GeForce 9500 GT 1GB GDDR3 vs GeForce GT 315

Intro

The GeForce 9500 GT 1GB GDDR3 features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare those specifications to the GeForce GT 315, which has core clock speeds of 625 MHz on the GPU, and 790 MHz on the 512 MB of DDR3 RAM. It features 48 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3 50 Watts
GeForce GT 315 52 Watts
Difference: 2 Watts (4%)

Memory Bandwidth

The GeForce 9500 GT 1GB GDDR3, in theory, should be a small bit faster than the GeForce GT 315 overall. (explain)

GeForce 9500 GT 1GB GDDR3 25600 MB/sec
GeForce GT 315 25280 MB/sec
Difference: 320 (1%)

Texel Rate

The GeForce GT 315 is a little bit (approximately 14%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GT 315 10000 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 1200 (14%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 315 is superior to the GeForce 9500 GT 1GB GDDR3, though only just barely. (explain)

GeForce GT 315 5000 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 600 (14%)

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 maximum amount of information (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
