VS

GeForce GTX 1070 vs Radeon RX 6600 XT

Intro

The GeForce GTX 1070 has clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 1920 SPUs along with 120 TAUs and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6600 XT, which has a core clock frequency of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070 150 Watts
Radeon RX 6600 XT 160 Watts
Difference: 10 Watts (7%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon RX 6600 XT will be a lot (about 39%) faster with regards to AF than the GeForce GTX 1070. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
GeForce GTX 1070 180720 Mtexels/sec
Difference: 71184 (39%)

Pixel Rate

The Radeon RX 6600 XT will be much (more or less 31%) better at AA than the GeForce GTX 1070, and should be capable of handling higher resolutions better. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
GeForce GTX 1070 96384 Mpixels/sec
Difference: 29568 (31%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
