***THE BF4 BENCHMARKS THREAD***

[dmferrett]

Just gaming: I agree a moderately clocked i7 is more than fine.

But while streaming to Twitch 40% of my CPU is being used before I even load into BF4. Then I can peak at 100% usage even with a heavily overclocked i7 so become CPU limited.

Which ain't good for my FPS .

So you do live streams to twitch or recorded streams or both? So who's looking at the twitch feed?

If you get another 780 you will max out your cpu if you try to stream BF4 to twitch. Infact you gonna hope mantle off loads the cpu enough to allow that degree of multitasking.

Live stream.

If I got another 780 then while streaming I would become CPU limited more quickly. Probably wouldn't get that much benefit overall while streaming.

I would need an overclocked SB-E/IB-E to really be able to stream without the bottleneck,.

Mantle would help but in my opinion, it will be limited to AMD cards only initially. While they iron out bugs and the like. By the time it's released and made open (if they do indeed go through with this) then I still can't see nVidia actually adopting it so I likely wouldn't see any benefits.

I'll weigh up the pros and cons as I normally do once it comes to upgrade time again .

Rusty i thought you bought a second hand 780 ?

Had to pull out as got a tonne of work coming up in next 4 months. Won't have anywhere near enough time to get as much use out of it as I would want .

Furry muff.

Guess you won't be beating my scores after all.

Give me a few weeks and ill see what i can do. Can only afford one 780 initially.

As long as you only have one ill take you to the cleaners setts.

One to start with, might use the funds from selling my 670's to buy another. Finding another wf at a good price might be hard though.

Hey there, don't mind me, but I thought I might drop some actual BF4 benchmarks up in this bizzatch

1080p.
Shanghai 64 All Ultra/4xMSAA with FXAA disabled for all three tests and all cards set to 1000/1500 with a 2600K @4.7Ghz.

7990

Frames, Time (ms), Min, Max, Avg
69256, 707828, 57, 174, 97.843

Power usage at the wall: 480W. Not sure if it peaked any higher.

Temps/GPU usage:

Spoiler

7990+7970 Trifire

Frames, Time (ms), Min, Max, Avg
57386, 582875, 57, 196, 98.453

Power usage at the wall: 532W average with occasional peaks up of 640W

Temps/GPU usage:

Spoiler

7990+7970 Trifire @200% Resolution Scale

Frames, Time (ms), Min, Max, Avg
38645, 653969, 0, 93, 59.093

Power usage: 650-680W

Temps/GPU usage:

Spoiler

Vehicles exploding and spectacular deaths were responsible for those low digit/zero minimums @200%.
It may look slightly more crisp than 100%, but I don't think it's worth the performance penalty.

So all in all... You're gonna need a high res screen to really take advantage of TriFire and probably a rather juicy cpu OC too.
I know, shocking news, right?

Is the i7 a big improvement Petey?

 

[Uncle Petey]

I believe so. Overclocking it from 4.4 to 4.7 (with plenty of room for more) has made a noticeable difference too.

Had a little go of the opening level on Crysis 3, (with the CPU @4.4 still) and gpu usage was at around 95% on each core and running happily at Very High/4xMSAA between 51-80+fps on the stock 7990.
That was a big difference compared to the i5.

I'd recommend the upgrade, though maybe not so much if your main (or only) game is BF4 considering Mantle is around the corner.

 

[LtMatt]

I just tried BF4 on my 2700K @4ghz and ran into some light bottlenecking with my 7990 @stock. Nothing major but not getting 97-99% constant gpu usage and this is at 1440P highest settings.

 

[Uncle Petey]

Can anyone tell me what the hell is going on with the 7990's gpu usage in the trifire 100% vs 200% graphs?

What was the vram usage, could've been something to do with that.

Either way you'll never get great results trying to tri-fire at peasant res i doubt. One 7990 is overkill at 1080p let alone another 7970 on top. Even with my 2700k@5ghz i get bottlenecking at 1080p with my 7990 at stock. Trying running the same test once mantle hits rude boi.

 

[humbug]

Ever had that What The..... feeling?

Hit Detection bugs.

 

[Gregster]

I am assuming that res is 1440P Petey?

Yeah thats pretty bad isn't it. Worst case scenario, but nonetheless shocking. Luckily ive never experienced it that badly.

Yeah, trifire is utterly wasted at 1080 and are you telling me that 9Gb isn't enough??!!! (ok, it's 3gb, but whatever )

ED: No trifire with mantle for me dude. Gonna be all plumbed in well before that

C'mon old man, I put it in bold letters for the pensioners

1080P Doh!!!

Very low frames mate or am I missing something?
