A new speed record for training NanoGPT was achieved in 39.9 seconds on an RTX 5090, representing a 46% improvement over the previous record through optimizations including sampled-softmax, FP8 quantization, and attention packing. The result was validated across 18 cold-cache runs with statistical significance (p=9.4e-10).
PNY reportedly denied a warranty claim for a melted RTX 5090 graphics card, asserting that damage from native PSU cables falls outside warranty coverage.
Wici Wireless announced an eGPU product claiming to deliver RTX 5060 Ti and 5090 performance over Wi-Fi 7 connectivity.
A PNY RTX 5090 graphics card's power connector melted while using a native PSU cable, but PNY rejected the warranty claim, stating only PNY-approved cables are covered. The incident highlights confusion from NVIDIA and board partners about which cables are safe for the RTX 5090, with conflicting guidance from PNY support.
Nvidia's GeForce RTX 5090 draws up to 647W power with DLSS 5 enabled, causing its 16-pin power connector to exceed 90°C—hotter than the GPU die itself. Testing by QuasarZone revealed the connector temperature jumped significantly when DLSS 5 was activated, raising concerns about reliability given existing reports of connector failures across high-end graphics cards.
BEACON is a GPU-based search for large prime gaps that discovered a record-breaking gap of 59,724 with merit 42.5192, surpassing the previous record of 41.9388 from 2017. The search used four RTX 5090 GPUs and a sophisticated algorithm combining sieving, prediction, and symmetric testing to identify twenty-two gaps that entered the Prime Gap List in September 2026.
