GeForce 9500 GT 512MB GDDR3 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which comes with clock speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 9500 GT 512MB GDDR3 should be quite a bit faster than the Radeon R5 M230 in general. (explain)

GeForce 9500 GT 512MB GDDR3		25600 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 9600 (60%)

Texel Rate

The Radeon R5 M230 is much (more or less 77%) more effective at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

The GeForce 9500 GT 512MB GDDR3 is quite a bit (about 41%) more effective at full screen anti-aliasing than the Radeon R5 M230, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce 9500 GT 512MB GDDR3		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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
