GeForce GT 230 vs Radeon R7 M265

Intro

The GeForce GT 230 comes with a GPU clock speed of 550 MHz, and the 1536 MB of DDR3 memory runs at 800 MHz through a 192-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the Radeon R7 M265, which comes with a core clock frequency of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

The GeForce GT 230 should theoretically be a little bit faster than the Radeon R7 M265 in general. (explain)

GeForce GT 230 38400 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 6400 (20%)

Texel Rate

The Radeon R7 M265 will be quite a bit (approximately 98%) faster with regards to AF than the GeForce GT 230. (explain)

Radeon R7 M265 17400 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 8600 (98%)

Pixel Rate

The Radeon R7 M265 is quite a bit (more or less 32%) better at AA than the GeForce GT 230, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R7 M265 5800 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 1400 (32%)

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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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