GeForce 9500 GT DDR2 vs Radeon R7 250

Intro

The GeForce 9500 GT DDR2 comes with a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also features a 128-bit bus, and makes use of a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the Radeon R7 250, which comes with clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

GeForce 9500 GT DDR2 16000 MB/sec
Difference: 57600 (360%)

Texel Rate

The Radeon R7 250 should be quite a bit (more or less 173%) faster with regards to AF than the GeForce 9500 GT DDR2. (explain)

Radeon R7 250 24000 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 15200 (173%)

Pixel Rate

The Radeon R7 250 should be quite a bit (approximately 82%) better at AA than the GeForce 9500 GT DDR2, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R7 250 8000 Mpixels/sec
GeForce 9500 GT DDR2 4400 Mpixels/sec
Difference: 3600 (82%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
