Nvidia Announces the RTX 4090, 4080 (16 GB and 12 GB), and More
At Nvidia's GPU Technology Conference (GTC), the company announced its first "Lovelace" GPUs for consumers: the RTX 4090 ($1600), RTX 4080 16 GB ($1120), and RTX 4080 12 GB ($900). The graphics cards are made with TSMC's N4 process, and support AV1 encoding and DLSS 3 upscaling.
The RTX 4090 comes with 24 GB of GDDR6X VRAM, and launches on October 12. Performance of the 4090 should be at least 60-70% higher than the RTX 3090 Ti, or higher in some cases (raytracing performance should be better than doubled). However, Nvidia is claiming up to quadruple the performance when using DLSS 3, which will not be made available on RTX 20/30-series GPUs due to an apparent requirement of fourth generation Tensor Cores and a newer version of "Optical Flow Accelerator". The new version of Deep Learning Super Sampling (DLSS) can generate entire frames, similar to video interpolation.
The RTX 4080 variants differ in both core counts and VRAM capacity, leading to a significant performance gap between them, and will launch sometime in November. The 4080 16 GB has nearly 27% more CUDA cores and 46% higher memory bandwidth than the 4080 12 GB. The GPUs also use different dies (AD103 and AD104). This could lead you to believe that Nvidia has turned the xx70-class card into a "4080" in order to sell it at a higher price.
Nvidia also announced the Jetson Orin Nano, a system-on-module capable of 20-40 trillion operations per second, starting at $200. CNX Software has a table showing order-of-magnitude improvements in some cases over the Jetson Nano and Jetson TX2 NX.
Nvidia has cancelled its DRIVE Atlan SoC for ~2025 driverless cars, replacing it on the roadmap with a more powerful "DRIVE Thor" SoC with 2 petaflops of floating point inference performance (FP8).
AMD will announce its Radeon RX 7000 graphics cards on November 3.
NVIDIA Reveals its Next-gen Chipset for Autonomous Vehicles
[...] NVIDIA says that Drive Thor can unify all the various functions of vehicles — including infotainment, the digital dashboard, sensors, parking and autonomous operation — for greater efficiency. Vehicles with the chipset will be able to run Linux, QNX and Android simultaneously. Given the vast processing power that autonomous vehicle operations require, automakers can even use two of the Drive Thor chipsets in tandem by employing a NVLink-C2C chip interconnect technology to have them running a single operating system.
In addition, NVIDIA claims that the SoC marks a significant leap forward in "deep neural network accuracy." The chipset has a transformer engine, a new addition to the NVIDIA GPU Tensor Core. "Transformer networks process video data as a single perception frame, enabling the compute platform to process more data over time," NVIDIA says. It noted that the SoC can boost inference performance of transformer deep neural networks by up to nine times, "which is paramount for supporting the massive and complex AI workloads associated with self driving."
AMD unveiled its entry-level Mendocino series of laptop processors at Computex 2022. The company didn't provide much in the way of meaningful information and briefly talked about its power efficiency. Now, it has announced three new Mendocino processors, the Ryzen 5 7520U, Ryzen 3 7320U and Athlon Gold 7220U, manufactured on TSMC's 6 nm process node. They use a modified version of the Zen 2 cores and support LPDDR5 memory.
[...] The "U" Mendocino processors' names confirm that all three SKUs have a maximum TDP of 15 W, making them ideal for thin and light laptops. The Ryzen 5 7520U is a 4-core, 8-thread processor with base/boost clocks of 4.3/2.8 GHz. The Ryzen 3 7320U has the same configuration but reduces the base/boost clocks to 4.1/2.4 GHz. Lastly, the AMD Athlon Gold 7220U has 2 cores, 4 threads and a base/boost clock of 3.7/2.4 GHz.
Microsoft Pluton is confirmed to be in the 7020 series. All three of the APUs include Radeon 610M graphics with 2 RDNA2 compute units, one-third that of a Ryzen 5 6600U with 660M graphics. The 610M may be identical to the iGPU in Ryzen 7000 desktop CPUs, and it supports AV1 hardware decode and up to 4 display outputs (USB-C ports with DisplayPort capability could be used to get close to this number).
You can see AMD's new mobile naming scheme at work. The third digit of 7520U indicates that it uses Zen 2 cores. We could see Ryzen 3 7340U and Ryzen 5 7540U "Phoenix Point" APUs using Zen 4 cores surrounding that model.

Facing never-ending criticism, NVIDIA has just announced it will not launch GeForce RTX 4080 12GB model, the card that we knew and will always know as RTX 4070. In a last-minute change in September, the company had decided to launch two RTX 4080 models with vastly different specifications. Turns out this has backfired hard.
NVIDIA has just announced it is 'unlaunching' its RTX 4080 12GB GPU. Only the 16GB model will be released. NVIDIA has confirmed that, 4080 16GB launches on November 16th.
