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 is set to run at a speed of 902 MHz on this particular card. It features 192 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this model. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max 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 :/ [...]
