rofl cant deside on new hardware

[Sam DeathWalker]

The RevoDrive family gets its edge by eliminating the SATA II (3Gbps) bottleneck and leveraging a PCIe x4 interface to exploit the full potential of current flash technology, delivering superior speeds over 730MB/s sequential speeds and random small file writes up to 120,000 IOPS, nearly triple the throughput of other high-end SATA based solutions. Like the original RevoDrive, the X2 uses an onboard RAID 0 design, but it also employs four SandForce-1200 controllers versus two in the original to maximize data access and bandwidth.

Although its 4 lanes (I was thinking of the old revo) its still only 730MB/s, thats about 1.5 lanes.



Well if you don't render at full screen with IsBoxer like lax suggests then that is a Huge difference (320 X 240 instead of your full screen resolution). Ya if you give up mouse broadcasting and instant swaping then I am sure you will be fine. Im only talking about when you use IsBoxer in the mode where it renders all the tiles at full resolution. If you render 24 of them at the low resolution you will be fine. Giving up mouse broadcasting is no big deal but instant swaping? I can get to any of my 36 guys in under 2 seconds (7 clicks as fast as I can press the button), isn't that kind of important?

You run 15 tiled with isboxer at full resolution (i.e. instant swaping and mouse broadcasting) with your current system? In a battle ground or Dal. I find that very hard to belive.


Well again I did say it would be nice to know the exact amount of data that is require for textures for a full player character to exactly know what is needed to transfer.

And again I hope I am wrong but I still don't belive you can get textures fast enough at 730MB/s to feed 25 full screen renders, I guess if you had a video card with 3 outputs and takes up one slot, and had 2 or 4 SSD's in the other slots then ya maybe you could.

Assuming the use of three multi-gpu cards, we get an (optimum) bandwidth setup of x16/x8/x8, so the first card gets 8GB/s and the other two get 4GB/s. Again, I don't see that getting pushed to the limit. Even accounting for the four "lost" lanes from the card, (we'll just make every card run at x8 for simplicity), we're left with four "open" lanes of bandwidth.

Its not that you will run out of lanes its that your SSD is going to deliver 730MB/s (1.5 lanes), Sure the video card will take 8GB/s if it is getting its data from the system ram, but thats not going to be the case given the texturs will be on the SSD drive (unless some really good system ram caching is going on). Again the SSD drive is the bottleneck.

Well you can try these video cards the high end has 6 monitor output and 4G on the card:

This has three outputs but might not support all three (the above chart says 2 but it clearly has 3 outputs and the discription says 3).

The point being if you can get your 3 outputs on one card you might have enough space for more SSD's.


Well $1000 for 4 monitor support and 2G:

The new build forum isn't planning on running 25 clients ....



To get things in perspective although this revo is TONS better then a HDD, and is the best SSD made (well for under $1000) its less then AGP 4X:

http://en.wikipedia.org/wiki/List_of_device_bit_rates

730MB/sec is like .75 of AGP 4X.

Thats a FAR cry from the 25.6 GB/sec of the X58 system ram QPI buss.

Like you can see from my other posts previosly I have always said that if you get 24G and can put the entire wow folder in System Ram you will have zero texture lag becuase you have that 25.6GB/sec transfer from system ram to the video card and before 4.0.1 you didnt need an SSD IF you had 24G of ram (and are 5 or 10 boxing). BUT after 4.0.1 we can't get all of wow into the system ram because its to large .....

If you can go to 36 or 48G ram ya ... lol ... but ...

If blizzard would divide up the texture data into low res textures and high rez or maybe by expansion or somehting and say if you are in Wotlk you just load all the Wotlk textures into ram we could get by with 24G.
