AMD's upcoming Radeon HD 8000M "Solar System" line of mobile GPUs, which are slated for a CES 2013 launch, were detailed in a press-deck scored by Engadget. According to the slides, the Radeon HD 8000M is based entirely on the new Graphics CoreNext (GCN) micro-architecture, supports DirectX 11.1, and AMD's equivalent of NVIDIA Optimus, the Enduro Technology, which dynamically switches between discrete and integrated GPUs, which coupled with AMD ZeroCore power technology, completely turn off discrete GPUs at low graphics processing loads.



With the Radeon HD 8000M series, AMD appears to be introducing a new ASIC to cover three product lines - HD 8500M, HD 8600M, and HD 8700M, by tinkering with specs such as clock speeds and memory type. This silicon features 384 GCN stream processors, and a 128-bit memory interface, supporting GDDR5 and DDR3. The HD 8500M series features GPU clock speeds up to 650 MHz, while the HD 8600M up to 775 MHz. Memory clocks for both lines can go up to 4.50 GHz (GDDR5) and 2.00 GHz (DDR3). The HD 8700M series, on the other hand, ups GPU clock speeds up to 850 MHz.



AMD's second chip that makes up the HD 8800M series is similar in specifications to the current-generation "Cape Verde," which goes into making desktop Radeon HD 7000 series discrete GPUs. It features 640 GCN stream processors, GPU clock speed ranging from 650 to 700 MHz, and memory clock speed up to 4.50 GHz. In its press-deck, AMD compared the HD 8870M to NVIDIA's current-generation GeForce GTX 650M GDDR5, HD 8770M to HD 7670M (which is based on the dated VLIW5 architecture), and HD 8690M to the HD 7590M. The new chips, by AMD's own testing, are 20~45 percent faster than their competitors.



Perhaps AMD's winning strategy for the HD 8000M series is to leverage Enduro, ZeroCore power, and the GCN architecture's GPU-compute performance competitiveness over NVIDIA Kepler. Notebooks (and possibly all-in-one desktops) based on the new chips will launch over Q1-2013. In Q2, AMD will launch performance-segment SKUs in the lineup.

Don't really like some of this naming convention. One of the pictures shows that an HD 8700M can be clocked identically to an HD 8500M (and all the hardware is identical), and still be called the 8700M.

What incentive does a manufacturer have to list their notebook as having an HD 8500M, when they could 'correctly' (according to that image) call it the 8700M instead, even though it is weaker than an 8600M?

No I think the product itself will automatically scale between the values shown. The OEM is probably not choosing within that range, lol. So the lower 3 chips seem differentiated by maximum clock speed, and the top one has more hardware.

What the hell, with such high number the performance doesn't make sense. 8800 to beat a 650? since when 8 means mid/low range? 4800M used 4800 desktop's chip, now 8800M using something comparable to a 7700's. Anticipating 9800M to use HD 8600's specs.

The 8000 series on the mobile side is a stop-gap generation for Richland.

I see, I guess I misunderstood it (thankfully).

I'd like an OEM to stick one of the mobile GPUs on to a PCIe card for a bit of silent low power HTPC.

this is way too confusing, x700 is getting a downgrade from 7770=512gcn to 8770=384gcn
and why are they comparing 8700-7600 and 8600-7500, thats just too confusing
however unless gcn2.0 is 20-25% faster clock-clock meaning this isnt a cape verde chip then the extra clock speed would make the difference but then their comparisons make you run into a wall

so idk how accurate these graphs are but this is what i came up with so far
cape verde 7770 at 1ghz has 1125sp gflops
the 8800m in this graph claims to also have 640gcn cores similar to cape verde running at max700mhz however rated at 992sp gflops, so if calclulated clock for clock you get about 20%-25% better efficiency for 8800m
this leads to the question, will richland use 384gcn cores for perfect scaling or 512gcn cores?

either or if my calculations are close to reality I think performance wise they probably remained pretty constant to last gens x600 x700 and x800, but with lower consumption and smaller chips/lower cost(except for the 8800m which is probably higher performance for same chip size and power consumption)

Tock. Tick was the HD7000 series.

New - HD5000
Refresh - HD6000
New - HD7000
Refresh - HD8000

HD9000 will be again new, most likely. Then they'll have to look into a new naming scheme because they'll run out of current numbering scheme numbers.

Did you read the article? It says Radeon HD 8000M. Which would mean that these are mobility Radeon GPUs.

yes i know, the mobility radeon hd7730m-7770m had 512gcn cores- while hd7800m had 640gcn cores
so what i was saying 7770m has more gcn cores than 8770m
to me that sounds like a downgrade, unless they do some magic with tdp and clockspeed/memoryspeed
but even so i hardly see the 8770m beating the 7770m, maybe it would be as fast for lower tdp
