GeForce GTS 250 512MB vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTS 250 512MB should in theory be a lot better than the Radeon R5 M330 in general. (explain)

GeForce GTS 250 512MB		70400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 56000 (389%)

Texel Rate

The GeForce GTS 250 512MB should be quite a bit (more or less 129%) faster with regards to texture filtering than the Radeon R5 M330. (explain)

GeForce GTS 250 512MB		47232 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 26632 (129%)

Pixel Rate

The GeForce GTS 250 512MB should be quite a bit (more or less 43%) more effective at full screen anti-aliasing than the Radeon R5 M330, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTS 250 512MB		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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
