GeForce GTX 260 vs GeForce GTX 650
Intro
The GeForce GTX 260 comes with a GPU core 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 Stream Processors, 64 TAUs, and 28 Raster Operation Units.Compare all that to the GeForce GTX 650, which makes use of a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 memory works at a speed of 1250 MHz on this specific model. It features 384 SPUs along with 32 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better 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 amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability 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.
