GeForce GTX 1050 vs Radeon HD 4870 1GB

Intro

Compare all of that to the Radeon HD 4870 1GB, which uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory works at a speed of 900 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050		75 Watts
Radeon HD 4870 1GB		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Performance-wise, the Radeon HD 4870 1GB should in theory be just a bit better than the GeForce GTX 1050 overall. (explain)

Radeon HD 4870 1GB		115200 MB/sec
GeForce GTX 1050		114688 MB/sec
	Difference: 512 (0%)

Texel Rate

The GeForce GTX 1050 should be a lot (approximately 81%) more effective at AF than the Radeon HD 4870 1GB. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 4870 1GB		30000 Mtexels/sec
	Difference: 24160 (81%)

Pixel Rate

The GeForce GTX 1050 should be quite a bit (more or less 261%) more effective at full screen anti-aliasing than the Radeon HD 4870 1GB, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 4870 1GB		12000 Mpixels/sec
	Difference: 31328 (261%)

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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
