AMD FX 8320 analysis

is that under water? i will using a h100i but may move to custom water after

H100. Don't bother with custom water unless you want to chase Cinebench records for the chip. Some of the games actually showed drops at 5ghz. 4.6-4.8 seems to be optimal, so just get it there with as few MVs as you can and leave it be. H100i is more than enough IMO.

ALXAndy, how easy was it to get the CPU to 5ghz with the ROG board?

im really really considering this setup from my i5 760, also im running a 7990, is there any bottlenecks anywhere?

i dont suppose you have company of heroes 2 that you could do a bench on with the 5ghz FX and 7990?

COH2 tends to be bound a bit by single threaded performance, but if you OC it's fine:

thats awesome, thanks guys

may i ask why drops have been shown with 5ghz over 4.6-4.8?

im also wondering how much mantle will help this chip and radeon cards out when its released :D

If it's dropping at 5GHz over a lower clock it must be throttling. I'd aim for 4.8GHz though myself, anything higher is a bonus but obviously means more heat. A high end air cooler will do 4.8-5GHz on a good chip as well.

It's not throttling. I have them all disabled. I know when it's had enough because it'll literally shut itself down lmao.

I did start benching at 5.2ghz but it proved too much.. I think the FPS drop because it's either only using a core or two. Either that? or the game engine itself may not like being pushed so hard.

But yeah, on the CHVFZ I've disabled all of the safety settings and it's seat of the pants :D

Mantle is basically there to rule out the CPU completely and leave everything down to the GPU. Hence AMD's recent statement that you could down clock the FX 8320 to 2ghz and it wouldn't matter.

The CPU will throttle if it decides to, there's no way to turn it off as it's part of the hardware design. It's the only reason you'd get lower FPS with increased clock.
 
Hmm. Well tbh I know for a fact it's not throttle. What it could be is simple margin of error.

You'll note there that I hit 800 points in Cinebench. Was a sheer fluke. I've been capped at around 795 for ages, yet all of a sudden I finally hit 800. What I should have done was run every bench three times and take the average score. Sadly that would have taken so much longer.

Maybe next time I won't go so in depth lol. It's got to have taken me a week all told.

Mantle will help if its supported. It has huge potential specifically for such cheap 8 core chips. bf4 in December could prove interesting.

Tepic: Damn, an i7 is gpu bottlenecked at only 2.5Ghz in company of heroes!

From what I've been hearing Mantle will pretty much attempt to eliminate the CPU completely from the equation, leaving everything down to the GPU.

BF4? all noises point to it only being used for the lighting or shading. Shame really, but I guess the initial engine work is a lot of work.

It won't be just for the lighting and shading, AMD and DICE have said they have reduced draw calls and other CPU tasks....... The lighting and shading in BF4 is already done on the GPU so they can't offload it from the CPU if it's not done there to begin with.

Good to hear ! I must admit I did feel a little disappointed when I read that.
 
Just to allow some synthetic bench comparisons with Andy's results. Here is a summary of mine with the following system specs:

Win 7 Ultimate 64 (I think Andy uses Win 8)
FX 8320 @ 5GHz
7990 at 1100 MHz core, 1575 MHz Mem
Motherboard is a CHVFZ


Away for a couple of days so will post my BF4 results on Sunday most likely.
