Intel's Pentium Extreme Edition 955: 65nm, 4 threads and 376M transistors

Gaming Performance using Battlefield 2, Call of Duty 2 and Quake 4
Gaming performance is pretty respectable for the Pentium EE 955, with the chip being quite competitive with AMD's Athlon 64 X2 4800+.
The most interesting thing we found is that even with a high end GPU like the Radeon X1800 XT, a number of games are still quite GPU limited even at 1024x768, which is why you don't see F.E.A.R. and Splinter Cell: CT here. Even some of the games that we did include required us to turn down some of the detail settings to start to stress the CPUs.
The pendulum often swings between games being CPU and GPU limited, and it seems that with the latest generation of games, we are definitely more GPU limited.

See above post. The 3800+ OC article has the BF2 benchmarks/tools in it.bob4432 - Friday, December 30, 2005 - link
thanks, i had just found that. excellent tool ;). what is the difference between average fps and actual fps?Spacecomber - Friday, December 30, 2005 - link
If you need more direction on how to go about creating and running a timedemo in BF2, take a look at http://www.overclockers.com.au/article.php?id=3841...">this article over at overclockers.com.au.The timedemo records the time it takes for each frame to be rendered over the course of the demo being run. It sums these times and divides by the number of frames to come up with an average. You end up with just one number standing in for a rather large collection of data. Some sites, such as hardocp, try to show more than just an average, usually by presenting a graph of the framerates over the length of the timedemo. This can be helpful, because when you are trying to evaluate how well a particular hardware setup will work with your favorite game, you really are looking to see whether it will maintain playable minimun framerates at the resolution and graphics settings that you want to use. An average alone only gives you a rough idea about this, though it does give you a quick and dirty way to compare different video cards in the same game setting.
If you create and run a Battlefield 2 timedemo and look at the complete results, you'll see how very wide the range of framerates is. For example, running the timedemo, I have gotten an average of 50 fps, but the range is from 2 to 105 fps, with a standard deviation of 12.3. Graphing out the individual frame rates will let you see how often the frame rates drop below 20 fps, for example, which many would consider too low for online gaming.
http://www.sequoyahcomputer.com/Analysis/BF2memory...">Here is a graph of a BF2 timedemo. It's for the data that gave me an average of 50 fps that I mentioned previously. Although 50 fps sounds like an ok average, looking at the graph, you can see that many might consider these settings on this hardware to be barely playable.

thanks, what program did you use to graph the data?Spacecomber - Saturday, December 31, 2005 - link
The full results of the time demo are saved in a csv file, timedemo_framerates.csv, which can be opened with a spreadsheet program. I used the spreadsheet program in OpenOffice to view the data and eliminate the framerates that are erroneously recorded before the actual gameplay demo has begun (they are easy to recognize, since they are at the begining of the data and unnaturally high), and I also used the spreadsheet program to graph the data.Space

I believe Anand is using the same benchmark that I http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">linked in my Overclocking article. He's probably running the 1.12 version now, which would account for the slightly lower scores than what I got with the 1.03 version and demo files. BF2 is VERY GPU limited, so even at 1024x768 you will start to hit FPS limits on high-end systems. You can see in the above page how FPS scaled with CPU speed on an X2 3800+ chip, and I only improve average frame rates by 18% with a 35% overclock at 1024x768. That dropped to 8% at 1280x1024 and less than 4% at 1600x1200 and above.danidentity - Friday, December 30, 2005 - link
Has there been any official word on whether or not 975X will support Conroe?coldpower27 - Friday, December 30, 2005 - link
a 975X Rev 2.0 is probably needed. However the i965 Chipser series for sure as they are rumored to be launched simultaneously.Shintai - Friday, December 30, 2005 - link
You gonna need i965 I bet for sure, specially if Conroe gonna use a 1333Mhz bus.However, Merom should fit in Yonah Socket (Conroe mobile part)

Every hardware site that has tested the power consumption and operating temps of Presler knows full well this is a 65 nano FLAME THROWER almost making the P4 FLAME THROWER look good by comparison. "Normal" operating temps of 80 C are OUTRAGEOUS as is equal or higher power consumption than the FLAME THROWING P4 series. And as the benches show -this is a Hail Mary approach by Intel to baffle the naive with B.S. No one with a clue would touch this inferior CPU design. And to add insult to injury, after the Paper Launch -- when they are actually available for purchase in Feb. or later, the asking price is $999. Yeah, I'll run right out and buy a truckload of Preslers to use for space heaters in my house...
