VS

GeForce GT 430 (OEM) vs Radeon HD 4650 1GB

Intro

The GeForce GT 430 (OEM) has a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Compare those specs to the Radeon HD 4650 1GB, which uses a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR3 memory runs at a speed of 700 MHz on this model. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
