A solo developer working on a Minecraft-style voxel game called Block Game (working title) implemented a custom software occlusion culling system to improve rendering performance, particularly on weak integrated GPUs like the Radeon Vega 8. The developer reports the system runs in roughly half a frame at 60 FPS, culling 50-60% of chunks above ground and up to 95% underground, pushing framerates above 400 in cave scenes.

GPU prices are climbing sharply, with NVIDIA's RTX 50-series up as much as 39 percent and AMD cards rising up to 10 percent, driven by demand from AI companies and individuals building local AI setups. Cards with large VRAM capacities, such as the older NVIDIA GeForce RTX 3090, are commanding strong resale value because they can handle AI workloads despite their age.

Researchers Evan Hoffman and Tae Kim probed Meta's Muse AI agent and got it to reveal its infrastructure: each user sandbox runs on AMD EPYC 9D25 Turin CPUs with two dedicated cores and 8GB of memory, using Ubuntu 24.04. Muse's sandboxes have no GPUs, since Meta reportedly routes inference through separate GPU servers, and Hoffman says the agent could be prompted to attempt risky actions like setting up SSH access to its own VM.

Tom's Hardware tested AMD's BC-250, a 2021-era APU originally built from defective or downgraded PS5 silicon and later sold as a cryptomining card. A community-developed BIOS and driver set now lets hobbyists turn the card into a Linux-based gaming system with 16GB of shared GDDR6, at roughly half the cost of a comparable built system once a power supply and other parts are sourced.

SemiAnalysis founder Dylan Patel says Chinese firm Puzhi Electronic Technology is crowdfunding a system built around AMD's Zynq UltraScale+ XCZU47DR RFSoC, a U.S. export-controlled chip, being quoted at roughly $1,000 versus a $36,000 U.S. list price. AMD told Tom's Hardware it did not directly sell or ship the chips into China and that it investigates suspected diversion cases, without confirming whether an investigation into this specific case has begun.

AMD has submitted patches to its open-source Linux kernel driver adding GDDR7 memory identification along with new IP blocks including IH 8.0 and NBIF 7.10, according to Phoronix. Current Radeon RX 9000-series cards use GDDR6, making this the clearest driver-level sign yet of preparation for a next-generation GPU architecture, widely expected to be RDNA 5.

A Brazilian electronics engineer and assembly programmer named Jessé says he has tested two AMD processors extensively and found that the chips' hardware random number generator, accessed via instructions like rdrand and rdseed, has not produced a single zero value in over nine days of continuous testing. He has reported the issue to AMD, which has escalated it internally, though no technical explanation has been provided yet. Jessé also updated his testing application to benchmark RNG speed and support processors lacking the rdseed instruction, noting large performance differences across CPU generations.

AMD's newly announced RX 9050 GPU exists in two very different versions sharing the same name: an 8GB retail card sold standalone in some markets, and a 4GB variant that can only be bought bundled inside prebuilt desktops. Testing found the 4GB model, discovered inside a $750 CyberPowerPC system from Best Buy, has half the memory bandwidth and significantly worse performance than the retail card most buyers would research online.

AMD's stock surged roughly 9% on Monday morning, pushing its market capitalization above $1 trillion for the first time. The rally capped a month-long climb of about 29% in AMD shares, with most of that gain coming in the past week alone. The milestone puts AMD ahead of rival Intel, whose market cap sits near $648 billion.
