GeForce GT 230 vs Radeon R9 270X

Intro

Compare those specifications to the Radeon R9 270X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this specific model. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Radeon R9 270X		180 Watts
	Difference: 115 Watts (177%)

Memory Bandwidth

In theory, the Radeon R9 270X is 367% faster than the GeForce GT 230 in general, because of its higher data rate. (explain)

Radeon R9 270X		179200 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 140800 (367%)

Texel Rate

The Radeon R9 270X will be quite a bit (about 809%) better at texture filtering than the GeForce GT 230. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 71200 (809%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 270X is the winner, and very much so. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 27600 (627%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 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 potential to reach the max fill rate.
