10th Gen Intel Ice Lake vs AMD Ryzen 3000 APUs (Picasso)

Over the last 4-5 years, Intel has been stalling the launch of its 10nm based process node, repeatedly launching rehashes of the 14nm Skylake core. And they got away with it as there was no competition. AMD’s godawful Bulldozer chips and its successors almost drove the company to bankruptcy.

Then came the 1st Gen Ryzen CPUs and everyone got a taste of the new Zen microarchitecture. In a panic, Intel doubled its core counts and increased the core clocks across the boards and in a frenzy ended up the unplanned Core i9 chips. That seemed to be working for a bit but as then 3rd Gen Ryzen lineup dropped earlier this year, Intel’s only advantage: better gaming performance all but dissolved.

Since then team red has been taking over blue territory by leaps and bounds. By now the DIY market is mostly under Ryzen control, and OEMs have also started flocking under the red banner. However, the laptop space is one segment where Intel still holds the crown. Why?

Well, that’s mainly because the 7nm Zen 2 chips are yet to come to the mobility space. According to sources, the Renoir APUs will arrive in the first half of 2020, but for now, we have to be content with Picasso. The Ryzen 3000 APU lineup leveraging the 12nm Zen+ core.

AnandTech has done a comparison of the Surface Book, an AMD Ryzen 7 3780U and the new Ice Lake i7-1065G7 and the results are quite impressive.

The Ice Lake-based i7 basically murders the Ryzen 7. And unlike what we’re used to seeing, Intel continues to lead in the multi-threaded benchmarks as well.

Intel’s advantage continues in Cinebench which is AMD territory, and something Intel doesn’t consider as indicative of real-world performance:

Cinebench R20 - Single-Threaded Benchmark
Cinebench R20 - Multi-Threaded Benchmark

This is something you see…well never. Instead of all that deceptive marketing that Intel has been up to these days, it’d have been better if they just showcased their Ice Lake parts.

AMD Ryzen 7 3780U vs Intel Core i7-1065G7: Gaming Performance

The Ice Lake CPUs feature that Gen 11 iGPU which is supposed to multiple times faster than the preceding Gen 9.5. To give you an idea of what magnitude we’re talking about here, listen to this: 9.5 includes 24EUs but Gen 11 features as many as 64 Execution Units. Earlier, Intel’s integrated graphics used to get crushed by AMD’s Vega grpahics but I suspect that will change here:

Tomb Raider - Value
Rise of the Tomb Raider - Value
Strange Brigade - Value
F1 2017 - Value
F1 2019 - Value
Far Cry 5 - Value

And change the results do. The competition is quite cutthroat, but the Vega GPU manages to win overall. Out of seven titles, the AMD chip marks four wins while the Intel part is restricted to three. Regardless, the results are quite close and I suspect that’ll only continue with Gen12.

Why Isn’t Ice Lake Coming to Desktop?

By now, you’re probably impressed by Intel’s Ice Lake chip and wondering what’s stopping them from launching a desktop-based lineup. The problem is with respect to yields:

In the single-threaded Cinebench test, both the chips struggle to maintain a steady boost clock, but the Ryzen 7 manages to achieve a higher overall frequency. Despite that, the Core i7 draws more power and by the end of the test throttles really hard.

The same thing continues in the multi-threaded test except here it’s even worse. The 10nm Ice Lake i7 is stuck at 3.5GHz while the Ryzen 7 achieves a stable 3.75GHz. And again, the TDP of the Intel part is much worse.

This tells us a lot about the state of Ice Lake: The yields, frequency scaling, and TDP. When a new chip process first hits the market, the yields are low but the frequency and power draw is usually higher than the preceding generation. We saw that with the Ryzen 2000 and the 3000 chips.

With Ice Lake, however, it’s the other way around. The TDPs are higher and the boost clocks are much lower than the Comet Lake parts. Granted, the 14nm node is a lot more mature and the 10nm process is barely out of the bag. But even then the boost clocks are abysmally low. This can only be the result of poor yields which explains why Ice Lake isn’t coming to desktops anytime soon (or ever). It also explains why the 10nm based Ice Lake laptops are so limited in volume.

Conclusion

Intel can still manage a steady hold over the consumer market if it prices the 10th Gen Comet Lake-S CPUs well. After that Rocket Lake is expected to include a backport of the 10nm(++) Willow Cove design. I’m not quite sure if that’ll pan out, and how well the chips will perform, but it ought to be a healthy upgrade over Comet Lake or Intel will be in some major trouble.
