Technical specs

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.

Pipelines / CUDA cores	no data	120
Core clock speed	400 MHz	600 MHz
Number of transistors	302 million	390 million
Manufacturing process technology	110 nm	65 nm
Thermal design power (TDP)	65 Watt	35 Watt
Texture fill rate	8.000	4.800
Floating-point performance	no data	144 gflops

Compatibility, dimensions and requirements

Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).

Interface	PCIe 1.0 x16	PCIe 1.0 x16
Length	226 mm	no data
Width	1-slot	1-slot
Supplementary power connectors	1x 6-pin	None

Memory

Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM.

Memory type	GDDR3	DDR2
Maximum RAM amount	256 MB	512 MB
Memory bus width	256 Bit	128 Bit
Memory clock speed	1000 MHz	1000 MHz
Memory bandwidth	32 GB/s	16 GB/s

Video outputs and ports

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.

Display Connectors
