GeForce 830M vs Radeon HD 5450

Intro

The GeForce 830M features a core clock speed of 1029 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It features 256 SPUs, 16 TAUs, and 8 ROPs.

Compare all of that to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 RAM works at a speed of 800 MHz on this particular card. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450 19 Watts
GeForce 830M 25 Watts
Difference: 6 Watts (32%)

Memory Bandwidth

The GeForce 830M, in theory, should be a small bit faster than the Radeon HD 5450 in general. (explain)

GeForce 830M 14400 MB/sec
Radeon HD 5450 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 830M will be a lot (more or less 217%) better at anisotropic filtering than the Radeon HD 5450. (explain)

GeForce 830M 16464 Mtexels/sec
Radeon HD 5450 5200 Mtexels/sec
Difference: 11264 (217%)

Pixel Rate

The GeForce 830M should be quite a bit (more or less 217%) more effective at anti-aliasing than the Radeon HD 5450, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce 830M 8232 Mpixels/sec
Radeon HD 5450 2600 Mpixels/sec
Difference: 5632 (217%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
