AMD Athlon ii P340 Vs Pentium Dual Core T4500

March 31st, 2011 Leave a comment Go to comments

The AMD’s Athlon ii P340 and the Intel Pentium Dual Core T4500 make up an interesting compatison. The clock frequencies are similar – the Athlon P340 is clocked at 2.2 GHz while the T4500 is clocked at 2.3 GHz.  It turns out that the Athlon ii’s exotic Integrated Memory controller is not good enough to make it a better processor when the  benchmarking results are compared. The higher 2.3 GHz clock frequency of the Dual core T4500 weighs heavily and does not let the 2.2 GHz P340 go past it. The gap between the performance is not huge, but if you need a yes or no answer, then T4500 is faster.

Before we  compare the benchmark results of the Athlon ii P340 with Dual Core T4500, let us take a look at the qualitative comparison of the P340 with T4500

– Both the Athlon ii P340 as well as the Dual Core T4500 are dual core. While P340 is clocked at 2.2 GHz, the T4500 is clocked at 2.3 GHz.

– The Athlon ii P340 has integrated memory controller, which speeds up the processor to memory controller. The memory DIMM module connect to the processor directly. This is unlike the Intel’s T4500 architecture, in which, the processor first communicate with the North Bridge, which in turn communicates with the Memory. This slows down the processor to memory communication.

– Both the Athlon ii P340 as well as the T4500 have 1 MB of L2 Cache.
– The Athlon ii P340 communicates with the chipset using fast differential HyperTransport Bus. The Intel’s Dual core T4500 communicated with Front Side Bus.

Given these facts, it is difficult to arrive at a quick decision as to which of these two is faster. The Table below lists out some of the bench marking results.

Benchmark Athlon ii P340 Dual Core T4500
Super Pi 2M (Lower is better) 72 seconds 63 seconds
Windows 7 Experience Index – CPU 5.3 5.8
PassMark Score 1313 1563
3D Mark 06 CPU Score 1740 1920

From the Table, it is obvious that the Intel’s Dual core T4500 has better performance than the Athlon ii P340, though the margin is not very high. Obviously the Athlon ii P320 lags behind by even farther margin when compared to T4500
