Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

Quadro P400 has 68% better value for money than RTX A6000.

Detailed specifications

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.

Power consumption (TDP)	30 Watt	300 Watt
Texture fill rate	20.03	625.0
Floating-point performance	679.9 gflops	no data

Form factor & 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 3.0 x16	PCIe 4.0 x16
Length	145 mm	267 mm
Width	1-slot	2-slot
Supplementary power connectors	None	8-pin EPS

VRAM capacity and type

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	GDDR6
Maximum RAM amount	2 GB	48 GB
Memory bus width	64 Bit	384 Bit
Memory clock speed	4008 MHz	16000 MHz
Memory bandwidth	32.06 GB/s	768.0 GB/s
Shared memory	no data	-

Connectivity and outputs

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

3x mini-DisplayPort

4x DisplayPort
