The Microsoft Surface Laptop 3 Showdown: AMD's Ryzen Picasso vs. Intel's Ice Lake

After many tests, it is very clear that Intel’s Ice Lake platform offers a significantly faster CPU, and the results were unsurprising. Although the Ryzen Mobile 3000 platform did launch in 2019, it already struggled on CPU tests against the older Skylake core processors. But on the GPU side, Intel is the one that needs to play catch-up. Previous to Ice Lake, Intel’s standard GT2 GPU platform, found on almost all U-Series 15-Watt processors, offered 24 execution units of their Gen 9.5 GPU. AMD squeezed their Vega GPU architecture into their Ryzen SoC, which could easily double the performance of the Gen 9.5 GT2 GPU.
Ice Lake is Intel’s first real attempt to make a powerful iGPU a standard feature for their CPUs, although it is only a first step. But the new Gen 11 architecture brings some improvements such as more advanced tile-based rendering, variable rate shading, and of course the LPDDR4X-3733 memory adding significant bandwidth, greatly helping the GPU. The biggest change though is just how much die space Intel has dedicated to graphics, jumping from 24 EUs on a full GT2 to 64 EUs on a full GT2 part such as the Core i7-1065G7. And, following in AMD’s footsteps again, Intel is offering cut-down GPUs on lower-spec processors. It’s confused their already confusing processor naming, but the lowest-spec Core announced so far still has 32 EUs, meaning it is still better than the previous gen even at the “G1” level.
AMD has some tricks up their sleeves as well. For the Surface Laptop 3, Microsoft requested a slightly more powerful configuration for their Surface-branded processor. While the CPU side matches the same specifications as the non-Surface CPUs, Microsoft's processor SKUs add an extra GPU Compute Unit to both its Ryzen 5 and Ryzen 7, bringing them to 9 and 11 respectively. So the Surface Laptop 3 should be the best possible showcase for GPU performance on the 3000 series Ryzen mobile APU.
Before the results, let’s go over the driver situation. The Intel system ships with an updated driver over what we used on the Dell XPS 13 2-in-1, which resolves the 3DMark issues we saw on that laptop. The driver is from 2019-11-06 and is version 26.20.100.7463. The AMD platform’s driver is from 2019-10-07 and is version 26.20.12027.5004. Unfortunately, the AMD driver can’t be updated from AMD directly, and instead will be released by Microsoft. The current driver has some quirks, so an updated driver is needed for usability, but it did not prevent any GPU workloads from being run. But, the AMD system would only output 1280x720 where we normally test at 1366x768, and attempts to output to an external monitor were thwarted by the buggy driver, so be aware that in most of the gaming tests, the AMD system was outputting at a slightly lower resolution.
Let’s see how the do starting with some synthetics, and then moving to some real-world games.
3DMark
3DMark offers several tests of varying complexity, from Fire Strike as the most demanding, to Ice Storm Unlimited, which can be run on tablets. Here the Ice Lake platform pulls ahead, with better CPU performance helping quite a bit, although the Ice Lake’s Iris Plus graphics is also able to outperform Vega 11 as well.
GFXBench
Kishonti’s latest GFXBench suite added DirectX 12 tests to the fold, making it far more relevant than the older OpenGL versions available on the desktop previously. AMD’s previous work in low-level drivers when they developed Mantle has provided the groundwork for DX12 as well, with Vega 11 offering slightly better results than Iris Plus in this test.
Tomb Raider
Running at our value settings, Tomb Raider was easily playable on both systems, with framerates approaching 100 FPS. The Ice Lake platform performed better on this test.
Rise of the Tomb Raider
The second installment in the Tomb Raider series offers much more demanding visuals, and both systems struggle to play it at our value settings. The DirectX 12 title performs slightly better on Vega, and with some additional settings tweaks, the game would be playable, which is not something you could have said on an integrated GPU previous to Ryzen and Ice Lake.
Strange Brigade
A new title we’re bringing to our laptop suite is Strange Brigade, which scales down nicely on integrated graphics. This game also supports DirectX 12, and as tends to be the pattern, performs very well on Vega 11.
F1 2017
Back with a DirectX 11 title, we see that Intel has again closed the gap, and this game tends to be somewhat CPU bottlenecked as well, so the Sunny Cove cores likely help out here too, but once again Vega 11 wins, if only by a nose.
F1 2019
Codemasters updated the underlying EGO engine to support DirectX 12, which was utilized on this test. Despite that, the Vega 11 GPU is a bit slower than the Iris Plus in this test.
Far Cry 5
Both systems are within striking distance of being playable, which is somewhat remarkable since the Far Cry series is one of the most popular AAA first-person shooters. The Vega 11 GPU was slightly ahead, which is somewhat surprising as this game tends to be CPU bound, but clearly at this low of a GPU limit that hasn’t come into play yet.

@Samus: It is sad that some people would buy the inferior Ryzen 15inch without even knowing that there is a better Intel 15inch version available and you don’t have be a business person to buy it. Pathetic anti-consumer attempt from Microsoft.0ldman79 - Tuesday, December 17, 2019 - link
Pretty sure it's because Intel is having issues supplying the chips to the OEMs.Microsoft, like most OEM, are hedging their bets and designing systems to run AMD chips.

It's sad that anyone would buy an overpriced Microsoft Surface.MBarton - Monday, December 30, 2019 - link
Because Intel 10nm yields are so woefully pathetic that Microsoft had to source AMD's old Zen parts to help make up for the lack of parts.Polacott - Saturday, December 14, 2019 - link
I guess for some people, the extra cpu processing power is not needed however the extra storage can be a handy thing? processors are quite powerful these days. Of course for me I would choose higher processing speed over storage, if it were for my mother i would choose storage over speed.Brett Howse - Saturday, December 14, 2019 - link
You can get the same storage in both.Polacott - Sunday, December 15, 2019 - link
For the dame money?Brett Howse - Sunday, December 15, 2019 - link
The business model with Intel is $100 more but comes with Windows 10 Pro which is a $100 upgrade over home, so for the hardware, it's the same money, but the business version is overall $100 more expensive.m53 - Sunday, December 15, 2019 - link
@Brett: Agreed. In addition it comes with a better and more expensive ram. so the intel version is not just insanely faster, it is also the better value overall.Polacott - Saturday, December 14, 2019 - link
Considering Microsoft is just giving Windows Home in AMD offer and Pro + better ram on Intel one, they must be getting the intel cpu at a tremendously affordable price or up pricing the AMD offer considerably.
