GeForce GT 130 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which comes with GPU clock speed of 1030 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also 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 be 20% faster than the GeForce GT 130 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon R5 M330 will be much (approximately 72%) more effective at anisotropic filtering 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 bit (approximately 3%) better at anti-aliasing than the GeForce GT 130, and will be capable of handling higher screen resolutions without slowing down too much. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock 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 processed in a second.

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