POSTER: computer news   ||   AMD PROPUS PROCESSOR CORE AREA	DATE:2008-12-22
It is known that Deneb processors (6 Mb cache in the second level) will not be the only representatives of phenom II architecture with four core. Besides the processors series phenom II X4 9xx, AMD company  intends to present in the following half-year the four core processors phenom II X4 8xx with 4 Mb cache in the third level, and also the four core processors athlon X4 6xx (Propus) without cache in the third level. It is possible to assume that AMD will use Deneb crystals with some disabled cache for the production of athlon X4 6xx processors , but here associate reports that Propus processors models already exist, and their core area is equal to 141 sq. mm. let us note that Deneb processors with 6 Mb cache in the third level have an area  243 sq. mm. If the dual core processors Regor will also obtain an original crystal, then their area will be approximately equal to 80 sq. mm. Let us recall that 65 NM processors core 2 Duo e6xxx (Conroe) had a close core area - 143 sq. mm, in this case they had a dual core structure and only 4 Mb cache in the second level. Core 2 Duo e8xxx (Wolfdale) processors  , produced on 45 NM technologies, have an area 107 sq. mm and 6 Mb cache in the second level. The four core processors core i7 (Bloomfield) have a crystal area 246 sq. mm. thus, Propus processors  can be recognized as relatively compact and advantageous in the production.

POSTER: computer news   ||   SAMSUNG NC20	DATE:2008-12-22
Associate reported today about the successor of mobile PC Samsung NC10. In this case we deal with Samsung NC20. This compact computer will be equipped with 12,1 inches screen, and it will be made on VIA nano u225 processor (not Intel atom, 1,6 GHz as in NC10), whose frequency is modest 1,3 GHz. The notebook will be equipped with 1 GB memory and have a 160 GB HDD . This Samsung notebook support Bluetooth 2.0, wireless interface wi-Fi (IEEE 802.11 b/g) and Also 1,3-Mp Web- camera and card reader 3- in -1. According to our associate  the weight of notebook is equal to 1,5 kg, and its price is 642 dollars. or 450 Euros. Official Samsung NC20 release will take place during February 2009.

POSTER: computer news   ||   PHENOM X4 II VS PHENOM X4	DATE:2008-12-21
We already reported that the performance of phenom X4 II exceeds Phenom X4 by 5-15%, depending on the task type  . The considerable superiority degree is ensured by the cache in the third level , increased from 2 to 6 Mb.   AMD, published a complete list of differences in the new Phenom X4 II from the old Phenom X4: 45 NM technological manufacturing process, allow  to increase the core clock frequencies and to decrease currents leakage . Increased cache in the third level. Most noticeable for user change. It will increase the performance in the dependant on cache volume  tasks, such as games. Cache access time ( the third level ) was reduced by 2 times. this will give a small acceleration. Increase in the memory capacity .  If we examine the server versions shanghai and Barcelona core, then Shanghai can support DDR 2-800, while Barcelona is limited to DDR 2-667 support. Furthermore, the memory controller in k10  processors works at separate frequency, which is lower than the core frequency . The L1 and L2 caches are copied in L3 cache, and the core being located in the economical regime, consumes less energy than predecessor. The predictor of indirect passages appeared. Thus, the effectiveness of predictor will be a little improved. Two-fold increase in the capacity of  protocol demands , maintenance of caches coherence  . This will allow  to increase the performance in multi-threaded tasks. Increased buffer devices , floating-point calculations. Let us leave the remained changes without commentaries, since they are completely specific: Increased performance in a number of cases with the use of LOCK prefix . Improved performance of displacement instruction with floating points between the processor registers  . It is worthwhile to note that different improvements in the core micro-architecture, are capable of ensuring, on average, only 3% of advantage in comparison with Agena core  , and basic increase is ensured by the cache and increased clock frequencies.
