REVIEWS PREVIEW: INTEL 11TH-GEN CORE I7-1185G7 TIGER LAKE

entertain playing slightly older AAA games on

a laptop with Intel integrated graphics is

unheard of. Crank down the resolution and

tune some game settings, and we think Xe

could be as revolutionary in laptop gaming

as, well, AMD’s Ryzen chip was.

Although the OpenCL graphics engine

seems to be rapidly losing steam, we did want

to see where the Xe falls, so we used LuxMark

3.1 and LuxBall. It’s again very impressive,

with Iris Xe about 225 percent faster than Intel

HD graphics, 84 percent faster than Iris Plus

and 143 percent faster than Radeon.

The last graphics-focused test we wanted

to run was the free HandBrake utility, using the

CPU’s Quick Sync engine. Intel said the results

wouldn’t currently represent what Tiger Lake

can do. We suspect that means Tiger Lake

would lose, as we’ve tested AMD’s VCE

against Ice Lake’s Quick Sync performance

and Ryzen was slightly faster (go.pcworld.

com/r4bn). Still, there’s not much of a point

right now.

We’ll close out with one advanced media

engine test: Microsoft’s free Video Editor

built into Windows 10, which leverages both

Quick Sync and VCE. We had previously

tried to use it when Ryzen first came out, but

the hardware acceleration didn’t work on

AMD CPUs. AMD has since worked with

Microsoft to fix it. For this simple test, we

take the Tears of Steel 4K video, throw on a

sepia filter, and export it to 1080p with

hardware acceleration enabled.

While all the chips are decently fast,

Ryzen actually finishes last, even losing to

the 10th-gen Comet Lake U chip. 11th-gen

Tiger Lake itself comes in second place,

with the 10th-gen Ice Lake crossing the

finish line first.
