GeForce GTS 150 vs Radeon RX 570

Intro

Compare those specifications to the Radeon RX 570, which has clock speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTS 150		141 Watts
Radeon RX 570		150 Watts
	Difference: 9 Watts (6%)

Memory Bandwidth

As far as performance goes, the Radeon RX 570 should in theory be quite a bit better than the GeForce GTS 150 overall. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 197376 (617%)

Texel Rate

The Radeon RX 570 should be a lot (approximately 216%) better at texture filtering than the GeForce GTS 150. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 102144 (216%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 570 is superior to the GeForce GTS 150, and very much so. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 25536 (216%)

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 transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
