Preinstalled Graphics. It is OEM only.
That would explain some things. Also, do the listed features fully match the 285?
The R9 380 is a renamed R9 285 with up to 4GB:

Well gg amd, hardly knew ya!
Tonga isn't necessarily bad but using what seems to be a 270 gcn1.0 and 260 gcn1.1 is just unbelievable. RIP amd 2015.

R9 360 has 12 Compute Units (768 Steam Processors) with up to 1.05GHz and it doesnt need an extra 6-pin. That means its only a 75W powered from PCIe alone.
The 360 and 380 may be respins of GCN 1.2 to lower the power consumption. The 370 looks like it is the same as 270.
Where does it say it is Tonga ???
Also,
R9 360 has 12 Compute Units (768 Steam Processors) with up to 1.05GHz and it doesnt need an extra 6-pin. That means its only a 75W powered from PCIe alone.
For comparison, R9 255 only has 8 Compute Units (512 Steam Processors) with up to 930MHz, same Memory bandwith and it needs an extra 6-pin power connector making it a 150W Power card.
And, R9 370 has 16 Compute Units (1024 Steam Processors) but it has memory bandwidth of 179 GB/s and only a single 6-pin.
R9 270X has 1280 SPs with 104 GB/s memory bandwidth and dual 6-pin connectors.
I dont believe those are just rebrands.
Edit: I believe 370 could go against GTX960
Its just a version.
Lets look on the 370.
"%AMD6810.1%" = ati2mtag_R575, PCI\VEN_1002&DEV_6810&REV_00
"%AMD6811.1%" = ati2mtag_R575, PCI\VEN_1002&DEV_6811&SUBSYS_0B001028&REV_81
"%AMD6811.2%" = ati2mtag_R575, PCI\VEN_1002&DEV_6811&REV_00
The chip is the same R575. Ids under and over matches the 270. Note I only posted 3, there are too many to post for Pitcairn.
The info that device manager would show:
AMD6810.1 = "AMD Radeon R9 200 Series"
AMD6811.1 = "AMD Radeon R9 370"
AMD6811.2 = "AMD Radeon R9 200 Series"
Same applies for the 360 for example. Its the R505 chip, a less used chip:
"%AMD6658.1%" = ati2mtag_R505, PCI\VEN_1002&DEV_6658&SUBSYS_293C1462
"%AMD6658.2%" = ati2mtag_R505, PCI\VEN_1002&DEV_6658
"%AMD665C.1%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C&SUBSYS_29321462
"%AMD665C.2%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C&SUBSYS_29341462
"%AMD665C.3%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C&SUBSYS_293B1462
"%AMD665C.4%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C&SUBSYS_8770148C
"%AMD665C.5%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C&SUBSYS_9260148C
"%AMD665C.6%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C&SUBSYS_9260174B
"%AMD665C.7%" = ati2mtag_R505, PCI\VEN_1002&DEV_665C
"%AMD665D.1%" = ati2mtag_R505, PCI\VEN_1002&DEV_665D
"%AMD665F.1%" = ati2mtag_R505, PCI\VEN_1002&DEV_665F&SUBSYS_0B041028&REV_81
AMD6658.1 = "AMD Radeon R9 260"
AMD6658.2 = "AMD Radeon R7 200 Series"
AMD665C.1 = "AMD Radeon HD 8770"
AMD665C.2 = "AMD Radeon R9 260"
AMD665C.3 = "AMD Radeon R9 260"
AMD665C.4 = "AMD Radeon HD 8770"
AMD665C.5 = "AMD Radeon R9 260"
AMD665C.6 = "AMD Radeon R9 260"
AMD665C.7 = "AMD Radeon HD 7700 Series"
AMD665D.1 = "AMD Radeon R7 200 Series"
AMD665F.1 = "AMD Radeon R9 360"
Actually, that's the funny thing. The 270 has 1280 SPs, so this implies that the 370 will be slower than the 270!
At price parity, the GTX 960 and R9 285 are very evenly matched. The R9 285 has a slight advantage in the overall FPS average, but it falls behind the GeForce GTX 960 in our time-sensitive 99th percentile metric. We've seen the reasons why the R9 285 falls behind in the preceding pages. I'd say the 99th percentile result is a better indicator of overall performance—and the GTX 960 leads slightly in that case. That makes the GTX 960 a good card to buy, and for a lot of folks, that will be all they need to know.
In virtually every case, you'll pay more for the Radeon than for the competing GeForce in other ways—whether it be on your electric bill, in terms of PSU requirements, or in the amount of heat and noise produced by your PC. The difference between the R9 285 and the GeForce GTX 960 on this front is pretty dramatic.
Something had to go to remove 1 PCIe connector and reduce TDP. Clocks are up slightly tho to with +50Mhz. Tho listed as Up to.
The 270 already only has a single connector dude.
