GeForce GT 430 1GB vs Radeon R7 M265

Intro

The GeForce GT 430 1GB features a core clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Compare that to the Radeon R7 M265, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 is 11% quicker than the GeForce GT 430 1GB overall, due to its higher data rate. (explain)

Radeon R7 M265 32000 MB/sec
GeForce GT 430 1GB 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The Radeon R7 M265 is a lot (about 55%) more effective at AF than the GeForce GT 430 1GB. (explain)

Radeon R7 M265 17400 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 6200 (55%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M265 is a better choice, by a large margin. (explain)

Radeon R7 M265 5800 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 3000 (107%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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