Reviews Arrive For nVidia GeForce 6600GT AGP
bhtooefr writes "The Tech Report got their hands on a reference board of the nV 6600GT AGP, and did some benchmarks. Interestingly, even with a slower memory clock on the AGP card, it was FASTER in some benchmarks than the PCI-E card. Tests performed were: Doom 3, CS:Source, Far Cry, 3DMark05, Rome: Total War, and Xpand Rally (the last two tested with FRAPS)."

Extreme Tech, Hard OCP and PC Perspective.
The main reason I see to move to PCI Express is that it is a fully open standard by the PCI Consortium, rather than AGP which is an Intel trade secret. It is because of this that AMD had horrible AGP support for a long time, but with the open standard that is PCI-Express everyone wins.
Plus you can daisy-chain multiple PCI-E cards for SLI, which is neat.

Mobo manufacturers still need to up the PCI-E bus bandwidth before we can daisy chain though. Right now there just isn't enough space for two cards, let alone two cards and other addons.
By the time thr prices drop there will be more information like this article on the differences / advantages of PCI-E over AGP. Think I'll wait until then before deciding on an upgrade.
>Anyone else wonder why PC gaming is dying off?
Yeah, I bet that's exactly what ID and Valve are thinking right now. And Blizzard. And SOE (allright, I also wish they were dead).

They got "Rome: Total War" to run? Wow!
A video card that will easily play Doom3 and HL2 and cost around $200. Of course this card has been out for awhile...but few people have a PCI-e board (Now it's a viable AGP upgrade).
Also worth noting is that the 6600 offers full support for Shader Model 3.0 and DirectX 9.0C, ATI does not currently offer support for this yet.

On the other hand Extremetech's review find the PCIe version much faster
Not true. Extremetech concludes "You can get nearly all of the 6600 GT goodness in an AGP package, and leave very little on the table."
ich muß mehr Kuhglocke haben
Even if the AGP version of the 6600GT outperforms the PCI express version slightly, there is still the value of the PCI ex version to function on the new SLI boards, whenever they come out.
The 6600 cards are pretty reasonably priced, so picking up two of them and getting 180% performance of a single 6600GT AGP is pretty attractive and a sufficient reason to drool over the new NForce4 boards(for the AMD enthusiasts among us).
The Current intel boards with SLI are considerably more expensive than the new NForce4 boards figure to be, so while there is still a few weeks till I can get my hands on one, I can't wait to get a pair of 6600GTs running in SLI mode with a respectable AMD 64 chip.
Concider this. I need a computer to do my job. It is a buisness expense. I write it off on my taxes. I build a new computer every july. I always build it on 3-4 month old technology (last july, i875p board p4 3.2ghz and 9800 pro) This july will be an amd64. I have never upgraded a pci, in fact when I sell my old pc's off they usually got another 1-2 years of video gamming without upgrades in them. Plus my return on investment is great. I spend about 1100 on a good pc. I usually get about 800-900 for the pc when I sell it. That makes the cost of my pc about 200.00. So, can I buy an play station 2, do my job on it (software development), browse the internet, play video games, use a keyboard and mouse, watch dvd's, burn dvd's and cdr's, Learn new operating systems with multiple partitions/hard drives, and keep myself on the edge of technology so my skills will be desireable for under 200.00? Oh yea, its got to be a tax write off too. ** Disclaimer, I own a ps2, psx, gameboy advanced, xbox, and gamecube. I bought the ps2 and xbox when I needed dvd players for my tv (hey why not), got the gamecube for christmas from my girlfriend, had the psx for years, and bought the gameboy for flights. I still play most of my games on the pc.
Interesting to note that Toms hasn't posted on this yet. I wonder how long they will take to get it to the review done to their satisfaction? Good for them.
TV in the US (NTSC) is at 59.94 fields per second interlaced, so it is equivalent to 29.97 frames per second. However, in Europe TV (PAL) is 50 fields per second interlaced, or 25 frames per second. The reason for the difference is the difference in the mains AC frequency on opposite sides of the pond. (The 60/59.94 disparity is due to a complication of colour TV). This has annoying consequences when transferring video, as conversion is required (also in terms of number of lines). Cinema film tends to run at 24 full frames per second, just to make things a little more complicated. Here is a comparison of TV formats.
Actually, I believe the way we percieve frames on TV, and on a PC screen are completely different. On a typical TV frame, the frame records motion. If you extract just one frame and look at it, you can see that the moving objects are blurred. 24-25 frames is actually what most *film* is recorded at. Movie films, I think, are still recorded at 24fps, that number was chosen because of a very old trade-off between running the film at high speed to get more frames, and running it at a low enough speed to stop the film from tearing.
On computers, you can most definitely tell the difference between, say 60fps and 100fps, because a frame does not record motion. One frame is just a statically rendered shot. But above that, you wouldn't notice too much difference.
That said, the actual reasons for upgrading your card wont be the FPS. It will usually be running it at a decent FPS while still keeping the newer features like Antialiasing, Pixelshading, etc turned on. Many newer games (DX 9.0+) rely on stuff like this to get anything done. Notice the detailed dynamic shadows in the D3 screens? Your GF4MX420 can't handle those very well I suppose?
But hey, I own a GF4MX440SE, and between putting up with the high costs of a new card and all the people who say I've actually bought a hidden GF2GTS, I'd choose the cheaper alternative any day.

Unfortunately for the PCIe users (and I am one, the new box that $EMPLOYER got me uses PCIe video) graphics are quite sensitive to latency.
I'm one of the SPICE trolls at $EMPLOYER who developed the I/O stuff for both AGP and PCIe. For what it's worth, I won't be switching to PCIe until it looks like I don't have a choice.
Lacking <sarcasm> tags,
am I the only geek who does NOT play video/computergames?
yes.
what other metrics can be applied to video cards?
length. weight.
That's PCI Express not PCI-X.
The parent is spot-on. Current AGP 8x bandwidth is 8x(266*8, 2128MB/sec), but the performance difference between 4x(266*4, 1064MB/sec) and 8x is negligable(around a percent, within experimental error). Considering that x1 PCIe is 250MB/sec, PCIe and AGP are effectively running at the same speed given the same multiplier. If you take in to consideration that we just said that we aren't making use of anything past AGP 4x yet, it's a logical assumption that PCIe x4 should also be enough, and that x8 would be enough for the next generation of cards that would somehow need the doubled bandwidth.
But getting back to the point, the current PCIe graphics standard is x16, which at 4GB/sec(and this is each way, BTW - PCIe is full duplex, AGP is half) is far more than we need. The current solution of dividing up the 16 lanes from that single slot in to 2 groups of 8 lanes for 2 PCIe x8 slots(though using an x16 connector for power issues) still results in each card recieving more bandwidth than it can effectively use. With a single x16 slot, PCIe is future-proof enough that bandwidth won't be an issue for some long period of time, and than the x8 SLI solution won't be bandwidth limited for some shorter, but still long enough period of time that it's not going to be a realistic issue until at least the 3rd or 4th generation PCIe motherboard chipsets are released, at which point they can be built with more lanes.
6 frames per second in The Sims 2, at least while you're moving the camera. Otherwise 160 FPS, when the camera is set. :)
Actually, if you read the article, you would see that the NV43 chipset that the 6600 uses is a native PCI Express chip, and they use a bridge chip to make an AGP version of the card. This is why PCI-E versions of the 6600 have been out for a while, but the AGP version just became available today.
From the first page of the article:
"The NV43, however, already has a built-in PCI Express interface, so for the AGP version of the GeForce 6600 GT, NVIDIA is turning the HSI chip around and using it to bridge between the PCI-E graphics chip and an AGP motherboard."
