Single CPU in Dual Operation: P4 3.06 GHz with Hyper-Threading Technology

Quote from the last page:

In real world situations the feel of Hyper-Threading is much better that our benchmarks actually show; this is why we also produced the video, which demonstrates this. Hyper-Threading is particularly beneficial when at least two applications are making heavy demands on the processor simultaneously. This can easily occur when you are archiving large amounts of data in the background, while working with your standard office applications in the foreground. Similarly, MPEG-4 encoding of a DVD film can be carried out, while at the same time e-mails can be edited with several browser windows open. One important conclusion for all hardware test magazines is that everyone must re-think test methodologies. Running just a single-threaded benchmark on its own does not represent real-world behavior anymore. THG has started working on this issue already, and our video gives you a little taste of what’s to come.

Let’s look at the situation from an overall perspective: with the introduction of the 3.06 GHz P4, Intel has distanced itself from the competition at AMD, still unable to supply its top model, the XP 2800+. In practical terms, this means that the XP 2600+ (2133 MHz) is the AMD product competing with the P4 3066 (3.06 GHz). The Athlon 2800+ was only able to match the 3.06 GHz P4 in a few areas: 3D rendering, Cinema 4D and SPECviewperf. The difference is particularly apparent with Sysmark 2002. Advanced users should note that the Athlon XP 2800+ only approaches the performance of the 2.8 GHz P4 when the Dual-DDR333 platform is used.

With the introduction of its Hyper-Threading technology, Intel has confirmed that constantly increasing the clock cycle is not the only way to skin the proverbial cat. In simple terms, Hyper-Threading means that the P4 processor is divided internally into two virtual CPUs, and recognized as a multi-processor configuration by the operating system. But watch out! If you want to use Hyper-Threading you need an operating system that actually supports multi-processor environments, such as Windows XP. Older versions like Windows 98 or ME will only recognize the new P4 as a standard CPU without HT.

Final Words
At the beginning of this year Intel had just introduced their 0.13-micron Northwood core at 2/2.2GHz and now, 10 months later, Intel has kept their promise of scaling up clock speeds faster than before as we finish reviewing their 3.06GHz Pentium 4. As you read this, Intel is sampling their 90nm parts, readying for a 2H-03 launch of the interim successor to the Pentium 4 - Prescott. Prescott will bring us a larger L2 cache, new instructions and it will continue to offer the Hyper-Threading technology we’ve evaluated today.

We have to hand it to Intel, we honestly expected Hyper-Threading to be a big flop initially on the desktop because of losses in performance. It seems as if Intel has worked out virtually all of the issues we ran into when we first looked at Hyper-Threading on the Xeon processors several months ago. With the 3.06GHz Pentium 4 you thankfully won’t even have to worry about whether you should enable Hyper-Threading or not, the technology does more good than harm.

Hyper-Threading in its current form is very much an infant technology, the potential for it is huge and it can grow into something much larger than what we see here today. It is impressive that we are able to see some serious performance gains in encoding and 3D rendering applications, as well as in isolated multitasking scenarios but the true benefit of Hyper-Threading comes much further down the road. With compiler optimizations and programmers developing with Hyper-Threading in mind, we’ll see much more dramatic performance increases in the future.

Today, Hyper-Threading still comes at a fairly high cost as you have to purchase Intel’s flagship Pentium 4 processor to get the technology. The beauty of it is that at < 5% die cost, Intel won’t hesitate to migrate the technology across their entire line of CPUs. What will be interesting to see is whether or not the value Celeron line of processors gets the technology as well.

The 3.06GHz Pentium 4 is the first step in a long road ahead for Intel as they embark on a quest to increase Thread Level Parallelism after extracting parallelism from instructions for the past decade…

It pleases me to see that Anand Lal Shimpi is a little more cautious with his comments than Frank Völkel , Bert Töpelt and Uwe Scheffel. (I wonder why Mr. Pabst didn’t want to look at the new toy).

Nevertheless all are quite correct to understand Intel has a new flagship against its battle with Advanced Micro Devices.

Unfortunately this is AGAIN a development that will force its users to buy specific operating systems that support its technology.

Windows 2000 does, and some mobo manufacturers, such as Asus, are even going to try to add support for hyperthreading with a BIOS update for the latest i845E boards.

Selling already. :bigsmile:

Quote from the last part of its conclusion:

Intel is once again changing the face of computing with their Pentium 4 Hyper-Threading, and just think about this for one moment. Imagine how much better the performance will get as software developers start programming with HT in mind. Intel’s Hyper-Threading is in its infancy and we are bound to see even greater things coming from it in the near future.
