GeForce 9800 GX2 vs Radeon R9 M290X

Intro

The GeForce 9800 GX2 features a GPU core speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M290X, which features core speeds of 850 MHz on the GPU, and 1200 MHz on the 4096 MB of GDDR5 memory. It features 1280 SPUs as well as 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M290X 100 Watts
GeForce 9800 GX2 197 Watts
Difference: 97 Watts (97%)

Memory Bandwidth

In theory, the Radeon R9 M290X will be 20% faster than the GeForce 9800 GX2 in general, due to its greater data rate. (explain)

Radeon R9 M290X 153600 MB/sec
GeForce 9800 GX2 128000 MB/sec
Difference: 25600 (20%)

Texel Rate

The GeForce 9800 GX2 will be just a bit (approximately 13%) better at AF than the Radeon R9 M290X. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon R9 M290X 68000 Mtexels/sec
Difference: 8800 (13%)

Pixel Rate

The Radeon R9 M290X should be a lot (more or less 42%) better at FSAA than the GeForce 9800 GX2, and should be capable of handling higher resolutions more effectively. (explain)

Radeon R9 M290X 27200 Mpixels/sec
GeForce 9800 GX2 19200 Mpixels/sec
Difference: 8000 (42%)

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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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.
