GeForce 9500 GT 512MB GDDR3 vs GeForce GTS 150

Intro

The GeForce 9500 GT 512MB GDDR3 has a GPU core speed of 550 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce GTS 150, which comes with a clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3 50 Watts
GeForce GTS 150 141 Watts
Difference: 91 Watts (182%)

Memory Bandwidth

In theory, the GeForce GTS 150 is 25% quicker than the GeForce 9500 GT 512MB GDDR3 in general, due to its higher data rate. (explain)

GeForce GTS 150 32000 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 6400 (25%)

Texel Rate

The GeForce GTS 150 should be a lot (about 438%) more effective at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTS 150 47360 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 38560 (438%)

Pixel Rate

The GeForce GTS 150 will be much (more or less 169%) faster with regards to anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTS 150 11840 Mpixels/sec
GeForce 9500 GT 512MB 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 MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
