Sapphire Reference Radeon RX 480 Taken Apart, Pictured Some More
A Sapphire branded AMD reference design Radeon RX 480 graphics card was taken apart, giving us an early close look at the card and its key components. The pictures reveal pretty much the same details as the first close-up shot of the reference RX 480 / RX 470 common PCB, and the cooling solution was taken apart further, revealing more details than the first time we saw what's underneath.
To begin with, the reference RX 480 PCB features a 6-phase VRM that draws power from a single 6-pin PCIe power connector. Display outputs include one HDMI 2.0 and three DisplayPort 1.4 connectors. One of the pictures features a close-up of the 14 nm "Ellesmere" silicon. The cooling solution is confirmed to feature a chunky monolithic aluminium heatsink with a copper core, cooling the GPU, with a metal base-plate conveying heat from the VRM and memory to it; ventilated by a lateral blower. The Radeon RX 480 is expected to launch on the 29th of June, 2016, priced at $199 for the 4 GB variant, and $229 for the 8 GB variant.
More pictures follow.
Here you see the PCB up close, beginning with the 14 nm "Ellesmere" silicon. This chip appears to have a smaller die than, say, "Tonga," a similar package size, yet a higher transistor count owing to its smaller fab process. Next up is the 6-phase VRM with LFPAK MOSFETs. Lastly, it's revealed that the 8 Gbps GDDR5 memory chips on the card are supplied by Samsung.
Lastly, taking the cooling solution apart reveals a very simplistic design. AMD is taking advantage of the 150W TDP of the "Ellesmere" silicon, and employing a simple monolithic aluminium heatsink, with a copper core. There's no complex fin-stack, no heat-pipes. The metal base-plate transports heat from the VRM and memory chips onto the main heatsink, while itself dissipating some of the heat under the lateral-blower's airflow.

www.powercolor.com/us/products_features.asp?id=535Ah, it is smart marketing. I since seem to be evolving on the whole 3 chip Polaris thinking. The hope that there was still a full Polaris (40CU) is still there though not seeing the strong yields and they need to amass more good candidates; Or it's a Vega LE with just 4Gb of HBM and then a 8Gb, and then later a factory Fury that's pegged to via the GP102. RTG is probably considering having it in the market end of Oct more or less as a book end to Zen. They've got a whole 4 months to keep the marketing buzz building after Polaris, and still be there for Christmas. Heck most Christmas purchases at such a level aren't presents, but made with money received as presents.
That way I don't have to see you spouting crap in an amd based thread.
Just get two Amd pro duos or fijiX ,two Gtx 1070s or 80s and crack on wasting them on 3x1080p.
Polaris 11 = 16CU
Polaris 10 = 36CU (this was mistakenly reported to be 40CU at first based on the similar R9 390 performance)
Vega 10 = 64CU
Vega 11 = ???
You simple or just plain stupid?
This is maybe point less for you, but like i told you most of the market isn't you.
- Air intake on both sides
- Embedded Copper
- One-piece Heatsink
- No painting heatsink
- Four-wire fan for more precision

I unfortunately can't say that i expect any noteworthy performance from this cooler. It will be quite loud.
This will perform worse then AMD's current coolers.

Short pcb, with overhanging shroud + blower fan. 660, etc.
1070 also uses 4 pin PWM fans, just like RX 480,
the difference is 1070 uses separate cable for voltage (black-red cables) and RPM sense (tachometer)+PWM control (all black).the black+red cable is for GEFORCE LED on the top of the card, the 4 pin PWM fan is the all black cables :And one piece heatsink? Nope, both are similar kind of Al+Cu slab plus metal plate/bar to cool VRM & VRAM chips and mount the fan :
Personally I will be taking the 470 or 480 on a run in the HTPC system :)
220$ mid-end card won't beat high end for 400~450$, even with water cooling.
As for bling the ref 480X looks bland you nutter ,plain black shroud, now a 1080 has ally bling, get that.
