VS

GeForce 9500 GT 1GB GDDR3 vs GeForce GT 430 (OEM)

Intro

The GeForce 9500 GT 1GB GDDR3 features a GPU clock speed of 550 MHz, and the 1024 MB of GDDR3 RAM runs at 800 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the GeForce GT 430 (OEM), which uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3 50 Watts
GeForce GT 430 (OEM) 60 Watts
Difference: 10 Watts (20%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 (OEM) should be 13% quicker than the GeForce 9500 GT 1GB GDDR3 in general, because of its greater data rate. (explain)

GeForce GT 430 (OEM) 28800 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 3200 (13%)

Texel Rate

The GeForce GT 430 (OEM) should be quite a bit (about 27%) better at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GT 430 (OEM) 11200 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 2400 (27%)

Pixel Rate

The GeForce 9500 GT 1GB GDDR3 should be a lot (about 57%) faster with regards to anti-aliasing than the GeForce GT 430 (OEM), and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 1600 (57%)

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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 the texel rate, the better the graphics 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour 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 output 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 get to the maximum fill rate.
