GeForce GT 130 vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which features a clock frequency of 1030 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M330 should perform just a bit faster than the GeForce GT 130 overall. (explain)

Radeon R5 M330		14400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 2400 (20%)

Texel Rate

The Radeon R5 M330 will be quite a bit (about 72%) better at AF than the GeForce GT 130. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 8600 (72%)

Pixel Rate

The Radeon R5 M330 should be a little bit (about 3%) more effective at full screen anti-aliasing than the GeForce GT 130, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 240 (3%)

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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
