In this case, enabling hyper-threading creates four threads, allowing each core to perform two tasks at the same time. This process improves the efficiency and boosts the performance of your CPU. You can then run more than a few demanding programs at the same time without experiencing any lag. But most video games that are now being released usually do well on hyper-threaded CPUs. It helps only if the tasks you perform require it, in which case there can be as much as a 30 percent increase in speed and performance.
Also, if you have to make a choice between two CPUs where one has more physical cores while the other has fewer but with hyper-threading enabled, it is better to go for the former. For instance, if you have an opportunity to use a quad-core four cores CPU without hyper-threading enabled, it is preferable to choose it over a dual-core two cores hyper-threaded CPU.
However, if the HT-enabled CPU also has four cores, then the choice will now depend on the kind of apps you run on your computer. You can look up how to do so for your device. Keep in mind that not all processors allow hyper-threading. If they both have the same value, it means that your CPU cores are not hyper-threaded. I have verified they are 2.
These were identical machines purchased in bulk, and some have HT enabled, some don't. They do show a non-acpi hal. As these are production machines even a repair install with the subsequent software chasing would not be ideal, so right now we are testing a machine that DID get HT enabled. It may not even make a difference. The biggest problem is an excel spreadsheet that is cpu-limited. Even a Core 2 Duo won't open it in less than 10 minutes.
We're trying to get it down from 17 with the P4 2. I have an HP here at work with the same issue. A user was ADAMANT about migrating his laptop to a desktop and preserving every single setting and program to as close as possible as before.
The desktop is a Core2duo but only one processor shows in taskmgr. I haven't wanted to mess with a repair install or changing to ACPI This guy is also a workaholic and finding a window to work on this desktop is extremely difficult. You could try manually replacing the HAL by extracting halaacpi. If halaacpi. After extraction, rename to hal. After that, HT should work.
I did this a few weeks back to a PC in work, I used the devcon utility as described in the link below. Even then MPS has to be version 1. ACPI is the no-brainer solution. Chris A Golden Member. Oct 11, 1, 1 That is a good question that I unfortunaly do not have the answer to. I have been watching this thread hoping to find out.
Tetsuo Lifer. Oct 20, 10, 0 Your mobo has to support it, just go into your bios, and there should be an option "enable hyperthreading" or something along those line. Ok here it is. Look Elsewhere Intel is preparing to start providing hyperthreading in its mainstream processors, not just its server-oriented products. At a very simplistic level, hyperthreading treats one processor as two, harnessing unused clock cycles to process two separate streams of instructions.
The performance gain can be anywhere from 15 to 30 percent, depending on the workload and instruction mix. It requires an operating system and application software that support multiple processors. As you've no doubt guessed by now, Win XP Home doesn't support multiple processors. Win XP Pro does, and so does Windows Microsoft has no plans to add multiprocessor support to Home, having figured that home users would never need this feature, even though Intel had warned that it was coming?
Intel, meanwhile, is trying to cement and extend its performance lead by combining ever-faster CPUs with hyperthreading to handle multimedia processing and other high-end consumer tasks.
Do you pay more for your gasoline when you drive a minivan instead of a sedan? Why should you pay more for your operating system just because you choose a hardware platform with higher capacity? We can only hope the Microsoft folks will see the absurdity in the arbitrary differences between Win XP Home and Pro and make Pro the sole standard, at a price that keeps systems affordable.
Or maybe they just like to cause as many problems as they solve. Dec 2, 10, 0 0. Thanks oldfart you cleared up a few things for me. Canterwood Golden Member. May 25, 1, 0 0. OK, let me clear something up here. Its all about physical and logical processors in hyperthreading. XP Home supports 1 physical cpu ie 1x p4 3ghz.
XP Pro support 2 physical cpu's ie 2x p4 3ghz However when hyperthreading is enabled, the the operating system sees two cpu's. Although XP Home only supports one physical cpu, it can make use of hyperthreading as it can differentiate between physical and logical cpu's so will see two cpu's. XP Pro can use two physical cpu's with hyperthreading ie it sees a total of 4 cpu's.
Windows CAN make use of hyperthreading, but cant tell the difference between physical and logical cpu's. Sees a hyperthreading cpu as two physical cpu's. As Tetsuo says, you need a motherboard that supports hyperthreading and you enable it in the bios. Hope this helps. May 6, 0 0. How do I quickly find out if my system has HyperThreading enabled?
