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	3840	40
Core clock speed	1400 MHz	500 MHz
Boost clock speed	1750 MHz	no data
Number of transistors	13,230 million	181 million
Manufacturing process technology	7 nm	55 nm
Power consumption (TDP)	295 Watt	25 Watt
Texture fill rate	420.0	2.376
Floating-point performance	no data	47.52 gflops

Size and compatibility

Information on Radeon VII and Radeon HD 4250 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	PCIe 2.0 x16
Length	305 mm	no data
Width	2-slot	no data
Supplementary power connectors	2x 8-pin	None

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	HBM2	DDR2
Maximum RAM amount	16 GB	512 MB
Memory bus width	4096 Bit	64 Bit
Memory clock speed	1000 MHz	792 MHz

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	1x DVI, 1x VGA, 1x S-Video
HDMI	+	no data
