GeForce GTX 1050 vs Radeon HD 4850 X2 512MB

Intro

The GeForce GTX 1050 makes use of a 14 nm design. nVidia has clocked the core frequency at 1354 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon HD 4850 X2 512MB, which features a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory set to run at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 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 4850 X2 512MB 250 Watts
Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 512MB is 11% faster than the GeForce GTX 1050 in general, because of its higher bandwidth. (explain)

Radeon HD 4850 X2 512MB 127104 MB/sec
GeForce GTX 1050 114688 MB/sec
Difference: 12416 (11%)

Texel Rate

The GeForce GTX 1050 should be just a bit (approximately 8%) faster with regards to anisotropic filtering than the Radeon HD 4850 X2 512MB. (explain)

GeForce GTX 1050 54160 Mtexels/sec
Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Difference: 4160 (8%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 is superior to the Radeon HD 4850 X2 512MB, by a large margin. (explain)

GeForce GTX 1050 43328 Mpixels/sec
Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Difference: 23328 (117%)

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 data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
