AMD Radeon R9 380X Review: Fastest GPU Under $250
Introducing The Radeon R9 380X
As much as we all love uber-powerful, high-end graphics cards around these here parts, it’s in the more mainstream price segments where AMD and NVIDIA sell the bulk of their GPUs. Although AMD’s mid-range GPU line-up has been relatively strong for a while now, the company is launching the new Radeon R9 380X today with the goal of taking down competing graphics cards like the popular GeForce GTX 960.
The Radeon R9 380X may be a new member of the Radeon family, but it’s packing technology we’re already familiar with. Take a look at the specifications below and then we’ll dig into the rest of this story and explain...

The Radeon R9 380X has a fully-functional Tonga GPU with all 32 compute units / 2048 shader processors enabled (assuming 256-bits is the max width of the memory bus). AMD’s reference specifications call for a 970MHz+ engine clock with 4GB of 1425MHz GDDR5 memory (5.7 Gbps effective). Typical board power is 190W and cards require a pair of supplemental 6-pin power feeds. The vast majority of the Radeon R9 380X cards that will hit the market, however, will likely be custom models that are factory overlcocked and look nothing like AMD’s reference design.
The Sapphire Nitro R9 380X we received for testing is outfitted with an oversized, dual-fan cooler, with a few beefy copper heat-pipes and a dense heatsink array. The card is overclocked right out of the box as well.
The Sapphire Nitro R9 380X has a GPU engine clock of up to 1040MHz and 4GB of GDDR5 memory clocked at 1500MHz, for an effective data rate of 6Gbps. Memory bandwidth at that speed is up to 192GB/s, which is a nice bump over the reference card’s 182.4GB/s. Like reference cards, this Sapphire model requires a pair of supplemental, 6-Pin PCI Express power feeds.
Outputs on the card consist of a pair of DVI outs, an HDMI output, and a full-sized DisplayPort output. Of course, the Radeon R9 380X has full support for AMD’s Eyefinity multi-display technology, and it also supports FreeSync as well. Like newer Fiji-based cards, the GPU used on the Radeon R9 380X has an updated output segment that’s compatible with FreeSync / variable refresh rate technology.
