THE BF4 BENCHMARKS THREAD

Sounds like they have a lot of optimization to do if it's running so poorly n SLI/XFire rigs.

Would hypertheading help ? I am not sure an 8 threaded, 4 core latest gen i7 at 4.5G would gain anything significant over a higher clocked 2500K ? And of course another 7950 for xfire.

If you do go xfire, yes an i7 will help a bit.

Does a thread on a i7 2600k for example = the same performance as a core?

My cpu is 4 cores 4 threads a AMD cpu can have 8 cores.

Sorry for OT question

So do we have enough evidence yet to see if LtMatt's predictions of 2GB VRAM not being enough to run more than 2xMSAA with playable framerates?

Playing at 1080P everything on High and 2 X MSAA on a 64 man conquest server

2013-10-01 23:40:55 - bf4
Frames: 8771 - Time: 181710ms - Avg: 48.269 - Min: 28 - Max: 88

same again on 32 man domination server
2013-10-01 23:40:55 - bf4
Frames: 8771 - Time: 181710ms - Avg: 48.269 - Min: 28 - Max: 88

VRAM Used: 1899MB

I want to play at constant 60fps at these settings. I think when it comes out retail it will be better optimised and I'll reach that. It was the same with the BF3 Beta. Or is my i5 750 showing its age (it's the first generation i5)

Depends on the nature of the workload - I'm seeing good utilisation on all 8 threads (4 core + 4 hyper thread) though - tbh it doesn't seem to be stressing this CPU at all.

On ultra preset I had 2.7gb 1080p

Thanks.
The good thing if Amd cpu's do start running games better it's not to much to change.

No, HT is way behind additional cores. It helps with software that expects more cores though for sure. If you look at the BF4 graphs for AMD CPU usage it maxes out the six cores of the 6300, and puts the 8350 under quite heavy load.

So do you think a AMD cpu will start showing it's worth with next gen so called games?

As a generalisation yes but it depends a lot on the nature of the workload and in BF4 it seems to utilise HT threads well.

Something interesting I just noticed is the way its threading resource fetching which might explain the stuttering some people are getting. (Open task manager and watch the graphs as you move about and go from standing still looking at the floor to moving about looking around). (EDIT: Basically it looks like the threads for handling loading data in and out are always dedicated to the last or the last 2 cores depending on CPU whereas all other worker threads are able to automatically be assigned as the OS see fits which sometimes seems to be conflicting if other threads are busy on the last 1-2 cores at the same time the engine needs to load/unload data).

Yes. All next gen console games need to use 8 relatively low powered cores, so will be coded similarly to BF4. Existing games that use more than 4 cores tend to do great on the 8320/50, but this is probably the first game to use them well.

It works well as the game will try to use 8 cores, and so takes advantage of HT. If the 4770K had 8 cores it'd be amazingly fast, but games using more than 4 cores have definite improvements with HT, especially it seems with minimum frame rates.

Edit:

Check out this thread for Metro 2033 benchmarks on the exact same PC, same OS/drivers, just with the 4670K and 4770K swapped (first image and near to last):

lol all this bad framerate and stutter talk makes me kinda glad i cant play the beta.
Although since i gave away one of my 5870 cards i think my single 5870 would be a slideslow by the sound of this

Remember though guys mantle should improve fps a lot on this should it not....and it will be better optimized by retail.

setter · 2 Oct 2013 at 00:11

Tried a brief blast earlier with ht off, was very stuttery and cpu use was quite high. Gpu use didnt go over 80%. Pretty much the same as when i had a 3570k.

And did it NEED all 2.7GB or did it just use it because it could?

Like how people that drive a Porsche 911 (or similarly fancy car) will use 2 car parking spaces even though they only need one, because they found 2 next to each other and thought "**** it I'm special cuz I've got a nice car so I'll use 2 spaces and those common people with cheap cars will have to find somewhere else to park that not near me".

lol I get better results holding the clocks back to 1.2GHz (and not a huge drop in performance from normal clocks with HT on) with HT on than letting it run full whack with HT off at almost 4x the clock speed. (its a stuttery mess with HT off). Only casual observation but looks like its been optimised for 8 low performance threads for the sake of it........

EDIT: Obviously its a beta and I'm using beta drivers and all that.

Any need for post like that? I have no idea if it needed it or not just posting what hwinfo64 reported.

Some people.

After reading that back, I think you have issues. Go see a doctor.

This is my reasoning behind deciding that my next CPU is an AMD FX8. I'm currently on a a Q9450 which I have had for many years. At the time I bought it (used) most people said quad core wasn't needed. Now people wouldn't consider a dual core for gaming. I need to upgrade and can't afford an i7 so will be getting an octacore AMD in preference to an i5. Maybe I'll be wrong but I also need more threads for other tasks too.

I'm no expert but I think HT on Intel uses spare unused CPU cycles for hyperthreading. As the CPU gets busier HT may become less efficient. However i7 is such a great chip that it has enough brute force anyway.

Look at the Metro 2033 results I mentioned

Absolutely appalling stutter on an i5 clocked at 4.5GHz, but fine on an i7 at stock. It seems that when a game expects more than 4 cores and is CPU heavy, it causes some thread bottlenecks on the CPU that result in stutter. The average FPS is probably not all that different.
