Compare any two graphics cards:
VS

Radeon R9 295X2 vs Radeon RX 6950 XT

Intro

The Radeon R9 295X2 has a GPU core speed of 1018 MHz, and the 4096 MB of GDDR5 memory runs at 1250 MHz through a 512-bit bus. It also is comprised of 2816 Stream Processors, 176 TAUs, and 64 ROPs.

Compare all that to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has set the core speed at 1925 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this model. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6950 XT 335 Watts
Radeon R9 295X2 500 Watts
Difference: 165 Watts (49%)

Memory Bandwidth

In theory, the Radeon R9 295X2 should perform a little bit faster than the Radeon RX 6950 XT overall. (explain)

Radeon R9 295X2 640000 MB/sec
Radeon RX 6950 XT 589824 MB/sec
Difference: 50176 (9%)

Texel Rate

The Radeon RX 6950 XT is a lot (approximately 72%) faster with regards to AF than the Radeon R9 295X2. (explain)

Radeon RX 6950 XT 616000 Mtexels/sec
Radeon R9 295X2 358336 Mtexels/sec
Difference: 257664 (72%)

Pixel Rate

The Radeon RX 6950 XT is quite a bit (about 89%) better at AA than the Radeon R9 295X2, and also capable of handling higher resolutions more effectively. (explain)

Radeon RX 6950 XT 246400 Mpixels/sec
Radeon R9 295X2 130304 Mpixels/sec
Difference: 116096 (89%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
