System Performance: AMD Renoir H

AMD’s Renoir platform has been a game-changer in the laptop space for the Santa Clara company. With the previous laptop platform, Picasso, AMD offered competitive,, but not class-leading performance, especially on their integrated GPU, but were let down by high platform power draw, which was a major hurdle to overcome in a battery-powered device. Also, Picasso featured the AMD Zen CPU cores, whereas AMD’s desktop platform had moved to Zen 2. With the introduction of the AMD 4000 series laptop platform known as Renoir, AMD really delivered a triple-punch, moving to their newest 7 nm Zen 2 cores, as well as addressing their high idle power draw, and offering up to eight cores and sixteen threads in both their U-Series 15-Watt designs, and H / HS series 45-Watt / 35-Watt laptop processors. AMD went from “competitive, but” to class-leading overnight.

For a full deep-dive into the AMD 4000 platform, please check out Ian’s launch-day review featuring the AMD Ryzen 9 4900HS.

Moving back to the Acer Nitro 5, Acer is offering two Renoir-based options, with the entry-level design featuring an AMD Ryzen 5 4600H, and the upgraded model moving to the Ryzen 7 4800H. Both are nominal 45-Watt TDP parts, with the Ryzen 5 offering six cores and twelve threads, from 3.0 to 4.0 GHz. The 4800H offers eight cores and sixteen threads, from 2.9 to 4.2 GHz. In our Ryzen 5 powered review unit, the processor is paired with 8 GB of DDR4 RAM in a single-channel configuration, which will somewhat impact CPU performance, but offers the owner an easier, less expensive option to upgrade to 16 GB in the future.

To see how the Acer Nitro 5 performs, it was run through our laptop benchmark suite. To compare the results to any device we have tested, please use our online Bench. As an interesting comparison we have included the ASUS ROG Zephyrus M15, powered by a six-core i7-10750H, with the same TDP and core count as the AMD Ryzen 5 4600H in the Acer Nitro 5, as well as the eight-core Ryzen 7 4700U powered Acer Swift 3, and some quad-core Ice Lake platforms with and without dedicated graphics. The comparison systems are not based on price – the Acer Nitro 5 is easily the most inexpensive device here with a dGPU – but on platforms, so please keep that in mind. Where possible, the ASUS Zephyrus G14, which was the launch platform for the Ryzen 4000 series, is also included, however Ian’s CPU testing suite does not perfectly match the Laptop suite, so data is not available for all tests.

PCMark 10 - Overall

Offering a range of sub-tests, UL’s PCMark 10 simulates real-world tasks for office productivity, digital content creation, and typical tasks a home-user may do such as web and video chats. The Acer Nitro 5 does very well here, although it can not quite match the 8-core Ryzen 7 4700U in many of the tests. The included GTX 1650 does propel it ahead in content creation, however. The ASUS M17, with a 5.0 GHz maximum frequency, does edge the Ryzen 5 4600H, and the large GTX 1660 Ti GPU also helps. However the ASUS Zephyrus G14 with the “35-Watt” Ryzen 9 4900HS and RTX 2060 is able to outshine the rest of the systems.

Cinebench R20

Cinebench R20 - Single-Threaded Benchmark

Cinebench R20 - Multi-Threaded Benchmark

Cinebench is a pure compute workload, testing a CPU’s execution resources without much else getting in the way, like memory. It favors fast frequencies, high IPC, and more cores on the multi-threaded version of the test. The slightly lower boost frequency of the Ryzen 5 4600H, peaking at only 4.0 GHz, holds the system back on the single-threaded results, but with six cores and twelve total threads, the Ryzen 5 competes well with the Core i7-10750H, and stretches its legs on the U-Series processors. The Ryzen 9 4900HS, with 8 cores, 16 threads, and a 4.3 GHz maximum turbo, easily outclasses other processors here.

Handbrake

Handbrake Transcoding (Software)

Handbrake Transcoding (Hardware)

The newly added Handbrake benchmark leverages the CPU, integrated GPU, and discrete GPU if available to transcode video using likely the most popular transcoding tool around. As a much longer test, the TDP plays more of a factor here than on some of the previous results, and the Acer Nitro 5 does very well on this assessment. On pure CPU encoding, the Zen 2 cores can almost keep up with the much higher frequency Core i7-10750H. When using the integrated GPU built into Ryzen, performance is good, although not quite matching the Ryzen 7 4700U we tested in the Acer Swift 3, which despite the smaller TPD, offers a slightly larger iGPU. The GeForce GTX 1650 is faster again, if you need to transcode video in a hurry. Generally, the dedicated media blocks perform the job quicker, but not necessarily with the same quality as the software based encoder, which may factor into your decision on which one to leverage for a transcode job.

7-Zip

7-Zip Compression

7-Zip Decompression

The very popular open-source file compression utility 7-Zip includes a built-in benchmark, showing the compression and decompression rates in MIPS. The Ryzen 5 can’t quite hang with the Ryzen 7 4700U in compression, but the Zen 2 cores do very well in the decompression result.

Web Workloads

Measuring web performance is a factor of both the underlying hardware, as well as the browser, since most web workloads leverage scripting which is compiled just-in-time, so the browser plays a big factor in overall performance. To lock the systems to an even playing field, we have moved to the latest Chromium-based Microsoft Edge browser, and will be utilizing it going forward. We took the opportunity to move away from some of the older, outdated web tests, and are focusing on Speedometer 2.0, which is a DOM performance measurement from the Webkit team, and WebXPRT which is developed by Principled Technologies.

Speedometer 2.0

WebXPRT 3

 

Interestingly, the 6-core, 12-thread Acer Nitro 5 was able to surpass the 8-core, 8-thread Ryzen 4700U in Speedometer, even with a small frequency deficit. WebXPRT, which really favors higher turbos and fast turbo activation, did not do as well on this system.

Storage Performance

The Acer Nitro 5 review unit shipped with a 256 GB Western Digital SN530 drive, which is a PCIe 3.0 x4 NVMe drive. The Acer also offers an additional M.2 port, as well as a 2.5-inch SATA slot for additional expansion. As a low-cost device, the 256 GB drive is small, but adequate when you consider the rest of the internals, and expansion is possible, either via internal drives, or of course USB-based storage to hold a gaming library.

The PCMark 10 storage test uses traces of actual workloads to provide an overall resulting score, and is more useful than a straight up bandwidth test of the drive.

The drive itself, despite being installed in a low-cost device, holds up well against other devices we have tested that cost much more. A larger drive in a gaming system would be nice, due to the massive size of game installs in 2020, but a 256 GB system drive is still welcome since it is pure NVMe SSD.

    The screen is such a big compromise on a laptop. I wish there was an option to pay a bit more and get something decent.

    I know it's kind of weird, but this looks like it would make a decent HTPC. It has lots of power and a new GPU for media playback.

    Yeah this screen makes it DOA to me. Such a shame they cut that corner as it really separates a decent laptop from a great laptop. Reply

    Seriously, 61% sRGB? How on earth do you even FIND an IPS display with primaries that far off?! Reply
  • Otritus - Friday, October 9, 2020 - link

    I recall an entry level laptop with amd having a 38% sRGB 60hz 1080p 15.6 in screen. That's more inaccurate than not! Reply

    Consumers need to realize that panel type ≠ inferred quality

    Very high quality TN panels have good enough color reproduction, but still not great viewing angles.
    Very poor quality IPS panels look like garbage, and look like garbage at any angle.

    Just to be clear I don't mean to let Very poor quality TN panels off the hook either.

    Very poor TN panels have extremely awful color reproduction, but are also combined with atrocious viewing angles that invert colors inside of 50cm viewing distances.

    So, as awful as this IPS panel is, it's still infinitely better than an equally very low cost/quality TN panel.

    I just got an laptop for less than $780. To my surprise, its IPS display has no backlight leaks even in the dark. I won't mention the brand because some of you may start the politic bullshit but here's the specs:
    Ryzen 4700U, 16GB DDR4 RAM, 512GB PCIE SSD, 14" 1080p 100% sRGB display, fingerprint sensor on the power button and backlit keyboard.

    The companies behind those brands that allowed to sell in the US must've thought that most consumers are pretty stupid - all their midrange and budget devices are garbage.

    I bought an Intel version of this laptop last year - paid $550, so it was the lowest end model and I'm certain had this same display. The screen isn't that bad - much better than other laptops I had looked at. In fact, I had originally purchased an HP budget gaming laptop on black Friday, but the TN screen was so horrible I had to return it. By comparison this screen was awesome. I'm real picky about screens - my normal driver is a Dell Mobile Precision with an expensive color calibrated display. This screen was not as good, but I have no problems with it. Reply

    I wish that the 1650ti version was available for testing as well. I've seen a few comparison benchmarks online, but not as rigorously done as these.

    Also, it looks like the 4800h version with the 1650ti and improved screen might be a decent foundation for a long term machine. Being able to add a 2.5 inch ssd as a boot drive, and then get two fast NVME drives to raid together to hold the game files, you could have a convincing mobile machine for the new titles coming out for the next console generation. It would be able to keep up with the higher data throughput demands, have 8 real cores, and a similar amount of memory, just no ray tracing.
