GeForce 9500 GT 1GB GDDR3 vs Radeon R9 M270X

Intro

Compare those specifications to the Radeon R9 M270X, which features GPU core speed of 725 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X is 181% faster than the GeForce 9500 GT 1GB GDDR3 overall, due to its higher bandwidth. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R9 M270X is quite a bit (about 230%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R9 M270X		29000 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 20200 (230%)

Pixel Rate

The Radeon R9 M270X is a lot (more or less 164%) more effective at AA than the GeForce 9500 GT 1GB GDDR3, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M270X		11600 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 7200 (164%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the potential to reach the max fill rate.
