GeForce 920M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 920M comes with clock speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the GeForce 9500 GT 1GB GDDR3, which has a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 9500 GT 1GB GDDR3 should in theory be a lot better than the GeForce 920M overall. (explain)

GeForce 9500 GT 1GB GDDR3 25600 MB/sec
GeForce 920M 14400 MB/sec
Difference: 11200 (78%)

Texel Rate

The GeForce 920M is a lot (approximately 247%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 21728 (247%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 920M is the winner, by far. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 3232 (73%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core 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 many 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.
