GeForce GTS 450 vs GeForce GTX 650
Intro
The GeForce GTS 450 comes with a core clock speed of 783 MHz and a GDDR5 memory frequency 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.Compare all of that to the GeForce GTX 650, which features GPU core speed of 1058 MHz, and 1024 MB of GDDR5 RAM running at 1250 MHz through a 128-bit bus. It also features 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

One Response to “GeForce GTS 450 vs GeForce GTX 650”[...] GeForce GTS 450 vs GeForce GTX 650 – Performance Comparison Benchmarks @ Hardware Compare Or a 640 would be very close to the performance of a GTS 450 i think! those cards are around 100$ and 80$... I would really recommend a 650 or a 640,new technology! and they are small. You are right,the 6750 is about the same performance...But well it's not a super new card :/ [...]
