[PCPER] Bulldozer at ISSCC 2011 - The Future of AMD Processors

AMD at the ISSCC 2011
Date: Feb 23, 2011

The more I read about Bulldozer, the more impressed I am becoming. 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. 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. 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. 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. We are getting perilously close to the very limits of IPC (instructions per clock) with current technology and designs. 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. Where AMD could have an advantage over Intel are in several specific categories.

Fetch, decode, L2 cache, and a beefy floating point/SIMD unit are all shared. Since the majority of CPU work is integer based, AMD has implemented two complete integer units per CPU module.

At this year’s ISSC, AMD presented several papers on the Bulldozer architecture. These cover in depth about a handful of features that the new core will bring to AMD’s lineup. The first portion is essentially a refresh of what information we have been given last fall about the overall architecture of the Bulldozer core. The second looks at the changes in the schedulers which feed the integer execution unit. The final paper covers the power saving techniques.

The unit officially supports SSE3, SSE 4.1, SSE 4.2, AVX, and AES.
So this means it's better at what exactly?

As of 8 hours ago I made a comment saying I would be more interested in Bulldozer and the 990FX motherboards if it had SLI support.

I retract my statement because as of this afternoon I saw a friend of mine build an AMD rig with 1100T and Tri-Fire 6970's and I was blown away how much it cost him and how well it performed.

So... COME ON BULLDOZER! SHOW ME WHAT YOU GOT! tongue.gif

Are all 3 cards seeing 100% GPU useage?

I've read the article and it says that theoretically intel should still be better in light single threaded applications at the same clocks. Meaning amd should release higher clocked CPU at the same price range to counteract that. What seems to be really impressive from my point of view is the power saving tech.

For me: if AMD can get the same performance/price range + better power saving and favorably CHEAPER chipsets then it would be a one way trip for me to red side.

I looking forward to making my first system, but I'm prioritizing power consumption since the electric bill is pretty high as it is for me living on my own. I was aiming at SB but the sata fiasco really set me back a lot.

Not sure wasn't paying much attention. I was too busy looking at the FPS tongue.gif

A 2500K would be awesome. But I want to see what Socket 2011 (or 1356 have we any idea which is the enthusiast socket yet?) can do.

However we're going off track tongue.gif I really can't wait to see how Bulldozer will perform now.
