GeForce 9800 GT 1GB vs GeForce GTS 450 1GB

Intro

The GeForce 9800 GT 1GB features a GPU core clock speed of 600 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also features 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

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

GeForce GTS 450 1GB 25056 Mtexels/sec
Difference: 8544 (34%)

Pixel Rate

The GeForce GTS 450 1GB will be quite a bit (more or less 31%) better at AA than the GeForce 9800 GT 1GB, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTS 450 1GB 12528 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 2928 (31%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

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.
