GeForce GTX 1050 vs Radeon HD 4890 2GB

Intro

The GeForce GTX 1050 comes with a core clock frequency of 1354 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It is comprised of 640 SPUs, 40 TAUs, and 32 ROPs.

Compare those specifications to the Radeon HD 4890 2GB, which comes with a clock speed of 1000 MHz and a GDDR5 memory frequency of 975 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 75 Watts
Radeon HD 4890 2GB 190 Watts
Difference: 115 Watts (153%)

Memory Bandwidth

As far as performance goes, the Radeon HD 4890 2GB should in theory be just a bit superior to the GeForce GTX 1050 in general. (explain)

Radeon HD 4890 2GB 124800 MB/sec
GeForce GTX 1050 114688 MB/sec
Difference: 10112 (9%)

Texel Rate

The GeForce GTX 1050 should be quite a bit (about 35%) faster with regards to texture filtering than the Radeon HD 4890 2GB. (explain)

GeForce GTX 1050 54160 Mtexels/sec
Radeon HD 4890 2GB 40000 Mtexels/sec
Difference: 14160 (35%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1050 is the winner, and very much so. (explain)

GeForce GTX 1050 43328 Mpixels/sec
Radeon HD 4890 2GB 16000 Mpixels/sec
Difference: 27328 (171%)

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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 reach the maximum fill rate.
