By now enough time has passed that I can come back here and hopefully answer/not answer a few questions :)

In the 8+ years I've been running this place, I don't think I've ever pulled an article before. I can't be too specific here, but some folks needed to be kept anonymous and I had to make a decision for the greater good in the long run. I apologize for remaining quiet about it for so long, but it was necessary.

With that out of the way - there's a lot to talk about.

I finally managed to pry a pair of 7800 GTXs away from Derek's hands and I've been working to answer the question of how fast of a CPU need to feed these things. There are a number of variables that have to be taken into account, most importantly being the resolution you're running at. The thing that's truly new about a card as powerful as the G70 is that you really start being limited by your monitor in what resolutions it supports. While owners of large analog CRTs have a lot of flexibility with what resolutions they can run at, LCD owners can't; so if you've got a G70 hooked up to a 1600 x 1200 panel you'll have to make different CPU decisions than if you have a 1920 x 1200 panel. I'm trying to simplify the decision making as best as possible and for this round I'm only focusing on single card solutions, but if there's demand later I can tackle SLI requirements.

I finally hooked up the G70 to the 30" Cinema Display and gave Doom 3 a whirl at 2560 x 1600. What I find most interesting is that once you start getting far above 1600 x 1200 it's no longer about making the game look good, it's about making the game look good on your monitor. For example, there's not too much difference playing Doom 3 at 1920 x 1200 vs. 2560 x 1600, it's just that the former looks great on a 24" monitor while the latter looks great on a 30" monitor. The quest for perfect image quality stops being about resolution and starts being about screen size; almost in a way similar to how consoles used to be, where your only hope for a "better" picture was to go to a larger screen, since you couldn't control resolution.

The pendulum will swing away from ultra high resolutions as games become more and more demanding. There are still some titles that even the G70 can't handle at above 1280 x 1024.

Monday's Athlon 64 Memory Divider article has got me thinking a lot about multitasking and its impacts on higher speed memory. Theoretically there should be some pretty big differences between DDR400 and DDR500 once we get into the heftier multitasking scenarios, but I want to get an idea of exactly how widespread that need is. My initial tests only revealed one scenario where there was a tangible performance boost, but I think they warrant some additional testing. After I'm done with this memory divider stuff I'll head on to that.

Many of you have asked for a Battlefield 2 CPU scaling article and I'm more than happy to oblige, so I've started working on the planning for such an article. Right now I'm stuck trying to figure out how best to make it a manageable benchmarking task, as I'd like to be able to provide accurate CPU/GPU recommendations for each performance class. I think I'll inevitably have to limit what GPUs I cover, but I'll do my best to include the ones you guys want the most.

I've been stuck on a H.264 kick for a while now, so I figured that doing a CPU comparison involving H.264 would be something interesting to do. My only question, other than Quicktime 7 and Nero, what are you folks using to encode H.264 on the PC?

Remember Gigabyte's i-RAM from Computex? Well, one should be in my hands very soon and given the interest in it, it's going to receive top priority as soon as I've got it. Which begs the question, are there any particular tests you all would like to see? I'll admit, I am a bit surprised by the positive response the i-RAM received; I expected people to be interested in it, just not this interested in it.

    Anand,
    Is it safe to assume the Sony/MS suits gave ya a ring? Would this be FAR from the truth (in that it was more of a personal decision) or had it been "made to your attention"? Sorry for the 20 questions, just extremely curious. You have NEVER pulled an article. (I've been reading your site since 97-98ish) Hopefully all is well, and we soon won't be seeing an Anand v. Sony/Microsoft court case any time soon....

    Any insider news about a real video card like R520?

    "...was threatened him..."

    Nice copy editing there! Take out the "him."

    Generic law question here. Is it considered slander to publish negative information as though it were fact, when the information cannot be proven because the source of the information is anonymous -- and thus unverified / heresay?

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    This whole situation reaks as though Anand was threatened him with legal action unless he substantiated his assertions (i.e. revealed the anonymous source(s)).

    Best of luck to you on this, Anand.

    In regards to H.264, its use in iChatAV3 on Tiger seems to be of mixed results. My guess is that while H.264 reduced bandwidth, it increased CPU load, such that some people with older systems are reporting image quality to actually be worse with the new version of iChatAV 3, vs the iChatAV 2, which uses H.263, I believe.

    So not really a benchmark item for H.264, but maybe something for the 'ramifications of H.264' section.

    The things I'd like to see for i-RAM:
    1. Database benchmarks
    2. RAID 1 "iRAM with hard drive" benchmarks - this strikes me as an interesting configuration
    3. SATA I vs SATA II benchmarks (or, more specifically, 3gig vs 1.5 gig bandwidth)
    4. Boot-time benchmarks

    There will be more coverage of the new consoles, I'm afraid I can't say much beyond that on the issue at this point.

    Take care,
    Anand

    "DDR200 memory is the fastest that is supported"

    Can the i-ram be overclocked and does it even help to have faster lower lat. ram?

    So are you going to get back up a somewhat revised article? i mean, this is important information and you made some pretty hefty claims about how the CPUs just suck. I have to say i wasnt very surprised - you get what you pay for, and when a system costs $300...
    The article has been copied and recopied all over the internet. if MS or sony wants to get at it, thats not exactly a problem. so you should either back up your original claims or take them back, not stand in some sort of weird limbo in between...

    Anand there was an interesting disscussion on Ars about Windows and its virtual memory subsystem this [url=http://episteme.arstechnica.com/eve/ubb.x/a/tpc/f/...]post in particular[/url] is relevant as the i-RAM was mentioned and the poster DriverGuru seems to work for MS or at least knows quite a lot about the team in MS who handle that part of Windows anyway his assertion was that you'd be better off outfitting Windows with 2GB of RAM then using the i-RAM to avoid paging to the hard disk, I'm curious to know if that holds true if you can test something like that.
