GeForce 9500 GT 512MB GDDR3 vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce 9500 GT 512MB GDDR3 has core speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon HD 6570 (OEM) 1GB, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also features 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon HD 6570 (OEM) 1GB should be 13% faster than the GeForce 9500 GT 512MB GDDR3 overall, due to its greater bandwidth. (explain)

Radeon HD 6570 (OEM) 1GB 28800 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 3200 (13%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be quite a bit (approximately 77%) more effective at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 6800 (77%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6570 (OEM) 1GB is superior to the GeForce 9500 GT 512MB GDDR3, but it probably won't make a huge difference. (explain)

Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
GeForce 9500 GT 512MB GDDR3 4400 Mpixels/sec
Difference: 800 (18%)

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 largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 maximum fill rate.
