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	576	512
Core clock speed	824 MHz	no data
Boost clock speed	no data	1750 MHz
Number of transistors	2,540 million	no data
Manufacturing process technology	28 nm	10 nm
Power consumption (TDP)	65 Watt	65 Watt
Texture fill rate	39.55	56.00
Floating-point performance	949.2 gflops	no data

Size and compatibility

Information on GeForce GTX 645 OEM and Arc Graphics 64EU Mobile 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). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

Interface	PCIe 3.0 x16	Ring Bus
Length	147 mm	no data
Width	1-slot	no data
Supplementary power connectors	None	no data

Memory

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	System Shared
Maximum RAM amount	1 GB	System Shared
Memory bus width	128 Bit	System Shared
Memory clock speed	4000 MHz	System Shared
Memory bandwidth	64 GB/s	no data

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	1x DVI, 1x HDMI, 1x DisplayPort	Portable Device Dependent
HDMI	+	no data
