MSI R9 380 Gaming 2G
Tonga reloaded? MSI’s R9 380 Gaming 2G is practically identical to the R9 285 Gaming G2. The “new” version receives a meager 27MHz boost over the 285’s OC mode, which defaulted to 973MHz. It appears that the power target rises as well, which we’ll get to later.
The bottom line is that there’s barely any room for meaningful overclocking. The card maxes out at 1135MHz. An average of five to seven percent more usable performance is paid for with a virtual explosion in power consumption. Our measurements jump above 200W, which just isn’t worth it.
The memory is made by Samsung this time around, and its clock rate goes up a bit from the R9 285 Gaming 2G’s 1375MHz to 1400MHz. We were able to overclock it safely all the way to 1500MHz. Anything above that just wasn’t stable over longer time periods. Here’s an overview of the technical specifications:

Again, the data provided by GPU-Z doesn’t present us with any surprises. The changes from the graphics card’s predecessor are largely cosmetic in nature.
It’s too bad that Tonga XT with its 2048 shader units is an Apple-exclusive. AMD traded an immediate influx of money for the chance to give PC enthusiasts something new to talk about. This decision is now coming back to haunt AMD’s partners and customers outside of the Mac universe. More so than any other card introduced today, Tonga XT had the potential to make a splash.
The cooler found under the slightly modified cover is really just an update to the previous design rather than something new. However, the position of the heat pipes is changed so that there’s one central 8mm heat pipe and four additional 6mm heat pipes on the side.
The back plate is screwed to the card just like the one on its bigger sibling. It also serves the same function, which is to say that it looks nice and stabilizes the card’s PCB. Without thermal pads, it can’t help draw heat away from the board.
We can see from the bottom that the VRM is cooled by a flat plate that has to make do with the airflow that comes through the thermal solution above it.
The two 6-pin power connectors are familiar from AMD’s Radeon R9 285, but the 225W specification is now surpassed a bit during full load and stress test scenarios. The card stays well under this number during gaming, though.
The graphics card uses horizontal cooling fins, which makes sense for a cooler body that consists of a single block and not as much waste heat. Some of that thermal energy can be exhausted out the back of the I/O panel this way.
This graphics card also has a single UEFI BIOS. In contrast to its bigger sibling, there’s an analog signal coming from the DVI-I connector. But the second DVI connector is digital-only. In addition, there’s one HDMI and one DisplayPort connector.
