AMD Turion ii N550 Processor

Turion ii N560 is a dual core 2.6 GHz processor that gives out decent performance of for the notebooks intended for home or office use.

The AMD’s processors offer decent level of performance at an affordable cost. This is what make them compete against the more powerful Intel. The Turion ii N550 has integrated memory controller and this is what makes them more attractive as compared to the Intel core 2 processor. The integrated memory controller reduces the memory latency and increases the overall performance. This is unlike the Intel’s core 2 processors, which first communicates with a chipset, which, in turn communicates with the memory.

The Turion ii N550 has 2 MB of L2 Cache ( 1 MB for each core). AMD makes up for small L2 cache and missing L3 cache with its fast integrated memory controller. It ensures that the “cache miss”, does not lead to too much penalty when it has to get the data from the memory in place of Cache.


The Turion ii however, has inferior performance compared to the similarly clocked Intel Core i3 processor. It is also inferior to its own Phenom ii processors and the Intel core i5 processors, mainly because of the absence of the turbo boost. If you are looking for high performance notebook computing, you may like to head to the Intel Core i5 or the dual core, triple core and quad core AMD Phenom ii Processor. The Turion ii N550 will howeverr, offer price advantage.

The Turion ii N550 steps up the frequency of the Turion ii N530 ( 2.5 GHz processor) by 100 MHz or 4%. We should therefore expect a performance improvement of the order of 4% in processor intensive tasks in Turion ii N5550 as compared to the Turion ii N550. This may not be significant enough. However, compared with the Turion II P540 , a more popular 2.4 GHz processor, the performance advantage of about 8% could be significant.

Built with 45 nm technology, the Turion ii N550 supports virtualization technology and support 64 bit instruction sets. The virtualization technology will help you if you are running multiple operating system in the same machine. The 64 bit instruction set make software take advantage of the faster 64 bit execution.

The communication with the chipset is using fast differential HyperTransport Bus, at 1800 MHz. The Hypertransport Bus makes processor to chipset and peripheral communication fast and eases the bottleneck that earlier front side Bus ( still found in Intel core 2 processor).

Benchmarking results for the AMD Turion ii N550 is not available at the time of writing.
