GeForce GTS 450 vs GeForce GTX 650
Intro
The GeForce GTS 450 comes with a clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 16 ROPs.Compare those specs to the GeForce GTX 650, which features core speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to 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 :/ [...]
