GeForce GT 310 vs Radeon HD 4550 512MB

Intro

The GeForce GT 310 has core clock speeds of 589 MHz on the GPU, and 1000 MHz on the 512 MB of DDR2 memory. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Compare that to the Radeon HD 4550 512MB, which comes with GPU clock speed of 600 MHz, and 512 MB of GDDR3 memory set to run at 800 MHz through a 64-bit bus. It also features 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4550 512MB 25 Watts
GeForce GT 310 31 Watts
Difference: 6 Watts (24%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 310 is 25% faster than the Radeon HD 4550 512MB overall, due to its greater data rate. (explain)

GeForce GT 310 16000 MB/sec
Radeon HD 4550 512MB 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon HD 4550 512MB should be just a bit (approximately 2%) faster with regards to texture filtering than the GeForce GT 310. (explain)

Radeon HD 4550 512MB 4800 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 88 (2%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4550 512MB is the winner, but it probably won't make a huge difference. (explain)

Radeon HD 4550 512MB 2400 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 44 (2%)

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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
