GeForce 9800 GT 512MB vs Radeon R9 M365X

Intro

The GeForce 9800 GT 512MB uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the Radeon R9 M365X, which features GPU clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Radeon R9 M365X 72000 MB/sec
GeForce 9800 GT 512MB 57600 MB/sec
Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X is a small bit (approximately 10%) better at anisotropic filtering than the GeForce 9800 GT 512MB. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce 9800 GT 512MB 33600 Mtexels/sec
Difference: 3400 (10%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M365X is a better choice, by far. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce 9800 GT 512MB 9600 Mpixels/sec
Difference: 5200 (54%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
