AMD Phenom II X6 'Thuban' and Phenom II X4 'Zosma' Tabled on Roadmaps
A list of new Phenom II series processors were tabled in a company road map. The road map confirms AMD's naming scheme for the Phenom II X6 brand, and also sheds light on a new line of quad-core processors. In the second quarter of this year, AMD will introduce Phenom II X6 six-core models 1075T, 1055T, and 1035T. While the 1075T has a TDP of 125W, the 1055T comes in 125W and 95W variants (likely one following the other), and 1035T is the slowest model with 95W TDP. All Phenom II X6 models are based on the Thuban core (a desktop, socket AM3 implementation of the Istanbul die). Each of the six cores has 128 KB of L1, 512 KB L2 caches, and a 6 MB L3 cache is shared between all cores. The HyperTransport 3.0 interconnect operates at 4.8 GT/s.
The new line of quad-core processors here, is the Phenom II X4 900T series. The first member in this series is the Phenom II X4 960T. These processors are created using Thuban dies by disabling two cores. It helps AMD salvage its foundry produce with minor defects, and also target lower price points. The resulting die is codenamed "Zosma". Zosma in X4 960T has a TDP of 95W. Probably it has a lower clock speed than the "Deneb" Phenom II X4 965, but is placed in the same league, in terms of performance. One of its biggest "unintentional" unique selling points is that since it's based on a die that has six physical cores, some customers could get lucky by unlocking them to a six-core processor, at a much lower price-point. Even as several motherboard manufacturers have innovated ways to unlock disabled cores, and are advertising their unlocking features, it is not guaranteed that a Zosma would unlock into Thuban, just as Callisto/Heka to Deneb unlocking doesn't always work out. Going by AMD's road map, these processors will be released some time in May.

all updated road maps show ddr3 only support for all upcoming chips
I take 4 core with each core being more powerful any day, especially being a gamer.
From what we know the highest clocked 6-core is @2.8Ghz, and a presumeably @2.2Ghz 1035T doesn't look impressive at all for even $250.
and the reality is in applications that does not support Hexa-core (which is still the majority), the I7 simply pulls a head and that is no contest.
The PII only pulls ahead on some game because of its signicantly higher clock speeds,
with the 6-cores the clock speeds are keep low to maintain that power envolop.
This is why AMD is implanting the Turbo Boost approach to minimize this set back.
Are the going for a new architecture or just increasing clockspeeds and cores on the current phenom II procs?
What we know is that 32nm is not tied with Bulldozer.
This means we might get 32nm CPUs before 2011, and are likely to get 32nm Phenom IIs first.Google is not always your friend, I am quite sure some idiot will say Bulldozer is based on Fermi. :p
Google is your friend when it helps you reach a reliable source.
Anyways, @2.4Ghz will put the 1035T somewhere near the i5 750 in terms of processing power, depends on how AMD manage to do their C-state clock boost.
Maybe AMD is just building 8 / 10MB CPU's and cutting those with faillures towards a lower cache level. There's always a faillurerate with a wafer, hence the X3 or X2 what was basicly an X4.
I'd like the sound of a 65W X2 @ 3GHz.
Do you know if AMD made more tweaks to the core architecture? Meaning clock for clock will the newer one be faster than the current PII? Or is it just sticking extra cores in there in one package?
Is it on 32nm or still 45nm? Sorry kind of behind on this lately.
