GeForce 9500 GT DDR2 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also features 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT DDR2 should theoretically be a little bit faster than the Radeon R5 M330 in general. (explain)

GeForce 9500 GT DDR2		16000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R5 M330 will be a lot (about 134%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 11800 (134%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R5 M330 is a better choice, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 3840 (87%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
