GeForce GTS 250 1GB vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Radeon R9 M370X		32000 Mtexels/sec
	Difference: 15232 (48%)

Pixel Rate

The Radeon R9 M370X should be a bit (more or less 8%) better at FSAA than the GeForce GTS 250 1GB, and able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GTS 250 1GB		11808 Mpixels/sec
	Difference: 992 (8%)

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 maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
