GeForce 9500 GT 1GB GDDR3 vs Radeon R9 M265X

Intro

The GeForce 9500 GT 1GB GDDR3 comes with a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare that to the Radeon R9 M265X, which has a clock frequency of 575 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M265X should in theory be much faster than the GeForce 9500 GT 1GB GDDR3 overall. (explain)

Radeon R9 M265X 72000 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 46400 (181%)

Texel Rate

The Radeon R9 M265X will be a lot (more or less 161%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R9 M265X 23000 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 14200 (161%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M265X is the winner, by a large margin. (explain)

Radeon R9 M265X 9200 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 4800 (109%)

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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one 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 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied in one second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its 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 core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
