What do you mean where I take them??? OH you mean as where in the game? Yeh I am trying to choose as wisely as possible... it is difficult to decide though. In ASSASSIANS CREED I am going to get to point where I am in a town with lots of people... With the HITMAN Absolutions there is around 1000 NPCs being controlled by the PC it is far more demanding and CPU linked than anywhere else in the game. I was very happy to see that it scaled so well...

It would be a dream for me to be able to prove that multiple games could benefit from more than 4 cores and even better benefit from HT...

All I have to work with is old data that shows HT doesn't do much at all (within margin of error) and most tests for multiple cores are showing little to no benefit from more than 2 cores...

I really wish there was new testing out there... but there isn't so I guess I will have to do it myself and hopefully with others help

If any games scale to 4 cores with HT vs 4 cores without HT then I'm buying an i7 LOL...

I can't afford 2011 or 2011/3 platform... so an i7 will have to suffice... IF it can actually show a difference in performance!

What is it that you meant when you said "Are you beginning to see what I'm saying now, givemedew?"

Because if it is what I think it was that you meant then your making a fool of yourself... What I am trying to show is exactly what that guy was talking about... Reputable or not a big name in reviews and opinions said that in BF3 there was no difference between 2 core no HT and 6 core HT.

Intel is releasing a dual core cpu that is unlocked...

So you will soon have your choice between 2, 4, 6, 8 cores some with and some without HT options...

WHEN DOES IT STOP BEING AN INCREASE IN PERFORMANCE??? Because there are a lot of people saying that 4 cores of Intel Haswell like an i5 is better than 8 cores of AMD? Obviously someone says 2 cores is enough in games like BF3 and I bought that hook line and sinker...

Somehow you seem to think that there is no way that any of the tests I am going to do can shed any useful light on what CPUs people should actually get...

I say your wrong and you where just looking to say something negative about everything... and that is often your stance on things.

I also say that all the data that I am going to show will be HIGHLY RELATIVE to the purchase of new CPUs for people...

I have already shown that you can't even play BF4 with the upcoming unlocked Pentium... I have shown that Hitman: Absolutions is highly scalable...

I don't need you to reply because all you have done is waste space on this thread by trying to pick what I am trying to do apart and you didn't actually contribute a single good idea... I was asking for HELP not some guy to come in and say this test is pointless and the data will be garbage...

If you have a further reply try to keep it too something that is helpful to the people who will be interested in these tests... It is going to be a lot of work for me to do this and I am not doing it for my health or to get paid and I will be trying my absolute hardest to prove my hypothesis wrong in every way which is why on the one game that hasn't scaled from extra cores I am going to try to do other things to show scaling.

well thank you for the end of your energy as all you where doing was trying to poke holes in a perfectly sound test that will provide useful information to people instead of trying to assist by improving the test... if that's all I needed to do I wish I would have done it sooner.

Starcraft 2 would also be nice to test since it's very CPU dependent unlike all the other games in you list.

As a prediction, i don't think a single game will get more than 50% higher fps than the fps you get on 2 cores.

Edit: Saw hitman bench, already beats my prediction smile.gif.

Since I had it installed, i just took some benches from Far Cry 3 which might be interesting to compare with yours later. Note that they're very unscientific, just some rough-and-ready manual runs. The CPU is a stock 4770k and the GPU is a 780 Ti, and I lowered the resolution to take the latter out of the equation (as you can see in the GPU load usage graphs). As I said, the runs were manual, but I kept to a very tight route. Each benchmark was only 60 seconds, frames taken by FRAPS.

The main problem with these benchmarks is that I just did them in a random area, not one of my 'known CPU bottleneck' areas (ie. the places where I see it drop below my 60fps when I'm playing normally). As you can see, there is still plenty of difference to be seen, but core scaling might be even more pronounced in the 'known CPU bottleneck' areas, which usually involve a lot of NPCs. Just imagine if the game did it's AI processing on the third thread, for example? Going from 3 to 2 cores could be crippling in a high NPC count/town area, even if you didn't see it so much just driving around the jungle...

4 Cores Enabled:

farcry3_d3d11
Frames: 5840 - Time: 60000ms - Avg: 97.333 - Min: 77 - Max: 129

farcry3_d3d11
Frames: 5780 - Time: 60000ms - Avg: 96.333 - Min: 78 - Max: 128

(Ran it again to check for any potential catastrophic variation, pretty good for a manual run)

3 Cores Enabled:

farcry3_d3d11
Frames: 4455 - Time: 60000ms - Avg: 74.250 - Min: 61 - Max: 91

2 Cores Enabled:

farcry3_d3d11
Frames: 3364 - Time: 60000ms - Avg: 56.067 - Min: 45 - Max: 74

1 Core Enabled:

[Far Cry 3 fails to launch]

Bonus Round:

4 Cores Enabled + Hyperthreading:

farcry3_d3d11
Frames: 5227 - Time: 60000ms - Avg: 87.117 - Min: 66 - Max: 127

The HT result is perfectly in line with the negative scaling I've seen since my first HT CPU (2600K). It's why you used to see the 2500K score higher than the 2600K in some reviews. This is exactly why I always disable HT.



(these graphs are just for casual interest. Ignore the spikes [menus], tails and numbers [obviously from when I exited the game], just compare the stable parts of the graphs. Also bear in mind that the way task manager reports CPU usage is possibly unreliable).

Games don't determine CPU cores used... the engine does. Example, I forget what Skyrim runs on, but it only allows for two threads. You shouldn't need to do a test on the games, I wonder how easy it would be to find out the thread limits on the engines.

Oh really? God an engine mod? Or are you looking at the task manager and seeing the green lines increase over all cores? Task manager lies. On an 8 core system (like me) my CPU peaks at 25% for Skyrim. 25% of 8 = 2. I don't know how many times I've had to point this out.
