GeForce 9800 GT 1GB vs GeForce GTS 450 1GB

Intro

The GeForce 9800 GT 1GB has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It is made up of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

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

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to 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.
