Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

GTX 560 Ti has 2175% better value for money than GTX 660 OEM.

Detailed specifications

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Width	2-slot	2-slot
Supplementary power connectors	1x 6-pin	2x 6-pin

VRAM capacity and type

Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.

Memory type	GDDR5	GDDR5
Maximum RAM amount	2 GB	1 GB
Memory bus width	256 Bit	256 Bit
Memory clock speed	5600 MHz	2004 MHz
Memory bandwidth	179.2 GB/s	128.3 GB/s

Connectivity and outputs

Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
