AMD Draws Bead on
x86 Core Innovation with Bobcat & Bulldozer
August
30, 2010
At
HOT CHIPS 22, AMD revealed new details on its two next-generation x86
processor core implementations, including AMDs unique approach to
high-performance, multi-threaded computing, as well as a sub one-watt
capable low-power design. The two new designs, codenamed “Bulldozer” for
high-performance PC and server markets, and “Bobcat” for low-power
notebook and small form-factor desktop markets, were designed from the
ground-up to address specific customer requirements and compute
workloads. The new cores are central to AMD’s future roadmap, including
the AMD Fusion Accelerated Processing Unit (APU) products and AMD’s new
high-performance server and client CPUs.
“In my opinion, Bulldozer and Bobcat are not only two of the greatest
technical achievements in AMD’s rich history, but two of the most
important for the industry as well,” said Chekib Akrout, senior vice
president and general manager, AMD Technology Development. “With CPUs
and APUs built from these core implementations, we expect our customers
to deliver a new wave of innovative PC form factors and high-performance
computing experiences.”
At HOT CHIPS 22, Brad Burgess, AMD Fellow and chief architect of Bobcat,
and Mike Butler, AMD Fellow and chief architect of Bulldozer,
presented at the “New Processor Architectures” session. The x86
architecture lies at the very heart of computing and AMD has
continuously evolved and improved its core designs. The Bulldozer and
Bobcat cores continue that evolutionary path and are designed to change
the user’s experience with the resulting products.
“Attacking both high-performance and low-power markets simultaneously
with two brand new architectures is an impressive accomplishment that
serves notice to the industry that innovation is alive and well inside
AMD,” observed Nathan Brookwood, research fellow at Insight 64.
Highlights of the new cores include:
Bulldozer
An
innovative approach to multithreaded compute performance that
balances dedicated and shared compute resources to provide a highly
compact, high core count design that is easily replicated on a chip
for performance scaling
New x86 instruction support (SSE4.1,
SSE4.2, AVX, and XOP including 4-operand FMAC)
Advanced power management features
Manufactured on advanced 32nm process
technology
Bobcat
Sub-one-watt capable operation
Out-of-order instruction execution for
higher performance
Estimated 90 percent of today’s mainstream
PC performance in half the area
Core power gating and a microarchitecture
optimized for low power
Highly synthesizeable design that moves
easily across manufacturing technologies
