VS

GeForce GTX 1630 vs Radeon HD 6990

Intro

The GeForce GTX 1630 has core speeds of 1740 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR6 memory. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Compare those specs to the Radeon HD 6990, which has core clock speeds of 830 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 96 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630 75 Watts
Radeon HD 6990 375 Watts
Difference: 300 Watts (400%)

Memory Bandwidth

The Radeon HD 6990, in theory, should be quite a bit faster than the GeForce GTX 1630 in general. (explain)

Radeon HD 6990 320000 MB/sec
GeForce GTX 1630 98304 MB/sec
Difference: 221696 (226%)

Texel Rate

The Radeon HD 6990 will be quite a bit (approximately 186%) more effective at texture filtering than the GeForce GTX 1630. (explain)

Radeon HD 6990 159360 Mtexels/sec
GeForce GTX 1630 55680 Mtexels/sec
Difference: 103680 (186%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6990 is the winner, and very much so. (explain)

Radeon HD 6990 53120 Mpixels/sec
GeForce GTX 1630 27840 Mpixels/sec
Difference: 25280 (91%)

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 maximum amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
