The AMD refresh lineup

So, as you guys know AMD has been respinning their GPUs quite a bit, the oldest one is 3 years old, the Hawaii GPU as reviewed today actually already has been with us ever since late 2013, you know it as the GPU used in the Radeon R9 290 and 290X. For a quick refresh here's an overview.

  • The Hawaii GPU used on the Radeon R9 290X is now used in the Radeon R9 390X but rebranded to Grenada. This series is positioned against the GeForce GTX 970 and 980.
  • The R9 285 is Tonga, which is to be the R9 380, this chip will now be renamed to "Antigua" and is positioned against the GeForce GTX 960. Tonga/Antigua does offer Direct3D feature-level 12_0 support.
  • The Radeon R7 270 series (First Pitcairn (aka Radeon 7800 released three years ago) then called Curacao) will be the 370 series tagged as Tobago. The 260 (Bonaire) is gonna be the 360 series. And so on.
  • The one new chip is of course Fiji, it will get two SKUs, based on a Pro and XT GPU model. We expect a liquid cooled version, and likely a lower clocked less specced Pro model with air-cooling of some sort. Probably just one SKU will launch initially though.

R9-370 (previously the R7870 GHz / Pitcairn XT)

  • Stream Processors 1024
  • Clock Frequency up-to 975 MHz
  • 2 TFLOPS compute performance

  • API - DirectX 12 / OpenGL 4.4 / Mantle

As stated, the R7-370 is based off Pitcairn Pro, you guys know this GPU as Radeon HD 7850. AMD bakes the GPU on a 28nm node, in very simple wording that means they can put more transistors on a smaller processor die area, typically resulting in less power consumption as well. The Radeon Pitcairn graphics core has a good 2.8 Billion transistors. Memory wise the R7-370 card in it's reference design will pack either 2 or 4 Gigabyte of DDR5 memory. The memory bus is 256-bit, but combined with the GDDR5 memory (which is quad data rate) you do get a decent chunk of much needed memory bandwidth, which the GPU certainly can use. The memory clock will be 1400 MHz, being quad data-rate (GDDR5) that results in an effective data rate of 5600 MHz or 5.6 Gbps. This will give the graphics card 179 GB/sec of framebuffer bandwidth to do its thing in. The GPU packs 2.8 billion transistors,has 64 TMUs and 32 ROPs.
