Global economy doubles in product every 15-20 years. Computer performance at a constant price doubles nowadays every 4 years on average. Livestock-as-food will globally stop being a thing by ~2050 (precision fermentation and more). Human stupidity, pride and depravity are the biggest problems of our world.

M2 has 35% faster iGPU than M1 after 18 months. Assuming +20% iGPU perf increase per year (+100% every 4 years), standard Apple MacBooks will have 40 teraflops iGPUs. Assuming that 20 teraflops is needed for 4K gaming, MacBooks will be capable of that in 2031. All with the same power consumption and price. Battery life will get longer, because of higher capacity batteries, so expect 40 hours battery life in 2032. I imagine that neural engine's performance will improve at a slightly faster rate and CPU's performance at a slightly lower rate. Interesting things are awaiting us. 2032 MacBooks will probably also feature 4K HDR webcams capable of recording in low-light conditions. Screens may also be 4Kish. It's remarkable how long it took for webcams to move from 720p to 1080p, I expected that to happen much sooner.

According to this SemiAnalysis report, "Intel 4" process is going to bring substantially lower density improvements than 2x compared to "Intel 7".

The newer benchmark you use in comparing CPUs or GPUs, the bigger difference you will see between older and newer ones.

For example between i3-10100 and i3-12100 there is 20% difference in Cinebench R15, 40% in Cinebench R20 and 50% in Cinebench R23.

Newer programs are better suited for newer architectures and instructions. But not every game and program is new or modern.

The First High-Yield, Sub-Penny Plastic Processor

It took a major redesign for cheap flexible chips to reach their promise

14 Jun 2022

For decades, hopeful techies have been promising a world where absolutely every object you encounter—bandages, bottles, bananas—will have some kind of smarts thanks to supercheap programmable plastic processors. If you’ve been wondering why that hasn’t happened yet, it’s that nobody has built working processors that can be made in the billions for less than a penny each.

It hasn’t been for want of trying; in 2021 Arm reproduced its simplest 32-bit microcontroller, the M0, in plastic, but even this couldn’t hope to meet the mark. The problem, according to engineers at the University of Illinois Urbana-Champaign and at British flexible-electronics manufacture PragmatIC Semiconductor, is that even the simplest industry-standard microcontrollers are too complex to make on plastic in bulk.

In research to be presented at the International Symposium on Computer Architecture later this month, the transatlantic team presents a simple yet fully functional plastic processor that could be made at sub-penny prices. The Illinois team designed 4-bit and 8-bit processors specifically to minimize size and maximize the percentage of working integrated circuits produced. Eighty-one percent of the 4-bit version worked, and that’s a good enough yield, says team leader Rakesh Kumar, to breach the one-penny barrier.

“Flexible electronics has been niche for decades,” says Kumar. He adds that this yield study shows “that they may be ready for the mainstream.”

Turns out that M1 Ultra, despite all these transistors (the most on the market), is exceptionally good only in video editing and code compilation. In everything else it's worse than 12900K + 3090.

Arm unveiled new mobile CPUs and GPUs. Changes are significant and you can read about them in detail in the linked news articles. In short, the new CPU is 25% faster per core, 20% more efficient and the new GPU is 15% faster per core, 100% faster in machine learning and 300% faster in ray-tracing. The new Mali G715 cores support Variable Rate Shading and are currently the most efficient (I guess until new iPhones come out later this year). First products with next-gen APUs are expected early 2023 (for example Samsung Galaxy S23).

Intel’s Raptor Lake to Support Both DDR4-3200 And DDR5-5600

By Josh Norem on July 6, 2022 at 11:23 am
https://www.extremetech.com/computing/3 ... -ddr5-5600
Intel’s Alder Lake spearheaded the company’s efforts to turn the tide against AMD. It was successful too, earning praise similar to “Intel is back” from many reviewers. Now that Alder Lake is in the history books, the company now turns to its successor, Raptor Lake. It will be an enhanced version of Alder Lake, as Intel is using its famous tick-tock strategy again. Despite the similarities between the two architectures, one lingering question was whether or not Intel would continue to support DDR4 memory. It did so with Alder Lake, but that launched last year when DDR5 memory was almost non-existent. It has now been confirmed that Intel will indeed support both memory types on its upcoming platform. The news comes from a leaked slide Intel showed to sales teams in China.

The slide was posted by a Twitter uses named @9550pro and it lays out in tidy detail what to expect from Intel’s upcoming Raptor Lake-S platform. Support for DDR4-32oo is unchanged from Alder Lake. Still, it wasn’t clear if Intel would drop it in order to get people to adopt DDR5 instead. The fact that it’s keeping it around for one more generation is good news for upgraders on a budget. It will also help Raptor Lake appeal to more people than if it removed DDR4 support. On the DDR5 side of the equation, the news here is it’s upping the frequencies a bit. Alder Lake maxed out at DDR5-4800, but it will supports speeds up to 5600 on Raptor Lake. It also notes there are “additional PCIe 4.0 lanes for the chipset” but it doesn’t say how many.
