System Specs

IGP 3200HD and radeon 3450 Crossfire!

Yeah i realised a spare video card here and my onboard were crossfire compatible, so i decided to do some testing.

3dm06 isnt too popular these days, but i decided to use it since the CPU wont be changing, and vantage would be too rough on the PC.

Test setup:
Windows 7 x64, build 7000
4GB DDR2 800MHz
Athlon 64 x2 4000+ (2.1GHz)
Gigabyte mobo who's name eludes me right now (will edit in later)

Asus radeon 3450 'super' 512MB
Onboard radeon 3200 set to 128MB

radeon 3200 IGP:
SM2.0 : 436
SM3.0 : 525
CPU : 1405
total : 1333

asus 3450 512MB
SM2.0 : 536
SM3.0 : 602
CPU : 1483
total : 1568

Crossfire!
SM2.0 : 692 (~30% faster)
SM3.0 : 830 (~37% faster)
CPU : 1510 (faster, but within the range of random change)
total : 2056 (~31% faster)


This post will be updated after i reboot the machine with the new video card. Try and save your comments until then! (gimme 15 minutes!)
Edit: done

tests are done.

It made it faster than i expected, but its gone from snail to snail on speed.


crossfiring two identical GPU's got an impressive (not) 30% speed boost. WOooooooo!

That's still really good for HTPC users. My HTPC used to be 780G+3450, worked awesome

well as the non crossfire tests showed, the 3200 onboard is just as fast as the 3450... and crossfire didnt change much.

i've always wondered how this would perform, thought about it for an htpc. especially since 3450s have low-pro and are are dirt cheap.

probably still better off just buying a better gpu lol.
