GeForce 930M vs GeForce 9500 GT 512MB GDDR3

Intro

Compare those specifications to the GeForce 9500 GT 512MB GDDR3, which uses a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 memory works at a frequency of 800 MHz on this specific card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT 512MB GDDR3 should in theory perform a lot faster than the GeForce 930M overall. (explain)

GeForce 9500 GT 512MB GDDR3		25600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 930M will be a lot (more or less 153%) faster with regards to anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 13472 (153%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 930M is superior to the GeForce 9500 GT 512MB GDDR3, and very much so. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 3024 (69%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
