VS

GeForce 930M vs Radeon HD 4650 512MB

Intro

The GeForce 930M features a GPU core speed of 928 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Compare those specifications to the Radeon HD 4650 512MB, which has GPU clock speed of 600 MHz, and 512 MB of DDR2 memory running at 500 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 4650 512MB should in theory perform a little bit faster than the GeForce 930M overall. (explain)

Radeon HD 4650 512MB 16000 MB/sec
GeForce 930M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 930M is a bit (about 16%) more effective at texture filtering than the Radeon HD 4650 512MB. (explain)

GeForce 930M 22272 Mtexels/sec
Radeon HD 4650 512MB 19200 Mtexels/sec
Difference: 3072 (16%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 930M is the winner, and very much so. (explain)

GeForce 930M 7424 Mpixels/sec
Radeon HD 4650 512MB 4800 Mpixels/sec
Difference: 2624 (55%)

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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
