Fortunately, both AMD and Intel seem to have settled on an answer that should allow them to take advantage of ballooning transistor counts to gain additional performance: The company has sworn off the quest for 4GHz, shied away from clock speed as a measure of performance, and utterly rewritten its CPU roadmap. So the dual-core Opteron is large, but it’s also a very close match for Intel’s “Smithfield” dual core, which weighs in at roughly million transistors and mm 2 , although estimates and methods of counting transistors can vary. The folks there are also quick to remind anyone who will listen that AMD was first to tape out an xcompatible dual-core design and first to demonstrate such a beast in public. Dell returns to the stock market after six years. And if I do use it will it hurt the overclockability of the processor or Benchmarking? Remove Advertisements Sponsored Links.

In order to be able to post messages on the Overclock. To do so, the company tweaked its fabrication process, using lower-leakage transistors that switch somewhat slower but waste less power, among posernow things.

A pair of Opteron processors.

In fact, AMD says that the Opteron was designed from the outset with dual-core implementations in mind. AMD’s dual-core design is something more than just a pair of CPUs glued together on a single piece of silicon, and this design choice yields a performance dividend.

The chips will include all of the latest enhancements AMD has made to the K8 core, including SSE3 support and an improved memory controller with broader compatibility, improved memory loading, and more efficient memory mapping. We also have a head-to-head battle of single-socket, dual-core workstation processors: However, instead of incrementing the tail end of the model number by two as clock speeds ramp up, as the Opterons, and did, the dual-core models will come in increments of five.

The only requirement is that the motherboard must be able to support newer 90nm chips like the Opteron The most widely noted example of ad problems, by far, has been at the company Moore co-founded.

Voldenuit It’s nice of Krogoth to fill in for Chuckula over the holidays. The newer version with 2MB of L2 cache has million transistors.

About us Privacy policy Mailing list Mobile. This is one of the minor miracles of choosing thread-level parallelism over higher clock speeds. Keep reading to see how the new Opteron stacks up against its Opteron predecessors and against Intel’s latest “Nocona” Xeons. CPU designers have nearly exhausted their collective bag of tricks to get more performance out of additional transistors on a chip by increasing parallelism at the powrenow level.

Speculative execution and deep pipelining are by now very standard features, and CPU designs are getting increasingly complex and hard to manage. Please enter your desired user name, your email address and other required details in the form below.

Try it, and you’ll see. The folks there are also quick to remind anyone who will listen that AMD was first to tape out an xcompatible dual-core design and first to demonstrate such a beast in public. However, there poowernow some overlap. Originally Posted by Jimmy Question.

The even better news for current owners of Opteron systems is that the dual-core Opterons will be pin-compatible with existing Socket systems, capable of acting as drop-in replacements for current single-core models. They’re cosmetically identical, save for the slightly revamped model numbering scheme. Register Now In order to be able to post messages on the Overclock.

LG HU85L projector needs but two inches to cast a 90″ picture.

When you’re not optimizing for the absolute best linear performance, he noted, many things are possible, including everything from changing the oxide thickness and transistor voltages to resizing buffers and more extensive clock gating.

Two years later, the same processors are available at 2.

If you do not want to register, fill this field only and the name will be used as user name for your post. Peter Norton is actually a practicing amv, and if you unscramble the letters in the word “Symantec”you come up with “evil idiot”. The higher models will carry a premium, but AMD plans to bring the prices of dual-core Opterons down over time into the territory of the current single-core models.
