GeForce GT 340 1GB vs Radeon HD 3850 X2

Intro

The GeForce GT 340 1GB features a GPU core speed of 550 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 TAUs, and 8 ROPs.

Compare all of that to the Radeon HD 3850 X2, which makes use of a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 RAM runs at a frequency of 828 MHz on this model. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3850 X2 will be 95% faster than the GeForce GT 340 1GB in general, due to its higher bandwidth. (explain)

Radeon HD 3850 X2 105984 MB/sec
GeForce GT 340 1GB 54400 MB/sec
Difference: 51584 (95%)

Texel Rate

The Radeon HD 3850 X2 is much (about 21%) better at anisotropic filtering than the GeForce GT 340 1GB. (explain)

Radeon HD 3850 X2 21376 Mtexels/sec
GeForce GT 340 1GB 17600 Mtexels/sec
Difference: 3776 (21%)

Pixel Rate

The Radeon HD 3850 X2 will be a lot (about 386%) better at AA than the GeForce GT 340 1GB, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 3850 X2 21376 Mpixels/sec
GeForce GT 340 1GB 4400 Mpixels/sec
Difference: 16976 (386%)

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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
