Nvidia's Rubin CPX GPU, initially designed for AI tasks, may actually contain graphics-specific hardware blocks like Raster Output Pipelines and display engines, leading to speculation that it could lay the groundwork for the next-gen RTX 6090. The die shot of Rubin CPX reveals 16 Graphics Processing Clusters and 256 Raster Output Pipelines, potentially offering significant performance gains over the RTX 5090. If repurposed for gaming, Rubin CPX could deliver around 28,672 CUDA cores and 224 ROPs, indicating a notable performance uplift. The inclusion of a 512-bit memory bus, GDDR7 support, and PCIe 6.0 hints at the possibility of Rubin CPX being a stepping stone for future GPU advancements. The release of Rubin CPX is expected at the end of 2026, with the RTX 6090 possibly being announced at CES 2027.

SpaceX says it is going to begin manufacturing GPUs — $1.75 trillion IPO listing reportedly includes in-house GPU production

SpaceX's confidential $1.75 trillion IPO filing reveals plans to manufacture its own GPUs, investing billions in internal processor production due to a lack of long-term supply agreements with silicon suppliers. The company's intention to build GPUs, not specialized AI accelerators, is highlighted, with the naming convention still uncertain. While SpaceX's CEO confirmed plans for high-volume semiconductor manufacturing, the specifics of the GPUs remain unclear, raising questions about potential competition with existing AI GPU manufacturers like AMD and Nvidia. The S-1 form's confidential nature prevents verification of its content, leaving room for speculation on SpaceX's semiconductor endeavors.

Tests show $30,000 AI GPUs are terrible password crackers — RTX 5090 gaming GPU outperforms Nvidia H200 and AMD MI300X

Tests show $30,000 AI GPUs are terrible password crackers — RTX 5090 gaming GPU outperforms Nvidia H200 and AMD MI300X

Tests conducted by Specops revealed that expensive $30,000 AI GPUs like Nvidia's H200 and AMD's MI300X performed poorly compared to consumer graphics cards like Nvidia's RTX 5090 in password cracking. Despite the significant price difference, the RTX 5090 outperformed the other GPUs by 20% over the MI300X and 63.7% over the H200 on average. The RTX 5090 excelled due to its design with more INT32 cores, which are crucial for password cracking, while the AI GPUs prioritize different instructions for their machine learning tasks. This study underscores that consumer desktop GPUs remain the most efficient for password cracking tasks.

Bain Capital's data center unit removes disgraced tenant suspected of smuggling Nvidia GPUs to China — Megaspeed previously alleged to have spent roughly $2 billion on AI processors for illicit distribution

Bain Capital's data center unit, Bridge Data Centers, has terminated its contract with Megaspeed International in Malaysia amid suspicions of smuggling Nvidia AI accelerators to China. The move reallocates power capacity to cloud provider Zenplayer, indicating a shift away from companies under investigation for illegal activities. This decision aligns with the heightened scrutiny of high-end computing hardware flows between the U.S. and China. As Bridge Data Centers seeks additional capital for expansion, maintaining compliant and stable tenants becomes crucial for securing funding in the competitive regional data center market.

Corsair's Strix Halo AI Workstation 300 gets even more expensive amid the RAMpocalypse — Ryzen AI Max 395+ flagship now sits at $3,399

Corsair's Strix Halo AI Workstation 300 prices have surged, with the Ryzen AI Max 395+ model now at $3,399 due to the ongoing RAMpocalypse. The top-end variant with 128 GB of RAM and 4 TB storage has seen a significant price increase. The escalating costs are attributed to the current component shortage exacerbated by geopolitical tensions. Despite the price hikes, these figures are in line with market rates for similar high-end systems. Other models like the Beelink GTR9 Pro and GMKtec Evo X2 offer comparable specs but at slightly lower prices.
