GeForce GTX 1050 vs Radeon HD 5850

Intro

Compare all of that to the Radeon HD 5850, which uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 1440(288x5) SPUs as well as 72 Texture Address Units and 32 Rasterization Operator Units.

Texel Rate

The GeForce GTX 1050 is just a bit (approximately 4%) better at texture filtering than the Radeon HD 5850. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 1960 (4%)

Pixel Rate

The GeForce GTX 1050 is a lot (about 87%) better at FSAA than the Radeon HD 5850, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 20128 (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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
