GeForce GTX 1050 Ti vs Radeon HD 4790

Intro

The GeForce GTX 1050 Ti uses a 14 nm design. nVidia has clocked the core frequency at 1290 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this particular card. It features 768 SPUs along with 48 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4790, which has core speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 Ti will be 12% faster than the Radeon HD 4790 overall, due to its higher bandwidth. (explain)

GeForce GTX 1050 Ti 114688 MB/sec
Radeon HD 4790 102400 MB/sec
Difference: 12288 (12%)

Texel Rate

The GeForce GTX 1050 Ti should be a lot (about 223%) better at AF than the Radeon HD 4790. (explain)

GeForce GTX 1050 Ti 61920 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 42720 (223%)

Pixel Rate

The GeForce GTX 1050 Ti is quite a bit (more or less 330%) better at anti-aliasing than the Radeon HD 4790, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1050 Ti 41280 Mpixels/sec
Radeon HD 4790 9600 Mpixels/sec
Difference: 31680 (330%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
