The cooling solution uses five heatpipes, which pass through the block that comes in contact with the GPU.

Here are photos of the PCB’s front and rear sides.

The capacitors used all over the PCB are polymers by FPCAP and APAQ.

The GPU205 follows the Blackwell architecture. Like its predecessor, it is manufactured by TSMC and uses a 5 nm production process. Its die size is 263 mm², and it has 31.1 billion transistors. It is pretty small, compared to the GPU203 which has a die size of 378 mm².

A 9-phase VRM handles the NVVDD and MSVDD power circuits and three phases handle FBVDD. A Monolithic Power Systems MP29816 controller controls these. For those who don’t know what these mean, NVVDD provides power to the GPU, FBVDD ensures the stability and accuracy of data transfers between the GPU and memory, especially at high clock speeds. In contrast, the MSVDD voltage manages the memory chips’ operation.

Two Alpha & Omega controllers handle the board’s power phases, for the GPU and its memory.

Alpha & Omega’s DrMos chips have the model number AOZ5310NQI and the marking DNNO. Their maximum continuous output current can reach 60A.

Samsung makes the GDDR7 memory chips. Their model number, K4VAF325ZC-SC28, indicates that they are rated for 28 Gbps. The RTX 5090 and RTX 5070Ti use the same memory chips, while the 5080 has higher-speed rated ones (32 Gbps).

The card’s power socket. Its type is 12V-2×6.

There is no information on the fan model numbers, but they most likely use rifle bearings, like the rest of the fans Galax uses in its GPUs.
