NVIDIA GeForce RTX 3090 and RTX 3080, here are the leaked specs
Shortly before the expected launch in September, the specs of NVIDIA’s upcoming RTX Ampere line were leaked from unspecified sources that disclosed them to VideoCardz. According to the website, three alleged GeForce SKUs will be launched in September: RTX 3090, RTX 3080, and RTX 3070.
The new line features major improvements: second generation ray tracing cores and third generation tensor cores made for AI and ML. As for connectivity and I / O ports, the new cards use the PCIe 4.0 interface and support the latest display outputs such as HDMI 2.1 and DisplayPort 1.4a.
NVIDIA GeForce RTX 3090 and 3080 in detail
The GeForce RTX 3090 comes with 24 GB of GDDR6X memory running on a 384-bit 19.5 Gbps bus. This feature is capable of providing a memory bandwidth capacity of 936GB / s. The card features the GA102-300 GPU with 5,248 CUDA cores running at 1,695 MHz and is rated for 350 W TGP (card power). While Founders Edition cards will use NVIDIA’s new 12-pin power connector, non-Founders Edition cards from partners such as ASUS, MSI and Gigabyte will be powered by two 8-pin connectors.
As for the specifications for the GeForce RTX 3080, we have a GA102-200 based card which has 4,352 CUDA cores running at 1,710MHz, coupled to 10GB of GDDR6X memory at 19 Gbps. The memory is connected to a 320-bit bus that achieves a bandwidth of 760 GB / s. The board is rated at 320W and is designed to be powered by two 8-pin connectors.
And finally, there is the GeForce RTX 3070, which is built around the GA104-300 GPU with an as yet unknown number of CUDA cores. We only know that it has the old GDDR6 memory (so not “X”) which runs at 16 Gbps on a 256-bit bus. The GPUs are allegedly manufactured with TSMC’s 7nm process, possibly using the EUV variant.
For the prices we will have to wait for the official launch and the announcements of the various partners.
