GeForce GT 1030 vs Radeon HD 3870 X2 1GB

Intro

The GeForce GT 1030 features a clock speed 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 features 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare all of that to the Radeon HD 3870 X2 1GB, which uses a 55 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR4 RAM runs at a frequency of 1126 MHz on this specific model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3870 X2 1GB should be 193% quicker than the GeForce GT 1030 in general, due to its greater bandwidth. (explain)

Radeon HD 3870 X2 1GB 144128 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 94976 (193%)

Texel Rate

The GeForce GT 1030 will be much (approximately 53%) more effective at AF than the Radeon HD 3870 X2 1GB. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 3870 X2 1GB 26400 Mtexels/sec
Difference: 14080 (53%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 3870 X2 1GB is a better choice, by a large margin. (explain)

Radeon HD 3870 X2 1GB 26400 Mpixels/sec
GeForce GT 1030 20240 Mpixels/sec
Difference: 6160 (30%)

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 transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
