GeForce GTS 450 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 memory works at a frequency of 900 MHz on this specific model. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTS 450 should be 301% quicker than the Radeon R5 M330 in general, because of its higher data rate. (explain)

GeForce GTS 450		57728 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 43328 (301%)

Texel Rate

The GeForce GTS 450 should be much (about 22%) better at texture filtering than the Radeon R5 M330. (explain)

GeForce GTS 450		25056 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 4456 (22%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTS 450 is the winner, and very much so. (explain)

GeForce GTS 450		12528 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 4288 (52%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
