VS

GeForce GTX 1630 vs Radeon HD 7990

Intro

The GeForce GTX 1630 comes with clock speeds of 1740 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR6 memory. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon HD 7990, which makes use of a 28 nm design. AMD has set the core speed at 950 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630 75 Watts
Radeon HD 7990 375 Watts
Difference: 300 Watts (400%)

Memory Bandwidth

The Radeon HD 7990, in theory, should be a lot faster than the GeForce GTX 1630 in general. (explain)

Radeon HD 7990 576000 MB/sec
GeForce GTX 1630 98304 MB/sec
Difference: 477696 (486%)

Texel Rate

The Radeon HD 7990 will be quite a bit (more or less 337%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon HD 7990 243200 Mtexels/sec
GeForce GTX 1630 55680 Mtexels/sec
Difference: 187520 (337%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 7990 is a better choice, by a large margin. (explain)

Radeon HD 7990 60800 Mpixels/sec
GeForce GTX 1630 27840 Mpixels/sec
Difference: 32960 (118%)

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 information (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out 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 it uses 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
