Radeon R7 250X 2GB vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which makes use of a 7 nm design. AMD has clocked the core frequency at 1465 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this specific model. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X 2GB		95 Watts
Radeon RX 5700		180 Watts
	Difference: 85 Watts (89%)

Memory Bandwidth

In theory, the Radeon RX 5700 should be 537% quicker than the Radeon R7 250X 2GB in general, because of its higher data rate. (explain)

Radeon RX 5700		458752 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 386752 (537%)

Texel Rate

The Radeon RX 5700 will be much (about 427%) better at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

Radeon RX 5700		210960 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 170960 (427%)

Pixel Rate

The Radeon RX 5700 will be quite a bit (more or less 486%) better at anti-aliasing than the Radeon R7 250X 2GB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 77760 (486%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core 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 chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
