GeForce 9500 GT 512MB GDDR3 vs Radeon HD 7750

Intro

Compare those specs to the Radeon HD 7750, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this specific card. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3		50 Watts
Radeon HD 7750		55 Watts
	Difference: 5 Watts (10%)

Memory Bandwidth

The Radeon HD 7750, in theory, should perform a lot faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon HD 7750 will be quite a bit (approximately 191%) better at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 16800 (191%)

Pixel Rate

The Radeon HD 7750 should be much (more or less 191%) faster with regards to FSAA than the GeForce 9500 GT 512MB GDDR3, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9500 GT 512MB 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 data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
