Xfx Radeon Rx 590 Fatboy Oc+ 8gb Review
Meet the XFX Radeon RX 590 Fatboy 8GB OC+
XFX uses technology from its Radeon RX 580 GTS Black Edition, saving the company from having to rework the Radeon RX 590 Fatboy 8GB OC+.
The new menu weighs in at one.89lb (856g). From the edge of its slot panel to the finish of its fan shroud, we measure x.half-dozen inches (26.8cm). The heat sink associates is 1.vii inches (iv.3cm) deep. However, you have to add together another 0.2in (0.5cm) to business relationship for the backplate. This is a true 2.five-slot card, pregnant it takes upwards three expansion slots on your motherboard. A 4.8-inch (12.2cm) measurement from where the bill of fare sits in a PCIe slot to the libation's pinnacle border is actually pretty tall, dwarfing our Founders Edition GeForce and reference Radeon RX Vega cards.
From the bottom, it'south easy to meet that XFX's heat sink employs aluminum fins oriented horizontally. We approve, since heated air isn't pushed down toward your motherboard and out against a case wall. Rather, some is exhausted out the expansion slot cover.
We likewise catch a glimpse of four heat pipes that sit down flat over a copper plate and dissipate thermal free energy through the sink'due south fins.
Upwardly top, at that place's an eight- and six-pin power connector, cluing united states of america in that a shrink to 12nm doesn't translate to power-savings from Radeon RX 590. Over again, AMD's board power rating is 225W compared to Radeon RX 580's 185W specification.
XFX loads the slot bracket with five display outputs: 3 DisplayPort ane.4-set connectors, HDMI ii.0, and one DVI-D port. Although we appreciate copious connectivity, the DVI output does take upward room that could have been freed upwards for exhaust.
With its heat sink removed, the Radeon RX 590 Fatboy 8GB OC+ looks nearly identical to the Radeon RX 580 GTS Blackness Edition. Again, XFX uses six power phases for the GPU and 1 phase for memory.
There are hardly whatever components on the dorsum side, except for two BIOS chips.
The post-obit table lists the most of import components on XFX's PCB:
| GPU Power Supply | ||
| PWM Controller | IR35217 International Rectifier six+2-Phase | |
VRM6x IR3578 International Rectifier PowIRstage (Loftier-side, Low-side, Schottky diode, driver)

Smoothing1x 470mH coil per 12V supply connection
Libation and Backplate
The hull-shaped backplate fabricated of dark aluminum makes no contact with the board and doesn't play a part in cooling. There are ventilation holes throughout, though, so at to the lowest degree the plate doesn't trap heat underneath. The plate's simply purpose is to expect good.
Because the backplate is screwed in from the PCB's top side, the only way to remove it is disassembling the entire heat sink.
The cooler itself is a elementary thing based on two 8mm and 2 6mm estrus pipes fabricated of copper blended material. The pipes misemploy heat away from AMD'southward Polaris chip and into a fin stack that spans both ends of the PCB. Underneath them is a thin copper plate that contacts the GPU die. A pocket-sized frame surrounds the plate, sandwiching thermal pads betwixt the metal and all viii memory modules.
This small thermal solution is tasked with removing as much as 250W from the board underneath. It'southward more capable than AMD'southward reference Radeon RX 480, only does achieve its limit nether load in a closed chassis.
| Thermal Solution At A Glance | |
| Type of Cooler | Air |
| GPU Estrus Sink | Copper plate on heat pipes |
| Cooling Fins | Aluminum, horizontally-oriented, tight fin pattern |
| Oestrus Pipes | 2x 8mm + 2x 6mm, copper composite |
| VRM Cooling | Via its own heat sink |
| RAM Cooling | Via frame on heat sink |
| Fans | 2x 9.5cm fans, eleven rotor blades each, semi-passive mode |
| Backplate | Aluminum backplate, no cooling function |
