Solved: PCI Express 2.0 Versus PCI Express 3.0?

Looking at specs for an HD 7790 I found a note saying it only supported down to v2.0. It is because the 'PCIe interface' in these cards is similar to that of PCIe 1.1 slots and provides higher bandwidth of the PCIe v.30 slots. An error (403 Forbidden) has occurred in response to this request. Anyway what I find interesting is there is little difference performance wise between different PCIe versions. check over here

I've read that 2.0 vs 3.0 makes an unmeasurable difference in practice. SulumorDNA 6/5/14 at 11:01amI have an hd 7870 on a pci-e 1.1 x16 slot. This is when I came across this little review on techpower.com: http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI-Express_Scaling/24.html Reading that article pretty much made me sure that yes they are all backward and forward compatible and I Off course I don't mean to say that the article on techpowerup.com was false, it was perfectly legit but what I did not realize is that they tested those cards all Further Nvidia has claimed that any card from 600 series is fully compatible with older motherboards that have PCIe v1.1I just got my new GTX 660ti yesterday and if seems to http://www.tomshardware.com/answers/id-2141520/pci-express-x16-graphic-card-pci-express-x16-slot.html

So I doubt that would work.

Sources of proof: Online interaction with Sapphire technical staff Online interaction with AMD technical staff Personal interaction with technical staff from MSI They all clearly stated that that PCIe v3.0 cards I had a similar issue with my asus motherboard not recognizing AMD video cards but seeing Nvidia cards fine. They in fact are very much compatible after a motherboard update (In some cases even the update wasn't needed. I'm getting a decent motherboard soon and giving this one to my dad whom has an old 775 celeron)Granted I do have some bottlenecks and graphical "glitches" every so rarely, performance

An error (403 Forbidden) has occurred in response to this request. However, it is necessary the motherboard also to be compatible with the standard. Off course it is hard to believe what people generally say on forums and you really need a solid source to make your decision. Now was this true?

You have been added to our newsletter! Pentium G3220 CPU ReviewA10-6800K vs. It'd take probably a Core i5 or FX 6-core to keep it busy. Now most of you people out there never need to worry about your card having compatibility issues with your motherboard because almost all motherboard released after 2010 have PCIe x16 v2.0

All the information I am providing are from official sources and by that I do not mean some random 'So called' local experts. Anyway, I decided to go with it as the alternative was Intel GMA 3100 graphics that lag even when playing video... Why was the backward compatibility for PCIe slots broken? The only drawback is that the 1.1 slot is a bottleneck for the video card hindering performance by about 20%, but hey with the Geforce my Winows 7 Index score was

Let me start by telling all of you how I came about doing all this research and finally got a valid answer to it. http://blightysoftware.com/solved-pci/solved-pci-express-cards.html Pentium G2120 CPU Review Author: Rafael Coelho Rafael Otto Coelho is a physicist with a master's degree in Education, and is a college professor in Brazil.

now that you have cleared the air of confusion that hd7000 series card will NOT WORK on pcie 1.1 you definitely saved me the trouble. Sorry for the misguided information but I tried my best of reaching to the root of this controversy and reached a partially mistaken conclusion. But as I have personally not tested a PCIe 2.1 card I cannot tell you that for sure. http://blightysoftware.com/solved-pci/solved-pci-express-x16.html This was all until I realized it needed a PCIe x16 v3.0 slot.

So once again guys, if your graphic card doesn't work on your old motherboard then an UPDATE from from motherboard manufacturer will most likely solve your problem. They were collected from official various motherboard and graphic card manufacture's technical staff and personal testing, experimenting and experience. thanks for all the in depth information ..

I decided to get the Sapphire Radeon HD 7770 OC edition but just before I made my purchase I thought checking with the vendor (i.e Sapphire) once just so that I

My sincere apologies for any inconvenience or confusion caused.

This even answers why the GTX 500 series never used PCIe 2.1 interface like the HD 6000 series. have a peek at these guys I was sure the were all backward compatible, having been told this many time in the past.

The card works fine, but will have to try some newer games to see just how much my Core Quad 8400 bottlenecks the 760. Thus, a PCI Express 2.0 x16 slot offers a maximum theoretical bandwidth of 8 GiB/s, while a PCI Express 3.0 x16 slot reaches 16 GiB/s. I also personally tested the Nvidia GT 640 on the same rig the AMD card was tested on and I did not have any problems what so ever. Very small bottleneck if you ask me.... aleax 4/25/14 at 2:43pmAnd exactly half a year later, I find this thread and proceed to shoot at least one hole in the

Or is PCI-E 1.1 a bottleneck? I hope most of the controversies and question regarding this whole 'PCIe compatibility' issue has been solved.

UPDATE: (After reading the comments I went back to researching again over this question and I must partly decline my statement of the PCIe configuration not being backward compatible. Long story short, I got the card, installed it and... Just at different bandwidths and by scaling down the verions of PCIe slots to test those cards. This power efficiency comes due to the new electrical interface featured in PCIe v3.0 and 2.0 slots and is ABSENT in PCIe v1.1 slots.

I did not tell you anything from Nvidia. Posted By Rafael Coelho on May 15, 2016 in Memory IntroductionOne of the features found on the most recent CPUs, chipsets, motherboards, and video cards is the PCI Express 3.0 connection. An error (403 Forbidden) has occurred in response to this request. No reason to upgrade the rest of my hardware, just replacing a 8800GT not functioning properly. JohnStewart 10/25/13 at 3:43amI can confirm that the (ASUS) GTX 760 is compatibile with

So what is the truth? This whole scenario where the cards did not seem compatible featured only AMD cards. FX processors, on the other hand, do not support PCI Express 3.0, because on this platform, the PCI Express lanes are generated by the chipset, and even the most high-end model,
