GeForce 9800 GT 1GB vs Radeon R7 250X

Intro

The GeForce 9800 GT 1GB has a core clock frequency of 600 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 ROPs.

Compare those specifications to the Radeon R7 250X, which has core speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

The Radeon R7 250X will be a small bit (about 19%) more effective at texture filtering than the GeForce 9800 GT 1GB. (explain)

Radeon R7 250X 40000 Mtexels/sec
GeForce 9800 GT 1GB 33600 Mtexels/sec
Difference: 6400 (19%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 250X is a better choice, by a large margin. (explain)

Radeon R7 250X 16000 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 6400 (67%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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