GeForce 9800 GX2 vs Radeon R9 M290X

Intro

The GeForce 9800 GX2 features core clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M290X, which uses a 28 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this specific card. It features 1280 SPUs along with 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 is 20% quicker than the GeForce 9800 GX2 in general, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GX2 should be just a bit (about 13%) faster with regards to texture filtering than the Radeon R9 M290X. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M290X is the winner, and very much so. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 applied 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 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 maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
