AMD released its RX 6000 graphics cards a few months ago, but next-generation cards based on the new RDNA 3 architecture are, of course, in the works. Leaker KittyYuko (via Wccftech), who had a successful streak with Ampere and Big Navi leaks, shared some information about the upcoming Navi 33 GPU.
The cryptic tweak says that Navi 33 equals Navi 21, plus a next-gen IP core. That points to an RDNA 3 core with specs equal to the current Navi 21 GPU.
Variants of Navi 21 are inside the RX 6900 XT, 6800 XT, and 6800. The top-end chip inside the 6900 XT features 80 compute units, 80 RT cores, and 5,120 shaders, and according to KittyYuko, the next-gen Navi 33 GPU will feature the same specs. A patent from last year, however, shows that AMD may be using a chiplet design inspired by Ryzen processors, which would put two GPU cores next to each other for a total of 160 compute units and 10,240 shaders.
In general performance, AMD has seen gen-on-gen improvements of about 50% from GCN to RDNA, and from RDNA to RDNA 2, so it would make sense to see twice the compute units, RT cores, and shaders in AMD’s next-gen cards.
The improvements could be much greater, though. Next-gen RX graphics cards are rumored to be manufactured on TSMC’s 5nm process node, and they could provide as much as a 2.5x uplift over the current-gen design. AMD hasn’t formerly unveiled RDNA 3, but AMD executive vice president Rick Bergman and CEO Dr. Lisa Su have both confirmed that the company is hard at work on it. Bergman stressed the performance-per-watt improvement RDNA 3 will bring, saying it’s “a big focus” for AMD.
Originally, we expected RDNA 3 graphics cards in late 2021 or early 2022. However, Twitter user @Kepler_L2 suggests the cards won’t come until later in 2022. It could take even longer depending on the 5nm supply available to AMD. The semiconductor shortage is still gripping the world, and executives from companies like Intel suggest that it will take a few years for supply chains to fully recover.

 A Texas jury has ordered Intel to pay $2.18 billion in damages for infringing two patents. The lawsuit was filed by VLSI Technology LLC, a 4-year-old firm that Intel says has no products and no sources of revenue besides patent litigation. The two patents focus on methods for minimizing the power consumption of computing chips. One way to do this is by varying the system voltage: setting a higher voltage when high performance is needed, then lowering the voltage to conserve power afterward. VLSI's other patent focuses on altering clock frequencies as a power-saving technique.

Sounds like Intel's SpeedStep technology, first introduced in 2005, and predates the patents, which were issued in 2012 and 2010 respectively. Based on the success of this case, presumably VLSI also plans to sue AMD for Cool'n'Quiet, which was introduced in 2002. Trying to understand the jury's thinking on judgement in this case of what appears, at least on the surface, to be a blatant display of patent trolling. |

 The top Navi 21 GPU features 80 Compute Units which translates to 5120 Cores. However, these new reports suggest that the Navi 31 GPU will actually feature a multi-chiplet design, with each chip featuring 80 CUs. That means the top Navi 31 graphics card will have a total of 160 Compute Units, a whopping 10240 Cores, which is twice as much as Navi 21.
...
In fact, the new RDNA 3 architecture looks to be based on an MCM design. There’s a lot to unpack about what this means in terms of GPU performance, but the gist of it is that MCM designs will provide far better yields for performance as it combines multiple chiplets into one single package, rather than using a single large monolithic die.

 At CES, Razer debuted a new reusable N95 respirator called Project Hazel. Razer claims Project Hazel will use active disc-type ventilators, filtering air that’s breathed in, as well as the CO2 that’s being exhaled. The company adds that it will be certified to filter 95 percent of airborne particles, including the COVID-19 virus and other common pathogens. Microphones and amplifiers embedded in the ventilators will project your voice through the mask, so you won’t have to worry about sounding muffled. Of course, this wouldn’t be a modern Razer product if it didn’t support Chroma RGB LEDs. Razer envisions that each Project Hazel mask will include a large charging case that sterilizes the mask with UV light when it’s not in use.
I am definitely getting one of these if and when they put in production.
