BF4 Retail CPU scaling measured

What PSU do you have?? What temperature does your GPU have?? What temperature is your CPU?? What clockspeeds are your CPU actually running at?? Is it throttling??

How is your RAM arranged?? Is it a 4GB stick and a 2GB stick?? If so,the RAM is not running in dual channel.

The BF4 Beta also had an issue with load balancing with six thread CPUs,which is not present in the retail game. I would make sure all the latest patches are installed.

I am patiently awaiting the new road map to see if steamroller will ever come to AM3+.

So, in less than 2 weeks we should know if 4,6 and 8 core Steamrollers are coming to AM3+....if this info is accurate.

presumably, if they say nothing at this event, it will be safe to assume it wont happen...:confused:
 
If they do put it on AM3+, there will almost certainly be a new chipset, whether or not it requires it is the question.

It's just, if FM2 was sacked off (Which was newer than AM3+) I'm sceptical.
If SR does come on AM3+, then I'd expect an exodus from the FM2 crew.

Yeah, probably a good assumption.

Unfortunately for me a proper gaming/workstation upgrade from my current i7 920 X58 build on the Intel side is going to an X79 LGA2011 but the price of entry is huge. £300 or more for a really good motherboard and £460 for a i7 4930K is just crazy and this is what makes AMD look very tempting. If we find out Steamroller will be coming to AM3+ then I'd probably grab myself an Asus Crosshair V Formula-Z and take it from there.

Anyway, back to the game performance a lot of these results need confirmation from other testers over the next few days/weeks.
I'm getting a lot of mixed performance with my current setup, while the framerates don't seem too bad it does stutter and just doesn't feel as smooth and responsive as it should.
 
Would the performance difference be noticeable enough for it to be worth it?

It should be... I changed my brothers CPU from an old Phenom II X4 955 to an FX-6300 and he's very happy with the results. I then changed his GPU from a 1GB Radeon 6850 to a 2GB Radeon 7870 GHz edition and he's over the moon with the performance gains :). He's currently playing through Bioshock Infinite with everything maxed out (at 1080p) and it runs nice and smooth, but i'm not sure how taxing that game is anyway.

You can get a quality motherboard for £190-£235 (P9X79/P9X79PRO) and an excellent processor for £250 (i7 4820K). Obviously, when you're speccing a way overspecced motherboard and premium hex core chip that blows anything else available away it's going to be costly. :p

Yeah, that's kinda what I meant. To really upgrade from my current i7 from a VM workstation point of view (that is also my gaming PC) I should be thinking about a hex core chip which is stupidly expensive, and I wouldn't want to get a bottom end motherboard for a CPU like that so the costs just spiral out of control. (I had forgot about the P9X79 (was using a sabertooth as a baseline board) but don't know anything about it's power phases etc, anyhow that 's going off topic a bit).

I seriously doubt there will be a Steamroller based part on AM3+, the platform is getting old now and I can't see it making financial sense to design a new North Bridge to implement PCIe 3.0, etc.

But it would ne nice and easy (and cheap) for AMD to do an 8-core FM2+ part: put a pair of Kaveri dies on the same package (Core 2 Quad style), link them via HT and shut off the iGPUs to keep the power use down.

That would be a monster chip for gaming if SR's IPC improvements are as good a rumoured.
 
Someone please help me. That chart shows FX6300 running at great FPS. I have a GTX590, FX6300, and 6GB ram, and the game runs like garbage, often dropping to 15-20fps in intense situations. I've tried

1) Disabling Sli
2) Disabling 2 of the 6 cpu cores
3) Overclocking
4) Re-installing to a different hard drive

FX6300
GTX590
6Gb Ram
970 Extreme 3

And it's still the same, horrible cpu-bound performance. If I run at 1024x768 all low, still getting the same bad framerate.

Can't really play as its too frustrating.

It'll be one of a few things.

1. Your CPU is throttling because it's getting too hot. BF4 is a core eater.
2. Your VRMs are weak and are getting too hot. Asrock SUCK at making boards. They sell them with 4+1 VRMs then leave you to work out that it shouldn't really work.
3. Your GPU needs updated drivers. Nvidia may sort you out, or, do what they did to me with my GTX 295s on BF3 and not sort it out, forcing me to buy a more up to date GPU.

What cooler are you using on the 6300?
 
Ok I know I am an amateur but here are my initial results on BF4 (first mission). I was able to get a fairly reproducible run on campaign and hence why I chose to put up these FX8320 comparisons at different core clocks. Each run on campaign was run 5 times for 150s each and results are averaged over the runs.

I will attempt to do the same on multiplayer but initial results even on the same server and map don't produce comparable results unless I do hundreds of runs.

First up, min/max and averages at 4.6, 4.8 and 5 GHz on the 8320:



Next, overlay of 3 runs side by side. Bit of a mixed bag really, hence the need for quite a few runs to get a good sample:



In terms of GPU and CPU utilisation, I can't say I saw any core at 100% in any of the CPU clocks tested (was around 70-80% ish). I also didn't see max GPU utilisation in any CPU clock (max in GPU 1 was early 90s and 80-90% for the second GPU):

5 GHz:


4.8 GHz


The game runs very well on the system with no tearing and feels extremely smooth. Overall a nice experience. Not sure what to conclude in terms of bottlenecking but I think bumping the CPU clocks helps a little.

What program are you using to create those slides?

Nearly linear scaling with clock speed, clear sign of being CPU bound.
