Radeon R9 295X2 vs Radeon RX 5700

Intro

Compare all that to the Radeon RX 5700, which comes with GPU core speed of 1465 MHz, and 8096 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Radeon R9 295X2		500 Watts
	Difference: 320 Watts (178%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 295X2 should be 40% faster than the Radeon RX 5700 in general, because of its higher data rate. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 181248 (40%)

Texel Rate

The Radeon R9 295X2 is quite a bit (more or less 70%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 147376 (70%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 295X2 is a better choice, and very much so. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 36544 (39%)

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 data (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
