GeForce GT 230 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which comes with a clock frequency of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GT 230 should in theory be quite a bit better than the Radeon R5 M230 in general. (explain)

GeForce GT 230		38400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 22400 (140%)

Texel Rate

The Radeon R5 M230 will be a lot (about 77%) faster with regards to AF than the GeForce GT 230. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 230 is superior to the Radeon R5 M230, by far. (explain)

GeForce GT 230		4400 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1280 (41%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
