GeForce 9800 GTX vs Radeon R9 M365X

Intro

The GeForce 9800 GTX features a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

GeForce 9800 GTX 43200 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 6200 (17%)

Pixel Rate

The Radeon R9 M365X will be much (approximately 37%) faster with regards to AA than the GeForce 9800 GTX, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 4000 (37%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
