GeForce GTX 460 (OEM) vs Radeon HD 5550

Intro

The GeForce GTX 460 (OEM) comes with a GPU core speed of 650 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon HD 5550, which features core speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) will be 750% quicker than the Radeon HD 5550 overall, due to its higher bandwidth. (explain)

GeForce GTX 460 (OEM) 108800 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 96000 (750%)

Texel Rate

The GeForce GTX 460 (OEM) will be a lot (about 314%) more effective at texture filtering than the Radeon HD 5550. (explain)

GeForce GTX 460 (OEM) 36400 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 27600 (314%)

Pixel Rate

The GeForce GTX 460 (OEM) should be quite a bit (about 373%) more effective at FSAA than the Radeon HD 5550, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 (OEM) 20800 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 16400 (373%)

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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
