NVIDIA Partners Quietly Launch GeForce RTX 3060 with 8GB (128-bit) Memory

NVIDIA’s add-in board partners today began quietly launching the GeForce RTX 3060 8 GB, a variant of the RTX 3060 with a third of its memory size and memory bus-width sawed off. The RTX 3060, NVIDIA’s best-selling desktop graphics SKU from the RTX 30-series “Ampere,” originally launched with 12 GB of GDDR6 memory across a 192-bit wide memory bus, which at its reference speed of 15 Gbps (GDDR6-effective), makes 360 GB/s of memory bandwidth. The new variant comes with 8 GB of GDDR6 memory across a narrower 128-bit memory interface, with the same 15 Gbps data-rate, which works out to 240 GB/s memory bandwidth.

Besides memory size, bus-width, and bandwidth; NVIDIA hasn’t tinkered with the core-configuration with the RTX 3060 8 GB. It still comes with 3,584 CUDA cores across 28 SM, which work out to 112 Tensor cores, 28 RT cores, 112 TMUs, and 48 ROPs. The GPU’s base frequency is set at 1320 MHz, and boost frequency at 1777 MHz—same as the original RTX 3060. Even the typical graphics power is unchanged, at 170 W. The new 8 GB variant doesn’t replace the original, but is being positioned a notch below it, possibly to compete against the likes of the Radeon RX 6600 (non-XT), and perhaps even the Arc A750.
