Why disable hyperthreading i7




















This can slightly boost overall performance for the entire system. Another small but helpful performance factor is keeping your Intel Chipset Drivers up to date. So this does help too. Make sure it is set to Max Performance. However if u sometimes like to run off battery, u might want to switch the power profiles back to Balanced or Power Saver, as a means to help lengthen your available battery runtime. But on AC Power, especially for gaming purposes, it really helps to have everything setup for Max Performance.

SSDs are more affordable now and u don't need a large one. Even with games installed to a secondary HDD, everything will still have faster load times and the OS will be very snappy and responsive. Then get an external USB 3. For things like Games, install those to the HDD. Many wrong statements. Look at BF4, the game everyone thinks needs a hexacore to run, yet it sees no FPS drop when 4 cores are disabled If you are going by your logic that the devs are going to optimise games for 8 cores, why are you getting a quad core and not a x?

Cores are not threads, threads effective simulate more cores or give you "fake" cores. Watch Dogs specs are exaggerated, there's no way an I7 is required. It's like food go-off dates; they're always way under the actual time the food goes off, because they want to make sure no one sues the company for eating rotten food.

Core clock speeds really matter- you can gain 10 FPS sometimes from 3. And that could indeed make a difference if you're getting a choppy So yeah And then you're going to disable HT essentially making it an I5? Every time you want to play one of these demanding games or whatever you're going to have to go back into the BIOS and enable it The graphics card is the most important part of a gaming PC, s of people forget that.

Basically a system bottleneck can occur when a component of your PC is limited due to another This is what Intel did correctly and AMD failed at Multiple core applications and graphical calculations run great.

However, Intel went another direction, they saw that the CPU was already at max peak and therefore redesigned the motherboard for 2nd, 3rd and 4th Gen Intel PCs.

This did mean you had to get a new motherboard with the CPU, but they now work more together. They reduced the bottlenecks of the motherboard which in turn slowed down the CPU no matter how overclocked and powerful it was. You also don't need the extremely overclocked memory for example as the motherboard takes care of the rest, etc. So when building a PC, look for a even flow of components which work well with each other. You end up with a fast and more stable platform. It might not even hit the benchmark results like an overclocked system, but in a side-by-side compare you won't notice, except underneath it will be producing less heat, be more stable and have a longer lifespan.

For a i7 CPU Haswell.. This will give you a better layout, higher quality components and future upgrade possiblilities. For DDR3, I would suggest sticking with 1. You might notice I'm purchasing some overclocking components, as they are normally much higher quality if you can get for a good price , but simply not overclocking them if I don't have to.

Then depending on what resolution you desired p or higher? Basically all I'm saying is keep it balanced, you might not have the budget for all of that, but keep it in mind for future upgrades or simply going a bit lighter on one area of purchasing to even out another and making sure they are using their full potental. Bad-Motha , please respond to my reply! I wanted first an i5 , but then I changed my mind to an i7 Then I looked at CPU comparison - i5 vs i7 - and in single-threaded applications and games , the i7 has negative performance also, less FPS on some games.

And I searched if hyperthreading can be disabled. IT CAN from the bios; it's simple. Viimeisin muokkaaja on Myth[Alex] ; 7. Yes, it's entirely possible and some people do this due to considering some games have better performance with it disabled. However, honestly you won't see that much difference now and it's best to keep it enabled for the OS backend work. Even the old WinXP is aware of hyperthreading and would put it to some good use with multi-tasking.

Only a very few older games have shown higher performance when HT is off, usually however when HT is off you also get a drop in temperatures by a few degress, which is ideal for overclockers, however useless compared to a drop of 10 degrees by just replacing the standard CPU grease with Arctic Silver 5, etc. These days there is little or no reason to disable it. Unless you are having overclock or heat issues, leave it on, much more applications and the OS will benefit from it vs a few games losing out on just a very tiny performance increase.

Overclocking next gen PCs 3rd Gen Ivy Bridge or better is a waste of cash and time, it's just for power users who want to show off or have fun with it. If you wish to overclock use a Sandy Bridge which can handle higher temperatures and therefore overclock more than an Ivy.

Belong that CPUs have been greatly reduced in size, compressed with smaller technology, lower voltage, and therefore you see less in overclocking performance. You are actually more just increasing heat and shortening lifespan, compared to getting a few noticable FPS.

However, it's not even required. The overclocking won't show any noticable performance gain, only higher benchmark results. The motherboard will take care of the rest, with direct access inbetween CPU and memory processing as well as CPU and graphics processing.

Getting extremely overclocked memory such as MHz, normally also results in higher CL12 timing, meaning your actually slowing the system down. Rather than overclock, it's best to check and reduce all system bottlenecks instead, resulting in an all around noticable performance increase and stability. It should behave like an i5, but it will be a tad faster, due to the high cache and also higher stock clock speeds.

But why disable hyper-threading? For gaming purposes You not gonna need HT for games really. However if u want to go beyond the rated Turbo speed, I suggest ditching the stock Intel cooler and install a 3rd party one. This can slightly boost overall performance for the entire system.
