Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

RTX A4000 has 1659% better value for money than UHD Graphics 620.

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.

Form factor & compatibility

Information on UHD Graphics 620 and RTX A4000 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 x1	PCIe 4.0 x16
Length	no data	241 mm
Width	no data	1-slot
Supplementary power connectors	no data	1x 6-pin

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	LPDDR3/DDR4	GDDR6
Maximum RAM amount	32 GB	16 GB
Memory bus width	System Shared	256 Bit
Memory clock speed	System Shared	14 GB/s
Memory bandwidth	no data	448.0 GB/s
