AMD Announces OEM Desktop Radeon 300 Seriesby Ryan Smith on May 6, 2015 8:20 PM EST

Along with today’s announcement of the OEM mobile Radeon M300 series, AMD has also announced the OEM desktop Radeon 300 Series. This was a rather low-key launch with only a very brief press release on the matter along with AMD updating the OEM Radeon website, and as one might expect this is for good reason.
We’ve been through this event once before – most recently with the OEM HD 8000 series – so our regular readers will know the drill. Whether or not GPU manufacturers have new GPUs, OEMs will want new parts to sell, which leads to GPU manufacturers engaging in rebranding and subtle spec changes to create new parts to sell under a new series name. In AMD’s case this is complicated by the fact that they have been updating their GPUs in a piecemeal fashion – Hawaii, Bonaire, and Tonga have all landed at very different times – and AMD is not done yet as they’re going to be launching a new high-end GPU this quarter. So AMD needs a product lineup to include both the new part and their retained parts under a single brand, which leads to another incentive for rebadging.
In any case, as these are OEM parts I advise not reading into the names and specifications too much. AMD’s OEM and Retail parts can be very different at times – and at other times there aren’t any retail parts at all (HD 8000) – so these OEM parts aren’t necessarily indicative of what we’re going to see in retail in the coming months. Though based on AMD’s actions with the Radeon 200 series, we may yet see a similar rebadge happen for the retail 300 series.

Starting things off, we have the OEM R9 series. Today’s release tops out at R9 380 OEM (I can only imagine AMD is saving 390 for their new GPU), along with the R9 370 OEM and R9 360 OEM. The R9 380 OEM appears to be a variant of the desktop R9 285, which marks the first time that a Tonga card has been released in an OEM configuration. The quoted clockspeeds are identical to the retail R9 285, which means the “up to” GPU clockspeed should result in the R9 380 OEM being perfectly identical to the R9 285 if given its maximum configuration.
Meanwhile for the R9 370 OEM we have a cut-down Pitcairn card, with only 1024 of its 1280 SPs active. This makes it a variant of the retail R7 265, though with a slightly higher maximum GPU clockspeed. Truth be told I’m a bit worried to see a fresh Pitcairn part in 2015; Pitcairn has been a workhorse for AMD, having now survived into its 4th generation of cards. However at over 3 years old and based on GCN 1.0, it lacks more modern functionality such as the ability to decode 4K H.264 video files, AMD’s improved power management technology, and support for AMD’s Freesync technology.
Finally we have the R9 360 OEM. This appears to be a variant of the R9 260 OEM, featuring an AMD Bonaire GPU with only 768 of its 896 SPs enabled. Oddly, the listed memory bandwidth for the part, 104GB/sec, would require 6.5GHz GDDR5 memory given Bonaire’s 128-bit bus. I suspect that may be an error on AMD’s part, though it’s not outside the realm of possibility. In any case the R9 360 OEM also appears to be a regression from the R9 260 OEM; the latter was a fully enabled Bonaire part, whereas this one is not. At the very least it’s GCN 1.1 based, so it will have the newer features that the Pitcairn based R9 370 OEM lacks.
|AMD OEM Desktop Radeon R7 300 Series|
|AMD Radeon HD R7 350 OEM||AMD Radeon R7 340 OEM|
|Was||R7 250||R7 240|
|Memory Clock||<=4.5GHz GDDR5
|Memory Bus Width||128-bit||128-bit|
|Manufacturing Process||TSMC 28nm||TSMC 28nm|
|Architecture||GCN 1.0||GCN 1.0|
Up next is the R7 300 OEM series, which is composed of the R7 350 OEM and R7 340 OEM. Both of these cards are straight-up rebadges of AMD’s existing R7 250 OEM and R7 240 OEM parts, and both are based on the same GCN 1.0 Oland GPU. With just 384 SPs these are low cost, low performing parts. The difference between the two is their clockspeeds, with R7 350 being clocked quite a bit higher, whereas R7 340 is clocked lower in exchange for being available as a low-profile card. Unfortunately the memory situation is quite complex here, as these cards can be equipped with either GDDR5 or DDR3; the GDDR5 versions will of course be the much faster versions.
Among its other quirks, Oland lacks a hardware video decoder. So these parts are likely to be paired with low-end AMD Kaveri APUs, possibly for a Dual Graphics configuration.
|AMD OEM Desktop Radeon R5 300 Series|
|AMD Radeon HD R5 340 OEM||AMD Radeon R5 330 OEM|
|Was||Variant of R5 240||Variant of R5 240|
|Memory Clock||? GDDR5/DDR3||? DDR3|
|Memory Bus Width||?||?|
|VRAM||<=2GB GDDR5/DDR3||<=2GB DDR3|
|Manufacturing Process||TSMC 28nm||TSMC 28nm|
|Architecture||GCN 1.0||GCN 1.0|
Finally, for the R5 300 OEM series we have two more Oland parts. These are ultra low end, low-profile single slot parts. AMD does not even publish the GPU bandwidth numbers for these parts, and as a result I suspect these may be 64-bit parts to further cut down on costs. Of particular note, the R5 330 lacks HDMI support, so it’s almost certainly geared towards APAC markets where VGA is still in common use.
Wrapping things up, AMD's press release mentions that these new OEM parts are shipping now. HP is already confirmed to be shipping PCs with these new cards, and we expect other OEMs to ramp up as well as they launch their back-to-school season computers.

dragonsqrrl - Wednesday, May 6, 2015 - linkWait, so I guess this means Fiji won't be called the 390/390X? Will AMD skip to the 400 series for their next lineup? Or will they go with a new naming convention?
Wreckage - Wednesday, May 6, 2015 - linkSo 380 = 285??? That has to be the worst rebadge ever.
CaptainDoug - Wednesday, May 6, 2015 - linkThe 285 outperforms the 280x on 1080p results but falls behind when it comes to higher resolutions due to the lack of vram. If they bump it up to 3 or 4GB it should be a decent performance improvement.
takeship - Wednesday, May 6, 2015 - link"Outperforms" is damning with faint praise in this case though. ~+10% performance and ~-10% power use up against a 3 year old architecture (HD7970) is not much to write home about. Especially since it's arguable that most of the power savings came from simply lopping off part of the memory bus, and failed to improve video decode power use. More realistically, how many OEMs are actually going to stick a ~250w card in their desktop products? This just seems like a card in search of a market.
ET - Thursday, May 7, 2015 - linkYou must have missed the 370 = 265 above. If there's a worst rebadge award, surely it must go to it.
MrSpadge - Thursday, May 7, 2015 - linkAgreed - I was expecting this rebadge round to be really bad, but this still shocked me. They have an underperforming, uncompetitive expensive GPU, held back by low clock speeds (using high voltage nevertheless) being sold in a cut down configuration. Yet they do not even bother to improve it in any aspect but still give it a number upgrade.. *shaking head*
Creig - Thursday, May 7, 2015 - linkWrong. The R9 380 OEM is a variant of the R9 285. We don't know the specs of the RETAIL R9 380 yet.
chizow - Thursday, May 7, 2015 - linkSo much defense of all these rebrands Creig, is this good for the consumer, in your opinion? :)
silverblue - Friday, May 15, 2015 - linkHe's only saying that the retail 380 isn't the same thing as the OEM 380. Wreckage is partly justified in his comment in that this article is discussing the OEM products, but in a wider sense, the retail 380 is more likely to be a rebrand of the vanilla R9 290, and as such a completely different animal to the OEM 380.
I will also point out that there wasn't an OEM Tonga card before now (as far as I'm aware).
Now, the 370... pour your scorn on that one, it's time Pitcairn died a death.
WinterCharm - Thursday, May 14, 2015 - linkIt still doesn't match the price/performance I get from an nvidia card :/
