Just a question comparing X58 chipset to the new Z77 chipset for IB.

post #1 of 11
Thread Starter 
Alright so I am thinking about upgrading to IB when it comes out, but I am a little worried about something when I upgrade.

Right now I have a graphics card and a PCIe sound card. If I use both on the Z77 chipset will the CPU be limited to 2 x8 PCIe 3.0 lanes? Right now my computer runs the GPU at x16 and the sound card at its max of x4 since the chipset of X58 is 2x16 PCIe 2.0 or any combination of anything smaller so long as the motherboard has the slots for it.

Basically what I am asking is will there be a loss in performance or will I have to not use my sound card if I want to keep x16 PCIe 3.0 on the GPU? I am not even using SLI and it seems a little silly for someone to have to give up some GPU power just because they have a PCIe x4 sound card. frown.gif

I know the difference between x16 and x8 is minimal but it might turn out to be more when the PCIe 3.0 graphics cards are released and I do not want to have to upgrade my motherboard if I decide to upgrade to the next gen GPU in the future just because I have a sound card and upgraded to IB.

The difference between PCIe x8 and x16 will be even more minimal with PCIe 3.0, considering that it's double what PCIe 2.0 was. So, your GTX 580 shouldn't even take the slightest performance impact.

Alright thank you. Just to make sure I understand this though.

There is no way for the motherboard to run in PCIe 2.0 mode (not that I would want to) and have more lanes so with my sound card and GPU the GPU will run in PCIe 3.0 x8 mode which is about as fast as PCIe 2.0 x16 since 3.0 is twice as fast as 2.0 (considering that all lanes are utilized under maximum data transfer speed). The sound card will get its full bandwith needed at x4 so it will be fine.

Also, just out of curiosity, what if I want to get a second graphics card in the future? How would that work with Ivy Bridge (if it would work at all)? Sorry for these simple questions, I just want some confirmation regarding what would happen so I can plan my next upgrade to either IB or save up for the whole year and get IB-E early next year or late 2012. smile.gif

I know I really would not benefit as much with a CPU upgrade instead of a GPU upgrade, but surprisingly Starcraft 2 drops below 60FPS sometimes even on medium settings in large battles and that bothers me. Unless Starcraft 2: Heart of the Swarm has 4 core support I would like to upgrade. Since I really only plan on playing that and Diablo 3 when it finally comes out the GTX 580 should be more than enough to handle both games.

I know that what I just said in the last paragraph may seem a little weird to you but I am just very picky about the settings my games are at and my FPS so that makes me a very picky upgrader as well. redface.gif

It's a bit of confusing math. If you were to get two graphics cards, where would the sound card go? Given if you only had two x16 slots, and didn't have an x4 slot?

Well the sound card is a PCIe x4 card, so as long as the motherboard has a slot for it then how would that work? It is the Xonar STX if that helps at all. Would the graphics cards run in x8, x4 with the sound card at x4 or would the motherboard physically not support me plugging all those cards in at the same time?

I'm going to take this from a Sandy Bridge context. P67 (Cougar Point) has 8 PCI Express 2.0 lanes coming from the chipset. These support up to 5 Gb/s each lane (.8GB/s unidirectional I believe).

The Processor itself has a total of 16 PCI Express 2.0 lanes for use with the graphics card(s). Each of these lanes provide 8 GB/s.

338

So if you plug your GTX580 in right now it will be using the PCI Express 2.0 lanes from the CPU itself.

Plugging in the PCI-E sound card, in your case the Essence STX which is a 1x card (although the card will fit into a 16x slot). To much knowledge ALL sound cards only utilize 1x. Think about it this way even with perfect bit-streaming through ASIO with DTS-HD Master Audio which is an 8 channel lossless format you are utilizing 24.5 Mb/s. Compare this with a figure of 5000 Mb/s for EACH PCI-E lane. (this can also be verified by the width of the slot)

On the topic of PCI-E 3.0. The extra bandwidth is accomplished by upping the frequency not by any difference in the physical slot. Plugging a 2.0 card like the GTX580 into a 3.0 slot would only get you 2.0 speeds.

Outside of parallel computing even the 7970 sees no real benefit from going to the higher bandwidth of 3.0, since cards have VRAM not THAT much information needs to be shuttled over the bus. This is not the case with compute on GPUs because data needs to be transferred from the GPU to the CPU often and at low latency.

Edit: Note that the Sand Bridge PCI-E controller is more efficient than that of X58. Looking at benchmarks x8 SLI on the Sandy Bridge boards will give x16 SLI on older boards a run for their money, sometimes even coming out ahead.

This is not the case with compute on GPUs because data needs to be transferred from the GPU to the CPU often and at low latency.
Edit: Note that the Sand Bridge PCI-E controller is more efficient than that of X58. Looking at benchmarks x8 SLI on the Sandy Bridge boards will give x16 SLI on older boards a run for their money, sometimes even coming out ahead.

Alright thanks for the explanation, but I am wondering that since my card is 2.0 (sorry if I forgot to mention that I knew that) will it have x8 2.0 speeds on a 3.0 board or will it run just as fast as it would with x16 on a 2.0 with only x8 on a 3.0 board since the board is capable of 3.0 speeds. Also sorry for the x4 sound card thing, I don't know where I got that from but I do know that it is the smallest PCIe lane you can use, I just thought it was x4 since there are x8 and x16 lanes it must have registered as being needed to be divisible by 4 for some reason. tongue.gif

I am only mentioning this because in your post you seem to think that I do not even know what a PCIe slot on a motherboard looks like. redface.gif

Although you also answered my question as well I believe. So even if I plug it into the 3.0 board, since the card is 2.0, it will run as fast as x8 2.0 with the sound card plugged in. HOWEVER since the motherboards are getting better PCIe controllers it would up the speed to probably equal to that of x16 2.0 anyways, correct?

I know this is kind of a mess so sorry about that. redface.gif

A 580 does not saturate 16 lanes of PCI-E. The difference between a 16x slot and 8x slot would be less than 2 percent. However, as I understand it plugging a PCI-E 2.0 card into a 8x 3.0 slot would not yield any benefit.

Didn't mean to sound condescending. Just trying to thoroughly explain why pragmatically a sound card could not possibly need more than one lane of PCI-E to operate without issue.

The PCI-E controllers responsible for graphics cards are on the CPU itself, the chipset doesn't have many lanes at all. I didn't mean to imply that they are somehow getting more bandwidth out of the same lane, it's just perhaps things like latency drop and small inefficiencies make up for the lower bandwidth of a 8x slot.

As it stands if you use a P67 board with 1 GTX580 the GTX580 will get 16 lanes of bandwidth and the sound card will get 1 through the chipset.

If you plug in 2 GTX580s the cards will get 8 each and the sound card will get 1 through the chipset.

If you have 3 GTX580s it becomes fairly messy and it may be worth it to invest in X79 and/or a board with NF200 chips to multiplex the PCI-E lanes.
