GeForce 9500 GT 1GB GDDR3 vs GeForce GT 440 1.5GB

Intro

The GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 memory runs at a speed of 800 MHz on this specific card. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare all that to the GeForce GT 440 1.5GB, which features a GPU core clock speed of 594 MHz, and 1536 MB of GDDR3 RAM set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3 50 Watts
GeForce GT 440 1.5GB 56 Watts
Difference: 6 Watts (12%)

Memory Bandwidth

In theory, the GeForce GT 440 1.5GB will be 69% faster than the GeForce 9500 GT 1GB GDDR3 in general, because of its greater data rate. (explain)

GeForce GT 440 1.5GB 43200 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 17600 (69%)

Texel Rate

The GeForce GT 440 1.5GB should be quite a bit (about 62%) faster with regards to texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GT 440 1.5GB 14256 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 5456 (62%)

Pixel Rate

The GeForce GT 440 1.5GB is a lot (more or less 224%) better at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 440 1.5GB 14256 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 9856 (224%)

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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few 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.
