PCWorld – August 2019

AUGUST 2019 PCWorld 61

upgraded to GDDR6 memory. Heck, AMD
even managed to tame their blower-style
cooler design, learning from the mistakes of
the frankly unpleasant-to-be-around Vega 64.
Nvidia tried to spoil their launch with the
surprise release of the excellent GeForce
RTX 2060 Super and RTX 2070 Super (see
page 43), but some aggressive pre-launch
price cuts (go.pcworld.com/cuts) by AMD
foiled that plan. The $350 Radeon RX 5700
and $400 Radeon RX 5700 XT are great
graphics cards, full stop.

SPECS AND FEATURES

Warning: With so much new technology

baked into the Radeon RX 5700 series, this is

going to be a long review. We’re going to

kick it off by talking about what’s fresh under

the hood. Got it? Good. On to the cool stuff.

Let’s examine the hardware, before

delving into new software features later.

Here’s an AMD-supplied list of technological

specifications for the Radeon RX 5700 and

Radeon RX 5700 XT, alongside the same stats

for the Radeon RX Vega GPUs they’re
