I purchased a Dell Inspiron 5675 with a Dell labeled AMD RX580 GPU included. The specs on GPU-Z show it as having the same specs and bus speeds as the RX480. On HWINFO64 it shows AMD Radeon RX 580 [DELL], Polaris 10/Ellesmere XT, the Chipset 'AMD Radeon RX 480 Polaris 10/Ellesmere XT. Is Dell pulling a fast one here? How can I identify if this is truly an RX580 card?

Don't overthink this. A company like Dell isn't going to offer a fake product. GPU-Z has confirmed what you have. Sounds like the mystery is solved.

As previously mentioned, the RX580 is really (in a manner of speaking) a tweaked, slightly improved RX480. They belong in the same family of GPUs and the (likely) older hwmonitor database just doesn't reflect the most current info.

GPU-Z says AMD Radeon (TM)RX 580. Release Date Jun 29, 2016. Ellesmere C7, Device ID 1002 67DF - 1028 1701.

How can I tell if they put an RX 480 chip in the card and called it an RX 580? It's what it looks like to me. Shouldn't it have a different chip ID? With a different release date? Like this year?

Did you check the SKU on the back your video card? I ran mine and it actually showed up as an RX480. I called Dell and they have no intention of changing their marketing or advertising this correctly. Its fraud! The manufaturing date for the card is in 2016 - the rx580 didn't even exist retail/OEM yet.

I have the same issue and feel very bad. I bought Alienware Aurora R7 with dual Rx 580. They look like RX 480, with only one fan on top.
All the specs are the same with 480. The GPU_Z also shows the release date as 2016, the GPU is Ellesmere. What a big fraud !!

The 580 is 580, How could you say two cards are the same with different GPU clock? I care about the performance. The reality is Dell fools us with a cheaper option. I want a card with a better performance not a reduced freq. one.

Look at the specs if you don't believe me. Both the RX 480 and 580 use the same GPU, Polaris 10 "Ellesmere", configured with 2304/144/32 Shaders/TMUs/ROPs. AMD just took an RX 480 and overclocked it and released it has the 580. This is often referred to as "rebadging", and AMD/Nvidia do it all the time.

It's not unusual for monitoring utilities to report as a rebadged card as being the original model. Seeing as how neither you nor the OP have listed what frequency your cards are actually running at, nothing said so far in this thread necessarily indicates a problem.

Hi, Master. I did not mean that. I bought 2 desktops and got 3 so-called 580 cards. I am very concerned about their performances.They all operate at 1266 MHz, power limited by 110 W but Dell claims 150 W.
Each one comes with only one fan. I could say these cards do not have the competitive cooling performance and a much lower base clock frequency. I could also say the overall quality of these cards fall behind the normal 580?

Unfortunately I don't think it's uncommon for OEMs to reduce performance of cards to fit within thermal/power constraints. RX 580 TDP is 185W, so it makes sense they'd have to reduce clocks to try to fit in a 150W envelope. And the base clock of an RX 580 is only 1257 MHz, so technically you're still within RX 580 levels.

Regarding card/cooler quality, that has nothing to do with RX 480 vs 580, and everything to do with getting cheap OEM cards.

These are actually RX480's. I know that they are advertised as 580's but they are not. They are 480's with a hex edited bios to be 580's.

Easiest way to prove this is just flash an RX580 BIOS (I have tried about 5 now!) and then an RX480 BIOS.

Here are the results:

With any RX580 BIOS the card will not display anything. When booted into Windows you get error 43. Suffice to say that any of the 580 BIOS I tried all failed with this result.

With any RX480 BIOS, it flashes and boots just fine. Windows then picks it up as a RX480.

I then flashed the stock bioos back to the cardx and it booted back up as the hacked up RX580 that dell says it is.


These results are not scientific however they are pretty telling. Dell did some really shady things with the Inspiron 5675, including limiting the PCI X16 bus to only 8x (multiple complaints about this found by google search) and limiting the NVMe to PCIe 2.0 X4 instead of PCIe 3.0 X4. This one I found online as well and had to test, and yes, it is. So with this said... Yeah.. These really are RX480 cards!

I totally agree with you. I tried to install the rx480 driver, in the windows device manager, it will show as rx480. All the specs prove they are just 480. Shady things not only happen in Dell's 5675, but also in so-called high-end Alienware desktops.

Well, the device ID's, subsystem ID's, vendor ID's would match a 580 instead of the 480 that they are currently listed as in GPU-Z. Thats the first thing that would be different. Being able to boot with an actual 580 BIOS installed would be another thing I would expect to see... Performance wise, Im sure very little.

So you tried flashing a different vendors BIOS on to a DELL brand card.... You're about dumb. There is no gaming improvement using the x16 over the x8. This had been tested many times. You sound like a troll who lacks the intelligence to understand the phrase rebranded.

I have this exact same computer paid about $600 for it and it is the best GAMING bang for your buck. Super slow hard drive is my only complaint being this is sold with out the expectation of many upgrade options.

I can understand the concern, but they are essentially the same card. I had an RX 480 and they perform just fine. Also, they can look physically similar to the RX 580, so if they look the same it would be feasible that some 480s were accidentally used. That said, you are talking about a very small amount of fps at best. You are kind of splitting hairs here.

Also, the cheapest you are going to touch an RX 480/580 is close to 400 dollars by itself. By getting the card in your Dell you probably paid nowhere near that for it. Stop worrying so much about it and enjoy it because you probably got a great deal on it compared to others.

Also, why would you pull a stunt like trying to flash the card with a 3rd party RX 580 bios? If you brick the card by doing that do you think Dell is going to accept a return? I would not since that would count as modifying the system.

If this is that big a deal, then return the system.
