GeForce GTS 250 1GB vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 RAM works at a frequency of 900 MHz on this specific card. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTS 250 1GB should be 389% faster than the Radeon R5 M330 overall, because of its higher bandwidth. (explain)

GeForce GTS 250 1GB		70400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 56000 (389%)

Texel Rate

The GeForce GTS 250 1GB is quite a bit (more or less 129%) more effective at AF than the Radeon R5 M330. (explain)

GeForce GTS 250 1GB		47232 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 26632 (129%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTS 250 1GB is a better choice, by far. (explain)

GeForce GTS 250 1GB		11808 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 3568 (43%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
