dual PCIE 16X + P4 640 on dell?!

Yeah, exreteme tech benchmarked the Dell Dual 16X Sli vs FX-57 standard SLI(8X). The Amd machine wooped Dells(Intels) butt hands down. The crazy part is some people are still going to buy that overpriced POS when the could have built a system for half that(or less) and it would be even faster. <A HREF="http://www.extremetech.com/article2/0,1697,1845022,00.a..." target="_new">http://www.extremetech.com/article2/0,1697,1845022,00.a...;/A>

Interesting sutff!

Its sure that Dual 16X wont bring much if any over 8X as 8X is already twice as fast as agp8X, I seriously doubt it will be a bottle neck for some time to come!

lol what happends if AMD FX-57 + dual 7800GTX at PCIE16?

it happens the same thing as Fx57 + dual 7800GTX at PCIe8

i that that more band wideth = faster interface and faster card?

My guess that a FX-57 with Dual 16X PCI-E board would only do a little better than the current 8X Pci-E. 8X Agp wasn't even throttling video cards so super fast bus speed at this point is a waste. I'm sure they'll have a good ole marketing scheme saying how 16X is way cooler than 8X and how you should buy it. I'll just sit back and watch the dumb sheep buy it. I'm sure down the line a full 16X bandwidth may be reached but we are a long way off from that right now.

i thought that a PCIE vid card could handle about 40 GB/sec transfer? as in one article it said that current vid cards could make about 40 GB/sec transfer and that PCIE 16 was only 8GB/sec max... someone correct me? i try and find the article

unh?

My guess is we'll need at least 2 more generation to completely saturate the PCIe16X...(just a guess).

As of right now no video card even comes close to the full 16x PCI bandwidth. Granted I don’t have any numbers or links to back my statement up but there is one thing I can mention. Take a video card like the 6800GT AGP and the PCI-E variant. When the clock speeds are set the same the performance difference is negligible between the two cards even though the bandwidth is twice as high. (AGP is 2 GB/s and PCIE 4 GB/s one direction, while Bi-Directional is 8GB/s for PCI-E) . A normal Sli system is at 8X which is still fast enough for the current generation of cards. Who knows how long it will be until a full 16X speed can be attained by a video card

Does this mean that AGP is only half duplex?

O.o...

Agp allows Bi-Directional transfers but its in half-duplex mode. Check out the link below, it will make things clearer I think.

Wow, the max upstream transfer rate is only 266MB/s for AGP 8x...you learn summik new every day.

Ya, but that's from the card to the cpu. 266MB is more than enough for VIVO.
Even the 7800 cards dont need anywhere near 2.1 GB/sec. unless we are talking Sli totals.

Yeh but what about transferring textures back to main memory, at some point they are gonna need to swap textures. 128-256Meg can only hold so much and those large texture files have to go back sum where.

Most cards have a special, large cache, just to deal with large texture files (I think)

Yeh but at some point these textures are gonna need to be discarded back to main mem or swap file (the graphics card can only hold so much. Surly if its a large texture and the bus is only half duplex then this is gonna take a lot of the bus's time.

DELL + Gaming Machine = 1 big Laugh. Unless that DELL comes with water cooling then WTF are they thinking going Intel for gaming.

PS. We all know why Dell chose Intel so god bless the hopelessly inept that chose this system.

Compaq S5000nx
yes the one with an asus mobo and non exsistant apg slot. It was free so dont yell at me LOL.

Well, the last time I checked, a 512 meg card had like five hundred and twelve megs of memory. Not that the newest cards can use that much, but still, it is there for when cards do get fast enough to make use of it. Any system memory that does get used, is done by the cpu, not the gpu, so the upstream bandwidth just isn't needed.

No, PCIe x8 is slower than AGP 8x. The big numbers you hear are because it's full-duplex, so it's capable of that same rate in both directions simultaniously.

PCIe x1 is ~250MB/s, both ways, so you'll hear 500 even though for devices like video cards it isn't. AGP 1x is 266MB/s and has all those cute AGP features.

Oh thanks for clarifying that! I knew these where full-duplex numbers, but I still beleived it was faster downstream and upstream.
I stand corrected!

Yes, it's 2 gigabits in each direction per lane, which is ALMOST twice as fast in each direction as PCI is in one direction. AGP is 2x PCI, per "x".

PCI-X right now because of card availability. PCI-X over x1 in the near future because of 133MHz/64-bit roughly equivelent to x4.

For the future? As cards become available, x1 and x4 of course.

x8 is rediculous for anything but graphics. All the x8 cards I've seen would work just as well on x4.

hmm cheap 8X gfx cards?

Unlikely, there aren't any boards with x8 slots. There are boards with x16 slots that have x8 pathways...

PCI-X is faster. 66MHz/64bit is 4x as fast as PCI, PCI-E x1 is about 2x as fast (but bi-directionally it's about 4x as fast).

i thought that I-RAM used SATA as data transfer and PCI as power

BTW check other... i will forgive you because you helped me a lot throughout my upgrade (and hope more in the future), but common pointing out specific names is not that nice....

Geez, I thought PCI-X covered several standards including 66/64 and 133/64. OK, 133/64 is 8x PCI, simlar to PCI-E x4.

PCI-E x2 would only come close when both directions are at full capacity, any offset to either direction would find it lagging behind.

O.o well i don;t really point at someone and say [insert bad thing here] i just have problems with grammer and spelling, likes to get quick responses so that i post my question in a more populated forums. This is most likely because i'm somewhat impatient, hence the speedy crappy replies with about 10 edits, also i got this habit from the d2 forums as that in there if you are slow even for one second then a trade or something is gone, and that the more people see your post either by legit reasons or by alternative names (cachy names, or outright lie) the more chances that you will achieve your goal sooner. I do realize that this isn;t the D2 forums, but someties a habit (even good) is hard to get rid of, so bare with me, and in time i will change (seeing that i will no play during school time and that now that my PC is better i could try some nice FPS, and no more trade hijacking or anything).

I hope that you understand that i'm trying to change my habit, and that i will try to put out more posts like this one in the grammatical and spelling sense, i'm sorry if my rushness have offended you, but i am mad at being pointed out and picked on, especially behind my back.

i would just like a uniform standard, as that i hate to have some special features missing on one type of standard, or having mobos that only support one type (because of size of slots or conflicting hardware or something) and that less people will become better at computer because of the complexity of choosing one.

well guess i'll try my luck there.

Hmm, I thought all the 64-bit slots for 66/100/133 were under that title...

Anyway, 133/64 has TWICE the bandwidth in one direction, but similar bandwidth bi-directionally.

And x4 SHOULD be replacing it, except some companies think they "need" to promote x8 instead

x4 SHOULD be used more frequently due to the number of pathways available on most chipsets.
