GeForce GTX 260 vs GeForce GTX 650
Intro
The GeForce GTX 260 has a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is comprised of 192 SPUs, 64 TAUs, and 28 ROPs.Compare those specs to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core speed at 1058 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this specific card. It features 384 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher 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 maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 potential to get to the max fill rate.

4 Responses to “GeForce GTX 260 vs GeForce GTX 650”The GTX 260 is essentially the same as GTX 650, the advantage the GTX 650 has is Directx 11
Looking at the gtx 650's power consumption, this has to be a very effective card for casual gaming deliviering 260's performance. (+directx 11.1)
lol 650 for lyfe!
Pros e cons of the two cards:
GTX 260:
- It is faster in general.
- A lot more Cheaper than the GTX 650 (You can save more than 60$).
GTX 650
- DirectX 11.
- Less Power Consuption.
It's not a real comparison, just because the GTX 260 is pretty old... But it's still a good graphic card.
