GeForce 9500 GT DDR2 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with a clock frequency of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 9500 GT DDR2 should be a small bit faster than the Radeon R5 M330 overall. (explain)

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

Texel Rate

The Radeon R5 M330 should be a lot (more or less 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

The Radeon R5 M330 should be quite a bit (approximately 87%) better at FSAA than the GeForce 9500 GT DDR2, and should be capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface 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 4 instead. The higher the card's 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 processed per second. This is calculated by multiplying the total number of texture units of the card 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
