GeForce 9400 GT 256MB vs Radeon R5 M330

Intro

The GeForce 9400 GT 256MB features a GPU clock speed of 550 MHz, and the 256 MB of GDDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Compare all that to the Radeon R5 M330, which comes with GPU core speed of 1030 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

GeForce 9400 GT 256MB 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be quite a bit (more or less 368%) more effective 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

The Radeon R5 M330 is quite a bit (more or less 275%) more effective at FSAA than the GeForce 9400 GT 256MB, and able to handle higher screen resolutions while still performing well. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
