GeForce 9500 GT DDR2 vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which has GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
Radeon RX 590		175 Watts
	Difference: 125 Watts (250%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 590 should be 1538% quicker than the GeForce 9500 GT DDR2 in general, because of its higher data rate. (explain)

Radeon RX 590		262144 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 246144 (1538%)

Texel Rate

The Radeon RX 590 should be a lot (about 2304%) more effective at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 202736 (2304%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 590 is a better choice, and very much so. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 42608 (968%)

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 data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
