GeForce GT 430 1GB vs Radeon R7 M265

Intro

Compare that to the Radeon R7 M265, which comes with a clock speed of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M265 should be a bit faster than the GeForce GT 430 1GB in general. (explain)

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

Texel Rate

The Radeon R7 M265 will be quite a bit (more or less 55%) faster with regards to texture filtering 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 using lots of anti-aliasing is important to you, then the Radeon R7 M265 is superior to the GeForce GT 430 1GB, and very much so. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 potential to get to the max fill rate.
