[Benchmark Results] Single & XFire 7870's - October 2013

post #1 of 5
Thread Starter 
So I am making this thread for people who are on a lower end budget and want to crossfire for the best performance.


Note: These benchmarks are taken with the Final 13.9 Driver Release not the 13.10+ BETA's

Cards Used In Benching:

Card #1 Running at x16 in PCI-E 2.0: MSI 7870 OC Edition @ 1100/1200 (<-- includes additional OC Added to match Gigabyte)

Card #2 Running at x4 in PCI-E 2.0: Gigabyte 7870 Windforce OC Edition @ 1100/1200

Motherboard: GA-970a-UD3 Note: I am using the Rev. 1.0/1.1

Processor: AMD FX-8320 @ 4.2Ghz (lowered for stable benching)

Now to get to the benchmarking. I am running all tests at 1080P - 1920x1080

I used 3dMark not 3dMark11 just 3dMark: http://www.3dmark.com/

Test #1 (13.9 Final Release Drivers): I am only using the MSI card in the first slot for the single card performance running at x16 and its default clocks 1050/1200. Here is the link of this test for all the details: Single 7870





Test #2 (13.9 Final Release Drivers): Running the MSI at x16 in the first slot and the Gigabyte at x4 in the second slot. These cards are crossfired with the same OC 1100/1200 Note: 13.9 Does NOT include frame pacing. Here is the link of this test for all the details: Dual 7870's










Note: the performance on test 2 is scaling better because of the extra overclock.

The crossfired 7870's scale exactly in-line with the GTX 780 and that is in x16/x4 Configuration a x8/x8-x16/x16 should have 5-8% better performance.

I will update these benchmarks when a more stable release of 13.x drivers release THAT INCLUDES FRAME PACING where I can actually install the display driver without failing. I hope this helps some of you trying to decide whether or not to upgrade!

Also if you are curious, I get anywhere from 90-150 FPS (Updated Depends on Map and C-A.I.) maxed out settings in BF3 on the 13.9 Drivers in Crossfire with this setup.

Price: This crossfire setup cost me exactly $400. BUT!! you should be able to pick up two used 7870's on ebay for around $300. That is $300 Less then a GTX 780!

Let me know how to improve etc thanks!

That's pretty impressive. So with 2560 stream processors you're matching 780? Makes me wonder what 290x will do with 2816 SP's

Thanks for this, gives me a general idea on how a second 7850 would perform biggrin.gif.

Remember you can crossfire a 7850 with a 7870! smile.gif
