AMD's Bulldozer architecture at ISSCC 2011
Intel's latest Sandy Bridge architecture rules the CPU roost right now despite suffering from a motherboard chipset issue, but does AMD have what it takes to challenge their huge rival?آ The company has used the recent ISSCC 2011 conference to publish more details about their next-generation Bulldozer architecture to give us some clues about what they have (with every pun intended) in the pipeline.
The more I read about Bulldozer, the more impressed I am becoming.آ AMD has barely been able to keep up with Intel for the past 6 years, which is disappointing considering the success they found with the original Athlon and then Athlon 64.آ Since Intel introduced the Core 2 series, AMD has only been able to design and sell processors that would sometimes achieve around 90% of the overall performance of Intel’s top end processors.آ AMD also suffered from die size and performance per watt disparities as compared to Intel’s very successful Core 2 and Core i7/i5/i3 processors.آ The latest generation of Sandy Bridge based units again exposed how lacking in overall design and performance AMD’s Phenom families of chips were.
Before we all go off the deep end and claim that AMD will surpass Intel in overall performance, we need to calm down.آ We are getting perilously close to the very limits of IPC (instructions per clock) with current technology and designs.آ It appears to me that with the Bulldozer architecture, AMD should reach parity with Intel and their latest generation of CPUs when it comes to IPC per core.آ Where AMD could have an advantage over Intel are in several specific categories.
