GeForce 9500 GT 1GB GDDR3 vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
Radeon HD 7750		55 Watts
	Difference: 5 Watts (10%)

Memory Bandwidth

In theory, the Radeon HD 7750 should be 181% faster than the GeForce 9500 GT 1GB GDDR3 overall, due to its greater data rate. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon HD 7750 is much (about 191%) better at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 16800 (191%)

Pixel Rate

The Radeon HD 7750 should be quite a bit (more or less 191%) faster with regards to full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and also able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 8400 (191%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
