Value for money

Performance to price ratio. The higher, the better.

GTX 1660 has 1650% better value for money than Tesla K20c.

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	2496	1408
Core clock speed	706 MHz	1530 MHz
Boost clock speed	no data	1785 MHz
Number of transistors	7,080 million	6,600 million
Manufacturing process technology	28 nm	12 nm
Power consumption (TDP)	225 Watt	120 Watt
Texture fill rate	146.8	157.1
Floating-point performance	3,524 gflops	no data

Size and compatibility

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

Interface	PCIe 2.0 x16	PCIe 3.0 x16
Length	267 mm	229 mm
Width	2-slot	2-slot
Supplementary power connectors	1x 6-pin + 1x 8-pin	1x 8-pin

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	GDDR5
Maximum RAM amount	5 GB	6 GB
Memory bus width	320 Bit	192 Bit
Memory clock speed	5200 MHz	8000 MHz
Memory bandwidth	208.0 GB/s	192.1 GB/s
Shared memory	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	No outputs	1x DVI, 1x HDMI, 1x DisplayPort
HDMI	no data	+
