GeForce 9800 GTX+ vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core speed at 575 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 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M265X should theoretically be a small bit faster than the GeForce 9800 GTX+ in general. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX+ should be much (approximately 105%) more effective at texture filtering than the Radeon R9 M265X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 24232 (105%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 9800 GTX+ is a better choice, and very much so. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 2608 (28%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
