GeForce GTX 260 vs GeForce GTX 650
Intro
The GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this specific model. It features 192 SPUs as well as 64 Texture Address Units and 28 ROPs.Compare those specifications to the GeForce GTX 650, which has a clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum 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.
