Official S754 vs. S939 A64 Thread
Since we have so many decent threads in here, that have been completely overrun with this topic, I think it needs it's own thread.
To get started, we need some volunteers that have similar systems to compare :)
What we need:
A) S754 CH 1MB with a 9800 Pro or XT
A) S939 NC 512K with a 9800 Pro or XT
B) S754 CH 1MB with a X800 Pro or XT
B) S939 NC 512K with a X800 Pro or XT
C) S754 CH 1MB with a 6800 GT or Ultra
C) S939 NC 512K with a 6800 GT or Ultra
Benchmarks to be run:
- 3DMark2001 game tests (give compare link)
- Super_Pi 1M
- Pi_Fast
- 3DM2003 game tests and CPU test
- Aquamark game tests and CPU test
Please post some other CPU related benches / gaming benches to stress cache and memory bandwidth (dual-channel).
So we don't have to depend on the multies of the chips that will be compared, let's run each bench at these speeds:
8x200 - 1.60GHz
8x240 (166 Mem Divider) - 1.92GHz
8x267 (150 Mem Divider) - 2.14GHz
8x300 (133 Mem Divider) - 2.40GHz
And finally 8xMMM - (MMM will be the slowest maximum memory speed between the two systems being compared. If one system's memory can do 240MHz, and the other 260MHz, a test should be run on both setups at 8x240 (no memory divider).)
Memory timings will be kept the same. If the memory being compared is different, try and use an equivalent timing. IE: BH-5 that does 2-2-2 vs. CH-5 that does 2-3-2. Both setups should run 2-3-2. If we are comparing EB vs. BH-5, run the EB at 2.5-2-2, and the BH-5 at 2-2-2 to try and minimize any differences there.
WindowsXP - DX9 - Latest official drivers (CAT 4.7 for ATi) (61.77 for nVidia). No OS/Driver tweaks (detail settings all on high)
Video cards will be run at equal stock clocks. 9800Pro vs. 9800XT, run at 412/365 is fine if both cards are capable, 380/340 if not. Comparing an x800Pro vs. an XT shouldn't be done (unless the Pro is modded to 16-pipes, in which case run both cards at stock Pro clocks). Same goes for 6800 GT/Ultra, run both at stock GT clocks.
I'll try and compile the results after benchmarks have been posted and put them in this thread with individual tests differences and an overall % of which of the two chips were faster.
Let's also try and keep the S754 vs. S939 debate in here, so we don't keep running other threads off-topic :) (I know, i'm guilty of this)

Re: Official S754 vs. S939 A64 Thread
Excellent idea on this thread LilGator :toast:
Once results start to come in it will be very interesting to see the trends
I dont own either setup so this is jus my thoughts but I think the 754 will scale better as the memory frequency goes up... but I voted "About Equal" because from reviews I've seen the difference seems to be within a margin of error.
Reason I think 754 will scale better as RAM speed rises is that the 939's advantage over 754 is so much more memory bandwidth potential... but the CPU can only use so much bandwidth before the speed increases yield less and less benefits. The 754 has more to gain from increased bandwidth seeing as that's what it lacks in comparison to the 939... jus my opinion, wish I could contribute to this thread.
