PlayStation's Mark Cerny says a version of FSR 4 could be implemented on the PS5 Pro
"Our target is to have something very similar to FSR 4's upscaler available on PS5 Pro for 2026 titles as the next evolution of PSSR," Cerny tells Digital Foundry. The PS5 Pro's PlayStation Spectral Super Resolution (PSSR) is a custom upscaling technology that lets the console run lower-resolution versions of games and make them appear like they're 4K, and by Cerny's own lengthy explanation, it was created using a combination of existing and future AMD tech.
Based on our review of AMD's new GPUs, FSR 4 is not a miracle worker. In some cases it leads to a lower frame rate than you might get from FSR 3, but in exchange for more detail. That extra crispness, while subtle, will probably make a difference to someone who's already spent $700 on a "Pro" console. The comparison video below does a pretty good job of illustrating the improvements FSR 4 actually makes:
Sony believes implementing FSR 4 on the PS5 Pro is even possible in the first place because the company also directly contributed to the development of the tech through its "Project Amethyst" collaboration with AMD. "The neural network (and training recipe) in FSR 4's upscaler are the first results of the Amethyst collaboration," according to Cerny.
The company's work with AMD was announced with a focus on building new machine learning architecture for game graphics, but it will clearly have more immediate impacts on PSSR and current PlayStation consoles, too. "FSR 4 and this next evolution of PSSR are a paradigm for our future," Cerny tells Digital Foundry, "going forward we expect to have our own implementations of each of the algorithms developed through the collaboration."

Wedbush: Nvidia, AMD China AI Deal a 'Bullish Catalyst' for Big Tech
Aug 14 - Wedbush is calling it a bullish sign for the AI sector. Nvidia (NASDAQ:NVDA) and Advanced Micro Devices (NASDAQ:AMD) are reportedly getting the green light to sell AI chips in China, provided they hand over 15% of profits to the U.S. government. According to sources, Nvidia will share revenue from its H20 AI accelerator, while AMD will do the same with its MI308 chips. Warning! GuruFocus has detected 5 Warning Signs with NVDA. Analyst Daniel Ives said this unusual arrangement removes a key growth barrier for the AI industry, with potential ripple effects for U.S. Big Tech leaders like Microsoft (MSFT), Palantir Technologies (PLTR), Alphabet (NASDAQ:GOOGL), Meta Platforms (NASDAQ:META), and Amazon (NASDAQ:AMZN). Ives noted that keeping the blockade on Nvidia's H20 would have been a gift to Huawei, potentially worth $15 billion annually, and a blow to U.S. competitiveness. He emphasized the U.S. now holds the edge in AI, a first in three decades but warned China's tech giants, including Alibaba (NYSE:BABA), Baidu (BIDU), Tencent (TCEHY), and Xiaomi (XIACF), are ramping up fast. The Middle East's AI push is another battleground, with Saudi Arabia and the UAE looking to U.S. firms for infrastructure and expertise. Wedbush sees the 15% fee as a small price for massive market access. This article first appeared on GuruFocus.

HP made a gaming PC for people who don't want to look like they own a gaming PC — meet the Omen 35L Stealth Edition
HP just announced the perfect gaming PC for me. The new HP Omen 35L Stealth Edition is a refreshed version of the HP Omen 35L I reviewed last year. In addition to updated internals, like the latest AMD CPU and Nvidia RTX 50-series GPU, this model has an all-black chassis, hence its 'Stealth' moniker. This might not seem like a big deal, but to me, it's a huge selling point. I got to see this desktop first-hand at a recent HP event and was immediately drawn to this mid-tower. RGB lighting has become synonymous with gaming, which is all well and good, but I wouldn't exactly call myself an RGB fan. I even turn all RGB lighting on my personal gaming rig at home. The Omen 35L Stealth Edition's nondescript design almost makes it appear like an average office PC, which I think is quite impressive. HP Omen 35L (Intel) HP Omen 35L (AMD) Price $1,499 $1,499 CPU Intel Core i5-14400F AMD Ryzen 7 7800X3D GPU NVIDIA GeForce RTX 5050 NVIDIA GeForce RTX 5050 RAM 16GB 16GB Storage 512GB 512GB Ports Top: 1x USB-C, 2x USB-A | Rear: 6x USB-A, 2x USB-C, 1x Ethernet Top: 1x USB-C, 2x USB-A | Rear: 6x USB-A, 2x USB-C, 1x Ethernet Dimensions 16.14 x 16.06 x 8.26 inches 16.14 x 16.06 x 8.26 inches Weight 31.9 pounds 31.9 pounds This PC doesn't just have visual appeal; it also boasts components powerful enough to play the best PC games. There's a wide range of configurations, with your choice of up to a 14th Gen Intel Core or AMD Ryzen 9 CPU and up to an Nvidia GeForce RTX 5090 GPU. Choices for RAM and SSD storage are also plentiful. Higher-end configurations will cost more, but the entry-level Omen 35L Stealth Edition starts at a relatively affordable $1,499. Like the previous Omen 35L, both the new model and the Stealth Edition will feature industry-standard parts, making it easier for you to upgrade or replace parts as needed. This was a big feature of the last Omen 35L, so it's great to see HP continue this trend. Both the standard and the Stealth Edition of the HP Omen 35L are expected to launch sometime in October. I gave the previous Omen 35L our Tom's Guide Editor's Choice award, so I have big hopes for its successor — especially the Stealth Edition.

Why Nvidia and AMD's China pay-to-play deal with Trump could backfire
Welcome to AI Decoded, Fast Company 's weekly newsletter that breaks down the most important news in the world of AI. You can sign up to receive this newsletter every week via email here. Why Nvidia's and AMD's China deal with Trump could backfire The companies making the most money from the AI boom are the ones selling the processors, such as Nvidia and AMD. On Monday those two chip giants cut a deal with the Trump administration that will allow them to sell their products into the China market. For Nvidia—the dominant provider of AI chips powering the generative AI boom—the agreement means that it can once again sell its H20 chip to Chinese developers. It's the latest chapter in a long saga. The Biden administration blocked the sale of Nvidia's most powerful AI chips to China in 2022, but deemed the sale of the less powerful H20 chip an acceptable national security risk. The Trump administration continued blocking sales of Nvidia's H200 and Blackwell chips. But in April, it went a step further by effectively blocking the sale of the H20 chips, too. The new deal shows that Nvidia CEO Jensen Huang's charm offensive in Washington, D.C., convinced the Trump administration that the U.S.'s technological, economic, and national security goals are best served when the world's AI models and apps are built to run on chips made by U.S.-based companies (like Nvidia). Or maybe the Trump Administration just wanted a piece of the action all along. The administration exploited its jurisdiction over export policy to extract a percentage of Nvidia and AMD's Chinese sales payable to the U.S. Treasury. 'I said, 'Listen, I want 20% if I'm going to approve this for you, for the country,'' Trump said during a press conference on August 12, describing his negotiation with Nvidia's Huang. He added that Nvidia negotiated the percentage down to 15%. That cut could amount to as much as $3 billion this year, given the high demand for the H20 chips. Trump's demand for 15% is something new in U.S. trade policy. 'The 15% take indeed sets a precedent,' Columbia Business School professor Lori Yue tells Fast Company. 'It may encourage other companies to adopt similar strategies, viewing profit-sharing as a work-around to government bans.' This could lead to a pay‑to‑play arrangement where only the richest corporations can afford to pay the government for permission to sell into a foreign market. Indeed, Treasury Secretary Scott Bessent hinted during a TV interview that the approach could spread to other products in other industries. The administration's tax will very likely translate into higher chip prices for Nvidia and AMD's Chinese customers, such as Tencent. The Chinese government has recently blasted Nvidia's H20 chips over security concerns, and the new 15% tax is likely to rankle Beijing even more. The Chinese government would like to see AI developers building their models and apps on top of AI chips from China-based Huawei. The Trump aAdministration may be driving some of Nvidia's Chinese customers to do just that, even if it requires rebuilding their infrastructure and tech stacks. Musk's Grok chatbot is making noise but falling behind Grok, xAI's chatbot, has had a rough week. The model that powers the Grok chatbot on X is Grok 4, which was announced July 9. At the time, xAI said the new model was the most intelligent one in the world. And the model did achieve state-of-the-art performance on several benchmark tests, including the superhard Humanity's Last Exam, on which it scored 25.4%, three points higher than Google's Gemini 2.5 Pro. As of August 11, the Grok chatbot is available free to all X users, even those on the free tier. In one sense, it marked an immediate improvement. The social platform's permissive environment has made it a clearinghouse for all kinds of misinformation and unsupported claims. Now far more people are using Grok to quickly fact-check those statements. But on August 7 OpenAI released its new GPT-5 model, which outperforms the Grok 4 models on many independent benchmarks. GPT‑5 shows state-of-the-art reasoning, math and coding skills, visual understanding, creative writing, and health-related question performance. However, GPT‑5 scored poorly on SimpleBench, ranking 5th behind Grok 4 and others in humanlike reasoning and social intelligence. While the benchmark results were circulating—and a GPT-5 backlash was growing—xAI CEO Elon Musk threatened to sue Apple for giving OpenAI's ChatGPT app the top ranking among free apps in the App Store (the Grok app ranks fifth). Must presented no evidence, appearing to simply be lashing out. And to make matters worse, Grok's problems with inappropriate content resurfaced this week. After being taken offline for spewing antisemitic rhetoric in July, the chatbot was again briefly taken offline Monday—this time for reasons not divulged by X. The chatbot had an opinion, however, telling one user that it had been taken offline after angrily stating that the U.S. and Israel's war on Gaza was a 'genocide.' One user demonstrated that after Grok had been turned on again, it no longer stated that Gaza should be classified as a genocide. During the 2024 presidential campaign, Donald Trump won the support of some tech billionaires, such as Marc Andreessen and Elon Musk, by promising to use a light-touch approach to regulating tech companies, including AI companies. Now Public Citizen is out with a report detailing the extent to which the administration has dialed back oversight and enforcement actions on the tech industry. In just six months with Trump in the Oval Office, the U.S. government has withdrawn or halted 47 of 143 federal enforcement actions against tech companies, the report states. At the start of Trump's second term, 104 technology companies faced 143 federal investigations and enforcement actions. The administration has withdrawn 38 actions and halted 9 others against 45 companies. Beneficiaries include eBay, Meta, Microsoft, PayPal, SpaceX, and Tesla. The report suggests that political spending generated returns through dropped prosecutions and policy changes. Tech corporations, executives, and investors spent $1.2 billion during the 2024 election cycle, including $863 million in donations to super PACs, $222 million in payments to Trump businesses, $76 million in lobbying efforts, and $25 million in inauguration donations, Public Citizen reports.
