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	32	80
Core clock speed	550 MHz	650 MHz
Number of transistors	314 million	292 million
Manufacturing process technology	65 nm	40 nm
Thermal design power (TDP)	40 Watt	19 Watt
Texture fill rate	8.800	5.200
Floating-point performance	no data	104 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 2.0 x16	PCI
Length	no data	145 mm
Width	1-slot	1-slot
Supplementary power connectors	None	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	DDR2	DDR2
Maximum RAM amount	512 MB	512 MB
Memory bus width	128 Bit	64 Bit
Memory clock speed	1008 MHz	666 MHz
Memory bandwidth	16.13 GB/s	5.328 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	2x DVI, 1x S-Video	1x DVI, 1x HDMI
HDMI	no data	+

API support

APIs supported, including particular versions of those APIs.

DirectX	11.1 (10_0)	11.2 (11_0)
Shader Model	4.0	5.0
OpenGL	3.3	4.4
OpenCL	1.1	1.2
Vulkan	N/A	N/A
CUDA	1.1	no data
