sec
GeForce GTX 285 1GB 51840 Mtexels/sec
Difference: 28160 (54%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 7870 is superior to the GeForce GTX 285 1GB, and very much so. (explain)

Radeon HD 7870 32000 Mpixels/sec
GeForce GTX 285 1GB 20736 Mpixels/sec
Difference: 11264 (54%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
