GeForce GTX 950 vs Radeon HD 5830

Intro

Compare all that to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular card. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950		90 Watts
Radeon HD 5830		175 Watts
	Difference: 85 Watts (94%)

Memory Bandwidth

Performance-wise, the Radeon HD 5830 should in theory be much superior to the GeForce GTX 950 overall. (explain)

Radeon HD 5830		128000 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 22272 (21%)

Texel Rate

The GeForce GTX 950 should be a small bit (more or less 10%) more effective at texture filtering than the Radeon HD 5830. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 4352 (10%)

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 HD 5830		12800 Mpixels/sec
	Difference: 19968 (156%)

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 MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one 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 the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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