Radeon R9 290 vs Radeon RX 6700 XT

Intro

The Radeon R9 290 has a GPU core speed of 800 MHz, and the 4096 MB of GDDR5 memory runs at 1250 MHz through a 512-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare that to the Radeon RX 6700 XT, which uses a 7 nm design. AMD has set the core frequency at 2321 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6700 XT 230 Watts
Radeon R9 290 300 Watts
Difference: 70 Watts (30%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT will be 23% faster than the Radeon R9 290 in general, because of its higher data rate. (explain)

Radeon RX 6700 XT 393216 MB/sec
Radeon R9 290 320000 MB/sec
Difference: 73216 (23%)

Texel Rate

The Radeon RX 6700 XT will be quite a bit (approximately 190%) better at anisotropic filtering than the Radeon R9 290. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
Radeon R9 290 128000 Mtexels/sec
Difference: 243360 (190%)

Pixel Rate

The Radeon RX 6700 XT is quite a bit (about 190%) better at AA than the Radeon R9 290, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
Radeon R9 290 51200 Mpixels/sec
Difference: 97344 (190%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
