Latest reports from Chiphell suggest
that AMD would launch their Radeon HD 8000 series in Q3 2013, the site
also mentions new specifications of the upcoming graphic cards which
might stir up some interest of AMD fans since they haven’t seen a true
successor for the Southern Islands based HD 7000 series since over a
year.
AMD Radeon HD 8000 Series Launching in Q3 2013?
Previously, it was mentioned in a roadmap
by AMD that their HD 7000 series would be kept as a primary focus till
Q3 2013 after which they would probably release a new generation of
graphic cards. All was good until NVIDIA planned to launch their GeForce
700 series in May 2013 with the GeForce GTX 780
rather than pushing them to Q4 2013 as was rumored earlier. AMD
currently have nothing in their sleeves to tackle the $649 GK110 monster
known as the GeForce GTX 780 and only a few days later would the green
side also introduce another GeForce 700 series product “GeForce GTX 770” which is expected to be 10% faster than AMD’s fastest Radeon HD 7970 GHz edition GPU.
But these current reports from Chiphell suggest that all is about to change. You may remember us talking about the 20nm AMD Volcanic Island series
which was rumored to launch in Q3/Q4 2013. Forget that, the 20nm part
may not happen since the HD 8000 series is again going to be based on a
28nm manufacturing process but the codename might be “Volcanic Islands”
since “Sea Islands” is currently being branded for the mobile and 7000
series SKUs such as the HD 7790.
AMD Radeon HD 8970:
Well according to the reports, the Radeon HD 8000 series would kick
off with the launch of the Radeon HD 8970. The Radeon HD 8970 would pack
36 compute units resulting in 2304 stream processors, 144 TMUs and 48
ROPs. To tackle the GK110 rivals such as TItan and 780, the card would
be equipped with 6 GB of GDDR5 memory which would operate along a
384-bit interface and clocked at 7000 MHz effective. The core clock
would be maintained at 1100 MHz though whether or not Boost tech would
be available is unknown. Still this is 100 MHz higher than the GHz
edition plus is based on a newer architecture codenamed “GCN 2.0
Curacao”. The compute performance is mentioned at 5.07 TFlops which
would mean that overall the HD 8970 would offer 35% performance lift
over the HD 7970 GHz at a price of $599. The price may look high but it
was the obvious choice for AMD since the cost that would take to
manufacturer a chip to compete GK110 would cost alot and at the same
time AMD had to make sure that they don’t go the Titan route by pricing
the card higher since GTX 780 offers Titan-like performance for $350
less price.
AMD Radeon HD 8950:
The other three cards mentioned include Hainan 28nm based HD 8950
which is based on a totally different architecture than the HD 8970. We
are looking at a GTX 780 and GTX 770 like scenario over here. One card
is based on a high-performance compute chip while the HD 8950 sticks to a
lower-compute performance chip with a new name. The GPU features 3.5
Billion transistors and 8 Asynchronous Compute Engines compared to four
on first GCN architecture. Specifications include 1792 stream
processors, 112 TMUs and 32 ROPs while clock speeds are boosted to 1.2
GHz for core and 7 GHz effective for the 4 GB GDDR5 memory that operates
along a 256-bit wide interface. It would cost $399 US and bring 10%
better performance compared to the HD 7970.
The next two cards HD 8870 and HD 8850 are based on disabled variants of the Hainan chip which can be seen below:
