GeForce GTS 450 vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which comes with a core clock frequency of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTS 450		57728 MB/sec
	Difference: 14272 (25%)

Texel Rate

The Radeon R9 M365X is quite a bit (approximately 48%) better at AF than the GeForce GTS 450. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 11944 (48%)

Pixel Rate

The Radeon R9 M365X will be a small bit (approximately 18%) more effective at full screen anti-aliasing than the GeForce GTS 450, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 2272 (18%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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