A Question

Compare any two graphics cards:
VS

GeForce GTX 295 vs GeForce GTX Titan

Intro

The GeForce GTX 295 comes with a GPU core speed of 576 MHz, and the 896 MB of GDDR3 RAM is set to run at 999 MHz through a 448-bit bus. It also features 240 Stream Processors, 80 TAUs, and 28 Raster Operation Units.

Compare those specs to the GeForce GTX Titan, which uses a 28 nm design. nVidia has set the core frequency at 837 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this card. It features 2688 SPUs along with 224 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX Titan 250 Watts
GeForce GTX 295 289 Watts
Difference: 39 Watts (16%)

Memory Bandwidth

In theory, the GeForce GTX Titan is 29% faster than the GeForce GTX 295 in general, because of its higher bandwidth. (explain)

GeForce GTX Titan 288384 MB/sec
GeForce GTX 295 223776 MB/sec
Difference: 64608 (29%)

Texel Rate

The GeForce GTX Titan is a lot (more or less 103%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)

GeForce GTX Titan 187488 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 95328 (103%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan is superior to the GeForce GTX 295, by a large margin. (explain)

GeForce GTX Titan 40176 Mpixels/sec
GeForce GTX 295 32256 Mpixels/sec
Difference: 7920 (25%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
