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

Intro

The GeForce 9500 GT 1GB GDDR3 uses 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 particular model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the GeForce GT 440 1.5GB, which comes with a core clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

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

Performance-wise, the GeForce GT 440 1.5GB should in theory be a lot superior to the GeForce 9500 GT 1GB GDDR3 overall. (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 will be much (more or less 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

If using lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce 9500 GT 1GB GDDR3, and very much so. (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 information (in units of MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
