2 x XFX R9 290 VS 7990

[boot103]

Hey,

I happen to have two XFX R9 290's and a 7990.

I want to sell either the 7990 or R9 290's but want to keep the best performance.

I will run some benchmarks on both setup's and post them here.

I'm guessing the R9 290's will come out on top.

I wonder how the 2nd gen CPU running PCie 2.0 will affect performance ?

Also running two cards reduces the PCie Speed to 8x

PC Specs:

PSU: SilverStone Strider Plus 1000W (model SST-ST100-P)
Mobo: Asus SABERTOOTH Z77
Proc: Intel Core i7-2600K Processor
Socket - LGA1155
Mem: 16Gb
OS: 64-bit Windows 7
HDD: 120 GB OCZ-AGILITY3

PCIE Details

2 x PCi Express 3.0*/2.0 x16 slots (single at x16, dual at x8/x8)

*PCIe 3.0 Speed is supported by intel 3rd gen procs

R9 290's


Asus 7990

Nice one, looking forward to it.

Those reference cards need a clean though.

 

[JamesM]

290 will win

6 months in a mine, what do you expect.

Oh that typo.

They were mining in my dusty garage for 6 months

Had 6 R9 290's and 3 7990's

It paid for the hardware





Back to benchmarking !

7990 BF4 not looking good on 14.6 - Crashing all the time.

Have you tried the 290s on 14.6 yet, my cards run very well on those drivers.

Not yet. Will stick them in after the 7990 test's are complete. Will try Drivers 13.12, 14.4 and 14.6

We will see what FPS increase we get.

Definitely use 14.6, the fastest drivers yet.

Lets see if using Mantle fixes it. Looks like a DX issue.

Fraps doesn't support so to get the FPS using mantle I need to use the DICE benchmark tool

PerfOverlay.FrameFileLogEnable 1

im using 14.4 drivers with my 7990, had no problems with any game, but i cant monitor my FPS in BF4 with mantle

im not sure its worth the extra for me to get two R9 290's over my current 7990, price vs performance is not large enough for me to justify it

You can. Place this config in your main BF4 folder.

Yeah run as normal. Open it with notepad if you want to tweak the settings. You can alter the frame pacing method, (2 is stock and default, has a larger fps hit. I use method 1. 0 disables it) performance overlay, renderer overlay and the fps counter.

1= Enable
0= Disable
