GeForce GT 230 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which uses a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 memory works at a frequency of 1000 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 230 should be 140% faster than the Radeon R5 M230 in general, because of its higher bandwidth. (explain)

GeForce GT 230		38400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 22400 (140%)

Texel Rate

The Radeon R5 M230 is a lot (approximately 77%) more effective at AF than the GeForce GT 230. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

The GeForce GT 230 is quite a bit (more or less 41%) more effective at FSAA than the Radeon R5 M230, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GT 230		4400 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1280 (41%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
