GeForce GT 230 vs Radeon R7 250X

Intro

The GeForce GT 230 comes with a GPU core speed of 550 MHz, and the 1536 MB of DDR3 memory is set to run at 800 MHz through a 192-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all of that to the Radeon R7 250X, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

GeForce GT 230 38400 MB/sec
Difference: 33600 (88%)

Texel Rate

The Radeon R7 250X will be a lot (approximately 355%) more effective at AF than the GeForce GT 230. (explain)

Radeon R7 250X 40000 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 31200 (355%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 250X is the winner, by a large margin. (explain)

Radeon R7 250X 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
