GeForce GTS 450 1GB vs Radeon R9 M370X

Intro

Compare 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 memory runs at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X is 25% quicker than the GeForce GTS 450 1GB overall, because of its higher data rate. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 14272 (25%)

Texel Rate

The Radeon R9 M370X will be quite a bit (approximately 28%) better at anisotropic filtering than the GeForce GTS 450 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 6944 (28%)

Pixel Rate

The Radeon R9 M370X should be a little bit (about 2%) more effective at full screen anti-aliasing than the GeForce GTS 450 1GB, and should be capable of handling higher resolutions better. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 272 (2%)

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 max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
