GeForce GT 1030 vs Radeon HD 3850 X2

Intro

The GeForce GT 1030 has a clock frequency of 1265 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 64-bit memory bus, and makes use of a 16 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare that to the Radeon HD 3850 X2, which comes with clock speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3850 X2 is 116% quicker than the GeForce GT 1030 overall, because of its greater bandwidth. (explain)

Radeon HD 3850 X2 105984 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 56832 (116%)

Texel Rate

The GeForce GT 1030 should be a lot (about 89%) faster with regards to texture filtering than the Radeon HD 3850 X2. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 3850 X2 21376 Mtexels/sec
Difference: 19104 (89%)

Pixel Rate

The Radeon HD 3850 X2 is a bit (approximately 6%) faster with regards to full screen anti-aliasing than the GeForce GT 1030, and capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 3850 X2 21376 Mpixels/sec
GeForce GT 1030 20240 Mpixels/sec
Difference: 1136 (6%)

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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
