D300 crossfire benchmarks?

[branana]

Are there published benchmarks for these D300s crossfire benchmarks in Windows out there? I'm wonder if 2x D300s perform similarly or better than higher end single cards in games such as Battlefield 4.

I didn't see any benchmarks on Windows yet.

But BF4 seems to be very buggy to unplayable when it comes to dual GPU support. Lots of people seem to disable the their second GPU in order to play.

I am playing BF4 on a 21.5 inch iMac (late 2013) with a 750M. It runs quite well almost everything set to high on the native res of the iMac.

Should be around 7970m in crossfire.
Same chips, same clock speeds, same memory bandwith and mount of memory.

Heard there's an update coming with better support for AMD hardware.

So around 180-200% of a 7970M's framerate eh?

If D300 is like 7970m, then D300 is pretty good according to Tom's Hardware Hierarchy Chart. It's 3 steps below the 7970 Ghz Ed. I read somewhere on here that the 7970 is like the D700. I wonder if the 7970 = 7970 Ghz Ed, same card?

According to the chart 7970 = 2x 4870, thus 2 D300s would like 4 4870s. I have the 4870 right now in my 4,1

D300 = 7970M hardware wise. Clock speed is the same, same type of core. Amount of memory and bus size is the same. Memory clocks are actually slightly better on D300s. So they should deliver around the same performance unless the driver messes things up.
