AMD Llano A8-3850 vs Intel Core i3 2120

I have recently been looking at the performance of the new AMD Llano CPU's. Having looked at a few benchmark videos and bench mark results I decided to compare an Intel CPU and an AMD CPU that both cost the same amount of money (well as close as I could get on the eBuyer website)
The two CPU's I chose were the AMD Llano A8-3850 and the Intel Core i3 2120 CPU. Both of which are of the latest CPU's from each company and both cost around the same sort of price. The intel CPU being £6 more. Here are the 2 CPU's on the eBuyer website;

AMD Llano A8-3850 Specifications
Core Speed - 2.9Ghz
Number of cores - 4
Number of threads - 4
Cache - 4mb
Intergrated Graphics - 6550D
Graphics Frequency - 600MHz

Intel Core i3 2120 Specifications
Core Speed - 3.3GHz
Number of core - 2
Number of threads - 4
Cache - 3Mb
Intergrated graphics - Intel HD 2000
Graphics Frequency - 850Mhz

As you can see the AMD CPU has 4 real cores whereas the Intel CPU only has 2 real cores and Hyper Threading. This might make a noticeable difference in the CPU benchmarks later on.

I first went on the the CPU benchmark site called www.cpubenchmark.net this site has bench marks for pretty much every CPU that there is and is based on results that are got from it's own benchmark program called Passmark Performance test. Every time someone runs the program it uploads the results from the CPU and graphics card tests to this website. These are the benchmark results for both of the CPU's. Bearing in mind that the graphics side of the chips are not taken into account on this test.

AMD Llano A8-3850 - 4786
Intel Core i3 2120 - 3943

As you can see the AMD is already way ahead with basic CPU performance. It is around 21% faster for £6 less cost. This clearly makes the A8-3850 a better option for just CPU performance.

Now I am going to look at the graphical performance of each CPU. I couldn't find much data really about the graphics performance however I did find a couple of videos of each CPU running  games. (I know the intel one is based on the 2100 but that is because I couldn't find 2120 specific results)

Here is the AMD Llano A8-3850 running Crysis 2 without the aid of a graphics card


Here is the Intel Core i3 2120 running Dirt 3 without a graphics card



As you can see the Intel CPU is running the graphics on low with a resolution of only 1024x768 which is pretty feeble. The AMD A8-3850 is running Crysis 2 (known for being demanding) It is also running a second benchmark program in the background of the game loading 2 of the cores to 100% as well.

Overall I think that AMD have really hit the spot with the new APU series of processors that they have developed. They are definatly cheaper than the Intel equivalent and also seem to offer some very good performance as well. If AMD carry on this way with there higher performance CPU's in the future I am pretty sure that they will earn a lot of money of this great design.
