AMD Radeon HD 7000 Series to be PCI-Express 3.0 Compliant

AMD's next generation of graphics processors (GPUs) that will be branded under the HD 7000 series, are reported to be PCI-Express Generation 3 compliant. The desktop discrete graphics cards will feature PCI-Express 3.0 x16 bus interfaces, and will be fully backwards-compatible with older versions of the bus, including Gen 1 and Gen 2. Motherboards sold today feature Gen 2 PCI-E slots, although some of the very latest motherboards launched by major vendors feature PCI-Express 3.0 slots.

The new bus doubles the bandwidth over PCI-E 2.0, with 1 GB/s of bandwidth per lane, per direction. PCI-Express 3.0 x16 would have 32 GB/s (256 Gbps) of bandwidth at its disposal, 16 GB/s per direction. AMD's next generation of GPUs, codenamed "Southern Islands" will be built on the new 28 nm process at TSMC, and will upscale VLIW4 stream processors. Some of the first PC platforms to fully support PCI-Express 3.0 will be Intel's Sandy Bridge-E. Whether AMD's GPUs have hit a bandwidth bottleneck with PCI-E Gen 2, or is AMD trying to just be standards-compliant, is a different question altogether.Source: Donanim Haber

nV was the first with DX10, but there wasn't exactly a slew of awesome DX10 games raining on us at the time, or even now, either. Your point?
AMD advertised DX11 as Eight World Wonder. Lots were fooled.

I think that his point is that being first to any of these technologies is pretty much irrelevant. Just something the marketing department will try to use.

The real point is that if neither pushes the envelope we'd still be AGP, Dx8, single 1280x and still be thumping our chest saying I get great fpS's.
Innovation I never say it’s not welcome.

only thing i don't like about this new stuff is i doubt it will have xp drivers or be xp compatible :twitch::cry:
your still using XP?......:wtf:

How many times I heard "Physx is dead", "Cuda is dead".?

I'm betting on "standards compliant".
I am going to say this is my guess too, I would bet it will be at least 8 if not 9 series before it actually makes use of it and not just compatible.

If this is true ASRock is going to sell a shitload of boards because of it.
I don't know about that atm current cards don't make use of full 2.0 bandwidth, I can't see selecting a board for single or SLI / Xfire based solution based on PCI 3.0 support or lack there of. I'd take the 2-3 FPS hit and go with things that matter to me more like the number of SATA ports and UEFI support.

Hey, I use it for legacy stuff. The machine barely gets turned on.

My comment was directed at the people who still use it as their main OS and refuse to upgrade.
It would break alot of my bussiness software to do so and cuase some serious issues in terms of machine performance. there was nothing really all that wrong with XP@SP3

The new AMD GPGPU arch GCN aims to kill it with a open standards compliant design.

Cuda will be dead when this rolls out or it will become massively less important and more specialized and as AMD is going put this design into APU's in the next 2 years, yep. Cuda is a dead man walking.

Now if nvidia was smart, they would move to standards compliance.

I thin CUDA is far from a dead man walking, especially in the super computer world, it's the standard. PhysX on the other hand is and has been dead IMO for some time, there has just not been a break out title that supported it mainly because all major titles are console ports, and as such CAN'T support PhysX, and it will continue to be that way until the next gen consoles come out. IMO Nvidia should have simply offered AMD a licensing agreement, and offered "incentives" to game developers to use PhysX.

As it stand I don't see CUDA going anywhere for a long time, especially for distributed computing (F@H anyone) and super computing applications. I just don't see the point in offering a competing standard to PhysX as it's a dead market, the problem is game developers outside of the RTS and MMO genres have turned their back on the PC platform, and the hardware they develop for is the better part of half a decade old, and can't handle good graphics let alone PhysX.

Does this supply anymore power to the card than pci ex 2.0?
From the PCI-SIG FAQ on the PCI-e 3.0 Specification ...
Q: Does PCIe 3.0 enable greater power delivery to cards?
A: The PCIe Card Electromechanical (CEM) 3.0 specification consolidates all previous form factor power delivery specifications, including the 150W and the 300W specifications.

I'm still running XP too, I don't see Vista Service Pack 3 (aka Windows 7) as an upgrade. Everything I want to do on my computer, I do great on XP. Smooth as butter :)

So this means we could see 6 or 8 pin plugs on mobos to add power over PCI ?

It's an upgrade trust me especially when you take into account M$ is going to stop adding security updates for XP.

XP = No DX11

I like XP but would never go back to it. X64 XP was buggy as shit

But XP is a pile of bloated shit. That and you automatically lose as much video RAM you have from your main RAM.

That and no DX10/11.

I am actually excited to see what the power draw of the 7 series will be, perhaps AMD can get it's drivers in order by then.

Meh lack of DX 11 is still not really an argument given there is maybe barely 2 dozen games that support it.

http://en.wikipedia.org/wiki/List_of_games_with_DirectX_11_support

I count 22 games

I wouldn't be worrying over DX11 anytime soon, I would worry about when will us the peeps get 64bit games

64 bit is the only thing that can maximize DX11 graphical/gameplay output

-----------

PCI-e 2.0 -> PCI-e 3.0

Expect that SLi or Crossfire jitter/stutter to disappear

I was off by 2 games :ohwell: , I agree DX11 isn't a big deal yet but I think 2014 will eb the year of DX11, as that is the rumored year for new consoles.

There's not a single game that I'd like to play but can't due to me using XP. I played through Crysis 2 fine. Mostly I just play TF2.

I also find it funny that you call XP Bloated, while at the same time push Windows Vista SP3.

there isn't a vista SP3 :confused:

if you mean windows 7 thats as far from bloated as you could get, had it running on riva TNT's and MX440 based rigs last week

After having to use Both XP and windows 7 on about 25 different machines each in the past 2 weeks i can tell you windows 7 is infact not very bloated at all

Xp starts off quicker but then the updates come and slow it right down

How is this On topic at all?

i'm just hoping PCI-E v3 is a sign the next gen cards will actually be able to use that bandwidth

That is referring to 7.

Well, let me see... When XP was first released, you could run it on a machine with 64MB of RAM, now with all the bloat it's accrued over the years you need at least 1GB.

Pre-SP2, Xp x64 was a nightmare to work with, both do to problems with the OS, and for limited driver support. However, by SP2 the OS was quite stable, and the Vista x64 push really brought quite a bit of driver support.

I really was sad to move away from XP x64, as it was truly my favorite of the Microsoft Operating Systems (low resources, 64bit, familiar interface, Server 2003 kernel, very fast).

I used XP x64 and the only issue I had was lack of compatibility. Even then, it was just Microsoft adding incompatibility flags to installers when the software itself had no problems at all.

It won't
but will the GPU cards perform better?

Yes

How and where it will perform better we will find out
