AMD showed the press the 'hammer'
Even if only behind closed doors, but at least for the press, AMD showed its new 'hammer' CPUs. In addition to some unlabeled CPUs, runnable systems were shown that ran Linux in 64-bit on the one hand and Windows XP in 32-bit on the other.
On the 64-bit surface of SuSE Linux, 32 and 64 Bit application in parallel. In the background, the computer still functioned as a web server that streamed data to nearby laptops. Script-controlled Office applications ran on the 32 bit Windows XP. Unfortunately, AMD did not comment on the clock rates of the models on display. However, we were assured that they were currently right on schedule and that the Clawhammer would be launched on the market at the end of the year. The Clawhammer represents the future desktop CPU for high-end users, while the Seldgehammer is set to conquer the server market. According to AMD, the Clawhammer will be 20 to 30 percent superior to the Athlon XP with the same clock frequency and in 32-bit applications. If the applications are designed for the 64-bit instruction sets, a performance increase of between 30 and 40 percent should be expected. The Clawhammer has 754 pins and the Sledgehammer 940 pins on the underside. AMD does not yet know exactly what the appropriate socket will be called. You can announce your suggestion for the Clawhammer in our current survey.
As some of you already noticed when looking at the pictures There are some changes to the board layout and to the processor itself. The hammer will have a so-called heat spreader, which has been in use at Intel for some time. On the one hand, it protects the DIE from external damage and, on the other hand, the heat is emitted over a larger area.
The heat sinks now also have a Rentention module to the side at AMDprovided, which is used to attach the heat sink. In the model shown, it was connected to the mainboard at the rear by a very large iron plate. This mounting method can still be revised, as AMD informed us.
In addition, AMD also uses the ATX12V specification for the Hammer, which is used in Intel's Pentium4. The 2x2-pin 12 volt connector provides a better and more constant power supply to the processor.
In addition, the memory management of the Clawhammer is integrated directly into the CPU and communication with the Southbridge takes place via a HyperTransport pipeline. This pipeline should also make it possible to connect up to eight CPUs directly to each other and not have to go via the northbridge.
There is also news in terms of overheating protection: The Clawhammer is integrated via an Temperature probe, which automatically switches off the processor in the event of overheating and is supposed to protect it from damage.
It should be understandable that the Clawhammer will initially be in a different price segment than the Athlon XP.
