GeForce GTX 295 vs Geforce GTX 770

Intro

Compare all that to the Geforce GTX 770, which features a clock speed of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It features 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 770		230 Watts
GeForce GTX 295		289 Watts
	Difference: 59 Watts (26%)

Memory Bandwidth

The Geforce GTX 770 should theoretically perform a small bit faster than the GeForce GTX 295 overall. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 608 (0%)

Texel Rate

The Geforce GTX 770 should be quite a bit (approximately 45%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 41728 (45%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 770 is superior to the GeForce GTX 295, but not by far. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 1216 (4%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
