Tiger Lake Discussion Thread

It’s hard to get the full view of how Tiger Lake will perform in OEM laptops. After all, our preview had some conditions attached to it that limited the scope of our testing, and we’ve yet to see the final designs that people will actually be able to buy.

But we do, however, see an idea of how things will be. Tiger Lake’s 10nm SuperFin technology appears to be competitive with AMD’s top-end Ryzen 7 4800U at 15W, and, at 28W and with Dynamic Tuning, even better, at least when it comes to single-core workloads. With multi-core workloads, AMD still has the advantage on its top-end part, with double the cores and threads.

With the i7-1185 G7, Intel has finally caught up in boost speed to its 14nm process node on Comet Lake-U, but only at the 28W setting. It will be interesting to see how OEMs configure the chip to get the most performance out of it, and what that means for battery life, especially if Intel promises similar performance on battery to when it’s plugged in.

There’s still support for AVX-512, which should allow increases in performance in programs coded to take advantage of the instructions.

But the big addition is Iris Xe graphics, which, on the reference system, got us to 1080p at 30 fps in low settings on most tests. We’ll see what comes when laptop manufacturers drop their systems. Still, we’re getting closer to the point where you could reasonably squeeze in a short gaming session on an ultrathin notebook at the expense of fidelity.

Mobile chips always come as part of laptops, though, so if you’re looking for the final verdict, you’ll have to wait for the first Tiger Lake systems to hit our labs this fall.

When Intel unveiled Tiger Lake last month, the company promised a chip that delivered uncompromising performance on both CPU and GPU. Today, it’s clear they weren’t kidding. Intel’s Tiger Lake is proof that the company still knows how to build performant CPUs.

Incidentally, it’s also the best APU — though of course, Intel doesn’t use that term — anyone has ever shipped. That’s according to the extensive data published by our sister site PCMag. While I haven’t tested the system myself, I trust the work they’ve done to be accurate.

Over the past 12 months, Intel and AMD have engaged a rapid-fire series of mobile chips. First, Intel launched Ice Lake, with better GPU performance and higher efficiency, but relatively flat CPU performance compared with 14nm CPUs. Then, AMD countered with its Ryzen 4000 mobile processors. These chips gave AMD a decisive lead in the mobile industry for the first time in years, and they’ll remain excellent CPUs after Tiger Lake is widely available, but Intel has decisively reclaimed per-core leadership in CPU performance as well as overall GPU performance leadership.

Are there workloads where AMD retains an advantage? Absolutely. The eight Ryzen CPU cores are quite powerful in absolute terms and rendering benchmarks like Cinebench as well as encoding tests like Handbrake both shine on Ryzen. Anywhere AMD can leverage its core count, it performs well. In multiple applications like the Adobe suites, Tiger Lake is faster than Renoir.

Interestingly, Tiger Lake’s 15W configuration often outperforms AMD’s 25W configuration, according to PCMag’s testing. With Ice Lake, Intel could only cleanly beat its 15W systems with 25W hardware. That’s not the case any longer; Tiger Lake 15W systems outperform Ice Lake 25W configurations. Any way you slice it, TGL is an impressive outing for Intel.

AMD will debut its Zen 3 architecture for desktops before too much longer, so we’ll get a chance to see what the platform offers in that venue — and likely some idea of what to expect from the eventual APUs as well. Both Nvidia and Intel have come out swinging this fall. It’s going to be an interesting year, as AMD responds to its primary opponents in both markets.
