Powercolor HD3850 Extreme PCS - AMD 3850 Performance explored
Published: 15th November 2007 | Source: Powercolor | Price: £135 |Test Setup and notes
To test these high-end cards I set a PC that gives as little of a bottleneck as possible. The Test setup used for the cards is this:
CPU: Intel Core2Duo E6700 @ 3.33Ghz
Motherboard: XFX 650i Ultra
RAM: 2gb Mushkin XP2-6400 4-4-4-12
HDD: OS - 160gb Hitachi Deskstar SATA II
Power: Zippy 500w
Case: Silverstone TJ09
Cooling: Scythe Infinity
Call of Duty 4
Command and Conquer 3: Tiberium Wars
Bioshock DX (DX10)
UT3 Beta (DX10)
Crysis Demo (DX10)
I am using a manual run-through of the games listed, exactly the same as in previous reviews, but doing it slightly differently to get some consistant numbers. Notice that for all games unless stated I ran through with 4 x AA and 8 x AF @ 1920 x 1200. For all of the 3Dmark benchmarks I did two runs. One run was with the stock settings that the free version of the benchmark comes with and one was with 4 x AA @ 1920 x 1200.
For installation I have installed the card as usual with the normal PCI-E power dongle. Checked that the card is seated correctly and powered on.
I am using a clean install of Windows XP Professional SP2 with all the latest patches and a fresh install of Vista for those games/cards tested with DX10.
The Powercolor HD3850 was installed using the beta AMD 8.43 Vista driver set (inc CCC)
The 8800GT XXX Alpha Dog Edition card used the nVidia 169.02 Forceware drivers.
Note that the two Ultra cards were tested earlier using 173.71 drivers
The 2900XT card was installed with the Catalyst Control Center 7.9's.
