GeForce 9500 GT 1GB GDDR3 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which comes with a clock frequency of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 12 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
Radeon RX 590		175 Watts
	Difference: 125 Watts (250%)

Memory Bandwidth

The Radeon RX 590, in theory, should perform quite a bit faster than the GeForce 9500 GT 1GB GDDR3 overall. (explain)

Radeon RX 590		262144 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 236544 (924%)

Texel Rate

The Radeon RX 590 should be a lot (about 2304%) better at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 202736 (2304%)

Pixel Rate

The Radeon RX 590 will be a lot (approximately 968%) faster with regards to anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to reach the max fill rate.
