GeForce 9500 GT 512MB GDDR3 vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core frequency at 780 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9500 GT 512MB GDDR3 is 60% quicker than the Radeon R5 M230 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon R5 M230 will be much (about 77%) faster with regards to texture filtering 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

If using a high screen resolution is important to you, then the GeForce 9500 GT 512MB GDDR3 is superior to the Radeon R5 M230, by a large margin. (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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
