GeForce GTS 250 512MB vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should perform a little bit faster than the GeForce GTS 250 512MB overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GTS 250 512MB		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce GTS 250 512MB should be much (approximately 28%) better at AF than the Radeon R9 M365X. (explain)

GeForce GTS 250 512MB		47232 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 10232 (28%)

Pixel Rate

The Radeon R9 M365X should be a lot (more or less 25%) more effective at FSAA than the GeForce GTS 250 512MB, and will be capable of handling higher screen resolutions better. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GTS 250 512MB		11808 Mpixels/sec
	Difference: 2992 (25%)

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 over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
