GeForce GTX 950 vs Radeon R5 M330

Intro

Compare all that 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 memory bus, and makes use of a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 950 should in theory be a lot better than the Radeon R5 M330 in general. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 91328 (634%)

Texel Rate

The GeForce GTX 950 is a lot (more or less 139%) better at AF than the Radeon R5 M330. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 28552 (139%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 950 is a better choice, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 24528 (298%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
