HP Elite t655 Thin Client is a compact PC with Ryzen Embedded

Thin Clients are typically compact, low-power, low-performance computers that don’t need a lot of horsepower, because their primary purpose is to connect to a remote server that’s doing all the real work.

But sometimes the lines get blurry, and it’d be easy to mistake the upcoming HP Elite t655 Thin Client for a full-fledged desktop computer. After all, it supports up to 32GB of RAM, up to 512GB of storage, and has an AMD Ryzen processor. But HP is positioning this compact, fanless system as a thin client and it will most likely end up in offices rather than homes.

There are a few reasons for that. First, it has an AMD Ryzen Embedded R-series processor rather than one of AMD’s more mainstream chips. That may not really be that much of an issue since Ryzen Embedded chips aren’t all that different from the processors AMD designs for laptops and desktops… except that they often lag behind in terms of performance.

In this case, the fact that the HP Elite t655 Thin Client ships with a 45W power supply suggests that you should expect laptop-class performance at best.

Second, HP’s thin client officially Windows 10 IoT Enterprise LTSC or the Linux-based HP ThinPro 8.0 operating systems. The company doesn’t sell its thin clients with Windows, Ubuntu, or other desktop-class operating systems.

But folks have been successfully installing Windows, Ubuntu, and other desktop operating systems on thin clients from HP and other companies for years. So while the HP Elite t655 may not be designed for home use right now, it might be worth keeping an eye out for used models on eBay or at garage sales in the coming years.

HP says the Elite t655 Thin Client measures 200 x 200 x 35mm (about 7.9″ x 7.9″ x 1.4″) and weighs 1.3 kg (2.9 pounds). It supports up to three 4K displays, supports DDR4-3200 memory, and comes with up to 64GB of eMMC flash storage or up to a 512GB of PCIe NVMe SSD.

There’s optional support for a wireless card with WiFi 6 and Bluetooth 5.2 support, and has a standard set of ports that includes:

  • 1 x USB 3.1 Gen 2 Type-A
  • 1 x USB 3.1 Gen 1 Type-C
  • 3 x USB 3.1 Gen 1 Type-A
  • 2 x USB 2.0 Type-A
  • 3 x DisplayPort 1.2
  • 2 x 3.5mm audio jacks
  • 1 x Gigabit Ethernet jack

HP also includes a modular port section that can be used to add an HDMI or VGA port, additional USB ports, or other features.

The HP Elite t655 Thin Client is expected to be available in August, 2022 and pricing should be available closer to then.

The new HP Elite c640 G3 Chromebook is a business-class Chromebook with a 14 inch display, enterprise security features, a 5MP webcam, AI-based noise reduction capabilities, support for WiFi 6E and optional support for 4G LTE.

And so is the new HP Elite c645 G2 Chromebook. The difference is that the first model is powered by a 12th-gen Intel processor, while the latter has an AMD Ryzen chip inside.

The Intel model is available with Intel Celeron, Pentium, Core i3, Core i5, and Core i7 processor options, while the AMD version comes with unspecified Ryzen 3, 5, or 7 chips.

And while most specs are the same for both models, the Intel version features two Thunderbolt  4 ports. On the AMD versions, the equivalent ports are USB Type-C ports that lack Thunderbolt certification.

Both models also have HDMI 2.0 USB Type-A, and 3.5mm ports plus microSD card readers. Optional security features include a fingerprint sensor, smart card card reader, and HP Sure View Reflect display (which makes it difficult for folks to spy on your display by limiting the viewing angles). There’s also a privacy shutter for the webcam.

Both laptops are available with up to a 1920 x 1080 pixels touchscreen or non-touch display, up to 16GB of LPDDR4x memory (soldered and not user upgradeable), and storage options that include 64GB of eMMC flash storage or a 128GB, 256GB, or 512GB SSD.

Both also have MIL-STD 810H tested cases with aluminum lids that incorporate recycled aluminum.

The HP Elite c640 G3 Chromebook with Intel processor options is expected to go on sale in mid-May for $509 and up, while the AMD-powered HP Elite c645 G2 will hit the streets in June for $559 and up.

They’ll join the previously announced HP Elite Dragonfly G3 Chromebook, a premium thin, light and powerful model that was expected to launch in April, but which HP now says is coming in early summer 2022 for $1,149 and up.

What we can learn from the Tuskegee Syphilis Study, 50 years later

For 40 years, researchers deceived test subjects about the true purpose of the study.

This year marks the 50th anniversary of The New York Times' exposé of the infamous Tuskegee Syphilis Study, thanks to a frustrated social worker who tipped off the press. By the time it broke in 1972, experiments had been conducted on unsuspecting Black men in the area surrounding Tuskegee, Alabama, for 40 years. All 400 or so of the male subjects had contracted syphilis, and all had been told they were receiving treatment for the disease—except they were not.

The researchers in charge of the study instead deliberately withheld treatment in order to monitor the progression of the disease as it advanced unchecked. The study's exposure led to a public outcry and heated debate over informed consent, ultimately giving rise to a number of regulations to prevent such an ethical lapse in the future. The Tuskegee Syphilis Study has since become a vital case study in bioethics, but public awareness of its existence is spotty at best. A new paper published in the American Journal of Respiratory and Critical Care Medicine seeks to remedy that, and it argues that federal regulation is not enough to prevent similar unethical research.

"Citizens have an obligation to remember the victims of any major catastrophe, as people do with 9/11," the paper's author, Martin Tobin, told Ars. "The men in Tuskegee suffered major injury, including death, at the hands of the premier health arm of the US government. A failure to remember what happened to these men is to add another layer of injury to what they already endured."

Lenovo’s new Slim laptops delight the digits with carbon and glass

Lenovo plays with textures and high-end parts for a new range of ultralight clamshells.

On Thursday, Lenovo introduced a series of laptops with various options and designs. The Slim laptops, formerly called IdeaPad Slim, are a new lineup of clamshell designs that will look to compete in June with thin and light builds, high-end components, high-res OLED displays, and some unique textures.

Creator clamshells

The Slim 7 Pro X and Slim 7i Pro X have 2 Thunderbolt 4 ports, USB-A, a headphone jack, and HDMI 2.0.

The standout products are the 14.5-inch Slim 7i Pro X and Slim 7 Pro X—with the "i" meaning it has an Intel CPU. Lenovo is launching the "X" moniker to represent laptops made for creators. In addition to offering up to an RTX 3050 laptop GPU (4GB GDDR6), Lenovo also fine-tunes the machines' hardware, a Lenovo rep told Ars Technica when we checked out the laptops in person. AI software also helps manage performance and battery usage.

Lenovo wouldn't disclose TDP numbers but said the Slim 7/7i Pro X has a higher TDP than the non-Pro X versions, (which in the US will only be available as 16-inchers), especially if you get it with a dedicated laptop GPU, which is turned down in the non-Pro X versions.
