GPU Insanity – MSI RTX 5090 Lightning Z GPU Leaks

MSI’s RTX 5090 Lightning Z has leaked, and it is bonkers

MSI’s weather forecast predicted lightning at CES 2026, and now we know why. The company’s RTX 5090 Lightning Z GPU has leaked, with overclockers already setting new world records with it.

Yesterday, a world record 3DMARK Time Spy score was set by an overclocker called Dr.Antoine. Using an unknown MSI graphics card, a score of 53,207 was achieved. This was with an overclocked RTX 5090 GPU with reported GDDR7 memory speeds of 36 Gbps. Additionally, record Geekbench 5 and 3DMARK Port Royal scores were set by Lucky_n00b and oc_windforce, respectively, on HWBOT.

oc_windforce and Lucky_n00b released images of their RTX 5090 Lightning Z graphics cards. Since these GPUs were heavily overclocked, LN2 cooling was utilised. This means that we could not see the GPU’s stock cooling solution, only its PCB.

MSI’s RTX 5090 Lightening Z features dual 12V-2×6 power connectors and an insane 40-stage power design. Note that like all RTX 5090 GPUs, this model features 32GB of GDDR7 memory.

If you want the most overkill RTX 5090 on the market, this is it. This RTX 5090 is built for heavy overclocking, and we expect it to set many new world records over the coming days. We expect MSI to release more information about this new graphics card over the coming days.

OC3D will be at CES 2026, so we will likely see this new graphics card in person soon. If you want to see more CES 2026 news, stay tuned with OC3D.
