AMD’s Navi GPUs mark the company’s return to the high-performance graphics card market after a multiple-year absence. The Radeon RX 5700 and 5700 XT offer near-RTX 2060 Super and 2070 Super level performance while costing markedly less.
In this post, we compare one of the premier board partner RX 5700 XT models, the Powercolor Radeon RX 5700 XT Red Devil, and see how it stacks up against the reference model and the competing RTX 2070 Super. We have a look at the gaming performance, thermals, overclocking capabilities and the PCB design of the two cards in detail. Let’s dig in:
- CPU: AMD Ryzen 7 3700X
- Motherboard: ASRock Taichi X570
- Memory: Trident Z Royal 16GB @ 3600MHz
- HDD: WD Black 4TB
- PSU: Corsair HX1000i
Reference Radeon RX 5700 XT vs Powercolor Red Devil: Specs
|GPU||Price||Shaders||Base Clock||Boost Clock||Memory Clock||Memory|
|RX 5700 XT||$400||2560||1605 MHz||1755 MHz||1750 MHz||8 GB GDDR6|
|PowerColor RX 5700 |
XT Red Devil
|$439||2560||1770 MHz||1905 MHz||1750 MHz||8 GB GDDR6|
On paper, the Red Devil has a fat advantage in terms of the boost clock. But let’s not forget. The boost clocks in-game depend on a bunch of factors such as temperature, power draw, and voltages. Still, a base clock 165MHz higher than the reference model is impressive.
The price, however, is a concern. Most of the other board-partner models 5700 XTs such as the Sapphire Pulse, XFX Radeon RX 5700 XT and the MSI Evoke cost less than $400 while certain variants like the ASRock Challenger is priced as low as $350. Even if it performs the best, paying almost $100 for the same GPU is a hard pass from us.
1440p Gaming Performance
The Powercolor RX 5700 XT Red Devil is just a few frames ahead of the reference model, bridging the gap between the NVIDIA RTX 2070 Super and the latter. Red Dead Redemption 2 sees the biggest boost with the PowerColor RX 5700 XT Red Devil beating both the Reference 5700 XT as well as the GeForce Super by a sound margin.
Thermals and Overclocking
Even at stock settings, there is a quite notable difference between the two cards. Right off the bat, the in-game core clock for the PowerColor Red Devil is notably higher at 1980MHz while the reference model is limited to 1836MHz. Despite running at a higher clock, the Red Devil ran cooler (albeit by just a few degrees) and quieter. You can turn up the fan speed to improve the thermals at the cost of acoustics, but I would recommend sticking to auto.
Upon overclocking, most titles saw a healthy boost in performance, pretty much erasing the gap between the 5700 XT Red Devil and the RTX 2070 Super, with the former even coming out on top in some games like Deus Ex.
The memory was overclocked by +25MHz which resulted in an effective memory speed of 1850MHz (up from 1750MHz). As for the core, we were able to get a +50 which pushed the in-game clock to 2026MHz. This didn’t have a notable impact on the thermals or fan speed and both remained more or less the same. The reference model started hitting temperatures as high as 110 degrees upon overclocking, so we didn’t bother. That’s way out of my comfort zone. (konahonudivers.com)
PowerColor Radeon RX 5700 XT Red Devil: PCB and Heatsink Analysis
At first sight, the Red Devil clearly has a superior PCB: a 10+2 phase VRM (10-core, 2-mem) while the reference model has a 7+2 phase VRM.
However, upon closer inspection, things change. The reference model is using superior capacitors, also called (SDM type) film capacitors while the PowerColor Red Devil is leveraging the standard electrolytic polymer capacitors. The former is more efficient in distributing power compared to the latter (Read more here).
Furthermore, the reference model appears to be using Samsung’s GDDR6 memory which is again more expensive and reliable than the widespread Micron memory chips.
Turing over the PCB lets you have a closer look at the VRM phases. Turns out the RX 5700 XT Red Devil has a 5+1 phase VRM using doublers to make it into 10+2 phases. While technically that *is* a 10-phase VRM, the reference model is using a 7+2 phase (no doublers here) which is better than the former. So better, capacitors, better VRM, better memory…
Overall, the Reference RX 5700 XT has by far the best board out of all the 5700 XTs. However, courtesy of that blower heatsink that advantage is more or less nullified (unless you decide to stick a water block on it).
Speaking of the heatsinks, while the RX 5700 XT Red Devil is using its signature design, the reference board is once again stuck with its blower-style heatsink. The advantages of the former are quite obvious: more fans and heat pipes result in a quieter and cooler card and the metal built adds to the aesthetics.
