GeForce 9500 GT 1GB GDDR3 vs GeForce GTS 150

Intro

The GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM works at a speed of 800 MHz on this particular card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the GeForce GTS 150, which comes with GPU clock speed of 740 MHz, and 1024 MB of GDDR3 RAM running at 500 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

GeForce GTS 150 32000 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 6400 (25%)

Texel Rate

The GeForce GTS 150 will be a lot (about 438%) better at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTS 150 47360 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 38560 (438%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTS 150 is the winner, by far. (explain)

GeForce GTS 150 11840 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 7440 (169%)

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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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.
