NVIDIA has reportedly resumed the production of the GeForce RTX 3080 12GB after a roughly two-month-long halt. This particular SKU was launched during the crypto-madness without an official MSRP and a street price of over $1,000. However, since the end of the Ethereum boom, it has been going for as low as $749 (just $50 more than the vanilla 3080).

Both the variants of the RTX 3080 feature the GA102 die but the 12GB model comes with a wider 384-bit bus (320-bit on the 10GB). This pushes the bandwidth all the way up to 912GB/s (vs 760GB/s on the 10GB). In addition to this, the 12GB model also packs two additional SMs or 256 cores. At 4K, the RTX 3080 12GB performs very similarly to the RTX 3080 Ti, especially in memory-bound workloads.
