New GeForce RTX 3050 variant offers the same performance but lower power use


Nvidia’s GeForce RTX 3050 is no one’s idea of a powerhouse, but it’s a decent 1080p GPU and it’s still the cheapest way to buy into Nvidia’s RTX 3000-series ecosystem if you want DLSS 2.0 support or Nvidia’s ray-tracing implementation. MSI has published specs for a revised version of one of its RTX 3050 GPUs (via VideoCardz), advertising the same general features and performance levels but lowering the power consumption estimate by 15 W.

The lower power consumption appears to come from the GPU’s use of a smaller graphics die, called GA107. Older RTX 3050s use the same GA106 die as the RTX 3060 series, but with many of that die’s 3,840 CUDA cores switched off. This can allow Nvidia to reuse partially defective GA106 dies, but as chip yields improve and the number of defective dies decreases, it either means shipping fewer RTX 3050s or putting perfectly good chips in cheaper GPUs. The GA107 die includes a maximum of 2,560 CUDA cores, and it apparently needs a bit less power than a GA106 die with the exact same number of cores enabled.

The two MSI cards in question otherwise have almost exactly the same specs, power consumption aside: an 1807 MHz boost clock, 14 Gbps of memory bandwidth thanks to GDDR6 on a 128-bit memory interface, and 2,560 CUDA cores. One other change is that the newer revision has two DisplayPorts and two HDMI ports, rather than three DisplayPorts and one HDMI port, a small change that most likely has nothing to do with the GPU change. Another is that the card now requires a 6-pin power plug, rather than an 8-pin plug.

Slightly lower power use is a good thing, but this new RTX 3050 card still requires up to 115 W of power, which is well above the 75 W max amount of power that can be provided to any expansion card through a PCI Express slot without requiring an extra power connector. GPUs without a power connector are vanishingly rare, but they’re still of interest for people upgrading a super-small PC or a cheap box from HP or Dell with a low-capacity power supply and no 6- or 8-pin power connector.

Usually, these quiet GPU refreshes eventually become the default configurations, and older revisions are phased out over time as supplies dry up—this has happened with the “lite hash rate” (LHR) versions of RTX 3080 and 3070 GPUs, the GDDR6 version of the GTX 1650, and the RTX 2060 with 12GB of RAM instead of 6GB, among others. We’d expect this to happen with the RTX 3050, eventually, but for now expect most cards to continue using the partially-disabled GA106 die.
