A barrage of leaks over the past few months left little to the imagination once it came time for AMD to officially unveil its Radeon 300 series graphics cards. Regardless, AMD filled us in on all of the pertinent details moments ago during its E3 press conference. (Editor's note: For Radeon Fury launch details, go here).

It starts with the entry-level R7 360 featuring 768 stream processing units (12 compute units), a GPU clock speed of up to 1.05GHz, memory bandwidth of up to 112GB/sec and a 128-bit GDDR5 memory interface with 2GB of GDDR5 RAM on tap. It carries an MSRP of $109, AMD said.

The next rung on the ladder is the R7 370, a slightly beefier offering with 1024 stream processing units (16 compute units) that’s clocked at up to 975MHz. Cards will come equipped with either 2GB or 4GB of GDDR5 memory featuring a 256-bit interface and up to 179.2GB/sec of memory bandwidth. Expect to pay around $149 for the opportunity.

The new R9 category, meanwhile, consists of the R9 380, R9 390 and the R9 390X.

The R9 380 packs 1792 stream processing units (28 compute units) with a clock speed of up to 970MHz. Buyers will also get 4GB of GDDR5 memory, a 256-bit memory interface and 182.4GB/sec of memory bandwidth. Pricing is set at $199, we’re told.

AMD’s R9 390 ups the ante with 2560 stream processing units (40 compute units) and a clock speed of up to 1,000MHz. It includes double the memory at 8GB of GDDR5 and a 512-bit interface with memory bandwidth of 384GB/sec. You’ll need to shell out $329 if you’re interested.

Last but not least (excluding the Fury X) is the R9 390X. This card includes 2816 stream processing units (44 compute units) with a clock speed of up to 1,050MHz. It, too, carries 8GB of GDDR5 VRAM and a 512-bit interface for a total memory bandwidth of 384GB/sec. AMD is tacking on an extra hundred bucks over the R9 390 for a total price of $429.

All of the “new” R9 cards (again, excluding the Fury X) are built on a 28-nanometer process, are air-cooled and support DirectX 12, Mantle, OpenGL 4.5, Vulkan and OpenCL 2.0 APIs. As was widely speculated, they are all indeed rebranded R200 series cards with higher core / memory clock speeds and additional VRAM.

AMD said its R7 and R9 300 series cards will hit select retailers on Thursday, June 18. It’s also worth mentioning that some retailers have been selling the cards a bit early so you may be able to snag one today if you look around hard enough.
