NVIDIA is introducing two graphics cards based on the PG132 reference board design, which is Geforce RTX 3090, and Geforce RTX 3080. Both graphics cards will also be available with NVIDIA Founders Edition. – The RTX 3080 Founders Edition with PG133 bord design and RTX 3090 FE Graphics card with PG136 board design.
Both reference boards have been photographed and we can take a closer look at the differences between the Graphics cards board.
The main difference between This Two Geforce RTX 30 series graphics cards is the lack of an NVLink multi-GPU connector. Only the Geforce RTX 3090 graphics card has support for dual-GPU configurations.
Another distinctive feature is the lack of two frontal memory GDDR6X modules on the Geforce RTX 3080 Graphics cardboard. The RTX 3090 has dual-sided memory modules, which means a total of 24GB each memory module has 1GB. The Geforce RTX 3080, on the other hand, only has 10 memory modules. A variant of Geforce RTX 3080 with 20GB memory is also planned, but based on the information from AIBs, this variant will debut after Big Navi. Recently we spotted NVIDIA next-gen Quadro RTX Ampere Graphics card with a huge 48GB of GDDR6 memory.
Both Graphics cards feature dual 8-pin power connectors by default, but there are some changes to the components. It seems that The Geforce RTX 3080 has lost two power stages compared to Geforce RTX 3090. We also counted 6 capacitors missing from the Geforce RTX 3090 Graphics card.
As you might notice, even the Geforce RTX 3090 GPU board does not have all the power stages and capacitors installed. This board might also be used for other cards in the future, such as TITAN Ampere GPU.
