GeForce 9800 GT 1GB vs GeForce GTS 450 1GB

Intro

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

Compare that to the GeForce GTS 450 1GB, which uses a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 memory is set to run at a frequency of 902 MHz on this particular card. It features 192 SPUs along with 32 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability 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.
