GeForce 9800 GT 1GB vs GeForce GTS 450 1GB

Intro

The GeForce 9800 GT 1GB comes with core clock speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTS 450 1GB, which has a core clock frequency of 783 MHz and a GDDR5 memory speed of 902 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 192 SPUs, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

í think 450gts is butter than 98gt

I think both card are the same,

I've got them both but the 9800gt works better with bf4 framerate between 30 35 f/s

the gts450 has a frame rate 16 till 25 f/s. tested this yesterday. with the gts450 it was stuttering as hell, this i don't have with the 9800gt.
