January 2nd, 2011 No comments


The AMD’s Athlon ii X2 255 is clocked at 3.1 GHz, and is a dual core processor for moderate to high end computing. Its low cost and ability to fit in the existing AM2+ and AM3 motherboard socket makes it attractive.

The Athlon ii 255 has 1 MB of L2 cache to each of the two cores giving it a total of 2 MB of L2 cache. The Athlon II X2 255 has integrated memory controller which reduces the processor to memory latency and increases the processor to memory speed. This is one area where Athlon ii 255 processor will perform better than the Intel Core 2 processor from Intel. The Integrated Memory controller partly makes up for the lacuna created by low L2 cache.

The communication with the chipset is using fast HyperTransport differential Bus at 2 GHz.

Base upon the Regor Core, the Athlon ii X2 255 is built with 45 nm technology and consists of 234 million transistors. It supports many other features including the AMD virtualization technolofy and the 64 bit supprt. The Virtualization technology helps if we have multiple operating systems running. The Athlon ii X2 255 also has support for the advanced multimedia instructions which include AMD’s SSE4a instructions ( Intel has its own SSE4.1 and SSE4.2 instruction sets).

The Athlon ii X2 220 at 2.80 GHz has been more popular in the Regor core. Howeverm you can expect a 10% performance improvement with the Athlon ii X2 255 as compared to the Athlon ii X2 220

January 1st, 2011 No comments


The AMD Athlon-II X4-640 is a quad core processor clocked at 3.0 GHz. The L2 Cache is 2 MB ( 512KB for each of the 4 cores). The Athlon ii X4 640 has an integrated Memory controller, which  reduces the latency in the processor to memory communication and makes the processor to memory communication fast.  The fast integrated memory controller partly makes up for the smaller cache memory.

The L1 Cache is 64 KB of instruction cache and 64 KB of data cache for all the four core. This makes up a total of 256 KB of L1 instruction cache and 256 KB of data cache.

The Athlon II X4 640 communicates with the chipset using high speed differential HyperTransport bus at 2 GHz. The Hypertransport Bus has massive bandwith with eases up the bottleneck in the processor to peripheral communication. AMD was pioneer in design and use of the Integrated memory controlled as well as the differential HyperTransport Bus. Intel later on used the same technology with its core i3 and core i5 processors.

The Athlon ii X4 640 will fit in your existing motherboard with AM2+ and AM3 socket. AMD has done some commendable job, knowingly or unknowingly in bringing out a large number of processors that come under one umbrella as far as the compatibility to the AM2+ and AM3 motherboards are concerned. If you have a relatively old processor and you need to upgrade the performance, it is likely that replacing with the sub $100, Athlon ii X4 640 will do the job for you.

The TDP rating of the Athlon ii X4 640 is relatively high at 95 Watts. This means the it will require some decent cooling arrangement as far as the heatsink and fans are concerned.

Other notable features include 64 bit support, AMD virtualization support, and the support for the multimedia instructions, including the latest SSE4a. Notice that while the Intel processors support the both SSE4.1 and SSE4.2, AMD has its own proprietary implementation that it calls SSE4a.

The Athlon ii Series of processors give decent performance at acceptable cost point. You may also like to consider the bigger brother, Athlon ii X4-645, which is the fastest quad core Athlon II processor at the time of writing. The Athlon ii X4 645 bumps up the frequency by 100 MHz, giving you additional performance improvement of the order of 3%.

High end gamers who typically use dual core will benefit by switching to the quad core Athlon ii X4 640, and the good news is, they can do so, without spending too much. The Athlon ii X4 640 is a sub $100 processor, making it a competitor to the more expensive core i5 processors.


AMD Athlon II X4 640 Benchmark

Several benchmarks have proved that AMD Athlon II X4 640 has decent performance level as compared to the similarly priced core i3 and core i5 processors from Intel. The passmark ( Performance test 6.1) score of Athlon II X4 640 has been found to be 2392 which is marginally lower than much more expensive Intel core i7-920’s score of 2688.

AMD V Series V160 processor

January 1st, 2011 No comments

The AMD V Series V160 is a single core processor with  a clock frequency of 2.4 GHz. The V Series V160 is also called as Sempron V160 and the terms are interchangeably used.

The V Series V160 is intended for the entry level notebooks and netbooks, that should be good enough for the home and office computing, including emails, office and spreadsheets, surfing. However, since it is only a single core processor, it will not match the performance of the dual core processors, for example, the Athlon ii P320 or the Intel’s core i3 processors.

The V Series V160 will have 512KB of L2 ache memory, which not great but suitable for the low memory intensive tasks. The V Series V160 has integrated Dual-channel 533 MHz DDR3 Integrated  Memory controller. The Integrated Memory Controller makes the processor to memory communication fast. The Intel core 2 architecture, for example, communicates to memory through a chipset ( Called North Bridge) which increases the memory latency and degrades the overall performance.

The fast integrated memory controller partially makes up for the lack of the cache memory in the V160. The TDP rating of the AMD V series V120 processor is low at 25 Watt , which makes it suitable in the design of the small and low power notebooks.


AMD V Series V160 Processor Pros

– Low cost processor.
– Low power, great for long battery life.
– Integrated DDR3 Memory Controller.

AMD V Series V160 Processor Cons

– Not suitable for high end computing.
– No L3 Cache, only 512 KB L2 Cache.

 

Older and Less important Facts

Riding on the success of its V140 processor, AMD plans to launch its successor V Series V160 processor.The V Series V160 improves upon the clock frequency of V140 by 100 MHz or 4.3%. We should therefore see an improvement in the processor intensive task by an order of 4%.

AMD Phenom ii X6 1100T introduced

December 13th, 2010 No comments

The hex core phenom ii X6  1100T became the highest frequency Phenom ii hex processor, when AMD introduced it recently. The Phenom ii X6 1100T has a clock frequency of 3.30 GHz, up from 3.2 GHz from its predecessor Phenom ii X6 1090T. Its turbo frequency also gets speed bump from 3.6 GHz of 1090T to 3.7 GHz of 1100T. Notice that the Turbo is active only if 3 or less cores are active.

The Phenom ii X6 1100T is competitively priced at $265 ( at the time of writing). By comparision its predecessor 1090T has been priced at $235.

Comparing by price, we find Intel Core i7-860 ( 2.8 GHz, Turbo 3.46 GHz,  4 core, 8 Hyperthreads) to be priced at $285 ( source – http://ark.intel.com/Product.aspx?id=41316) – which is slightly higher than AMD’s hex core 1100T. The performance of the  Intel Core i7-860 is marginally better in some application, but, in multi threaded environment, the six cores of AMD’s 1100T gives out an edge. Intel Core i5-760 ( 2.8 GHz, quad core,  turbo 3.30 GHz) could be another competitor, which at $205 seems fairly priced and is only slightly behind 1100T.

You may like to note that the 1100T belongs to the Black Edition, which means that it offically supports overclocking. In lab tests, the 1100T has been found to be stable at 3.89 GHz and can occassionally cross 4 GHz. It will be a delight to the overclockers and gamers who wish to take advantage of it. Overclocking may require increase in the processor core voltage which may overheat the processor.
