Radeon R9 295X2 vs Radeon RX 6700 XT

Intro

Compare those specs to the Radeon RX 6700 XT, which uses a 7 nm design. AMD has clocked the core speed at 2321 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this specific card. It features 2560 SPUs as well as 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 295X2		500 Watts
	Difference: 270 Watts (117%)

Memory Bandwidth

In theory, the Radeon R9 295X2 should be 63% quicker than the Radeon RX 6700 XT in general, due to its greater data rate. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 246784 (63%)

Texel Rate

The Radeon RX 6700 XT will be a little bit (approximately 4%) more effective at texture filtering than the Radeon R9 295X2. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 295X2		358336 Mtexels/sec
	Difference: 13024 (4%)

Pixel Rate

The Radeon RX 6700 XT should be just a bit (about 14%) faster with regards to full screen anti-aliasing than the Radeon R9 295X2, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 295X2		130304 Mpixels/sec
	Difference: 18240 (14%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
