GeForce GT 1030 vs Radeon HD 3870 X2 1GB

Intro

The GeForce GT 1030 comes with clock speeds of 1265 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 3870 X2 1GB, which comes with GPU clock speed of 825 MHz, and 1024 MB of GDDR4 RAM running at 1126 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 3870 X2 1GB should in theory be much superior to the GeForce GT 1030 in general. (explain)

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

Texel Rate

The GeForce GT 1030 should be a lot (about 53%) faster with regards to texture filtering 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

The Radeon HD 3870 X2 1GB is much (more or less 30%) more effective at anti-aliasing than the GeForce GT 1030, and also should be able to handle higher resolutions more effectively. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
