GeForce 9800 GX2 vs Radeon R9 M370X

Intro

The GeForce 9800 GX2 uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a speed of 1000 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare that to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce 9800 GX2 128000 MB/sec
Radeon R9 M370X 72000 MB/sec
Difference: 56000 (78%)

Texel Rate

The GeForce 9800 GX2 will be much (about 140%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon R9 M370X 32000 Mtexels/sec
Difference: 44800 (140%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 9800 GX2 is the winner, by a large margin. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
Radeon R9 M370X 12800 Mpixels/sec
Difference: 6400 (50%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
