GeForce GT 130 vs Radeon HD 6670 (OEM)

Intro

Compare those specs to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6670 (OEM)		63 Watts
GeForce GT 130		75 Watts
	Difference: 12 Watts (19%)

Memory Bandwidth

In theory, the Radeon HD 6670 (OEM) should perform a lot faster than the GeForce GT 130 overall. (explain)

Radeon HD 6670 (OEM)		64000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 52000 (433%)

Texel Rate

The Radeon HD 6670 (OEM) should be quite a bit (more or less 60%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

Radeon HD 6670 (OEM)		19200 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 7200 (60%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 130 is a better choice, by a large margin. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon HD 6670 (OEM)		6400 Mpixels/sec
	Difference: 1600 (25%)

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 (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core 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 per second.

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