GeForce GTS 450 vs GeForce GTX 650

Intro

The GeForce GTS 450 makes use of a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 memory works at a frequency of 902 MHz on this card. It features 192 SPUs as well as 32 TAUs and 16 ROPs.

Compare all of that to the GeForce GTX 650, which has a GPU core clock speed of 1058 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

Best Single Slot Video Card? - Hardware Canucks says:

[...] 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 :/ [...]
