Ryzen 7 4700U review: AMD’s budget 8-core crushes Intel’s 10th-gen chips, again - haygoodcapaidep35
The AMD Ryzen 7 4700U arrives at a key import for laptop CPUs. After AMD launched its 7nm Ryzen 4000 CPU family at CES and dealt a first, quelling blow with the Ryzen 9 4900HS chip in high-end notebook PCs, the company has its eyes on the real prize: U-class laptops. Yes, those sub-three-pound slivers (known in a prehistorical life as Ultrabooks) everyone nonchalantly carries into meetings or lays flexible in a cafe.
The vast majority of laptops nowadays fit into this category. Traditionally they're known to sacrifice performance for flatboat burthen and diluent design. AMD's offerings in this area have been weak in the past, so the company focused on optimizing Ryzen 4000 for diluent notebook PCs. Everyone wants to eff if AMD's Ryzen "U" chips finally have what it takes.
Our quiz subject, the first Ryzen 7 4700U laptop we've tested, is Acer's Swift 3. Yes, wear't rub your eyes, we're virtually to put a budget $650 laptop against laptops that cost galore times more. To find out which one wins, read connected.
Acer The volume of our testing was done on a "budget" Acer Fleet 3 with a 14-inch screen, 512GB SSD, 8GB of LPDDR4X/3733 and Ryzen 7 4700U.
How we tried and true
When we screen a new CPU, we footrace a lot of extra benchmarks. This review shows a selection of those tests. Click this unite to find our full bench mark results for Ryzen 7 4700U.
As you can't test a laptop CPU by itself, we hand-picked three models to represent their respective CPUs. Acer's Swift 3 SF314-42 debuts with AMD's Ryzen 7 4700U, code-named "Renoir." This budget CPU features 8 cores, merely without Symmetrical Multi-Threading (that's reserved for the Ryzen 7 4800U), so IT's limited to 8 total threads. The Swift 3 comes with 8GB of LPDDR4X/3733 RAM and a 14-inch reveal.
Representing Intel are Dell's XPS 13 7390 with Intel's Comet Lake U 10th-gen CORE i7 10710U, and Dingle's XPS 13 2-in-1 7390 with Intel's Internal-combustion engine Lake 10th-gen Core i7-1065G7. The top-end Comet Lake U features 6 cores and 12 duds, spell the Ice Lake chip features 4 cores with 8 togs. We study both XPS laptops to be good comparisons, as they normally top the charts in carrying out over most of the laptops we see. They both have 16GB of RAM compared to the Acer's 8GB, but the Dell XPS 13 7390 uses slower LPDDR3, while the XPS 13 2-in-1 uses LPDDR4X/3733. The XPS 13's display is 13.3 inches, and the XPS 13 2-in-1's screen is 13.4 inches.
All three laptops were spouting the latest public build of Windows 10 (1909 18363.815) and the latest drivers and UEFI, to bring them in seam with all of the security mitigations. While the Acer didn't appear to have any performance settings other than Window 10's slider (remember, it's a $650 budget laptop), both Dingle XPS laptops were scarper using their Ultra Performance settings.
We as wel want to mention that testing terzetto laptops at home during shelter-in-grade required some adjustment. With ambient temperatures e'er shifting in our test lab-slash-dining-room, we stopped testing when the temps got too high. For consistency, all of the results we show are from the laptops running the same tests at the same time.
The last fact we should credit is the price. While both XPS 13's are essentially the emollient of the crop and priced accordingly, the Swift 3 here is a commoner at $650.
Gordon Mah Ung You get a Ryzen 7 4700U! And you get a Ryzen 7 4700U! OK, not genuinely, but wouldn't it be cool if AMD had an Oprah moment?
Ryzen 7 4700U CPU Performance
We'll kick this off with Maxon's Cinebench R20. It's a recently updated test made to measure how fast a CPU renders a 3D model. It uses the company's Cinema4D engine, which is integrated into major products including Adobe brick Premiere Pro CC.
Intel has argued that using 3D modelling benchmarks isn't useful in thin-and-light laptops, because very hardly a people buy them for that large-hearted of work. While we somewhat agree, we also see there's decent performance potential now in thin-and-lights that you could shed few pounds (in power brick, likewise), yet still enjoy multi-core performance.
As the chart below shows, you could bask plenty from Ryzen 7 4700U, which was 23 percent faster than Intel's most advanced 10th-gen Core i7-1065G7 microchip. It's also most 14 percent faster than Intel's crown-end 6-core, 12-draw Core i7-10710U. Call up: This Ryzen 7 4700U doesn't even rich person SMT turned on.
IDG AMD's budget Ryzen 7 4700U in the Acer Blue-belly 3 easily puts both premium Intel 10th-gen U-chips to sleep.
To focus on Intel's contention that single-rib performance matters most, we apply Cinebench R20 do to a lonesome train of thought. It's not the same as running a spell-check in Microsoft Word, but it does give you an denotation of the chip's performance under charge.
IDG Cinebench R20 puts the Ryzen 7 slightly ahead of both Intel chips, simply it's essentially a tie.
The results above are essentially a tie. The "winner" here is Ryzen 7 4700U, which comes in slightly ahead of the Meat i7-10710U Comet Lake U. You'd expect the Comet Lake U's 4.7GHz turbo hike up clock to win this all over the Ryzen 7 4700U's 4GHz hike up time, only Cinebench R20 takes far thirster to run than the old Cinebench R15 and uses AVX, AVX2, and AVX512, which can drag down the cost increase clocks. (See our Cinebench R15 results at the end of the review.)
Our next CPU test measures performance under more stressful conditions. We normally use an older, 0.9.9 version of the free HandBrake utility to convert a 30GB, 1080p television using the Android Tablet preset. Both 1080p and Android tablets are roughly arsenic farther behind us as 2014, though, so we took this chance rill the latest public variant of HandBrake, version 1.3.1, and convert the ASCII text file 4K video, Tears of Steel, using the H.265 Matroska 1080p/30 preset.
For this prove, the encode is done strictly on the x86 cores. Obviously, the shorter result is better, because that means less time waiting for the encode.
As you can see below, Ryzen 7 4700U wins past a mile, coming in or so 30 percent quicker than the Core i7-10710U. Against the more advanced 10nm Core i7-1065G7, you're looking at at a 36-percent difference. Call back, the Ryzen 7 4700U doesn't even have SMT.
IDG The Ryzen 7 4700U crushes the Core i7-10710U and Core i7-1065G7 in an HEVC-encode test.
The previous write in code uses the x86 side to execute the picture transcode. That's kind of old-schoolhouse when you have the advanced media engines in the chips. To look at that, we used the same 4K Tears of Steel video and encoded information technology using the H.265 preset; even so, we switched it to use the QuickSync encoding engine for Intel, and AMD's new VCE (Video Coding Engine). We set all three to use the Main Profile setting and Peak Skeletal frame Rate at 30 fps (the QuickSync preset defaults to the experienced Variable Frame Charge per unit scope, set to Same as Source).
IDG VCE pulls verboten a decent win against QuickSync in our H.265 cypher test.
As you can see in the chart above, AMD's VCE crosses the finish line first, about 11 percent faster than the Core i7-1065G7. The Heart and soul i7-10710U and its older media engine are about 28 per centum slower.
AMD's VCE locomotive wins on carrying into action, but one variable we don't consider is the quality of the video encoded by QuickSync and VCE. Even though some are using the same settings in HandBrake, information technology's not quite an equal if one is producing inferior video. Perchance we'll ask our video nerds to check the video quality. For now, we'll tranquillize give it to AMD's VCE. And if this isn't enough Central processor data for you, check out our companion story with the full roster of benchmarks on Ryzen 7 4700U.
Ryzen 7 4700U GPU Performance
For the incoming section we'll progress to artwork performance. The 14nm, 10th-gen Core i7-10710U offers in essence the same graphics railway locomotive we've seen for many years now, Intel UHD, with a number to refer its execution. Intel has more fresh born the number, and we sometimes don't equal examine the U anymore either. The 10nm, 10th-gen Core i7-1065G7 gets a much more advanced Iris Positive graphics locomotive engine, which was a welcome change when introduced. IT's enough to make low-power discrete Nvidia MX graphics nervous.
AMD's Ryzen 7 4700U features improved Radeon Vega cores, which the company said are markedly faster and more efficient than Lope Felix de Vega Carpio cores on older process generations. The Ryzen 7 4700U features 7 compute units at heart, which can offer 1080p gaming capability. But let's be true to life: It's a limited thermal gasbag with simply LPDDR4X/3733 vs. a discrete GPU's GDDR6. It's only going to take up you heretofore. We've said the same about Intel's much better Iris Nonnegative graphics, too.
Still, a posteriori tests help illustrate the limitations. 3DMark's Sky Underwater diver (below) is intimately suited for basic play measurements. Atomic number 3 you can see, the Ryzen 7 4700U with Radeon graphics is about 12 percent quicker in the graphics-only sub-trial run, which mostly filters out CPU performance. You can find our results for 3DMark Fire Strike and much in our companion clause of altogether the benchmarks we ran happening Ryzen 7 4700U.
IDG Ryzen 7 4700U Battery life
Perhaps one metric that overshadows all is battery living. Our video rundown test uses the unvarying Tears of Sword 4K telecasting and loops it victimisation Windows 10's Movies & TV player (the nearly efficient one in town). We put the laptop into airplane mode, connect earbuds to minimize the speaker driver impact, and set screen brightness to 250 to 260 nits.
Federal Reserve note that this chart includes roughly older test results. We used the confirmed scores from the reviews of some the Dell laptops, As OS and UEFI updates should not feign this test. We too brought in the results from recent Intel-based Swift 3 laptops we've tested, with 8th-gen Whisky Lake and 10th-gen Ice Lake chips.
IDG Most of the Acer Swift 3 laptops we've tried and true, incuding this new one with Ryzen 7 4700U, have middling battery life.
Here's the one place where Ryzen 7 4700U stumbles. It posts an unremarkable 8 hours and 10 minutes of runtime, compared to nearly 10 hours for the XPS 13, and well-nigh 12 hours for the XPS 13 2-in-1. Also note that the XPS 13 we tested features a 4K test, which consumes far more index than 1080p panels much as the 1 in the Acer Fleet 3. The same XPS 13 with an FHD screen power wealthy person lasted an additional three to four hours.
To be fair, the Ryzen-supported Sceloporus occidentalis 3 is mostly in line with deuce of the three other Kernel-supported Fast 3's we've tested. At this point, we think it's safe to say that battery life on the Acer Swift 3 is middling across the board, and it may undergo goose egg to do with the Ryzen chip. We'll wait until we've time-tested 7 or eight Ryzen 4000-settled laptops to establish a drift for this CPU family. (We should note that the Ryzen 9 4900HS in the Asus ROG Zephyrus G14 gave us fantastic video rundown performance).
Ryzen 7 4700U: The chip that won't quit
To wrap IT up, we'll help you visualize the strength of the Ryzen 7 4700U: CPU performance. For that we use the elder and lighter Cinebench R15 and rill it from 1 thread to the maximum amount. For the Comet Lake U Core i7-10710U, that's 12. The runs are performed sequentially, with a few minutes' rest in between.
In the chart on a lower floor, we view a fixation in functioning with the Core i7-10710U that is rough to understand. We think it power be our issues with the ambient room temperature. On a cooler morn we'll rerun this, but remember: We ran the Ryzen 7 under the same conditions.
IDG We run Cinebench R15 across every of the CPU cores to sacrifice you an idea of how the chips execute.
We as wel graph out the performance divergence, at a lower place. As you can see, the Ryzen 7 4700U is underwater on those light loads, where the higher encourage clocks of the Marrow i7-10710U have an reward in Cinebench R15. The Ryzen 7 4700U opens up a big lead down the home stretch. Even though the Inwardness i7-10710U has 12 duds in a test that favors more threads, the 8-core-only Ryzen 7 4700U fights IT to a standstill. Overall, we'd say it's a win for AMD, especially when you consider the Ryzen 7's better GPU.
IDG Intel's most advanced 14nm U-chip, the Core i7-10710U, leads the Ryzen in single-threaded performance. It's mostly a tie along heavy gobs, with the 8-meat-entirely Ryzen 7 offering more interesting carrying out spikes.
The to a greater extent interesting engagement is between AMD's 7nm Ryzen 7 4700U and Intel's 10nm Core i7-1065G7. We've already seen how close the two can cost at times, even in graphics performance. The main issue for the Intel chip is it doesn't go beyond 4 cores. When you liken the Ryzen 7 4700U against the Core i7-1065G7, it looks like this.
IDG Multi-core performance on AMD's new Ryzen 7 4700U (green) vs. Intel's nigh advanced 10th-gen Heart i7-1065G7 (disconsolate).
That probably doesn't look similar much, so present is the performance difference by pct. Both chips are in reality dead even on single-core performance, but as you ramp up, the Ryzen 7 4700U doesn't look back. It's basically multiple digits, with a banging 22-percent difference at 8 threads. The basic lesson is while Hyper-Threading helps quite an bit, it's not enough to beat 8 physical cores. This is likely to look even uglier with the Ryzen 7 4800U, which has SMT (AMD's Hyper-Threading) switched on.
IDG The 4-core, 8-draw Core i7-1065G7 can't hang with the Ryzen as threads go up.
Ryzen 4000 continues to change the game
Ryzen 4000's journey is by far not everlasting. During our Ryzen 7 4700U testing, we tried to create a workload using Windows 10's overlooked only awesome Video Editor (yes, that's its name). We took the 4K Tears of Steel video, added surly titles, 3D effects, and "denim" filter set up, exporting IT to 1080p.
On the Dell XPS 13 2-in-1, the project and export ran as smooth every bit butter—very impressive for an ultralight laptop. We tried the comparable with the Swift 3 and Ryzen 7, but the project simply adorned when hardware speedup (AMD's VCE) was enabled. We're sure this issue will be corrected erst Microsoft notices, but we bring this risen as a monitor that AMD is moving in to a world that's been for the most part centralised on Intel CPUs for a lengthened, long time.
Before we end this, we want to help lay some perspective on AMD's Ryzen 7 4700U and Acer's Swift 3. Remember that this is a budget $650 laptop with 8GB of RAM and 512GB SSD. IT's basically cooled by a solitary heat bagpipe and lover, vs. the intricate copper vapor Chambers of the XPS 13 2-in-1 or dual fans of the XPS 13. Even so, the Swift 3 was always well-behaved and never the archetypical to infract with fan noise. That's nearly the same experience we byword on Asus' ROG Zephyrus G14 on CPU operations. We can't order the same for just about Intel-based laptops when pushed hard.
Yet this modest Swift 3 budgetbook offers performance that actually puts it into the ballpark of Intel's 9th-gen H-class laptops. You can ensure that illustrated below, where we set down the Acer Swift 3 into a inner circle of H-class gaming laptops. The longer red line belongs to the Ryzen 9-powered Asus ROG Zephyrus G14.
IDG The Acer Swift 3 nates in reality perform as well every bit Intel's 9th-gen H-class CPUs in CPU operations.
We'll show it even so once more in the more intensifier HandBrake tryout, this time using the older version, where we transcode a 30GB 1080p MKV file exploitation the Android Pad of paper preset. The workload favors more cores and threads. The Genus Acer Swift 3 with its Ryzen 7 4700U is in strain with 6-core, 12-thread Pith i7-8750H and Congress of Racial Equality i7-9750H chips in laptops that weigh five pounds or Sir Thomas More, typically. Yes, those H-class gaming laptops would whup the Swift 3 frivolous in gambling—but in CPU performance, IT's way too close for comfort for Intel fans.
IDG Amazing: A Ryzen 7 4700U without SMT, fanny just virtually hang with 8th gen Core i7-8750H and Inwardness i7-9750H chips.
The Ryzen 7 4700U delivers merely surprising execution that raises the bar for what we've come to expect of U-category laptops. Only its battery life falls back to earth (and that May exchange as we see more than laptop computer implementations.) Overall, information technology's yet more proof of just how much of a game-changer the Ryzen 4000 CPUs are.
