GeForce GT 230 vs Radeon R9 M380

Intro

Compare that to the Radeon R9 M380, which has a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should theoretically be quite a bit faster than the GeForce GT 230 overall. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The Radeon R9 M380 is a lot (more or less 355%) more effective at texture filtering than the GeForce GT 230. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 31200 (355%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M380 is superior to the GeForce GT 230, and very much so. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 11600 (264%)

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 (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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