Core clock speed	1400 MHz	626 MHz
Boost clock speed	1500 MHz	847 MHz
Number of transistors	12,500 million	2,410 million
Manufacturing process technology	14 nm	28 nm
Power consumption (TDP)	300 Watt	17 Watt
Texture fill rate	384.0	10.02
Floating-point performance	12,288 gflops	no data

Form factor & compatibility

Information on Radeon Instinct MI25 and Radeon R5 Mobile Graphics 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	IGP
Length	267 mm	no data
Width	2-slot	no data
Supplementary power connectors	2x 8-pin	no data

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	HBM2	System Shared
Maximum RAM amount	16 GB	System Shared
Memory bus width	2048 Bit	System Shared
Memory clock speed	1704 MHz	System Shared
Memory bandwidth	436.2 GB/s	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

No outputs
