GeForce 9800 GT 1GB vs Radeon HD 3850 X2

Intro

The GeForce 9800 GT 1GB makes use of a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 3850 X2, which makes use of a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 RAM works at a speed of 828 MHz on this particular model. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3850 X2, in theory, should perform quite a bit faster than the GeForce 9800 GT 1GB overall. (explain)

Radeon HD 3850 X2 105984 MB/sec
GeForce 9800 GT 1GB 57600 MB/sec
Difference: 48384 (84%)

Texel Rate

The GeForce 9800 GT 1GB is much (more or less 57%) more effective at texture filtering than the Radeon HD 3850 X2. (explain)

GeForce 9800 GT 1GB 33600 Mtexels/sec
Radeon HD 3850 X2 21376 Mtexels/sec
Difference: 12224 (57%)

Pixel Rate

The Radeon HD 3850 X2 should be a lot (approximately 123%) faster with regards to FSAA than the GeForce 9800 GT 1GB, and able to handle higher screen resolutions more effectively. (explain)

Radeon HD 3850 X2 21376 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 11776 (123%)

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 megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
