GeForce GTS 450 1GB vs Radeon R9 M265X

Intro

The GeForce GTS 450 1GB comes with a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 RAM is set to run at 902 MHz through a 128-bit bus. It also is made up of 192 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon R9 M265X, which has a core clock speed of 575 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTS 450 1GB 57728 MB/sec
Difference: 14272 (25%)

Texel Rate

The GeForce GTS 450 1GB should be a small bit (about 9%) better at AF than the Radeon R9 M265X. (explain)

GeForce GTS 450 1GB 25056 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 2056 (9%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTS 450 1GB is a better choice, and very much so. (explain)

GeForce GTS 450 1GB 12528 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 3328 (36%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, 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 that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
