GeForce GT 340 1GB vs GeForce GTX 960

Intro

Compare that to the GeForce GTX 960, which makes use of a 28 nm design. nVidia has set the core frequency at 1127 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Memory Bandwidth

In theory, the GeForce GTX 960 should be quite a bit faster than the GeForce GT 340 1GB in general. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 57600 (106%)

Texel Rate

The GeForce GTX 960 is a lot (more or less 310%) more effective at texture filtering than the GeForce GT 340 1GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 54528 (310%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 960 is a better choice, by far. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 31664 (720%)

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 maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses 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 are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
