GeForce GT 340 1GB vs Radeon R5 M230

Intro

The GeForce GT 340 1GB comes with a GPU core clock speed of 550 MHz, and the 1024 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.

Compare all that to the Radeon R5 M230, which comes with a core clock frequency of 780 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 1GB is 240% faster than the Radeon R5 M230 in general, due to its greater data rate. (explain)

GeForce GT 340 1GB 54400 MB/sec
Radeon R5 M230 16000 MB/sec
Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 1GB should be a bit (more or less 13%) more effective at AF than the Radeon R5 M230. (explain)

GeForce GT 340 1GB 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 1GB is a better choice, by far. (explain)

GeForce GT 340 1GB 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
