Almost two years ago to the day, we had a chance to check out Acer’s Swift 3 laptop featuring AMD's first Ryzen Mobile platform, Raven Ridge. Acer has been a strong partner for AMD, generally being one of the first out of the gate with new designs featuring AMD’s latest platforms, and this year that partnership has played out again. Today we are taking a look at the newest AMD APU offering, the Ryzen 4000 "Renoir", which is at the heart of Acer’s latest iteration of the 14-inch Swift 3. With a brand-new AMD processor and some innovations in the Swift 3 design itself, both AMD and Acer have made some tremendous improvements for 2020.

Ryzen 7 4700U

The big news for 2020 is AMD’s new APU platform, codenamed Renoir. Selling as the Ryzen 4000 series, these new APUs bring a number of major updates to AMD's platform, as the company further sands down the rough edges from the Ryzen 3000 Picasso series. Key to this is a much-needed jump from GlobalFoundries' 12nm process to TSMC's class-leading 7nm process, giving AMD a much-wanted boost in transistor performance and overall energy efficiency. Coupled with a number of further optimizations at the chip and driver level, and AMD's latest APUs are proving far better suited for thin-and-light mobile designs than their predecessors.

Under the hood, like AMD's desktop processors introduced last year, the new Ryzen 4000 series APUs are the first laptop-focused products from AMD which feature their Zen 2 CPU cores. Designed hand-in-hand with TSMC's 7nm process, the Zen 2 architecture has further boosted AMD's performance across both IPC and clockspeeds, and the small cores have allowed AMD to get away with 8 of them in even a laptop APU. Meanwhile the iGPU is based on the same Vega architecture graphics as both the 2000-series and 3000-series APUs, but in a new configuration. Thanks to TSMC’s 7nm process, AMD has been able to crank up the GPU frequency much higher than before – so much higher that they’ve actually scaled back on the number of GPU compute units, while still promising improved GPU performance over the previous generation of APUs.

Ian had a chance to take the new Ryzen 4000 platform for a spin in early April, although that sample was the 45-Watt H series. Many of the concepts carry across though, so if you’ve not yet had a chance to catch up on Renoir, be sure to check out the Ryzen 9 4900HS review. The 45-Watt processor range is pretty much the standard in high-performance notebooks, but the vast majority of laptops on the market stick to the lower-powered 15-Watt range, which is what we have in the Acer Swift 3.

Acer has opted for what is likely to be one of the most popular SKUs in the AMD Ryzen 4000 range, the Ryzen 7 4700U. AMD has gone a very non-traditional route for this part, offering eight physical CPU cores, but disabling simultaneous multithreading (SMT). All of AMD’s H-Series lineup of 45-Watt processors do offer SMT, but only two of the new U-Series provide this, with the Ryzen 5 4600U offering 6 cores and 12 threads, and the Ryzen 7 4800U providing 8 cores and 16 threads, all in the 15-Watt thermal design power (TDP) that is so common on laptops. In the typical 15-Watt laptop space, AMD is the first to offer 8 cores, just not always with SMT.

On the GPU side, the Ryzen 7 4700U offers 7 Vega-architecture Compute Units (CUs), with a maximum clockspeed of 1600 MHz. Compared to the previous generation Ryzen 7 3700U, the GPU drops three compute units, but bumps the maximum frequency from 1300 MHz to 1600 MHz, so we shall see where this plays out in terms of performance.

The Acer Swift 3

Acer has managed to bundle a lot of product into the Swift 3. The 14-inch notebook features a 1920x1080 IPS display that, albeit lacking touch support, does get showcased well thanks to the Swift 3's thin bezel surround. The laptop ships with 8 GB of DDR4-3200, and though we would have loved to see LPDDR4X, the capacity is what is important here, and 8 GB is a good amount for a budget-friendly laptop like the Swift 3. Also, Acer has managed to outfit this notebook with a 512 GB SSD, which is fantastic. They will also be offering a less-expensive version with a Ryzen 5 4500U, 8 GB of RAM, and a 256 GB SSD.

Despite the strong APU, RAM, and storage offerings, Acer is not done there. The Swift 3 also features Wi-Fi 6 thanks to Intel’s AX200 wireless adapter, which means 2.4/5.0 GHz wireless support with 160 Mhz channels if your router is has the correct capabilities. There’s also an integrated fingerprint reader for Windows Hello Support, and the entire package is contained in an all-aluminum chassis which weighs just 1.2 kg / 2.65 lbs. Considering the $649 MSRP, this is an incredible value.

    It only bogged down while playing certain games. It was fine for decently hard work loads, encoding and light gaming. If you want to play Far Cry 5, this is a turd, as is any laptop with IGP. Reply

    But will it be 2.65lbs? Some people need portability. Reply

    This integrated graphics is very impressive, and the performance is just amazing for a 650 USD laptop.

    It isnt intended for gaming tho, we all know that. I am mostly impressed that it is an 8 core laptop.

    I am mostly happy things are getting cheaper and more powerful.

    Throttling a CPU to 8 watts is amazing? Not being able to cover the ancient sRGB color space with even somewhat-decent accuracy is amazing? Reply

    So, this laptop apparently doesn't show the performance of the AMD processor at all, because it has garbage cooling.

    "The laptop really struggled with its thermals, dropping the framerate into single digits often. The device attempted to run at around 18 Watts of power draw, slightly over the 15 Watt TDP, but in fact only averaged around 8 Watts during this run."

    8 watts versus Intel's 25?

    "performance here will be strongly impacted by the TDP as well as cooling of the systems. Both AMD parts are 15W TDP designs, while the Intel chip sustains 25W."

    Does it sustain 25 watts or is that merely the TDP? Knowing Intel, I assume it goes beyond that.

    "The generational improvements here aren’t enough to catch up to Intel’s Sunny Cove cores in the Ice Lake i7-1065G7. Although that core might be running at higher single-core TDPs and power consumption, it still makes for a big gap in some of the more instruction pressure and cache pressure high workloads such as 500.perlbench_r and 502.gcc_r where the Intel chip still has a considerable lead in."

    Might?

    It seems that your "15W" information in the article graphic is inaccurate.

    Shouldn't it be 8+ watts?

    What do you expect from 600ish dollars guys, cmon get reality check, this product is clearly punching above it's own weight. Reply

    What's the exact price of this thing in India? When it will be available? Reply
  • Oingles - Thursday, May 7, 2020 - link

    They have packed in a lot for the price, I would buy this if it had a much better display option. 16GB would be good too. Happy to pay more for that. Reply

    Does anyone know if this thing has a sodimm upgrade slot?

    8GB ram is so last-year for a $700 laptop (especially one where you have to share ram with the APU)!
