AMD is prepping two new power-efficient second-gen Ryzen CPUs, the Ryzen 5 2600E and the Ryzen 7 2700E.
The parts are aimed squarely at Intel Core ‘T'-suffixed series of microprocessors, which run at a standard TDP of 35 watts, and intended for platforms that require a standard x86 CPU, but in a more power-efficient platform with lower heat dissipation.
Both the Intel Core ‘T' and AMD Ryzen ‘E' CPUs are identical to their mainstream equivalents, except for the lower wattage and consequent lower clock speeds.
The Ryzen 2600E is the low-power counterpart to the Ryzen 5 2600X, AMD's fastest hexacore 12-thread part, which requires 95W and runs at a standard 3.6GHz and retails for around £200. The Ryzen 5 2600E, in contrast, is a 45W part but runs at a standard 3.1GHz.
The Ryzen 7 2700E, meanwhile, also requires 45W compared to 105W for the mainstream desktop part, and runs at a frequency of 2.8GHz compared to the full-fat Ryzen 7 2700X's 3.7GHz. However, the Ryzen 7 is an eight-core, 16-thread part.
Pricing, according to WCCFTech, will shadow Intel's ‘T'-series of CPUs.
The leaks, which have subsequently been confirmed, come after AMD in April launched similar low-power APUs with integrated Vega GPUs, intended for mobile devices.
Like the 'E'-suffixed Ryzens, the Ryzen 3 2200GE and Ryzen 5 2400GE chips boast a TDP of 35 watts, but also have AMD's Vega graphics integrated in the core.
The AMD Ryzen 3 2200GE and Ryzen 5 2400GE followed in the footsteps of the Ryzen 3 2200G and Ryzen 5 2400G, which pack the same number of cores and threads, along with integrated graphics, but at a much lower power consumption.
At the same time, AMD Epyc-based server CPUs have started rolling off the production lines in China, the product of its joint venture with Haiguang Information Technology.
Dubbed Dhyana and based on the Zen microarchitecture, the deal between AMD and Haigung required a fair degree of legal dexterity to pull off, both to remain within the bounds of AMD's x86 licensing agreement with Intel, as well as US technology export controls.
Intel, for example, was barred from selling Xeon CPUs into China in 2015 as a result of claims that they would be used in China's nuclear and military programmes.
According to Tom's Hardware, AMD stayed the right side of the line, legally, by establishing a joint venture in a company called THATIC, to whom it licensed x86 and other technology.
THATIC founded HMC and Haigung, with Haigung doing the design while HMC is responsible for manufacturing. With AMD holding a controlling 51 per cent stake in HMC, the company remains compliant with its x86 server-licensing obligations. It also holds a 30 per cent stake in Hygon. THATIC holds the remainder of the shares.
However, the Dhyana Epyc CPUs are bound solely for the Chinese market, with AMD benefiting from royalties on sales.
15 May 2018: AMD has launched upgraded Ryzen Pro microprocessors boasting Ryzen cores integrated with Vega graphics - what AMD used to call accelerated processing units or APUs. The parts are intended for corporate laptops and desktops, with the launch coinciding with new mobile and desktop systems from Dell, HP and Lenovo bearing the new CPUs.
However, despite their naming nomenclature, the new parts are based on first-generation Ryzen cores rather than the Zen+ microarchitecture that went into AMDs recent Ryzen 2 releases. As such, the office-oriented parts will lack the improved cache and memory latency of Ryzen 2, as well as the slightly faster clock speeds from being optimised to 12-nanometer, as opposed to 14nm, process manufacturing.
The parts encompass four desktop and three mobile offerings, all with four cores, but with the Ryzen 5 Pro 2400G, 2400GE, 2500U and Ryzen Pro 2700U coming with eight threads.
The parts are pitched at a lower price than Intel equivalents - from $169 to $349 - and, while sporting AMD's latest Vega graphics technology, they have dialled down the performance, partly to cut costs, but also to ensure that laptops don't meltdown under modest usage.
What makes AMD's ‘Pro' line-up of Ryzen CPUs different from standard Ryzen CPUs and APUs are the management features aimed purely at organisations. These include GuardMI, which offers memory encryption capabilities (like AMD's Epyc server CPUs), a secure boot mechanism, a firmware Trusted Platform Module supporting TPM 2.0.
In terms of the new hardware from major vendors - whose support AMD will need in order to crack the armlock Intel has on the corporate PC market - Dell has been showing off new Latitude 5495 laptops with 14-inch displays, as well as very corporate-looking Optiplex 5055 MT/SFF desktops.
HP and Lenovo, meanwhile, have launched a much wider range of laptops and desktops. In among the fairly standard looking hard is, in particular, the HP Elite Desk 705 Mini G4, which promises to be a space saver. Lenovo, too, has both an ultra-small 12.5-inch laptop and a slimline desktop, the Lenovo ThinkCentre M715q Tiny, which both look particularly interesting.
However, full details and specs have yet to be released.
