GeForce GTX 1050 Ti vs Radeon HD 4850 X2 1GB

Intro

The GeForce GTX 1050 Ti makes use of a 14 nm design. nVidia has clocked the core frequency at 1290 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this specific model. It features 768 SPUs along with 48 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon HD 4850 X2 1GB, which comes with GPU clock speed of 625 MHz, and 1024 MB of GDDR3 memory running at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

The GeForce GTX 1050 Ti will be much (about 24%) faster with regards to anisotropic filtering than the Radeon HD 4850 X2 1GB. (explain)

GeForce GTX 1050 Ti 61920 Mtexels/sec
Radeon HD 4850 X2 1GB 50000 Mtexels/sec
Difference: 11920 (24%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1050 Ti is superior to the Radeon HD 4850 X2 1GB, by far. (explain)

GeForce GTX 1050 Ti 41280 Mpixels/sec
Radeon HD 4850 X2 1GB 20000 Mpixels/sec
Difference: 21280 (106%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
