Hyperthreading - Finally an answer

Now THAT was new to me.

I may be stating the obvious here but everyone knows that IL-2 uses hyperthreading too? It does. Although the improvements are limited to my understanding. It was talked about mostly during the Forgotten Battles release and then forgotten. I was assuming that IL-2 Cliffs of Dover would make use of it in some way as well.

If I were buying today... the Core i5 2500 is a great buy but the Core i7 2600 is just worth the extra money. Both are incredible bangs for the buck in higher end systems.

This is not good news...

Wait infact its not right - they cannot enable or disable hyperthreading. Multithreading hey program, hyperthreading is done automatically by the hardware and the game has no control over it because it sees virtual cores.
Answer: Hyperthreading is enabled, because the cpu dictates that. Multithreading on the otherhand... Seems like a very bad omen.

I think Oleg was genuinely answering whether a hyper-threading processor (eg i7-2600K) would give any advantage over a non hyper-threading (eg i5-2500K) [so to answer Feuerfalke - not all multi-core CPUs use hyper-threading]

His answer maybe reflects the results of some testing done by Custom PC mag when the Sandy Bridges came out:

in Crysis on their test system (DX10, 64-bit, 1680x1050, no AA)

i7-2600K
min fps = 36

average fps = 64

i5-2500K
min fps = 34

average fps = 60

There you have it - Crysis takes advantage of hyperthreading too, 'but not so much'

(As others have remarked there is much confusion on the go over hyper-threading V multi-threading.)



...and just to confuse things further, when the 2 processors were overclocked the i5-2500K had higher min fps (42 V 37), and equal average fps to the i7-2600K (both 67). Apparently, hyper-threading doesn't respond so well to overclocking. Underlines the fact that things are more complicated than they may at first appear.

I went for the i5-2500K, but hey, it's your money

To be really safe wait another week and then check up on the feedback

Yea well it would have to use more than 4 threads to be "hyperthreaded", for intel cpus. Crysis is getting a bit dated now as most people were on single or early duos when it was released. On the positive side if the game uses 4 threads and you buy a i7 with hyperthreading, you can run the OS and other software on the spare threads on the cores with the least cpu load.

Depends on how rich you are, really. Are 2-3 fps worth a 100 quid to you? Buy a 2600.

That's the bottom line for me as well. Whatever the hardware component in question, if i pay an extra 1/3rd of the price i expect an extra 1/3rd of performance too, but since that never happens i just buy the second best component and save enough money to possibly upgrade another one.

This is a better strategy overall and gives better all around performance, assuming you are a mere mortal like the majority of us and don't have an endless supply of money. If you really are super rich case go ahead and buy the best you can find across the board, but for the majority of people it doesn't work out that way
For example, one could buy the top of the line CPU, or the second best CPU and an extra 3-4GB of DDR3 RAM for the same price (depending on whether he runs a dual or tripple channel mobo) or an SSD, etc.

Your sarcasm aside, my comment was regarding the post made on fact that single-core processors are probably not available (and if they still are, who would want to buy one? especially for gaming?!.)

That being said, if you buy a new system, it's highly likely that it will be multi-core and IF it is INTEL (this added just for you), the question of "does COD support multi-threading" can be seen as "pointless" as it WILL or WILL NOT use it and there isn't a thing you could do about it.

Unless, of course, you use this argument to say to yourself "then I'll save money and buy a single-core based system" in which case, it's a logical fail.

So relax mighty Feuerfalke, no one's looking to take your cake.

It will use it, COD doesnt decide that. If the game uses over 4 threads then on i7s it will automatically switch to hyperthreading and if it only uses 4 the cpu will use HT anyway to run other apps. I5s are not HT btw.
