Compare any two graphics cards:
GeForce GT 430 vs GeForce GTS 450
IntroThe GeForce GT 430 features a GPU core clock speed of 700 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.Compare those specs to the GeForce GTS 450, which has a core clock frequency of 783 MHz and a GDDR5 memory speed of 902 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 192 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 should perform a lot faster than the GeForce GT 430 in general. (explain)
Texel RateThe GeForce GTS 450 will be a lot (approximately 124%) better at texture filtering than the GeForce GT 430. (explain)
Pixel RateThe GeForce GTS 450 should be a lot (approximately 347%) more effective at full screen anti-aliasing than the GeForce GT 430, and also should be able to handle higher resolutions without losing too much performance. (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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

One Response to “GeForce GT 430 vs GeForce GTS 450”There's a local store selling these two cards. Now it's no contest which one I'll be buying. The GTS450 is only $10 more too
