POSTER: computer news   ||   AMD BULLDOZER AND BOBCAT MICRO-ARCHITECTURES

DATE:2010-08-26

The micro-architectures Of bulldozer and Bobcat appeared since 2007. These micro-architectures are to a considerable degree related, but oriented for different markets. Bulldozer is intended for highly productive servers and PC, where it will compete in the following year with processors generation sandy bridge. Bobcat is, on the contrary, aimed at the segment of mobile and highly economical solutions, and it will be competitor  of Intel atom and VIA nano. Today AMD officially presented both micro-architectures.

We start from the elder micro-architecture bulldozer. This architecture is developed actually from zero and is not the evolutionary development Of k10.

Bulldozer is something qualitatively new,  it is even complicated to understand : the deeply integrated dual core or single core processor with the evolved analog of hyper-Threading technology .As explains AMD, this component is called module and includes two conditionally independent computational core and general blocks: the block of calculations, cache in the second level, device of sample and decoding of instructions, and also a number of other blocks.

What is the basic differences between bulldozer module from phenom and Nehalem core ? First, this is the already mentioned unique design of computers layout in the module, in essence tightly interlacing two core into one, which must increase the operation speed of multi-threaded tasks. In the second place, AMD adopted strong sides of competing micro-architectures Intel - the general for two core cache second level and increase in the number of decoder channels from three to four, which will allow it for one time to decode up to four (8) instructions against three (6) in K10 and four (5) in Nehalem. This will allow to better employ the computers module , which positively will affect the general productivity. On AMD assertions , the addition of second individual core with the collection of its own integral and address actuating elements increases the module area in all by 12%, but it it actually double productivity in a number of cases. In essence, this is the intermediate step between one core with virtual thread (Hyper-Threading), when two thread compete for the processor resources  , and honest dual core version, where will be observed the smaller load of actuating elements by one thread. Thus, it is possible to consider that the basic of  bulldozer architecture increase the productivity by transistor (in the same area). Also it is worthwhile to remember that at the disposal of module and two integral core will prove to be the powerful block of calculations, with AVX instructions support   .

AMD created powerful and well scaled computational micro-architecture sufficiently compact. It is hard to objectively estimate the operating speed. Even with the high heat emission and the low energy-effectiveness, most likely, it will be possible to manage, since the first models Of bulldozer in the form of  zambezi  core (4 modules), will be produced on 32 nm to technological process and use a system of the complete de-energizing of blocks (it is used by Intel in Core 2 and Nehalem).

Now let us check the micro-architecture bobcat. AMD promises up to 90% of productivity of usual processor during the consumption of 1-10 W.

The micro-architecture bobcat, in the essence, is the lightened half of bulldozer module. The processor do note support SSE4 instructions in all forms, AVX, and also 3DNow! The block of integral calculations was also deprived of excess part. The cache of second level with  512 kbyte volume will work at the half frequency of core. The number of decoder channels is reduced by two, in comparison with Bulldozer, but in this case are preserved the powerful blocks of branchings prediction and high marking speed and instructions sample, at the level of k10.

To a considerable degree Bobcat resembles to Atom, with the only difference that uses only more powerful computers, and also effective technologies of load , including extraordinary performance. Thus, actually there are all prerequisites for obtaining relatively high productivity during the minimum energy consumption. Bobcat is perceptibly faster than Atom.
