AMD Ryzen 7 3780U

► remove from comparison

The AMD Ryzen 7 3780U (Microsoft Surface Edition) is a mobile SoC that was announced in Oct 2019 as part of the new Surface Laptop 15. It combines four Zen+ cores (8 threads) clocked at 2.3 - 4 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (704 Shaders) clocked at up to 1400 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops.

Compared to the similar Ryzen 7 3700U, the 3780U offers the faster Vega 11 instead of the Vega 10 GPU.

The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPC (performance per clock) improvements. Furthermore, the 12nm process allows higher clock rates at similar power consumptions.

The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Ryzen 7 3780U should be slightly ahead the Ryzen 7 2700U. In our benchmark the Ryzen 7 3700U and therefore also the 3780U could not pull ahead much compared to the average Ryzen 7 2700U.

Intel Core i7-9850H

► remove from comparison

The Intel Core i7-9850H is a high-end processor for laptops with six cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.6 and 4.6 GHz (4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i7-8850H, the 9850H offers only improved clock rates.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to a similar clocked Kaby Lake processor like the Core i7-7920HQ (3.1 - 4.1 GHz). Single-core performance has not improved since its Kaby Lake predecessor. Compared to the i7-8850H, the performance improved only slightly.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz (rumored). The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i7 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.

AMD Ryzen 7 2700X

► remove from comparison

The AMD Ryzen 7 2700X is a high-end desktop processor with 8 cores (16 threads) that was announced early 2018. It is based on the revised Zen+ cores and at launch the fastest Ryzen CPU. The CPU cores clock at 3.7 GHz base and using Precision Boost 2 up to 4.3 GHz. All 8 cores and 16 threads can clock up to 4 GHz. The 8 cores are divided in two cluster (4 cores each with own L3 cache) connected via Infinity Fabric.

Compared to the older first Ryzen generation (e.g., Ryzen 5 1700X), the second generation is manufactured in an improved process (12nm called), offers and improved Precision Boost 2 (especially in partial load of the cores) and faster cache and memory speeds.

See our second generation Ryzen review for detailed benchmarks and information.

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.

Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.

If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.

DirectX is used in games, with newer versions supporting better graphics.

A higher transistor count generally indicates a newer, more powerful processor.

OpenGL is used in games, with newer versions supporting better graphics.

Performance

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.

More threads result in faster performance and better multitasking.

A larger L2 cache results in faster CPU and system-wide performance.

When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.

A larger L3 cache results in faster CPU and system-wide performance.

A larger L1 cache results in faster CPU and system-wide performance.

More data can be stored in the L2 cache for access by each core of the CPU.

Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.

More data can be stored in the L3 cache for access by each core of the CPU.

Ryzen 7 3780u amd

Comparing the Hardware

Last week I was lucky enough to get my hands on a new AMD Ryzen 7 15" Surface Laptop 3 in Platinum finish, and I couldn’t be happier with it. Initial reviews from various tech outlets were fairly mixed, however it seems that all of the review units Microsoft supplied most publications were the AMD Ryzen 5 with Vega 9 graphics variety. Because of this, there aren’t a whole lot of published benchmarks for the Ryzen 7 with Vega 11 graphics, so I thought I’d provide my findings here for those that may be interested to see how it stacks up with other devices it the same space.

For brevity’s sake, I am going to stick with the benchmarks in this post. If you’d like to hear about all of the details for the first 15" Surface Laptop models, be sure to check out the great in depth review from AnandTech: The Microsoft Surface Laptop 3 (15-Inch) Review: AMD Ryzen Surface Edition. In it, they had this to say:

The Surface team continues to make some of the nicest devices around, and the Surface Laptop 3 upholds that tradition. The attention to detail on items like having every single device tested to ensure the initial opening of the laptop can be done with one finger is the kind of fanaticism not normally seen in the laptop space. The entire design is sleek, smooth, and light, and the color options are a welcome way to add even more choice for consumers.

All in all, I agree with just about everything stated within the AnandTech review, but in short — benchmarks aside, I love my 15" Surface Laptop 3. So much so, that I’ve opted to kick my work provided Dell to the curb.

The Surface Laptop 3 comes in several flavors to choose from, including both 13.5-inch and 15-inch sizes, and Intel Core i5–1035G7, Intel Core i7–1065G7, AMD Ryzen 5 3580U, and AMD Ryzen 7 3780U CPU options. The Microsoft Surface Edition AMD Ryzen CPUs are only available in the 15-inch consumer version of the Surface Laptop 3, while the business version of the 15-inch Surface Laptop 3 and all 13.5-inch versions are powered by Intel CPUs and graphics.

The AMD Ryzen™ 7 3780U Microsoft Surface® Edition Processor found in the 15-inch Surface Laptop 3 is a quad core, 8 thread CPU with a base clock speed of 2.3GHz and a max boost clock speed of 4GHz. The 3780U also features Radeon RX Vega 11 Graphics with a total of 11 GPU cores, and the GPU is where the AMD Ryzen Surface Laptop 3 devices separate themselves from their Intel counterparts.

For my Surface Laptop 3, I opted for the Ryzen 7 model with 16GB of RAM, a 512GB SSD, and Radeon RX Vega 11 Graphics which has a base price of $2099. While the top-end configuration at $2799 has double the storage and memory of my Surface Laptop 3, its compute and GPU benchmarks should be similar to my Surface Laptop’s configuration.

Here, I will be comparing the Ryzen 5 3580U Surface Laptop 3 directly with the Ryzen 7 3780U Surface Laptop 3. If you’d like to see how it stacks up against similar devices in the market, I’d like to point you back once again to the AnandTech review, which posts it’s benchmark findings for the Ryzen 5 3580U among a plethora of devices.

Using the data I provide you here, you should be able to correlate where the Ryzen 7 3780U stacks up compared to AnandTech’s findings. I do not want to reprint their findings here in their entirety, as benchmarking that many devices likely took many, many hours — and they deserve the click for that hard work. Here is one of the many examples that they provide:

Mirroring what AnandTech did in their review, here’s a snapshot of the AIDA64 CPUID results for my device:

I was not able to recreate every single benchmark that AnandTech performed in their review, but I was able to recreate nine System Performance, and seven GPU Performance benchmarks, which should be a good comparison. In the table below, you can see how the 15-inch Surface Laptop 3’s Ryzen 5 3580 compares with the Ryzen 7 3780U and the Surface Laptop 2’s Core i7–8650U.

  • The Ryzen 7 3780U took seven of the nine system performance benchmarks, including: All four PCMark 10 tests, the Cinebench R15 Multi-Thread benchmark, Mozilla Kraken, and Google Octane.
  • The Surface Laptop 2’s Core i7–8650U held strong with the Single-Thread Cinebench R15 and WebXPRT 3 benchmarks.

The table below highlights how the 15-inch Surface Laptop 3’s Vega 11 GPU (3780U) stacks up against the competition, including it’s weaker sibling the Vega 9 (3580U), and the Surface Laptop 2’s integrated Core i7–8650U graphics.

  • The Ryzen 7 3780U’s Vega 11 GPU handily takes five of the seven benchmarks, including: 3DMark First Strike, 3DMark Sky Diver, 3DMark Cloud Gate, 3DMark Ice Storm Unlimited — Graphics, and the GFXBench 5.0 Aztec Ruins Normal 1080p
  • The Surface Laptop 2’s Core i7–8650U took down the remaining two benchmarks: 3DMark Ice Storm Unlimited, and 3DMark Ice Storm Unlimited — Graphics

As one might expect, the storage performance metrics as measured by CryastalDiskMark from the 512GB SSD found in my Ryzen 7 Surface Laptop 3 are nearly identical to the results from the 256GB SSD found in the AnandTech benchmarks. The Surface line of products aren’t known for their speedy SSDs, but for most workloads, they’ll do just fine.

Overall, the numbers show that the AMD Ryzen 7 3780U powered Surface Laptop 3 more than holds its own in the mobile CPU space, with the Vega 11 GPU being a big differentiator.

Obviously the Vega 11 isn’t like having a dedicated GPU, but it does greatly improve overall performance at a very low power draw while allowing you to get some light gaming in, if that is your thing.

In the past week I’ve played The Outer Worlds, Astroneer, Everspace, and Surviving Mars while on the road… and I look forward to playing further titles while enjoying countless more hours on the first AMD-powered Surface device.

Review: Microsoft Surface Laptop 3: AMD Ryzen 7 vs. Intel Core i7

Introduction

Microsoft's announcement of a 15in Surface Laptop 3 back in October didn't come as much of a surprise, but the decision to lead with an AMD Ryzen configuration certainly raised an eyebrow and could be viewed as a turning point for AMD's fortunes in the mobile space.

A genuine cause for concern over at Intel? The chip giant's supremacy has already been eroded on the desktop - where you might argue that AMD Ryzen is now the superior option - yet when it comes to laptops, Intel reckons it still holds the upper hand. To prove its point, we've been sent two almost identical Surface Laptop 3 review units for comparison purposes. The difference? One is powered by an AMD Ryzen 7 3780U Surface Edition, the other an Intel Core i7-1065G7.

This head-to-head makes for a fascinating comparison, as plenty has been made of the AMD-Microsoft partnership. The two industry heavyweights already work closely in terms of gaming - Xbox, remember, is powered by AMD hardware - and the introduction of a Ryzen-based Surface is a major design win in a market that rival Intel has dominated for many, many years.

When The Chips Are Down

AMD describes the collaboration as "a shared vision to bring the best of both companies together to revolutionise the laptop," citing tens of thousands of hours of co-development to create a custom Ryzen mobile processor specifically optimised for Surface Laptop 3. Said chip, dubbed Ryzen 7 3780U Surface Edition, is in fact a specially-binned variant of the existing four-core, eight-thread Ryzen 7 3700U, allowing for an increase of compute units, from 10 to 11. The resulting Vega 11 IGP promises a reasonable uptick in graphics performance, yet the Surface Edition part retains familiarity with others in AMD's Picasso stable, meaning the use of a 12nm Zen+ architecture, rather than the 7nm Zen 2 currently leading the charge on desktop and server.

Over in the blue corner, Intel can't be accused of resting on its laurels as the Core i7-1065G7 is one of the first chips to be built using the firm's 10nm Ice Lake architecture. As is often the case with an iterative design, there's the promise of a deeper, wider and smarter layout featuring more cache, an increase in allocation units and execution ports, as well as an improvement in branch prediction. Said optimisations are bolstered by an accompanying Gen 11 GPU offering up to 64 Execution Units, as is the case for the i7-1065G7's Iris Plus IGP, and the 10nm package also includes baked-in support for Wi-Fi 6 and Thunderbolt 3, alongside a new memory controller supporting LPDDR4X at 3,733MHz.

Breaking the two configurations down into a table format suggests a closely-matched contest. We don't expect a huge gap in terms of CPU performance, and though we're intrigued to see whether or not the beefed-up IGPs can handle basic gameplay, we're more interested in overall platform refinement. AMD's promise of custom firmware and drivers for the Surface Edition processor bodes well, however Intel has the advantage of faster memory and superior Wi-Fi, and then there's the question of battery life. Whereas AMD's primary focus has been on desktop, Intel has spent years refining its mobile solutions to maximise longevity, and we suspect the Core i7 will outlast the Ryzen 7 in the upcoming battery tests.

Before we take a closer look at the laptop itself, it is also worth pointing out that the 15in Surface Laptop 3 is only available from Microsoft's consumer store in AMD Ryzen flavours. We presume this to be some form of exclusivity agreement with AMD, however those preferring the Intel option can quite easily purchase the Core i7 model from Microsoft's business store. Pricing for the two review units is similar and available colour options include platinum or black.

A Bigger Surface Laptop

As a component-focussed publication it is far too easy to devote our time to the AMD vs. Intel proposition, yet the bigger picture is a 15in laptop, and a beautiful one at that. Essentially an extended variant of the 13.5in model, the 15in Surface Laptop 3 retains the smooth, uncluttered appearance of its smaller sibling and feels suitably luxurious during use. Dimensions of 340mm x 244mm x 14.7mm are in line with our expectations of a modern 15in system, and the 1.5kg weight feels really well balanced.

While minimal in appearance, it is the attention to detail that continues to impress on Microsoft's Surface products. The display, for example, might not have the slimmest bezels, yet you can open the lid with a single finger thanks to a hinge mechanism that feels effortless. There isn't a great deal of wobble when using the touchscreen, and the tall 3:2 PixelSense panel continues to serve as a star attraction. An unusual 2,496 x 1,664 resolution ensures the same pixel density (200 PPI) as the smaller 13.5in model, and though brightness and contrast isn't quite as epic as Microsoft's Surface Book, we continue to be dazzled by the firm's PixelSense panels; we're frankly amazed more laptop manufacturers haven't adopted a 3:2 aspect ratio that lends itself so well to productivity.

Below the display is a keyboard and trackpad combination that is easily one of the best in the business. Microsoft's backlit keyboard has an extremely quiet and likeable action, while the spacious precision trackpad is smooth and responsive while doing a fine job of palm rejection. There's no option of soft alcantara fabric - that's sadly limited to the 13.5in model - yet as a ThinkPad user, I'm willing to admit that Microsoft's keyboard and trackpad are now at least on par, if not better.

So clean is the exterior that you may be left wondering where certain features reside. The IR camera system is barely visible in the top bezel, and there aren't any speaker grilles to speak of, as Microsoft has the stereo sound system embedded beneath the keyboard. Surprisingly, there's little detriment to sound quality, with Surface Laptop 3 delivering crisp audio and enough volume to fill a medium-sized room.

If there's a disappointment, it is that Microsoft hasn't used the larger 15in form factor as an opportunity to add more I/O, or indeed a higher-capacity battery. Keeping things simple, the laptop features just four ports; USB Type-C, USB Type-A, a headphone jack and the magnetic Surface Connect charging port. There's no support for Thunderbolt 3, and while the Type-C jack can be used for charging, you might expect another USB port or perhaps an SD card reader on a machine of this size.

Surface Laptop 3 also deserves plaudits for its cooling configuration. The internal fan remains off during most tasks, making for a peaceful computing experience, and if and when it does kick in, it does so gradually, keeping noise levels down to a minimum. This is the level of refinement we expect at the premium end of the market, but during regular use, do you notice any difference between the Intel and AMD machines?

Truth be told, in a blind test we imagine most users would struggle to notice any change; they both feel fast, responsive and free of any niggling software issues. However, put them side by side and the Intel has a slight edge in terms of everyday performance. Apps tend to install that little bit quicker, and when restoring Windows 10 to factory defaults, the Intel machine completed the task a couple of minutes faster than the AMD. These are small margins, mind, so let's roll the benchmarks to find out what, if anything, sets the two configurations apart.
