Value for money

Performance to price ratio. The higher, the better.

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	8704	7
Core clock speed	1450 MHz	3 MHz
Boost clock speed	1710 MHz	400 MHz
Number of transistors	28,300 million	75 million
Manufacturing process technology	8 nm	110 nm
Power consumption (TDP)	320 Watt	no data
Texture fill rate	465.1	1.600

Size and compatibility

Information on GeForce RTX 3080 and GeForce Go 6400 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 4.0 x16	PCIe 1.0 x16
Length	285 mm	no data
Width	2-slot	no data
Supplementary power connectors	1x 12-pin	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	GDDR6X	DDR
Maximum RAM amount	10 GB	32 MB
Memory bus width	320 Bit	64 Bit
Memory clock speed	19000 MHz	700 MHz
Memory bandwidth	760.3 GB/s	5.6 GB/s
Shared memory	-	-

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 HDMI, 3x DisplayPort	No outputs
HDMI	+	no data
