Steamroller is a microarchitecture under development by AMD to succeed Piledriver in the second half of 2013.[2]

In 2011, AMD mentioned (by name) a third-generation Bulldozer-based line for 2013,[3] with working title Next Generation Bulldozer, on the 28 nm manufacturing process.[4] On 21 September 2011, leaked AMD slides indicated this third generation of Bulldozer core was codenamed Steamroller.[5][6]

Steamroller will still feature two core based modules found in Bulldozer and Piledriver designs.[2] The focus of Steamroller is for greater parallelism.[7] Improvements will center on independent instruction decoders for each core within a module, 25% more of the maximum width dispatches per thread, three ALUs per core,[8] better instruction schedulers, improved perceptron branch predictor, larger and smarter caches, up to 30% less instruction cache misses, branch misprediction rate reduced by 20%, dynamically resizable L2 cache, micro-operations queue,[9] more internal register resources and improved memory controller.

AMD estimates that these improvements will increase instructions per cycle (IPC) up to 30% while maintaining Piledriver high clock rates with decreased power consumption.[2]

Processors

AMD has confirmed it will not update the FX series Socket AM3+ or new socket version of a Steamroller based CPU in 2014.[10][11] An unconfirmed article citing anonymous sources with knowledge of AMD's internal roadmap extending into the 2015, also did not mention plans for a new FX processor.[12]

AMD's server roadmaps show only a four-core Steamroller Berlin APU and up to 16-core Piledriver-based Warsaw CPU in 2014.[13]

APU lines

There are two main APU lines announced:

Kaveri A-series APU
  • Desktop budget and mainstream markets (FM2+): The Trinity/Richland APU line is scheduled to be replaced by the Kaveri APU line as the third generation A10, A8, A6, and A4 series for the desktop market in February 2014.[14]
The new APUs will feature two to four enhanced Steamroller B cores and a GCN 1.1 Volcanic Islands GPU.[15] Reports have also claimed it will feature both a DDR3 and GDDR5 integrated memory controller, although it appears that both memory types cannot be used together.[16] Kaveri APUs will utilize the new FM2+ socket and will not be backwards compatible with previous generation FM2 motherboards.[17]
  • Known models are: A10-7850K with 4 cores at 3.7ghz, 512 stream processors and 4mb Lv2 cache.
  • Notebook mainstream and performance markets (Indus platform): The same as described in the desktop budget / mainstream markets. The FCH chipset will be codenamed Bolton.
Berlin APU
Enterprise and server markets: The Berlin APU will be similar to Kaveri, featuring four Steamroller cores, up to 512 stream processors, and support for ECC memory.[18]
