GeForce 9800 GT 512MB vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should theoretically be quite a bit superior to the GeForce 9800 GT 512MB in general. (explain)

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

Texel Rate

The Radeon R9 M365X is just a bit (about 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 high levels of AA is important to you, then the Radeon R9 M365X is the winner, by a large margin. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 Render Output Units by the clock speed of the card. 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
