GeForce GTS 250 1GB vs Radeon HD 4670 512MB

Intro

The GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 RAM is set to run at a frequency of 1100 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 4670 512MB, which comes with clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 4670 512MB 32000 MB/sec
Difference: 38400 (120%)

Texel Rate

The GeForce GTS 250 1GB should be quite a bit (about 97%) more effective at AF than the Radeon HD 4670 512MB. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
Radeon HD 4670 512MB 24000 Mtexels/sec
Difference: 23232 (97%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTS 250 1GB is the winner, and very much so. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
Radeon HD 4670 512MB 6000 Mpixels/sec
Difference: 5808 (97%)

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 largest amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of 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.
