Xiaomi Mi 11 Ultra review

Introduction

Now that the Pro moniker has gone mainstream, it’s Ultra that has come to represent the cream of the crop, and the Xiaomi Mi 11 Ultra can wear that badge proudly. Limited to its home market last year, the ultimate Mi has gone global this time around, and we’re happy to have it for review today.

We’re torn whether it’s the camera system’s physical appearance that is more striking or the hardware inside. A simply massive raised area on the back looks bolted on, almost after the fact, it’s hard to miss, and it’s a great conversation starter even if it’s not everyone’s cup of tea.

But its size is warranted – the main camera packs the largest sensor used on a modern-day smartphone, and next to it – two more modules unmatched in their own fields, in one way or another. Oh, and yes, there’s also a display here – because why not, but also because it can be useful.

There’s a lot more than 1.1 inches of OLED on the front. The 6.81-inch Super AMOLED is all kinds of great – high resolution, high refresh rate, high brightness, HDR, a billion colors, you name it. Meanwhile, the Snapdragon 888 underneath is second to none as chipsets go this year and with 256GB of base storage, should we even mention the lack of expansion capability as a con?

Misc: Fingerprint reader (under display, optical); NFC; Infrared port.Xiaomis don’t normally have dust and water protection, but that’s changed this year with the Mi 11s – both the Pro and the Ultra have an IP68 rating, and that’s a most welcome development. Conversely, a staple of the brand’s handsets, both affordable and expensive, the IR emitter remains. Stereo speakers have been making their way to the Xiaomi midrange, so it’s only natural that the high-end models have them, and these have been tuned by Harman/Kardon, that couldn’t hurt.

An increase in battery capacity compared to last year’s model is another upgrade we can appreciate. On the other hand, they did downgrade the charging – instead of the Mi 10 Ultra’s 120W, you only get 67W here. Tsk-tsk.

Xiaomi Mi 11 Ultra unboxing

The packaging has lost the flair of the Mi 10 Ultra’s presentation, and the Mi 11 Ultra showed up in a standard black box with copper lettering (or is it rose gold?). What’s inside that?

Our EU-bound retail bundle includes the 67W charger – that’s not the case in all markets with chargers coming as a free-of-charge option in some places (China, maybe other parts of Asia). It’s a proprietary adapter with a USB-A output, so it won’t please USB PowerDelivery die-hards. There is a USB cable included too.

A headset may be missing, but there is a USB-C-to-3.5mm dongle included so you can use your own. Also inside the box is a transparent soft silicone back cover. While the (free) protection is appreciated, the look and feel of the thing is no match for the phone itself.

Oppo A95 5G is official with 6.43″AMOLED display, Dimensity 800U

Oppo A95 5G popped up on China Telecom’s website earlier this month and today, the phone maker made the device official. The Oppo A95 5G has the same chipset and screen as the Oppo Reno 5Z, but one fewer cameras on the back.


Oppo A95 5G

The panel on the front is a 6.43” AMOLED with a punch hole in the upper left corner. The resolution is Full HD+ and the panel has a standard 60Hz refresh rate. The A95 5G is powered by Dimensity 800U chipset by Mediatek and has 8GB RAM to keep it company. The storage is either 128GB or 256GB, with micro SD for up to 2TB more.

The camera setup on the back includes 48MP main, 8MP ultrawide and 2MP macro modules. The front-facing shooter is 16MP. Oppo did not put anything spectacular where the depth cam was – just a mere “48MP” sign.

The battery has 4,310mAh capacity with 30W fast charging through the USB-C port. The connector is on the bottom, right next to the 3.5mm audio jack. Other highlights include ColorOS 11.1, based on Android 11, Wi-Fi 802.11a/b/g/n/ac and Bluetooth 5.1 support.

The Oppo A95 5G is offered in Black, White and Dawn Blue on the company website. It is up for pre-order and costs CNY1,999 ($310/€255) or CNY2,299 ($355/€295), depending on the storage choice.

Lenovo P620 Threadripper Pro 3975WX Review

AMD’s Threadripper consumer HEDT processors continue to be praised strongly for their excellent compute performance and connectivity options. But what if you want more than 256GB of memory? What if you want your RAM to run in 8-channel mode? What if you want more than 64 PCIe Gen 4 lanes? Well… that’s where Threadripper Pro comes in.

Primary Specifications:

  • 32-core AMD Threadripper Pro 3975WX processor
  • 128GB of 3200MHz ECC DDR4 memory in 8-channel mode
  • AMD Radeon Pro W5700 graphics card with 8GB GDDR6 VRAM
  • WD SN730 256GB NVMe SSD
  • 1kW 80Plus Platinum PSU

We are examining the Lenovo ThinkStation P620 workstation that is built around Threadripper Pro and its 8-channel memory support. There are a few options for the base processor on Lenovo’s website including 12, 16, 32, and 64 core options. Specifically, we are looking at the 32-core Threadripper Pro 3975WX chip and we are hoping that Lenovo can keep it running at the rated 3.5-4.2GHz speeds beneath that modestly sized CPU cooler.

Partnering this 280W TDP monster with its 128 PCIe Gen 4 lanes is 128GB of 8-channel DDR4 3200MHz ECC memory. While a 128GB installation is merely small-fry for Threadripper Pro, the 3200MHz modules running in 8-channel mode should allow for some excellent results in bandwidth-intensive tasks. Plus, you get a 1600MHz Infinity Fabric link for the Zen 2 cores.

I will, however, emphasise my dislike for Lenovo decision to deploy a 40mm fan and shroud to cool each DIMM bank. This seems unnecessary for a 128GB installation and merely adds additional noise and points of failure. Metal heatspreaders on the DIMMs would have been better, if enhanced cooling is deemed necessary.

Graphics comes in the form of an 8GB Radeon Pro W5700 blower-style card which we have already reviewed on KitGuru. That makes this an all-AMD system as far as the key components go. Another key benefit is ISV certification for the Lenovo P620. That point will be music to the ears of system buyers in a business environment with users who run software on the guaranteed support list.

Another point that will garner particular attention from prospective buyers is the display output connectivity. On its ‘pro-grade’ card, AMD deploys five Mini-DisplayPort 1.4 connections and one USB-C port. That gives you convenient access to six total display outputs which is super. As highlighted in our review of the Radeon Pro W5700, you can power five 4K monitors or three 5K alternatives, making this an excellent workstation proposition.

Lenovo uses its own WRX80 motherboard to house the sWRX8 Threadripper Pro CPU. The power delivery solution looks competent and Lenovo’s use of proper finned VRM heatsinks with passive cooling is to be commended. Six total PCIe Gen 4 slots are provided by the motherboard – four x16 bandwidth and two x8. However, only two x16 slots remain usable due to the slot spacing, and the top one will likely interfere with the RAM fan’s header.

It is actually disappointing to see Lenovo offering up sub-par expansion slot capability. There is no clear way to use the 128 lane capability from Threadripper Pro. That is especially disappointing to users who will want multiple graphics card alongside high-bandwidth networking and storage devices. However, the limited expandability is a clear compromise from Lenovo’s use of a compact chassis with just a couple of 80mm fans for intake and exhaust airflow.

At least you do get dual, cooled M.2 slots on the motherboard. One of those is occupied by a 256GB WD SN730 SSD in our install. Clearly, most users will want to adjust the storage configuration. But this is clearly a very subjective requirement, so I respect Lenovo for offering a basic, cheap drive for the baseline configuration.

Power is delivered by a 1kW 80Plus Platinum unit. Lenovo highlights 92% efficiency on the configurator page, but this is likely a mistake for 230/240V UK customers given the more stringent 80Plus Platinum requirements for those operating voltages. The PSU’s tool-less design is absolutely superb and works very well; a single connector port feeds power from the unit through the motherboard where it is then distributed accordingly, including via break-out cables for PCIe and SATA connectors.

Connectivity for the system is just ‘OK‘. You get 10GbE Aquantia AQC107 networking onboard, but a secondary network adapter is disappointingly omitted. I would have liked to see a few more USB ports on the rear IO, including some in Type-C form and preferably 20Gbps high-speed rated. However, the front IO is excellent with four 10Gbps USB connections, two of which are Type-C. I also appreciated the system’s included audio speaker when using the unit without a proper set of speakers.

The chassis build quality is good and feels very well-built given its compact form. Man-handling the hefty system is easy thanks to the front handle. And the internal tool-less design is excellent. Lenovo’s configurator gives an option to upgrade to a side panel with key locking to prevent unauthorised access, which is good to see.

With that said, cooling certainly looks to be limited with just two 80mm intake fans on the chassis. The graphics card, CPU, PSU, and (annoyingly) RAM also have fans to take care of their own cooling. If you are thinking of adding a second high power GPU, though, the internals are likely to get very toasty.

Priced at around £5.5-6K inc. VAT in the UK (depending on the graphics card situation given current shortages), we are keen to see how Threadripper Pro performs in this reasonably compact workstation.
