DELL Inspirion 5675 - Radeon RX 570 or RX 470?

They are both RX 570.  Different makers set clock speeds and voltages to different settings.  Some may under clock.  Some may over clock depending on power requirements and the cooling systems they use.

If you installed the 2 cards you show results for in the same system you would see almost no difference in game play.  Maybe a frame or 2.  I am guessing the reason the Dell card is set the way it is is to keep it cooler and more stable.

It's not only memory clocks that are equal to RX470, but the release date, pixel rate, texture rate and bandwidth too. Weird, don't you think?

New pics from AIDA. AIDA identifies the GPU as an RX470 or RX570, depending of what you select on Display:

There is same problem here.

All indicates there is a RX470 with a replacement of bios to change the name of the GPU to RX570.

That was riddiculous, instead, Dell support on Facebook ask for wait 7 days to analise the case.

Add this to the fact that the motherboard doesn't work at 16x PCI-E, and we have a minimal of 15% loss performance compared what the Inspirion 5675 suppost to be.

I really want to know, what Dell will do to fix it.

I'm also impacted by this "mistake" from Dell.

I bought the same Inspiron 5675 version of @Fernandobnu, and I can confirm the same symptoms. The VGA is presented as a RX570, but everything points to be a RX470 with BIOS mod, to deceive the customers.

Here in Brazil, we pay a very high price for hardware parts, the minimum what we expect is get exactly what we bought.

Could anyone from Dell explain what is happening here?

X370 works on 1x16/2x8 (AMD Ryzen™). So, they have to work in 16x speed (like the specification that Dell sell us in the marketplace), this is not a trouble at all, an update bios can solve.

RX5xx séries use to be Polaris 20, not Ellesmere. They're selling us this:

Seems to be a little diference, but we don't pay for RX470. On techpowerup review, the diference between the cards reach 15% in some cases.

The AMD RX 470, 480, 570 and 580 all use the same graphics chip.  The only differences are how many compute units are enabled, core clock speeds, memory speeds and memory amounts.  AMD does not define minimum speeds so slapping a 500 series name on an older design is 100% fine. The best thing you can do is download a copy of MSI Afterburner and overclock your core and memory speeds to match what they should have been (no guarantees on stability).

As for the dual 8x PCIe slots it is noted in the AMD x370 specs.

The part I do fault Dell is this should have all been clearly shown in the system specs.

If you need one more thing to be mad about your processor might be defective.

same "issues" here. Is there ANY part of this computer that hasn't "unadvertised downgrades" or blocked functions? :|

Polaris 10, Polaris 20 and Ellesmere are all the same chip.

The X370 chipset can be wired 1x16 or 2x8.  To support both at the same time would require an additional logic chip that I don't think Dell included.  The problem is x16 can mean both physical support or transfer rate.  The computer does have physical support for two x16 cards.

Also I wouldn't expect a BIOS update to add support for the Ryzen 2 processors coming out Q1 2018.

I have the same issue with my Inspiron 5675 which included the RX580. It seems the specs are the same as the RX480. Also, in 3DMark, it tested as about 15% slower than most other RX580's and is identified as an RX 480 in some screens. Looks like they went as cheap as possible to ensure I never purchase a Dell again.

Lostsavage, as I said, I bought the desktop DELL 5675 with RX570, not an RX470 with the name modificated to RX570. I will not do an overclock to frye my system. Dell needs to resolve this.

About the 16x PCI-E, I use only one video graphic card and the system still appoints to 8x. This is another issue from this pc.

They are re-flashed chips.  Check your manufacturing date or the SKU on your card.  I agree that this needs to be made right - but after my 3 week endeavor they said, return/refund or get over it.  They said the advertising is correct according to them (my chip date is 2016/ not 2017).  This includes the PCI-x8 3.0 issue.  

Has anyone been able to get a resolution from Dell on this?   They basically told me they had no intention of replacing the video card or compensating for the difference.  If you run the SKU/Barcode on the back of your card you'll have more information.  Mine was manf. date of 2016 - Ellesmere not Polaris 20.. HWid64 says rx480 chipset.  Also, the 6 pin power connector is a dead giveaway!  The rx580 takes an 8pin with power usage at 200-225watts - not 150 watts.

Here is a different way to look at.  If you were to ask AMD if these are cards are real RX 570/580 cards they would say “Yes”.  That would be the end of the story for getting anything from Dell.

A more interesting question is to ask AMD if these cards 100% follow the RX 470/480 reference design and they would also say “Yes”.  Note that doesn't negate the above question and answer.

If you are not happy with the computer and are still in return window then definitely return it.  Make sure you give them all the reasons like the video card is below the specs from other manufacturers and PCIe slot does not have x16 throughput.
