Gunnir unveiled its top-end Intel Alchemist card closer to the start of this year - and this week the Chinese company has started selling a white edition of the Arc A770 Photon 16G OC graphics card. It has been reported that this is a world first - no other Alchemist card on the market features a custom cooler finished in white. Gunnir's standard Photon OC model - fitted with a dark gray-ish triple-fan design - has been available for a few months, and a snazzy blue Flux OC model also exists but is restricted to 8 GB VRAM.

Regardless of color choices, Gunnir's range topping Photon OC cards feature the best mainstream graphics hardware that Team Blue has to offer - namely an Alchemist SKU as seen in the (reference design) Arc A770 Limited Edition 16 GB model. Intel's board partners are having a tough time shifting their Arc lineup of graphics cards - discerning customers are wary of relatively immature architectures - and Gunnir has chosen to introduce a seasonal price cut across the Alchemist range. The promotion offers Chinese customers (via Gunnir's JD.com store) discounts on A380 (max. 33%), and A770 (max. 13%) GPUs.

Ansys announced it is collaborating with GF to deliver innovative, unique, and feature-rich solutions to solve some of the biggest challenges facing data centers today. With data being generated at a record pace, causing a surge of power consumption in data centers globally, there is an ever-increasing need for innovative solutions to accelerate data transmission while optimizing energy efficiency. To meet such rising demands, GF is focused on developing groundbreaking semiconductor solutions that leverage the potential of photons—instead of electrons—to transfer and move data, maintaining GF's position as a leader in the rapidly growing optical networking space.

GF Fotonix is GF's next generation, widely disruptive, monolithic platform. GF Fotonix is the first in the industry to combine its differentiated 300 mm photonics and RF-CMOS features on a silicon wafer, delivering best-in-class performance at scale. "Our engagement with Ansys is another example of how GF is partnering with the ecosystem leaders to deliver innovative, time to market solutions for our customers," said Mike Cadigan, senior vice president for Customer Design Enablement, GF. "By coupling GF Fotonix with Ansys' industry-leading simulation solutions, we are reaching new levels in photonic chip design. With support for Verilog-A simulation and process-enabled custom design, designers have greater modeling capabilities to meet their performance, power, and density requirements."

Optical computing has been the research topic of many startups and tech companies like Intel and IBM, searching for the practical approach to bring a new way of computing. However, the most innovative solutions often come out of startups and today is no exception. According to the report from EETimes, optical computing startup Lightelligence has developed a processor that outperforms regular GPUs by 100 times in calculating some of the most challenging mathematical problems. As the report indicates, the Photonic Arithmetic Computing Engine (PACE) from Lightelligence manages to outperform regular GPUs, like NVIDIA's GeForce RTX 3080, by almost 100 times in the NP-complete class of problems.

More precisely, the PACE accelerator was tackling the Ising model, an example of a thermodynamic system used for understanding phase transitions, and it achieved some impressive results. Compared to the RTX 3080, it reached 100 times greater speed-up. All of that was performed using 12,000 optical devices integrated onto a circuit and running at 1 GHz frequency. Compared to the purpose-built Toshiba's simulated bifurcation machine based on FPGAs, the PACE still outperforms this system designed to tackle the Ising mathematical computation by 25 times. The PACE chip uses standard silicon photonics integration of Mach-Zehnder Interferometer (MZI) for computing and MEMS to change the waveguide shape in the MZI.

Intel Labs recently opened the Intel Research Center for Integrated Photonics for Data Center Interconnects. The center's mission is to accelerate optical input/output (I/O) technology innovation in performance scaling and integration with a specific focus on photonics technology and devices, CMOS circuits and link architecture, and package integration and fiber coupling.

"At Intel Labs, we're strong believers that no one organization can successfully turn all the requisite innovations into research reality. By collaborating with some of the top scientific minds from across the United States, Intel is opening the doors for the advancement of integrated photonics for the next generation of compute interconnect. We look forward to working closely with these researchers to explore how we can overcome impending performance barriers," said James Jaussi, senior principal engineer and director of the PHY Research Lab in Intel Labs.

During its GPU Technology Conference (GTC) in China, Mr. Bill Dally—NVIDIA's chief scientist and SVP of research—has presented many interesting things about how the company plans to push the future of HPC, AI, graphics, healthcare, and edge computing. Mr. Dally has presented NVIDIA's research efforts and what is the future vision for its products. Among one of the most interesting things presented was a plan to ditch the standard electrical data transfer and use the speed of light to scale and advance node communication. The new technology utilizing optical data transfer is supposed to bring the power required to transfer by a significant amount.

The proposed plan by the company is to use an optical NVLink equivalent. While the current NVLink 2.0 chip uses eight pico Joules per bit (8 pJ/b) and can send signals only to 0.3 meters without any repeaters, the optical replacement is capable of sending data anywhere from 20 to 100 meters while consuming half the power (4 pJ/b). NVIDIA has conceptualized a system with four GPUs in a tray, all of which are connected by light. To power such a setup, there are lasers that produce 8-10 wavelengths. These wavelengths are modulated onto this at a speed of 25 Gbit/s per wavelength, using ring resonators. On the receiving side, ring photodetectors are used to pick up the wavelength and send it to the photodetector. This technique ensures fast data transfer capable of long distances.

Today, at Intel Labs Day, Intel highlighted industry-leading technological advances toward the realization of the company's long-standing vision of integrating photonics with low-cost, high-volume silicon. The advancements represent critical progress in the field of optical interconnects, which address growing challenges around the performance scaling of electrical input/output (I/O) as compute-hungry data workloads increasingly overwhelm network traffic in data centers. Intel demonstrated advances in key technology building blocks, including miniaturization, paving the way for tighter integration of optical and silicon technologies.

"We are approaching an I/O power wall and an I/O bandwidth gap that will dramatically hinder performance scaling. The rapid progress Intel is making in integrated photonics will enable the industry to fully re-imagine data center networks and architectures that are connected by light. We have now demonstrated all of the critical optical technology building blocks on one silicon platform, tightly integrated with CMOS silicon. Our research on tightly integrating photonics with CMOS silicon can systematically eliminate barriers across cost, power and size constraints to bring the transformative power of optical interconnects to server packages." -James Jaussi, senior principal engineer and director of PHY Lab, Intel Labs.

Mozilla is announcing that the latest version of its Firefox browser, Firefox 57, is just too good for just another numbered release. The improvements under the hood are so great, they say, and the performance improvements over previous Firefox releases are so grand, that only one name would have been enough to convey this message. That's why the latest Firefox release has been christened "Firefox Quantum".

Mozilla are saying their new Firefox Quantum browser delivers 2x the score in Speedometer as their previous Firefox 56. The new, refined browser didn't appear overnight, though; it's seen numerous improvements under the hood through the application of the Goldilocks principle to browser design, straddling an approach between increased performance and acceptable memory usage. Multi-process and optimized memory footprint are part of the secret sauce, but a new, super-charged CSS engine written in Rust goes a long way. Prioritization of the open tab also helps this increased speed, while (Mozilla says) reducing memory utilization by 30% when compared to Chrome.
