GeForce GTX 1050 3GB vs Radeon HD 4850 X2 1GB

Intro

Compare all of that to the Radeon HD 4850 X2 1GB, which features core clock speeds of 625 MHz on the GPU, and 993 MHz on the 1024 MB of GDDR3 memory. 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 3GB		75 Watts
Radeon HD 4850 X2 1GB		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 1GB should be quite a bit faster than the GeForce GTX 1050 3GB in general. (explain)

Radeon HD 4850 X2 1GB		127104 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 41088 (48%)

Texel Rate

The GeForce GTX 1050 3GB is much (about 34%) faster with regards to texture filtering than the Radeon HD 4850 X2 1GB. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon HD 4850 X2 1GB		50000 Mtexels/sec
	Difference: 16816 (34%)

Pixel Rate

The GeForce GTX 1050 3GB should be a lot (more or less 67%) more effective at anti-aliasing than the Radeon HD 4850 X2 1GB, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon HD 4850 X2 1GB		20000 Mpixels/sec
	Difference: 13408 (67%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
