GeForce GTX 1050 vs Radeon HD 4770

Intro

Compare all that to the Radeon HD 4770, which comes with a GPU core clock speed of 750 MHz, and 512 MB of GDDR5 RAM running at 800 MHz through a 128-bit bus. It also is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050		75 Watts
Radeon HD 4770		80 Watts
	Difference: 5 Watts (7%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 is 124% faster than the Radeon HD 4770 in general, due to its greater bandwidth. (explain)

GeForce GTX 1050		114688 MB/sec
Radeon HD 4770		51200 MB/sec
	Difference: 63488 (124%)

Texel Rate

The GeForce GTX 1050 will be much (about 126%) more effective at anisotropic filtering than the Radeon HD 4770. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 4770		24000 Mtexels/sec
	Difference: 30160 (126%)

Pixel Rate

The GeForce GTX 1050 should be quite a bit (about 261%) faster with regards to FSAA than the Radeon HD 4770, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 4770		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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
