GeForce GTS 250 1GB vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTS 250 1GB is 389% quicker than the Radeon R5 M330 overall, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTS 250 1GB should be a lot (more or less 129%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

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

Pixel Rate

The GeForce GTS 250 1GB should be a lot (about 43%) better at AA than the Radeon R5 M330, and should be capable of handling higher resolutions better. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
