Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

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.

Pipelines / CUDA cores	384	40
Core clock speed	1024 MHz	800 MHz
Boost clock speed	1024 MHz	no data
Number of transistors	1,550 million	181 million
Manufacturing process technology	28 nm	55 nm
Power consumption (TDP)	50 Watt	30 Watt
Texture fill rate	24.50	3.200
Floating-point performance	784.1 gflops	64 gflops

Form factor & compatibility

Information on Radeon 530 and Radeon HD 3470 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 x8	PCIe 2.0 x16
Length	no data	168 mm
Width	no data	1-slot
Supplementary power connectors	None	None

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	DDR3/GDDR5	GDDR3
Maximum RAM amount	4 GB	256 MB
Memory bus width	64 Bit	64 Bit
Memory clock speed	2250 MHz	1900 MHz
