ASUS RX 5700 TUF Gaming X3 OC Edition Review

Rating: 6.5.

Since AMD launched its new Navi graphics cards back in July, a lot of focus has been given to the RX 5700 XT, with the baby brother RX 5700 receiving less attention. We are trying to change that today, however, with a look at ASUS’ TUF Gaming X3 RX 5700 card. Featuring a smart black shroud, triple-fan cooler and factory overclocked core, is this the card to go for under £400?

As part of the ASUS TUF Gaming series, the company has made a few claims regarding the ‘tuf’ nature of this new RX 5700. These include an 144-hour validation program, Auto-Extreme Technology which ‘uses automation to enhance reliability’, and even ‘space-grade lubricant‘ for the dual ball bearing fans.

Pricing is also something to be aware of, with this card coming in at £379.99. That’s £50 above the reference MSRP for RX 5700, putting close to RX 5700 XT territory.

ASUS has also pushed the clock speed of the RX 5700 a little further, with a rated ‘game clock’ of 1720MHz, which is 95MHz faster than the reference card. There is the option to download ASUS GPU Tweak II and enable an ‘OC mode’, but this only adds an extra 5MHz to the game clock and is an extra step required from the end-user.

Elsewhere, core spec of the RX 5700 means we have 36 Compute Units (CUs), with each CU housing 64 Stream Processors for a total of 2304. There’s also 8GB of GDDR6 memory, clocked at 14Gbps, operating across a 256-bit bus, for 448GB/s total memory bandwidth.
