GeForce 930M vs Radeon HD 4650 512MB

Intro

The GeForce 930M comes with core speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Compare those specs to the Radeon HD 4650 512MB, which has a clock frequency of 600 MHz and a DDR2 memory speed of 500 MHz. It also uses a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 4650 512MB should be 11% faster than the GeForce 930M in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce 930M should be a small bit (approximately 16%) faster with regards to anisotropic 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 screen 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: 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's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
