There are a few RX 470 cards with 8GB of VRAM but that is overkill. 4GB is adequate for 1920×1080 gaming.

Fans used in the SAPPHIRE NITRO + Radeon RX 470 video cards support Quick Connect. This means that they can be easily removed, cleaned and replaced, since they are securely fixed with just one screw and you will not need to disassemble the casing or other elements of the video card.

Double ball bearings in the design of the fans ensure their smooth start-up, long service life and protect against dust. The bearing design in combination with the efficient shape of the fan blades ensures quiet operation of the cooling system.

In the new generation of video cards, we have implemented a system for quickly checking the state of the cooling system. Fan Check allows you to monitor the status of the fans using the SAPPHIRE TriXX 3.0 utility and immediately contact support service in the event of problems.

High dynamic range support (High Dynamic Range, HDR) is a real find for gamers and moviegoers who truly appreciate image quality. This technology allows you to increase the range of hues and contrast on compatible displays. HDR games look amazingly bright and sharp compared to even the highest quality SDR content.

The card  as pictured has one DVI-D port but HDMI adapters are very inexpensive. We only intend to use 1 LCD panel with the card, so having one port is not a major problem. This card could also be positioned as a slave card in a CFX setup.

The card is UEFI so it can be used with a secure boot setup if desired. UEFI has been standard now since Windows 8 has been delivered some 8 years ago.

The VCX 11256-28-21G is close to 5 GFLOPS in turbo mode which will perk up games nicely. We are concerned that the card will be a tight squeeze to install in our Acer E700 machine, NewEgg has the card at 9 inches long. We have 850W power supplies so we have all demands covered.

While the Radeon cards are behind nVidia in market share, the RX 470 is priced below the inferior GTX 1050 and GTX 1050 Ti cards which occupy the  US $99 to $129 segment. In effect the RX 470 is over double the performance for less money which works for us.

GAMING AT 1920X1080

Now with the RX 470 and a 1920×1080 LCD, no game will be unplayable for many years to come. The 5 TFLOPS of the card is so extreme that games can be cranked up. We use a DVI to HDMI dongle to support an IPS LCD so this card can be leveraged to its best advantage.
