Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 7750
IntroThe GeForce GTS 450 1GB features a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 memory runs at 902 MHz through a 128-bit bus. It also is comprised of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon HD 7750, which comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7750 should theoretically be much better than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe Radeon HD 7750 is just a bit (about 2%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7750 is superior to the GeForce GTS 450 1GB, but it probably won't make a huge difference. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure 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 processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

One Response to “GeForce GTS 450 1GB vs Radeon HD 7750”Beti ya.. kalo gts 450 kykny gak worth deh.. Coz hd 7750 lebih murah, lebih powerfull dan lebih hemat daya. 5 jempol dah buat 7750...tapi ya itu ATi nggak punya CUDA + physX...
