New 7850 + overclock results

[twelve25]

Well I just got a new XFX Ghost 7850 today (upgrade from 5770) and I am stoked with benchmark results, but maybe I was expecting more in games.

5770 with 100mhz overclock:
3Dmark Vantage GPU: 10359
BF3: 1440x900, High settings = 45-60fps


Stock 7850
3Dmark : 20226
BF3: 1680x1050, High settings = 50-70fps


7850 overclock (1050 GPU/1325 Mem)
3Dmark : 23118
BF3: 1680x1050, Ultra, MSAA 2x = 45-60fps, with 4x MSAA = 35-40.


So that's an impressive upgrade, but now I am worried about getting a bigger monitor.

What's your CPU?

BF3 is a pretty CPU dependent game.

 

[twelve25]

i5-2310 @ 3.5 Ghz

BF3 needs a good quad core cpu & very good GPU to perform well

The question becomes: more speed or more cores?

 

[twelve25]

my 2310 is running at 3.5, so I get benchmarks like a stock i5-2500, but yes, I do get occasional spikes approaching 100% on a couple cores at times.

Looks like I can run all Ultra with no MSAA or High with 4x MSAA. Which would you think would look better? Ultra with 2x is acceptable, but I get occasional drops in the high 30s when there is lots of certain kinds of effects.

No MSAA with FXAA all the way up.

You can try FXAA Injector.

Thanks.

I think I found my bottleneck. 1GB VRAM. I bought the bargain basement model ($141 on sale) and BF3 is using 985GB.

According to this, Battlefield can want more than 1GB on Ultra: http://www.gamepur.com/news/5768-dice-battlefield-3-utilizes-more-igb-vram.html


That said, I don't regret saving $50 to lose a few fps. I just played a few matches at 1680x1050 with everything on the highest setting except MSAA at 2x and it played perfectly. So this thing is a beast for $140.


Also, the one site that benchmarked this exact card was getting better results than me, but I just looked closer and they had used a i7-3960X, so that's just a tiny bit different....

I'm at least getting their stock results by overclocking my card, so it's not all bad.

At 1080P....not really at 1680X1050.
