GeForce GT 340 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which has a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 340 should theoretically perform much faster than the Radeon R5 M230 in general. (explain)

GeForce GT 340		54400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 will be a small bit (about 13%) faster with regards to texture filtering than the Radeon R5 M230. (explain)

GeForce GT 340		17600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 2000 (13%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 340 is superior to the Radeon R5 M230, by far. (explain)

GeForce GT 340		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
