GeForce GT 310 vs Radeon HD 5450
Intro
The GeForce GT 310 comes with a GPU core clock speed of 589 MHz, and the 512 MB of DDR2 RAM runs at 1000 MHz through a 64-bit bus. It also is made up of 16 Stream Processors, 8 Texture Address Units, and 4 ROPs.Compare those specifications to the Radeon HD 5450, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 memory runs at a frequency of 800 MHz on this particular card. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock 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 applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.

Comments
One Response to “GeForce GT 310 vs Radeon HD 5450”Ive got both 5450 and g310 altough the 5450 is a stronger card ati software is more problematic then nvidia and for that and many other reasons i would recomend the geforce g310 and any other nvidia gpu its only a opionion witch many people seem to have so.
