GeForce GTS 450 vs GeForce GTX 650
Intro
The GeForce GTS 450 has a clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare those specifications to the GeForce GTX 650, which features GPU core speed of 1058 MHz, and 1024 MB of GDDR5 RAM set to run at 1250 MHz through a 128-bit bus. It also is made up of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 reach the max 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 :/ [...]
