GeForce 9400 GT 256MB vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R5 M330 should in theory be a little bit superior to the GeForce 9400 GT 256MB overall. (explain)

Radeon R5 M330		14400 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be a lot (more or less 368%) better at texture filtering than the GeForce 9400 GT 256MB. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 16200 (368%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R5 M330 is the winner, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 6040 (275%)

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 information (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
