Phenom II X4 955 has employed 45nm processing and Socket AM3. Clocked at 3.2GHz (16*200MHz), it’s coming with 2MB (4*512KB) L2 Cache and 6MB L3 Cache. With 125W TDP, Phenom II X4 955 is said to be launched on April 20th.

AMDs Phenom II processors are truly mean overclockers under extreme cold, but with more conventional cooling the processors are yet to really impress. They are still much better than the last series of Phenoms, but compared to Intels Core architecture they are still several MHz short. AMD overclockers have started looking for The Golden One among Phenom II processors and we now hear about a Phenom II X4 processor that does 4.4GHz with air cooling and "only" 1.55V.
The overclock was with all four cores, but and the air was a bit colder than normal (processor temperature was about 25°C) and the memories downclocked to reach 4.4GHz. The system was just stable enough for a CPU-Z screendump but it still shows that the Phenom II architecture can reach respectable frequencies with regular air cooling.
AMD’s dual-core Sempron X2 2300 has been available in Japan at JPY2480 (about $27), according to the guys at AKIBA. This is the second model of Sempron dual-core CPU after Sempron X2 2100 announced in last March.
With 512KB L2 cache, 65nm Socket AM2 and TDP of 65W, Sempron X2 2300 is almost the same as Sempr
on X2 2100. But it features frequency of 2.2GHz, up from 1.8GHz on Sempron X2 2100.

The specifications seem to be locked and Athlon X4 615 will work at 2.7GHz, come with 2MB L2 cache and will sit under the 95W umbrella.
The runner up is Athlon X4 605 that runs at 2.5GHz. Funny enough, the Athlon X4 605e works at 2.3GHz but has only a 45W TDP while the non e version has a massive 95W TDP.
At least you can expect these CPUs in back to school period.

AMD looks like it is a spent force today, pretty much like how its graphics arm, ATi is compared to Intel and NVIDIA, respectively. Still, kudos to the folks at AMD for keeping some semblance of check and balance in the processor wars. AMD will be working on a processor to penetrate the low-cost PC market which is currently being dominated by the Intel Atom and Via Technology Nano processors. These new offerings from AMD will support 6-bit instructions and based on their previous generation K8 architecture. You will get a capped speed of 1.2GHz in the single-core model, manufactured under the 65nm process. If AMD were to stand any chance of making an impact, they’d best price it just below Intel’s Atom IMHO.

Initially we came out with Close-to-Metal, which was a very low level interface. You had to know a fair bit about the GPU to use it, [but] you could get very good performance out of it. What we've done in the two years since we came out with CTM, is come out with higher-level tools. So, last November we launched Brook+, and what that is a C-level interface that is quite similar to [Nvidia's] CUDA and the OpenCL standard that's been proposed by the Khronos working group. So, it's kind of the same level, and the effort of Khronos is to try a standard API so that people don't get locked into one hardware platform or another based on initial software investment.
Intel may be gearing up to release Centrino 2, but let's not forget its arch-rival, AMD, is to release a notebook platform of its own, codenamed 'Puma'. The cat will be let out of the bag at Computex, in Taipei on 3 June.
So what's AMD going to announce? Puma comprises a new (ish) processor, 'Griffin', and AMD's 780M chipset. Griffin is a dual-core part based around a couple of old Turion 'K8'A-class cores. Unlike existing Turion chips, Griffin was design specifically for laptops and so features extra, mobile-friendly circuitry for better power management.
Indeed, power rather than performance is Griffin's watchword, though we expect it will still push past AMD's current mobile CPUs when the speeds and feeds are announced in June.
Griffin is expected to contain at least 2MB of L2 cache, with each core having 1MB all to itself. The two cores will be able to run at different clock speeds, allowing either or both to slow down - as far as 300MHz - when their workload lightens.
Griffin's northbridge circuitry combines the usual HyperTransport 3 controller and a DDR 2 memory manager capable of handling 667MHz and 800MHz memory, AMD has said in the past. These elements and the CPU cores all operate on separate voltage planes, to allow unneeded components to power down.
So if the 780M's DirectX 10 integrated graphics is churning through HD content, the CPUs can slow right down or go to sleep without affecting the memory controller's ability to keep the GPU fed with video data.
Likewise the bandwidth made available by the HyperTransport controller can be squeezed according to need, reducing the power required to support in-bound data, out-bound data or both.
The 780M's graphics core will work with a discrete graphics chip, if one's present, to render all the basic stuff and leave the main GPU to power right down until its needed for 3D rendering. Again, that should boost the battery life of Puma-based systems.
The 780M - or, possibly, the M780 - will also incorporate AMD's SB700 chipset, which can link in up to 14 USB ports, six SATA ports and parallel ATA devices, and provide HD audio.
A once touted Puma component was HyperFlash, AMD's answer to Intel's TurboMemory: a Flash-fitted module that provides a small chunk of solid-state storage for Windows Vista's ReadyBoost and ReadyDrive technologies to make use of.
Turbo Memory is available in a fair few top-end notebooks, but it's largely failed to grab attention as a performance booster that Intel may have hoped it would. Partly that's because of corporate indifference to Vista - though this may change now Service Pack 1 is here, and AMD is likely to want to tap into that with HyperFlash.
Support for HyperFlash is integrated into the SB700.
