GeForce GT 240 GDDR5 1GB vs Radeon HD 6570 (OEM) 2GB

Intro

The GeForce GT 240 GDDR5 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this card. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.

Compare those specs to the Radeon HD 6570 (OEM) 2GB, which comes with a clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Radeon HD 6570 (OEM) 2GB 50 Watts
GeForce GT 240 GDDR5 1GB 70 Watts
Difference: 20 Watts (40%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6570 (OEM) 2GB should be just a bit faster than the GeForce GT 240 GDDR5 1GB in general. (explain)

Radeon HD 6570 (OEM) 2GB 64000 MB/sec
GeForce GT 240 GDDR5 1GB 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The GeForce GT 240 GDDR5 1GB will be just a bit (about 13%) faster with regards to AF than the Radeon HD 6570 (OEM) 2GB. (explain)

GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 2000 (13%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6570 (OEM) 2GB is superior to the GeForce GT 240 GDDR5 1GB, but it probably won't make a huge difference. (explain)

Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
Difference: 800 (18%)

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 data (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
