MSI R7 370 Gaming 2G
Pitcairn apparently refuses to retire. MSI’s R7 370 Gaming 2G comes in 100MHz higher than its R7 270 Gaming 2G predecessor’s gaming mode.
It also becomes apparent that the manual overclocking limit is similar to the older models. Both the Sapphire HD 7850 Dual-X with 2GB GDDR5 and the HIS R7 270 IceQ X² Turbo Boost Clock end up with a clock rate of 1150MHz.
The actual performance increase is well below what the specifications would suggest, since the high stock frequency is significantly above Pitcairn’s sweet spot.
The memory is supplied by Samsung again. It’s clocked at 1425MHz, which is a marginal improvement over the MSI R7 270 Gaming 2G’s 1400MHz GDDR5. We were able to get it to 1500MHz, but any more than that resulted in marginal stability.

GPU-Z shows the best possible version of the small Pitcairn GPU that still makes sense.
The processor can be cooled fairly easily by the relatively powerful thermal solution. It’s too bad that this small version of Pitcairn is all that’s under the hood. An AMD Radeon R7 370X would have been a better option for this launch.
The heat sink under the slightly modified cover has a relatively simple design. It consists of three 6mm heat pipes, aluminum fins and a body made of a single block. That’s all that’s really needed, though.
MSI opts not to include a back plate. This is really no loss. If anything it’s an acceptable cost-cutting measure. It’s easy to see from the bottom that the voltage regulators aren’t cooled at all. This is puzzling for a graphics card that turns off its fan at idle or low loads. We’ll see the consequences of this decision when we get to our infrared temperature measurements.
In its third generation, the graphics card still has one 6-pin power connector, which is still completely sufficient.
The sink’s fins are arranged horizontally, which makes sense considering the single-block cooler and low amount of waste heat. With this setup, some of the dissipated thermal energy is exhausted out the back of the slot panel.
Once again, there’s exactly one UEFI BIOS to be found. The DVI-I connector provides an analog signal, whereas the second DVI connector is exclusively digital. There’s also an HDMI and a DisplayPort connector.
