Nokia’s fastest mobile devices? – Nokia Mobile processors comparison

You might get surprised by the below numbers. A day after N97 was announced in I wanted to see how different are the high end ones different from the other models of Nokia’s Nseries and ESeries models. Here are the findings. Surprisingly N97 doesn’t have fastest processor and also it is marginally better than that of N95.

Generally the Eseries models had better and faster processors than their costlier Nseries counterparts. Below is the list of processor CPU speeds for Latest Nokia mobiles. The Nokia model with fastest CPU are E52 and E55. The N96 has dual processors (2 ARM 9) . Though the CPU itself is not the only criteria in pricing of the models, but costliest model N97 has a reasonably lower CPU speed than E52 which 50% of N97’s price.

Same with E71 and E63. E63 is exact replica of E71 except GPS and 3G.

Nokia E52 – ARM 11 – 600 MHz

Nokia E55 – ARM 11 – 600 MHz

Nokia N97 – ARM 11 – 434 MHz

Nokia N86 8MP – ARM 11 – 434 MHz

Nokia N96 – ARM 9 – 2 * 264 MHz

Nokia N79 – ARM 9 – 2 * 220 MHz

Nokia E63 – ARM 11 – 369 MHz

Nokia E71 – ARM 11 – 369 MHz

Nokia N79 – ARM 11 -369 MHz

Nokia E75 – ARM 11 – 369 MHz

Nokia N85 – ARM 11 – 369 MHz

Nokia N95 8GB – ARM 11 – 332 MHz

Nokia N82 – ARM 11 – 332 MHz

The three processors Intel® Core™2 Quad Processor Q8200, Q9400 and Q9550, are the three options most Desktop buyers would be looking to choose between (Sorry for the AMD users, we will come back to AMD comparison soon) if they are looking for Quad Cores. All these processors have four cores and are in the entry to mid level of the Quad Core segment (All in premium end of overall processors). Price wise all of them fall in medium to premium segment costing between $150-$260 on their own ( Rs 9000.00 to Rs 15000.00 INR )
The highlights of these three processors are they all follow 45nm architecture, 95W power consumption and all are supported in LGA775 socket. So you can choose your motherboard and decide between these three procesors. All these processors use 1333 MHZ System Bus.
The main difference is the processor speed at 2.33GHZ, 2.66GHz and 2.83 GHz respectively which isn’t a big difference for the cost. Other significant difference in terms of technical details is the Cache which is 4MB L2, 6MB L2 and 12 MB L2 for processors Intel® Core 2 Quad Processor Q8200, Q9400 and Q9550 respectively. But the performance improvement of the increased cache can be hardly felt as most hardware experts say beyond 2MB L2 cache the difference in performance is minimal.
When we check the performance of the processor as per CPU benchmark results the results are very much progressive.

Intel vs AMD – Desktop Quad Core Processors comparison – Price vs Performance ratio

The performance/Price ratio is the third column and the bigger the number means you are getting better value for your money.The AMD processors show a reasonably better value than Intel. Intel’s Q8200 is a good value for money chip. These values are based on current retail prices ( May 29 2009) in the assembled computer market.

Processor Name CPU Benchmark value Performance/Price (bigger the better)

Intel Core 2 Quad Core Q9550 – 4179 – 0.28 (Performance / Price ratio , Bigger the better)
Intel Core 2 Quad Core Q9400 – 3643 – 0.29
Intel Core 2 Quad Core Q8200 – 3183 – 0.36
Intel Core 2 Duo E7400 – 1852 – 0.31
Intel Core 2 Duo T9400 (laptop) – 1699 – NA
Dual Core E5400 – 1606 – 0.47 (Best Performance/Price ratio)

To put things into perspective let me give some more common numbers

the top of the line laptop processor Intel Core 2 Duo T9400 has benchmark value of 1699.So its not giving half the performance of its desktop counterparts.

Now lets look at AMD lineup for reference

AMD Phenom X4 9650 – 2615 – 0.39
AMD Phenom X4 9850 – 2790 – 0.33
AMD Phenom X4 9950 – 3016 – 0.35
AMD Phenom X4 920 – 3290 – 0.31
AMD Phenom X4 940 – 3788 – 0.35

The price vs Performance ratio comparisions show AMD X4 9650, AMD Phenom X4 9850 are doing good. But the best numbers are there for Intel Quad Core Q8200.
