GeForce 9500 GT 512MB GDDR3 vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which has GPU core speed of 1168 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3		50 Watts
Radeon RX 570		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

The Radeon RX 570, in theory, should be quite a bit faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)

Radeon RX 570		229376 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 203776 (796%)

Texel Rate

The Radeon RX 570 should be much (approximately 1599%) more effective at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 140704 (1599%)

Pixel Rate

The Radeon RX 570 should be much (more or less 749%) more effective at full screen anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 32976 (749%)

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 max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
