Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

RX 550 and HD Graphics 400 have a nearly equal value for money.

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	512	96
Core clock speed	1100 MHz	320 MHz
Boost clock speed	1183 MHz	640 MHz
Number of transistors	2,200 million	189 million
Manufacturing process technology	14 nm	14 nm
Power consumption (TDP)	50 Watt	6 Watt
Texture fill rate	37.86	7.680
Floating-point performance	1,211 gflops	134.4 gflops

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 x8	PCIe 3.0 x1
Length	145 mm	no data
Width	2-slot	IGP
Supplementary power connectors	None	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	GDDR5	DDR3L
Maximum RAM amount	4 GB	8 GB
Memory bus width	128 Bit	System Shared
Memory clock speed	7000 MHz	System Shared
Memory bandwidth	112.0 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.
